Effect of negative mood,serum inflammatory factors,miR-155,and brain-derived neurotrophic factor

BACKGROUND Abdominal postoperative patients are susceptible to postoperative depression resulting from pain and stress,which can hinder their rehabilitation.Acupuncture has shown potential to relieve this condition.AIM To analyze the mechanism by which acupuncture relieves postoperative depression in patients post-abdominal surgery.METHODS Abdominal postoperative patients with depression between January 2015 and December 2023 at the First Affiliated Hospital of Heilongjiang University of Chinese Medicine were enrolled.Patients were divided into two groups using the random throwing method:Observation(250 cases,fluoxetine hydrochloride+acupuncture treatment)and control(250 cases,fluoxetine hydrochloride treatment).Changes in negative emotions Hamilton Depression Scale 24,serum inflammatory factors[tumor necrosis factorα,interleukin(IL)-1β,IL-6],miR-155 expression levels,and BDNF levels were assessed.RESULTS Significant improvements were observed in the observation group compared to the control group in all assessed parameters after six weeks(P<0.05).This suggests that the combination of fluoxetine hydrochloride and acupuncture may be more effective in managing postoperative depression than medication alone.CONCLUSION Acupuncture complies with the principle of traditional Chinese medicine syndrome differentiation and ensures the pertinence and effectiveness of treatment.In addition,it not only actively improves depressive symptoms but also effectively regulates the serum level of inflammatory factors.

Clinical study on microscopic syndrome differentiation and traditional Chinese medicine treatment for liver stomach disharmony in chronic gastritis

BACKGROUND Chronic gastritis(CG)is a common gastrointestinal disorder characterized by inflammation of the stomach lining.Liver-stomach disharmony(LSD)syndrome is believed to contribute to CG symptoms.AIM To evaluate the efficacy and safety of microcosmic syndrome differentiation and Chinese herbal medicine(CHM)treatment in patients with CG and LSD syndrome.METHODS Sixty-four patients with CG and LSD syndrome were randomly divided into two groups:The treatment group received CHM based on microcosmic syndrome differentiation and the control group received conventional Western medicine.The treatment course lasted 12 wk.The primary outcome was improvement in dyspeptic symptoms,measured using the Nepean Dyspepsia Index.The secondary outcomes included the improvement rate of endoscopic findings,histopathological findings,and microcosmic syndrome scores and the incidence of adverse events.RESULTS After 12 wk of treatment,the treatment group showed significantly greater improvement in dyspeptic symptoms than the control group(93.75%vs 65.63%,P<0.01).The treatment group also showed a significantly higher improvement rate in endoscopic findings than the control group(81.25%vs 53.13%,P<0.05).The improvement rates of histopathological findings and microcosmic syndrome scores were not significantly different between the two groups(P>0.05).No serious adverse events were observed in either group.CONCLUSION Microcosmic syndrome differentiation and CHM treatment can effectively improve dyspeptic symptoms and endoscopic findings in patients with CG and LSD syndrome and have a good safety profile.Further studies with larger sample sizes and longer follow-up periods are required to confirm the long-term efficacy and mechanism of action of this treatment.

The Distribution Pattern of Traditional Chinese Medicine Syndromes in Patients with Hyperlipidemia

Objective: Hyperlipidemia is a representative nutritional metabolic disease in clinic, which is easy to induce atherosclerotic cardiovascular and cerebrovascular diseases, with complex classification. Traditional Chinese Medicine (TCM) syndrome aims to reflect the characteristics of diseases and is the basic principle of TCM treatment of diseases. This study aimed to summarize the distribution pattern of TCM syndromes in patients with hyperlipidemia. Methods: The frequency, characteristics and distribution of all TCM syndromes of 1012 patients with hyperlipidemia were analyzed. Results: The main disease types determined by frequency of 1012 patients included hypertriglyceridemia combined with hypo high-density lipoprotein cholesterolemia (19.76%), hypo high-density lipoprotein cholesterolemia (18.58%), hypercholesterolemia (16.50%), mixed hyperlipidemia (16.40%), and hypertriglyceridemia (15.12%). The distribution of TCM syndromes, in order of frequency, was as follows: Qi-deficiency and blood stasis syndrome (23.52%), liver depression and spleen deficiency (9.88%), syndrome of qi stagnation and blood stasis (9.29%), phlegm stasis syndrome (7.41%), and syndrome of yang deficiency of spleen and kidney (6.92%). Conclusion: Qi-deficiency and blood stasis syndrome and liver depression and spleen deficiency are the most common TCM syndromes in patients with hyperlipidemia.

