Objective To investigate the value of serum pentraxins-3 (PTX-3) together with triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) as predictor risk factors of future acute coronary syndrome(ACS). Methods One hundred and seventy-one cases of selective coronary angiography from July 2008 to December 2009 were collected and analyzed. According to the situation on admission and coronary angiography, patients were divided into three groups: normal control group (25 cases), stable angina pectoris (SAP) group (23 cases) and ACS group (123 cases). Fasting venous blood was extracted for measuring serum PTX-3 and lipids (TG, HDL-C) in the next morning, and the statistical significanc was analyzed. Results The level of serum PTX-3 and the ratio of TG to HDL-C in ACS group [(6.39 ± 3.01)μ g/L, 2.38 ± 2.00] were significantly higher than those in SAP group[(3.87 ± 2.05 ) μ g/L, 1.70 ± 1.01] and normal control group [(2.90 ± 1.94)μg/L,0.95 ±0.35] (P ＜0.01 or ＜0.05). Conclusion Increased serum PTX-3 levels and ratio of TG to HDL-C in patients are closely related with ACS, both of which increase the accuracy of early diagnosis of ACS.

Objective To evaluate the safety of a self-made vena cava stent-filter(VCSF)for prevention of pulmonary embolism.Methods Fusiform unmbrella-like vena cava filter was made of Nitinol wires and stainless steel metal pole,and then ten mongrel dogs were implanted with these self-made filters and divided into 5 groups according to the different periods(2,3,4,5 and 6 w) of filter placement,with 2 dogs in each group.After the VCSFs were placed in inferior vena cava via the right femoral vein approach,the dogs in each group were bred for 2-6 weeks,respectively.The blood flow of inferior vena cava and the position of the filters were inspected by inferior vena-cavography according to the indwelling periods.Finally the metal pole was retrieved via the femoral vein,leaving the VCSF as permanent venous stent.The feasibility of retrieval and the free state of filter net with the adhering vascular wall were evaluated.Laparotomies were performed to remove the inferior vena cava from the animals for gross and electron microscopic examinations of the inferior vena cava intimal changes of the involved segment.Results All 10 VCSFs were placed at the right positions of the dogs successfully.Angiography showed patent inferior vena cava without filter thrombosis at 2-6 weeks.There were no tilting and migration of the filter and all the metal poles were successfully retrieved.The superior and inferior extremities of filter nets could be set free with all the filters turning into venous stents.Postmortem displayed retroperitoneal hemorrhage and caval thrombosis.The barbs of the filters penetrated over the caval adventitial coat.Under electron microscope,a thin layer of neointima already covered the braiding net of VCSFs at 2 weeks after the deployment.The tunica intima became slightly thick at 3-4 weeks and with moderate proliferation at 5-6 weeks.Conclusions The self-made vena cava stent-filter possesses rather long indwelling period according to the necessity of treatment with simultaneously keeping patent caval flow,stability of the position and easy for displacement and retrieval.

Objective To evaluate the effect of propofol on mitochondrial fission in a rat hippocampal neuron model of hypoxia/reoxygenation (H/R) injury.Methods Primarily cultured hippocampal neurons of neonatal Sprague-Dawley rats were randomly divided into 4 groups (n =42 each) using a random number table:control group (group C);vehicle group (group V);H/R group;H/R+propofol group (group H/R+P).In group V,H/R was not produced,the vehicle dimethyl sulfoxide with the final concentration of 0.01％ was added,and the cells were then incubated for 6 h.In group H/R,the hippocampal neurons were subjected to oxygen-glucose deprivation for 6 h followed by 20 h reoxygenation.In group H/R+P,propofol with the final concentration of 1 μmol/L was added at 6 h of hypoxia.At 20 h of reoxygenation,the cell apoptosis (using flow cytometry),Ca2+ concentrations in cytoplasm (with the laser scanning confocal microscope),calcineurin (CaN) activities (by enzyme-linked immunosorbent assay),and expression of mitochondrial fission proteins dynamin-related protein 1 (Drp1) and fission 1 (Fis1),and apoptosis-related proteins cytochrome c (Cyt c) and apoptosis-inducing factor (AIF) (by Western blot) were measured.The apoptotic rate was calculated.Results Compared with group C,the apoptotic rate,Ca2+concentrations,CaN activities,and expression of Drp1,Fis1,Cyt c and AIF were significantly increased in H/R and H/R+P groups (P＜0.05),and no significant changes were found in the parameters mentioned a2+.bove in group V (P＞0.05).Compared with group H/R,the apoptotic rate,Ca+ concentrations,CaN activities,and expression of Drp1,Fis1,Cyt c and AIF were significantly decreased in group H/R+P (P＜0.05).Conclusion Propofol can reduce the H/R injury to rat hippocampal neurons through inhibiting mitochondrial fission.

