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.

OBJECTIVETo optimize formulas of Quban gel.

METHODThe U6 (6(2) x 3) uniform design was adopted to optimize gel formulas, with rheological parameters, such as viscosity and yield value in room temperature, viscosity and yield value in average temperature of skin, thixlotropy.

RESULTThe optimum proportion of matrix was made of 1.0 g carbomer 940, 5 mL glycerin and pH value 5-6.

CONCLUSIONThe regression model for gel matrix quality and gel rheological parameters was established to directly reflect the impacting effect of various factors, and provide certain preference basis for the screening of gel matrix formulas. Quban gel prepared by the method was evenly distributed, moderately viscous and highly thixotropic

The multidisciplinary synthetic therapy for the colorectal liver metastases has been a hot spot in clinical research,which includes operative therapy,tumor local therapy,conversion therapy,chemotherapy, molecular targeted therapy and so on. It is need to choose multiple therapies for the patients and make the whole treatment strategy in accordance with the condition of patients to maximize the survival benefit in clinical prac-tice. So,it is important to comprehend the newest research process of the clinical therapy to make a good choice for the colorectal liver metastases patients.

Objective To investigate the effect of PARP inhibitor 3?aminobenzamide(3?AB)on cortical neurons in streptozotocin?induced diabe?tes mellitus(DM)rats and the mechanism. Methods A total of 60 rats were divided into 3 groups randomly:sham?operated control group,DM group and DM+3?AB group,20 rats in each group. Morris maze was used to detect learning and memory abilities in each group. Spectrophotometer assay was used to detect the levels of superoxide dismutase(SOD),glutathione peroxidase(GSH?Px)and malondialdehyde(MDA)in cortex. West?ern blot was used to determine the expression of poly(ADP?ribose)polymerase 1(PARP1)in cortex. Immunohistochemical staining was used to de?termine the expression of caspase?3?immunoreactive neurons in cortex. Results DM rats showed significantly declined learning and memory abili?ties. Compared with the control group,the levels of SOD and GSH?Px were significantly reduced(P<0.01)and the level of MDA was significantly up?regulated(P<0.01)in the DM group. Compared with the DM group,the levels of SOD and GSH?Px were significantly higher(P<0.05)and the level of MDA was significantly lower in the DM+3?AB group(P<0.05). The expression level of PARP1 was significantly up?regulated in the DM group and was significantly decreased in the DM+3?AB group(P<0.01). The level of caspase?3 was significantly higher in the DM group than in the control group(P<0.01),and was significantly decreased in the DM+3?AB group(P<0.01). Conclusion 3?AB protected cortical neurons from apoptosis in DM rats by inhibition of PARP1 and alleviation of oxidative stress.
