Objective To investigate the effects of Huoxue yiqi runchang decoction in the treatment of chronic intractable constipation in colonic dynamics.Methods 68 cases patients of chronic obstinate functional constipation from October 2013 to June 2016 in linhai traditional chinese medicine hospital were selected and randomly divided into two groups,34 cases in each group,two groups received reasonable diet and lifestyle guidance and general treatment, and the control group received oral mosapride,and the experiment group received more with Huoxue yiqi runchang decoction.Levels of serum MTL and SP,the score of line Wexner constipation and GIQLI,colon motility examination,and clinical efficacy were compared.Results Compared with before treatment,levels of serum MTL and SP in two groups were increased (P<0.05),score of Wexner constipation decreased (P<0.05),and score of GIQLI increased (P<0.05),and transmission time of RCTT,LCTT and RSTT decreased (P<0.05).Compared with the control group,levels of serum MTL and SP in the experiment group were higher,score of Wexner constipation were lower (P<0.05),score of GIQLI were higher(P<0.05), and transmission time of RCTT,LCTT and RSTT was lower ( P <0.05 ) , and the clinical efficacy was higher ( P <0.05 ) .Conclusion Huoxue yiqi runchang decoction can improve clinical symptoms in patients with chronic constipation, and enhance the gastrointestinal motility,and improve the clinical efficacy.

Objective To understand the specimen source of clinical isolated Acinetobacter(A.)baumannii and its department distribution and drug resistance in order to guide the clinical standardized medication for preventing the drug resistance increase. Methods The drug resistance of A.baumannii was monitored by using the unified scheme,materials,methods and criteria (CLSI2010).Results Among 579 strains of A.Baumannii,39 strains(2.2%)were isolated in 2011,187 strains(10.5%)were isola-ted in 2012 and 353 strains(15.4%)were isolated in 2013.In the department distribution,271 strains were isolated from ICU and 104 strains from the department of respiratory medicine.In the positive isolation rates of various specimens,the positive rate was dominated by the sputum specimen(5.55%),followed by wound secretion and pus.The antibacterial susceptibility tests showed that A.baumannii had lowest resistance to cefoperazone/sulbactam(40.1%),which could be used as the drug of first choice.Con-clusion A.baumannii has the higher resistance to many kinds of antibacterial drugs.The drug resistance monitoring of A.bauman-nii should be strengthened in clinc and antibacterial drugs should be selected and used rationally.

Objective To explore the effect of lactulose oral solution in the treatment of patients with chronic functional constipation and its influence on the level of MTL and NO.Methods 54 cases of patients were selected with primary glaucoma who were treated in our hospital from June 2013 to October 2014 as research objective,and they were randomly divided into research group(29 cases)and control group(25 cases)according to the number table method.All of the patients were given treatment as diet adjusting,defecating exercise and so on.The research group got extra treatment as taking lactulose oral solution 10 g,2 to 3 times per day,for 6 weeks.Results MTL in the research group before treatment was 203.71ng/mL,and it was 371.03ng/mL after treatment for 6 weeks,there was statistically significance on difference of MTL levels between before treatment and after treatment(P <0.05).NO in the research group before treatment was 120.52ng/mL,andit was 69.01ng/mL after treatment for 6 weeks,there was statistically significance on difference of NO levels between before treatment and after treatment(P <0.05).MTL in the control group before treatment was 206.21ng/mL,which was 279ng/mL after treatment for 6 weeks,there was statistically significance on difference of MTL levels between before treatment and after treatment(P <0.05).NO in the control group before treatment was 123.92ng/mL,which was 98.75ng/mL after treatment for 6 weeks,there was statistically significance on difference of NO levels between before treatment and after treatment(P <0.05 ).MTL levels in the research group after treatment was higher than that in the control group when NO levels was lower than that in the control group,the difference was statistically significant(P <0.05).Conclusion Lactulose can improve the secretion of gastrointestinal hormones in plasma such as promoting the secretion of MTL and reducing the synthesis of NO.

