The present study investigated the mechanism of total flavonoids from Ampelopsis grossedentata(AGTF) against gouty arthritis(GA) by network pharmacology and experimental validation. The main active ingredients and targets of AGTF, as well as disease targets, were screened out using relevant databases and literature data. The "protein-protein interaction"(PPI) network and "drug-ingredient-target-pathway" network were constructed, and the potential targets and mechanism of AGTF against GA were predicted. The hyperuricemia(HUA) combined with GA model was induced in rats. The gait behaviors of rats were scored, and ankle swelling degree was observed. The uric acid(UA) level and xanthine oxidase(XOD) activity in the rat serum were detected, and the levels of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) were measured. The protein expression of toll-like receptor 4(TLR4), myeloid differentiation factor 88(MyD88), and nuclear factor-kappa B(NF-κB) in the synovial tissues of the rat ankle joint was determined by immunohistochemistry. Ten active ingredients of AGTF and 73 candidate targets of AGTF against GA were screened out by network pharmacology. Eighty-six signaling pathways were enriched, including TNF signaling pathway, NF-κB signaling pathway, TLR signaling pathway, Nod-like receptor signaling pathway, and purine metabolism signaling pathway, which were closely related to AGTF against GA. Animal experimental results showed that AGTF could effectively improve the abnormal gait behaviors of GA rats, relieve ankle inflammation, and reduce ankle joint swelling. In addition, AGTF could significantly reduce UA level, inhibit XOD activity, decrease TNF-α, IL-6, and IL-1β content, and down-regulate the expression of TLR4, MyD88, and NF-κB in ankle synovial tissues(P<0.05, P<0.01). The results of network pharmacology and experimental validation are consistent, indicating that AGTF exerts its therapeutic effect on GA by regulating UA metabolism, improving abnormal UA level, reducing the release of inflammatory factors, and regulating immunity and the TLR4/MyD88/NF-κB inflammatory pathway.

Background: As a large, prospective, multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score (COSSH-ACLFs), has been approved by some foreign scholars; however, its predictive value needs to be verified. This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF. Methods: This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014. Spearman method was used to assess the correlation of COSSHACLFs with classical scores. Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF, and stratified analysis was used to further verify the stability of this relationship. We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve (AUROC) and Z-test. Results: A total of 975 patients with HBV-ACLF were screened, and 751 were analyzed (623 male and 128 female). COSSH-ACLFs was the highest in patients with end-stage ACLF, followed by those with middle- and early-stage ACLF (H = 211.8, P < 0.001). In the fully adjusted model, COX multivariate regression analysis revealed that COSSH-ACLFs (as a continuous variable) was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days (hazard ratio [HR]: 1.37 [1.22, 1.53], P < 0.001) and 90 days (HR: 1.43 [1.29, 1.58], P < 0.001). The same trend could be observed in the crude model and minimally adjusted model. The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792, respectively, indicating a stronger predictive accuracy than those of classic models. Conclusions COSSH-ACLFs, with a superior predictive accuracy compared with other classical scores, can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.

Objective:Our study was aimed to analyze the therapeutic effect of early sequential enteral nutrition on postoperative rehabilitation in patients with gastric cancer.Methods:Patients with gastric cancer receiving surgery at our hospital from 2016 to 2017 included and the clinical information was prospective collected and analyzed.Patients were randomly divided into two groups using random number table.Patients in group A were sequentially given amino acid type,short peptide type and then whole protein type,while those in group B received whole protein formulation only.The recovery of gastrointestinal function,postoperative systemic inflammatory response,six-minutes walking test,and enteral nutrition-related complications were compared between the two groups.Results:A total of 71 patients were included in this study (Group A 36 cases,Group B 35 cases).There was no significant difference in terms of the restart anal exhaust between the two groups (P ＞ 0.05).Patients in group A had a significantly shorter postoperative hospitalization (t =4.070;P ＜ 0.01) and the earlier restoration of oral intake than that of Group B (t =3.400;P =0.001).One week after surgery,the levels of CRP (t =2.547;P =0.013) and IL-6 (t =3.172;P =0.002) were significant lower in group A when compared with group B.In addition,patients in group A had a significant higher six minutes walk steps than those in Group B [(416.1 + 36.7) m vs (358.9 ± 32.7) m;t =6.927,P ＜ 0.01].However,no significant difference in enteral nutrition-related complications was found between the two groups (P ＞ 0.05).Conclusion:In patients with gastric cancer,early sequential enteral nutrition can effectively accelerate the postoperative rehabilitation.

Objective:To investigate the effect of warmer intravenous infusion combined with local liquid dressing skin daub methods in short-term PN infusion patients with peripheral venous indwelling needle.Methods:Using the single blind random control method,150 PN patients from October 2015 to August 2016 were included.The control group was given the liquid dressing skin daub with 75 cases,and the observation group was given warmer intravenous infusion jointing local liquid dressing skin daub with 75 cases.To observe the incidence of phlebitis and the pain of the infusion catheter site with the infusion limb and the average maintain time of peripheral venous indwelling needle.Results:The incidence of phlebitis was significantly lower in the observation group than that in the control group (P ＜ 0.01) in two groups.The degree of infusion catheter pain with infusion limb pain wasless painful in the observation group than that in the control group (P ＜ 0.005) in two groups.The degree of catheter site pain after pulling out peripheral venous indwelling needle was less painful in the observation group than that in the control group(P ＜ 0.01) in two groups To compare the average maintain time of peripheral venous indwelling needle was (P ＜ 0.001)in two groups.Conclusion:Warmer intravenous infusion combined with liquid dressing skin daub can effectively prevent the occurrence of phlebitis in patients with peripheral venous indwelling needle PN infusion and improve the comfort.

