Objective:To evaluate the clinical efficacy of TCM Qingjie Huagong Decoction combined with routine internal medicine in the treatment of severe acute pancreatitis with cholelithiasis (bile duct stones) in the early stage.Methods:Thirty-two patients with severe acute pancreatitis combined with cholelithiasis in the first affiliated Hospital of GuangXi University of Traditional Chinese Medicine were selected and randomly divided into two groups with 16 in each, both groups were treated for 14 days. Serum amylase (AMS) was detected by iodine-starch colorimetry, GOT and GPT were detected by continuous monitoring method, and CRP, IL-6 and procalcitonin (PCT) were detected by immune transmission turbidimetry. Acute Physiological and Chronic Health Score Ⅱ (APACHE Ⅱ), CT Severity Index Score (CTSI) and Modified Marshall Score were used to evaluate the severity of SAP. The recovery time of body temperature, the relief time of abdominal distension pain, the recovery time of bowel sounds and the total hospital stay were observed and recorded to evaluate the clinical effect.Results:The total effective rate was 93.8% (15/16) in the treatment group and 75.0% (12/16) in the control group. There was significant difference between the two groups ( χ2=8.19, P=0.042). After treatment, the level of AMS, WBC, CRP, PCT, AST, ALT and IL-6 in the treatment group were lower than those in the control group ( t values were 14.3, 7.24, 9.63, 5.48, 7.05, 7.33, 28.34, respectively, all Ps<0.05); After treatment, the time for body temperature to return to normal [(2.91±0.12)d vs. (3.78±0.38)d, t=8.76], the time for relief of abdominal distension pain [(4.77±0.68)d vs. (7.13±1.55)d, t=9.52], the time for recovery of bowel sounds [(3.90±1.80)d vs. (4.89±1.38)d, t=2.98] and the total hospital stay [(22.60±2.80)d vs. (30.37±3.89)d, t=7.88] in the treatment group were all significantly shorter than those in the control group ( P<0.01); APACHE Ⅱ, CTSI and the Modified Marshall Score in the treatment group were lower than those in the control group ( t values were 11.82, 12.72, 7.71, respectively, all Ps<0.01). Conclusion:Qingjie Huagong Decoction combined with ERCP and conventional western medicine therapy can reduce the level of inflammation in patients with cholelithiasis in the early stage of SAP, relieve clinical symptoms and improve clinical efficacy.

Objective:To analyze the potential mechanism of Qifang Weitong granules in the treatment of gastric cancer based on network pharmacology and molecular docking method.Methods:TCMSP, TCMID, and Swiss Target Prediction databases were used to screen out the chemical components and related targets of Qifang Weitong Granules. GeneCards and OMIM databases were used to screen out the gastric cancer targets to obtain common targets of this disease and Qifang Weitong Granules and upload them to STRING database to form a PPI network, and obtain the key targets and analyze the correlation between the key targets and gastric cancer in Oncomine tumor database. In addition, the regulatory network of gastric cancer and Qifang Weitong Granules was constructed by using Cytoscape software, and the CluoGO plug-in and R language of Cytoscape software were used to perform GO and KEGG enrichment analysis on the key targets. The possibility of the binding between the molecules of this medicine and targeted molecules is verified by molecular docking.Results:There were 168 medicinal chemical components obtained in Qifang Weitong Granules, 2 803 gastric cancer targets, and 49 common targets. In the regulatory network of gastric cancer and Qifang Weitong Granules, β-sitosterol, formononet, stigmasterol have higher values of chemical composition. The key targets in the PPI network are MAPK8, FOS, AR, etc. The GO enrichment analysis focused on the positive regulation of mitochondrial outer membrane permeability in the apoptosis signaling pathway, while the KEGG enrichment analysis is significantly enriched in apoptosis access. The result of molecular docking showed good binding and stable conformation.Conclusion:Qifang Weitong Granules can induce the expression of genes and proteins related to gastric cancer, show its effect by affecting the level of hormones, cell apoptosis and other biological processes, and activating the apoptosis signal pathway.

