Objective:To explore the efficacy and safety of Ganhai Weikang capsule (GWC) in the treatment of functional dyspepsia (FD).Methods:A randomized, double-blind, placebo-controlled parallel, multi-center, superiority clinical trial was conducted. From March 2018 to April 2020, totally 324 patients with dyspepsia symptoms, who were diagnosed as chronic non-atrophic gastritis by endoscopy and pathology and met the Rome Ⅳ diagnostic criteria for FD from 7 top hospitals were enrolled, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Heilongjiang Hospital of Traditional Chinese Medicine, Tianjin Academy of Traditional Chinese Medicine Affiliated Hospital, Qilu Hospital of Shandong University, the First Affiliated Hospital of Zhejiang University, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University and the Third Xiangya Hospital of Central South University. The patients were randomly divided into the GWC group and the placebo group according to the ratio of 1∶1. The patients of GWC group were given GWC and the patients of placebo group were given GWC capsule simulant. The patients of both groups orally took capsules before meals, 2.4 g each time and 3 times per day, and the course of treatment was 4 weeks. The main efficacy index was the total clinical effective rate after 4 weeks, and the secondary efficacy index was the changes of clinical symptom scores of upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety. The safety index included laboratory tests and adverse events. Chi-square test and Wilcoxon rank sum test were used for statistical analysis.Results:A total of 320 FD patients were enrolled in the full analysis set (FAS), which included 161 cases in GWC group and 159 cases in placebo group. A total of 298 cases were in the per-protocol set (PPS), 149 cases each in GWC group and placebo group. The results of FAS and PPS both showed that the total clinical effective rates of the GWC group were higher than those of the placebo group (84.5%, 136/161 vs. 44.0%, 70/159 and 83.9%, 125/149 vs. 46.3%, 69/149), and the differences were statistically significant ( χ2=57.07 and 46.32, both P<0.001). In addition, the differences of the total score of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (FAS: 10 (7, 14) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 3); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs. 1 (0, 3). PPS: 10 (7, 13) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 2); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs.1 (0, 3)), and the differences were statistically significant (FAS: Z=5.80, 5.91, 3.19, 3.72 and 3.30; PPS: Z=5.14, 5.11, 2.86, 3.21 and 2.84; all P<0.01). The results of FAS and PPS indicated that the improvement rates of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) of GWC group were all higher than those of the placebo group (FAS: 77.8% (54.6%, 91.3%) vs. 42.9% (28.6%, 61.5%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 60.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 41.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%). PPS: 77.8% (54.2%, 89.5%) vs. 44.0% (28.6%, 65.0%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 46.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%)), and the differences were statistically significant (FAS: Z=8.60, 7.72, 4.98, 4.24 and 5.61; PPS: Z=7.90, 7.03, 4.49, 3.88 and 4.83; all P<0.001). After 2 weeks of treatment, the differences of the total score of main symptoms and score of each symptom (upper abdominal pain, upper abdominal burning and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (5.0 (3.0, 8.0) vs. 4.0 (2.0, 6.0); 2.0 (1.0, 2.0) vs. 2.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0)), and the differences were statistically significant ( Z=2.95, 3.44, 2.43 and 2.79, all P<0.05). There was no significant difference in the incidence of adverse events between the GWC group and the placebo group (0.6%, 1/163 vs. 0, 0/159). Conclusion:The clinical total effective rate of GWC in the treatment of FD is superior to that of placebo and it has good safety.

