Objective:To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism.Methods:A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated.Results:The age of onset year of the 40 patients (male: female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT 4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions:Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT 4 is a crucial factor affecting the efficacy of octreotide.

Spermiogenesis is a complex process of differentiation and morphologic alteration, in which sperm acrosome formation is an important stage. Acrosome is an essential component of the sperm head, which develops in four distinct phases: Golgi, cap, acro- somal, and maturation, each supported by precise and orderly regulation of various genes. The regulatory genes which act on Golgi ap- paratus include GOPC, Hrb, SPATA16, PICK1, and CK2α', those involved in the cap phase are Fads2, syntaxin 2, Kdm3a, and UBR7, and participating in acrosomal and maturation phases are KIFC1, Rnf19a, and DPY19L2. The abnormalities of these genes may affect male fertility by influencing the connection of the nuclear dense lamina and acroplaxome with the nuclear membrane and then the fusion and transportation of vesicles. This review focuses on the genes involved in different phases of acrosome formation.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

Objective To evaluate the drill method to prepare for healthcare-associated infection (HAI)outbreak, and strengthen the control of HAI outbreak.Methods According to two cases of surgical site infection (SSI)re-ported by a neurosurgical department on January 16,2014,HAI outbreak emergency drill was started,SSI occurred from January 2012 to January 2014 were analyzed,specimens of air,object surface and hands of health care workers (HCWs)in the SSI-related operating room and neurosurgical intensive care unit(NSICU)were taken and analyzed. Results In July 2013,3 cases of SSI occurred in neurosurgical department (1 case was suspected of SSI,and didn’t per-form cerebrospinal fluid culture),SSI didn’t exceed 2 cases in the other months,and SSI outbreak couldn’t be confirmed. 16 specimens of air,object surface and hands of HCWs in operating room were taken,microbial detection results were all qualified.13 specimens of air,object surface and hands of HCWs in NSICU were taken,qualified rate was 61.54%;and mould was detected from 2 air specimens.24 disposable objects of neurosurgical department were performed bacterial cul-ture,3 were positive,and all were qualified after repeated detection.Conclusion HAI outbreak drill is helpful for HAI management professional personnel to grasp the method of HAI outbreak investigation method,improve the correct hand washing of surgeons and nurses,strengthen the standard operating procedure,and ensure the safety of pa-tients.

OBJECTIVETo compare therapeutic effects of penetration needling at the back and western medicine on fibromyalgia syndrome (FS).

METHODSThirty-eight cases were randomly divided into the observation group treated with penetration needling at the first and second lines of The Bladder Meridian of Foot-Taiyang and Governor Vessel, and the control group treated mainly with oral administration of amitriptyline, 19 cases in each group.

RESULTSThere were significant differences in the cured-markedly effective rate and the results of follow-up for 6 months for the cured-markedly effective cases between the observation group and the control group (all P < 0.01).

CONCLUSIONPenetration needling therapy in the therapeutic effect on fibromyalgia syndrome is better than the medical treatment.

To observe the alteration in the expression of DNA repair enzymes hOGG1 and hMYHalpha and the change in 8-OHdG levels in the HBx gene-transfected cells HepG2/HBx and to explore the mechanisms of the HBV-associated hepatocellular carcinoma, the gene-transfected cells HepG2/HBx which stably expressed HBx was established, and the effect of HBx on the cell cycle and proliferation of HepG2 was examined. By using the beta-actin as the interior control, real-time polymerase chain reaction (Real-time qPCR) was employed to quantitatively detect the expression of DNA repair enzymes hOGG1 and hMYHalpha in the HepG2/HBx, the control cells HepG2 and HepG2 transfected with pcDNA3.1 vector (HepG2/pDNA3.1). The 8-OHdG levels were determined by HPLC/ECD in the established gene-transfected cells HepG2/HBx and the control cells HepG2 and HepG2/pcDNA3.1. Our results showed that the expression of DNA repair enzyme hMYHalpha in the HepG2/HBx (0.021+/-0.007) was significantly lower than that of HepG2 (0.099+/-0.041) (P<0.05) and HepG2/pDNA3.1 (0.121+/-0.005) (P<0.05). However, the no significant differences existed in the expression of DNA repair enzyme hOGG1 among the three cell strains (P>0.05). The 8-OHdG level in the HepG2/HBx was significantly higher than that in HepG2 and HepG2/pcDNA3.1 (P<0.05). It is concluded that HBx gene may inhibit the expression of DNA repair enzyme hMYHalpha mRNA to impair the ability to repair the intracellular DNA oxidative damage, to increase the oxidative DNA-adduct 8-OHdG and to affect the nucleotide excision repair function, thus participate in the occurrence and development of hepatocellular carcinoma.

The IS-PCR and Rep-PCR were used to analyze 19 strains of Xanthomonas oryzae pv.oryzae from China,Japan and Philippines.Four specific primers,especially,IS1113 and ERIC could distinguish the strains from different countries.Using UPGMA analysis,most strains were in group 2 and 3.No relationship were observed between UPGMA groups and pathotypes.

Eleven type 1 diabetic patients who received fixed regime of insulin Glargine were included in the study.The levels of fasting serum insulin were measured for each subject at 6:00 in three consecutive mornings.The variability of mean fasting serum insulin in each subject was 3.3%-41.5% (mean 15.4%).The variability did not correlate with the dose of Glargine statistically.
