Objective To observe the efficacy of Zishen Ningxin capsule combined with telmisartan in the treatment of perimenopausal hypertension,and its influence on the patients'blood pressure,biochemical indexes and TCM symptom scores.Methods 300 patients with perimenopausal hypertension were randomly divided into control group and observation group with 150 patients in each group.The control group was given telmisartan treatment,and the observation group was given Zishen Ningxin capsule on the basis of the control group.The treatment course of both groups was 8 weeks.The dynamic blood pressure and coefficient of variation of blood pressure at 24 h before and after treatment were observed and compared between two groups(24 h systolic blood pressure and coefficient of variation,24 h diastolic blood pressure and its coefficient of variation),sex hormone levels(serum estradiol,follicle stimulating hormone,testosterone,progesterone),blood lipid levels(triacylglycerol,total cholesterol,low density lipoprotein cholesterol,high density lipoprotein cholesterol),renin and hypersensitive C-reactive protein levels,as well as the changes of TCM symptom score were evaluated for the efficacy of the two groups.Results After treatment,the 24 h systolic blood pressure and its coefficient of variation,24 h diastolic blood pressure and its coefficient of variation,the levels of sex hormones,blood lipids,renin and hypersensitive C-reactive protein,as well as TCM symptom scores in two groups were significantly improved(P＜0.05),and all indexes in the observation group were better than those in the control group(P＜0.05).The total effective rate of observation group was significantly higher than that of control group(P＜0.05).There was no significant difference of the incidence of adverse reactions in the two groups(P＞0.05).Conclusion Zishen Ningxin capsule combined with telmisartan has significant clinical efficacy in the treatment of perimenopausal hypertension,which can effectively reduce blood pressure,relieve symptoms,improve the levels of sex hormones,blood lipids,renin and hypersensitive C-reactive protein.

ObjectiveTo explore the relationship between smoking behavior and related factors among the adult residents in Fengxian District,so as to provide an evidence for carrying out tobacco control and other health promotion work. MethodsA multi-stage stratified cluster random sampling method was used to select 2 272 community residents aged between 15 and 69 yeas to carry out the questionnaire survey. ResultsIn 2020, the smoking rate of adult residents in Fengxian District was 23.50%. Smoking behavior was statistically correlated with age, gender, household registration, chronic disease, occupation and educational level. Smoking behavior was inversely correlated with educational level. Smoking rate of male residents was significantly higher than that of female residents, smoking rate of residents with chronic diseases was significantly higher than that of those without suffering from chronic diseases, and smoking rate of permanent registered residents was significantly higher than that of those non-locals. The highest smoking prevalence was among retired and freelancers, followed by staff of government agencies and public institutes, while the lowest was among students, followed by intellectuals. Multivariate logistic regression analysis showed that gender, age and education level were the main factors affecting the smoking prevalence level. ConclusionThe general　smoking rate of adult residents in Fengxian District was higher than the average level in Shanghai but lower than the national level. Male residents aged ≥25 years and with lower education level are the key invention targets for tobacco control.

