Objective To investigate the efficacy and feasibility of extra-peritoneal larparoscopic radical prostatectomy (eLRP) in the treatment of patients with high-risk prostate cancer (HRPC).Methods From February 2009 to December 2013,121 patients,who were diagnosed as HRPC according to the D'Amico definition,were received eLRP.The mean age was 70 years old (range 54 ～ 82 years old).The mean PSA level was 25.45 (range 2.40 ～ 111.31) μg/L and mean Gleason score was 8 (range 6 ～ 10).The classification of clinic stage in this study included 52 cases in cT1-cT2b,58 cases in cT2c,8 cases in cT3a,and 3 cases incT3b,respectively.The perioperative data were collected,including operative time,blood loss,intraoperative complications,urine leakage,lymph leakage,incontinent ability,erectile function and changing of PSA level.Results All the operations were successfully performed.The mean operative time was 165 minutes (range 105 ～341min),the average blood loss was 150 ml(range 50 ～ 1500ml).The intraoperative complications included hemorrhage in 4 cases and intra-operative obturator nerve injury in 3 cases.The mean duration of intestinal function recovery was 35h (range 24 ～72h) The mean interval of catheter indwelling was 9 days (range 7 ～14 days).The anastomotic leakage was found in 12 cases,including 1 day after surgery in 5 cases,2 days after surgery in 3 cases,3 days after surgery in 2 cases,4 day after surgery in 1 case and 5 day after surgery in 1 case.The anastomotic stricture in 3 cases within 2 to 4 months after operation,which the symptom improved after urethral dilation in 2 cases and urethrotomy in 1 case.Deep vein thrombosis was noticed in 1 case 5 days after the procedure.And lymphatic fistula was recorded in 1 case after the operation.Positive surgical margin,seminal vesicle invasion,and positive iliac vessel lymph node were found in 18,21,and 9 patients,respectively.The mean hospitalization duration was 10 days (range 5 ～ 22 d).Of the 107 patients followed-up,Ninety-six patients were continent in 1 year,except other 11 patients.Nerve sparing procedure was performed in 51 patients,and thirty-three of them were potent.The mean PSA level was 0.14 μg/L (range 0 ～8.75 μg/L) six weeks after the surgey.Fourty-eight patients had biochemical recurrence with 5 ～36 months followed-up,mean 18 months.Conclusions Extraperitoneal LRP is an efficacious approach for patients with high-risk prostate cancer.

To observe the protective effects of echinacoside on rotenone-induced damages in rats.

Objective: To observe hypoglycemic effects of Yunu Decoction, Zuogui Pill and Shenqi Pill, three compound traditional Chinese herbal medicines, in treatment of diabetes mellitus induced by alloxan in rats, and to compare the therapeutic effects among the three recipes for nourishing yin, clearing away heat, and nourishing yin and warming yang. Methods: Diabetes mellitus was induced in rats with alloxan at a dose of 60 mg/kg via tail vain injection. The diabetic rats were randomly divided into four groups: alloxan model group, Yunu Decoction-treated group, Zuogui Pill-treated group and Shenqi Pill-treated group. Rats in the three recipe groups were administered intragastrically with water extraction of Yunu Decoction, Zuogui Pill, and Shenqi Pill accordingly for 10 days. Then the level of blood glucose was measured by glucose oxidase method and the glucose tolerance was determined. Results: Compared with the normal rats, blood glucose level in the alloxan model group was obviously increased (P<0.05). Glucose levels in the three recipe groups were obviously decreased as compared with the alloxan model group (P<0.05), and glucose level in the Yunu Decoction-treated group after treatment was significant lower than before treatment (P<0.05). The glucose tolerance test indicated that rats in the alloxan model and three recipe groups revealed impaired glucose tolerance as compared with the normal rats, and there were no significant differences between the alloxan model group and the three recipe groups. Conclusion: Yunu Decoction, Zuogui Pill and Shenqi Pill can effectively decrease the glucose level of the rats with diabetes mellitus induced by alloxan, and Yunu Decoction showed the best therapeutic effects. The glucose tolerance test shows that the three recipes cannot correct the abnormal metabolism of glucose.

