OBJECTIVE:To observe the efficacy and safety of atorvastatin in the treatment of hypertension with unstable angi-na. METHODS:80 patients with hypertension with unstable angina were randomly divided into control group and treatment group. All patients were given anti-platelet aggregation and other conventional treatment;based on it,control group was orally treated with Amlodipine besylate tablet 5 mg,once a day+Metoprolol tartrate controlled-release tablet 25 mg,twice a day+Isosorbide dini-trate injection 10 ml by intravenous infusion,twice a day;treatment group was additionally treated with Atorvastatin calcium tablet 20 mg,orally,qd. 3 months was a treatment course,and it lasted 6 courses. Clinical efficacy,and systolic blood pressure,diastol-ic blood pressure,angina frequency and duration,changes of TC,TG,LDL,HDL levels before and after treatment and adverse reac-tions in 2 groups were observed. RESULTS:Total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,systolic blood pressure and diastolic blood pressure in 2 groups were significantly lower or shorter than before,the difference was statistically significant(P<0.05),however,there was no signifi-cant difference between 2 groups(P>0.05);angina frequency and duration were significantly lower than before,and treatment group was lower than control group,TC,TG and LDL in treatment group were significantly lower than before and control group, HDL was higher than before and control group,the differences were statistically significant(P<0.05),there was no significant dif-ference between before and after treatment in control group(P>0.05). There was no significant difference in the adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on the conventional treatment, atorvastatin can effectively reduce the long-term angina frequency and duration of patients with hypertension with unstable angina,improve the ischemia myocardial and reduce the lipid levels with good safety.

To investigate the effect and mechanism of intravascular brachytherapy with 192 Ir on expression of type I collagen after angioplasty. Restenosis model of domestic miniswine was employed.After angioplasty, the iliac arteries were randomized to brachytherapy group ( n =6) , which were treated with 20 25Gy of 192 Ir, and control group ( n =18). The target vessels were harvested at the 12 th week and the 24 th week after angioplasty. Immunohistochemistry and in situ hybridization were used to detect proteins of type I collagen, metalloproteinase 1 (MMP 1) and its tissue inhibitor (TIMP 1), and mRNA expression of type I collagen. The results showed that the protein and mRNA of type I collagen, and the ratios of TIMP 1/MMP 1 were lower in brachytherapy group than in control group. The peak of mRNA expression of type I collagen was at the 24 th week in control group and at the 12 th week in brachytherapy group, respectively. It suggested that intravascular brachytherapy with 192 Ir affects the metabolism of extracellular matrix by inhibiting the synthesis of type I collagen and regulating the activities of MMP 1 and TIMP 1.

Objective To study the immuno-protective effect against Schistosoma japonicum challenge of the positive monoclonal phages which were screened from the 12 mers-phage random peptide library by the new model rabbit serum. Methods The new model was established by injecting the Schistosoma japonicum infection rabbits with inhibitor of phenol oxidose. Positive clones immunoscreened with the new model rabbit sera were absorbed by SEA immune rabbit sera, and 14 clones selected randomly from them were compared and their antigenic ability was identified by ELISA. The two best positive monoclonal phages (No.8, No.13) recognized by the new model rabbit sera were selected to immunize Kunming mice by subcutaneously injecting 1?10~15 pfu positive phages at 0, 2nd, 4th week respectively. After 4 weeks of the last immunity,each mouse was challenged with 40?1 S.japonicum cercariae. All mice were sacrificed after 42 days and the reduction rates of adult worms and the liver eggs were investigated. Results The positive phage clones after immune absorption were weakly recognized by the SEA immune rabbit sera. The 14 monoclonal phages were recognized by the rabbit sera of the new model and the normal model. Especially No.8, No.13 were strongly recognized by the rabbit sera of the new model,while weakly recognized by the SEA immune rabbit sera. The reduction rates of adult worms and liver eggs induced by the monoclonal phage No.13, the monoclonal phage No.8 and the original peptide library were 35.81% and 63.32%, 32.09% and 52.02%, 14.90% and 30.64%, respectively. Conclusion Most clones of simulated epitopes of SEA can be removed by absorbing positive clones with SEA immune rabbit serum .The 14 monoclonal phages from the new model contain the simulated S.japonicum epitope. The two monoclonal phages have higher reduction rates of adult worms and eggs than original 12 mers-phage random peptide library and the positive polyclonal phages.[

