Objective: The aim of this study was designed to certify the effects of substance P(SP) on thermo-gonohormonal neuron. Methods: We used the technique of extracellular microelectrode recording, and examined the effects of intravenously injections of SP on electroactiveties of thermo-gonohormonal neurons in PO/AH of rats. Results: Total of 9 warm-estradiol sensitive and 4 cold-estradiol sensitive neurons were recorded in PO/AH, where estradiol excited electroactivities of the warm-estradiol sensitive neurons but inhibited those of the cold-estradiol sensitive ones. While SP reversed the effects of estradiol bezonate on the above mentioned neurons. Conclusion: From our results and related data we may draw conclusions that the thermoregulatory effects of SP may be functioned via hermo-gonohormonal neuron.

Objective:To compare the clinical and imaging characteristics between central nervous system vasculitis(CNSV)and mitochondrial encephalomyopathy(ME),so as to analyze the differential diagnosis of the two disorders.Methods:Clinical data on seven patients with CNSV and five with ME were retrospectively analyzed.The clinical manifestations,laboratory parameters,imaging features and histological characteristics were compared to screen for the evidence of their differential diagnosis.Results:The MRI results of both CNSV patients and ME patients(MELAS type)showed a multi-lesion pattern.The symptoms of CNSV patients included headache,limbs weakness,and erythrocyte sedimentation rate(ESR)increase.The symptoms of MELAS patients included epilepsy and increased serum lactic acid.The electroencephalographic manifestations of both diseases were abnormal:CNSV patients mainly had diffused lesions accompanied with limited alterations;ME patients had evidence of epileptic discharge,which was consistent with the clinical symptoms.Conclusion:Clinical manifestations of CNSV and ME patients are more valuable than imaging findings in the diagnosis of the two diseases.CNSV is characterized by vascular disorders and inflammatory reactions;ME is characterized by abnormal energy metabolism and severe damage of gray matter.The final diagnosis should depend on laboratory and histological examinations.

ObjectiveTo study the clinical characteristics of the temperature instability in Prader-Willi syndrome (PWS). MethodsThe clinical characteristics of one case of PWS with recurrent fever were retrospectively analyzed.ResultsA 5-month-old boy who had such clinical characteristics as low central muscle tension, sucking weakness, feeding dififculties, cryptorchidism and white skin was diagnosed as PWS by chromosomal microarray analysis and methylation-speciifc PCR. In the course of the disease, the infant presented recurrent fever. The pathogenic bacteria culture and virus antibody detection showed negative, and the treatment of reducing fever, anti-infection and immune support were ineffective.ConclusionsThe cause of the recurrent fever is unknown and central fever is suspected. Whether the temperature instability is the clinical feature of PWS still needs a lot of clinical researches.

Diabetic nephropapthy (DN) is a common cause of end-stage renal disease.Early diagnosis and treatment are significant for delaying the development of DN.Smad proteins mediate transforming growth factor β superfamily intracellular signal transduction.Recent studies have found that Smad1 protein plays an important role in the process of renal fibrosis.Urine Smad1 emerges in the early stage of DN,which is expected to be a non-invasive indicator in early diagnosis of DN.

Objective To investigate the risk factors for deep vein thrombosis (DVT) of lower limbs after laparoscopic surgery.Methods A total of 230 patients underwent laparoscopic surgery were selected in Huanggang Central Hospital from January 2014 to August 2016.The patients were divided into DVT group and non-DVT group according to DVT of the lower limbs,and the related risk factors for DVT of lower limbs after laparoscopic surgery were analyzed.Results In the 230 patients,there were 10 patients with DVT of lower limbs and 220 patients without DVT of lower limbs,the incidence of DVT of lower limbs was 4.35％ (10/230).Logistic regression analysis showed that age ≥40 years old,operation time ≥120 min,postoperative ambulation time ≥ 30 h,the intraoperative position of high-head and low-foot,plasma D-Dimer level ≥0.5 mg · L-1 were the independent risk factors for DVT of lower limbs after laparoscopic surgery (P ＜ 0.05).Conclusion There is a certain incidence of DVT of the lower limbs after laparoscopic surgery.The effective prevention measures should be taken to reduce the incidence of DVT after laparoscopic surgery according to the related factors of DVT.

ObjectiveTo discuss effective measures to improve postoperative sexual life quality of patients with cervical intraepithelial neoplasia (CIN).MethodsOne hundred and twenty patients with CIN were randomly assigned to the blue-ribbon club group, the friendship-support group and the control group. The blue-ribbon club patients were regarded as club members and received special education every two months. The friendship-support group patients received education one by one in the hospital setting and the control group patients received the same education as before participated into the trial. Female sexual function index (FSFI)was used to evaluate sexual function before and 6 months after intervention.ResultsExcept sexual pain, the total score of FSFI and the score of sub-domain in the blueribbon club were significantly higher than that in the control group. The total score of FSFI and score of sub-domain were significantly higher than that in the control group. There were no significant differences between both intervention groups.ConclusionsBoth education intervention modes of the blue-ribbon club group and the friendship- support group could effectively improve sexual function for post-operation patients with CIN.

