ObjectiveTo investigate the therapeutic effect of Qingjie Huagong decoction （QJHGD） on a mouse model of severe acute pancreatitis （SAP） and the mechanism of action of QJHGD against inflammatory response. MethodsA total of 36 male C57BL/6J mice were randomly divided into blank group， model group， Western medicine group （ulinastatin）， and low-， middle-， and high-dose QJHGD groups， with 6 mice in each group. All mice except those in the blank group were given 5% sodium taurocholate by retrograde pancreaticobiliary injection to establish a model of SAP. After modeling， the mice in the low-， middle-， and high-dose groups were given QJHGD （1， 2， and 4 g/kg， respectively） by gavage， and those in the Western medicine group were given intraperitoneal injection of ulinastatin （5×10⁴ U/kg）， for 7 days in total. HE staining was used to observe the histopathological changes of the pancreas； ELISA was used to measure the levels of α-amylase， lipase， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， interleukin-18 （IL-18）， and tumor necrosis factor-α （TNF-α） in mice； RT-qPCR was used to measure the mRNA expression levels of NOD-like receptor protein3 （NLRP3）， Toll-like receptor 4 （TLR4）， and nuclear factor-kappa B （NF-κB） in pancreatic tissue； immunohistochemistry was used to measure the positive expression rates of NLRP3， TLR4， and NF-κB in pancreatic tissue； Western blot was used to measure the protein expression levels of NLRP3， TLR4， NF-κB， IL-1β， and IL-6. An analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the blank group， the model group had diffuse destruction of pancreatic tissue structure， focal dilatation of pancreatic lobular septum， pancreatic acinar atrophy， and massive inflammatory cell infiltration， as well as significant increases in the content of α-amylase， lipase， IL-1β， IL-6， IL-8， IL-18， and TNF-α （all P<0.05）， the mRNA expression levels and positive expression rates of NLRP3， TLR4， and NF-κB （all P<0.05）， and the protein expression levels of NLRP3， TLR4， NF-κB， IL-1β， and IL-6 （all P<0.05）. Compared with the model group， the low-， middle-， and high-dose QJHGD groups and the Western medicine group had slightly tighter and more intact structure of pancreatic tissue， ordered arrangement of pancreatic acinar cells， a small amount of inflammatory cell infiltration， and hemorrhagic foci of pancreatic lobules， as well as significant reductions in the content of α-amylase， lipase， IL-1β， IL-6， IL-8， IL-18， and TNF-α （all P<0.05）， the mRNA expression levels and positive expression rates of NLRP3， TLR4， and NF-κB （all P<0.05）， and the protein expression levels of NLRP3， TLR4， NF-κB， IL-1β， and IL-6 （all P<0.05）. ConclusionQJHGD may exert a protective effect on the pancreatic tissue of SAP mice by inhibiting the activation of NLRP3/TLR4/NF-κB signaling pathway-related proteins， reducing the release of inflammatory mediators， and preventing the enhancement of inflammatory cascade response.

OBJECTIVE To explore the the reg ulation of intestinal flora and effects of Qingjie huagong decoction on intestinal mucosal barrier in severe acute pancreatitis （SAP）mode rats . METHODS SAP rat model was induced by intraperitoneal injection of caerulein and lipopolysaccharide.The survival state of rats in each group were observed.The levels of serum amylase ，interleukin 10（IL-10），IL-18 and IL- 1β in serum were all detected. The pathological changes of pancreatic and small intestinal tissue were observed. The expressions of Occludin，ZO-1 and HMGB1 were detected in small intestinal tissue of rats. The structure and relative abundance of intestinal microflora in rats were detected by 16S rRNA high throughput sequencing. RESULTS After the intervention of Qingjie huagong decoction ，abdominal distension symptoms of SAP model rats were significantly relieved ，and their mental state recovered better ；the levels of serum amylase and IL- 18 in serum were decreased significantly （P＜0.05），while the level of IL- 10 was increased significantly （P＜0.05）. The necrotic area of pancreatic tissue and the infiltration of inflammatory cells were reduced ， the degree of intestinal epithelial cell structural disorder was alleviated ，and the shedding of intestinal mucosal epithelium was reduced.The protein expression of HMGB 1 in small intestinal tissue was decreased significantly （P＜0.05），and the protein expression of Occludin and ZO- 1 were increased significantly . Results of 16S rRNA high throughput sequencing showed that Qingjie huagong decoction could increased the relative abundance of probiotics such as Bacteroidea and Lactobacillus in rat intestine ，reduced the colonization of harmful bacteria such as Firmicutes. CONCLUSIONS Qingjie huagong decoction can improve the intestinal barrier by up-regulating the expression of Occludin and ZO- 1 in small intestinal tissue and down-regulating the protein expression of HMGB 1. It can also adjust the relative abundances of different flora to protect the intestinal tract.

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.

Fifteen patients with sinus-type pressure ulcer in ischial tuberosity were admitted to our unit from April 2013 to April 2017, including 12 patients of unilateral pressure ulcer and 3 patients of bilateral pressure ulcer. The wounds were with infection of different degrees. The outer wound area of pressure ulcer before debridement ranged from 1.5 cm×1.0 cm to 6.0 cm×5.0 cm. Fifteen patients with 15 pressure ulcers were treated with vacuum sealing drainage for 3 to 13 days after debridement and sinus wall resection. Unilateral pressure ulcer was repaired with posterior femoral bilobed flap. One side of bilateral pressure ulcer was repaired with posterior femoral bilobed flap, and the other side was repaired with gluteus maximus muscle flap combined with local flap. The size of flaps ranged from 11.0 cm×7.5 cm to 15.0 cm×10.0 cm. Epidermis of the distal part and edge of the main flap was removed to make complex dermal tissue flap to fill the deep cavity. The other part of the main flap was applied to cover wound, and another flap of the bilobed flap was applied to cover the donor site where main flap was resected. The donor sites were sutured directly. The posterior femoral bilobed flaps in 15 patients survived after operation. Pressure ulcers of 12 patients were healed well. Incision of 2 patients ruptured and healed 15 days after second sewing. One pressure ulcer with infection under the flap healed on 16 days post second completely debridement. During follow-up of 3 to 18 months, flaps were with soft texture, good appearance, and no recurrence.

Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.
