Objective:To investigate blood glucose management in elderly diabetic patients and the factors that affected achieving high rates of achieving it.Methods:The quality of blood glucose control by elderly diabetic patients who visited five community health service centers in Beijing in June 2022 was surveyed retrospectively using a questionnaire.Participants were divided into the high-quality group and not high-quality groups by the criteria of glycosylated hemoglobin(HbA 1C)<7% without hypoglycemia and weight gain.Single factor analysis and multiple-stepwise Logistic regression analysis were used to identify the relative risk of factors affecting the achievement of good glucose management. Results:A total of 287 valid questionnaires were collected, including 80 cases(27.9%)in the high-quality group and 207 cases(72.1%)in the not high-quality group.There were significant differences in sex, course of disease, occurrence of hypoglycemia, number of chronic complications, medication, alcohol consumption, dietary changes, missed medication doses, prolonged outpatient visit intervals, and depressive mood between the two groups( P<0.05).Multivariate stepwise logistic regression analysis showed that insulin use, missed medication ≥ 1 time/week, and prolonged outpatient visit intervals were independent risk factors for good control( P<0.05). Conclusions:The percentage of elderly diabetes patients with good blood glucose control was low.Factors affecting the rate included insulin use, medication compliance, and prolonged outpatient visit intervals.

Objective:To investigate changes in the self-management ability of chronic diseases in elderly diabetic patients during the novel coronavirus pneumonia pandemic.Methods:A multi-stage cluster sampling method was used to retrospectively collect diabetes management information from elderly diabetic patients treated in five community health service centers in Beijing in June 2022, including 295 elderly diabetic patients, and changes in management of their self-care practices such as diet, exercise, medical treatment and medication, blood glucose monitoring, complication management, and psychological states before and after the outbreak(2019-2022)were analyzed.Results:In 295 elderly diabetic patients, increased glycated hemoglobin( P<0.05)and body mass index(BMI)( P<0.05)were observed during the pandemic.Among 115 patients with underlying diabetic complications, 75.7%(87)of patients had worsening symptoms of chronic complications of diabetes and a shortened weekly exercise time[124(60, 300)min vs.140(60, 300)min, Z=6.00, P<0.05].The number of weekly blood glucose tests was reduced(5.6±4.2 vs.5.8±4.3, t=3.17, P<0.05).The weekly time spent interacting with family members increased( P<0.05).There were no significant differences in body weight, sleep time, and number of times of forgetting to take medication per week before and after the outbreak( P>0.05).21.0% of patients had a decrease in the number of hospital visits, and 72.2% of patients experienced low mood and increased adverse psychological emotions during the pandemic. Conclusions:The pandemic has had a negative impact on the management of chronic diseases in elderly diabetic patients, mainly reflected in the reduction of exercise time and blood glucose monitoring.It also affected regular hospital visits of patients, resulting in negative psychological emotions, poor blood glucose control, increased BMI, and aggravated symptoms of chronic complications, compared with their pre-pandemic conditions.

Objective:intrahepatic portocaval shunt (TIPS) in the treatment of hepatic sinusoidal obstruction syndrome (HSOS).Methods:A retrospective analysis was performed on 27 patients with HSOS who were treated with TIPS in our center from July 2018 to July 2020. The changes of portal vein pressure (PVP), portal vein pressure gradient (PPG) and liver function were observed, so as to evaluate the efficacy. Paired t test was adopted to evaluate the quantitative parameters, while χ2 test was used to analyze qualitative parameters, with P < 0.05 as statistical difference. Results:PVP decreased from (4.41 ± 0.18) kPa before shunt to (2.69 ± 0.11) kPa after shunt ( t = 82.41, P < 0.001), PPG decreased from (3.23 ± 0.18) kPa before shunt to (1.46 ± 0.23) kPa after shunt ( t = 32.41, P < 0.001). The liver function improved significantly after operation. After 24 months of follow-up, 3 patients developed stent restenosis and recanalized after balloon dilation. Three patients developed hepatic encephalopathy, which was improved after drug treatment. One patient underwent liver transplantation due to liver failure. Conclusion:TIPS is effective in the treatment of HSOS in the short and medium term, and can provide time for liver transplantation patients to wait for liver source.

