Objective To explore the therapeutic effect of loop electrosurgical excision procedure (LEEP)in the treatment of patients with cervical intraepithelial neoplasia (CIN) and its influence on pregnancy outcome.Methods 62 women with CIN who underwent LEEP were selected as treatment group,and 63 women with CIN who did not undergo LEEP in the same period were selected as control group.Then the curative effect and the pregnancy outcome were observed.Results The total effective rate was 93.65％ in the treatment group and 76.19％ in the control group,the difference was significant (x2 =7.034,P ＜ 0.01).The operation blood loss,operation time and the day of colporrhagia after operation in the treatment group were less than those in the control group(all P ＜ 0.05).There were no significant differences in the gestational age,incidence rates of abortion and cesarean section between the two groups (all P ＞ 0.05),while there were significant difference in the incidences of preterm delivery,premature rupture of membrane and low birth weight infant (all P ＜ 0.05).Conclusion LEEP is an effective treatment for patients with CIN,which can increase the incidence rates of preterm delivery,premature rupture of membrane and low birth weight infant,but not increase the gestational age,incidence rates of abortion and cesarean section.

[Objective] To investigate the effect of Ruangan Kangxian Prescription (RKP), a prescription mainly composed of Radix Salviae Miltiorrhizae, Radix Paeoniae Rubra, Catechu, Radix Stephaniae Tetrandrae and Polyporus, for rats liver fibrosis induced by carbon tetrachloride (CC14) and to explore its mechanism. [Methods] Rats with liver fibrosis were induced by CC14 and were randomized to RKP group, normal group, Biejia Ruangan Tablet (BRT) group and model group. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) , procollagen Ⅲ (PCⅢ ) were detected; hepatic histopathology and immunohistochemical result of transforming growth factor ?1 (TGF ?1 ) were also examined. [ Results ] Death rate of rats was reduced; serological parameters of hepatic function and liver fibrosis were improved and liver fibrosis showed by immunohistochemical method, HE staining and Masson staining was inhibited in RKP and BRT groups (P 0.05). [ Conclusion ] RKP and BRT have the similar effect in preventing CC14-induced liver fibrosis in rats and its mechanism may be related to the counteraction of expression of TGF ?1 .

Objective: To investigate the effects of the cyclic uniaxial compressive stress on RKIP and its mRNA in the rat condylar chondrocytes. Methods:The third-passage chondrocytes were harvested from the mandibular condyles of 2-day-old rats, and a cellular compressive stress device (self-made four-point bending system. Patent No: 01129166.4 & 01256849.x) was used to apply stress on cells at 4 000 ?strain ( 0.5 Hz frequency) for 0, 15, 30, 60, 120 and 240 min. The effects of the cyclic uniaxial compressive stress on RKIP and its mRNA in the rat mandibular condylar chondrocytes were examined by REAL-TIME PCR and Western blot. Results:The results showed that the expression of RKIP and its mRNA changed obviously with 4 000 ?strain compressive stress loading, there are reverse tendency in the expression between RKIP and its mRNA. RKIP mRNA significantly increased at 30min (P

Previous studies have agreed that the levels of neuron-specific enolase (NSE)and S100B protein have an important value for the severity of cerebral infarction and prognosis estimation. This article reviews the relationship between the serological changes of NSE and S100B and cerebral infarction, infarct volume, severity of neurological deficits, infarct location,and prognosis, as well as the advances in research on the evaluation of therapeutic drugs.

Objective To evaluate the performance of an improved skin prick test in infantile eczema.Methods A self-controlled study was carried out in 248 infants with eczema.Improved and conventional skin prick tests were conducted with 8 allergens on the left and right flexural forearm of the subjects,respectively.Results Positive results of skin prick test were found in the left flexural forearm of 38.3％ of the infants,and in the right flexural forearm of 38.7％ of the infants,with no significant difference between the two methods in the detection rate of allergens (P ＞ 0.05).The most common sensitizing allergens were house dust mite and Dermatophagoides culinae as shown by both methods.Conclusions The improved skin prick test displays an acceptable performance with simple and safe procedure in the detection of allergens in infants with eczema,and can provide reliable evidence for clinical diagnosis.

Objective To analyze the effect of iodine-131I in the treatment of patients with hyperthyroid heart disease(HHD).Methods The clinical materials and therapeutic effect by 131 I were reviewed in 100 patients with HDD.Results The heal rate of hyperthyroidism and HHD were 82.3％,86.5％ in treatment group,and were higher than that of the control group (69.0％ and 76.2％ ) ( x2 =3.80,3.83,P ＜ 0.05 ) ; HHD with atrial fibrillation was 65.0％,average cardioversion after 131I treatment was 74.4％ after the treatment by 131I;The LVEDD、LVESD、LVEDV and HR after 131 I treatment were lower compared with before treatment ( all P ＜ 0.05 ),SV and EF were increased ( all P ＜ 0.01 ).Conclusion 131I treatment in patients with HHD,can significantly improve the efficacy of a heart disease

Radiotherapy is the primary treatment for nasopharyngeal carcinoma, and the disease control rate and survival time are able to be greatly improved by enhancing the radiosensitivity. Via mechanisms such as binding to target genes mRNA 3'untranslated region (3'UTR), microRNA (miRNA) inhibits translation, which therefore regulates transcription of target genes and thus affect target protein expression. Recent research showed that miRNAs play significant roles in improvement of radiosensitivity in nasopharyngeal carcinoma. This article reviews mechanism of miRNA action to strengthen radiosensitivity of nasopharyngeal carcinoma and the future of clinical practice of miRNA in this disease.

OBJECTIVE: To evaluate the clinical efficacy on the treatment of the low-middle frequency sudden hearing loss with postaurical injection of methylprednisolone. METHOD: The 80 cases of the low-middle frequency sudden hearing loss were randomly divided into postaurical injection and oral hormone groups. The postaurical injection group (42 cases) received the postaurical injection of methylprednisolone, 40 mg/2 d, combined with the treatment of Ginkgo dipyidamolum and Alprostadil for 14 d; The oral hormone group (38 cases) received the oral prednisone, 1 mg/kg/d, administrated once on the morning for 3 d, if effective, prolonging for another 2 d, as mentioned above for Ginkgo dipyidamolum and Alprostadil. RESULT: The total effective rate was 88.10% in postaurical injection group and 86. 4o%in oral hormone group. There was no significant difference between the twbogroups( P> 0. 5). CONCLUSION Postaurical injection of methylprednisolone for the low-middle frequency sudden hearing loss is effective, safe and simple, which may be an alternative for systemic administration of gulcocorticoid.

Objective To learn the awareness rate of HIV/Syphilis knowledge,condom usage,group behaviors and the infections among men who have sex with men (MSM)in Zhuhai and provide scientific foundation for preparing control measures.Methods The internet community was used for calling MSM to join the research.A MSM survey questionnaire was used to collect messages in the place of HIV Voluntary Counseling & Testing(VCT).The blood samples were collected to proceed biological detection.Re-sults Total 247 MSMs were tested,positive rates of HIV,TP specific antibody and non-specific antibody were 8.10% (20/247), 13.36%(33/247)and 10.72% (24/247).The separation between cognition and behavior was common existed in such population. HIV/syphilis infection rates were significant different between MSMs who had multiple sexual partners and those who did not. Conclusion Because the high risk behaviors are commonly existed among MSM in Zhuhai,the prevalence rates of HIV/Syphilis in them are high.It is necessary promote the screening of HIV/Syphilis,enhance the health education of disease control and block the transmission to develop a safe awareness and behaviors in MSM.
