Objective To investigate the indication and value of metallic stent in the management of patients with malignant obstructive jaundice(OJ). Method The clinical data of 15 patients with malignant OJ treated in our hospital were analysed retrospectively. All the 15 patients were treated with metallic stent including cholangiocarcinoma in 8 cases, carcinoma of gallbladder in 3 cases, pancreatic carcinoma in 2 cases, porta hepatis metastasis of gastric carcinoma after radical gastrectomy in 2 cases. Result All the patients' jaundice disappeared 11-38 days after the stent placement. No severe complications or death occurred in this series. One patient had cholimia 5 days after the stent placement, which was cured by non-operative method. All cases were followed up periodically, the survival time was 30-384 days(averag 180.5 days). Conclusions Installing stent of Titanium-Nickel metallic alloy for the patient with unresectable malignant OJ is an ideal palliative therapy which is simple and less discomfortable.and less complications.The effect of reducing jaundice is satisfactory. This method may offer a new alternative method in the management of malignant OJ.

Objective To study the effect of scalp acupuncture plus facilitation technique on the temporal and spatial parameters of gait in spastic cerebral palsy. Method Thirty eligible patients with spastic cerebral palsy were randomized into a treatment group and a control group based on the inter-group balance in age, palsy type, and the Gross Motor Function Classification System (GMFCS), 15 cases in each group. The treatment group was intervened by scalp acupuncture, together with the facilitation technique during the retaining of the needles; the control group was also by scalp acupuncture and facilitation techniques but with over 1 h interval between the two methods. The treatment was given once a day, totally for 3 months. The walking, running, and jumping items (E category) of the Gross Motor Function Measure-66 (GMFM-66), temporal and spatial parameters of gait, and vertical ground reaction force during stance were compared before and after the treatment. Result There were no significant inter-group differences in comparing the rates of E category of the GMFM-66 before the treatment (P>0.05), the rates were significantly changed after the treatment in both groups (P<0.05), and there were significant differences in comparing the rates between the two groups after the intervention (P<0.05);after the intervention, the step length, walking speed, and step frequency were increased significantly in both groups (P<0.05), while the double-stance phase was decreased significantly, and swing phase was increased significantly (P<0.05); after the intervention, the step length, walking speed, and step frequency of the treatment group were significantly better than that of the control group (P<0.05). Conclusion Acupuncture plus facilitation technique can mitigate the spasticity in spastic cerebral palsy, improve the gross motor function, especially the function of standing and walking, enhance the activities, and benefit the improvement of the step length, step width, and walk speed.

patients' survival up to November 2016.Survival curve was drawn using the Kaplan-Meier method.Survival and univariate analyses were done using the Log-rank test,and multivariate analysis was done using the Cox proportional hazard model.Results (1) Clinical features and results of assisted examinations:among the 322 patients,there were 301 patients with a chief complaint of jaundice.Of the 322 patients,the preoperative highest levels of TBil,DBil,ALT and AST in 322 patients were 3.9-785.2 μmol/L,1.6-410.2 μ mol/L,14.8-484.5 U/L and 21.4-539.8 U/L,respectively.Levels of ALP and GGT in 272 patients were 93.8-1 890.0 U/L and 2.0-1 832.8 U/L,respectively.Seventy-seven of 292 patients had an elevated CEA level,272 of 298 patients had an elevated CA19-9 level,153 of 260 patients had an elevated CA242 level and 86 of 260 patients had an elevated CA125 level.According to Bismuth-Corlette type,24 patients were detected in type Ⅰ,115 in type Ⅱ,55 in type Ⅲa,63 in type Ⅲb and 65 in type Ⅳ.(2) Treatments and results of pathological examination:Of the 322 patients,104 patients underwent radical resection,including 79 with hilar bile duct resection (9 combined with vascular resection and reconstruction) and 25 with extended hepatic lobectomy (16 combined with caudate lobectomy),and 218 patients underwent palliative treatments,including 134 with external biliary drainage and 84 with internal biliary drainage.Five patients were dead in the perioperative period,of which 2 died of acute liver failure,1 died of systemic infection and multiple organ failure,1 died of acute renal failure and 1 died of acute suppurative cholangitis,septic shock and disseminated intravascular coagulation.Of 263 patients receiving pathological examination,adenocarcinoma was detected in 253