Objective:To investigate the prognosis of robotic pancreatoduodenectomy after the learning curve and open pancreatoduodenectomy for pancreatic cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 396 patients who underwent curative pancreatoduodenectomy for pancreatic duct adenocar-cinoma in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from January 2017 to December 2018 were collected. There were 244 males and 152 females, aged 64(range, 36?92)years. Of 396 patients, 86 cases undergoing robotic pancreatoduodenectomy were divided into robotic group, 310 cases undergoing open pancreatoduodenectomy were divided into open group. Observa-tion indicators: (1) propensity score matching and comparison of general data between the two groups after matching; (2) follow-up and survival analysis. Follow-up was conducted by telephone interview or outpatient examinations including tumor markers and abdominal imaging examina-tions to detect survival of patients up to March 2022. Overall survival was defined as the time from the surgery date to death or the last follow-up. Disease-free survival was defined as the time from the surgery date to tumor recurrence or the last follow-up. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Normality of measurement data was examined using the Shapiro-Wilk test. Measurement data with skewed distribution were described as M(range), and comparison between groups was analyzed using the Mann-Whitney rank-sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used for survival analysis. An intent-to-treat analysis was performed in this study, patients who were converted to laparotomy from robotic surgery were still divided into the robotic group. Results:(1) Propensity score matching and comparison of general data between the two groups after matching: 164 of 396 patients had successful matching, including 82 cases in robotic group and open group, respectively. Before propensity score matching, the body mass index, cases in stage T1, T2, T3, T4, cases in N0, N1, N2 were 23.4(range, 21.4?25.3)kg/m 2,24, 41, 10, 11, 52, 27, 7 for the robotic group, versus 22.4(range,20.3?23.9)kg/m 2,57, 144, 22, 87, 131, 132, 47 for the open group, showing significant differences in the above indicators between the two groups ( Z=3.01, 2.63, 3.03, P<0.05). After propensity score matching, cases of males, age, body mass index, cases with American Society of Anesthesiologists (ASA) score as 1, 2, 3, CA19-9, cases with preoperative biliary drainage, cases with portal vein resection, cases with pancreatic resection margin <1 mm, cases in stage T1, T2, T3, T4, cases in stage N0, N1, N2, cases with nerve invasion, cases with tumor differentiation as high-medium differentiation, medium-low differentiation, low differentiation, cases with adjuvant chemotherapy were 51, 65(range, 59?69)years, 23.0(range, 21.0?25.2)kg/m 2, 32, 41, 9, 160.4(range, 46.7?377.2)U/mL, 21, 9, 8, 21, 40, 10, 11, 48, 27, 7, 76, 26, 47, 9, 53 for the robotic group, versus 58, 65(range, 58?69)years, 23.3(range, 21.4?25.3)kg/m 2, 35, 39, 8, 172.0(range, 69.7?402.9)U/mL, 26, 9, 10, 24, 40, 7, 11, 49, 28, 5, 76, 22, 49, 11, 57 for the open group, showing no significant difference in the above indicators between the two groups ( χ2=1.34, Z=0.18, 0.34, 0.49, 0.51, χ2=0.75, 0.00,0.25, Z=0.59, 0.27, χ2=0.00, Z=0.76, χ2=0.44, P>0.05). (2) Follow-up and survival analysis: after propensity score matching, 164 patients were followed up for 54(range, 1?67)months. The follow-up time of patients was 55(range, 51?59)months for the robotic group, versus 54(range, 50?58)months for the open group, respectively, showing no significant difference between the two groups ( Z=0.48, P>0.05). During the follow-up, the 1-year overall survival rate, 3-year overall survival rate, the median survival time, 1-year disease-free survival rate, 3-year disease-free survival rate, the median disease-free survival time, tumor recurrence rate, cases with recurrence pattern as local recurrence, liver recurrence, other distant recurrence, local and distant recurrence were 81.7%, 39.0%, 27 months(95% confidence interval as 19?33 months), 61.0%, 34.2%, 15 months(95% confidence interval as 12?18 months), 54.9%(45/82), 12, 16, 9, 8 for the robotic group. The above indicators were 79.3%, 36.0%, 24 months(95% confidence interval as 19?31 months), 59.8%, 27.5%, 15 months(95% confidence interval as 10?20 months), 58.5% (48/82), 10, 22, 6, 10 for the open group. There was no significant difference in overall survival or disease-free survival between the two groups ( χ2=0.39, 0.47, P>0.05). There was no significant difference in tumor recurrence rate or tumor recurrence site between the two groups either ( χ2=0.22, 1.86, P>0.05). Conclusion:After the learning curve, robotic pancreato-duodenectomy has non-inferior prognosis compared with open pancreatoduodenectomy.

In 319 cases who met the inclusion criteria.Result:There were complications in 41 cases and no death;The average portal vein pressure before and after thrombus clearance treatment was (25.6±4.9) mmHg and (14.7±4.1) mmHg respectively ( t=2.53, P<0.05); Thrombus decreased significantly in most patients. Conclusion:Invasive therapy is a safe and effective method for patients complicated with portal vein thrombosis after splenectomy or devascularization.

The gut microbiota plays an important role in regulating the pharmacokinetics and pharmacodynamics of many drugs. FLZ, a novel squamosamide derivative, has been shown to have neuroprotective effects on experimental Parkinson's disease (PD) models. FLZ is under phase Ⅰ clinical trial now, while the underlying mechanisms contributing to the absorption of FLZ are still not fully elucidated. Due to the main metabolite of FLZ was abundant in feces but rare in urine and bile of mice, we focused on the gut microbiota to address how FLZ was metabolized and absorbed.

