No Evidence of Effect on Male Mice Germ Cells After Acute Treatment With Thiram

Thiram is a dithiocarbamate compound widely used for industrial processes and agriculture. Animal studies reveal that this compound may afftct the male reproductive system. Aim of this study was to test, using sensitive testicular parameters, whether thiram directly affects germinal cells. For this purpose, B6C3F1 mice were intraperitoneally injected with thiram in oil (single dose:75 mg/kg; repeated five daily doses: 25 mg/kg).Although both treatments were toxic, none of the parameters examined, i.e., testis weighi, spermatid head number,specific enzyme levels at different times after treatment (14, 28, 35, 56 days) showed significant variations from the controls, On the contrary, in the positive controls (treated with chlorambucil), a marked reduction of sperm head number as well as a deerease of lactate dehydrogenasex and sorbitol dehydrogenase activity letels were evidenced at day 28, with a tendency to recover at day 35. Under these conditions thiram did not cause cytotoxicity on differentiating spermatogonia and on late spermatocyte stages of mice gonads

Evaluation of modified hemodilution combined therapy in the treatment of acute ischemic stroke in the elderly

BACKGROUND： Thrombolysis therapy is not suitable for the elderly patients with acute ischemic stroke who delayed to be diagnosed for more than 3 hours, but traditional medicine is also not very ideal. OBJECTIVE： To observe the clinical therapeutic effect of modified hemodilution combined therapy applied in elderly patients with acute cerebral thrombosis and analyze the mechanism of this therapeutic method. DESIGN： 1：1 paired grouping according to gender and controlled observation SETTING： Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University. PARTICIPANTS： Totally 90 elderly patients with acute ischemic stroke who received the treatment in the Cadre Ward and Mental Ward, Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University from March 1996 to June 2004 were recruited. They all met the diagnosis criteria revised by the Fourth Academic Conference of National Cerebrovascular Diseases in 1995 and were diagnosed as acute ischemic stroke by skull CT. They were informed of therapeutic plan and detected items. According to 1：1 paired principle in gender, 90 enrolled patients were assigned into treated group （n=45） and control group （n=45）. There were 39 male and 6 female in the treatment group, and they were aged （76±6）years, ranging from 71 to 84 years, and hospitalized at the 14^th to 76^th hours after onset. There were 39 male and 6 female in the control group, and they were aged （76±6）years , ranging from 70 to 82 years, and hospitalized at the 16^th to 72^th hours after onset. METHODS： Therapeutic method： Patients of treated group received modified hemodilution combined therapy. 200 mL whole blood of patients was exchanged with 500 mL dextran-40 （including 20 mL danshen parenteral solution and 32 mg heparin） at the beginning of therapy; From the 2^nd day, compound huangqi tea bag （Huangqi mainly, including danshen, honghua, chuanxiong, shishao and a little acetyl salicylic acid） was made, twice a day, 1 bag once. At the same time, the above-mentioned dextran-40 liquid of 500 mL was intravenously injected, once a day, 14 days in total; On the 6^th day after therapy, the above-mentioned aseptic autoblood stored in refrigerator at 4℃ was transfused back into the patients following pre-treatment of high-concentration oxygenation and ultraviolet irradiation by light quantum instrument. Patients of control group were intravenously injected of 0.4 g venoruton（Traditional Chinese medicine compound parenteral solution for promoting blood circulation and removing blood stasis ） and 50 g/L glucose of 500 mL, 75 mg acetosal was taken orally, once a day, 14 days in total. ② Measurement and observation of index： Blood coagulation index, change of platelet aggregation rate and change of hemorrheology of patients in two groups were monitored before and after therapy. The level of blood lipid of patients in two groups was measured with American Beckman