[Objectives]To observe the clinical efficacy of Dingjing Pills on patients with schizophrenia accompanied by risky behaviors.[Methods]Two hundred patients diagnosed with schizophrenia and risky behaviors were divided into two groups based on the random and double-blinded principle:the treatment group(100 cases)treated with Dingjing Pills combined with risperidone,and the control group(100 cases)treated with risperidone alone.The observation course was 6 weeks.The clinical efficacy was compared using brief psychiatric rating scale(BPRS),modified overt aggression scale(revised edition)(MAOS),treatment emergent symptom scale(TESS),and blood routine,liver function,kidney function,and electrocardiogram examinations were conducted.[Results]After treatment,Dingjing Pills significantly reduced the scores of brief psychiatric rating scale,modified overt aggression scale and treatment emergent symptom scale in patients with schizophrenia and dangerous behaviors,and had no significant toxic or side effects.The total effective rate in the treatment group was 88.8%,while the total effective rate in the control group was 77.1%.There was a significant difference in therapeutic efficacy between the two groups(P<0.05).[Conclusions]Dingjing Pills has an intervention and therapeutic effect on high-risk behaviors of schizophrenia,with minimal side effects and easy acceptance by patients.

Packed with pills-obstructing duodenal web in the setting of intestinal malrotation:A case report

BACKGROUND The incidence of intestinal malrotation in adults has been reported to only be about 0.2%.Duodenal web as a cause of intestinal obstruction is rare,with an incidence of about 1:20000-1:40000.Furthermore,when described,these conditions are usually seen in early life and very infrequently in adulthood.CASE SUMMARY We report a case of a middle-aged woman with intestinal malrotation who presented with a three-month history of right-sided abdominal pain,early satiety,and a 22-pound weight loss.Patient underwent an esophagogastroduodenoscopy,which demonstrated numerous retained pills in a deformed first portion of the duodenum,concerning for a partial gastric outlet obstruction.An upper gastrointestinal series showed marked distention of the proximal duodenum with retained debris and the presence of a windsock sign,increasing the suspicion of a duodenal web.The patient subsequently underwent surgical intervention where a duodenal web with two lumens was noted and resected,opening the duodenum.There were over 150 pill capsules that were removed.The patient is doing well after this intervention.CONCLUSION Both intestinal malrotation and duodenal webs are infrequently encountered in the adult population.These pathologies can also present with nonspecific abdominal symptoms such as chronic abdominal pain and nausea.Hence,providers might not consider these pathologies in the differential for patients who present with vague symptoms which can lead to delay in management and increased mortality and morbidity.

Effect of Shoutai Pills on Th1/Th2 Cytokines in Serum and Endometrium of Rats with Stimulated Ovulation

In our previous study,we found that Shoutai pills could improve the embryo implantation rate as well as the levels of estrogen,progesterone and estrogen receptor in rats with stimulated ovulation.However,the mechanism is not clear.This study was designed to investigate the effect of Shoutai pills on the levels of Th1 and Th2 cytokines in rats with stimulated ovulation and the mechanism.The rat model of stimulated ovulation was established by combined injection of pregnant mare serum gonadotropin(PMSG)and human chorionic gonadotropin(HCG).Then the rats were randomly divided into model group(M),Shoutai pills group(S),progesterone group(P)and normal group(N).All the pregnant rats were treated from the first day.The S and P groups were administrated with gavage of Shoutai pills and injection of progesterone respectively,and N and M groups were given the same volume of normal saline and distilled water respectively.After treatment for 7 days,the animals were executed for serum and uterine tissues.The ELISA method was adopted to detect the contents of Thl cytokines[interferon-γ(INF-γ),interleukin-2(IL-2)]and Th2 cytokines(IL-4,IL-6,IL-10).The expression of leukemia inhibitory factor(L1F)and leukemia inhibitory factor receptor(LIFR)was detected by Western blotting and real-time PCR.As compared with N group,the expression levels of IFN-y and IL-2 in M group were significantly increased,and those of IL-4,IL-6,IL-10.LIF and LIFR were significantly decreased(P<0.05).As compared with M group,the levels of IL-4,IL-6,IL-10,LIF and LIFR in S group were significantly increased(P<0.05),and those of IFN-γand IL-2 were significantly decreased(P<0.05).It was suggested that Shoutai pills can increase the levels of IL-4.1L-6,IL-10,LIF and LIFR as well as reduce the levels of INF-γand IL-2 in rats with stimulated ovulation.The Shoutai pills may improve endometrial receptivity and promote embryo implantation by maintaining the balanee of Th1/Th2 cytokines.

