OBJECTIVETo study the relationship between serum testosterone levels and the plaque formation of the carotid artery in a population-based cohort of independently living healthy women above 60 years of age.

METHODSAnalysis of the healthy elders from a population-based cohort study in 9 communities of Beijing. Carotid intima-media thickness and atherosclerotic plaques were determined ultrasonographically. Serum testosterone levels were measured by immunoassay. The data were analyzed with ANOVA and logistic regression analysis.

RESULTSThere was an inverse correlation between testosterone and plaque formation in old females (P < 0.01), while no association was found in males. Female with testosterone levels in the lowest quartile (< 0.49 nmol/L) had more risk of plaque formation (OR = 3.805, P < 0.01) after adjusted with age and other traditional factors of atherosclerosis.

CONCLUSIONTestosterone concentrations are negatively associated with carotid artery atherosclerosis in old women in Beijing, experimental and prospective studies are needed to determine the possible therapeutic role of testosterone in atherosclerosis.

AIM: To investigate the ocular complication after radiation therapy for nasopharyngeal carcinoma(NPC).METHODS: The authors performed a previous study on keratopathy in 213 NPC patients who received first stage radiation and had at least 10 months of follow-up. These patients were categorized into three groups depending on NPC clinic stages. Rates and proportions of keratopathy occurring in these groups were compared and analyzed with Chi-square Test and Spearman rank correlation coefficient.RESULTS: Radiation keratopathy developed in 19 patients, about 8.9% (19/213). The latency value was 3 to 30days. The effect of NPC clinic stages and radiation did on the development of keratopathy was not statistically significant (P＞0.05).CONCLUSION: The NPC clinic stages and radiation doses plays few effects on the development of keratopathy. It may play a key role that corneal nerves damage induced ocular surface diseases. It can not be excluded that individuals have different sensitivities to radiation.

Objective To investigate the value of multi-b value DWI combined with PSA evaluation on the effect of endocrinotherapy for prostate cancer (PCa), and to study the correlation between the signal intensity(SI), apparent diffusion coefficient(ADC) with PSA.Methods Forty patients with PCa diagnosed by pathology or biopsy were tested for serum PSA levels before and after endocrine therapy.All patients underwent DWI at b-value of 300,800 and 1 000 s/mm2 by using a GE Signa HDx 3.0T MRI scanner.The serum PSA,the value of SI and ADC at different b values before and after endocrine therapy,and their correlation with PSA were observed and measured, respectively.Results (1)The serum PSA before and after endocrine therapy were (35.63±20.91) ng/mL and (5.98±3.84) ng/mL, respectively.The difference was statistically significant (P<0.05).(2)On the condition of different b values, ADC values were (1.06±0.06)×10-3 mm2/s, (0.83±0.04)×10-3 mm2/s, (0.73±0.03)×10-3 mm2/s, respectively before endocrine therapy, and (1.33±0.09)×10-3 mm2/s, (1.16±0.09)×10-3 mm2/s, (1.10±0.08)×10-3 mm2/s, respectively after endocrine therapy.There were significant difference between the ADC values before endocrine therapy and those after endocrine therapy (P<0.05).SI were 809.09±79.06, 417.42±26.65 and 327.42±25.26 in 40 patients with Pca before the endocrine therapy, and 780.10±78.52,409.33±33.93 and 320.00±31.10 after endocrine therapy.The difference was not statistically significant (P>0.05).(3)Pearsoncorrelation analysis showed that ADC value was negatively correlated with serum PSA (r300=-0.58,P<0.01;r800=-0.60,P<0.01;r1 000=-0.66,P<0.01) before endocrine therapy.ADC value was also negatively correlated with serum PSA (r300=-0.55,P<0.01;r800=-0.52,P<0.01;r1 000=-0.61,P<0.01) after endocrine therapy.In addition,SI was negatively correlated with serum PSA (r300=-0.09,P<0.01;r800=-0.18,P<0.01;r1 000=-0.28,P<0.01) before the treatment, as well.Conclusion ADC value at different b values increased after endocrine therapy in Pca, and is negatively correlated with serum PSA.The correlation is the most significant at b value of 1 000 s/mm2.The combination of DWI and serum PSA could be used to monitor and evaluate the effect of endocrinotherapy for Pca, and better guide the clinical treatment of Pca.

