ABSTRACT

Objective:To study and analyse the results of postoperative hemorrhage after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of patients who underwent LPD from May 2011 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. The clinical characteristics of patients, onset time of postoperative hemorrhage, location of postoperative hemorrhage, postoperative biliary fistula, pancreatic fistula, infection and other short-term complications, reoperation and mortality rates were analyzed.Results:Of 356 patients who underwent LPD in this study, there were 200 males and 156 females, aged (58.0±10.5) years. The postoperative complication rate was 33.1% (118/356), the reoperation rate was 6.5% (23/356), and the mortality rate was 2.5% (9/356). The most common complications were postoperative hemorrhage [15.2% (54/356)], pancreatic fistula [14.6%(52/356)] and abdominal infection [13.8%(49/356)]. The onset time of postoperative hemorrhage was usually in the 1st - 14th day, and the highest rate of postoperative hemorrhage was 3.9% (14/356) on the first day after surgery. The postoperative hemorrhage rate then showed a downward trend, but increased again on the 7th day. The extraluminal hemorrhage locations were relatively widely distributed, and the incidence of gastrointestinal anastomotic hemorrhage in patients with intraluminal hemorrhage was the highest [67.9%(19/28)]. Of the 9 patients who died, 7 were related to postoperative bleeding.Conclusions:LPD resulted in a high incidence of complications. Postoperative hemorrhage was a complication that had the greatest impact on short-term recovery of patients. It was also an important cause of reoperation and death. In addition to postoperative bleeding caused by pancreatic fistula, gastrointestinal anastomotic bleeding was also clinically important.

ABSTRACT

Objective:To investigate the clinical efficacy of perihilar surgical techniques for diffuse hepatolithiasis.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 122 patients with diffuse hepatolithiasis who were admitted to Hunan Provincial People's Hospital from January 2010 to December 2015 were collected. There were 39 males and 83 females, aged from 21 to 82 years, with a median age of 51 years. After perihilar hepatectomy, the first, second and third divisions of hepatic ducts were opened longitudinally. Strictures in the bile ducts were relieved by stricturoplasty and internal bile duct anastomosis, and stones were removed by multiple methods under direct vision. After resection of severe atrophic liver segment along the plane of hepatic atrophy or bile duct stricture, T-tube or hepaticojejunos-tomy was used for internal drainage. Observation indicators: (1) surgical situations; (2) stricture relief and stone removal. (3) Follow-up. Follow-up was conducted by Wechat, telephone interview or outpatient examination. Patients were followed up once every 3 months in the postoperative 1 year through liver function and abdominal B-ultrasound examination. Subsequently, liver function and abdominal B-ultrasound were reexamined once a year. Magnetic resonance cholangiopancreato-graphy and computed tomography were performed when cholangitis or stone recurrence was suspected to analyze stone recurrence and patient survival. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical situations: for the 122 patients, the operation time, hepatic portal occlusion time, volume of intraoperative blood loss, duration of postoperative hospital stay were (253±71)minutes, 15 minutes(range, 14?38 minutes), 200 mL(range, 100?1 100 mL), (12±5)days. Postoperative complications occurred to 40 of 122 patients. There were 9 cases of incision infection, 8 cases of bile leakage (5 cases of bile leakage at hepatic section, 3 cases of choledochojejunostomy leakage), 8 cases of septicemia, 7 cases of pleural effusion, 5 cases of abdominal abscess, 3 cases of liver failure, 1 case of biliary bleeding. Some patients had multiple complications. Among the 122 patients, 2 cases died after operation, including 1 case of postoperative liver failure and 1 case of disseminated intravascular coagulation caused by biliary-intestinal anastomotic leakage complicated with sepsis. Patients with bile leakage and abdominal abscess were improved after puncture and drainage under the guidance of B-ultrasound. Patients with cholangiojejunal anastomotic bleeding were embolized through the right hepatic artery. The other complications were improved after conservative treatment. (2) Stricture relief and stone removal: 85 of 88 patients with biliary stricture were relieved, with the stricture relief rate of 96.59%(85/88). Among the 122 patients, 103 cases had stones completely removed and 19 cases had residual stones. The immediate stone clearance rate was 84.43%(103/122). Of the 19 patients with residual stones, choledochoscopy was refused in 3 cases and choledochoscope lithotripsy was performed in 16 cases, of which 7 cases were removed and 9 cases were still residual stones. Of the 122 patients, 110 cases were finally removed stones, 12 cases were eventually residual stones, and the final stone clearance rate was 90.16%(110/122). (3) Follow-up: among the 122 patients, 120 cases including 110 cases with find stone removal and 10 cases with residual stones were followed up for (78±14)months. The 1-, 3, 5-year stone recurrence rates of 120 patients were 0.83%(1/120), 6.67%(8/120), 9.17%(11/120), respectively. The 1-, 3-, 5-year stone recurrence rates of 110 patients with final stone removal were 0, 5.45%(6/110), 5.45%(6/110), respectively. The number of cases with stone recurrence at postoperative 1-, 3- and 5-year of 10 patients with residual stones were 1, 2, 5 cases, respectively. Of 120 patients with follow-up, 1 case died of end-stage liver disease, and the other patients had good survival.Conclusion:Perihilar surgical techniques for diffuse hepatolithiasis is safe and effective.