Shuyu pills inhibit immune escape and enhance chemosensitization in hepatocellular carcinoma

BACKGROUND Hepatocellular carcinoma(HCC)is characterized by dysregulation of the immune microenvironment and the development of chemoresistance.Specifically,expression of the programmed cell death protein 1(PD-1)/programmed cell death 1 ligand 1(PD-L1)axis,an immune checkpoint,may lead to tumour immune escape,resulting in disease progression.The latest research shows that tumour immune escape may be caused by the upregulation of PD-L1 mediated by hypoxia-inducible factor-1 alpha(HIF-1α),and simultaneous inhibition of HIF-1αand PD-L1 has the potential to enhance the host’s antitumour immunity.Moreover,inhibition of the PD-1/PD-L1 axis may mitigate tumour chemoresistance.Shuyu pills(SYPs)contain immunity-enhancing and antitumour components,making them a potential HCC treatment.AIM To investigate the efficacy of SYPs for HCC treatment via simultaneous HIF-1α and PD-L1 inhibition and the mechanism involved.METHODS A subcutaneous xenograft tumour model was first established in BALB/c nude mice by the subcutaneous injection of 1×107 SMMC-7721 cells.Male mice(male,5 weeks old;n=24)were then randomly divided into the following four groups(n=6):Control(0.9%normal saline),SYP(200 mg/kg),SYP+cisplatin(DDP)(200 mg/kg+5 mg/kg DDP weekly via intraperitoneal injection),and DDP(5 mg/kg cisplatin weekly via intraperitoneal injection).The dose of saline or SYPs for the indicated mouse groups was 0.2 mL/d via intragastric administration.The tumour volumes and body weights of the mice were measured every 2 d.The mice were euthanized by cervical dislocation after 14 d of continuous treatment,and the xenograft tissues were excised and weighed.Western blot assays were used to measure the protein expression of HIF-1α,PD1,PD-L1,CD4+T cells,and CD8+T cells in HCC tumours from mice.Quantitative reverse transcription polymerase chain reaction was used for real-time quantitative detection of PD-1,PD-L1,and HIF-1α mRNA expression.An immunofluorescence assay was conducted to examine the expression of CD4+T cells and CD8+T cells.RESULTS Compared to mice in the control group,those in the SYP and SYP+DDP groups exhibited reduced tumour volumes and tumour weights.Moreover,the protein and mRNA expression levels of the oncogene HIF1α and that of the negative immunomodulatory factors PD-1 and PD-L1 were decreased in both the SYP and SYP+DDP groups,with the decrease effects being more prominent in the SYP+DDP group than in the SYP group(HIF-1α protein:Control vs SYP,P=0.0129;control vs SYP+DDP,P=0.0004;control vs DDP,P=0.0152,SYP+DDP vs DDP,P=0.0448;HIF-1αmRNA:control vs SYP,P=0.0009;control vs SYP+DDP,P<0.0001;control vs DDP,P=0.0003,SYP vs SYP+DDP,P=0.0192.PD-1 protein:Control vs SYP,P=0.0099;control vs SYP+DDP,P<0.0001,SPY vs SYP+DDP,P=0.0009;SYP+DDP vs DDP,P<0.0001;PD-1 mRNA:control vs SYP,P=0.0002;control vs SYP+DDP,P<0.0001;control vs DDP,P=0.0003,SPY vs SYP+DDP,P=0.0003;SYP+DDP vs DDP,P=0.0002.PD-L1 protein:control vs SYP,P<0.0001;control vs SYP+DDP,P<0.0001;control vs DDP,P<0.0001,SPY vs SYP+DDP,P=0.0040;SYP+DDP vs DDP,P=0.0010;PD-L1 mRNA:Control vs SYP,P<0.0001;control vs SYP+DDP,P<0.0001;control vs DDP,P<0.0001,SPY vs SYP+DDP,P<0.0001;SYP+DDP vs DDP,P=0.0014).Additionally,the quantitative and protein expression levels of CD4+T cells and CD8+T cells were simultaneously upregulated in the SYP+DDP group,whereas only the expression of CD4+T cells was upregulated in the SYP group.(CD4+T cell quantitative:Control vs SYP+DDP,P<0.0001,SYP vs SYP+DDP,P=0.0005;SYP+DDP vs DDP,P=0.0002.CD4+T cell protein:Control vs SYP,P=0.0033;Control vs SYP+DDP,P<0.0001;Control vs DDP,P=0.0021,SYP vs SYP+DDP,P=0.0004;SYP+DDP vs DDP,P=0.0006.Quantitative CD8+T cells:Control vs SYP+DDP,P=0.0013;SYP vs SYP+DDP,P=0.0347;SYP+DDP vs DDP,P=0.0043.CD8+T cell protein:Control vs SYP+DDP,P<0.0001;SYP vs SYP+DDP,P<0.0001;SYP+DDP vs DDP,P<0.0001).Finally,expression of HIF-1αwas positively correlated with that of PD-1/PD-L1 and negatively correlated with the expression of CD4+T cells and CD8+T cells.CONCLUSION SYPs inhibit immune escape and enhance chemosensitization in HCC via simultaneous inhibition of HIF-1α and PD-L1,thus inhibiting the growth of subcutaneous xenograft HCC tumours.

