Objective:To investigate the clinical effect of proper management of inferior pancreaticoduodenal artery (IPDA) in laparoscopic pancreaticoduodenectomy (LPD).Methods:This is a retrospective case series study. The clinical and pathological data of 70 patients who received LPD due to pancreatic head tumors, periampullary tumors, or distal common bile duct tumors in the Pancreatic Center of the Second Clinical College of Guangzhou University of Chinese Medicine from January to December 2022 were retrospectively collected. There were 47 males(67.1%) and 23 females(32.9%),aged (59.9±12.8)years(range:13 to 87 years).The procedure of IPDA exposure was as follows:a middle approach was utilized to expose the right half of superior mesenteric artery(SMA) and its right branches between the SMA and superior mesenteric vein(SMV) in superior colonic region. In the subcolonic region,SMA trunk exposure via dissection along the jejunal artery from feet to head and identification the association between IPDA and jejunal artery were prior to IPDA root ligation and dissection. The safety and efficacy of intraoperative IPDA handling were assessed based on surgical videos. Follow-up was carried out in outpatient clinic or by telephone, and outpatient follow-up was conducted once every 1 to 3 months after surgery.Results:The percentage of total LPD was 98.6%(69/70),with all patients achieving R0 resection. Nine cases(12.9%) were involved in combined vascular resection and reconstruction,with 1 case (1.4%) requiring additional upper abdominal incision for vascular and gastrointestinal reconstruction,while the remaining eight cases (11.4%) were completed laparoscopically. The operative time was (432.7±115.4)minutes(range:282 to 727 minutes), and the blood loss was (140.0±125.7)ml(range:20 to 800 ml). Only two patients(2.9%) received fresh frozen plasma transfusion,with an average volume of 650 ml. Reliable ligation and safe handling of the IPDA were achieved in 91.4%(64/70) of cases, with 8.6%(6/70) suffering from IPDA injury-related bleeding. No one was converted to opened surgery. Pathologically,the mean tumor size was (3.3±1.6)cm (range:1 to 7 cm),and the mean number of harvested lymph nodes was 17.0±7.3(range:0 to 46). Lymph node metastasis was observed in 13 cases (18.6%). Five cases (13.2%) developed grade B pancreatic fistula,while no grade C pancreatic fistula occurred. Other complications included bile leakage in one case(1.4%),delayed gastric emptying in two cases(2.9%), lymphatic leakage in 2 cases(2.9%),intra-abdominal infection in 9 cases(12.9%),and fat liquefaction of surgical incision in 1 case(1.4%). Two cases(2.9%) experienced postoperative intra-abdominal bleeding,one due to mesangial bleeding of lesser curvature of the stomach and the other due to oozing from the hepatic arterial sheath. These bleeding events were not concerned with IPDA. The average length of postoperative hospital stay was (15.2±4.6)days(range:9 to 28 days).Conclusion:Proper intraoperative management of IPDA in LPD might reduce IPDA-related bleeding during and after surgery and improve the safety of LPD.

Objective To understand the management status of emergency and life support medical equipment in town-ship health centers in Huazhou City,providing a reference for improving emergency service levels in grassroots medical institu-tions.Methods A convenience sampling method was used to conduct a questionnaire survey of physicians,nurses,medical technicians,public health personnel,and administrative and logistical staff in 24 township health centers in Huazhou City.The survey focused on seven aspects:procurement and configuration,upgrades,operational use,maintenance,emergency handling,management systems,and quality assessment and monitoring.Results Training on emergency and life support equipment was generally adequate in Huazhou City(65.2％).Health centers in northern and central Huazhou performed better than those in the urban and southern areas regarding equipment training,emergency handling procedures for equipment failures,regular emergency drills,meeting clinical treatment needs,management system completeness,routine maintenance and inspections,and regular quality assessments.Factor analysis revealed significant issues with equipment aging and quality in urban township health cen-ters,while northern township health centers urgently needed life-sustaining and therapeutic equipment.Conclusion There are regional disparities in the management levels of emergency and life support medical equipment in township health centers in Hua-zhou City.It is recommended to enhance the overall quality of personnel in township health centers,optimize"effective training"for staff,and improve annual management plans to further elevate grassroots emergency service capabilities.

Pancreaticoduodenectomy is one of the most difficult abdominal operations, and the difficulty in resection and complicated digestive tract reconstruction have brought great challenges for surgeons. At present, laparoscopic pancreaticoduodenectomy has been widely used in clinical practice, and compared with traditional 2D laparoscopy, 3D laparoscopy has the features of high magnification, high definition, and three-dimensional vision, which enables surgeons to see more clearly and operate more accurately, and thus it has great potential to be widely used in pancreaticoduodenectomy.