Clinical distribution and molecular profiling on postoperative colorectal cancer patients with different traditional Chinese medicine syndromes

Background:Traditional Chinese medicine(TCM)syndrome,also named syndrome,are comprehensive and integral analyses of clinical information which helps to guide different individualized treatment prescriptions.Methods:Thirty healthy controls and 80 colorectal cancer(CRC)patients(including 33 Spleen Qi Deficiency syndrome,23 Dampness Heat syndrome,17 Blood Stasis syndrome and 7 other syndrome)were enrolled into this study.Human mRNAs were extracted from peripheral blood mononuclear cells.The gene expression for CRC patients with different TCM syndrome was determined by microarray and qRT-PCR.Results:Spleen Qi Deficiency,Dampness Heat and Blood Stasis were the most common syndromes in CRC patients.There is a significant difference was found in mRNA expression levels(especially for PIK3CA,STAT3,SOX9 and KDM5C)among Spleen Qi Deficiency,Dampness Heat and Blood Stasis syndrome groups.The higher mRNA levels of JNK1,TP53,MLH1,MSH6,PMS2,SOCS3,TCF7L2,FAM123B,PSAP,FBXW7,SALL4 and the lower expression of inflammatory cytokine IL-6 were found in Spleen Qi Deficiency group but not other syndrome types.The higher mRNA levels of KRAS,MUC16,EGFR,GRASP65,PIK3CA,MAPK7,CD24,STAT3,SLC11A1,Bcl-2,TXNDC17 and some inflammatory cytokines(IL-6,IL-23,TNF-a,CXCR4)were found in Dampness Heat group but not other syndrome types.Blood Stasis syndrome showed higher expression of SOX9,MLH1,MSH6,KDM5C,PCDH11X,PSAP and SALL4,and lower mRNA levels of PIK3CA,CD24,STAT3,CXCR4,TXNDC17 and TP53.The CRC patients with Dampness Heat syndrome might have a poor prognosis than other syndrome types.Conclusion:The identification of syndrome conditions had different impacts on CRC prognosis,and which might be related with different mRNA expression levels.Some oncogenes and pro-inflammatory cytokines were highly expressed in Dampness Heat group but not other syndrome types,suggesting that the CRC patients with Dampness Heat syndrome might have a poor prognosis.Our results prelimitarily uncovered the molecular basis of syndrome differences in CRC prognosis,a better understanding for TCM treatment of CRC.

The Comparative Study on Two Models of Syndrome Differentiation of the Hand, Foot and Mouth Disease: An Investigation Analysis of the Signs and Symptoms on 2325 Cases

Objective To realize the characteristics of "zheng" differentiation-treatment for hand, foot and mouth disease(HFMD), a new methodology of syndrome differentiation for different stages of HFMD has been explored. Methods Total of 2 325 cases with HFMD were recorded by distributing them into exterior syndrome stage, interior syndrome stage, severe syndrome stage and recovered syndrome stage, respectively, and the main symptoms and subsidiary symptoms of different stages of HFMD have been observed. The major and minor pathogenesis of HFMD in different stages were obtained, and compared with the "2010 Guideline for the Diagnosis and Treatment of HFMD". Results It was found that the major pathogenesis of exterior stage was defined as "the invation of the wenevil to the defender of the body with the collaterals got involved ", and the minor as "qi deficiency"; in interior stage, "the fury of Gan-Yang" was the main pathogenesis, and "qi in chaos and qi deficiency" was the minor; in severe syndrome stage, "the damage of heart, liver and lung" was the main pathogenesis, and "qi in chaos" was the minor; and the pathogenesis of recovered stage was "qi-yin deficiency". Compared with the "2010 Guideline for the Diagnosis and Treatment of HFMD", it showed that "the obstruction of the fei-pi qi by the mixture of shi-re evil" and "the mixture of shi-re" in vivo was quite difficult to be explained in completely different context in the general situation; in the severe stage, the TCM clinical characteristics of syndrome differentiation might lose; in the early acute severe cases, the phenomenon that xin-yang and fei-qi almost ran out was difficult to be observed, then, the line between the severe and the acute severe became vague.Conclusions The theory of syndrome differentiation by stages of HFMD was reasonable in the actual situation of clinical description on HFMD which was expected to be further tested and widely applied in the "zheng" differentiation-treatment of HFMD in the future.