Objective:To investigate the relationship between the expression of hepatocyte nuclear factor-1 α (HNF-1α) and the occurrence and development of liver inflammation and fibrosis in liver tissues of patients with chronic hepatitis B.Methods:Sixty-four patients with chronic hepatitis B who were diagnosed and treated in our hospital from 2011 to 2018 were selected. All patients underwent ultrasound-guided aspiration liver biopsy. The pathological results of liver biopsy were collected for inflammation grading and fibrosis staging. The liver puncture biopsies was collected by paraffin sectioning. The expression of HNF1α in the liver tissue was detected by immunohistochemical staining. Mantel-Haenszel χ2 test was used for bidirectional ordered grouping data, and Spearman’s rank-correlation test was used for rank correlation analysis. Results:There were varying degrees of inflammatory necrosis and fibrosis in the liver tissues of patients with chronic hepatitis B. There was a linear relationship between the expression of HNF1α and the level of inflammation in liver tissues ( χ2MH = 40.70, P < 0.05). The expression of HNF1α in liver tissues of patients with chronic hepatitis B was decreased with the increase of liver inflammation. The expression intensity of HNF1α was negatively correlated with the inflammation grade ( rs = -0.815, P < 0.05). There was a linear relationship between the expressions of HNF1α and the degree and stage of liver fibrosis ( χ2MH = 31.95, P < 0.05). The expression level of HNF1α in liver tissue was gradually decreased with the aggravation of liver fibrosis. The expression intensity of HNF1α was negatively correlated with fibrosis stage ( rs = -0.713, P < 0.05). Conclusion:HNF1α is closely related to the occurrence and development of liver tissue inflammation and fibrosis, and is expected to be a sensitive indicator for evaluating the level of liver tissue inflammation and fibrosis in patients with chronic hepatitis B. In addition, its down-regulation may be involved in the process of occurrence and development of liver inflammation and liver fibrosis, and may become a new target for the treatment of chronic hepatitis B.

Objective: To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis. Methods: The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results: Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years. There were 30 patients in the observation group and 22 in the control group. (1) Surgical situations: the operation time and volume of intraoperative blood loss were (133±19)minutes and (47±21)mL in the observation group, and (136±22)minutes and (49±23)mL in the control group, respectively, showing no significant difference between the two groups (t=-0.386, -0.211, P>0.05). (2) Postoperative situations: time to out-of-bed activity, time to initial food intake, time to first anal flatus, duration of postoperative hospital stay, and hospital expenses were (18±4)hours, (19±5)hours, (28±2)hours, (4.0±1.0)days, and (1.82±0.22)×10⁴ yuan in the observation group, and (29±7)hours, (46±9)hours, (37±4)hours, (6.6±1.6)days, and (2.25±0.29)×10⁴ yuan in the control group, respectively, showing significant differences between the two groups (t=-7.054, -14.169, -9.426, -6.582, -5.809, P<0.05). (3) Postoperative complications: 1 of 30 patients in the observation group had postoperative biliary leakage, with a postoperative complication rate of 3.3%, and was cured after symptomatic support treatment. Six of 22 patients in the control group had postoperative complication, with a postoperative complication rate of 27.3%, including 2 of biliary leakage, 1 of hemorrhage, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, and they were cured after symptomatic support treatment. There was a significant difference between the two groups (χ²=4.358, P<0.05). (4) Postoperative pain scores: from postoperative 6 hours to 48 hours, the postoperative pain score changed from 2.4±0.7 to 1.9±0.9 in the observation group, and from 4.1±0.7 to 2.9±0.9 in the control group, respectively, showing a significant difference in the changing trend between the two groups (F=78.053, P<0.05). (5) Changes in hepatic function and blood routine during perioperative period: from preoperation to postoperative 3 days, levels of alamine aminotransferase (ALT), aspartate transaminase (AST), gamma-glutamyltransferase (GGT), total bilirubin (TBil), and count of white blood cells in the observation group changed from (77±20)U/L to (53±12)U/L, from (85±22)U/L to (61±17)U/L, from (166±39)U/L to (55±24)U/L, from (40±13)μmol/L to (29±12)μmol/L, from (7.0±2.0)×10⁹/L to (6.8±1.9)×10⁹/L, and changed from (79±23)U/L to (62±14)U/L, from (88±24)U/L to (64±17)U/L, from (179±34)U/L to (74±29)U/L, from (45±13)μmol/L to (35±12)μmol/L, from (7.9±2.4)×10⁹/L to (7.5±1.9)×10⁹/L in the control group, respectively. The levels of ALT, AST, GGT, TBiL, and count of WBC showed increasing at postoperative 1 day, and decreasing at postoperative 3 days. There was no significant difference in the changing trend between the two groups (F=0.058, 0.471, 3.021, 1.593, 2.172, P>0.05). Conclusion ERAS is safe and effective in the laparoscopic surgery for choledocholithiasis comorbid with cholecystolithiasis.