Neuroprotective effects of Ginkgo biloba dropping pills in Parkinson's disease

Parkinson's disease(PD) is the second most common neurodegenerative disease in the world;however,it lacks effective and safe treatments. Ginkgo biloba dropping pill(GBDP), a unique Chinese G. biloba leaf extract preparation, exhibits antioxidant and neuroprotective effects and has a potential as an alternative therapy for PD. Thus, the aims of this study were to evaluate the effects of GBDP in in vitro and in vivo PD models and to compare the chemical constituents and pharmacological activities of GBDP and the G. biloba extract EGb 761. Using liquid chromatography tandem-mass spectrometry, 46 GBDP constituents were identified. Principal component analysis identified differences in the chemical profiles of GBDP and EGb 761. A quantitative analysis of 12 constituents showed that GBDP had higher levels of several flavonoids and terpene trilactones than EGb 761, whereas EGb 761 had higher levels of organic acids.Moreover, we found that GBDP prevented 6-hydroxydopamine-induced dopaminergic neuron loss in zebrafish and improved cognitive impairment and neuronal damage in methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced PD mice. Although similar effects were observed after EGb 761 treatment,the neuroprotective effects were greater after GBDP treatment on several endpoints. In addition, in vitro results suggested that the Akt/GSK3β pathway may be involved in the neuroprotective effects of GBDP.These findings demonstrated that GBDP have potential neuroprotective effects in the treatment of PD.

Wumei pills attenuates 5-fluorouracil-induced intestinal mucositis through Toll-like receptor 4/myeloid differentiation factor 88/nuclear factor-κB pathway and microbiota regulation

BACKGROUND Radiotherapy and chemotherapy can kill tumor cells and improve the survival rate of cancer patients.However,they can also damage normal cells and cause serious intestinal toxicity,leading to gastrointestinal mucositis[1].Traditional Chinese medicine is effective in improving the side effects of chemotherapy.Wumei pills(WMP)was originally documented in the Treatise on Exogenous Febrile Diseases.It has a significant effect on chronic diarrhea and other gastrointestinal diseases,but it is not clear whether it affects chemotherapy induced intestinal mucositis(CIM).AIM To explore the potential mechanism of WMP in the treatment of CIM through experimental research.METHODS We used an intraperitoneal injection of 5-fluorouracil(5-Fu)to establish a CIM mouse model and an oral gavage of WMP decoction(11325 and 22650 mg/kg)to evaluate the efficacy of WMP in CIM.We evaluated the effect of WMP on CIM by observing the general conditions of the mice(body weight,food intake,spleen weight,diarrhea score,and hematoxylin and eosin stained tissues).The expression of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),IL-1β,and myeloperoxidase(MPO),as well as the Toll-like receptor 4/myeloid differentiation factor 88/nuclear factor-κB(TLR4/MyD88/NF-κB)signaling pathway proteins and tight junction proteins(zonula occludens-1,claudin-1,E-cadherin,and mucin-2)was determined.Furthermore,intestinal permeability,intestinal flora,and the levels of short-chain fatty acids(SCFA)were also assessed.RESULTS WMP effectively improved the body weight,spleen weight,food intake,diarrhea score,and inflammatory status of the mice with intestinal mucositis,which preliminarily confirmed the efficacy of WMP in CIM.Further experiments showed that in addition to reducing the levels of TNF-α,IL-1β,IL-6,and MPO and inhibiting the expression of the TLR4/MyD88/NF-κB pathway proteins,WMP also repaired the integrity of the mucosal barrier of mice,regulated the intestinal flora,and increased the levels of SCFA(such as butyric acid).CONCLUSION WMP can play a therapeutic role in CIM by alleviating inflammation,restoring the mucosal barrier,and regulating gut microbiota.