Objective:To investigate the effects of ectodysplasin-A1 (EDA1) on the proliferation and cell cycle of ameloblast-like epithelial cells (LS8 cells).Methods:Wild EDA1 plasmid pCR3-Flag-EDA1-W (wild group), syndrome mutant EDA1 plasmid pCR3-Flag-EDA1-H252L (mutant group) and empty vector plasmid pCR3-Flag (control group) were transfected into LS8 cells. Cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay and cell cycle was detected by flow cytometry. All tests were repeated three times.Results:Compared with the control group (0.105±0.032), the proliferation activity of the wild group (0.201±0.009) was significantly higher after 72 h ( P<0.05). Compared with the control group (0.168±0.054) and the mutant group (0.194±0.059), the proliferation activity of the wild group (0.386±0.066) was significantly higher after 96 h ( P<0.05). There was no significant difference between the mutant group and the control group at all time points ( P>0.05). In the G 0/G 1 phase, compared with the control group (65.4%±2.1%) and the mutant group (66.6%±3.1%), the cell distribution ratio of the wild group (51.2%±1.1%) was significantly lower ( P<0.01). In the S phase, compared with the control group (23.1%±2.0%) and the mutant group (21.9%±1.8%), the cell distribution ratio of the wild type group (37.3%±2.4%) was significantly higher ( P<0.01). There was no significant difference in cell cycle distribution between the mutant group and the control group ( P<0.05). Conclusions:Wild EDA1 promotes the proliferation of LS8 cells and the transformation from G 0/G 1 to S phase. The syndrome mutant EDA1 (EDA1-H252L) loses its function of regulating the cell proliferation and cell cycle of LS8 cells.

Objective:To explore the clinical effects of fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn.Methods:From April 2018 to April 2019, 12 patients with hypertrophic scar after burn who met the inclusion criteria were admitted to the Department of Plastic Surgery and Burns of Xuzhou Renci Hospital, and were included in this prospective randomized controlled clinical study. There were 7 males and 5 females with age of (32±11) years and scar area of (612±195) cm 2. One scar was selected from each patient and divided into two equal area scars, and they were divided into combined treatment group and laser alone group with 12 scars in each group according to the random number table. The scar in laser alone group was only treated with fractional carbon dioxide laser, while the scar in combined treatment group was injected with autologous granular fat and then treated with fractional carbon dioxide laser. Scars in the two groups were treated once every 2 months, totally 3 times. Before the first treatment and 6 months after the last treatment, the scars in the two groups were evaluated by modified Vancouver Scar Scale (mVSS), hematoxylin-eosin staining and color Doppler ultrasound. Six months after the last treatment, the curative effect of scars in the two groups was evaluated, and the effective number of scar treatment was calculated. The adverse reactions during the whole treatment were recorded. Data were statistically analyzed with independent sample t test, paired sample t test, and McNemar exact probability method test. Results:Six months after the last treatment, the mVSS score of scars in combined treatment group was (4.5±0.4) points, which was significantly lower than (7.8±0.6) points in laser alone group ( t=10.000, P<0.01). Six months after the last treatment, the mVSS scores of scars in combined treatment group and laser alone group were significantly lower than those before the first treatment ((13.5±0.7) and (13.8±0.6) points, t=8.805, 9.010, P<0.01). The effective number of scar treatment in combined treatment group was significantly more than that in laser alone group ( P<0.05). There was no scar aggravation, infection, or other adverse reactions during the treatment of scars in both groups. Before the first treatment, the scars in both groups had large collagen, disordered arrangement, proliferation of capillaries, infiltration of some inflammatory cells, and disappearance of skin appendages. Six months after the last treatment, the scar collagen in both groups was sparse and orderly arranged, and the vascular density was reduced. The improvement of scars in combined treatment group was more obvious than that of laser alone group. Six months after the last treatment, the scar thickness in combined treatment group was significantly smaller than that in laser alone group ( t=2.657, P<0.05). Before the first treatment, the blood flow of scars in both groups was abundant; 6 months after the last treatment, the blood flow of scars in combined treatment group was significantly less than that in laser alone group. Conclusions:Fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn can significantly reduce the pain and itching symptoms of scar, and improve the thickness, texture, and congestion of scar. The combined treatment has synergistic effect and less adverse reactions, providing a more effective treatment for patients with hypertrophic scar.