ObjectiveTo evaluate the efficacy and clinical safety of sodium glycididazole (CMNa)in thoracic esophageal squamous carcinoma.Methods From June 1,2008 to October 13,2009,66pathologically proved thoracic esophageal squamous carcinoma (stage Ⅱa-Ⅲ,stage Ⅳ with metastases only in supraclavicular lymph nodes,by AJCC 6th ed) were randomized into radiotherapy plus CMNa (A) or radiotherapy plus placebo (B) group.Radiotherapy was given by conventional schedule:1.8-2.0 Gy per fraction,5 times per week to a total dose of 66 Gy/6.6-7.2w.CMNa was given intravenously 800 mg/m2 3 times a week in solution of 100 ml saline within 30 minutes.Radiotherapy was started 30-60 minutes after completion of infusion.Patients of Group B received placebo in saline solution.A total of 66 patients were enrolled ( Group A:32 ; Group B:34 ),and four patients were unanalyzable,remaining 31 patients in each Group.Baseline factors were balanced.ResultsFollow-up rate was 97％.Group A vs.Group B:the overall response rate was 93.5％ vs.67.7％ ( x2 =6.61,P =0.01 ),2-year overall survival was 39.9％ vs.29.9％ ( x2 =0.62,P =0.433 ),2-year cancer specific survival was 43.1％ vs.26.8％ ( x2 =0.30,P =0.878),and 2-year progression-free survival was 30.1％ vs.27.9％ ( x2 =0.02,P =0.586).No severe side effects observed.All patients tolerated CMNa infusion well.Conclusions CMNa is tolerable and effective as a hypoxic radiosensitizer,and its combination with radiotherapy can improve short term effect.However,survival is not improved within our follow-up period.

Objective:To evaluate the efficacy of Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization in the treatment of tubal obstructive infertility of liver depression and qi stagnation type.Methods:A total of 60 patients with tubal obstructive infertility of liver depression and qi stagnation type who met the inclusion criteria were selected, between August 2018 and June 2020, and they were divided into the observation group with 31 cases and the control group with 29 cases, according to the random number table method. The control group was treated with hysteroscopic recanalization, while the observation group was given Chaichuan Tongren Mixture on the basis of the control group. Both groups were treated for 4 months and followed up for 12 months. TCM syndromes were scored before and after treatment, and prostaglandin E 2 (PGE 2) was detected by fully automatic biochemical analyzer and levels of TNF-α, CRP and IL-6 were measured by ELISA. The tubal patency of patients after treatment was observed, the pregnancy status was recorded after the end of follow-up and the clinical efficacy was evaluated. Results:The total effective rate was 96.77% in the observation group and that in the control group was 75.86% ( χ2=4.01, P<0.01). The scores of breast distending pain, irregular menstruation, dark purple menstrual flow and lumbosacral pain in the observation group after treatment were significantly lower than those in the control group ( t values were 17.69, 21.67, 20.89, 14.67, 18.20, respectively, all Ps<0.001). After treatment, the levels of serum PGE 2, TNF-α, CRP, and IL-6 were significantly lower in the observation group than those in the control group [(65.31±6.73) ng/L vs. (87.10±8.85) ng/L, t=10.78; (6.90±0.71) ng/L vs. (11.35±1.23) ng/L, t=17.30; (2.47±0.25) mg/L vs. (5.10±0.52) mg/L, t=25.23; (12.38±1.26) ng/L vs. (30.16±3.15) ng/L, t=29.05] ( P<0.01). After treatment, there was statistical significance in the total effective rate of tubal patency of 96.8% (30/31) in the observation group compared to 79.3% (23/29) in the control group ( χ2=4.43, P<0.01). At the end of follow-up, the pregnancy rate was 71.0% (22/31) in the observation group and 44.8% (13/29) in the control group, and the difference was statistically significant ( χ2=4.21, P<0.01). Conclusion:The Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization can reduce the levels of inflammatory mediators and increase the pregnancy rate of patients with tubal obstructive infertility of liver depression and qi stagnation type.

