RESUMO
Objective:To evaluate the effect of comprehensive intervention measures on Yunnan unexplained sudden death (YUSD) in Dali Prefecture, Yunnan Province, and to provide scientific basis for improving the prevention and control measures.Methods:Since 2010, Yunnan Province had implemented comprehensive intervention measures in ward areas according to the etiological pattern of YUSD. In July 2019, 47 families with YUSD were selected as case families and 23 families without YUSD were selected as control families in 31 natural villages of Heqing, Xiangyun, Yunlong, Eryuan, Jianchuan, Binchuan and Nanjian counties of Dali Prefecture. A unified questionnaire was used to investigate the basic information, economic status, dietary structure, and health literacy of the families during the two periods of "the first sudden death case" and "the present".Results:The annual household income of the case families at present (median, 20 492.6 yuan) was significantly higher than that of the first sudden death case (3 883.4 yuan), and the difference was statistically significant ( Z = - 5.27, P < 0.001). At present, rice (76.6%, 36/47) was the main diet of the case families; at the time of the first sudden death case, 23.4% (11/47) of the case families could not eat enough, and there was no such situation in the case families at present. Compared with the time of the first sudden death case, the dietary habits of the case families at present were as follows: the proportion of eating Trogia venenata decreased from 19.0% (39/205) to 0 (0/190), the proportion of eating wild fruit decreased from 17.1% (35/205) to 9.5% (18/190), and the proportion of drinking raw water decreased from 55.1% (113/205) to 42.1% (80/190), and the differences were statistically significant (χ 2 = 22.37, 4.90, 6.86, P < 0.05). Lifestyle and health awareness: the proportion of those who washed their hands before meals and after using the toilet increased from 9.8% (20/205) to 41.6% (79/190), those who did not overwork increased from 16.6% (34/205) to 34.2% (65/190), and those who took good protection when spraying pesticides increased from 7.3% (15/205) to 21.6% (41/190), and the differences were statistically significant (χ 2 = 53.17, 33.94, 16.48, P < 0.001). Toilet habits: the proportion of using outdoor toilet decreased from 75.6% (155/205) to 9.5% (18/190), the difference was statistically significant (χ 2 = 175.21, P < 0.001). When the first sudden death case occurred, the proportions of eating Trogia venenata and using outdoor toilet in the case families were higher than those in the control families (χ 2 = 22.37, 23.70, P < 0.001), the proportions of those who washed their hands before meals and after using the toilet and those who did not overwork in the case families were lower than those in the control families (χ 2 = 7.38, 4.93, P < 0.05). Conclusions:The economic conditions, production and living conditions of YUSD areas in Dali Prefecture have been significantly improved, and the health literacy and health prevention awareness of the population have been greatly improved. Economic conditions and living standard, dietary structure and health literacy may be related factors of YUSD.
RESUMO
Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO2, NO2, CO, PM2.5, PM10, and maximum 8 h O3 concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM2.5, NO2, SO2, and O3 were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM2.5, NO2, SO2 and O3 were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.
RESUMO
Objective:To analyze common pathogenic gene mutations of arrhythmogenic right ventricular cardiomyopathy (ARVC) in Yunnan unexplained sudden death (hereinafter referred to as Yunnan sudden death) cases, and explore the etiological relationship between Yunnan sudden death and ARVC.Methods:Four typical Yunnan sudden death affected counties (cities) were selected as investigation sites. Cryopreserved autopsy cardiac cavity blood samples were collected from Yunnan sudden death cases ( n = 3), and peripheral venous blood samples were harvested from their relatives (first, second, third and immediate degree of kinship, n = 67) and control population ( n = 49). The DNA of blood samples was extracted for amplification and sequencing of 97 exons of 5 common ARVC desmosomal protein [desmoplakin (DSP), desmocollin-2 (DSC2), desmoglein-2 (DSG2), plakophilin-2 (PKP2) and junction plakoglobin (JUP)] genes, and genetic lineage of Yunnan sudden death cases was investigated. Results:A total of 17 gene mutation sites were discovered in Yunnan sudden death cases and their relatives, with 6, 5, 4, 1 and 1 in the DSP, DSC2, DSG2, PKP2 and JUP genes, which were not found in the control population. Among them, 9 were newly discovered mutation sites and 8 were reported mutation sites. The DSP gene exon 24 c.8472 G>C, a pure contractual sense mutation, was common in the relatives of 4 cases in the same family surveyed; and one immediate relative carried a deletion mutation at c.2368 - 2370 of exon 15 of DSC2 gene.Conclusion:Yunnan sudden death cases and their relatives carry mutations in the ARVC desmosomal protein DSP, DSC2, DSG2, PKP2, and JUP genes, and the onset of some Yunnan sudden death may be associated with mutations in the ARVC desmosomal protein genes.