Objective To explore the application value of the extra-glissonian pedicle transection approach guided by arantius' ligament in laparoscopic left hemihepatectomy.Methods The retrospective cohort study was conducted.The clinical data of 57 patients who underwent laparoscopic left hemihepatectomy in the First Affiliated Hospital of Fujian Medical University from January 2015 to January 2018 were collected.There were 18 males and 39 females,aged from 29 to 75 years,with an average age of 57 years.Of the 57 patients,22 undergoing the laparoscopic left hemihepatectomy with extra-glissonian pedicle transection approach guided by arantius' ligament and 35 undergoing laparoscopic left hemihepatectomy with regular intra-glissonian pedicle transection approach were allocated into the extra-glissonian transection group and intra-glissonian transection group,respectively.Observation indicators:(1) intraoperative situations and postoperative short-term outcomes;(2) postoperative complications;(3) follow-up.Patients were followed up by outpatient examination and telephone interview to investigate postoperative recurrence of diseases up to June 2018.Measurement data with normal distribution were represented as Mean±SD and comparison between groups was analyzed using the t test.Count data were described as absolute number or percentage and comparison between groups was analyzed using the chi-square test.Results (1) Intraoperative situations and postoperative short-term outcomes:the operation time,dissection time of left hepatic pedicle,volume of intraoperative blood loss were (123± 37) minutes,(14± 5) minutes,(337± 169) mL in the extra-glissonian transection group and (148± 27) minutes,(22± 3) minutes,(495±203) mL in the intra-glissonian transection group,respectively,showing statistically significant differences between the two groups (t =2.992,7.733,3.045,P＜0.05).Cases with intraoperative blood transfusion,time of gastrointestinal recovery,time for postoperative drainage-tube removal,duration of postoperative hospital stay were 1,(1.8±0.9)days,(3.2±0.9)days,(8.2± 1.7)days in the extra-glissonian transection group and 4,(2.0± 0.8)days,(3.6±0.8)days,(10.0±4.0)days in the intra-glissonian transection group,respectively,showing no statistically significant difference between the two groups (x2 =0.171,t=1.304,1.857,1.622,P＞0.05).There was no uncontrolled hemorrhage or air embolism in the two groups.(2) Postoperative complications:3 patients had complications of Clavien-Dindo classification Ⅰ in the extra-glissonian transection group including 1 of pulmonary infection,1 of abdominal infection,1 of incisional infection and 7 had complications in the intraglissonian transection group including 2 of pulmonary infection,2 of liver sectional effusion,1 of subphrenic abscess,1 of biliary leakage,1 of incisional infection,showing no statistically significant difference between the two groups (x2=0.066,P＞0.05).Patients with postoperative complications were cured and discharged after symptomatic treatment.There was no perioperative death in the two groups.(3) Follow-up:57 patients were followed up for 5-41 months,with a median time of 23 months.Two and 1 patients had tumor recurrence and hepatolithiasis recurrence in the intra-glissonian transection group,without recurrence of hepatic hemangioma or cholangiocarcinoma.Five patients had tumor recurrence in the intra-glissonian transection group,without recurrence of hepatic hemangioma,hepatolithiasis or cholangiocarcinoma.The disease recurrence rate was 13.6％ (3/22) and 14.3％(5/35) in the extra-glissonian transection group and intra-glissonian transection group,respectively,showing no statistically significant difference between the two groups (x2 =0.104,P＞0.05).Conclusions Extraglissonian pedicle transection approach guided by arantius' ligament in laparoscopic left hemihepatectomy is feasible and effective,which can control hepatic blood inflow of left liver,simplify the surgery procedure and shorten dissection time of left pedicle,in order to save operation time and reduce volume of intraoperative blood loss.

Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Objective To investigate the effect of lower thoracic epidural block on intestinal epithelial cell apoptosis during hemorrhagic shock and resuscitation in rats.Methods Sixty-four male SD rats placed with lower thoracic epidural catheter were randomly divided into four groups (n=1 6 each):group Sham (sham operation),group HSR (hemorrhagic shock and resuscitation),group NS (hemorrhagic shock and resuscitation+epidural saline 100 μl/kg),and group TEA (hemorrhagic shock and resuscitation+epidural 0.075% ropivacaine 100 μl/kg).The hemorrhagic shock was made described by Chaudry.Rats were resuscitated by transfusing shed blood and normal saline 60 min after hemorrhagic shock.Malondialdehyde (MDA)content,superoxide dismutase (SOD)activity, and protein expression of Bax and Bcl-2 in intestinal epithelium were detected,and epithelial apoptosis index was calculated at 2 h after resuscitation.Results Compared with group Sham,intestinal epithe-lial MDA,Bax expression and epithelial apoptosis were significantly increased,while SOD activity were markedly decreased in groups HSR,NS and TEA (P<0.05).Compared with groups HSR and NS,intestinal epithelial MDA,Bax expression and epithelial apoptosis were significantly decreased, while SOD activity and Bcl-2 expression were markedly increased in group TEA (P <0.05 ). Conclusion Lower thoracic epidural block can enhance the antioxidant and anti-apoptotic ability,and inhibit the oxidative stress and cell apoptosis of intestinal epithelium.Therefore,it can promote the survival rate after hemorrhagic shock and resuscitation through protecting intestinal barrier.