The combination of disease and Zheng (syndrome) on the basic of differentiation of six channels:a new pattern of disease diagnosis and treatment of traditional Chinese medicine

Traditional Chinese medicine(TCM)was formed two thousand years ago,and developed in the following centuries.TCM has a unique way of looking at health and illness.Zheng(syndrome)is the basic unit and key term in TCM theory.Zheng is the pathological generalization of a certain stage in the development of disease.Treatment based on syndrome differentiation and disease differentiation of TCM is the basic principle to know and treat diseases,and a kind of special method to study diseases in TCM.In Han Dynasty(200 AD),doctor Zhang Zhongjing proposed Liujing Bianzheng(the differential diagnosis in accordance with the theory of six channels)to diagnose and treat diseases in Treatise on Febrile and Miscellaneous Diseases.In other words,he divided diseases into six channels diseases based on patient's Zhengs.Six channels diseases almost include all of the disease according to his classification standards.In addition,there are development rules in the progress of six channels diseases.Therefore,we hypothesized that combination of six channels disease and Zheng on the basic of differentiation of six channels is a new pattern of diagnosis and treatment diseases in TCM,which is beneficial to the understanding of a certain disease and makes disease treatment more convenient,fast and effective.

New models of adipogenic differentiation highlight a cell-autonomous response to temperature

Temperature is a key regulator of brown adipose tissue(BAT)function,acting through central sensory inputs to influence metabolism and energy storage.Although animal models have produced a wealth of information on the pathways,effectors and responses mediating the physiological response of adipose tissue to temperature in vivo,the use of cell culture models now offers evidence of an additional cell-autonomous response to temperature changes,in the absence of neural input.In particular,stem cell models provide new insight into the regulation of adipogenic differentiation and the induction of browning features in vitro.Here the basis for adipogenic responsiveness to low temperature is discussed,together with different human cell models available to outline the benefits of cell-based approaches for future BAT research.

Inhibitory effects of patchouli alcohol on stress-induced diarrhea-predominant irritable bowel syndrome

AIM To elucidate the mechanism of patchouli alcohol(PA) in treatment of rat models of diarrhea-predominant irritable bowel syndrome(IBS-D).METHODS We studied the effects of PA on colonic spontaneous motility using its cumulative log concentration(3 × 10^(-7) mol/L to 1 × 10^(-4)mol/L). We then determined the responses of the proximal and distal colon segments of rats to the folowing stimuli:(1) carbachol(1 × 10^(-9) mol/L to 1 × 10^(-5) mol/L);(2) neurotransmitter antagonists including N~ω-nitro-l-arginine methyl ester hydrochloride(10μmol/L) and(1 R~*, 2 S~*)-4-[2-Iodo-6-(methylamino)-9 Hpurin-9-yl]-2-(phosphonooxy)bicyclo[3.1.0]hexane-1-methanol dihydrogen phosphate ester tetraammonium salt(1 μmol/L);(3) agonist α,β-methyleneadenosine 5′-triphosphate trisodium salt(100 μmol/L); and(4) single KCl doses(120 mmol/L). The effects of blockers against antagonist responses were also assessed by pretreatment with PA(100 μmol/L) for 1 min. Electrical-field stimulation(40 V, 2-30 Hz, 0.5 ms pulse duration, and 10 s) was performed to observe nonadrenergic, noncholinergic neurotransmitter release in IBS-D rat colon. The ATP level of Kreb's solution was also determined.RESULTS PA exerted a concentration-dependent inhibitory effect on the spontaneous contraction of the colonic longitudinal smooth muscle, and the half maximal effective concentration(EC_(50)) was 41.9 μmol/L. In comparison with the KCl-treated IBS-D group, the contractile response(mg contractions) in the PA + KCl-treated IBS-D group(11.87 ± 3.34) was significantly decreased in the peak tension(P < 0.01). Compared with CCh-treated IBS-D rat colon, the cholinergic contractile response of IBS-D rat colonic smooth muscle(EC_(50) = 0.94 μmol/L) was significantly decreased by PA(EC_(50) = 37.43 μmol/L)(P < 0.05). Lack of nitrergic neurotransmitter release in stress-induced IBS-D rats showed contraction effects on colonic smooth muscle. Pretreatment with PA resulted in inhibitory effect on l-NAME-induced(10 μmol/L) contraction(P < 0.05). ATP might not be the main neurotransmitter involved in inhibitory effects of PA in the colonic relaxation of stressinduced IBS-D rats.CONCLUSION PA application may serve as a new therapeutic approach for IBS-D.