Protective Effect and Action Mechanism of Modified Ershiwuwei Songshi Pills on Chronic Liver Injury Induced by CCL4

[Objectives]To study the protective effect of Ershiwuwei Songshi Pills on chronic liver injury induced by carbon tetrachloride(CCL4)in rats before and after the modification conforming to the compatibility theory of Tibetan medicine,and to explore its action mechanism.[Methods]Male Wistar rats were randomly divided into the blank control group,model group,Hugan tablets group(0.490 g/kg),Ershiwuwei Songshi Pills group(0.117 g/kg),and Modified Ershiwuwei Songshi Pills group(removing cinnabaris,Aristolochia contorta,and Aconitum naviculare,0.105 g/kg).Except the blank group,the remaining groups were injected subcutaneously with 20%carbon tetrachloride olive oil solution every 3 d,and modeled for 6 weeks.During this time,intragastrically administered corresponding drugs.Six weeks later,blood was taken from the femoral artery,and the rats were killed through dislocating the cervical spine,the liver was taken,and the content of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)was determined.Then,liver fibrosis indicators tumor necrosis factor-α(TNF-α),nuclear factor-κB(NF-κB),interleukin-6(IL-6)and interleukin-1β(IL-1β)were detected by immunohistochemical method.[Results]Compared with the model group,the pathological map of the liver section showed that liver injury was improved in each administration group.The serum ALT and AST contents in rats of each administration group were significantly reduced(P<0.05),and the protein expressions of NF-κB,TNF-α,IL-1βand IL-6 in liver tissue were also reduced by varying degrees(P<0.05).[Conclusions]Ershiwuwei Songshi Pills and its modification group have a protective effect on liver injury induced by carbon tetrachloride.The modified prescription conforms to the compatibility rules of Tibetan medicine.The mechanism may be related to reducing the damage caused by inflammatory factors through regulating the role of inflammatory signaling pathway.Thus,it can be used as a reference for future optimization proposals.

The Protective Effect of Compound Danshen Dripping Pills on Oxidative Stress after Retinal Ischemia/Reperfusion Injury in Rats

Objective: To investigate the effect of Compound Danshen Dripping Pills (CDDP) on oxidative stress after ischemia/reperfusion (I/R) injury in the rat retina. Methods: Adult male SD rats were randomly divided into 3 groups: sham (group A), I/R (group B), and I/R plus CDDP (group C). Retinal ischemia/reperfusion injury (RIRI) was introduced by increasing the intraocular pressure (IOP) to 110 mmHg for 60 min via cannulation into the anterior chamber. Right after the insult, CDDP was administered intragastrically (450 mg/kg/d) for 7 days. The levels of malondialdehyde (MDA), the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in the retinal tissues were determined on d1 and d7 after the ischemic insult. Results: Following ischemia, the MDA levels in group B and group C were significantly higher than those in group A (p < 0.01). CDDP significantly lowered MDA levels in group C when compared with group B (p < 0.01). The activities of SOD, GSH-Px and CAT were higher in group A than in group B and group C (p < 0.01). CDDP could increase the activities of SOD, GSH-Px and CAT remarkably in group C when compared with group B (p < 0.01). Conclusion: CDDP can protect the retina from I/R injury through reducing oxidative stress, and thus may be a promising method for the treatment of ischemic retinal disorders.

Xihuang pills induce apoptosis in hepatocellular carcinoma by suppressing phosphoinositide 3-kinase/protein kinase- B/mechanistic target of rapamycin pathway

