Objective: To provide the mechanism-based pharmacotherapy of the Huatan Qushi formula (HTQS formula), for the health management and treatment of non-alcoholic fatty liver disease (NAFLD). Methods: A rat model of NAFLD was employed to examine the efficacy and safety of the HTQS formula. In vivo active components and potential mechanisms of the HTQS formula were identified using UPLC‒MS/MS combined with network pharmacology. The influence of the HTQS formula on the dominating proteins in PI3K/Akt pathway was validated in vivo using western blot. Finally, 16S rRNA sequencing of the gut microbiome was conducted followed by targeted metabolomics detecting fecal short-chain fatty acids (SCFAs) and bile acids to determine the impact of the HTQS formula on gut microbiota. Results: The HTQS formula reduced weight gain and hepatic steatosis in NAFLD rats and decreased serum total cholesterol (TC), triglycerides, blood glucose, and insulin resistance (IR) without causing liver or kidney injury. We detected 28 components using UPLC‒MS/MS and identified 439 shared targets between NAFLD and the HTQS formula. Primarily, we focused on the PI3K/Akt signaling pathway based on protein‒protein interaction network analysis. We validated that the HTQS formula inhibited liver steatosis and inflammation by increasing the phosphorylation levels of PI3K, AKT, P27, GSK3β in the PI3K/Akt signaling pathway. 16S rRNA sequencing revealed that the HTQS formula reduced the abundance of the genus Family_XIII_AD3011_group, which was positively correlated with IR and taurodeoxycholic acid. In addition, Lachnospiraceae_UCG_010 inversely correlated with TC and five bile acids, which could be essential to the therapeutic effect of the HTQS formula against NAFLD. Conclusions The HTQS formula proved to be an effective pharmacotherapy for NAFLD without causing liver or kidney injury. Multiple potent components of the HTQS formula could alleviate liver steatosis and lipid metabolism disorder by modulating the PI3K/Akt signaling pathway and restoring gut microbiota composition.

Objective:To analyze the efficacy and safety of cranial approach priority, counterclockwise sequential comple mesocolic excision in laparoscopic right hemicolectomy.Methods:From Jan. 2020 to Dec. 2020, 30 patients with right colon cancer in Department of Gastrointestinal Surgery were retrospectively analyzed. Laparoscopic radical right hemicolectomy was performed via the approach of complete mesocolic excision. The general clinicopathological data of the patients, perioperative data such as operation time, intraoperative blood loss, number of cases of hemorrhage caused by Henle trunk and subordinate branch injury, whether or not converted to open surgery, postoperative pathological data (TNM staging, total number of dissected lymph nodes and the number of metastatic lymph nodes) , postoperative recovery (exhaust time, the time of fluid intake, drainage tube removal and hospital stay) , and complications (such as bleeding, anastomotic leakage, secondary surgery, lymphatic leakage, pulmonary infection, abdominal infection, incision infection, etc) were recorded. Follow-up was performed by telephone or outpatient in 1 year after surgery.Results:The total operation time was (197.80±31.20) minutes, ranging from 150 to 275 minutes, and the intraoperative blood loss was (58.33±30.30) ml, ranging from 10 to 100 ml. There were no cases of intraoperative Henle stem and branch injury bleeding or conversion to open surgery. Postoperative exhaust time was (2.97±0.67) d, ranging from 2 to 4d; postoperative fluid intake time was (3.67±0.76) d, ranging from 3 to 5d; postoperative drainage tube removal time was (6.60±4.00) d, ranging from 4 to 25 days; postoperative hospital stay was (7.87±3.94) days, ranging from 5 to 26 days. pTNM staging: 9 cases of stage I, 5 cases of stage IIA, 1 case of stage IIB, 6 cases of stage IIIA, 4 cases of stage IIIB, and 5 cases of stage IIIC. The total number of lymph nodes dissected was (29.50±8.18) , ranging from 19 to 51; the number of metastatic lymph nodes was (1.40±1.77) , ranging from 0 to 6. Postoperative complications included incision infection in 1 case, anastomotic leakage in 1 case, lymphatic leakage in 2 cases, and lung infection in 1 case. No tumor recurrence or metastasis was found during follow-up, and no patient died.Conclusion:Cranial approach priority, counterclockwise sequential complete mesocolic excision is safe and effective in laparoscopic right hemicolectomy.