ABSTRACT

Prosthetic loosening and periprosthetic inflammation, as serious complications after joint replacement surgery, often require the secondary surgery for repair, which is easy to adversely affect the physical/mental health and economic status of patients.Studies have shown that the functional phenotype expressed by macrophages by different stimuli, namely macrophage polarization state, prolonged M1 polarization can lead to the continuation of long-term inflammation, while timely and effective M2 macrophage phenotype will lead to enhanced osteogenesis and tissue remodeling cytokine secretion and subsequent osseointegration, which play a crucial role in the development and outcome of prosthetic loosening and periprosthetic inflammation.The local micro-environment of extracellular matrix (ECM) is an important factor in the activation, migration, proliferation and fusion of macrophages. Researchers have deeply understood it mainly through the crosstalk between surface properties of biomaterials and macrophages. As an effector cell, macro-phages can perform complex spatiotemporal cellular functional responses by sensing the physical and chemical environment (surface topography, wettability, chemical composition, biological proteins) represented by surface properties of biomaterials.This paper summarizes the recent findings on macrophage polarization and material surface properties.

ABSTRACT

Objective@#This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs). @*Materials and Methods@#This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables. @*Results@#The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m2 for PA, 75.9 ± 14.3 mL/m2 for EH, and 77.3 ± 12.8 mL/m2 for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m2 for PA, 30.7 ± 8.1 mL/m2 for EH, and 29.5 ± 7.0 mL/m2 for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m2 for PA, 56.9 ± 12.1 g/m2 for EH, and 44.1 ± 8.9 g/m2 for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosteroneto-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1. @*Conclusion@#Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.

ABSTRACT

Objective To investigate the expression and clinicopathological significance of Bcl-2 and Bax genes in colorectal cancer (CRC) patients complicated with schistosomiasis. Methods The CRC patients receiving surgical treatment in the First Affiliated Hospital of Dali University from June 2016 to June 2020 were recruited as the study subjects, and 30 subjects were randomly sampled from the CRC patients complicated with schistosomiasis (CRC-S group) and 30 subjects were randomly sampled from the CRC patients without schistosomiasis (CRC group) using a random number table method. The cancer specimens were sampled from subjects in the CRC-S and CRC groups, and the peri-cancer specimens were sampled from subjects in the CRC group. The Bcl-2 and Bax expression was quantified in cancer and peri-cancer specimens using a real-time fluorescent quantitative PCR (qPCR) assay and immunohistochemistry at transcriptional and translational levels, and the cell apoptosis was detected in cancer specimens using HE staining. Results A total of 60 subjects were enrolled, including 30 cases in the CRC group and 30 cases in the CRC-S group. There were no significant differences between the two groups in terms of gender distribution (χ2 = 0.271, P > 0.05), mean age (t = -0.596, P > 0.05), tumor growth pattern (χ2 = 0.275, P > 0.05), tumor location (χ2 = 4.008, P > 0.05), tumor invasion depth (χ2 = 0.608, P > 0.05), degree of tumor differentiation (χ2 = 0.364, P > 0.05), or presence of vascular metastasis (χ2 = 1.111, P > 0.05), while significant differences were seen between the two groups in terms of histological type, presence of lymph node metastasis and TMN staging (χ2 = 5.963, 8.297 and 5.711, all P values < 0.05). qPCR assay and immunohistochemistry quantified significantly higher Bcl-2 and Bax expression in cancer specimens from the CRC and CRC-S groups than in the peri-cancer specimens from the CRC group at both translational and transcriptional levels (all P values < 0.05), and higher Bcl-2 and lower Bax expression were seen in the cancer specimens from the CSC-S group than that from the CRC group (all P values < 0.05). In addition, the cell apoptotic rate was significantly greater in the cancer specimens in the CRC group than in the CRC-S group (42.00% vs. 23.35%; χ2 = 41.500, P = 0.000). Conclusion Schistosomiasis may be involved in the development and progression of CRC through affecting Bcl-2 and Bax gene expression in the apoptosis signaling pathway.

