Objective To evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. Methods Eight publications on the necessity of gastrointestinal decompression after gastrecomy were colleted, data on recovery time of gastrointestinal function and hospital stay, complications,and motality were Meta-analyzed using fixed effect model and random effect model. Results Eight randomized trails including 975 patients were qualified and included in this study. The differences in time to oral intake ( WMD =0. 61, 95% CI: 0. 17 - 1.05, P ＜ 0. 05 ) and hospital stay ( WMD = 1.20, 95% CI:0. 05 -2. 36, P ＜ 0. 05 ) between the decompression group and non-decompression group were statistically significant, but the difference in time to flatus (WMD = 0. 31,95% CI: -0. 07- 0. 69, P ＞ 0. 05 ) was not significant. There were no significant differences in complications such as nausea and vomiting ( OR = 1.43,95% CI: 0. 61 - 3.31, P ＞ 0. 05 ), pulmonary infection and atelectasis ( OR = 1.43, 95 % CI: 0. 82 - 2. 49,P＞0.05), anastomotic leakage (OR = 1.17, 95%CI: 0.54-2.49, P ＞0.05), abdominal abscess ( OR = 1.08, 95% CI: 0. 50 - 2. 34, P ＞ 0. 05 ), wound dehiscence ( OR = 1.47, 95% CI: 0. 43 - 4. 95,P ＞ 0. 05 ) between the two groups, except for fever ( OR = 1.76, 95% CI: 1.11 - 2. 78, P ＜ 0. 05 ), which was found more frequent in decompression group than in non-decompression group. Conclusions Routine gastrointestinal decompression after gastrectomy was not conductive to the recovery of gastrointestinal function, and could not reduce the incidence of postoperative complications. Postoperative GI decompression increased fever incidence rate and prolonged hospital stay.

Objective To observe the effects of anisodamine on levels of neurotensin in the plasma and lung homogenate during acute lung injury in rats after brain trauma.Methods The level of neurotensin in the plasma and lung organizes after brain trauma and that after administration with anisodamine were determined by radioimmunoassay(RIA).Results Level of neurotensin in the plasma and lung homogenate of rat with brain trauma was obviously higher than that in normal control group but significantly lower than that in anisodamine group.Conclusion Increase of neurotensin in the plasma and lung homogenate may be due to causing lung injury after brain trauma.Anisodamine can exert protective effect on acute brain injury by reducing level of neurotensin in in the plasma and lung homogenate.

Objective To evaluate the association between hemoglobin concentration and stroke severity on admission in ischemic stroke without diabetes. Methods Based on the China National Stroke Registry,the information of acute stroke patients were collected by trained research coordinators and investigators with the methods of review clinical records or interview. Demography, disease history, behavior and habits, hemoglobin concentration,and NIHSS score on admission were collected in this study. The iIncluded patients with the integri?ty of the information of non diabetes,3 h to the hospital,no gastrointestinal bleeding and Hb concentration and NIHSS score at admission. Hemoglobin concentration was classed according to quintiles and the outcome was grouped into ≤3 and >3 groups. The method of logistic regression was used to explore the association between hemoglobin and NIHSS. Results A total of 1 419 individuals was included in this study,including 883 males and 536 females. The mean age was 67. 24±12. 46 years old and the proportion of NIHSS>3 was 67. 51% (958/1419). With respect to non?minor stroke (NIHSS>3),the odds rations and 95% confident intervals of patients with hemoglobin ≤121. 0 g/L(Q1),>122. 1-≤132. 0 g/L(Q2),>141. 0-≤152. 0 g/L(Q4),≥152. 1 g/L (Q5) were 1. 84(95%CI 1. 21-2. 79,P=0. 004),1. 24(95%CI 0. 83-1. 86,P=0. 294),1. 32(95%CI 0. 88-1. 96,P=0. 178) ,1. 52( 95%CI 1. 01-2. 28,P=0. 044) respectively,compared with hemoglobin between 132. 0 and 141. 0 g/L( Q3) . Conclusion Stroke severity is associated with lower and higher hemoglobin concentration in acute ischemic stroke without diabetes.