automatic biochemistry analyzer. Blood flow rate of middle cerebral artery of resting electrocardiogram were measured with American HP SONOS 2500 sonoscope. Neuro-dysfunction score revised in the national conference （1995） was used to evaluate the recovery of neurological function of the patients in two groups at the 3rd, 5^th, 7^th and 14^th days after therapy. ③Therapeutic effect and adverse effect were observed at the same time. MAIN OUTCOME MEASURES ： ① Changes of coagulation index, blood lipid level and hemorheology; ② Blood flow rate of middle cerebral artery and NDS of patients with acute ischemic stroke in two groups; ③Adverse effect of drug. RESULTS： Totally 90 patients were enrolled in the experiment. One patient from treated group died of hyperosmolar nonketotic diabetic coma of complicated diabetes mellitus. One patient from control group died of severe pulmonary infection. The rest 88 patients entered the stage of result analysis. ① Change of coagulation index and platelet aggregation rate： prothrombin time （PT）, activated partial thromboplastin time （APTT） and thrombin time （TT） of patients after therapy were significantly longer than those before therapy in the treated group and those after therapy in control group [After therapy in treated group： （18.4±1.9）, （41.8±2.1）, （19.7±1.7） s, Before therapy in treated group： （13.4±1.3）, （35.8±1.3）, （12.5±0.9） s, After therapy in control group： （16.9±1.5）, （39.1±1.1）, （11.9±2.1） s, P〈 0.05]：Concentration of fibrinogen （Fbg） after therapy was significantly lower than that before therapy in the treated group and that after therapy in control group[After therapy in treated group： （3.4±0.4） g/L; Before therapy in treated group： （4.3±0.7） g/L; After therapy in control group：（4.0±0.6） g/L; P 〈 0.05]. Platelet aggregation rate decreased from （37.92 ±0.85）% before therapy to （26.42±1.01）% after therapy （P 〈 0.01）. ②Change of blood lipid level： Levels of total cholesterol （TC）, triacylglycerol（TG） and low density lipoprotein cholesterol （LDL-C） of patients after therapy were significantly lower than those before therapy in treated group and those after therapy in control group [After therapy in treated group： （5.2±0.9）, （1.9±0.9）, （2.08±1.1） mmol/L, before therapy in treated group： （5.9±1.2）, （2.8±0.9）, （3.94±0.5） mmol/L, After therapy in control group： （6.0±1.1）, （2.6±0.8）, （3.84±0.9） mmol/L, P 〈 0.05]. ③Change of hemorheology index： Hematocrit of patients of treated group was significantly lower after therapy than before therapy [Before therapy： （43.84±4.55）% ;After therapy： （40.48±4.02）%;P 〈 0.05]. Blood flow rate of middle cerebral artery of patients of treated group was significantly lower before therapy than after therapy [（90±1.2）, （97±2.1） cm/s,P〈 0.01]. ⑤NDS of patients in treated group was significantly lower than of control group 14 days after therapy. The total effective rate after therapy was significantly higher in the treated group than in the control group （93%,78%, P 〈 0.05）. ⑥There was no obvious adverse effect. CONCLUSION： Modified hemodilution combined therapy can improve hemorheology, decrease hematocrit, increase blood flow rate of middle cerebral artery, so as to improve the impaired clinical neurological function of elderly patients with acute cerebral thrombosis through anticoagulation and antiplatelet aggregative activity as well as regulating blood lipid.

Future directions for using estrogen receptor agonists in the treatment of acute and chronic spinal cord injury

All synthetic and natural estrogen receptor agonists, in- cluding the most potent physiological molecule estrogen or estradiol （E2）, work typically via activation of nuclear estrogen receptor alpha （ERα） and estrogen receptor beta （ERβ）. Both ERα and ERβ modulate the expression of a variety of genes in the cells. Neurons and glial cells express ERa and ERβ. Many studies so far from our and other laboratories have firmly established the mode of actions that ERα and ERβ agonists are very promising anti-inflammatory and neuroprotective agents in the treatment of neurodegenera- rive diseases and injuries including spinal cord injury （SCI） （Chakrabarti et al., 2014a）.