ABSTRACT

Objective:To investigate the clinical characteristics and pathogenic mutations of propionic acidemia.Methods:Clinical data of two patients with propionic acidemia admitted to the Obstetrics and Gynecology Hospital of Nanjing Medical University from May 2017 to June 2018 were collected. Genomic DNA was extracted from the peripheral blood of the patients and their parents. Inherited disease panel based on Ion Torrent semiconductor sequencing technology was performed to detect gene mutations, and those with suspected pathogenic mutations were verified by Sanger sequencing. Descriptive statistical analysis was used for data analysis.Results:Case 1 was suspected of sepsis and admitted to the Obstetrics and Gynecology Hospital of Nanjing Medical University due to "drowsiness and milk rejection" on the second day after birth. Tandem mass spectrometry suggested the level of propionyl carnitine and its ratios to acetylcarnitine and free carnitine were increased. Urine gas chromatography-mass spectrometry showed elevated 3-hydroxypropionic acid and methylcitric acid. Genetic analysis revealed that the infant carried c.331C>T (p.R111X)/c.1228C>T (p.R410W) compound heterozygous mutations in the PCCB gene. The infant was diagnosed with propionic acidemia and treated with a special diet with an L-Carnitine supplement but died of sudden coma and vomiting without precipitating factors at three months of age. Case 2 presented with sudden vomiting, drowsiness, and anergia on the admission at five-months old. Tandem mass spectrometry showed increased propionyl carnitine level and its ratios. Compound heterozygous mutations of c.146delG (p.G49EfsX16)/c.1253C>T (p.A418V) in the PCCB gene were identified in the patient, of which c.146delG (p.G49EfsX16) was a de novo mutation and was evaluated as a pathogenic mutation. The patient was on a special diet with an L-Carnitine supplement, but with disobedience. Followed up to the age of three years and eight months, the child was severely underdeveloped. Conclusions:Neonates with clinically suspected sepsis may have propionic acidemia, and tandem mass spectrometry and genetic testing should be performed as soon as possible to confirm or rule out the diagnosis. Further investigations on the pathogenesis and function of the new mutation are still needed.

ABSTRACT

Objective:To study the indications and clinical efficacy of video assisted small incision in treatment of infected pancreatic necrosis.Methods:A retrospective study was conducted on 27 patients with infected pancreatic necrosis treated by video assisted small incision at the Department of Pancreatic and Splenic Surgery, Hunan Provincial People's Hospital, from January 2018 to December 2019. The surgical approach, operation time, intraoperative blood loss, postoperative hospital stay and complications were analysed. Postoperative follow-up was carried out at outpatients’ clinic, and the patient's time to full recovery and long-term complications were studied.Results:The 27 patients successfully underwent the operations. There were 22 males and 5 females, aged (50.6±6.2) years. The treatment results were analyzed according to the different surgical approaches: the retroperitoneal approach group ( n=4); the omental sac approach group (n=14); the intercostal space approach group ( n=2); and the combined approach group ( n=7). The operation time was (85.3±31.6)min. The intraoperative blood loss was 65.0(45.2, 121.4)ml. The postoperative hospital stay was 23.0(12.5, 36.1)days. The incidence of complications (Clavien-Dindo grade Ⅲ and above) was 14.8%(4/27). There were 2 patients in this study who were admitted to the intensive care unit due to postoperative hemorrhage: 1 patient responded well to conservative treatment and the remaining patient required interventional treatment. Another patient because of poor results, underwent debridement by laparotomy 2 weeks after the operation. There was 1 patient who developed grade C pancreatic fistula which was cured by surgical treatment 6 months later. On follow-up, 2 patients developed colonic fistula 2 weeks after surgery and 2 patients gastric fistula 1 week and 3 weeks after surgery. These patients responded to conservative treatment. Conclusion:With proper case selection, video assisted small incision could safely and effectively be used to treat infected pancreatic necrosis.

