?Dry eye is a common eye disease around the world, which has highly incidence. Although there are many treatment measures for dry eye, the clinical effect is not satisfactory. There is a close relationship between inflammation and dry eye, so the researchers pay more attention on anti -inflammatory therapy, such as fluorometholone. To explore the effect of anti -inflammatory medicine on dry eye, put forward the problems and shortcomings as well, lay the foundation for further study, and provide a strong theoretical basis for the clinical use of anti-inflammatory drugs in the treatment of dry eye, the author summarizes the clinical and experimental research progress of fluorometholone on dry eye in China and abroad.

OBJECTIVETo study the major social-psychological factors contributing to male juvenile delinquency.

METHODSOne hundred and thirty-seven cases of male juvenile delinquents (delinquent group) and 145 aged-matched male students (control group) were enrolled in this case-control study. A questionnaire survey was conducted using the Adolescent Self-Rating Life Events Check List, the Coping Style Questionnaire, the Family Environment Scale-Chinese version, and the Social Support Rating Scale.

RESULTSThe monovariate analysis showed that the total score and the scores of some factors of negative life events, the scores of immature coping styles and family conflicts, and the proportion of broken families in the delinquent group were significantly higher than those in the control group. In contrast, the scores of educational levels, study stress factor in the negative life events, mature coping styles, family environments and social supports were significantly lower in the delinquent group than those in the control group. The multivariate factors analysis showed that 7 variables were enrolled into the discriminatory equations, including negative life events (interpersonal relationship and healthy adaptation), self-condemn styles, family conflicts, subjective supports, objective supports, and utilization of social supports. The total accuracy of this equation was 92.2%.

CONCLUSIONSNegative life events in the interpersonal relationship and healthy adaptation, self-condemn styles, family conflicts, and weak social support system may be major social-psychological factors contributing to male juvenile delinquency.

Objective To evaluate the clinical impact of 18F-FDG PET/CT on patients with suspected cervical cancer recurrence. Methods Fifty-one cervical cancer patients, clinically suspected to have tumor recurrence during follow-up, underwent 18F-FDG PET/CT examination. 18 F-FDG PET/CT results were compared with those of conventional images, as referred to histopathology or clinical follow-up. Impacts of 18F-FDG PET/CT were evaluated based on documented changes of clinical management. Results In total, 43 patients were found to have positive lesions by 18F-FDG PET/CT, in which 40 were true recurrence,but 2 were pelvic abscess and 1 was radiation enterocolitis. Other 8 patients were found negative by 18F-FDG PET/CT and confirmed by pathology or follow-up. In patient-based analyses, the sensitivity, specificity, and accuracy of 18F-FDG PET/CT for the detection of tumor recurrence were 100% (40/40), 72. 73% (8/11),and 94.12% (48/51) respectively. In 7 patients, the clinical management was changed due to 18F-FDG PET/CT findings. Conclusion 18F-FDG PET/CT is an efficient tool for determining the recurrence of cervical cancer and instructing the clinical management.

OBJECTIVETo explore the clinical and epidemiological characteristics of serious cases of hand-foot-and-mouth disease (HFMD) infected by EV71, in order to provide scientific evidence for prevention and control of HFMD.

METHODSInformation was collected by questionaires through consulting medical cases. Data was input by Epidata, and analysed by software SAS 9.13.

RESULT201 severe cases were investigated. 84.65% of the cases were below 3 years old. The youngest one was 5 months and the oldest one was 8 years old. The ratio for male and female was 2.2: 1.85. 08% of the cases were distributed sporadically. 51.74% of them lived in rural, 29.36% of them lived in urban and 19.9% of them lived at the fringe area of rural and urban. 81.59% of the cases became serious between 1 and 4 days after infected. 100% cases had fever and 99.95% of them had a rash. 96.52% of them had nerve system symptoms. The main complications were virulent spinal encephalitis, pneumonia and breathing exhaustion. 98.01% of the patients were recovered or cured.

CONCLUSIONThe cases aged below 3 years old are high risk persons. Rural area and the fringe area of rural and urban are the key area for disease control. 1-4 days after onset is the key period to prevent complications.

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.

OBJECTIVETo explore the prevalence of chronic obstructive pulmonary disease (COPD) and its risk factors in rural area in the southern part of Hubei province and to provide evidence for prevention and treatment.

METHODSUsing uniform scheme, procedures and questionnaire, a multistage survey for 1883 people in rural area in southern part of Hubei province was performed, and physical examinations and lung function tests were conducted for every participant.

RESULTSIn this survey, 186 COPD cases were identified with a overall prevalence of 9.88%. The prevalence for male was 13.68% while in female it was 6.46%. The prevalence was higher in males than in females (chi2 = 27.48, P< 0.001) and higher with the increase of age (chi2 = 79.22, P<0.001). Factors associated with COPD were identified in one-way variance model as follows: sex, age, smoking, time for cooking, using biomass fuels for in-door cooking, family history, frequent cough before age 14, low body index and having house remodelling in the last five years. Results from multivariate logistic regression analysis showed that sex (OR= 1.3010), age (OR = 1.8506), smoking (OR= 3.0118), cooking time (OR= 1.7651), family history (OR = 1.5278), frequent cough before age 14 (OR = 2.8965) were risk factors.

CONCLUSIONThe prevalence of COPD in the southern part of Hubei province was high, suggesting that comprehensive intervention measures should be taken.

Stones in the seminal vesicles are extremely rare. We present a 62-year-old patient with a stone within a seminal vesicle cyst, who was cured by laparoscopic treatment. The operative time was 80 min, and the estimated blood loss was 90 mL. Scanning electron microscope examination of the stone showed a compact crystal image externally and sparse spherical crystal structure in kernel. Composition of the stone was calcium fluorophosphate on X-ray diffractometer. The follow-up time was 15 months with no recurrence of cyst or stone. To our knowledge, this case is the first to describe laparoscopic removal of a stone within a seminal vesicle cyst, and the first to describe calcium fluorophosphate as the composition of seminal vesicle stones.

A label-free method for sensitive and selective detection of thrombin ( Tb) was constructed based on rare earth ion mediated fluorescence switch of graphene quantum dots ( GQDs) . Rare earth ion ( Er3+) can assemble onto the surface of GQDs through the coordination interaction between Er3+ ions and the carboxylate groups located on the surface or edge of the GQDs, resulting in the aggregation of the GQDs and thereby decrease of the fluorescence of the GQDs. In the presence of Tb, the oxygen and nitrogen-donor atoms in Tb can coordinate with Er3+ ions and compete with the carboxylate groups on GQDs to coordinate Er3+ ions, thus the interaction between GQDs and Er3+ ions is reduced, which lead to the restoration of the GQDs fluorescence. In this study, the sensing mechanism was demonstrated by transmission electron microscopy, atomic force microscope, Fourier transform infrared spectroscopy, UV-Vis absorption and fluorescence spectroscopy. The limit of detection for Tb assay was as low as 0. 049 nmol/L. Moreover, this assay was successfully applied to the selective determination of Tb in real samples.