RESUMO
Objective:To explore the relationship between arrhythmogenic right ventricular cardiomyopathy (ARVC) desmosomal protein gene mutations and Yunnan unexplained sudden death (hereinafter referred to as Yunnan sudden death) by detecting 5 common ARVC desmosomal protein gene mutations of Yunnan sudden death cases and their relatives in Heqing County, Yunnan Province.Methods:In January 2021, the autopsy heart cavity blood was collected from Yunnan sudden death cases in 8 villages in Heqing County, and peripheral venous blood samples of relatives of the cases were collected. Blood samples' DNA was extracted, after PCR amplification, 97 exons of 5 desmosomal protein genes [desmoplakin (DSP), desmoglein-2 (DSG2), plakophilin-2 (PKP2), junction plakoglobin (JUP) and desmocollin-2 (DSC2)] were sequenced by Sanger method to analyze gene mutations.Results:Three blood samples of Yunnan sudden death cases and 36 blood samples of relatives were collected. A total of 26 gene mutation sites were detected in 39 blood samples, with a total mutation rate of 26.80% (26/97). There were 13, 5, 3, 3 and 2 mutation sites in DSP, DSG2, PKP2, JUP and DSC2 genes, respectively. Among them, 19 were reported mutations and 7 were new mutations: DSP gene exon 3 c.372G>A, exon 15 c.2090A>G, exon 17 c.2371C>A, exon 24-I c.8458T>G; DSG2 gene exon 8 c.861C>T; PKP2 gene exon 3 c.892C>A, exon 8 c.1725G>T. Three Yunnan sudden death cases and 36 relatives were all carriers of compound gene mutation, and the same person carried 3 - 9 gene mutation sites at the same time.Conclusion:Mutations of ARVC desmosomal protein genes DSP, DSG2, PKP2, JUP and DSC2 exist in Yunnan sudden death cases and their relatives, which may be the genetic background factors of some Yunnan sudden death.

RESUMO
BACKGROUND:Fetal liver stem cel s have the potential to differentiate into hepatocytes and bile duct cel s, and participate in the repair and reconstruction of the liver, which is an important source of hepatocytes. But there are a little amount of fetal liver stem cel s in human body, and how to obtain a certain number of high-purity fetal liver stem cel s is currently a hot research. OBJECTIVE:To construct a siRNA carrier that can effectively inhibit the expression of connexin 43 (Cx43) in rat fetal liver stem cel s, and to investigate the effect of Cx43 inhibition on the proliferation and cel cycle of fetal liver stem cel s cultured in vitro. METHODS:Fetal liver stem cel s were cultured by the suspension culture in vitro, siRNA sequences targeting Cx43 (Cx43-siRNA) and negative control sequence (NC-siRNA) were designed and synthesized. Then, rat fetal liver stem cel s were transferred electrophoretical y and divided into three groups:blank group, NC-siRNA group, Cx43-siRNA group. Real-time PCR and western blot were used to assess the knockdown efficiency. Cel ular proliferation was determined by cel growth curve and cel counting kit-8 assay. The cel cycle was analyzed by flow cytometry. RESULTS AND CONCLUSION:After transfection, the Cx43 gene and protein expression levels were declined dramatical y in the Cx43-siRNA, NC-siRNA and blank groups, and the cel s grew faster. The number of cel s at G0/G1 phase decrease, but the number of cel s in S phase increased. There were significant differences between the groups (P<0.05). Electrophoretic transfer of Cx43-siRNA can promote the proliferation of cultured fetal liver stem cel s and optimize the cel culture.
RESUMO
Objective To evaluate the prophylactic effect of pancreatic duct stent (PPDS),NonSteroid Anti-Inflammtory Drugs (NSAIDs),and joint PPDS and NSAIDs on post endoscopic rectrograde cholangiopancreatography(ERCP) Pancreatitis(PEP) in choledocholithiasis patients.Methods A total of 200 choledocholithiasis patients were randomly divided into 4 groups,prophylactic pancreatic duct stent(PPDS) group (A),NSAIDs group (B),joint PPDS-NSAIDs group (C) and routine ERCP without prevention for PEP(group D).VAS score,levels of amylase in serum and CRP were measured before and 4 h,24 h,48 h after ERCP.Incidences of hyperamylasemia and PEP were observed.Results (1) Incidences of hyperamylasemia 48 h after ERCP were 6% (3/50),6% (3/50) and 4% (2/50) in group A,group B and group C respectively,which were significantly lower than that of group D (11/55) (P < 0.05).(2) Incidences of PEP 48 h after ERCP were both 2% (1/50) in group A and group C,which were lower than that in group D (10%,5/50,P < 0.05).Group B (4%,2/50) was lower than that of group D but there was no statistical significance(P >0.05).(3) VAS scores of all groups at 4 h,24 h and 48 h after the operation were significantly higher than before (P < 0.05).Group B score was significantly lower than that of group D (P < 0.05).Scores of group A and C at 4 h were lower than those of group D (P < 0.05),and those at 24 h and 48 h were also lower but with no statistical significance (P > 0.05).(4) Serum CRP levels at 4 h,24 h and 48 h were significantly higher than those before in each group.Serum CRP levels of group B and C were significantly lower than that of group D at 4 h,24 h and 48 h.Serum CRP level of group A was significantly lower than group D at 4 h,24 h.CRP level at 48 h of group A was lower than that of group D,but there was no statistical significance (P > 0.05).Conclusion Both prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce incidence of hyperamylasemia after ERCP common bile duct lithotomy.Single or joint use of prophylactic pancreatic duct stent can prevent PEP.Furthermore,prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce pain and inflammation after ERCP common bile duct lithotomy.NSAIDs only (Parecoxib Sodium) is more effective than prophylactic pancreatic duct stent only and joint use of both.