Changes of biochemical indexes in patients with acute cerebral infarction after treatment with simvastatin

BACKGROUND: At present, it is believed that the important causes of cerebral infarction are the disorders of lipid metabolism and endothelial function, and the outcomes of clinical treatment can be improved by regulating serum lipids and antiinflammation, etc. OBJECTIVE: To observe the effect of simvastatin, inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase, on the levels of serum lipids, serum enzymic indexes and inflammatory metabolic indexes in patients with cerebral infarction. DESIGN: A comparative observation. SETTING: Department of Geriatrics, Longquanshan Hospital of Liuzhou City. PARTICIPANTS: Forty-eight patients with acute cerebral infarction were selected from the Department of Geriatrics of Longquanshan Hospital of Liuzhou from March 2004 to February 2006, including 24 males and 24 females, the mean age was (54±12) years, average disease course was (10.0±4.5) days. They were all accorded with the diagnostic standard for cerebral infarction set by the Fourth National Academic Meeting for Cerebrovascular Disease in 1999, and cerebral hemorrhage was excluded by cranial CT scanning. The 48 patients were randomly divided into control group (n =24) and treatment group (n =24). Informed consents were obtained from all the participants. METHODS: ① All the patients were treated according to the symptoms, besides those in the treatment group were given simvastatin (Harbin Pharm. Group Sanjing Pharmaceutical Shareholding, Co.,Ltd., No. H20010454; Batch number: 20040218; 5 mg/tablet). The initial dosage was 10 mg per day for 4 weeks, and then increased to 30 mg per day for another 4 weeks. ② Before treatment and within 1 week after treatment, the total cholesterol, triglyceride, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), aspartate aminotransferase (AST), creatine kinase and C reactive protein in serum were determined with Beckman-cx7 automatic biochemical analytical apparatus in both groups. ③ The differences of intergroup and intragroup data were compared with the independent-samples t test and paired samples t test. MAIN OUTCOME MEASURES: Changes of total cholesterol, triglyceride, HDL-C, LDL-C, AST, creatine kinase and C reactive protein before and treatment in both groups. RESULTS: All the 48 patients with cerebral infarction were involved in the analysis of results. ① Changes of serum lipids: The levels of serum lipids were close between the two groups before treatment (P > 0.05). After treatment, the HDL-C level in the treatment group was obviously higher than that in the control group and that before treatment [(1.34±0.12), (0.92±0.33), (0.93±0.21) mmol/L, t =7.922, 11.699, P < 0.01], and the levels of total cholesterol, triglyceride and LDL-C were obviously lower than those in the control group and those before treatment (t =2.780-7.591, P < 0.01). ② Changes of serum enzymic indexes and C reactive protein in serum: The levels of enzymes and C reactive protein in serum had no obvious differences between the two groups before treatment (P > 0.05). The levels of AST, creatine kinase and C reactive protein in serum after treatment were obviously lower than those before treatment in both groups (t =7.259-17.996, P < 0.01). The levels of levels of creatine kinase and C reactive protein in serum after treatment in the treatment group were obviously lower than those in the control group [(3.061±0.522) μkat/L, (4.6±3.1) mg/L; (4.348±0.580) μkat/L, (12.3±4.8) mg/L, t =7.910, 6.463, P < 0.01]. CONCLUSION: Compared with common treatment according to symptoms, the additional administration of simvastatin is better for improving the serum lipids, serum enzymic indexes of patients with cerebral infarction at acute period, and benefit for repairing their inflammatory damages.

Impact of statin usage patterns on outcomes after percutaneous coronary in-tervention in acute myocardial infarction：Korea Working Group on Myocar-dial Infarction registry （KorMI） study