ABSTRACT

Objective:To study the value of metastatic positivety in lymph nodes group 8a in deciding on extended lymph node dissection in pancreaticoduodenectomy(PD) for pancreatic head cancer.Methods:A retrospective study on 165 patients with pancreatic head cancer treated with PD at the Department of Pancreas and Spleen Surgery, Hepatobiliary Hospital of Hunan Provincial People's Hospital between January 2014 to June 2019 was performed. There were 101 males and 64 females with ages ranging from 38 to 75 (median 57) years. Patients who underwent standard lymph node dissection were included in the standard group ( n=88), and extended lymph node dissection in the extended group ( n=77). These patients were further divided into 4 subgroup. Subgroup A (standard PD in patients with negative nodes in group 8a, n=61), Subgroup B (extended PD in patients with negative nodes in group 8a, n=47), Subgroup C (standard PD in patients with positive nodes in group 8a, n=27), and Subgroup D (extended PD in patients with positive nodes in group 8a, n=30). The operation time, intraoperative blood loss, postoperative survival rates, complications were compared among the groups and subgroups. Results:The operation time and intraoperative blood loss of the standard group were (456.8±30.4) min and (264.28±101.14) ml, respectively, which were significantly lower than the extended group of (507.1±45.7) min and (388.9±155.3) ml (all P<0.05). The incidence of postoperative complications in the extended group (31.2%, 24/77) was significantly higher than that in the standard group (14.8%, 13/88) ( P<0.05). When compared with subgroup B, the cumulative survival rate of patients in subgroup A was not significantly different ( P>0.05). However, the cumulative survival rate of patients in subgroup C was significantly lower than that in subgroup D ( P<0.05). The cumulative survival rate of subgroup A was also significantly better than that of subgroup C ( P<0.05). There was no significant difference in the cumulative survival rates between group B and group D ( P>0.05). Conclusions:PD with extended lymph node dissection improved the survival rates in patients with cancer of the head of the pancreas with positive lymph nodes in group 8a. For these patients, extended lymph node dissection is recommended. With negative lymph nodes in group 8a, standard lymph node dissection is recommended.

ABSTRACT

OBJECTIVE: To analyze the relationship between the neurobehavioral functions of individuals exposed to low-level lead and the levels of serum copper-related proteins glutathione S-transferase M1(GSTM1), hypoxia inducible factor-1 alpha(HIF1α), cyclooxygenase 1(COX1) and metallothionein(MT), and to screen biomarkers for changes in neurobehavioral function caused by occupational lead exposure. METHODS: A total of 194 workers who exposed to low-level lead(lead-exposed group) and 120 workers without lead exposure(control group) were selected from a battery factory as the research subjects by judgment sampling method. The inductively coupled plasma-mass spectrometry was used to determine blood lead levels of the two groups, and the State of Mood Scale(POMS) was investigated to assess the emotional state. The computerized neurobehavioral evaluation system in Chinese version 3(NES-C3) was used to test the neurobehavioral ability index(NAI) of related indicators of learning memory and mental activity. Enzyme-linked immunosorbent assay was used to detect the levels of copper-related protein in serum. After using principal component analysis to extract the principal components of emotional state, learning memory and mental activity, multiple linear regression was used to analyze the influencing factors of neurobehavioral function. RESULTS: The blood lead level of the lead-exposed group was increased [(57.15±11.12) vs(177.86±80.04) μg/L, P<0.01], and the incidence of symptoms such as dizziness, memory loss, sleep disturbance, fatigue, weakness, cold sweats in extremities, cold extremities, tingling of extremities, tingling sensation in the distal extremities, tetany, instability of holding things, metallic taste in the mouth, nausea and vomiting, anorexia, constipation, abdominal distension, abdominal pain, toothache/tooth loosening were increased(all P<0.01) compared with the control group. Meanwhile, the scores of tension-anxiety, depression-dejection, fatigue-inertia, anger-hostility, confusion-bewilderment of POMS were increased(all P<0.01), and the scores of vigor-activity were decreased(P<0.01). The NAI of the lead-exposed individuals in the NES-C3 test of 6 indicators(series addition and subtraction, visual retention, memory scanning, listening to digital breadth, visual simple reaction time, target tracking) were lower than that of the control group(all P<0.01). The serum levels of GSTM1 and HIF1α of the lead-exposed group decreased(all P<0.01), and the COX1 and MT levels increased(all P<0.01) compared with the control group. The serum GSTM1, HIF1α, COX1 and MT of the lead-exposed group were correlated with their emotional state, learning and memory and mental activity to varying degrees(all P<0.05). The results of multiple stepwise linear regression showed that serum COX1 level was an independent influencing factor of emotional state(P<0.01), serum GSTM1, COX1 and lead working years were independent influencing factor of learning and memory(all P<0.05), and work length with lead exposure and alcohol consumption was an independent influencing factor of mental activity(all P<0.05). CONCLUSION: Low-level lead exposure can cause central nervous system symptoms in workers, and the change in neurobehavioral function and serum levels of copper-related proteins GSTM1, HIF1α, COX1 and MT. Serum levels of GSTM1 and COX1 can be used as candidate biomarkers for indicating neurobehavioral function caused by lead exposure.