RESUMO
Objective To evaluate long-term follow-up for laparoscopic anterior 180° partial fundoplication for gastroesophageal refulx disease (GERD).Methods A total of 48 patients had undergone a laparoscopic anterior 180° partial fundoplication from July 2004 to October 2007.Patients were followed up at 3 months,12 months,3 years,5 years by using a structured questionnaire via phone or e-mail which evaluated symptoms of reflux,dysphagia,side-effects,and overall satisfaction with the clinical outcome.Results Follow-up data were collected from 43 patients,ranging from 60 to 98 months.Postoperative heartburn significantly improved in 37 patients.Normal belching was preserved in 40 patients,and 38 patients were able to eat normally.Thirty nine (90.7%) patients reported a good or excellent result (minimal or no symptoms) at the late follow-up.Two patients underwent laparoscopic anterior 180° partial fundoplication again due to acid reflux at the 12th and 38th month respectively.Conclusion At minimum 5 years followup,laparoscopic anterior 180° partial fundoplication for GERD is effective and lasting,and most patients are satisfied with the outcome.
RESUMO
Objective To investigate the management of complications after laparoscopic adjustable gastric banding (LAGB).Methods The clinical data of 83 obese patients who were treated by LAGB at the Nankai Hospital from September 2005 to June 2011 were retrospectively analyzed.The complications after LAGB were analyzed.The adjustable gastric band was installed under laparoscope so as to form a small gastric pouch with a volume ranged between 20-30 ml.The water pump was fixed in the rectus abdominis anterior sheath under the appendix ensiformis.The gastric band was adjusted according to the changes of the body weight,symptoms after diet and results of imaging examination of upper gastrointestinal tract.Patients were followed up via out-patient examination and phone call till July 2013.Results The incidence of complications of the 83 patients was 44.6% (37/83).Six patients had short-term complications and 31 patients had long-term complications.The short-term complication mainly presented as post-prandial vomiting.The symptoms of 5 patients were relieved by changing of eating habit.The condition of 1 patient was severe,and the symptom was relieved 5 days later after fasting and nutritional support.For the 31 patients with long-term complications,25 were complicated with band erosion into gastric lumen via gastric wall (6 patients were complicated with infection of the water pump site),and they were cured by removal of band laparoscopicly.Ten patients were complicated with water pump-related complications,including 6 with infection of the water pump site and 4 with pump migration.The water pumps of the 4 patients with pump migration were surgically removed.Two patients had band slipping to the stomach.The band was restored to the original place after removing the liquid from the band and reducing the food intake,and then the position of the band in 1 patient was restored to normal,and no change was observed in another patient,and the band was removed laparoscopicly.Conclusions The incidence of complications after LAGB is high,and it increases as the time passes by.Most of the long-term complications after LAGB need to be treated by reoperation.
RESUMO
Objective To evaluate the clinical value and efficacy of prophylactic pancreatic duct stenting for biliary-type stenosis of Oddi sphincter with difficulty cannulation.Methods The present study was a retrospective study of 63 patients with biliary-type stenosis of Oddi sphincter and difficult cannulation.The stent group consisted 30 patients who underwent prophylactic pancreatic duct stenting from February 2010 to February 2011 and the control group included 33 patients who underwent only ERCP without prophylactic pancreatic duct stenting from January 2009 to January 2010.The incidence of postoperative pancreatitis were compared between the two groups.Results The incidence of postoperative pancreatitis of the control group was significantly higher than that of the stent group (P < 0.05).Conclusion For patients with definite diagnosis of biliary-type stenosis of Oddi sphincter and difficult cannulation,prophylactic pancreatic duct stent placement is safe and effective.