BACKGROUND: Whole body vibration which is used to prevent and treat osteoporosis recently is uncomfortable due to its strong vibration strength. The designed compound vibration with low vibration strength could effectively prevent bone quality decrease of ovariectomized rats. OBJECTIVE: To verify the effect of compound vibration with low vibration strength on the bone quality of ovariectomized rats. METHODS: A total of 32 4-month-old female SD rats were used in this study. All SD rats were randomly dlvided into 4 groups: normal control group, ovadectomized control group, vibration Ⅰ group (45 Hz-55 Hz, 0.05 g-0.1 g), and vibration Ⅱ group (45 Hz-55 Hz, 0.12 g-0.21 g), with8 rats for each group. The intervention to each vibration group was onea day, 20 minutes/tlmes and 5 days per week. The resting interval was shorted than 2 days, and the whole vibration intervention lasted 13 weeks. Bone mineral density (BMD) before and after vibration, ex vivo bone microstructure parameters and biomechanics parameters ware measured in this study. RESULTS AND CONCLUSION: Lumbar BMD of ovariectomized control group was decreased (P < 0.05), but the BMD in the normal control group and the two vibration groups was increased significantly. Femoral BMD of all groups was increased, but there was no significant difference among the four groups. Bone microstructure parameters of the three ovariectomized groups ware decreased; however, parameters including number, thickness and distance of bone trabecula and bone volume fraction in the vibration Ⅱ group were significantly improved compared to ovadactomized control group. Moreover, bone strength of lumbar vertebra in the two vibration groups was significantly increased (P=0.025, 0.006), but there was no significant difference compared to normal control group. Compound vibration with low strength could effectively prevent BMD decrease of ovadectomized rats, lighten the dagrea of bone microstructure damage, keep bone strength, improve bone quality of ovadectomized rats, and potentially prevent osteoporosis.

BACKGROUND: Clinical experiments indicates that Yufeng capsule (composed of milkvetch root, angelica, szechwan lovage rhizome, senega and salvia miltiorrhiza) is effective for benefiting vital energy, circulating blood flow,dispelling gores and killing inflammation. The mechanism may be associated with the function of platelet aggregation, changes of contents of thromboxane B (TXB) and 6-Ketoprostaglandin F1 alpha (6-keto-PGF1 α) in plasma.OBJECTIVE: To observe the influence of Yufeng capsule on the platelet aggregation and its mechanism.DESIGN: Randomized controlled animal trial.SETTING: Department of Pathology, Daqing Branch of Harbin Medical University.MATERIALS: The experiment was performed at the Laboratory of Pharmacology, Daqing Branch of Harbin Medical University from May 2000 to July 2004. A total of 40 Wistar male gerontic rats with mean age of (8-10) weeks and mean body mass of (550±150) g and 8 Wistar male young rats with mean age of 4-6 weeks and mean body mass of (230±120) g were selected.METHODS: The 8 Wistar male youth rats were selected as youth control group. The 40 Wistar male gerontic rats were selected as the blood stasis model, and according to the numeration table method they were classified into 5 groups: aspirin group, low-dose Yufeng capsule group, the middle-dose Yufeng capsule group, high-dose Yufeng capsule group and gerontic model group, with 8 rats in each group. The Yufeng capsule was constituted by milkvetch root, angelica, szechwan lovage rhizome, senega and salvia miltiorrhiza, and provided by the Preparation Office, Second Affiliated Hospital,Heilongjiang University of Chinese Medicine. Respectively the rats were injected with aspirin solution (5.5 g/kg), Yufeng capsule (0.33 g/kg, 0.66 g/kg and 1.32 g/kg), successively for 22 days by gastric perfusion, twice a day.Those in the gerontic group and youth control group were not treated with any drug One hour after last time administration, function of platelet aggregation(PAG), contents of thromboxane B2 (TXB2) and 6-Ketoprostaglandin F1 alpha (6-keto-PGF1 α) in plasma were examined with platelet aggregation method and radioimmunoassay.MAIN OUTCOME MEASURES: Function of platelet aggregation; contents of TXB2 and 6-keto-PGF1 α as well as ratio of TXB2 to 6-keto-PGF1α.RESULTS: Totally 48 animals were involved in the result analysis. ①The PAG was higher in the gerontic model group than other groups (P ＜ 0.01).②One minute platelet aggregation rate (PAG1), five minutes platelet aggregation rate (PAG5)and the maximal platelet aggregation rate (PAGM) in the high-dose Yufeng capsule group were lower than those in the aspirin group[(7.96±2.17), (6.38±1.66), (14.33±2.87) ng/L and (31.95±3.94),(35.29±6.54), (38.68±7.46) ng/L, respectively(P ＜ 0.01 )]. PAG5 in the middle-dose group was lower than that in the aspirin group [(13.96±1.66),(35.29±6.54) ng/L, (P ＜ 0.01 )]. ③TXB2 content in the low-dose Yufengcapsule group, middle-dose Yufeng capsule group, high-dose Yufeng capsule group, aspirin group and youth control group was lower than that in the gerontic model group (P ＜ 0.01). ④The TXB2 content in the high-dose Yufeng capsule group was lower than that in the low-dose Yufeng capsule group [( 100.13±8.90), (127.00±20.99) ng/L, (P ＜ 0.01 )]. ⑤TXB2/6-ke-to-PGF1 α in the high-dose Yufeng capsule group, middle-dose Yufeng capsule group and youth control group was lower than that in the gerontic model group [0.62±0.17,0.69±0.14,1.75±0.17,1.11±1.12, (P ＜ 0.05 )].CONCLUSION: High-dose and middle-dose Yufeng capsule is able to decrease the content of TXB2 and increase the content of 6-keto-PGF1 α, and improve their ratio. It is important to enhance the balance of TXB2 and 6-keto-PGF1 α. The effect in the low-dose Yufeng capsule group is lower as compared with that in the high-dose and middle-dose Yufeng capsule groups. It is thought that the low-dose Yufeng capsule has preventive effect.