Objective To discuss pathological features of three cases of uterine primary NHL(non Hodgkin′s lymphoma).Methods The clinical and pathological data of 3 cases of NHL were collected.Immunohistochemical method was used to label the tumor cells.Their histological types were classified by the latest WHO Classification of Tumors of Haematopoietic and Lymphoid Tissues,and then differential diagnosis with other uterus diseases was offered.Results Three cases were presented with abnormal vaginal bleeding or ejecting as the first symptom,which was easily misdiagnosed as common diseases of the uterus in preliminary clinical and pathological diagnosis.Histopathology of general uterus specimens demonstrated that case one expressed CD3,CD56,TiA-1 and so on,and detected EBV virus cells expression,which supported the diagnosis of NK/T cell lymphoma.Another two cases expressed B cell-specific markers(CD20) and so on,and these tumor cells volume was 3 times larger than that of lymphocyte.These tumor cells had high proliferation index and supported diffuse large B-cell lymphoma diagnosis.Conclusion The tumor cells are like lymphocytes.We infiltrate endometria and myometrium,which is difficult to identify from endometria stromal sarcoma and other tumors,and need to use immunohistochemistry(IHC) for definitive diagnosis and differential diagnosis.

Objective To explore the normal values for two-dimension solid state high resolution anorectal manometry (HRAM) in healthy adult volunteers.Methods The healthy adult volunteers were recruited by advertisement and underwent solid state HRAM in the left lateral position.Anorectal pressures and rectal sensation were recorded and analyzed.Results (1) A total of 126 Chinese healthy adult volunteers (male:50 cases (39.7％);age:(37.5 ± 14.2) years old) were recruited in this study.(2)Mean anal resting pressure (MERP) was (71.8 ± 17.3) mmHg (1 mmHg =0.133 kPa).Maximum anal resting pressure (MARP) was (79.3 ± 17.8) mmHg,Maximum anal squeeze pressure (MSP) was (178.7 ± 52.8) mmHg.Anal high pressure zone (HPZ) length was (3.4 ± 0.6) cm.During simulated evacuation,residual anal pressure (RAP) was (63.8 ±20.5) mmHg,and anal relaxation rate (ARR) was (37.0 ± 11.5) ％.Rectal threshold volume for first sensation (FST),desire to defecate (DDT),urgency to defecate (UDT) and maximum discomfort (MDT) was (47.4 ±10.0) ml,(84.5 ±18.2) ml,(125.8 ± 28.5) ml,and (175.5 ±36.1) ml,respectively.(3) Compared with female subjects,male subjects had higher MSP [(211.0 ± 50.7) mmHg vs (157.5 ± 42.5) mmHg],RAP [(71.6 ± 18.1) mmHg vs (58.8 ± 20.5) mmHg]and rectal MDT[(187.0 ±36.4) mmHg vs (168.0 ±34.1)mmHg],but lower ARR [(32.1 ±8.0)％ vs (40.2 ±12.3)％],all P＜0.01.(4) MERP,MARP,MSP and rectal MDT were higher in young group (≤ 40 years old),all P ＜ 0.05.Conclusions These observations provide normal values for two-dimension solid state HRAM,which have significant difference between genders and different age groups.