BACKGROUND:Delayed graft function (DGF) occurs frequently in kidney transplants from donation after cardiac death if creatinine level is high in kidney recipients. OBJECTIVE:To analyze the clinical effects of renal transplantation with kidneys from donors dying of cardiac death in organophosphate poisoning. METHODS:Data were col ected from kidney transplants from two donors dying of cardiac death in organophosphate poisoning. After some donor maintenance, donor organ were obtained and perfused with impulse type machine. Recipients were treated with intervention of immunity induction, anti-rejection drugs and infection prevention drugs during and after renal transplantation. Pathological data of donor kidney zero needle biopsy, DGF after kidney transplantation, complication rate (such as acute rejection), renal al ograft recovery situation, the survival rate of recipients and kidney transplants were col ected and analyzed. RESULTS AND CONCLUSION:Needle biopsy results from four donor kidneys showed that glomerular morphology was normal, but there were edema and degeneration in kidney tubules in some degree. Donor DGF rate was 75%(3/4), acute rejection rate was 0%(0/4), perioperative period donor kidney and recipient survival rate were 100%(4/4). Al recipients showed a good result of transplanted kidney, their creatinine and urea nitrogen were at low level, and had no proteinuria. One recipient died of severe pulmonary infection 4 months after surgery. For some organophosphate poisoning donors dying of cardiac death, donor kidney quality can be improved by suitable donor maintenance and high-quality donor kidney preservation using machine perfusion. Kidney transplants from donors dying of cardiac death in organophosphate poisoning who receive the maintenance of organ function may be a promising candidate for renal transplantation due to a severe lack of kidney donor sources.

Objective To summarize the short-term results of simultaneous pancreas-kidney transplantation (SPK) at a single center in China.Methods SPK was performed on 12 consecutive patients from Jan.2010 to July 2014.All patients had long-standing insulin-dependent diabetes mellitus (IDDM) and subsequent renal failure.Bladder drainage (BD) of exocrine secretion was used in the 10 cases and enteric drainage (ED) in 2 patients.The patients were treated with quadruple therapy,which included ATG or anti-CD25 monoclonal antibody induction therapy,prednisone,tacrolimus and mycophenolat-mofetil (MMF).Results The SPK was performed successfully in 10 cases.One patient accepted re-pancreas transplantation due to necrotizing pancreatitis.One patient suffered hemorrhage of bladder,accepted 3 times of embolization therapy and died due to lung infection.Ten patients achieved excellent renal function and euglycemia,and no further insulin treatment was given in 9.5 ± 4.2 days posttransplant.Fasting plasma glucose returned to normal in 14.2 ± 5.1 days.Serum creatinine returned to normal in 10.4 ± 6.5 days.The mean hospital stay was 21.4 ± 7.3 days.One biopsy-proven renal rejection episodes occurred in 14 days postoperation.Main complications included wound infections on the side of pancreatic graft,lymphorrhagia,tacrolimus toxicity and urinary tract infection.Conclusion SPK is an effective therapy of ESRD.Donated graft protection system foundation,refinement and individualized treatment posttransplantion may be the key factors for successful SPK.

Objective: To evaluate the life quality of the patients with oral cancer. Methods: A questionnaire survey was conducted on 200 patients with oral cancer who met the inclusion criteria by the Chinese version of the University of Washington Quality of Life Questionnaire (UW-QOL, V4. 0) . The data were statistically analyzed by SPSS 20. 0. Results: A total of 200 questionnaires were issued and 145 valid questionnaires (72. 50％) were returned. The scores of somatic function domain and social emotional health domain were 60. 29 ± 15. 62 and 46. 65 ± 23. 21 respectively (P ＜ 0. 05) . Physical health scores and social emotional health scores were positively correlated (r = 0. 584) . Conclusion: Oral cancer patients have poor social and psychological status. Necessary psychological intervention and clinical intervention are of great significance to improve the life quality of the patients. Strengthening of social support can improve their physical health of the patients.

Objective:To evaluate the effect of invasive arterial blood pressure (IBP) monitoring on the prognosis of patients with sepsis.Methods:Patients with sepsis from the MIMIC-Ⅳ database were collected and divided into IBP and non-invasive blood pressure monitoring (NIBP) groups according to whether IBP monitoring was performed. Baseline variables that were considered clinically relevant or showed a univariate relationship with the outcome were entered into a multivariate logistic regression model as covariates.Propensity score matching(PSM) and inverse probability of treatment weighing(IPTW) were used to adjust confounders to ensure the robustness of findings.Subgroup analysis were conducted to evaluate the effect of differences in IBP onset and duration on outcome.Results:The 28-day mortality is lower in IBP group compared with NIBP group( OR=0.54, 95% CI 0.46-0.62, P<0.001), the conclusion maintain robust after PSM and IPTW.Then we conducted a series of logistic regression regarding to different initial IBP time(<24 h,24 h-48 h,>48 h) and the initial IBP time within 24 h showed the same results compared to primary outcoms( OR=0.42, 95% CI: 0.36-0.49, P<0.001). IBP duration varied (≤1day, ≤2days, ≤3days, ≤4days, >4days) all showed a statistically significant association with decreased 28-day mortality in the IBP group. Conclusions:IBP is associated with decreased 28-day mortality in patients with sepsis, and the optimal time of IBP is within 24 hours.
