Objective To evaluate the perinatal outcome of three types of monochorionic diamniotic (MCDA) twins with selective intrauterine growth restriction (sIUGR).Methods From January 2005 to June 2012,clinical data of 42 pairs of MCDA twins (84 fetuses) with sIUGR and 71 pairs of normal MCDA twins (142 fetuses) in the same period were analyzed retrospectively in the First Affiliated Hospital of Sun Yat-Sen University.Fetuses with sIUGR were classified into three groups based on umbilical artery Doppler flow.There were 25 cases of type Ⅰ,11 cases of type Ⅱ and 6 cases of type Ⅲ.The perinatal outcome was compared between sIUGR and normal MCDA twins,and among the three types of sIUGR as well.Perinatal outcomes included gestational age at delivery,rate of intrauterine fetal death (IUFD),birth weight,intertwin discordance of birth weight,neonatal death and survival rate at 6 months.Results (1) The gestational age of sIUGR at delivery was significantly earlier than the control group [(34 ± 3),(36 ±2) weeks,respectively],and the rate of IUFD of both fetuses of sIUGR was significantly higher (4.8％,0,respectively).In the sIUGR group,the average birth weight of large or small twins[(2130 ±.350),(1520 ±400) g,respectively] was smaller than those in the control group [(2470 ± 500),(2340 ± 460) g,respectively].The difference was statistically significant (P ＜ 0.05,P ＜ 0.01,respectively).The intertwin discordance of birth weight in sIUGR group was significantly larger (27.6％) than the control group(4.0％,P＜0.01).(2) The gestational age at delivery in type Ⅱ and type Ⅲ [(34 ±5),(34 ±2) weeks,respectively] was significantly earlier than the control group (P ＜ 0.05).The rate of IUFD of both fetuses in type Ⅱ (18％) was significantly higher than in type Ⅰ (0) and the control group (0,P ＜ 0.05).In sIUGR group,the average birth weight of small twins in type Ⅰ,type Ⅱ and type Ⅲ was (1640 ±430),(1330 ±310) and (1500 ±380) g respectively,all of which were significantly smaller than that in the control group (P ＜ 0.05).The average birth weight of small twins in type Ⅱ was smaller than in type Ⅰ and the difference was statistically significant (P ＜ 0.05).In sIUGR group,the intertwin discordance of birth weight in type Ⅰ,type Ⅱ and type Ⅱ was 24.1％,34.6％,31.3％ respectively,all of which were significantly larger than that in the control group(4.0％,P ＜ 0.05).There were no statistically significant differences of the intertwin discordance of birth weight among the three types of sIUGR(P ＞0.05).Survival rate at 6 months in type Ⅱ (64％) was significantly lower than in type Ⅰ (92％) and the control group (91.5％,P＜0.01).Conclusions The perinatal outcome of MCDA twins with sIUGR is poor.The outcome is different among the three types of sIUGR,and type Ⅰ is the worst.Type Ⅱ is associated with a high risk of intrauterine fetal demise.It is important to monitor the intrauterine situation closely.

OBJECTIVEIn order to evaluate the safety and immunogenicity of group A + C meningococcal polysaccharide vaccine, a controlled field trial was performed among children at 6-24 months and 5-13 years old in Longsheng county, Guangxi Zhuang Autonomous Region.

METHODSMore than 600 children were selected in this trial. 428 children, aged 6-24 month-old and 5-13 year-old were involved in two experimental groups and were inoculated 100 microg of group A + C meningococcal polysaccharide vaccine. 103 children in positive control group were inoculated 50 microg of group A meningococcal polysaccharide vaccine while 94 children in negative control group were inoculated 30 microg of Typhoid Vi polysaccharide vaccine. Both systemic and local reactions were observed in each group at 6 h,24 h,48 h and 72 h after inoculation. Blood samples were collected in all children before and at 1 month after inoculation. Additionally, at least 50 blood samples were taken in each experimental group at 6 and 12 months after inoculation. Serum bactericidal antibody was tested by micro bactericidal test.

RESULTSBoth systemic and local reactions were mild in two experimental groups with only 3 children (0.7%) had > or = 37. 6 degrees C fever, 4 children (0.9%) appeared mild areola but all adverse reaction disappeared within 48 hours. In 5-13 year-old experimental group, the rates for four-fold increase of bactericidal antibody were 96.59% and 92.15% to group A and group C meningococcus respectively at 1 month after inoculation, and remained 90.91% and 90.08% at 12 months after inoculation.

CONCLUSIONGroup A + C meningococal polysaccharide vaccine was safe and having good immunogenicity among Chinese children.

OBJECTIVETo discuss the diagnosis and treatment of penile carcinoma in circumcised men.

METHODSWe reviewed 17 cases of penile carcinoma detected 1 month to 16 years after circumcision performed in our hospital from January, 1997 to December, 2004.