Twin pregnancy with mosaic partial hydatidiform mole (PHM) and survival of two healthy fetuses following in vitro fertilization and embryos transfer (IVF-ET) is a rare situation and is considered a challenge for management. A 32-year-old Chinese woman conceived twin pregnancy following IVF-ET. At 22 weeks' gestation, an additional intrauterine echogenic mass with features of PHM were shown by successive ultrasound examinations. At 35 weeks' gestation, two live male infants and two placentas were delivered by caesarean section (CS). Histologic examination of the abnormal placenta confirmed mosaic PHM. Genetic study showed the abnormal placental mosaicism (expressed in molar-69XXY and normal vili-46XY), co-existing with a hypospadia new-born (46XY) in one amniotic sac. However, the other one was normal. Serial serum β-hCG levels showed a declining trend and serum β-human chorionic gonadotropin (hCG) were undetectable at 6 months after delivery. The case demonstrated that it is possible to prolonged gestation by PHM under close surveillance during the entire pregnancy.

Objective To explore the value of stable micro bubble test (SMT) for early diagnosis of hyaline membrane disease (HMD), and to provide early intervention for clinical diagnosis method of hyaline membrane disease in premature infants. Methods A total of 288 premature infants admitted to neonatal intensive care unit (NICU) of Ankang City Central Hospital from January 1st, 2013 to January 1st, 2016 were involved into the study. The primary gastric juice 1-2 mL was extracted for SMT test within 30 minutes after the birth. The number of the stable micro bubble with diameter<15μm was counted by low magnification. The clinical symptoms and X-ray results within 6 h after the birth were used as the gold standard of diagnosis of HMD. The premature infants were divided into the case group and control group. The general information was compared between two groups. The optimal critical stable micro bubble value was determined by the ROC curve. The number of micro bubbles <5/mm2, <10/mm2, <15/mm2 and <20/mm2 were used as the threshold, and the sensitivity, specificity, positive and negative predictive values were calculated for HMD diagnosis. Results Among the 288 cases of premature infants, 91 cases (31.6%) were diagnosed as HMD, 197 cases (68.4%) were diagnosed as non HMD. There were lower gestational age, lower birth weight and more proportion of male babies in the case group compared with those of control group (P<0.05). There were no significant differences in prenatal usage of hormones, premature rupture of membranes, the proportion of cesarean section and 5-min Apgar scores between two groups. The number of micro bubbles of 15/mm2 was the optimal threshold for diagnosis of HMD, and AUC was 0.80 (0.73-0.84). When the number of micro bubbles of 5/mm2 was used for the diagnosis, 38 cases were in line with the diagnosed as HMD. When the number of micro bubbles of 10-15/mm2 was used for the diagnosis, 16 cases were in line with diagnosed as HMD. The number of micro bubbles of<15/mm2 was used as boundary value of HMD. The sensitivity, specificity, positive predictive value, negative predictive value and Youden index for SMT prediction and early diagnosis of HMD were 89.0%, 91.4%, 82.7%, 94.7%and 80.4%, which can be used as predictive indicators of HMD. Conclusion SMT test is simple, rapid, economic, high sensitivity and good specificity, which can effectively predict and early diagnose HMD, and have high clinical value.

AIM: To investigate the curative effect of phacoemulsification and intraocular lens ( IOL ) implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-closure glaucoma ( PACG) . · METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure ( IOP) was 33. 22 ± 3. 17mmHg; the average depth of anterior chamber was 2. 07 ± 0. 15mm;the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle. · RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15. 11 ± 3. 67mmHg,the chamber depth was 3. 11±0. 08mm;those of the Group B were 17. 24 ± 1. 67mmHg, 2. 76 ± 0. 15mm respectively; the differences had statistical significance (P<0. 05). Postoperatively, there were 28 eyes (70%) in Group A with fully open anterior chamber angle, and 18 eyes (45%) in Group B (P<0. 05). · CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.