BACKGROUND The phosphoinositide 3-kinase/protein kinase-B/mechanistic target of rapamycin(PI3K/Akt/mTOR) signalling pathway is crucial for cell survival, differentiation, apoptosis and metabolism. Xihuang pills(XHP) are a traditional Chinese preparation with antitumour properties. They inhibit the growth of breast cancer, glioma, and other tumours by regulating the PI3K/Akt/mTOR signalling pathway. However, the effects and mechanisms of action of XHP in hepatocellular carcinoma(HCC) remain unclear. Regulation of the PI3K/Akt/mTOR signalling pathway effectively inhibits the progression of HCC. However, no study has focused on the XHPassociated PI3K/Akt/mTOR signalling pathway. Therefore, we hypothesized that XHP might play a role in inhibiting HCC through the PI3K/Akt/mTOR signalling pathway.AIM To confirm the effect of XHP on HCC and the possible mechanisms involved.METHODS The chemical constituents and active components of XHP were analysed using ultra-performance liquid chromatography-quadrupole time of flight mass spectrometry(UPLC-Q-TOF-MS). Cellbased experiments and in vivo xenograft tumour experiments were utilized to evaluate the effect of XHP on HCC tumorigenesis. First, SMMC-7721 cells were incubated with different concentrations of XHP(0, 0.3125, 0.625, 1.25, and 2.5 mg/mL) for 12 h, 24 h and 48 h. Cell viability was assessed using the CCK-8 assay, followed by an assessment of cell migration using a wound healing assay.Second, the effect of XHP on the apoptosis of SMMC-7721 cells was evaluated. SMMC-7721 cells were stained with fluorescein isothiocyanate and annexin V/propidium iodide. The number of apoptotic cells and cell cycle distribution were measured using flow cytometry. The cleaved protein and mRNA expression levels of caspase-3 and caspase-9 were detected using Western blotting and quantitative reverse-transcription polymerase chain reaction(RT-qPCR), respectively.Third, Western blotting and RT–qPCR were performed to confirm the effects of XHP on the protein and mRNA expression of components of the PI3K/Akt/mTOR signalling pathway.Finally, the effects of XHP on the tumorigenesis of subcutaneous hepatocellular tumours in nude mice were assessed.RESULTS The following 12 compounds were identified in XHP using high-resolution mass spectrometry:Valine, 4-gingerol, myrrhone, ricinoleic acid, glycocholic acid, curzerenone, 11-keto-β-boswellic acid, oleic acid, germacrone, 3-acetyl-9,11-dehydro-β-boswellic acid, 5β-androstane-3,17-dione, and 3-acetyl-11-keto-β-boswellic acid. The cell viability assay results showed that treatment with 0.625mg/mL XHP extract decreased HCC cell viability after 12 h, and the effects were dose-and timedependent. The results of the cell scratch assay showed that the migration of HCC cells was significantly inhibited in a time-dependent manner by the administration of XHP extract(0.625mg/mL). Moreover, XHP significantly inhibited cell migration and resulted in cell cycle arrest and apoptosis. Furthermore, XHP downregulated the PI3K/Akt/mTOR signalling pathway, which activated apoptosis executioner proteins(e.g., caspase-9 and caspase-3). The inhibitory effects of XHP on HCC cell growth were determined in vivo by analysing the tumour xenograft volumes and weights.CONCLUSION XHP inhibited HCC cell growth and migration by stimulating apoptosis via the downregulation of the PI3K/Akt/mTOR signalling pathway, followed by the activation of caspase-9 and caspase-3.Our findings clarified that the antitumour effects of XHP on HCC cells are mediated by the PI3K/Akt/mTOR signalling pathway, revealing that XHP may be a potential complementary therapy for HCC.

Erzhi pills ameliorates cognitive dysfunction and alter proteomic profiles of hippocampus in ovariectomized Alzheimer disease model rats induced by D-galactose and Aβ1-40 injection