Background The benefit of statin use after acute ST-segment elevation myocardial infarction （STEMI） has been well established, however, the influence of the timing of statin administration has not been elucidated. The objective of this study focused on early clinical outcomes after percutaneous coronary intervention （PCI）. Methods This analysis of the Korea Working Group on Myocardial Infarction registry （KorMI） study included 3,584 STEMI patients （mean age, 63 ±13 years;male, 2,684, 74.9%） undergoing PCI from January 2008 to June 2009. Rates of major adverse cardiac events （MACE：all-cause death, recurrent MI, and target lesion revascularization） were compared among patients grouped according to statin therapy timing：I, both during and after hospitalization （n=2,653, 74%）;II, only during hospita-lization （n=309, 8.6%）;III, only after discharge （n=157, 4.4%）;and IV, no statin therapy （n=465, 13%）. Mean follow-up duration was 234 ± 113 days. Results Multivariate factors of statin use during hospitalization included prior statin use, multiple diseased vessels, final thrombolysis in myocardial infarction flow grade III, and low-density lipoprotein cholesterol level. At 6-month follow-up, groups Ⅲ and Ⅳ had the highest MACE rates （2.3%, 3.9%, 5.1%, and 4.9%for groups I-IV, respectively, P=0.004）. After adjusting for confounders, groups Ⅱ-Ⅳ had a higher MACE risk than group Ⅰ [hazard ratio （HR）：3.20, 95%confidence interval （95%CI）：1.31-7.86, P=0.011;HR：3.84, 95%CI：1.47-10.02, P=0.006;and HR：3.17, 95%CI：1.59-6.40, P=0.001;respectively]. Conclusions This study, based on the national registry database, shows early and continuous statin therapy improvs early outcomes of STEMI patients after PCI in real-world clinical prac-tice.

Bleeding risk stratification in an era of aggressive management of acute coronary syndromes

Major bleeding is currently one of the most common non-cardiac complications observed in the treatment of patients with acute coronary syndrome(ACS). Hemorrhagic complications occur with a frequency of 1% to 10% during treatment for ACS. In fact, bleeding events are the most common extrinsic complication associated with ACS therapy. The identification of clinical characteristics and particularities of the antithrombin therapy associated with an increased risk of hemorrhagic complications would make it possible to adopt prevention strategies, especially among those exposed to greater risk. The international societies of cardiology renewed emphasis on bleeding risk stratification in order to decide strategy and therapy for patients with ACS. With this review, we performed an update about the ACS bleeding risk scores most frequently used in daily clinical practice.

AIM: To examine the efficacy and safety of otilonium bromide (OB) in treatment-sensitive functional irritable bowel syndrome (IBS) clinical parameters.

Ischemic bowel disease in 2021

Ischemic bowel disease(ISBODI)includes colon ischemia,acute mesenteric ischemia(AMI)and chronic mesenteric ischemia(CMI).Epidemiologically,colon ischemia is the most common type followed by AMI and CMI.There are various risk factors for the development of ISBODI.Abdominal pain is the common presenting symptom of each type.High clinical suspicion is essential in ordering appropriate tests.Imaging studies and colonoscopy with biopsy are the main diagnostic tests.Treatment varies from conservative measures to surgical resection and revascularization.Involvement of multidisciplinary team is essential in managing ISBODI.Although open surgery with revascularization plays an important role,recently there is an increasing interest in percutaneous endovascular treatment.

Association of ALOX5AP with ischemic stroke in eastern Chinese

BACKGROUND：5-1ipoxygenase protein （ALOX5AP） has been recognized as a susceptibility gene for stroke and coronary artery diseases. The present study was to explore the role of this gene in the eastern Chinese patients with ischemic stroke.METHODS： Using a case-control design, we studied 658 patients with ischemic stroke and 704 unrelated population-based controls who were age- and sex-matched. The 658 patients were classified by the Trial of Org 10172 in Acute Stroke Treatment （TOAST）. Two single-nucleotide polymorphisms （SNPs） covering ALOX5AP were genotyped. RESULTS： The genotype frequencies of TG of the SNPs rs17222919 located in the promoter of the ALOX5AP gene were significantly higher in patients with ischemic stroke than in controls （OR＊=1.34, 95%C1＊=1.02-1.75）, especially in patients with ischemic stroke caused by small-artery occlusion （SAO） （OR＊=1.40, 95%C1＊=1.02-1.93）. Meanwhile, the genotype frequencies of TG and TG/ GG were higher in female patients than in the controls. After specification, the genotype frequencies of TG and TG/GG were higher in the patients than in controls with hypertension. The genotype frequencies of AG and AG/GG of the SNPs rs9579646 located in the intron of the ALOX5AP gene were higher in the controls than in the patients. After specification, the genotype frequencies of TG were higher in the controls than patients without hypertension. CONCLUSIONS： The present study suggests that sequence variants in the ALOX5AP gene are significantly associated with ischemic stroke.