Objective To investigate the relationship between the serum homocysteine(Hcy) level and heart rate variability in elderly patients with metabolic syndrome.Methods Retrospective analysis of 162 elderly patients with metabolic syndrome aged 60 and above was conducted in our hospital from January 2013 to August 2016.And the level of serum homocysteine and other biochemical indicators were measured.The 162 cases were divided into three groups of 42 cases in Hcy normal group(Hcy,5-15 μmol/L),70 cases in Hcy mildly high group(Hcy,16-30 μmol/L),50 cases in Hcy moderately high group (Hcy,31 ～ 100 μmol/L).Simultaneously 24-hour rhythm in ambulatory heart rate variability spectrum was used to detect HRV.And the relationship between heart rate variability(HRV) and Hcy levels were analyzed.Results Normal RR interval standand deviation (SDNN),5 min mean heart rate standard deviation (SDANN),Edinburg index (PNN50),root mean square value of adjacent RR interval difference(RMMSD)were all lower in Hcy mildly high group and Hcy moderately high group than in the Hcy normal group (P＜0.05).Low-frequency(LF) and highfrequency(HF)were lower in Hcy mildly high group and Hcy moderately high group than in the Hcy normal group(P ＜ 0.05).Sympathetic-vagal balance indicators (LF/HF) were higher in Hcy mildly high group and Hcy moderately high group than in the Hcy normal group (P＜ 0.05).The HRV indexes were lower in Hcy high groups than in the Hcy normal group.Hcy was negatively correlated with SDANN,RMSSD,LF,HF,and LF/HF at night(r=-0.578、-0.651、-0.531、-0.662、-0.729,all P ＜ 0.01).Conclusions The elevated homocysteine level and metabolic syndromecombined with decreased HRV in the elderly patients suggest that cardiac autonomic nervous system might be injuried.Enhancing the detection of HRV and homocysteine level in elderly patients with MS is clinically useful for early detection of autonomic neuropathy.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Objective: To study the properties and behavior of dynamics in the tactical reserve models of medicine supplies. Methods: A tactical reserve model of medicine supplies was established with methods of systematic dynamics, and the behaviors of the system was simulated by computer program when parameters changed. Results:The quantity of initial reserve did not obviously effect the average inventory and amount of goods in short. However, objective reserve, rate of supply and rate of deliver evidently affected average inventory and amount of goods in short. Conclusion: The system efficiency is not influenced if the rate of supply is guaranteed.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Objective To assess the efficiency and safety of mycophenolate mofetil (MMF) in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO). Methods Twenty-seven patients with MS or NMO were selected, and the patients were divided into 2 groups:MMF group (MMF combined with glucocorticoid treatment group, 10 cases) and glucocorticoid group (only glucocorticoid treatment group, 17 cases). There were 5 cases with MS and 5 cases with NMO in MMF group. There were 13 cases with MS and 4 cases with NMO in glucocorticoid group. The therapeutic efficacy 6 months after treatment, expanded disability status scale (EDSS) before treatment and 6 months after treatment, and annualized relapse rate (ARR) were compared; and the safety was observed. Results There was no statistical difference in efficacy rate 6 months after treatment between MMF group and glucocorticoid group: 9/10 vs. 11/17, P>0.05. The EDSS scores 6 months after treatment in MMF group and glucocorticoid group were significantly lower than those before treatment: (2.41 ± 2.05) scores vs. (3.40 ± 2.05) scores and (1.17 ± 0.92) scores vs. (2.38 ± 1.28) scores, and there were statistical differences (P<0.05), particularly for the patients with MS. The ARR 6 months after treatment in MMF group was significantly lower than that before treatment: 0 time/year vs. 0.75 times/year, and there was statistical difference (P<0.05). The difference of ARR before and after treatment in MMF group was significantly higher than that in glucocorticoid group: 0.75 times/year vs.- 0.46 times/year, and there was statistical difference (P<0.01), particularly for the patients with MS. Only 1 female patient had myalgia when taking higher dosage of MMF, and the symptom tended to relieve after the dosage was reduced. Conclusions MMF is effective in the treatment of MS and NMO. MS can improve the neurological function and reduce the recurrence of the disease;and the safety is high.

Objective The aim of this study is to evaluate the safety and efficacy of partial pancreatectomy as part of primary cytoreductive surgery in advanced epithelial ovarian cancer (EOC). Methods A total of 8 patients were recruited in this study who underwent partial pancreatectomy during the primary cytoreductive surgeries for advanced EOC in Fudan University Shanghai Cancer Center from April 2009 to July 2015. Their clinicopathological characteristics, diameter of metastatic tumors, the scope of cytoreductive surgeries, residual diseases after cytoreductive surgeries, postoperative complications and survival situation were retrospective analyzed. Results (1) Clinicopathological characteristics:the median age of these patients was 58 years old(range: 39-63 years old). The median value of preoperative serum CA125 was 1 688 kU/L(range: 119-5 000 kU/L). The median diameter of metastatic tumors involved in pancreatic body or tail was 4.5 cm (range:3-10 cm). All the tumors from the 8 patients were confirmed to be high-grade serous carcinoma. Four patients were staged as International Federation of Gynecology and Obstetrics (FIGO)Ⅳ, and the other 4 patients were staged as FIGOⅢc. (2) Tumor metastases and the scope of cytoreductive surgeries:all of these 8 patients had widely disseminated ovarian cancer, with involvement of upper abdominal, middle abdominal and pelvic cavity. Each patient underwent extensive intra-abdominal cytoreductive surgeries, including hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic periton-ectomy, splenectomy, partial pancreatectomy. Each patient had cytoreductive surgeries of 9.6 different sites on average. Of all 8 patients who underwent partial pancreatectomy, 7 patients had pancreatic tails removed;the other 1 patient had pancreatic body and tail removed. The median volume of blood loss during surgery was 1 350 ml(range:300-3 500 ml), blood transfusion was performed in 7 patients with the median volume of 1 150 ml (range: 500-1 800 ml). (3) Residual diseases after cytoreductive surgeries: optimal cytoreduction was achieved in all patients, with microscopic residual disease in 3 patients, residual tumors diameter < 0.5 cm in 3 patients, and residual tumors diameter between 0.5 and 1 cm in 2 patients. (4) Postoperative complications: 4 patients suffered from complications including pancreatic leakage (2/8), intraperitoneal hemorrhage (1/8) and pancreatic pseudocyst accompanied by infection (1/8). These complications were treated successfully by conservative managements. (5) Survival situation: during the median follow-up duration of 17 months (ranged from 2 to 46 months), 5 patients were still alive until the end of follow-up, including 4 cases under treatment and 1 case survived 29 months without relapse after treatment. Three patients were respectively died in 5, 20 and 46 months after surgery. Conclusion There is a higher risk of postoperative complications of pancreas resection as part of primary cytoreductive surgery in advanced epithelial ovarian cancer, but the resection of pancreatic metastases and part of the pancreas is feasible and necessary.
