OBJECTIVETo observe the effect of Guilingji Capsule (GC) on the fertility, liver functions, and serum lactate dehydrogenase (LDH) of adult male SD rats exposed by 900 MHz cell phone.

METHODSTotally 18 adult male SD rats and 36 adult female rats in child-bearing period were selected and randomly divided into three groups according to weight equilibrium principle, i.e., the normal group, the radiated group, and the GC group, 6 males and 12 females in each group. Male rats in the normal group and all female rats were not radiated. Male rats in the radiated group and the GC group received radiation for 4 h per day, lasting for 18 successive days. Rats in the GC group received GC suspension at the daily dose of 0. 15 g/kg by gastrogavage at the same time. Equal volume of normal saline was administrated to other male rats. Then male rats were mated with corresponding female rats from the 14th radiation night to the 18th radiation night in the ratio of 1:2. Male rats were killed following on the next morning of ending the radiation. Female rats were normally fed and then killed before delivery. The pregnant outcomes of female rats in responding groups (the rates of pregnancy and the number of death fetus, birth weight, body length, and tail length) were observed and compared. Serum alanine aminotransferase (ALT), aspartate transferase (AST), AST/ALT, and LDH levels of the male rats were detected by colorimetry. Histological and morphological changes of liver were observed by HE staining.

RESULTSCompared with the normal group, the pregnancy rates of female rats decreased and the number of death fetus increased, the serum LDH level obviously increased in the radiated group (P < 0.05). Serum levels of ALT, AST, and AST/ALT were no significantly changed in the radiated group. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration appeared. Compared with the radiated group, the pregnancy rates increased, the number of death fetus dropped, and the serum level of LDH decreased in the GC group (P < 0.05). There was no obvious change in serum levels of ALT, AST, or AST/ALT. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration were significantly attenuated. The histomorphological structures recovered to normal basically in the GC group.

CONCLUSIONSThe pregnancy rates could be decreased, the number of death fetus increased, histomorphological structures abnormal, and serum LDH level increased by exposure toy GSM 900 MHz cell phone. GC could prevent and treat the aforesaid lesion. But there was no statistical difference in serum ALT or AST levels.

Objective To analyze the results of the Objective Structured Clinical Examination(OSCE) of medical interns in Department of Gynecology and Obstetrics,and to assess the role of OSCE in clinical teaching and practice. MethodsAtolal of 104 medical interns of five-year education program in 2002 and seven-year education program in 2003 in School of Medicine had taken part in OSCE of gynecology and obstetrics.The OSCE consisted of six stations: gynecologic examination,obstetric examination,oral test,interrogation of standardized-patients(SP),drawing partogram,and non-stress test(NST) explanation.After gathering the data of each station,the software of SPSS 11.0 was used to make statistical analysis. Results The median scores were as follows: 92.0 for gynecologic examination,91.0 for obstetric examination,83.5 for oral test,80.0 for interrogation of SP,80.0 for drawing partogram,and 70.0 for NST explanation.There was no significant impact of familiarity to OSCE on the results of the test.The results showed that medical interns did good job in basic performance,but lack of clinical practice skills in some complicated practice of gynecology and obstetrics.Conclusion The grading system and stations setup of OSCE in Department of Gynecology and Obstetrics in Shanghai Sixth People's Hospital show objectivity and equity.The OSCE can be widely applied in the after-department examination and even graduation examination.

Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.

Targeting induced local lesions in genomes (TILLING) is a reverse genetics method for functional genomics research.It is possible to screen for point mutations in the populations of EMS mutagenesis with highthroughput and lowcost. EcoTILLING a method based on TILLING ,was developed for detecting multiple types of polymorphisms in germplasm collections,such as single nucleotide polymorphism,small deletion and insertion etc.Rice is a very important food crop and a model plant for genome research also. There are complete genome sequence and a lot of other bioinformatics resources about it.So the markerassisted breeding is becoming more and more important in rice breeding. Some issues based on TILLING about identifying germplasm based on gene sequence,EMS mutagenesis breeding,developing functional marker in rice breeding in future were discussed.

Objective To understand the epidemiological characteristics of syphilis in Songjiang District of Shanghai from 2007 to 2017, and provide evidence for further improvement in the prevention and control measures. Methods Descriptive analysis was performed on the syphilis case data in Songjiang District from 2007 to 2017. Results In 2007-2017, a total of 8 546 cases of syphilis were reported in Songjiang District, with an average annual incidence of 48.23/100 000.The overall incidence showed a U-shaped upward trend, with the highest incidence in 2016 (68.17/100 000);the average annual incidence decreased by 6.13/100 000 from 2007 to 2010, whereas increased by 5.64/100 000 from 2011 to 2017.Syphilis was characterized as follows:1) The epidemic was dominated by the cases with local household registration, latent syphilis (51.84%), reported in June-September, aged 20-59 years (81.24%).The cases in the age group over 60 years showed a significant upward trend.2) In the local syphilis cases, there were more men than women, and the sex ratio was 1.3 : 1 (especially the sex ratio in the stage 1 and stage 2 syphilis was 1.73 : 1).In the foreign cases from other provinces, there were less men than women, and the sex ratio was 0.6 : 1. 3) In the primary syphilis cases, there were more men (35.50%) than women (20.98%), while more female cases in the latent syphilis and secondary syphilis cases.Local primary and secondary cases were mainly in the age group of 30 to 59 years (59.06%).The cases from other provinces were mainly 20 to 49 years old (85.24%). Conclusion The incidence of syphilis in Songjiang District is increasing.As primary syphilis are more likely to be male and young adults, we should strength the surveillance, establish standardized diagnosis and treatment of syphilis, advocate sexually transmitted diseases prevention and treatment and safe sexual behavior, and also promote active screening in women and the elderly for further control of syphilis.