Objective:To study the efficacy of different surgical methods in treatment of hilar cholangiocarcinoma (HCCA), and to analyze the factors affecting long-term prognosis of HCCA patients after surgical treatment.Methods:The clinical data of 105 patients who underwent surgical treatment for HCCA at the First Affiliated Hospital of Soochow University from April 2010 to October 2021 were retrospectively analysed. There were 58 males and 47 females, with age (64.2±10.6) years old. Data analysed included surgical treatments, postoperative pathological data, perioperative complications and survival on follow-up. The Kaplan Meier survival curve was plotted, and the log-rank test and Cox proportional hazard model were performed to analyze the key factors affecting long-term prognosis.Results:Of 105 patients, 4 (3.8%) patients died during the perioperative period, and 58 patients (55.2%) developed complications with included 32 (30.5%) patients with pleural effusion and 12 (11.4%) patients with biliary leakage. The follow-up data was available in 85 patients with the overall median survival time of 19 months, and the 1-, 3-, 5-year cumulative survival rates of 58.1%, 27.0% and 24.8% respectively. The 1-, 3-, and 5-year cumulative survival rates for the R 0 resection patients ( n=59) were 69.4%, 36.2%, 27.4%, respectively, which were significantly better than 49.4%, 12.3%, 0% for the R 1/2 resection patients ( n=20), and 0% for the palliative drainage patients ( n=6) (all P<0.05). Univariate analysis and Cox multivariate analysis showed that age ≥70 years ( HR=2.158, 95% CI: 1.175-3.965), preoperative CA19-9 level ≥1 015 U/ml ( HR=1.981, 95% CI: 1.009-3.894), resection margin ( HR=2.587, 95% CI: 1.371-4.881), and lymph node metastasis ( HR=2.308, 95% CI: 1.167-4.567) were independent risk factors for long-term prognosis of HCCA patients (all P<0.05). Conclusions:R 0 resection was an effective way to prolong survival of patients with HCCA. Age, preoperative CA19-9 level, resection margin and lymph node metastasis were related to long-term survival of HCCA patients.

In recent years, society has gradually shifted from a "fearful" approach of unscientific plan design, unbalanced resource protection and inadequate management experience leading to the spread of public panic and negative emotions to a "comfortable" approach of proactive prevention, precise control, information symmetry, scientific response and systematic treatment in the face of public health emergencies. College students are increasingly becoming the "key minority" to participate in crisis management. This is mainly due to their values in line with social ideals, their mobility in line with disciplinary practice and volunteerism, their knowledge accumulation in multi-disciplinary cross-fertilization, and their good cognitive thinking literacy, high information media literacy and perfect social support system. Therefore, this group has a strong comprehensive advantage in public health emergencies. Based on this background, combined with on-site investigation and interview feedback, this paper considered that this group can play an active role in normal prevention and early warning beforehand, information transmission and communication at the moment the event occur, corrective cognitive implementation and disposal in the event, and scientific research innovation and popularization afterwards, so as to better play an increasingly important leading demonstration effect in public health emergencies. At the same time, it can also encourage universities to take the initiative in the process of talent training to teach people according to the concept of "change according to the matter, advance according to the time and new according to the situation", and lead college students of different majors to maximize the pioneering effect of role models in public health emergencies.

Blood-brain barrier (BBB) damage after ischemia significantly influences stroke outcome. Compound LFHP-1c was previously discovered with neuroprotective role in stroke model, but its mechanism of action on protection of BBB disruption after stroke remains unknown. Here, we show that LFHP-1c, as a direct PGAM5 inhibitor, prevented BBB disruption after transient middle cerebral artery occlusion (tMCAO) in rats. Mechanistically, LFHP-1c binding with endothelial PGAM5 not only inhibited the PGAM5 phosphatase activity, but also reduced the interaction of PGAM5 with NRF2, which facilitated nuclear translocation of NRF2 to prevent BBB disruption from ischemia. Furthermore, LFHP-1c administration by targeting PGAM5 shows a trend toward reduced infarct volume, brain edema and neurological deficits in nonhuman primate

Objective: To review the research progress of medicine biomaterials in prevention and treatment of adhesion after tendon injury, and to provide reference for clinical treatment. Methods: The literature on the application of medical biomaterials in the prevention and treatment of tendon adhesions in recent years was reviewed, and the biological process, treatment methods, and current status of tendon adhesions were summarized. Results: Tendon adhesion as part of the healing process of the tendon is the biological response of the tendon to the injury and is also a common complication of joint dysfunction. Application of medical biomaterials can achieve better biological function of postoperative tendon by reducing the adhesion of peritendon tissues as far as possible without adversely affecting the tendon healing process. Conclusion: The use of medical biomaterials is conducive to reduce the adhesion of tendon after operation, and the appropriate anti-adhesion material should be selected according to the patients' condition and surgical needs.