ABSTRACT

Objective:To explore the characteristics and related factors of unmet needs of nursing care and service for adults with extremely severe and severe intellectual disabilities. Methods:A total of 127 547 adults with extremely severe and severe intellectual disabilities were sampled. Descriptive statistics and multiple response analysis were conducted, and a structural equation model of unmet needs of nursing care and received the services was developed. Results:A total of 26 038 adults with extremely severe and severe intellectual disabilities reported unmet needs of rehabilitation, including nursing care (52.50%), medicine (36.90%), assistive device (20.90%), functional training (19.70%) and surgery (0.80%) respectively. A total of 11 640 adults with extremely severe and severe intellectual disabilities reported received rehabilitation services, including nursing care (49.90%), medicine (36.80%), functional training (19.10%), assistive device (14.10%) and surgery (1.00%) respectively. The structural equation model showed that received nursing care service (main effect = 0.646) and received rehabilitation services (included nursing care) (main effect = 0.014), age (main effect = 0.031), household registration (main effect = 0.015) and educational level (main effect = -0.158) had effects on unmet needs of nursing care (P < 0.001). Conclusion:Adults with extremely severe and severe intellectual disabilities reported unmet needs mainly involved in field of nursing care, and their rehabilitation services mapped to their main needs. It proposed to develop rehabilitation services tailored to their rehabilitation experience, age, socioeconomic status, functional conditions and characteristic of unmet needs, to develop accessible services items and individualized nursing care programs, and to expand the nursing care service supply and coverage of nursing care.

ABSTRACT

Objective:To explore the characteristics and the influential factors of unmet needs and services development of rehabilitation for people with extremely severe hearing disability (PSHDs). Methods:A total of 90 052 PSHDs were included. Multiple response was used to analyze the characteristics of unmet needs and services of rehabilitation. The structural equation model of the received service and unmet needs of PSHDs was developed. Results:The reporting rate of unmet needs of rehabilitation for PSHDs, from high to low, were assistive devices (61.5%), nursing care (24.1%), medicine (23.4%), functional training (17.6%) and surgery (2.5%). The reporting rate of received service for PSHDs, from high to low, were assistive devices (58.3%), nursing care (24.4%), medicine (22.4%), functional training (22.0%) and surgery (2.2%). Structural Equation Model showed that the more services received, the more needs for cochlear implantation surgery and speech therapy (P < 0.001); the better family income situation, the more needs for cochlear implantation surgery (P < 0.001); and age factor had significant effects on the unmet needs of cochlear implantation surgery and speech therapy (P < 0.001). Conclusion:PSHDs reported unmet needs and received services mainly included assistive devices, nursing care, medicine and functional rehabilitation training. Those PSHDs who had received services would report more demand of unmet needs, supposed that improving the accessibility and coverage of services should be emphasized in the development of rehabilitation services. According to ICF model, on the basis of the characteristics of the unmet needs of PSHDs, it proposed to take measures to implement precise rehabilitation services to improve the quality of services.