in 132 patients,stage Ⅳ in 96 patients and indefinite stage in 33 patients.(3) Follow up and survival:among the 322 patients,296 were followed up for 12-132 months,with a median follow-up time of 65 months,including 94 with radical resection and 202 with palliative treatments.Among the 296 patients,the median survival time and 1-,3-,5-year survival rates were 10 months,47.1％,20.2％ and 9.5％,respectively.0f296 patients with follow-up,median survival time and 1-,3-,5-year survival rates were 31 months,84.0％,46.2％,25.0％ in 94 patients receiving radical resection and 7 months,29.9％,8.1％ and 2.3％ in 202 patients receiving palliative treatment,respectively,with a statistically significant difference between the 2 groups (x2=78.777,P＜ 0.05).Among the 94 patients receiving follow-up and radical resection,the median survival time and 1-,3-,5-year survival rates were 31 months,82.1％,45.1％,25.7％ in 73 patients undergoing hilar bile duct resection and 35 months,90.5％,49.8％,22.1％ in 21 patients undergoing hepatic lobectomy,respectively,with no statistically significant difference (x2=0.186,P＞0.05).Among the 73 patients undergoing hilar bile duct resection,median survival time and 1-,3-,5-year survival rates were 16 months,57.1％,0,0 in 7 patients combined with vascular resection and reconstruction and 34 months,84.6％,49.5％,27.5％ in 66 patients undergoing simplex hilar bile duct resection,respectively,showing a statistically significant difference (x2 =11.977,P＜ 0.05).(4) Prognostic factors analysis:results of univariate analysis showed that preoperative highest TBil,preoperative CEA,preoperative CA242,preoperative CA125,treatment methods and TNM staging were related factors affecting prognosis of patients with hilar cholangiocarcinoma (x2=25.009,18.671,9.359,33.628,94.729,77.136,P＜0.05).Multivariate analysis showed that preoperative highest TBil ≥ 342.0 μmol/L,preoperative CEA ≥ 5.00 μg/L,palliative treatments,TNM stage Ⅲ and Ⅳ were the independent risk factors affecting the poor prognosis of patients with hilar cholangiocarcinoma (HR =2.270,2.147,3.166,2.351,95％ confidence interval:1.587-3.247,1.446-3.188,2.117-4.734,1.489-3.712,P＜0.05).Conclusions Prognosis of hilar cholangiocarcinoma is still unsatisfactory.The R0 resection is the key in radical surgery.Preoperative highest TBil≥342.0 μmol/L,preoperative CEA ≥ 5.00 μg/L,palliative treatments,TNM stage Ⅲ-Ⅳ are independent risk factors affecting the poor prognosis of patients with hilar cholangiocarcinoma.

Objective:To study the factors influencing survival after radical resection in patients with intrahepatic cholangiocarcinoma (ICC), and to construct a nomogram on survival prediction.Methods:The clinical data of 139 patients with ICC who underwent radical resection at the People's Hospital of Zhengzhou University from June 2018 to December 2021 were retrospectively analyzed. There are 69 males and 70 females, aged (59.5±10.2) years old. These patients were divided into two groups based on a 3: 1 ratio by using the random number method: the test group ( n=104) and the validation group ( n=35). Data from the test group was used to construct a nomagram and data from the validation group was used to validate the predictive power of the nomagram. Univariate and multivariate Cox regression analyses were used to analyse factors influencing survival on the test group patients and to construct a nomogram. The predictive accuracy of the nomogram was determined by receiver operating characteristic (ROC) curves, concordance index (C-index) and calibration curves. Results:The results of the multivariate regression analysis showed that a combined hemoglobin, albumin, lymphocyte and platelet immunoinflammation (HALP) score <37.1 ( HR=1.784, 95% CI: 1.047-3.040), CA19-9 > 35U/ml ( HR=2.352, 95% CI: 1.139-4.857), poorly differentiated tumor ( HR=2.475, 95% CI: 1.237-4.953) and vascular invasion ( HR=1.897, 95% CI: 1.110-3.244) were independent risk factors that affected prognosis of patients with ICC after radical resection (all P<0.05). The AUCs of the nomogram in the test group in predicting the overall survival at 1, 2 and 3 years of patients with ICC after radical resection were 0.808, 0.853 and 0.859, respectively. There was good consistency between the prediction of the nomogram and actual observation. The predicted C-index of the total survival period of the test group was 0.765 (95% CI: 0.704-0.826), and the C-index of the validation group was 0.759 (95% CI: 0.673-0.845). Conclusion:A HALP score <37.1, CA19-9>35 U/ml, poorly differentiated tumour and vascular invasion were independent risk factors for prognosis of ICC patients after radical resection. The nomogram was established based on the above factors and showed good performance in predicting overall survival after radical resection in patients with ICC.

Objectives To evaluate the effectiveness and safety of peramivir trihydrate in patients with influenza.Methods This was a randomized,double-blind,double-dummy,placebo and positive control,multicenter clinical trial,comparing peramivir trihydrate with oseltamivir and placebo.The inclusive criteria were 15-70 years old,onset within 48 h,positive rapid influenza antigen test,and febrile(＞38℃) accompanied with at least two associated symptoms.The severe cases complicated with chronic pulmonary and cardiac diseases,malignancies,organ transplantation,hemodialysis,uncontrolled diabetes,immunocompromised status,pregnancy and coexistence of bacterium infections were excluded.All patients were randomized 2:2:1 to receive peramivir,oseltamivir and placebo respectively.The primary endpoint was the disease duration,the secondary endpoints included time to normal axillary temperature and normal living activities,viral response,and adverse effects.Results Following informed consent,133 patients were included in this study.Four patients were exclude due to missing medical records,not fitting inclusion or exclusion criteria and poor compliance.A total of 129 patients were finally analyzed,including 49 cases,54 cases and 26 cases in peramivir group,oseltamivir group and placebo group.The median disease duration were 96 (76,120)hours,105(90,124) hours,and 124 (104,172)hours in three groups respectively(P＞0.05).The time to normal axillary temperature,normal living activities and viral response were not significantly different in three groups(P＞0.05).Conclusion The value of antiviral therapy in patients with mild influenza needs to be further determined.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. A one-way 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 MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.