Objective:To investigate the application of anterolateral thigh chimeric perforator flap in repairing complex soft tissue defects in lower extremities.Methods:From January, 2015 to June, 2019, 76 cases of complex soft tissue defects in lower extremities were repaired with free anterolateral thigh chimeric perforator flap pedicled with the descending branch of lateral circumflex femoral artery, including 29 cases in shank and 47 cases in ankle, and all had various tissue necrosis, infection, deep tissue defect and orthopaedic implant exposure. The size of the wound ranged from 15 cm×8 cm to 35 cm×20 cm, in which 45 cases associated with dead cavity formation, 62 cases with combined fractures at the same site, and 38 cases with combined fractures or other system injuries in other sites. After debridement, VSD treatment, good wound granulation and infection control, the chimeric perforator flap pedicled with the descending branch of the circumflex lateral femoral artery was designed and harvested. The perforator flap was used to repair most of the wounds with deep tissue exposures, the muscle flap was used to fill the dead cavity and (or) cover the wound around the flap, and free skin was grafted of the muscle flap at the first or second stage. Scheduled follow-up was conducted after the operation.Results:All 76 flaps survived, including vascular crisis occurred in 2 cases within 72 hours after surgery and ceased after immediate surgical exploration. One case had a further surgical operation due to excessive bleeding. Partial necrosis occurred at the distal end of the flap or the skin graft area of the muscle flap in 4 cases, of which 2 cases were treated with grafted skin again and the other 2 cases completely eliminated the wound after active dressing change. Other 16 cases of post-traumatic osteomyelitis with bone defect were repaired respectively with bone grafting, bone transportation or Masquelet technique in 3 to 6 months after wound healing. Among the 76 cases, 68 cases had primary wound healing while 8 cases delayed. Seventy-one cases were followed-up from 9 to 24 months, with an average of 16 months, while 5 cases lost. The appearance and function of the affected limbs recovered satisfactorily without recurrence of infection.Conclusion:With the anterolateral thigh chimeric perforator flap transplantation, the perforators flap can be conveniently used to repair the wound, and the muscle flap can be used to fill dead cavity and(or) deep wounds with free skin graft. Only the descending branch of lateral circumflex femoral artery is required to be anastomosed. It achieves a 3-dimensional effective reconstruction of the complex wound in extremities. It is a safe and effective technique to repair and reconstruct the complex wound in lower extremities and ideal in clinical applications.

Objective:To explore the diagnostic value of laparoscopy in the postoperative recurrence of peritoneal metastasis in gastric cancer, and to investigate the efficacy of bidirectional intraperitoneal and systemic (BIPS) chemotherapy for the recurrence.Methods:The descriptive case series study was conducted. Case inclusion criteria: (1) gastric cancer patients without synchronous distant metastasis received D2 radical gastrectomy; (2) postoperative adjuvant chemotherapy was administered; (3) no other distant metastasis except recurrence of peritoneal metastasis; (4) age of 18-75 years; (5) Eastern Cooperative Oncology Group (ECOG) performance-status score≤2; (6) pretreatment evaluation suggested that surgery and chemotherapy could be tolerated. Eight consecutive gastric cancer patients with postoperative recurrence of peritoneal metastasis who met the above criteria at Department of Gastrointestinal Surgery of Ruijin Hospital from September 2015 to September 2016 were enrolled into the study. There were 6 males and 2 females with the median age of 52 (38-68) years. They received laparoscopy or laparotomy first, and then were evaluated with reference to the Sugarbaker peritoneal cancer index (PCI) and the peritoneal metastasis classification of gastric cancer developed by the Japanese Gastric Cancer Research Association. A peritoneal access port was implanted in the subcutaneous space of the lower abdomen and the patients received chemotherapy for 21 days as a course of treatment. All the patients received intraperitoneal 20 mg/m 2 of paclitaxel (PTX) via implanted subcutaneous peritoneal access ports and intravenous 50 mg/m 2 of PTX at day 1 and day 8, meanwhile 80 mg/m 2 of Tigio was orally administered per day for 14 consecutive days, followed by 7 days of interval. Follow-up ended on December 15, 2019. Results:Of these 8 patients with recurrence of peritoneal metastasis after gastric cancer surgery, 1 case underwent laparotomy and loop stoma of terminal ileum because of complete colonic obstruction, and the remaining 7 cases underwent laparoscopy successfully and the recurrence of peritoneal metastasis was clearly diagnosed. Two patients with ovarian metastasis underwent laparoscopic bilateral adnexectomy. The median follow-up time was 17.5 (1.5 to 39.0) months, the median number of BIPS chemotherapy course was 11 (1 to 30), and the median survival time (MST) after BIPS chemotherapy was 17.0 months. The major adverse reaction in BIPS treatment was mainly myelosuppression, of which grade 3/4 leukopenia and neutropenia developed in 1 and 2 cases respectively. No BIPS-related death occurred. The MST of gastric cancer after radical gastrectomy was 40.0 months.Conclusions:Laparoscopy is a safe and feasible method for diagnosing the recurrence of peritoneal metastasis of gastric cancer. BIPS chemotherapy is effective and safe for its treatment and deserves further study.