RESULTSOf the total number, 11 cases were diagnosed as penile carcinoma 1 - 12 months and the others 3 - 16 years after the circumcision. Sixteen of them were treated by partial penectomy, anti 1 first by extensive circumcision and later by partial and total penectomy successively after recurrence. Cloquet nodes biopsy showed 16 cases to be pathologically well-differentiated and I case moderately differentiated penile squamous carcinoma. One died of extensive metastasis, but the other 16 remained disease-free survivals.

CONCLUSIONCircumcised adult men, especially those over 40 years of age, are likely to develop penile carcinoma. Patients with inflammation, plaque or ulcer in the prepuce should be checked by pathological biopsy and followed up closely. For Stage-I penile squamous carcinoma, partial penectomy is shown to be an effective therapeutic option, and Cloquet's nodes biopsy is necessary for all patients.

BACKGROUNDThe blood vessels of a transplanted organ are the interface between donor and recipient. The endothelium in the blood vessels is thought to be the major target for graft rejection. Endothelial cells of a transplanted organ can be of recipient origin after transplantation. In this study, we tested whether endothelial chimerism correlated with the graft rejection and cold ischemia.

METHODSWe studied the biopsy samples from 34 renal transplants of female recipients who received the kidney from a male donor for the presence of endothelial cells of recipient origin. We examined the tissue sections of renal biopsy samples by fluorescence in situ hybridization (FISH) for the presence of endothelial cells containing two X chromosomes using a biotinylated Y chromosome probe and digoxigenin labelled X chromosome probe, and then analyzed the relationship between the endothelial cell chimerism and the rejection and cold ischemia.

RESULTSEndothelial chimerism was common and irrespective of rejections (P > 0.05). The cold ischemic time of chimerism group was longer than no chimerism group ((14.83 +/- 4.03) hours vs (11.27 +/- 3.87) hours, P < 0.05).

CONCLUSIONSThere is no correlation between the percentage of recipient endothelial cells in vascular endothelial cells and the type of graft rejection. The endothelium damaged by ischemic injury might be repaired by the endothelial cells from the recipient.

OBJECTIVETo diagnose achondroplasia prenatally by FGFR3 gene detection.

METHODSSeventy-eight fetuses affected by short-limb dysplasias were recruited. Umbilical blood sampling was employed to obtain fetal blood for karyotyping and FGFR3 gene detection. Genomic DNA was extracted, and the exon 10 of the FGFR3 gene was amplified. PCR amplicons were analyzed by DNA sequencing and restriction fragment length polymorphism with Bfm I. The FGFR3 exon 10 from the parents of the positive fetuses was screened by the same method.

RESULTSIn 78 fetuses affected with short-limb dysplasias, 8 cases had G1138A heterozygotic mutation and normal karyotype, and were diagnosed as achondroplasia. The other 70 fetuses had normal nucleotide at nucleotide 1138 in exon 10 of FGFR3, therefore were excluded from achondroplasia. Only one father in parents of the 8 achondroplasia fetuses also had the G1138A mutation.

CONCLUSIONAchondroplasia could be diagnosed prenatally in the fetuses affected with short-limb dysplasias by using PCR-RFLP and DNA sequencing of the exon 10 of the FGFR3 gene.

OBJECTIVE: To observe the clinical efficacy and safety of Jianpi Peiyuan acupoint thread embedding therapy on perimenopausal obesity (PMO). METHODS: Ninety-six patients of PMO were randomly divided into an observation group (48 cases) and a control group (48 cases). The control group received health education and lifestyle intervention. On the basis of the treatment in the control group, the observation group was treated with acupoint thread embedding at the main acupoints of Shangwan (CV 13), Zhongwan (CV 12), Xiawan (CV 10), Yinlingquan (SP 9) and Fenglong (ST 40), etc. as well as the supplementary acupoints in accordance with the syndrome differentiation, once every 2 weeks for 8 weeks (4 times in total). The indexes of obesity (body mass index [BMI], waist circumference, hip circumference and body mass), modified Kupperman score, insomnia severity index (ISI) score, self-rating anxiety scale (SAS) score, and self-rating depression scale (SDS) score of the two groups were observed before and after treatment, and the safety was evaluated. RESULTS: After treatment, BMI, waist circumference, hip circumference and body mass in the two groups were lower than before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). After treatment, Kupperman, ISI and SAS scores in the observation group were lower than before treatment (P<0.05), and ISI score in the control group was lower than before treatment (P<0.05). Kupperman, ISI and SAS scores in the observation group were lower than those in the control group (P<0.05). There was no significant difference in SDS between the two groups or within groups (P>0.05). No serious adverse reactions occurred during the experiment. CONCLUSION Jianpi Peiyuan acupoint thread embedding therapy can reduce the degree of obesity in PMO patients, and improve patients' the perimenopausal symptoms, insomnia and anxiety, with good safety.