Objective To investigate the prognosis of patients with Kawasaki's disease complicated with coronary artery lesion and to provide evidence for diagnosis and treatment of these patients. Methods This study was conducted during January 2002 to June 2007. All patients diagnosed as Kawasaki's disease complicated with coronary artery lesions were from the Affiliated Hospital of Guilin Medical College, the Second People's Hospital of Guangxi Province and Guilin Women and Childrens' Hospital. All cases were echocardiogram examined in month 3, 6, 12, 24 and 36 in the purpose of observing the morphology of coronary artery. The study subjects were re-categorized to the groups of mild, moderate dilatation of coronary artery and giant coronary aneurysm, based on the severity of coronary artery lesion. The results of these results of the three groups were compared. Results Eighty-four cases in the mild group, 27 cases in the moderate group and 8 cases in the giant coronary aneurysm. The recovery cases were 23 (27%), 3 (11%) and 0 in the 3 groups respectively at month 3. The above numbers were 44 (52%), 8 (30%) and 0 respectively at month 6.The numbers were 69(82%), 13 (48%) and 1 (13%) at month 12. The numbers were 78 (93%), 19 (70%), 3 (38%) at month 24. The numbers were 82(98%), 20(74%) and 4(50%) at month 36. Thirteen patients were treated with adenosine-triphosphate (ATP) stress echocardiography examiantion, 5 patients were evaluated by coronary angiography,and 4 patients were tested by 64-slice CT coronary reconstruction. Part of the patients were found to have coronary stenosis or occlusion. Conclusion Patients of Kawasaki's disease often have concurrent coronary artery lesions. Patients with mild dilatation of the coronary artery are the most commonly seen and have the best prognosis. On the contrast, patients with giant coronary aneurysm are the lest common situation and is the worst in prognosis. Part of them will develop coronary artery stenosis or occlusion in late stage which may lead to ischemic heart disease. We should stress on close follow-up of patients with Kawasaki's disease complicated with coronary artery lesion. Appropriate and timely treatment will increase their clinical outcomes.

Objective:To compare the postoperative anorectal and urogenital function in patients undergoing Da Vinci robot vs laparoscopic total mesorectal excision (TME) for middle and low rectal cancer.Methods:A prospective controlled study was conducted to analyze the clinical data of 120 patients with middle and low rectal cancer receiving low anterior resection (Dixon procedure) at the Department of Gastrointestinal Surgery, Guizhou Provincial People's Hospital from Jun 2020 to Oct 2022, including 65 patients in the laparoscopic surgery group and 55 patients in the robotic surgery group.All patients underwent colonoscopy and pelvic MRI, and the distance of the tumor from the anal margin was less than 10 cm.The clinical data of the patients were collected and followed up by questionnaire at 12 months after operation. The anal defecation function was assessed by Wexner constipation score and low anterior resection syndrome scale (LARS).The urinary function was measured by International Prostate Symptom Score (IPSS) and International Advisory Committee on Urinary Incontinence Lower Urinary Tract Symptom Scale (ICIQ-MLUTS/ ICIQ-FluTS).Reproductive function was valued by International Index of Erectile Function (IIEF-5 score) was used for male function and the sexual function index (FIFS-19) for females.Results:The postoperative anal defecation function in robotic group was better than that of the laparoscopic group, and the LARS score was (4.3±2.2) vs. (9.8±1.5), t=9.151, P=0.038.There was no serious urinary dysfunction in neither groups. The robot group had a certain advantage in the protection of male urinary function [ICIQ-MLUTS, (1.8±5.8) vs. (13.8±4.9), t=4.128, P=0.038], while there was no significant difference in the female urinary function between the two groups .ICIQ-FLUTS [(-0.3±1.0) vs. (-0.2±0.9), t=0.015, P=0.844].There was no significant difference in reproductive function between the two groups, IIEF-5 score [(-13.4±2.7) vs. (-11.7±3.4), t=0.35, P=0.615]. FIFS-19 [(-5.2±4.6) vs. (-10.5±6.4), t=4.128, P=0.254]. Conclusions:Compared with laparoscopic surgery, robotic surgery has a better possibility of anal defecation after middle-low rectal cancer surgery. The robotic group has certain advantages in male urinary function protection, and the two surgical methods have similar effects on reproductive function protection.

