Objective To observe the effect of Wenxin granule combined with Paroxetine in the treatment of the elderly patients with depression after fracture.Methods 80 patients with depression after fracture were randomly divided into a control group and a study group(n=40 cases,per group),and both groups were treated with the conventional treatment. On this basis, the control group was treated with Paroxetine,while the study group was treated with Wenxin granule combined with Paroxetine. The HAMD score and HAMA score were detected in the patients before the treatment and 4 and 8 weeks after the treatment separately.Results Before the treatment,there was no statistical significance in HAMD and HAMA score(t=0.512, 0.520,P>0.05). After treated for 4 and 8 weeks,compare with the control group,both HAMD score(t=1.828, 2.259,P<0.05) and HAMA score(t=1.819, 2.261,P<0.05) were decreased in the study group. After treatment for 4 and 8 weeks, compare with the control group, the total efficiency showed in the HAMD reduction rate of the study group was better(χ2=3.203, 4.370,P<0.05).Conclusions Wenxin granule combined with Paroxetine can significantly decrease HAMD and HAMA score,obviously improve the depression symptoms in the elderly patients with depression after fracture.

Effects of endomorphin-1 (EM-1) and endomorphin-2 (EM-2) on synaptic transmission were investigated on neurons in substantia gelatinosa (SG) of the spinal dorsal horn by whole-cell voltage clamp recording. Both EM-1 (1 μmol/L) and EM-2 (1 μmol/L)remarkably reduced the frequency but not the amplitude of miniature excitatory postsynaptic currents (mEPSCs) and miniature inhibitory postsynaptic currents (mIPSCs). These effects were antagonized by 3-funaltrexamine ( β-FNA, 10 μmol/L), a selective μ-opioid receptor antagonist. Noticeably, EM-1 showed higher potency in decreasing the frequency of mEPSCs and mIPSCs than that of EM-2. These results indicate that EMs suppress both excitatory and inhibitory synaptic transmission by activating presynaptic μ-opioid receptors in the SG and EM-1, compared with EM-2, might be a more potent endogenous analgesic at the spinal cord level.

Objective:To explore the effective diagnosis method and the clinical effect of laparoscopic technique for atypical CE1 hepatic cystic echinococcosis.Methods:The clinical data of 17 patients with atypical liver cystic echinococcosis from June 2018 to June 2019 in the People's Hospital of Xinjiang Uygur Autonomous Region were analyzed retrospectively, including 11 males and 6 females, (46.0±21.6) years old, all patients with a history of exposure in animal husbandry area. Preoperative hydatid immunity test, abdominal ultrasound and abdominal CT examination were completed, and laparoscopic surgery was performed. Postoperative follow-up was conducted by outpatient review and telephone, and the follow-up period was up to June 2020. The diagnosis, operation and recurrence of hydatid disease by different examination methods were analyzed.Results:Preoperative serum immunological examination of 17 patients showed that 11 were positive and 6 were negative for hepatic echinococcosis. The results of abdominal CT showed that 17 cases were hepatic cyst. Conventional color doppler ultrasound showed that 14 patients were hepatic cyst, 3 patients showed cystic space occupying, and cystic hydatidosis was not excluded; 9 patients observed double track sign or local thickening of cystic wall at the top of hepatic cystic lesions after replacement of high-frequency probe, which was diagnosed as hepatic cystic echinococcosis(CE1) , 8 patients as hepatic cyst. All 17 patients underwent laparoscopic operation, during which they were definitely diagnosed as hepatic cystic echinococcosis (CE1). During the operation, there was no conversion to laparotomy. The operation time was (125.0±54.5) min, the intraoperative blood loss was (150.0±84.5) ml without blood transfusion, and the postoperative hospital stay was (6.5±2.5) d. There were no serious complications or deaths in the perioperative period, 2 cases had microbile leakage, and recovered by themselves 5-10 days after the operation; the patients were followed up for 6-12 months, no loss of follow-up, no recurrence of liver and abdominal hydatid.Conclusions:In the process of diagnosis and treatment of liver single cystic lesions, we should pay attention to the differential diagnosis of atypical CE1 hepatic cystic echinococcosis and simple liver cyst. The effective differential rate of abdominal spiral CT, hydatid immune experiment and abdominal ultrasound is low, which is easy to be misdiagnosed and missed. The high frequency probe of abdominal ultrasound can effectively find atypical CE1 hepatic cystic echinococcosis. Laparoscopic technique is not only an effective diagnosis method but also a treatment method. It is necessary to choose a reasonable operation method according to the patient's hydatidosis. Laparoscopic operation is safe and feasible in the treatment of hepatic cystic echinococcosis.

AIM:To investigate the changes in parameters related to myocardial fibrosis of H2 relaxin (H2RLX) and procollagen type I C-terminal peptide (PICP),transforming growth factor-?1 (TGF-?1) level in the plasma after acute anterior myocardial infarction. METHODS:Forty-one patients with anterior myocardial infarction (MI) and 10 controls with normal coronary vessels were selected. Plasma H2RLX,PICP,and TGF-?1 levels were determined by enzyme linked immunosorbent assay (ELISA) in 10 control subjects and 41 post-MI patients at day 3 and 7 post-MI. RESULTS:(1) H2RLX level at day 3 post-infarct had no difference between the patients and the controls. No marked change in H2RLX at day 3 versus day 7 post-infarct was observed. (2)The level of PICP at day 3 post-infarct was markedly increased followed by a fall at day 7 post-infarct,but was still higher than that in control. (3) TGF-?1 level,which was similar at day 3 and 7 post-infarct,was higher than that in control. (4) At day 7 post-infarct,the level of H2RLX was positively correlated with the fasting blood glucose in MI group. CONCLUSION:In early period of acute MI,profibrotic factors such as TGF-?1 expression and collagen expression increase. However,antifibrotic relaxin has no change.