Objective To explore the relationship between clinical manifestations and pathological changes in diabetic nephropathy (DN) and to assess the predictive power of the pathologic classification for DN established by the Renal Pathology Society in 2010.Methods Patients with type 1 or type 2 diabetes and biopsy-proven DN in the Third Affiliated Hospital of Sun Yat-sen University between January 2004 to June 2014 were enrolled in the present study and were followed-up until 31 December 2014.The outcome was defined as renal end-points including renal replacement therapy and doubling of serum creatinine as well as all-cause mortality.The laboratory and histologic data were analyzed and outcomes were assessed using survival analysis.Results Fifty-seven people enrolled in this study were categorized into Class Ⅱa (n=9),Class Ⅱb (n=9),Class Ⅲ (n=25) and Class Ⅳ (n=14) while no participants belonged to Class Ⅰ.The changes of Class Ⅱa were slight and those of Class Ⅳ were severe both in the clinical data (diabetic duration,blood pressure,estimated glomerular filtration rate,urine protein excretion rate,albumin and hemoglobin) and the pathological data (percentage of global glomerulosclerosis,percentage and scoring of interstitial fibrosis and tubular atrophy,scoring of interstitial inflammation and incidence of large vessel lesions).There were no significant differences between Class Ⅱb and Ⅲ in the above variables except for the scoring of arteriosclerosis.The mean follow-up duration was 25.9 months.Twenty-five patients (43.9％) reached the renal outcomes and six people (10.5％) reached all-cause mortality.The survival analysis showed that there were significant differences among the renal survival curves of different glomerular classes and of different interstitial and vascular scorings,but not in the survival curves related to all-cause mortality.Conclusions The glomerular classes are not completely associated with renal prognosis.The clinical manifestations and renal outcomes are benign in Class Ⅱa,moderate but similar in Class Ⅱb and Ⅲ and severe in Class Ⅳ.The glomerular classification and interstitial and vascular scorings are associated to renal prognosis while their associations with mortality remain to be verified.

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

OBJECTIVETo assess the differences in the health promotion demand of practitioners between urban and rural private enterprises by a comparative analysis, and to probe into the more scientific and targeted health promotion measures.

METHODSStratified cluster random sampling and self-designed questionnaire were adopted to survey 852 practitioners in urban and rural private enterprises of a Chinese city.

RESULTSThere were significant differences in practitioners between the two sorts of enterprises in terms of age, length of service, educational level, and forms of employment (P < 0.05 or P < 0.01). The basic knowledge and skills of practitioners in rural private enterprises were worse than those in urban private enterprises(P < 0.05 or P < 0.01). Practitioners in rural private enterprises were significantly less inclined to gain basic health promotion knowledge through enterprise training and network(P < 0.01). The demand of practitioners for health examination and hazard notification was significantly lower in rural private enterprises than in urban private enterprises (P < 0.05).

CONCLUSIONFocused and targeted health promotion should be carried out based on different demand characteristics of practitioners in rural and urban private enterprises.

