Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

AlM:To investigate the opportunity of the concomitant strabismus operation and the function in the treatment of strabismic amblyopia through analyzing the changes of binocular summation of pattern visual evoked potential ( P-VEP ) before and after the surgery of concomitant strabismus.
METHODS: ln this retrospective study we investigated 67 cases admitted in our hospital. All patients were less than 18a and the postoperation squint angle was less than ± 10△. Patients were divided into three groups according to the strabismus type, age, and amblyopia degree. P-VEP binocular summation response was recorded in all cases, to observe the changes of the binocular summation response of P-VEP before strabismus surgery and 1mo, 3mo after surgery. The P-VEP response of binocular /monocular ( B/M ) ratio was taken as an evaluation index.
RESULTS: B/M value of three groups all improved obviously 1mo after surgery, which the difference showed statistical significant (P<0. 01). 1) After 3mo surgery, B/M value in esotropia group was higher than that in exotropia group (P<0. 05). 2) After 3mo surgery, B/M value in≤6a group was higher than that in >12a group (P<0. 05). 3) After 1mo surgery, B/M value in severe amblyopia group was higher than that in mild group (P<0. 05). After 3mo surgery, B/M value in severe amblyopia group was higher than that in mild group significantly (P<0. 01).
CONCLUSlON: Concomitant strabismus surgery is suggested to be performed before 6 years old when the patients are difficult to improve the vision after amblyopia treatment, especially with the severe amblyopia and esotropia (accommodative esotropia must be excluded). The early operation is better to amblyopia treatment and binocular vision recovery.

Objective To investigate the influence of body temperature on the recovery from vecuronium-induced neuromuscular block.Methods Sixty-eight ASA I - II patients (39 male, 29 female) aged 19-69 yr undergoing elective surgery under general anesthesia were randomly divided into 2 groups: group I in which patients' body temperature was maintained at 37 ℃ using warming blanket; group II in which no measures were taken to maintain the patients' body temperature. The patients were premedicated with phenobarbital 2 mg?kg-1 and atropine 0.01 mg? kg-1 intramuscularly. Anesthesia was induced with fentanyl 5 ?g? kg -1, propofol 2 mg? kg-1 and vecuronium 0. 1 mg?kg-1 . After tracheal intubation anesthesia was maintained with inhalation of 0.8%-2.5% isoflurane and propofol infusion at a rate of 2-4 mg ? kg-1? h-1 .Neuromuscular block was monitored using accelograph (Biometer, Denmark) .The changes in TOF and T1 were monitored. T1was maintained at 10% by vecuronium infusion during operation. At the end of operation a bolus of vecuronium 80?g ? kg-1 was given intravenously and T1 was completely depressed. The time for T1 to returned to 5% ,25% and 90% and the time required for T1 to return from 25 % to 75 % were recorded. The total amount of vecuronium given was recorded. Temperature probe was placed in the esophagus ( core temperature) . The room temperature was also recorded. Results The body temperature was lower, the total dose of vecuronium was smaller and the vecuronium-induced neuromuscular block lasted longer in group II as compared with group I . There was close correlation between body temperature and vecuronium-induced neuromuscular block. Conclusions Lower core body temperature could prolong the vecuronium-induced neuromuscular block.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

Abstract: Objective To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

OBJECTIVETo study the selective dilatation effects of iptakalim (Ipt) on basilar and pulmonary arterioles, and endothelial cell function of these arterioles in hypoxic rats.
METHODSSD male rats were divided into 2 groups:control and hypoxic group fed in normobaric hypoxic environment (O2 7.8%, 8 h). Arteriole rings about (204 + 5) pm were isolated and the tension of hypoxic arterioles pre-contracted by 6 nmol/L endothelin-1 (ET-1) was observed with wire myograph system model (DMT 610 m). The relaxing response of hypoxic arterioles induced by different concentration of Ipt were detected and endothelial activity was also tested by acetylcholine.
RESULTS10(5) mol/L acetylcholine (ACh)-mediated vasodilatation of basilar and pulmonary arterioles was greatly reduced in the hypoxic group than those in control group (P < 0.05). Compared with normal group, a novel ATP-sensitive potassium channel opener Ipt at the concentration ranging from 10(-11) mol/L to 10(3) mol/L, caused stronger dose dependent vasodilatation on hypoxic pulmonary arterioles, and there was no significant difference between control and hypoxic basilar arterioles.
CONCLUSIONThe endothelial function of basilar and pulmonary arterioles was damaged under hypoxic state, and Ipt selectively increased dilatation effects on hypoxic pulmonary arterioles, but not on hypoxic basilar arterioles which could improve high altitude pulmonary edema pathological state and be the novel drug in the treatment of pulmonary hypertension.