ABSTRACT

Objective:To analyze the characteristics of unmet needs and services of rehabilitation for people with intellectual disability (PIDs). Methods:A total of 250 654 PIDs had been sampled and administration data of unmet needs and services of rehabilitation at provincial level had been analyzed the characteristics of unmet needs and services of rehabilitation, and the related factors of needs and services were analyzed with Logistic Regression. Results:The rate of unmet needs reported by PIDs from high to low were nursing (47.8%), medicine (37.2%), functional training (26.1%), assistive devices (19.8%) and surgery (1.3%). The PIDs reported received service of rehabilitation, including nursing care (43.5%), medicine (29.3%), functional training (27.2%), assistive devices (19.6%) and surgery (0.8%). Logistic Regression Model showed that age and severity of disabilities significantly affect the reported the unmet needs and received services (P < 0.001). Conclusion:PIDs reported unmet needs mainly involved in the fields of nursing care, medicine and rehabilitation training and therapy. The unmet needs and received services had similar structure. It proposed to develop rehabilitation services tailored to PIDs' intellectual function and adaptive behaviors to develop services items and to deliver individualized and precise services.

ABSTRACT

Objective:To explore the characteristics of unmet needs and services of rehabilitation for people with hearing disability (PHD). Methods:A total of 219 473 PHDs administration data of unmet needs and services of rehabilitation at provincial level were sampled (2019) and analyzed the characteristics of needs and services of rehabilitation with multiple response analysis, and the related factors of needs and services with Logistic regression. Results:There were 47 657 (21.7%) PHDs reported their unmet needs of rehabilitation, from high to low were assistive devices (65.5%), medicine (22.7%), nursing care (19.1%), functional training (16.2%) and surgery (2.2%). There were 34 684 (18.8%) PHDs reported their received services, from high to low were assistive devices (59.8%), medicine (22.5%), functional training (19.7%), nursing care (19.4%) and surgery (1.8%). The logistic regression model showed that age, types of household registration and severities of disabilities related with the reported unmet needs and received services (P < 0.001). Conclusion:PHDs mainly reported unmet needs in the fields of assistive devices, medicine, and rehabilitation training. The reported unmet needs for PHDs had matched the received services structurally. It proposed to use modern science and technology to develop services delivery and to improve accessibility and quality of rehabilitation services.

ABSTRACT

Objective:To analyze the characteristics of needs and development of rehabilitation services for people with visual disability (PVD). Methods:A total of 241 865 PVDs administration data of unmet needs and services of rehabilitation at provincial level were sampled and analyzed the characteristics of needs and services of rehabilitation, and the related factors of needs and services. Results:There were 50 882 (21.0%) PVDs reported their needs of rehabilitation, from high to low were assistive devices (56.5%), medicine (29.0%), nursing care (24.6%), functional training (15.5%), and surgery (4.2%). There were 43 492 (18.0%) PVDs reported their received services of rehabilitation, from high to low were assistive devices (55.0%), medicine (21.6 %), nursing care (20.8%), functional training (20.7%) and surgery (2.3%). The logistic regression model showed that severities of disabilities related with the reported unmet needs and received services (P < 0.001). Conclusion:PVDs reported unmet needs mainly in the fields of assistive devices, medicine, and nursing care. There is match structure of unmet needs and received services. It is important to provide accessible information environment. Information and communication technology (ICT) are proposed to assistive technology services for PVDs to enhance their capacity of information acquisition and to promote their participations.

ABSTRACT

Objective@#To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen′s pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD) .@*Methods@#Clinical data of 116 consecutive patients who underwent LPD using Chen′s pancreaticojejunostomy technique in Hunan Provincial People′s Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen′s pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed.@*Results@#All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes) . The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2% (13/116) of cases had postoperative pancreatic fistula (POPF) , including 10.3% (12/116) of biochemical fistula and 0.9% (1/116) of grade B POPF, no grade C POPF occurred; 10.3% (12/116) had gastrojejunal anastomotic bleeding; 3.4% (4/116) had hepaticojejunal anastomotic fistula; 3.4% (4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1% (14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7% (2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery.@*Conclusions@#Chen′s pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.