OBJECTIVE Erzhi pills is a clas⁃sic prescription of Chinese medicine originated from Fu Shou Jing Fang in Ming dynasty,with the effects of nourishing kidney-Yin and hemosta⁃sis,black hair,strengthening muscles and bones.As a classical prescription for nourishing kidney-Yin,Erzhi pills has been used to treat senile dementia in China for many years.Herein,our study aimed to investigate the protective effects of Erzhi pills in rat models of Alzheimer disease(AD)induced by ovariectomy as well as D-galactose and Aβ1-40 injection and to explore its potential mechanism.METHODS The model of AD rats was established by ovariectomy com⁃bined with D-galactose and Aβ1-40 injection.Ovariectomized rats were randomly divided into four groups:model group,estradiol valerate(0.80 mg·kg-1)group,Erzhi pills high(1.50 mg·kg-1)and low(0.75 mg·kg-1)doses group.In addition,rats of sham operation were selected as the sham operated group.Except for the sham oper⁃ated group,rats were injected intraperitoneally with D-galactose(100 mg·kg-1 per day,for 49 d)on the 8th day,then they were given intracerebro⁃ventricular injection of Aβ1-40(10μg per rat,1 g·L-1)on the 36th day,while the corresponding drugs were given by gastrointestinal administra⁃tion on the 22nd day.In our study,Morris water maze test was used to evaluate the learning and memory abilities,while ELISA kit was used to an⁃alyze serum estrogen level.The morphology of hippocampal neuron cells was observed by HE staining,and Nissl staining was utilized to ob⁃serve the Nissl body in cytoplasm.Then,the ex⁃pression of ERβpositive cells and hippocampal Aβ1-40 and p-Tau404 proteins was determined by immunohistochemistry.In order to further explore the molecular mechanism of Erzhi pills preven⁃tion and treatment of AD,proteomics was used to find potential targets and related pathways,Western blotting was used to verify the expres⁃sion of candidate differential protein.According to the results of proteomics in our experiment,Western blotting was used to detect the protein expression of PI3K,Akt,Bcl-2,Bcl-xl,Bad,14-3-3 and GSK3β.RESULTS The escape latency was significantly shortened,the number of crossing platform was increased,the neuron arrange⁃ment was more orderly and with less nuclear pycnosis in rats of Erzhi pills groups compared to the model group.In rats treated with Erzhi pills,the number of neurons,Nissl bodies,the estro⁃gen levels and ERβpositive cells were increased,while the number of Aβ1-40 and p-Tau404 positive cells was significantly decreased.Proteomics found that there were more than one hundred differentially expressed proteins of rats treated with Erzhi pills,which were involved in 48 signal⁃ing pathways.Among these proteins,five of them were involved in the PI3K/Akt signal path⁃way.As the down-stream protein of PI3K/Akt sig⁃naling pathway,the content of 14-3-3 protein was significantly increased.Western blotting analysis showed that the expression of p-GSK3β/GSK3βand Bad was decreased,while that of p-Akt/Akt,p-PI3K/PI3K,14-3-3,Bcl-xl and Bcl-2 was up-regulated in rats from the Erzhi pills groups compared with the model group.CON⁃CLUSION Erzhi pills can improve estrogen levels,alter proteomics expression of the hippocampus and activate PI3K/Akt pathway in AD rats,reduce Aβaggregation,inhibit the hyperphos⁃phorylation of Tau protein,maintain the morphol⁃ogy of hippocampal neurons and decrease the apoptosis of hippocampal neurons,thereby improving the learning and memory abilities of ovariectomized AD rats induced by D-galactose and Aβ1-40 injection.This study may provide an experimental basis for the clinical treatment of Erzhi pills.

Protective effect of gingerol dropping pills against alcoholic liver injury in mice

OBJECTIVE To prepare gingerol dropping pills and to investigate its protective effect on alcoholic liver injury. METHODS The prescription was selected by orthogonal design method and the effect of the option and ratio of ground substance,the temperature of drug. The hardness,circular degree,the tail formation and the dissolution time were studied. Totally 40 KM mice were randomly divided into control group,model group,gingerol dropping pill group(400 mg·kg^(-1)·d^(-1)) and positive control group(bifendate,150 mg·kg^(-1)·d^(-1)) of 10 mice each. The mice from the model and two drug groups were administrated with liqueur[0.15 mL/(10 g·d)]daily by gavage for 3 weeks,Two hours later,drug group mice were treated corresponding gingerol dropping pill and bifendate. Meanwhile,the control group were gavaged same amount of normal saline. Finally,when the model of acute alcoholic liver injury was established on the 22 stday,Biochemical indicators of ocular blood in mice were observed.We also observed the change of liver morphology. RESULTS Under optimum conditions,we can obtain dropping pills having circular shape,touching with hardness and short dissolution time. Compared with the control group,the levels of alanine transaminase(ALT),glutamic-oxaloacetic transaminase(AST) and malondialdehyde(MDA) in model group were obviously increased(P<0.01),While the activity of Superoxide dismutase(SOD) were decreased. In addition,In model group,mice liver disorders,hepatic lobule fusion,accompanying a large number of patchy sample liver cell vacuoles,various sizes of fat vacuoles appeared in cytoplasm and inflammatory cell infiltration were visible around the central vein. On the contrary,compared with the model group,drug groups attenuated or even reversed hepatic pathological changes. Form gingerol dropping pill group,an increase in hepatic SOD activity and serum ALT and AST activities were found and a significant decrease in hepatic MDA content were also observed(P<0.01). CONCLUSION The prescription of gingerol dropping pills was reasonable,and the preparation process was simple. Gingerol dropping pills can protect liver from alcoholic liver injury to some extend,and the mechanism may be related to its antioxidant effect.
