Objective To explore the association of tumor necrosis factor(TNF)-α gene-308G/A single nucleotide polymorphism with susceptibility to syphilis.Methods The study includes 56 patients with early symptomatic syphilis,38 with eady latent syphilis,and 102 normal human controls.The-308G/A single nucleotide polymorphism of TNF-α gene was detected in all subjects by real-time fluorescent quantitative PCR.Results The frequency of TNF-α-308 G and A allele was 0.926 and 0.074 in patients with early syphilis,0.941 and 0.059 in the controls,0.929 and 0.071 in patients with early symptomatic syphihs,0.921 and 0.079 in patients with early latent syphilis.No significant difference was found between patients with early syphilis and the controls or between patients with early symptomatic syphilis and those with early latent syphilis in the frequency of either allele (MG) at-308 position of TNF-α gene(all P>0.05).Conclusion There seems to be no evidence for association between TNF-α gene-308G/A single nucleotide polymorphism and susceptibility to syphilis.

Objective To observe the blocking efficacy of mother to child transmission (MTCT) in pregnant women with positive human immunodeficiency virus(HIV), and explore proper MTCT blocking mode for acquired immunodeficiency syndrome.Methods Clinical data of 23 HIV-positive pregnant women in a hospital from 2005 to 2015 were retrospectively analyzed.Results All 23 HIV-positive pregnant women received highly active antiretroviral therapy (HAART) and comprehensive intervention for blocking MTCT of HIV.Among these women, 12 got pregnant after receiving HAART, 10 were detected positive HIV in early pregnancy (within 28 weeks) and then received HAART, 1 was detected positive HIV 28 weeks after pregnancy and then received HAART.23 HIV-positive pregnant women all delivered normal newborns, follow-up observation of babies found no HIV infection.Conclusion HAART for HIV-positive pregnant women is the key to block MTCT of HIV, combined with preventive medication and artificial feeding of newborns, HAART can effectively prevent MTCT.Mutual blocking mode, such as HAART for HIV-positive pregnant women by specialists, pregnancy check-up, and preventive medicine for infants provided by maternity and child care hospital, is highly efficiency.

Objective To evaluate transurethral endosco pic management of 15 cases of ureterocele encountered between 1990 and 2000. Methods All the medical documents were reviewed and analyse d. Results The diagnosis of all the cases was establishe d on IVU,ultrasonography and endoscopy.Transurethral incision of ureterocele was undertaken for 6 cases,and transurethral unroofing for 9.All the patients have been followed up for 6～36 months with the hydronephrosis abated.No vesicoureter al reflux has been noted. Conclusions Transurethral inte rvention of ureterocele is simple and effective rendering minimal trauma to the patients.Transurethral unroofing is an effective means to treat ureterocele.

Objective To make the surgical therapy of urethral stricture and occlusion more effective. Methods 154 patients treated in our hospital were included in this retrospective study,of these cases,40 cases were in anterior urethra and 114 in posterior part.Based on etiology,106 cases were from trauma,15 from infection and 33 from idiopathic causes.Open surgery was performed on 34 cases and endoscopic therapy on 120 cases. Results All of the anterior urethral cases were treated successfully,among them,18 cases were with open surgery and 22 with endoscopic surgery.Normal urination was achieved on the follow-up from 6 months to 12 months.Within posterior urethral stricture and occlusion situation,open surgery was in 16 cases with 10 cases of normal urination and endoscopic surgery in 98 cases with 92 cases of normal urination.6 cases with open surgery and 5 cases with endoscopy resulted in postoperative dysuria or anuria.Urethral stricture and occlusion were shown in all these unsuccessful operation according to our urethrogram. Conclusions Good result can be achieved by both open and endoscopic surgery in anterior urethral stricture.In case of posterior urethral condition,endoscopic procedure is the best choice.

Objective To investigate the clinical characteristics,diagnosis and therapeutic prognosis of Pneumocystis pneumonia(PCP)in patients with acquired immunodeficiency syndrome (AIDS).Methods AIDS patients with PCP were searched through computer medical record information system,clinical data were analyzed retrospectively,patients were divided into respiratory failure group (n= 1 1 )and non-respiratory failure group (n= 1 2 ),partial pressure of oxygen in arterial blood(PaO2 ),degree of blood oxygen saturation(SaO2 ),CD4+T lymphocyte,and lactate dehydrogenase(LDH) between two groups were compared. Results 23 patients generally had the symptoms of weight loss,oral leukoplakia, shortness of breath,dyspnea,fever,cough,and expectoration. PaO2 value in 23 patients was (78.65±30.85)mmHg,partial pressure of carbon dioxide(PaCO2)was (24.42±5.60)mmHg,pH value was(7.43±0.79),SaO2 was (91.16±9.55)% ;SaO2 and PaO2 in respiratory failure group was lower than non-respiratory failure group,the difference was significant (both P<0.05).Lung computed tomography (CT)scans showed bilateral pulmonary ground-glass-like change. 21 patients used compound sulfamethoxazole tablets,1 patient used compound sulfamethoxazole tablets plus clindamycin,1 patient used only clindamycin,17 patients used glucocorticoid in addition to compound sulfamethoxazole;after treatment,20 patients improved,2 died,and 1 gave up treatment.Conclusion Subacute progressive dyspnea,fever,dry cough,and lung ground-glass-like shadow are common symptoms of PCP in AIDS patients,compound sulfamethoxazole or compound sulfamethoxazole with clindamycin can be used for treatment,glucocorticoid can obviously alleviate the symptoms of patients.

Objective To evaluate the efficacy of transversus abdominis plane (TAP) block for postoperative analgesia in the pediatric patients undergoing operation on the inguinal region.Methods Sixty-four pediatric patients of both sexes, aged 1-3 yr, weighing 8.5-23.6 kg, of American Society of Anesthesiologists physical status Ⅰ , undergoing elective unilateral high ligation of the hernia sac or high ligation of the processus vaginalis, were equally randomized into either intravenous analgesia group (group VA) or TAP block group (group TAP).In group TAP, after induction of anesthesia, the pediatric patients received ultrasound-guided TAP block with 0.2％ ropivacaine 1 ml/kg injected locally.After the laryngeal mask airway was inserted, the pediatric patients were mechanically ventilated, and then inhaled 2％-3％ sevoflurane for maintenance of anesthesia.In group VA, postoperative analgesia was performed with fentanyl 0.35 μg · kg-1 · h-1 until 24 h after operation.The level of pain was rated using the FLACC pain scale.When FLACC score＞5, fentanyl 0.25 μg/kg was injected intravenously as rescue analgesic.The occurrence of TAP block-related adverse events, time for removal of laryngeal mask airway, and occurrence of fentanyl-related nausea and vomiting, respiratory depression, and emergence agitation were recorded.Results No TAP block-related adverse events were observed in group TAP, and no respiratory depression was found in the two groups.Compared with group VA, the time for removal of laryngeal mask airway was significantly shortened, and the requirement for rescue analgesics and incidence of vomiting and emergence agitation were decreased in group TAP (P＜ 0.05).Conclusion TAP block with 0.2％ ropivacaine 1 ml/kg provides good efficacy for postoperative analgesia with good safety in the pediatric patients undergoing operation on the inguinal region.