MicroRNA-122-functionalized DNA tetrahedron stimulate hepatic differentiation of human mesenchymal stem cells for acute liver failure therapy

As the most abundant liver-specific microRNA, microRNA-122 (miR122) played a crucial role in the differentiation of stem cells into hepatocytes. However, highly efficient miR122 delivery still confronts challenges including poor cellular uptake and easy biodegradation. Herein, we for the first time demonstrated that the tetrahedral DNA (TDN) nanoplatform had great potential in inducing the differentiation of human mesenchymal stem cells (hMSCs) into functional hepatocyte-like cells (HLCs) by transferring the liver-specific miR122 to hMSCs efficiently without any extrinsic factors. As compared with miR122, miR122-functionalized TDN (TDN-miR122) could significantly up-regulate the protein expression levels of mature hepatocyte markers and hepatocyte-specific marker genes in hMSCs, indicating that TDN-miR122 could particularly activate the hepatocyte-specific properties of hMSCs for developing cell-based therapies in vitro. The transcriptomic analysis further indicated the potential mechanism that TDN-miR122 assisted hMSCs differentiated into functional HLCs. The TDN-miR122-hMSCs exhibited hepatic cell morphology phenotype, significantly up-regulated specific hepatocyte genes and hepatic biofunctions in comparison with the undifferentiated MSCs. Preclinical in vivo transplantation appeared that TDN-miR122-hMSCs in combination with or without TDN could efficiently rescue acute liver failure injury through hepatocyte function supplement, anti-apoptosis, cellular proliferation promotion, and anti-inflammatory. Collectively, our findings may provide a new and facile approach for hepatic differentiation of hMSCs for acute liver failure therapy. Further large animal model explorations are needed to study their potential in clinical translation in the future.

Experiences on the Integrative Medical Diagnosis and Treatment of Acute Kidney Injury

The definition of acute renal failure（ARF） has not gotten common understanding yet in a long time,which leads to the difficulty in comparing the outcomes of some different studies,and has impacted the advance of diagnosis and treatment on the illness to certain extents. Most of the scholars hold that the attention paid to the early diagnosis and intervention of ARF was insufficient in recent years. Lots of clinical researchers indicated that even a slight impairment of renal function could result in the increasing of the morbidity and mortality of ARF.

Effect of Wulong Dan on Treatment of Acute Cerebral Infarction and Change of Hormones in Hypothalamus-Pituitary-Thyroid Axis

Objective:To explore the effect of Wulong Dan (WLD) on treatment of acute cerebral infarction and change of hormones in hypothalamus-pituitary-thyroid axis. Methods:Thirty five cases of the treated group treated with WLD by taken orally and 31 cases of the control group treated with nimoton taken orally. And dextran was given intravenously to both groups. Blood level of triiodothyronine (T3), free triiodothyronine (FT3), thyroxine (T4), free throxine (FT4) and thyroid stimulating hormone (TSH) of all patients were determined before and after treatment by radioimmunoassay. Results: After 4 weeks of treatment, there were significant difference between the treated group and the control group in cure rate, markedly effective rate,cure score and disappearance of clinical symptoms (P < 0. 01 ). The levels of T3, FT3,TSH of all patients were lower than those of the normal control before treatment. After treatment with WLD and dextran, the abovementioned indexes turned to normal. Conclusions: WLD has a significant effect on patients with cerebral infarction on the basis of improved microcirculation induced by dextran. It also has regulatory effect on the hypothalamuspituitary-thyroid axis disorder so as to be helpful in maintaining the homeostasis.