Objective:To explore the clinical features, diagnosis, treatment and prognosis of rectal neuroendocrine tumor with lymphatic metastasis.Method:There were 153 case who were diagnosed with RNET, among them, there were 10 patients(6.5%) with lymphatic metastasis in Affiliated Union Hospital, Tongji Medical College, Huazhong University of Science & Technology from January 2012 to December 2020, including 4 males and 6 females, aged from 32 to 71 years old, and the median age was 56.5 years.Results:Of the 10 patients, 3 had tumors < 1 cm in diameter, 4 had 1 to 2 cm, and 3 had > 2 cm. Preoperative CT examination was performed in 10 patients, of which 9 suggested lymphatic metastasis; preoperative MRI examination was performed in 7 patients, of which 6 suggested lymphatic metastasis. All patients were received radical resection, in which Miles operation was performed in 2 cases, Dixon operation in 6 cases, and additional Dixon operation after endoscopic submucosal dissection in 2 cases.All patients were followed up for 51 months (ranged from 14 to 118 months). Nine patients had no recurrence or metastasis, and one patient had abdominal metastasis 40 months after surgery and died after 31 months of comprehensive treatment.Conclusions:Lymphatic metastasis is rare in rectal neuroendocrine tumor. Imaging examination has important reference value for judging the status of lymphatic metastasis. For rectal neuroendocrine tumor with lymphatic metastasis, radical resection is effective.

Objective:To investigate the clinicopathological features and prognosis of patients with gastric gastrointestinal stromal tumor (GIST) combined with digestive tract cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 163 patients with gastric GIST who were admitted to the Union Hospital admitted to Tongji Medical College of Huazhong University of Science and Technology from January 2002 to December 2021 were collected. There were 606 males and 557 females, aged 59(range,20?94)years. Of the 1 163 patients, 129 cases with gastric GIST combined with other digestive tract cancer were divided into the combined group, and 1 034 cases with only gastric GIST were divided into the non-combined group. Observation indicators: (1) clinicopathological features of patients; (2) surgical situations and postoperative complications; (3) follow-up and survival of patients; (4) analysis of prognosis associated affecting factors. Follow-up was conducted using outpatient examination, telephone and online interview to detect survival of patients up to January 2022. The overall survival time was defined as the time from surgery to the last tine of follow-up or the outcome events, such as death of patient, loss of follow-up, etc. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Com-parison of ordinal data was conducted using the non-parameter Mann-Whitney U test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and Log-Rank test was used to conduct survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) Clinicopathological features of patients. Of the 129 patients in the combined group, there were 81 cases combined with gastric cancer, 39 cases combined with esophageal cancer, 8 cases combined with colon cancer and 1 case combined with rectal cancer. Gender (male, female), cases with age ≤60 years or>60 years, cases without or with clinical symp-toms before surgery, cases with tumor diameter of gastric GIST as<2 cm, 2?5 cm, 5?10 cm,>10 cm, cases with mitotic index as <5/50× high power field, 5?10/50× high power field, >10/50× high power field, cases with cell proliferation index of Ki-67 as ≤5% or >5%, cases classified as extremely low risk, low risk, medium risk and high risk of the modified national institutes of health (NIH) risk classification, cases with or without tumor necrosis of the gastric GIST, cases without or with adjuvant imatinib therapy, cases with the expression of DOG-1 detected by immunohistochemical staining as positive or negative, cases with the expression of CD34 as positive or negative were 92, 37, 30, 99, 9, 120, 114, 10, 3, 2, 126, 1, 2, 122, 2, 112, 8, 5, 4, 129, 0, 121, 8, 118, 3, 117, 12 in the combined group, versus 514, 520, 585, 449, 194, 840, 383, 360,201, 90, 799, 155, 80, 851, 143, 337, 308, 192, 197, 960, 74, 769, 265, 850, 80, 990, 44 in the non-combined group, showing significant differences in the above indicators between the two groups ( χ2=21.46, 51.11, 11.06, Z=?10.27, ?5.34, χ2=15.94, Z=?10.61, χ2=9.86, 24.10, 5.52, 6.37, P<0.05). Of the 1 163 patients, there were 12 cases of the combined group suspected diagnosed as gastric GIST before surgery and 1 case of the combined group dia-gnosed as gastric GIST by gastroscopy and pathological examination before surgery. The rest of 1 150 patients were diagnosed as gastric GIST by intraoperative exploration or postoperative pathological examination. (2) Surgical situations and postoperative complications. Of the 129 patients in the combined group, 72 cases underwent open surgery and 57 cases underwent laparoscopic or thoracoscopic surgery including 3 cases converted to open surgery. Of the 1 034 patients in the non-combined group,207 cases underwent endoscopic surgery, 371 cases underwent open surgery, and 456 cases underwent laparoscopic or thoracoscopic surgery including 8 cases converted to open surgery. Incidence of postoperative complications was 10.078%(13/129) in the combined group, versus 2.321%(24/1 034) in the non-combined group, showing a significant difference between the two groups ( χ2=22.40, P<0.05). (3) Follow-up and survival of patients. Of the 1 163 patients, 1 046 cases were followed up for 44(range, 1?220)months, with the postoperative 5-year overall survival rate as 87.2%. The postoperative 5-year overall survival rate was 51.2% in the combined group, versus 91.4% in the non-combined group, showing a significant difference between the two groups ( χ2=169.07, P<0.05). (4) Analysis of prognosis associated affecting factors. Results of univariate analysis showed that gender, age, tumor diameter of gastric GIST as 2?5 cm, 5?10 cm and >10 cm, combined with other digestive tract cancer, mitotic index as >10/50× high power field and tumor necrosis of the gastric GIST were related factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=2.16, 2.27, 0.46, 0.57, 1.75, 7.58, 2.70, 1.80, 95% confidence intervals as 1.52?3.07, 1.60?3.22, 0.29?0.71, 0.34?0.94, 1.11?2.77, 5.29?10.85, 1.67?4.38, 1.08?2.98, P<0.05). Results of multivariate analysis showed that gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index were independent factors affecting the post-operative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=1.91, 1.82, 2.10, 7.11, 2.75, 95% confidence intervals as 1.33?2.75, 1.27?2.62, 1.14?3.87, 4.58?11.04, 1.50?5.03, P<0.05). Conclusions:The tumor diameter of gastric GIST is short in patients combined with other digestive tract cancer, and the risk grade of modified NIH risk classification is lower. Gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index are independent factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST.