Food intake has a great influence on blood glucose in patients with diabetes.This study was to determine the glycemic index (GI) and glycemic load (GL) of a particular pomelo named Majia pomelo and its effects on postprandial glucose (PPG) in patients with type 2 diabetes (T2D).Twenty healthy subjects and 20 T2D patients (controlled on lifestyle measures and/or metformin) were tested on 2 separate days with 50 g of glucose and 50 g equivalent of carbohydrates from Majia pomelo for GI measurement.To test effects of Majia pomelo on PPG,19 hospitalized T2D patients (controlled on insulin therapy) were selected for a 9-day study.The dose of insulin for each patient was adjusted on the first 3 days.A total of 100 mg Majia pomelo was consumed per meal in the last 3 tested days.Blood glucose was measured to evaluate the glycemic excursions.The GIs for Majia pomelo in healthy individuals and T2D patients were 78.34± 1.88 and 72.15±1.95 respectively.The value of GL was as low as 4.23 in diabetic patients with serving size of 100 g pomelo,indicting Majia pomelo as a high GI but low GL fruit.Consumption of Majia pomelo in hospitalized T2D patients did not cause significant glucose fluctuation.It was concluded that high GI pomelo can serve as a low GL fruit if it is consumed with a limited daily amount and thus can be supplied to diabetic patients.These results may mean more varieties of food choices for T2D patients.

Two control groups inhaled compound medications with single effective cough guidance. RE-SULTS:Compared with control groups,the patients in treatment groups eliminated more phlegm,had lower (PaCO2)and higher (PaO2),also had a shorter hospitalization period,with significant difference(P<0.05). CONCLUSIONS:Airway secretions expur-gation cluster management technology is a simple,safe and effective method,especially in patients with chronic obstructive pulmo-nary disease in oxygen-driven inhalation therapy.

OBJECTIVETo study the efficacy of self-made, antibiotic-loaded cement articulating spacer in the treatment of infected total knee arthroplasty.

METHODSThe self-made molds were used to form the spacer during the operation. From March 2002 to March 2007, 22 patients with infected knee arthroplasty (10 males with 10 knees, 12 females with 12 knees) were treated with this kind of spacer in our center. The mean age of the patients was 59.6 years old (33 to 75 years old). The interval time between primary arthroplasty and first onset of infective syndrome was 6.7 months (1 to 14 months). The diagnosis was established by the clinical presentation,serum laboratory inflammatory markers (white blood cell count,erythrocyte sedimentation rate and C-reactive protein) and knee aspiration. The serum laboratory inflammatory markers were used to measure the systemic response to infection. Clinical and radiographic follow-up was regularly performed by HSS score system and X-ray.

RESULTSAll the patients were followed, the average interval between debridement and reimplantation was 4.7 months (3 to 9 months) and the infection control rate was 100% after the implantation of spacer. The average follow-up duration after reimplantation was 29.8 months (10 to 64 months) and there was no recurrence of infection at the latest follow-up. The HSS score increased from 40.5+/-5.9 to 65.8+/-7.5 after the implantation of spacer, furthermore, the score reached 88.7+/-5.1 in average at the latest follow-up. The patient satisfaction rate was 95.3%.

CONCLUSIONThis self-made molds and spacers is a reliable approach for the management of infected knee arthroplasty with some virtues, such as providing a mobile and functional joint through the treatment course, decreasing the difficulty of reimplantation, avoiding of a long-term post-operative infusion and high effective for eradicating infection.

OBJECTIVETo study the clinicopathologic and immunohistochemical features, biological behavior, diagnosis and treatment of solid pseudopapillary tumor of the pancreas (SPTP).

METHODSA retrospective clinical and clinicopathologic analysis was made on 33 cases of SPTP admitted from May 2001 to 2010 July. There were 7 male and 26 female patients, aging from 13 to 66 years with a mean of 34.3 years.

RESULTSThe tumor was located in pancreatic head of 10 patients, in pancreatic neck of 5 patients, in pancreatic body and tail of 18 patients. Of the 33 patients treated with surgery, 8 underwent simple resection of pancreatic tumor, 6 underwent pancreaticoduodenectomy, 3 underwent tumor resection plus pancreaticojejunostomy, 1 underwent tumor resection plus pancreaticogastrostomy, 11 underwent distal pancreatectomy, 4 underwent distal pancreatectomy plus spleen resection (1 underwent mesohepatectomy for hepatic metastasis). Sixteen of the 33 operations were completed by laparoscopy. Histologically, tumors were composed of papillary and microcystic solid structures, with uniformed population of cells. The pancreas and blood vessels invasion were identified in 3 cases, one of them was combined with liver metastasis, and they are male. Immunohistologically, the tumors were positive for α1-antitrypsin, α1-antichymotrypsin, β-catenin, CD10, CD56 and vimentin (all cases), neuron-specific enolase (3 cases), synaptophysin (6 cases), chromogranin A (4 cases), progesterone receptor (28 cases), estrogen receptor (3 cases), S-100 (6 cases). Totally 33 cases were followed up with a median period of 49 months without tumor recurrence.

CONCLUSIONSSPTP is of low graded malignancy. It primarily affects young women. It may be located in any part of pancreas. Immunohistochemistry is very important for the diagnosis and differential diagnosis of SPTP. Surgical resection is recommended as the treatment of choice. Laparoscopic distal pancreatectomy or tumor resection is feasible and safe for some selected patients, and the prognosis is good.
