OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.

METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.

RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).

CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

Objective To evaluate the running status of the water-improving projects in Gansu Province in order to further improve the supervising mechanism and raise the efficiency of defluoridation in drinking water.Methods The water-improving projects,either being normal,or intermittent,or discarded and the cause of abnormal running in 33 counties in Gansu Province were surveyed with unified standard method.Fluoride content in water was determined by F-ion selective electrode.Results 993 water improving projects covering 3389 fluorosis villages were surveyed,682 projects worked well[68.68%(682/993)]and had supplied water with normal fluoride contents to 2174 villages[64.15%(2174/3389)]and benefited 116.56 hundred thousand populations.And the rest 311[31.32%(311/993)]projects worked abnormally or supplied unqualified fluoride water.The main causes were the exceeded lasting life,insufficiency of water resources,high fluoride content in water and unqualified administration.Conclusions Most of the water-improving projects in Gansu Province are basically running normally,but about 1/3 of the projects do not function well,so the management of the projects must be improved and consummated.

OBJECTIVETo understand mental health status of the students and adults in the earthquake disaster areas, as to providing guidance on intervention for post-disaster psychological crisis.

METHODSThe Self-Reporting Questionnaire (SRQ-20), an appendix of The Ministry of Health of "emergency psychological crisis intervention guiding principles", was used among 1222 victims in Wenchuan earthquake, Sichuan province. This questionnaire survey was conducted in 729 students and 493 adult victims in a randomized method. Of the 734 questionnaires distributed and received in students, 729 were validly responded with efficiency rate of 99.32%; while for adults, 496 questionnaires distributed, 496 received, 493 were valid with efficiency rate of 99.39%.

RESULTS(1) In students victims, 65% responded that they did feel "uneasy, nervous or worried", followed by "easy to be scared", "feel unhappy", "easy fatigue" and "hard to make a decision". For adult victims, 80.5% replied that they felt "uneasy, nervous or worried", followed by "feel unhappy", "easy fatigue", "difficult sleeping", "easy to be scared". (2) The average of the SRQ score of student victims was 6.58 +/- 3.99, and 6.07 +/- 4.02 for males, 7.03 +/- 3.91 for females. The average of the SRQ score of student victims was 7.36 +/- 3.98, male 6.68 +/- 3.82, female 7.99 +/- 4.03. The significant differences (t(women) = 2.985, P < 0.01; t(total) = 3.332, P < 0.01) was observed in women and the total group of students and adults. (3) The SRQ positive screening rate of students group was 46.50%, the adult group was 52.33%, SRQ >or= 7 points and SRQ < 7 sub-group of students and adults of the total score there were significant differences (t(1) = 39.771, P < 0.01; t(2) = 31.961, P < 0.01). SRQ >or= 7 sub-group of students and adult women in between there was a significant difference (t = 23.641, P < 0.01), SRQ < 7 sub-group of students and adults in general and women there were significant differences (t(1) = 3.092, P < 0.01; t(2) = 2.911, P < 0.01). (4) SRQ scores with gender and age had had a positive relation (r(SRQ total-sex) = 0.118, P = 0.000; r(SRQ total-age) = 0.103, P = 0.000).

CONCLUSIONThe emotional suffering symptoms of students victims and adult victims should be "nervous, unhappy, vulnerable on issues such as fatigue", the adult group had a higher symptom rate than the group of students, the mental health was more serious than that of students, as influenced by some factors including age and gender. Students, being a special population group should be paid more attention to focusing a designated behavior intervention, as a planned manner of intervention.