Objective:To study the relation ship between the branch patterns of inferior mesenteric artery (IMA) and imaging pelvic measurement parameters for anastomotic leakage (AL) after anterior resection (AR) of rectal cancer.Methods:Five hundred thirty-four patient were enrolled from Jan 2008 to Dec 2018 at the General Surgery Department of Guizhou Provincial People's Hospital. The AL related imaging risk factors were analyzed by chi-square test or Fisher's exact test.Results:AL was found in 36 (6.7%) patients. AL related mortality rate was 11.1% (4/36) compared to 0.4% (2/498) in those without the complications of no AL cases ( P<0.001). Seven pelvic imaging measurement results were attained in 412 patients including anteroposterior diameter of the inlet of the pelvis, anteroposterior diameter of the outlet of the pelvis, upper edge of the symphysis pubis to the tip of the coccyx, sacrococcygeal distance angle from the lower edge of the pubis to the upper edge of the pubis to the sacral promontory, distance between the ischial spines and that of ischial tuberosity. Univariate analysis showed that there was no significant relationship between the above 7 pelvic measurement parameters and the occurrence of AL (all P>0.05). There was no significant relationship between branch patterns of IMA and AL after rectal cancer surgery ( P=0.712). Conclusion:AL as a severe postoperative complication in rectal cancer patients undergoing AR procedure were caused by multiple factors. Neither IMA branch patters nor pelvic imaging measurement seem to be related to the occurrence of AL after AR for rectal cancer.

Objective:To assess the effect of ambient temperature on mortalities of ischemic stroke and hemorrhagic stroke in Beijing, China.Methods:The stroke mortality surveillance data and meteorological data in Beijing from January 1, 2014 to December 31, 2019 were collected. Distributed lag nonlinear models were used to estimate the cumulative effects of ambient temperature on stroke mortality, including ischemic stroke and hemorrhagic stroke after adjusting for temporal trend, day of week, air pollution, and relative humidity. Stratified analysis was conducted to evaluate whether sex and age modify the effect.Results:From 2014 to 2019, a total of 99 222 stroke deaths occurred in Beijing, including 69 327 ischemic stroke deaths, 24 954 hemorrhagic stroke deaths, and 4 941 unspecific stroke deaths. Using distributed lag nonlinear models, it was found the effect of temperature on stroke mortality was nonlinear and lagged. The ischemic stroke mortality risk analysis shows that with the minimum ambient temperature (MMT) for mortality (10.0 ℃) as reference, the effect of extreme low temperature (-6.2 ℃) was lagged and the relative risk ( RR) was highest at lag 0-21 days ( RR=1.26, 95% CI:1.04-1.51). The effect of extreme high temperature occurred with a lag of 0-3 days, and the cumulative RR value was 2.13 (95% CI: 1.72-2.62) at lag 0-14 days. The hemorrhagic stroke mortality risk analysis shows that with the MMT for mortality (28.0 ℃) as reference, the RR of extreme low temperature on stroke mortality was highest at lag 0-21 days ( RR=2.14, 95% CI: 1.23-3.70), and the effect of extreme high ambient temperature was short and only has statistical significance in the cumulative effect with a lag of 0-3 days ( RR=1.14, 95% CI: 1.01-1.28). Stratified analysis revealed that the effects of extreme and moderate low ambient temperature on hemorrhagic stroke death were higher in women compared to men, and the difference is statistically significant. Extreme high ambient temperature might increase the risk of ischemic stroke deaths in populations of different genders and age groups. Conclusions:The effect of low ambient temperature on ischemic stroke mortality was lagged, and the effect on hemorrhagic stroke was persistent. The effect of high ambient temperature on ischemic stroke mortality was persistent, but more transient on hemorrhagic stroke mortality. Sex and age might modify the effect of ambient temperature on stroke mortality.