Objective To compare the effectiveness and safety of two different treatment methods for patients with polycystic liver disease using super selective hepatic arterial embolization. Methods This retrospective study enrolled 41 patients with polycystic liver disease treated from June 2008 to June 2016 in the First Medical Center of Chinese PLA General Hospital. The patients underwent transcatheter super-selective hepatic arterial embdization (TAE). There were 5 men and 36 women. The age ranged from 36 to 68 years. The patients were divided into the observation group (n=14) and the control group ( n=27). The observation group underwent treatment using an emulsion of iodized oil and bleomycin and N-butyl-2-cyanoacrylate. The control group underwent iodized oil and N-butyl-2-cyanoacrylate. The clinical symptoms, operative complications, volumes of intrahepatic cysts, hepatic parenchyma volumes of pre-TAE and post-TAE at 3, 6 months and every 6 monthly were compared. Results TAE was technically successful in all the patients. The follow-up periods ranged from 24 to 72 months. The clinical symptoms improved re-markably in the observation group at 3 month, 6 months, 12 months, and 24 months, being 92. 9% (13/14), 92. 9% (13/14), 92. 9% (13/14), 92. 3% (12/13), respectively. One patient was lost to follow-up 24 months after operation. The clinical symptoms improved remarkably in the control group at 3 month, 6 months, 12 months, and 24 months, being 88. 9% ( 24/27 ), 85. 2% (23/27), 84. 6% ( 22/26 ), 81. 8% (18/22), respectively. One patient was lost to follow-up 12 months after operation and five patients were lost to follow-up 24 months after operation. Compared with preoperative, the abdominal circumference of two groups had decreased, the total volume of intrahepatic cyst and liver decreased at 6 months, 12 months, and 24 months after surgery (P＜0. 05). Conclusions TAE was a safe and effective treatment for polycystic liver disease. Patients in the observation group had more effective treatment outcomes on follow-up.

Objective: To explore the skin condition and histological changes after face lift based on extended subcutaneous and sub-SMAS undermining and multiple accurate plication of SMAS system. Methods: Eighteen patients that underwent face lift were enrolled according to the inclusion and exclusion criterion. Objective, subjective and histological evaluations were performed to study the skin changes. Results: Nine patients completed the study and skin condition improved significantly after face lift from the objective and subjective results. Histological evaluation revealed that epidermal thickness increased along with dermal collagen content. Collagen and elastic fibers were more condensed after surgery than before, suggesting the dermal regeneration after face lift. Conclusions Skin regeneration after face lift can help maintain the postoperative result. Extensive subcutaneous dissection along with removal of lax skin as much as possible are the key points of face lift.

Objective To investigate the role of real-time PCR(qPCR) assay for EBNA fragments in quantitative detection of Epstein-Barr virus(EBV)DNA loads and the diagnose value of combining EBNA assay with common qPCR assay (designed on Bamh1-W fragments) in Nasopharyngeal Carcinoma (NPC) patients Methods EBV DNA loads of 234 blood samples(66 NPC samples included)were detected using two methods and DNA loads inside and outside cells were detected respectively. Positive rate obtained through different methods was compared. Regression analysis and t test were used to validate the methodology. Results Positive rate of EB-NA assay(53.42% in all samples and 51.52% in NPC samples)was lower than that of Bamh1-W assay(69.23%in all samples ,71.21% in NPC samples),however the combination of two methods could enhance the positive rate(70.94% in all samples,72.73% in NPC samples),especially in NPC samples. The correlation R2 of EBNA assay and Bamh1-W assay was 0.577(P < 0.05)and the difference was statistically significant. In NPC samples , R2 was 0.828 (P > 0.05) and it showed good correlation but the difference was not statistically significant. Conclusions The combination of EBNA assay and Bamh1-W assay can improve the positive rate in EBV DNA loads detection and its efficiency is more significant in NPC patients ,which shows significance in EBV DNA loads quantification and in the auxiliary diagnosis of NPC.

Objective To compare the clinical effect and safety of peroral endoscopic myotomy (POEM) with surgical therapy in treatment of esophageal achalasia. Methods 78 patients diagnosed as esophageal achalasia from January 2012 to October 2014 were enrolled in the study and divided into POME group and Heller group. There were 42 patients in POEM group and 36 patients in Heller group. The clinical symptom remission rate, LES resting pressure, Eckardt scores, complication rate, length of hospital stay and the hospitalization expenses were analyzed between the two groups. Results The patients in POEM group and Heller group both got clinical remissions after the treatment. There was no statistical difference in the rate of complication occurrence, Eckardt scores and LES resting pressure between the two groups. Patients in POEM group had shorter operation time, hospital stay and less expenses compared with the Heller group. Conclusions Compared with Heller group, the POEM group has the similar curative effect in treatment of esophageal achalasia. The POEM as a minimally invasive surgery has the advantages of less pain and trauma, shorter hospital stay, well tolerated and low cost. Therefore, the POEM is worth to be popularized and applied in treating esophageal achalasia.