Objective:To study the preliminary clinical results of the No-touch technique in laparoscopic pancreaticoduodenectomy for pancreatic head cancer.Methods:A retrospective analysis was consulted on 11 patients who underwent laparoscopic pancreaticoduodenectomy for pancreatic head cancer at the Pancreas Center of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2019 to April 2020. There were 5 males and 6 females, with a Mean±SD age of (63.6±12.2) years. Preoperative evaluation showed all patients were diagnosed to have resectable pancreatic head carcinoma with no local invasion into adjacent arteries and veins, and without metastasis. The surgical strategy consisted of no initial Kocher manoeuvre with no flipping or pulling of the pancreaticoduodenal area. Through unwinding of the pancreatic uncinate process, the pancreatic blood vessels, nerves and lymphatic vessels were completely detached to isolate the tumor. Finally, the pancreaticoduodenal area was totally resected and the digestive tract was reconstructed using the Child’s method. The operation time, intraoperative blood loss, postoperative complications, postoperative pathology and follow-up data of the patients were evaluated.Results:All patients completed the laparoscopic operation without any need for conversion to laparotomy. The operation time of the 11 patients was (422.2±102.2) min, and the bleeding volume was (102.7±65.4) ml. There were 2 patients who developed pancreatic fistula, with 1 patient having a biochemical fistula and 1 patient a grade B fistula. There was no grade C fistula. Other complications included 1 patient with delayed gastric emptying. There were no biliary fistula, no postoperative abdominal bleeding, and no perioperative death. Postoperative pathology showed 6 patients had lymph node metastases, with a positive lymph nodes rate of (4.8±4.4)%. All patients had R 0 resection. The follow-up survival data of the 11 patients showed one patient to develop intrahepatic metastasis 1 month after operation and he died 9 months after operation. Another patient developed liver metastases 2 months after operation. The remaining patients were tumor-free. Conclusion:Laparoscopic pancreaticoduodenectomy using the No-touch isolation and resection technique could achieve complete resection of tumors, and it can safely and effectively be applied to patients with pancreatic head cancer.

Objective:To examine the surgical approach, practical cognition as well as clinical effect of the orthotopic resection for laparoscopic pancreatoduodenectomy(OLPD).Methods:From March 2019 to December 2019, 32 cases were treated with laparoscopic pancreatoduodenectomy (LPD) in a novel approach without mobilization of pancreatoduodenum in Pancreas Center of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine.There were 16 male patients and 16 female patients.The mean age was (64.8±9.5) years old.Body mass index was 14.9 to 31.0 kg/m 2.All patients were diagnosed as ampullary or pancreatic head tumors and were not unresectable cases.In the surgical strategy, Kocher′s dissociation, turning and pulling of the pancreaticoduodenal region, was not performed first.Anatomy in situ, separation of vessels which enter and exit from pancreas, separation of lymphatics and isolation of tumors were carried out in priority through the combined middle and left posterior approaches.Finally, the pancreatic head and duodenum region was mobilized and the entire resection of pancreas in situ was carried out.Digestive tract reconstruction was performed through Child method. Results:Postoperative pathology showed that 27 cases were pancreatic or ampullary malignant tumors and five cases were benign tumors among 32 patients.The operative time was (357.3±64.3) minutes.The diameter of pancreatic ducts was (3.0±1.0) mm. The pancreas of 20 cases (62.5%) were soft. Five patients suffered from pancreatic fistula (Grade B) and one patient suffered from intra-abdominal hemorrhage postoperatively.No other complications like pancreatic fistula (Grade C) or biliary fistula delayed gastric emptying or mortality were encountered.The postoperative hospital day was (13.7±3.6) days.Conclusions:Combining the multi-angle of the laparoscopic approaches and excising the pancreaticoduodenal specimen in situ, OLPD is a kind of surgical method which can realize the concept of no touch tumor surgery.Patients who undergo the OLPD can receive better treatments and results.

OBJECTIVE: To establish the norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents. METHODS: Using a multistage stratified sampling method, we conducted a large-scale epidemiological investigation among 15 066 urban residents sampled from 6 regions in China, including Tianjin City (north China), Guangdong Province (south China), Anhui Province (central south China), Sichuan Province (southwest China), Lanzhou City (northwest China) and Harbin City (northeast China). The mean, percentile and threshold norms were established based on the characteristics of SHMS V1.0 scores for Chinese urban residents. RESULTS: The mean and percentile norms of total, physical, mental and social sub-health of Chinese urban residents were established according to gender and different age groups (14-19, 20-29, 30-49, 50-64 and ≥65 years). The threshold norms of SHMS V1.0 divided 5 health states, namely disease, severe sub-health, moderate subhealth, mild sub-health and healthy states according to the ± and ±0.5 of the converted scores. CONCLUSIONS The norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents were established, which provides a reference for rapid screening and diagnosis of sub-health status in Chinese urban residents and facilitates further study of the prevalence and contributing factors of sub-health.

OBJECTIVE: To explore the direct relationship between personality (PN) and sub-health status (SHS) and their indirect association mediated by frustration quotient (FQ) and stress event (SE). METHODS: A multiple-stage stratified sampling method was used to choose the participants, and a total of 4517 eligible urban residents were selected.ANCOVA was used to analyze the independent association between personality and SHS after adjusting the demographic characteristics and lifestyle.A structural equation model was used to analyze the associations among personality, FQ, SE and SHS.Bootstrap method was used to test the direct and indirect association between personality and SHS. RESULTS: Personality was independently associated with total sub-health (=75.913, < 0.001), physical sub-health (=23.618, < 0.001), mental sub-health (=101.993, < 0.001) and social sub-health (=48.757, < 0.001).The urban residents with the personalities characterized by anger suppression, anxiety and irritability, and impatience and competitiveness had significantly lower health scores than those with a mature and steady personality ( < 0.05).Personality was associated with FQ and SE, and the indirect association between personality and physical sub-health was mainly mediated by FQ and SE (β=-0.110).Personality showed more a direct association (β=-0.172) with mental sub-health and a slightly less indirect association (β=-0.126) with mental sub-health.Personality showed a more indirect association (β=-0.113) with social SHS and slightly less direct association (β=-0.082) with social sub-health. CONCLUSIONS A mature and steady personality may help to promote the general health level, while the personalities of anger suppression, anxiety and irritability, impatience and competitiveness can be associated with the occurrence of sub-health.Building a mature and steady personality has positive effects on the health in general of an individual.