Objective:To quantify cerebral cortical and deep gray matter atrophy in patients with multiple sclerosis (MS) and explore its correlation with impairment in domains of cognitive function.Methods:Twenty patients with MS and 16 healthy controls (HC) matched for age, sex, and education level were included. Using FreeSurfer software, based on 3D-MRI technology, the differences in cortical thickness and deep gray matter volume between the two groups were comparatively analyzed. A neuropsychological scale that included six domains of cognitive function was scored on both study groups to analyze the correlation between cortical thickness and volume of deep gray matter in MS patients with impairment in cognitive function domains.Results:Impairment in domains of cognitive function: cognitive impairment was present in 60% MS patients in this study, mainly manifesting as impairment of verbal memory, verbal fluency, visuospatial memory, and information processing speed function (all P<0.05). Of these, the majority had impaired visuospatial memory function (55.0%), and the least number of patients had impaired information processing speed (15.0%). Changes in cortical thickness: compared with the HC group, the MS group showed that cortical atrophy was mainly concentrated in the frontoparietal region, including significant thinning of cortical thickness in the left inferior parietal gyrus, right superior frontal gyrus, and the right superior parietal gyrus (all P<0.05). Among them, atrophy of the left inferior parietal gyrus was significantly positively correlated with the impairment of verbal memory, verbal fluency, and information processing speed (all P<0.05). There was a significant positive correlation between the right superior frontal gyrus atrophy and verbal memory, verbal fluency, and visuospatial memory impairment (all P<0.05). Changes in deep gray matter volume: compared with the HC group, deep gray matter volume in the MS group decreased significantly in the bilateral thalamus, bilateral putamen, bilateral pallidum (all P<0.01), and right nucleus accumbens ( P<0.05). Among them, left thalamus atrophy was significantly positively correlated with visuospatial memory impairment ( r=0.45, P=0.046), and left putamen atrophy was both significantly positively correlated with visuospatial memory ( r=0.45, P=0.047) and information processing speed impairment ( r=0.50, P=0.026). Conclusions:Early structural brain changes in MS are dominated by gray matter atrophy. Deep gray matter is more prominent than cortical atrophy.

OBJECTIVETo understand provider initiated HIV testing and counseling (PITC) in a region with high HIV/AIDS epidemic in China, and analyze its effect to early detection of HIV infections.

METHODSBetween January and December, 2013, 37 county level medical institutions were selected as the study sites, among which, 19 were public medical institutions and 18 were private institutions. According to the related regulation, procedures and contents of PITC, the study was implemented among outpatients and inpatients who seek for doctors in these medical institutions and PITC were provided for them. The 'Individual Investigation Form' was used to record the information and high-risky factors, and the respondents were taken venous blood and given HIV screening and confirmation. All available serum samples of newly found HIV/AIDS cases were tested using the BED HIV Incidence Capture Enzyme Immunoassay (BED-CEIA) to differentiate the long-term infections and new infections (early detected infections). Chi-square analysis was used to compare the differences of characteristics of newly infected patients.

RESULTSBetween January and December, 2013, a total of 37 medical institutions provided PITC. 55 164 person times were received HIV screening, among which 658 were HIV positive, and 598 were confirmed to be HIV positive. The 598 cases were all provided transferring service. The differences of age, marital status, education levels, transmission routes and testing institutions had statistical significance to early detection (χ(2) equals to 23.54, 10.50, 17.96, 21.22 and 4.80; P equals to < 0.001, 0.005, < 0.001, < 0.001 and 0.029, respectively). And the early detection proportions among patients aged from 20 to 29 and from 50 to 84 were 47.1% (114/242) and 42.1% (24/57), respectively; the proportions among single and married patients were 37.8% (56/148) and 38.9% (143/368), respectively; the proportion among patients with high school education levels were 42.6% (26/61); the proportion among patients transmitted by fixed heterosexual sexual partners was 46.0% (86/187); the proportion among private hospitals was 40.3% (58/144).

CONCLUSIONA certain proportion of HIV infections were early detected by PITC in this region. The HIV early detection proportions among specific age group and population with spouse/fixed sexual partners were relatively high.