AIM: To evaluation the effects of esketamine and butorphanol on postoperative pruritus induced by epidural morphine injection in cesarean delivery parturients. METHODS: A total of 162 parturients who underwent elective cesarean section under continuous epidural anesthesia in Taizhou Central Hospital (Taizhou University Hospital), were selected and randomly divided into esketamine group (group K), butorphanol group (group B) and blank control group (group C). 5min after umbilicus amputation, parturients in group K was injected with 3 mg morphine diluent through epidural catheter, and esketamine 0.2 mg/kg intravenously. Parturients in groups B and C were given the same dose of morphine,and butorphanol 10 μg/kg or the same volume of normal saline, respectively. The incidence of postoperative pruritus at different times, the degree of pruritus and incidence of other adverse reactions were compared among three groups. RESULTS: The highest incidence of pruritus occurred within 4 hours after operation. The incidence of postoperative pruritus at 4 hours in group K and B was significantly lower than that in group C (3.7% vs. 3.7% vs. 29.6%, P < 0.05), the total incidence of postoperative pruritus within 48 hours was also significantly lower than that in group C (13.0% vs. 11.1% vs. 40.7%, P < 0.05), and the incidence of moderate to severe pruritus was also significantly lower than that of group C (5.6% vs. 3.7% vs. 31.5%, P < 0.05). There was no significant difference between group K and group B (all P > 0.05). There were no significant differences in the incidence of postoperative nausea, vomiting, dizziness and postoperative pain scores among three groups (P > 0.05). CONCLUSION: Both esketamine and butorphanol can reduce the incidence and degree of pruritus caused by epidural morphine injection in parturients, without affecting the analgesic effect of morphine and without increasing the incidence of adverse reactions. Esketamine is as effective and safe as butorphanol in preventing pruritus after cesarean section.

Objective:To summarize clinical characteristics of and treatment experience with patients with critical illnesses in a dermatological ward.Methods:All patients with serious or life-threatening conditions, who were hospitalized at the dermatological ward of the Second Xiangya Hospital of Central South University from July 9, 2011 to December 31, 2020, were collected, and their clinical data were retrospectively analyzed. Demographic characteristics, disease types and proportions, main complications, causes of serious or life-threatening conditions, important treatment measures and outcomes were summarized, and causes of death were also analyzed and discussed.Results:A total of 1 057 patients with critical illnesses were collected, with a male-to-female ratio of 1∶1.11, and 64.81% of them aged 18 to 65 years. The types of diseases mainly included drug eruptions (332 cases) , connective tissue diseases (226 cases) , bullous skin diseases (104 cases) , psoriasis (57 cases) , erythroderma (45 cases) , infectious skin diseases (67 cases) , etc. Among them, psoriasis (39 cases) and erythroderma (32 cases) mostly occurred in males, and connective tissue diseases (168 cases) mostly occurred in females. Common complications mainly involved infections, important organ damage or dysfunction, hypoalbuminemia, and fluid, electrolyte and acid-base imbalances. A total of 94 patients were diagnosed with life-threatening conditions, which were found to be mainly caused by primary skin diseases, hematologic abnormalities, respiratory failure, nervous system abnormalities, renal failure, sepsis, fluid, electrolyte and acid-base imbalances, etc. During the management of critical illnesses, 43 patients were treated with high-dose glucocorticoid pulse therapy, 264 were treated with gamma-globulin pulse therapy, 355 were transfused with other blood products, and 34 received special therapies such as hemoperfusion/immunoadsorption therapy, plasma exchange, dialysis, artificial liver support therapy; 42 patients were transferred to the intensive care unit (ICU) , 12 were transferred to the department of surgery for operations, and 12 were transferred to the department of obstetrics and gynecology for delivery or induction of labor. After treatment, 989 patients (93.57%) achieved improvement and were discharged. A total of 14 patients (1.32%) died, of whom 7 died of secondary sepsis, 2 died of severe pulmonary infections, 2 died of asphyxia caused by respiratory mucosa shedding-induced airway obstruction, the other 3 died of gastrointestinal hemorrhage, cerebral hemorrhage and neuropsychiatric systemic lupus erythematosus, respectively.Conclusions:Critical cases in the dermatological ward mainly suffered from serious skin diseases such as severe drug eruptions, connective tissue diseases and bullous skin diseases, as well as complications such as severe underlying diseases, severe organ dysfunction, sepsis or severe fluid, electrolyte and acid-base imbalances. In terms of treatment, it is of critical significance to make a clear diagnosis and assess the severity of disease as early as possible, monitor and prevent possible complications, and to consult with specialists in relevant disciplines in time.