RESUMO
Objective To assess the safety and feasibility of hybrid trans-gastric endoscopic and laparoscopic cholecystectomy in a porcine model.Methods A total of 6 pigs underwent hybrid trans-gastric endoscopic and laparoscopic cholecystectomy from July to October,2010 under general anesthesia.The operation time and complications during the procedure were recorded,as well as post-operative changes of eating habits and weight.Animals underwent autopsies on post-operative days(POD)14 for evaluation of infection,abscesses and adhesion.Results All procedures were successfully performed and all dogs survived.There was no severe complication except for hemorrhage in one porcine,which was successfully managed under laparoscopy.The mean operation time was 87mins(ranging from 69-124 mins).After the operation,there was no change in eating habits or weight.At autopsy on POD 14,no abscess or hemorrhage was found.Sites of gastric closure were found to be completely healed.Conclusion The hybrid approach increases the safety of initial gastric puncture and gastric wall incision,simplifies peroral trans-gastric cholecystectomy,and decreases invasiveness of laparoscopic surgery.It is a bridge between laparoscopic and transluminal surgery.
RESUMO
Objective:To investigate the influence of laparoscopic versus open hepatectomy on the stress reaction of patients.MethodsRetrospectively 30 cases who received operation of laparoscopic and open left lateral lobectomy of liver for stones in bile ducts within left lobes of lives were selected form May 2006 to September 2010.The serum level of neutrocytes (N),adrenaline (AD),cortisol (Cor),blood glucose (BG),white blood cell (WBC),Natural killer cell ( NK cell),interleukin-6 (IL-6),C-reactive protein (CRP) were detected preoperatively as well as 24 h,28 h,72 h postoperatively.ResultsAD,Cor reached their peaks after operation,and N,BG,IL-6,CRP reached their peaks in 24 h postoperatively.There were significant difference between O and L groups (P<0.05).NK cell sank to its lowest level in 24 h postoperatively,and there were no significant difference between the two groups (P<0.05).ConclusionLaparoscopic and open left lateral lobectomy of liver are two methods curing stones in bile ducts within left lobes of lives,the former process can result in less stress reaction of patients than the latter.

RESUMO
Objective To evaluate pancreatic duct stenting for acute biliary pancreatitis with difficult endoscopic cannulation. Methods From January 2005 to December 2009, in patients with acute biliary pancreatitis who needed intervention of emergency ERCP, a total of 81 cases were found to be with difficult cannulation and were randomly divided into either treatment group (n = 35 ) to receive pancreatic duct stenting, or control group (n =46) to receive the procedure without pancreatic duct stenting. All patients were treated with same medication, and the pancreatic stents were removed after stabilization at a mean time of 11days after ERCP. All patients were followed up for 3 months after discharging from the hospital. Results There was no significant difference between two groups in regarding of mean age, the time from onset to endoscopy, Glasgow scores and relevant biochemical parameters, but the occurrence of postoperative complications was significantly higher in control group than that of the treatment group ( 17. 39% vs. 5. 71%*, P <0. 01 ). Conclusion Pancreatic duct stenting is a safe and bridging procedure for patients with acute billiary pancreatitis, which can also reduce complications.
RESUMO
Objective To investigate the clinical characteristics and feasibility of laparoscopic repair of giant hiatal hernia. Methods From January 2008 to August 2010, 25 consecutive patients with giant hiatal hernia underwent laparoscopic repair. Crural closure was performed by means of two or three interrupted nonabsorbable sutures plus a tailored PTFE/ePTFE composite mesh. It was patched across the defect and secured to each crura with staples. Laparoscopic fundoplication was performed concomitantly in 16 cases according to the specific conditions of patients. Para-operative clinical parameters were recorded. All patients were routinely followed up. Clinical outcomes were collected and analyzed. Results All laparoscopic surgeries were accomplished successfully. The operating time was 85 -210 minutes (mean, 106 minutes) ,the operative blood loss was 55 - 150 ml( mean, 94 ml) ,the postoperative hospital stay was 4 -21 days( mean, 6.8 days). The symptoms in most cases were adequately relieved after operation. There was no severe postoperative morbidity. After the follow-up period of 3 - 35months ( mean, 13.6 months), the satisfaction rate of surgery was 88%. 4 cases had mild symptom recurrence of acid reflux.Hiatal hernia recurrence occurred in 1 case. Conclusions Laparoscopic repair of giant hiatal hernia is a safe and effective minimally invasive procedure, with the advantages of minimized trauma, quick recovery and reliable effect. The use of a tailored PTFE/ePTFE composite mesh ( Bard CruraSoft Mesh)for giant hiatal hernia proved to be effective in reducing the operation time and technique demands, and the rate of postoperative hernia recurrence, with a very low incidence of mesh-related complications.