Mechanisms of multiple organ damages in acute necrotizing pancreatitis

Abstract:Objective To determine the role of systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS), and evaluate the progress from SIRS to MODS and the therapeutic strategies for acute necrotizing pancreatitis (ANP).Methods Rat ANP models were made by retrograde injection of 3.5% sodium taurocholate 2.5?ml/kg into the pancreatic duct. Serum interleukin-8 (IL-8), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNFα), amylase, endotoxin, and albumin were examined. The morphology and pathology of the pancreas, liver, lung, kidney and heart after ANP were observed. Finally, TNFα mRNA in the liver, lung, kidney and heart after ANP were observed by reverse transcriptase-polymerase chain reactions, and the efficiency of somatostatin and growth hormone were also observed in this experiment.Results ANP led to remarkable elevation of the inflammatory mediators which were positively correlated with the development of ANP and MODS. Somatostatin and growth hormone inhibited inflammatory mediators and TNFα mRNA overexpressions, reduced the risk of MODS, corrected hypoalbuminemia, reversed negative nitrogen balance, and controlled the reduction of cell groups with functions and reasonably intervened SIRS caused by ANP.Conclusion TNFα mRNA plays an important role in ANP progression. The amelioration of ANP by combination treatment with somatostatin and growth hormone leads to the reduction of complications and marked increase in survival.

A hospital outbreak of severe acute respiratory syndrome in Guangzhou,China

Objective To describe a hospital outbreak of severe acute respiratory syndrome (SARS) and summarize its clinical features and therapeutic approaches.Methods The outbreak started with a SARS patient from the community, and a total of 96 people (76 women and 20 men, mean age (29. 5±10. 3) years, 93. 8% of whom were health care workers) who had exposure to this source patient became infected in a short time. Clinical data in this cohort were collected prospectively as they were identified.Results (1) The incubation period ranged from 1 to 20 (mean: 5. 9±3. 5) days. The duration of hospitalization was (17. 2±8. 0) days. (2) The initial temperature was (38. 3±0. 6)℃, while the highest was (39. 2 ±0. 6)℃( P<0. 001), with fever duration of (9. 0±4. 2) days. (3) Other most common symptoms included fatigue (93. 8%), cough (85. 4%), mild sputum production (66. 7%), chills (55.2%), headache (39.6%), general malaise (35.4%) and myalgia (21.9%). (4) The radiographic changes were predominantly bilateral in the middle or lower lung zones. The number of affected lung fields was 1. 2±0. 8 on presentation, which increased to 2. 9 ?1. 4 after admission (P<0. 001). The interval from the beginning of fever to the onset of abnormal chest radiographs was (3. 5±2. 3) days, which increased in size, extent, and severity to the maximum (6. 7±3. 5) days later. The time before the lung opacities were basically absorbed was (14.9±7.8) days. (5) Leukopenia was observed in 67. 7% of this cohort. The time between the onset of fever and leukopenia was (4. 4±2. 3) days, with the lowest white blood cell count of (2. 80±0. 72)×10~9/L (6) The lowest arterial oxygen saturation was (94.8±3.1 )% with supplementary oxygen. (7) Antibiotical therapies included tetracyclines ( 91. 0%), aminoglycosides ( 83. 3%), quinolones (79. 2%); 18. 8% of the patients received a combination of tetracyclines and aminoglycosides, while 11. 5% received a combination of tetracyclines and quinolones, and 63. 5% received a combination of tetracyclines, aminoglycosides and quinolones. Vancomycin was used in 13. 5% of the patients. (8) 68. 8% of the patients were treated with methylprednisolones for a mean interval of (4. 9±2. 4) days. The initial dose was (67. 3±28. 2) mg/d and the maximal dose was (82. 4 ±30. 5) mg/d. (9) Human y-globulin, interferon-α, antiviral drugs (oral ribavirin or oseltamivir) were used respectively in 68.6%, 46.9% and 92.7% of the patients. (10) Ninety-five patients (99.0%) had a complete clinical recovery, and only 1 patient (1.0%) died. Conclusions SARS appears to be quickly infectious and potentially lethal among health care workers, characterized by acute onset and rapid progression, and mostly bilateral lung involvement on chest radiographs. Proper administration of glucocorticosteroids seems to be of some benefits. Antibiotics, human y-globulin, interferon-α, and antiviral drugs, although empirically, might be useful to shorten the clinical course.