Objective:To evaluate the safety and feasibility of neoadjuvant chemotherapy (NACT) combined with radical surgery for elderly patients with locally advanced gastric cancer (LAGC).Methods:One hundred and fourty eight patients with LAGC after NACT and gastrectomy between 2012 and 2020 were retrospectively reviewed. They were divided into two groups: (1) <65 years old (111 cases) and (2) ≥65 years old (37 cases) and their clinicopathological and prognostic data were compared.Results:There was no significant difference between the two groups in the incidence of hematological complications such as anemia ( χ2=0.235, P=0.628), leukopenia ( χ2=0.613, P=0.434), neutropenia ( χ2=0.011, P=0.918) and thrombocytopenia ( χ2=0.253, P=0.615) and non-hematological complications such as nausea ( χ2=0.092, P=0.762), vomiting ( χ2=0.166, P=0.683), diarrhea ( χ2=0.015, P=0.902) and mucositis ( χ2=0.199, P=0.766) due to NACT. There were no statistical differences between the older patients and the younger in operation duration ( t=0.270, P=0.604), intraoperative bleeding ( t=1.140, P=0.250) and R 0 resection rate ( χ2=0.105, P=0.750). The incidence of postoperative complications was 25.2% and 37.8% in the younger patients and the olders ( χ2=2.172, P=0.141). Pleural effusion ( χ2=7.007, P=0.008) and pulmonary infection ( χ2=10.204, P=0.001) was significantly higher in the older patients than in the youngers. The 3-year progression-free survival rate ( t=0.494, P=0.482) and 3-year overall survival rate ( t=0.013, P=0.908) were comparable between the two groups. Conclusions:NACT combined with radical surgery is safe and effective in elderly patients with LAGC, except for higher perioperative pulmonary-related complications.
