Objective To investigate the value of using gonadotropin-releasing hormone agonist (GnRH-a) pretreatment in adenomyosis patients before adenomyomectomy. Methods From May 2012 to September 2015, 87 patients with adenomyosis who were non-effective to conservative therapy in Renmin Hospital of Wuhan University were enrolled in this study. According to the principle of randomized control, 41 patients were in the treatment group who were treated with GnRH-a 2-3 cycles before adenomyomectomy, while 46 patients in the control group. The control group paients were operated without any pretreatments. The blood loss, the number of penetrating into uterine cavity, duration of operation, duation of peritoneal drainage and the amount of drainage fluid, the difference of hemoglobin value before and after operation, total white blood cell count, duration of hospitalization, the maximum diameter of uterus and other indicators between the two groups were compared. Results In the treatment group, before and after treatment with GnRH-a, the uterus size, blood hemoglobinand CA125 value were statistically different (all P<0.05);between the treatment group of GnRH-a treated for 2 cycles and for 3 cycles, there were statistical differences of blood hemoglobin value [(108 ± 20) versus (118 ± 24) g/L], CA125 value [(26 ± 11) versus(19 ± 4) kU/L; all P<0.05]. There were statistical differences of blood loss in operation [(113 ± 32) versus (194 ± 42) ml], ratio of penetrating into uterine cavity [12%(5/41) versus 12%(8/46)], duration of operation[(79±23) versus (91±25) minutes], duration of peritoneal drainage after operation [(2.1±0.9) versus (3.0±1.2) days] and the amount of drainage fluid [(152±43) versus (232±32) ml], the difference of hemoglobin value before and after surgery [(-15.6±2.9) versus (-23.7±3.5) g/L], white blood cell count after 2-3 days of operation [(11.4±4.2)×109/L versus (13.5 ± 3.2) × 109/L], ratio of peri-operative blood transfusion [5% (2/41) versus 20% (9/46)] and duration of hospitalization [(11.2±1.9) versus (13.6±3.1) days] between the treatment group and the control group (all P<0.05). Conclusion The pretreatment of using GnRH-a before adenomyomectomy in adenomyosis patients has benefits for implementation of surgery and reducing peri-operative and postoperative complications.

Previous work showed that there was high ratio of Mycoplasma hyorhinis infection in human gastric carcinoma. P37 protein is a membrane lipoprotein of Mycoplasma hyorhinis. It was reported that P37 inhibited cell adhesion and induced tumor invasiveness. To investigate the function of P37 in cancer development, the p37 gene was subcloned into shuttle vector of pAdTrack-CMV. Linearized pAdTrack-CMV-p37 was co-transformed into BJ5183 cells with adenoviral genomic plasmid pAdEasy-1. The identified recombinant DNA was transfected into 293 cells to package adenovirus. From the supernatant and cell lysis, the presence of recombinant adenovirus P37 was proved by PCR. And then BICR cells with this recombinant adenovirus of P37 were successfully infected. RT-PCR and Western blot demonstrated the transcription and expression of P37 in infected BICR cells. And the soluble P37 protein can be secreted into the culture supernatant of infected BICR cells. In the migration assay in vitro, the number of migration BICR cells infected with Ad-p37 was 52.03% more than that of control. The construction of recombinant adenovirus provided a good tool for studying P37 function and its molecular mechanism, which will be further used for in vivo migration and invasion experiments.

Objective To investigate the roles of iron ion in the development of experimental hydrocephalus in rats. Methods Seventy-five Sprague-Dawley female rats were divided into 3 groups randomly,that is,the iron group,the semi-iron group and the artificial cerebrospinal fluid (CSF) control group. FeC13 of 5 ?l dissolved in artificial CSF with the concentration of 6.67 g/L and 3.33 g/L were slowly infused into the right lateral cerebral ventricle of the rats in the iron group and in the semis-iron group respectively. The rats in the artificial CSF control group were infused 5 ?l artificial CSF. The rats were sacrificed 1,14 and 28 d later to measure the transverse diameter of the lateral ventricle for the evaluation of hydrocephalus and the index of ventricle,and pathology of brain was also observed. Results There were significant difference of hydrocephalus between the iron group (9/10) and the semis-iron group(1/5) at 28 d (P

Objective To inveatigate the effect of 15-HETE, a metabolite of arachidonic acid, on isolated hypoxic pulmonary arterial ringa ( PARs) , trying to find appropriate treatment for pulmonary hypertension and its complications during anesthesia in order to avoid hypoxemia. Methods Sixteen healthy Wistar rats of either sex weighing (230 ? 10) g were randomly divided into two groups : A control group breathing fresh air (FiO2 =21%) and B hypoxia group breathing hypoxic air (N2 = 90% , O2 = 10% ) in a hypoxic box. After breathing hypoxic air for 9 days the animals were anesthetized. Heart and lungs were immediately removed and PARs (0.5-1.0 mm in diameter and 3 mm in length) were prepared. Four PARs were prepared from each animal. The PARs were suspended in baths filled with Krebs-Hensleit (K-H) solution maintained at 37℃ and aerated with 95% O2 and 5% CO2. Preload was gradually increased to 0.3 g in 30 min. The isometric tension was measured using a four-channel force-displacement transducer. 15-HETE was added to K-H solution and the concentration was gradually increased from 10-8 to 10-6 mol?L-1 at 5 min intervals. Contractility of PARs was analyzed by a software of Medlab 6.0. Concentration-tension curve was drawn and contraction rates were calculated. 2 mmol?L-1 4-AP, 10-2 mol?L-1 TEA and 10-6 mol?L-1 GLYB were added to separate K-H solution baths and 40 min later 15-HETE was added in order to detennine the effect of difierent potassium channel blockers on contraction response of PARs to 15-HETE. Results With increasing concentration from 10-8 to 10-6 mol?L-1 , 15-HETE increased PARs tension gradually in a dose-dependent manner from 106% ?6% to 139% ? 4% in group A and from 113% ?6% to 163% ?6% in group B. The difference in PARs tension between group A and B was statistically significant (P

Objective To classify the essence of dampness obstructing spleen-stomach syndrome (DOSS) in rats and the effect of Huoxiang Zhengqi Oral Liquid (HZOL) on DOSS. Methods Comprehensive physical methods were applied to establish the rat DOSS model. Body weight, body length, tail length, abdominal girth index, and locomotor activity were observed. Moreover, a proton nuclear magnetic resonance (1H-NMR) based metabonomic approach was developed to profile DOSS-related metabolic perturbations in rat serum and feces and to investigate the intervention effect of HZOL in rats. Results Compared with the healthy control group, rats with DOSS showed weight loss, slow growth of body length, increased abdominal girth index, and decreased locomotor activity along with metabolic perturbations in serum and feces. The disturbed metabolic state associated with DOSS in rat serum and feces could be restored by HZOL. Meanwhile, six and eight potential biomarkers related to DOSS in rat serum and feces, respectively, were reversed by administration of HZOL. Conclusion The current study demonstrated that HZOL exerted protective effect against DOSS in rats, which was probably mediated by amelioration of disturbance in energy and amino acid metabolism and gut microbiota.
