Chinese Journal of Primary Medicine and Pharmacy 2015;(11):1712-1715
Objective To investigate the antiviral treatment for patients with chronic hepatitis c(CHC)the influence of thyroid function and its related risk factors.Methods Used polyethylene glycol (peg) interferon (PegIFN α-2a)plus ribavirin (RBV)for the treatment of 122 cases of patients with CHC data were retrospectively analyzed.All of the patients before treatment thyroid function were normal.According to the thyroid function after treatment they were divided into normal thyroid function and abnormal thyroid function groups.Adopting the method of case -control study and Logistic regression we analyzed correlative risk factors of thyroid dysfunction.Results 122 CHC patients completed 48 weeks of treatment,and follow -up of 24 weeks,34 patients with thyroid dysfunction,rate of 27.9%. Logistic regression analysis showed that women,a positive thyroid autoantibodies,health care and smoking might be risk factor for thyroid dysfunction(OR =4.470,4.470,4.757 and 7.306,P <0.05 or P <0.01).Conclusion Inter-feron plus RBV during the treatment of CHC patients with a high incidence of thyroid dysfunction,including women,a positive thyroid autoantibodies,the health,and smoking could be a risk factor for thyroid dysfunction.

Objective To investigate the characteristics and risk factors of occupationai exposure to bloodborne pathogens among health care workers (HCWs),and evaluate prevention and treatment countermeasures.Methods Record Form for Occupational Exposure to Bloodborne Pathogens Among Health Care Workers was used for retrospective survey on the occurrence of occupational exposure to bloodborne pathogens in a hospital between January 1,2013 and December 31,2015.Results A total of 246 cases of blood/body fluid occupational exposure occurred.The main occupational exposure population were nurses (n =95,38.62%);occupational exposure mainly occurred in wards(n =148,60.16%);the main mode of occupational exposure was sharp injury(n =219,89.02 %);the main opportunity of occupational exposure of HCWs was surgical accident(n =69,28.05 %);the main exposure source was hepatitis B virus(n =123,50.00 %);none of HCWs developed infection after local treatment and prophylactic medication.Conclusion Medical institutions should strengthen the training for HCWs about occupational exposure to bloodborne pathogens,enhance protection awareness,standardize operation procedures,and improve working environment,so as to minimize the occurrence of occupational exposure.

In order to study the involatile chemical components in Moutai-flavored distiller’s grains, the Moutai-flavored distiller’s grains were extracted with 75% ethanol, followed by extraction with petroleum ether, ethyl acetate, and n-butanol. Silica gel, ODS, sephadex LH-20, and preparative HPLC were used to separate and identify the petroleum ether and ethyl acetate layers.ESI-MS and NMR were used to identify the compounds, which were respectively identified as pentadecanoic acid (1), palmitic acid (2), trans-2-decenoic acid (3), n-nonyl octadecanoate (4), ethyl octadecanoate (5), ethyl linoleate (6), luric acid (7), 1, 3-dicaprylyl-2-linoleylglycerin (8), cyclic (phenylalanine-proline) (9), cyclo-(proline-leucine) (10), 3, 6-bis-(2-methylpropyl)-2,5-dione piperazine (11), 4-hydroxyphenethyl alcohol (12), 2,4-dihydroxybenzoic acid (13), stigmasterol (14), 2-furancarboxylic acid (15), valine (16), L-alanine acyl-L-proline (17), dihydroquercetin (18), 5, 7, 3'', 4''-tetrahydroxyflavonoids (19), quercetin (20), and naringenin (21). Compounds 1-21 were isolated from distiller’s grains for the first time.

Pancreatic cancer is the fourth leading cause of cancer-related death in the world.Most patients are diagnosed as locally advanced or metastatic disease at initial visit,losing the opportunity of surgery.Conversion therapy aims to give unresectable tumors the opportunity to receive radical surgery through comprehensive treatment.For unresectable pancreatic cancer,chemotherapy based on AG(abraxane+gemcitabine)or FOLFIRINOX(5-fluorouracil+leucovorin+irinotecan+oxaliplatin),radiotherapy combined with chemotherapy as well as other regimens have shown conversion potential.Targeted therapy and immunotherapy have also become new frontiers of conversion therapy for pancreatic cancer.Focusing on new drugs and new regimens,this review has summarized the latest research progress of conversion therapy for pancreatic cancer.

ObjectiveTo investigate the population with an advantage of clinical cure previously treated with nucleos(t)ide analogues (NAs), and to provide more methods for clinicians in pursuing the clinical cure of hepatitis B. MethodsA total of 42 chronic hepatitis B patients with low-level HBsAg who received NAs treatment in Hebi Third People’s Hospital from October 2017 to October 2019 were enrolled as subjects and divided into combination treatment group (group A) and NA monotherapy group (group B). The 22 subjects in group A were treated with NAs combined with PEG-IFN antiviral therapy for 48 weeks, and some patients withdrew from PEG-IFN after 24 weeks and continued to receive NA monotherapy, while the 20 subjects in group B received NA antiviral therapy alone. Both groups were observed till week 48, and the five makers for hepatitis B were measured to evaluate clinical outcome. The t-test was used for comparison of continuous data between two groups, and the Fisher’s exact test was used for comparison of categorical data between two groups; a multivariate logistic regression analysis was used to perform a multivariate analysis. ResultsCompared with group B at the 48-week treatment endpoint, group A had significantly higher HBsAg clearance rate (45.5% vs 0, P<0.01) and HBsAg seroconversion rate (31.8% vs 0, P<0.01). The population with HBsAg <1000 IU/ml, <500 IU/ml, <100 IU/ml, and <10 IU/ml had an HBsAg clearance rate of 52.6%, 61.5%, 66.7%, and 100%, respectively, and the population with an HBsAg level of 500-1000 IU/ml, 100-500 IU/ml, 10-100 IU/ml, and <10 IU/ml had an HBsAg clearance rate of 33.3%, 50%, 40%, and 100%, respectively. The 4 patients with baseline HBsAg <10 IU/ml (accounting for 18.2% in group A) achieved clinical cure at week 12 of combined treatment, and after observation to week 48, 2 patients had an anti-HBs level of >100 IU/ml and 2 had an anti-HBs level of >1000 IU/ml. The multivariate logistic regression analysis of HBsAg clearance showed that age at the initiation of combined treatment affected HBsAg clearance (odds ratio [OR]=0.877, 95% confidence interval [CI]: 0.781-0.985, P=0.026), and most of the patients with HBsAg clearance had an age of 36-49 (44.20±4.49) years; baseline HBsAg level also had an impact on HBsAg clearance (OR=0.996, 95% CI: 0.992-1.000, P=0.050). ConclusionThe addition of interferon therapy in chronic hepatitis B patients with low-level HBsAg previously treated with NAs can significantly improve the clinical cure rate. The younger the age and the lower the HBsAg level, the shorter the duration of combined treatment. Age and baseline HBsAg level are more important than the duration and type of NA medication.