Relapse of both small cell lung cancer and Lambert-Eaton myasthenic syndrome after a 13-year disease-free survival period

Lambert-Eaton myasthenic syndrome(LEMS) is a paraneoplastic syndrome and only 3%of small cell lung carcinoma(SCLC) patients have LEMS.Moreover,the recurrence of SCLC after a disease-free survival(DFS) of more than 10 years is rare.We report a patient who had a recurrence of both SCLC and LEMS after a 13-year DFS period.A 69-year-old man was diagnosed with LEMS and SCLC(cT0N2M0,stage ⅢA) 13 years ago.Chemoradiotherapy was performed and a complete response was achieved.With anticancer treatment,the LEMS symptoms was alleviated.At the age of 82 years,gait disturbance appeared followed by left supraclavicular lymphadenopathy and further examination revealed the recurrence of SCLC.Careful screening for the recurrence of SCLC might be needed when the patient has recurrent or secondary paraneoplastic neurological syndrome even after a long DFS period.

Regulating effect of Tong Xie-Yao Fang on colonic epithelial secretion via Cl- and HCO3- channel

AIM To investigate the pharmacological effect of Tong XieYao Fang(TXYF) formula, a Chinese herbal formula, on Diarrhea-predominant irritable bowel syndrome(D-IBS) rats.METHODS In a neonatal maternal separation plus restraint stress(NMS + RS) model of D-IBS, male Sprague Dawley rats were randomly divided into two groups(NMS + RS group and TXYF-formula group) with no handlings were used as controls(NH group). Starting from postnatalday 60, rats in TXYF-formula group were administered TXYF-formula(4.92 g/100 g bodyweight) orally twice a day for 14 consecutive days while NH group and NMS + RS group were given distilled water. Using short-circuit current technology, we observed 5-HT-induced changes of current across ion channels, such as cystic fibrosis transmembrane conductance regulator(CFTR) Clchannel, epithelial Na+ channel(ENaC), Ca2+-dependent Cl- channel(CACC), Na+-K+-2Cl- co-transporter(NKCC), and Na+-HCO-3 co-transporter(NBC), in the colonic epithelium of three groups after exposure to drugs and specific blockers with a Power Lab System(AD Instruments International).RESULTS Under basal conditions, the changes of short-circuit current(?Isc, μA/cm2) induced by 5-HT were similar in NH group and TXYF-formula group, and both higher than NMS + RS group(70.86 μA/cm2 ± 12.32 μA/cm2, 67.67 μA/cm2 ± 11.68 μA/cm2 vs 38.8 μA/cm2 ± 7.25 μA/cm2, P < 0.01, respectively). When CACC was blocked by 4,4′-diisothiocyanato-stilbene-2,2′-disulfonic acid, 5-HT-induced ?Isc was smaller in NMS + RS group than in NH group and TXYF-formula group, respectively(48.41 μA/cm2 ± 13.15 μA/cm2 vs 74.62 μA/cm2 ± 10.73 μA/cm2, 69.22 μA/cm2 ± 11.7 μA/cm2, P < 0.05, respectively). The similar result could be obtained when ENaC was blocked by Amiloride(44.69 μA/cm2 ± 12.58 μA/cm2 vs 62.05 μA/cm2 ± 11.26 μA/cm2, 62.11 μA/cm2 ± 12.01 μA/cm2, P < 0.05, respectively). However, when CFTR Cl- channel was blocked by 1,1-dimethyl piperidinium chloride(DPC), 5-HT-induced ?Isc did not significantly differ in three groups(42.28 μA/cm2 ± 10.61 μA/cm2 vs 51.48 μA/cm2 ± 6.56 μA/cm2 vs 47.75 μA/cm2 ± 7.99 μA/cm2, P > 0.05, respectively). The similar results could also be obtained in three groups when NBC and NKCC were respectively blocked by their blockers.CONCLUSION TXYF-formula can regulate the Cl- and HCO-3 secretion of colonic mucosa via CFTR Cl- channel, Cl-/HCO-3 exchanger, NBC and NKCC co-transporters.