Objective: To investigate the clinical effects of primary revision after artificial hip replacement and causes of revision surgery. Methods: A total of 344 patients who underwent revision surgery after total hip arthroplasty (THA) and artificial femoral head replacement from January 2010 to December 2016 were retrospectively analyzed. There were 141 males and 203 fe-males, with a mean age 65.64±10.81 years (28-87 years). A total of 351 hip revisions were performed in 344 patients with 7 pa-tients in bilateral revisions. All patients were followed up for 60.38±22.75 months (24-105 months). All patients with periprosthet-ic infection underwent two-stage revision after prosthesis placement, and all others underwent one-stage revision. The clinical out-comes of revision surgery were assessed with the Harris hip score and the survival rate of the revision prosthesis. According to the duration from artificial hip replacement to revision surgery, all patients were divided into early revision (less than 5 years) and late revision (more than 5 years) groups. They were also divided into two groups according to the age of the patient in revision sur-gery: >55-year-old and ≤55-year-old groups. The causes of revision, hip reoperation and re-revision were recorded. Results: In the 351 hip revisions, a total of 238 (67.8%) had aseptic loosening, 41 (11.7%) periprosthetic fractures, 30 (8.5%) periprosthetic infection, 23 (6.6%) recurrent dislocation and 19 (5.4%) the eccentric liner wear. The infection rate was significantly higher in the early revision group (21.1%) than that in the late revision group (4.2%) (χ²=24.443, P<0.001). The aseptic loosening rate was sig-nificantly higher in the late revision group (72.4%) than that in the early revision group (54.4%) (χ²=9.899, P=0.002). Sixteen pa-tients underwent hip surgery after revision, including 6 recurrent dislocations, 4 aseptic loosening, 3 periprosthetic fractures, and 3 periprosthetic infections. Eight of them underwent revision surgery, including 4 cases of aseptic loosening, 2 cases of periprosthet-ic fractures, and 2 cases of recurrent dislocation. The duration from the primary revision to the second revision was 22.1±10.0 months (1-75 months). The 5-year and 8-year survival rates of the revision prostheses were 99.3%[95%CI(98.3%, 100.3%)] and 92.6% [95%CI(87.1%, 98.1%)], respectively. The proportions of prosthetic infection and eccentric liner wear in the ≤55-year-old group were significantly higher than those in the >55-year-old group (χ²=3.981, P=0.046; χ²=5.226, P=0.022), while the propor-tion of aseptic loosening in the >55-year-old group was significantly higher than that in the ≤55-year-old group (χ²=5.254, P=0.022). The 8-year survival rates of the revision prostheses of ≤55-year-old group and >55-year-old group were 76.8% [95%CI(50.5%, 103.1%)] and 95.4% [95%CI(91.1%, 99.7%)], respectively. Conclusion Young patients have a higher risk of re-revi-sion after revision THA.