Objective:To study the effect of enhanced recovery after surgery (ERAS) on intestinal function and gut microbiota changes in patients who underwent laparoscopic gastrectomy.Methods:From Aug. 2018 to Dec. 2019, 80 patients who underwent laparoscopic radical D2 gastrectomy for gastric cancer in the first Department of Gastrointestinal Surgery of Yantai Yuhuangding Hospital were selected. According to whether it adopts ERAS treatment or not, patients were divided into 2 groups (n=40) : ERAS group and traditional perioperative treatment group. The time of postoperative bowel sounds, the time of first exhaust and defecation, the proportion of antibiotic-related diarrhea and surgical site infection (SSI) were recorded. Stools were collected before operation, first time after operation, 1, 2 weeks and 1 month after operation. 16S rRNA sequencing method was used to identify the diversity and species of gut microbiota. The diversity index of intestinal flora in the perioperative period and changes in the proportion of probiotics (bifidobacterium and lactobacillus) were compared.Results:The appearance time of bowel sounds, the first exhaust and defecation time [ (16.25±6.41) h, (23.95±6.02) h, (34.95±9.34) h] in ERAS group were significantly earlier than those in the traditional treatment group [ (22.3±6.49) h, (28.45±7.12) h, (48.1±15.64) h], and the difference was statistically significant ( P<0.05) . The incidence of antibiotic-related diarrhea was higher in the traditional treatment group (3/40) than in ERAS group (1/40) , but the difference was not statistically significant ( P>0.05) . The ratio of postoperative SSI was slightly higher in ERAS group, but the difference was not statistically significant ( P>0.05) . In the perioperative period, the intestinal flora diversity index (Chao1 and Shannon index) and the proportion of probiotics (lactobacillus acidophilus and bifidobacterium) were not significantly different between the two groups before surgery ( P>0.05) ; while at the first time, one week, 2 weeks after the operation, and 1 month after the operation, ERAS group was higher than the traditional group ( P<0.05) ; and at each postoperative time point, the traditional group decreased significantly than the ERAS group. The first time decrease was the largest, ( P<0.05) ; With the passage of time after operation, the diversity of intestinal flora and the proportion of probiotics gradually recovered. By 1 month after operation, the two groups did not return to the preoperative gut microbiota diversity state or proportion. Conclusion:The concept of enhanced recovery after surgery (ERAS) promotes the recovery of intestinal function in patients with gastric cancer, does not reduce the proportion of antibiotic-associated diarrhea (AAD) or surgical site infections (SSI) , and maintains the diversity of gut microbiota balance and stability.

Objective:To evaluate the ultrasonography-guided percutaneous leverage reduction in the treatment of pediatric radial neck fractures.Methods:From May 2016 to May 2018, 42 patients with Judet Ⅲ or Ⅳ radial neck fracture were treated at Department of Pediatric Orthopedics, The Second Hospital of Fuzhou. They were 15 boys and 27 girls, aged from 3 to 12 years. All of them were treated by percutaneous leverage reduction and Métaizeau technique. The operative procedures were guided by ultrasonography in 20 cases and by C-arm fluoroscopy in 22 cases. Postoperative evaluation was based on Métaizeau imaging criteria, Tibone and Stoltz functional criteria; complications such as radial nerve injury were recorded.Results:There were no statistically significant differences between the ultrasonography-guided group and the fluoroscopy-guided group in preoperative general data, showing comparability ( P>0.05). There were no significant differences between the 2 groups in terms of Métaizeau imaging, Tibone or Stoltz functional scores ( P>0.05). The frequency of fluoroscopy was (2.7±0.6) times for the ultrasonography group and (14.6±3.4) times for the fluoroscopy group while the operation time averaged (25.8±5.9) min for the former and (38.1±9.2) min for the latter, showing significant differences ( P<0.05). No postoperative complications were observed in the ultrasonography group while 4 cases of radial nerve injury in the fluoroscopy group, also showing significant difference between the 2 groups ( P< 0.05). Conclusion:Ultrasonography-guided percutaneous leverage reduction is a suitable surgical treatment of radial neck fracture in children, because it is simple, effective and safe.