Objective:To explore the risk factors,preventive measures and therapeutic methods for bronchopleural fistula (BPF) after lung resections.Methods:A restrospective analysis for 11 patients with BPF after pneumonectomy from April 2012 to June 2016 in Department of Thoracic Surgery,Xiangya Hospital,Central South University was performed.Their clinical characteristics,treatment and prognosis were analyzed,and the risk factors and effective therapeutic strategies were summarized.Results:Among the 11 patients with BPF,10 cases were cured finally,and 1 case with conservative treatment was dead.The total mortality rate was 9.09％.The 10 patients treated with positive measures were all cured,including 5 cases with pulmonary lobectomy and pneumonectomy,4 cases with amplatzer and covered stent,and 1 case with fibrin glue.One case with conservative treatment was dead because of respiratory failure.Conclusion:It is important to intervene BPF as early as possible.Fibrin glue via bronchoscope for tiny BPF after lung resection is preferred to be considered.We recommend to take early positive operation (pulmonary lobectomy and pneumonectomy) after pulmonary resection if the BPF cannot be cured via bronchoscope whereas the patients' condition is allowed.The amplatzer or covered stent should be considered first for the patient with BPF after pneumonectomy.

OBJECTIVETo study the clinical effect and surgical operating points of pararectus approach for the internal fixation of acetabular both-column fractures with concurrent displaced quadrilateral plate fractures.

METHODSFrom January 2012 to December 2013, in the Third Affiliated Hospital of Southern Medical University, 15 patients with acetabular both-column fractures and displaced quadrilateral plate fractures were surgically managed through the pararectus approach. There were 11 male and 4 female patients, with an average age of 40 years (from 19 to 61 years). According to Judet-Letournel classification, there were 9 anterior column plus posterior hemitransverse fractures, 6 both-column fractures, 8 cases involving the pelvic fracture. All these fractures were treated through the pararectus approach, in the horizontal position with general anesthesia. The pre-bended plate was placed in interior pelvic ring to fix the anterior wall, anterior column and quadrilateral plate in direct sight. Then, the posterior column was exposed and fixed with antegrade lag screw. Patients were followed up in 4 weeks, 12 weeks, 6 months, 1 year after the operation, and the anteroposterior radiograph of pelvis and the X-ray examination of the fractured hip was performed.

RESULTSAll the 15 cases underwent the operation successfully. Postoperative X-ray and CT exams showed excellent and good reduction of anterior column, posterior column and quadrilateral plate, with none surgical complication occurred. According to the Matta radiological evaluation postoperatively, reduction of acetabular fracture was rated as excellent in 9 cases, good in 3 cases and poor in 3 cases. The rate of excellent and good was 12/15. After 8 to 18 months' follow-up (median follow-up time was 14 months), all the patients gained bone union. According to the modified Merle D'Aubigne and Postel scoring system, 9 cases were excellent, 4 were good, and 2 were fair. The rate of excellent and good was 13/15.

CONCLUSIONSSurgical management of acetabular fractures through the pararectus approach can provide adequate exposure of reducing and fixing both-column acetabular fractures with concurrent displaced quadrilateral plate fractures, which has a good effect in clinical application.

Objective To evaluate the effectiveness of three neurological assessments in experimental autoim?mune encephalomyelitis. Methods Thirty-two female C57BL/6 mice (18-20g) were randomly divided into normal group (n=15) and immune group (n=17). Immune group were induced subcutaneously in the flank by emulsion consisted of MOG33-35 and complete Freund’s adjuvant. Mice were assessed by two investigators for 35 days after immunization in a blinded manner using Kono’s 5-point criterion, Weaver’s 15-point criterion and improved 15-point criterion. Based on H&E staining, we analyzed the accuracy, sensibility and dependency of three assessments. Results 35-day clini?cal-score plots revealed that the fluctuation of symptoms was more obvious in improved 15-point criterion compared with the other two criteria. 15-point criterion and improved 15-point criterion are more accurate than 5-point criterion in atypical-onset EAE. 15-point criterion and improved 15-point criterion could detect the neurological deficits much earli?er than 5-point criterion (P<0.001). Neurological scores assessed by improved 15-point were well correlated with the pathological findings during the peak and remission stage. Conclusion Improved 15-point criterion is better neurological score system than Kono’s 5-point criterion and Weaver’s 15-point criterion because of its accurate assessment of the neurological deficits in experimental autoimmune encephalomyelitis.