How to effectively repair esophageal fistulas, caused by esophageal perforation, rupture and anastomotic leakage after esophagectomy has always been a key problem for the digestive surgeon. Although there are many clinical treatment methods, the therapeutic effect is still completely unsatisfactory, especially when severe mediastinal purulent cavity infection is associated with the esophageal fistula. In recent years, foreign centers have promoted a new minimally invasive endoscopic treatment technology to repair the esophageal fistula, endoscopic vacuum-assisted closure therapy, with significantly curative effect. In this article, we will review the specific operation, advantages and disadvantages, as well as the clinical efficacy of endoscopic vacuum-assisted closure therapy in treating the esophageal fistulas, to provide a new therapeutic technique for esophageal fistulas and expand the new field of minimally invasive endoscopic therapy.

Objective To explore the clinical effect of inner heating dry needle therapy on nonspecific chronic neck pain (NCNP). Methods From October, 2017 to March, 2018, 60 patients with NCNP were randomly divided into needle group (n=30) and magner group (n=30). The needle group received inner heating dry needle therapy, and the magner group received hot magner therapy. They were measured the strain ratio (SR) of bilateral trapezius muscles, scalp clamp muscles, cephalospinal muscles, semispinalis muscles and multifidus muscles with ultrasound elastography before, and one week and one month after treatment, respectively, while they were assessed with Visual Analogue Scale (VAS) of pain and Neck Disability Index (NDI). Results The scores of VAS and NDI decreased in both groups one week and one month after treatment (t>2.693, P<0.05), and decreased more in the needle group than in the magner group (F>8.048, P<0.001). SR of all the muscles decreased in the needle group one week and one month after treatment (F>6.22, P<0.01), and only decreased in the right cephalospinal muscles in the magner group (F=4.35, P<0.05).Conclusion Inner heating dry needle therapy could recover the neck muscle elasticity to relieve pain and improve ceivical function in patients with NCNP.

Objective To observe the effects of percutaneous endoscopic gastrostomy (PEG)on mortality and complications in patients with persistent dysphagia after stroke using a points scoring system for selecting PEG indication.Methods A total of 75 patients were divided into low score group without PEG,high score group without PEG and low score group with PEG (n=25 each).The follow-up period was 18 months,and the differences in complications,mortalities and survival periods among groups were compared.Results The number of times of aspiration pneumonia was (1.36± 1.44) in low score group,(1.96±2.28) in high score group,(0.36±0.64) in low score group with PEG,with statistically significant differences among three groups (H=7.148,P=0.028).No difference in the morbidity of aspiration pneumonia was found between low score group and high score group (P=0.189).The number of times of aspiration pneumonia was decreased in low score groups after PEG versus in low score group without PEG (P=0.030) and in high score group (P＜0.01).The numberof times of gastrointestinal hemorrhage was (0.48± 0.77)in low score group,(0.64± 0.91) in high score group,(0.12±0.33) in low score group with PEG,with statistically significant differences among three groups (H=5.532,P =0.063).No statistically significant difference in gastrointestinal hemorrhage was found between low score groups and low score group after PEG (P=0.430),as well as between low score group and low score group with PEG (P=0.079).The morbidity of gastrointestinal hemorrhage was lower in low score group than in high score group (P=0.012).The survival rate at the observation end was 88.0％ (22/25),52.0％ (13/25) and 92.0％ (23/25) in low score group,high score group and low score group with PEG,respectively,with statistically significant difference among the three groups (x2 =7.906,P =0.001).Kaplan-Meier survival curve showed that the survival period were longer in the low score group with or without PEG than in high score group (P＜0.01),but no statistically significant difference was found between low score groups with or without PEG (P=0.626).Conclusions The reasonable evaluation using a points-scoring system before PEG might predict the prognosis of such patients:the higher score would indicate higher mortality.PEG operation for low score group with better condition could decrease the aspiration pneumonia and decrease gastrointestinal hemorrhage significantly,but could not prolong general survival time and decrease general mortality.

Objective To evaluate the long-term efficacy of antiretroviral therapy and drug resistance among human immunodeficiency virus-1(HIV-1)-infected children in Yunnan.Methods In this retrospective study,CD4+T cell counts,HIV viral loads and genetic drug resistance results were obtained from HIV-1-infected children who were treated with antiretroviral treatment between January 2004 to July 2015.Results A total of 1 078 HIV/acquired immune deficiency syndrome(AIDS)children were treated with antiviral therapy.Before treatment,the average CD4+cell number was(466.8 ± 397.2)cells/μL. The percentages of children with CD4+cell count >750 cells/μL after 1-year,3-year,5-year and 8-year treatment were 54.31%,62.87%,68.46% and 74.19%,respectively.Virological failure occurred in 150 HIV/AIDS children(13.9%),and the virological failure rate was 4.3/100 child-years.Among those 150 patients with virological failure,104 cases(69.33%)exhibited genetic resistance to antiretroviral drugs.The prevalent mutations associated with drug resistance were M 184V/I(75.0% [78/104]), K103N(43.3%[45/104]),G190A(29.8%[31/104]),Y181C(22.1%[23/104]),T215Y/F(20.2%[21/104]).Conclusions After long-term antiretroviral treatment,most of the HIV-infected children have restored the immunity and suppressed HIV viral replication successfully.HIV resistance is the main cause of virological failure.Drug resistance mutations mainly occur in nucleoside reverse transcriptase inhibitor and non-nucleoside reverse transcriptase inhibitor,and the resistance rate of proteinase inhibitor is low.Early genetic resistance testing and switch to second-line therapy will improve the treatment outcome.

Objective To study the expression of ALK protein in pulmonary adenocarcinoma as detected by Ventana immunohistochemistry, with correlation of clinicopathologic features. Methods Immunohistochemical study for ALK protein using Ventana ALK ( D5F3) kit was carried in 7 371 pulmonary adenocarcinoma samples.The clinicopathologic features were subsequently analyzed.Results ALK fusion protein was detected in 446 of the 7 371 lung adenocarcinoma samples studied ( 6.05%) .The ALK positivity rate in small biopsy samples was higher than that in surgical specimens [ 9.02% ( 153/1 696 ) versus 5.16%(293/5 675);P<0.01] .ALK fusion protein expression correlated with patient age, sample type and smoking history.ALK positivity rate in each age group increased with younger patient age.ALK positivity rate was 45.45%(10/22) in patients younger than 30 years old.The positivity rate of ALK fusion protein in adenocarcinoma in-situ, minimally invasive adenocarcinoma and invasive adenocarcinoma was 0, 0.48%(2/418) and 5.63% (291/5 165), respectively.The differences of ALK positivity rate amongst different subtypes had statistical significance ( P<0.01 ).Invasive mucinous adenocarcinoma had highest ALK positivity rate, followed by invasive adenocarcinoma with predominantly solid pattern.Conclusions ALK fusion protein is more often found in young patients with pulmonary adenocarcinoma, especially in those younger than 30 years old.ALK fusion protein is rarely expressed in early-stage pulmonary adenocarcinoma. Invasive mucinous adenocarcinoma and invasive adenocarcinoma with solid pattern have higher ALK positivity rate than other adenocarcinoma subtypes.
