Objective To explore the distribution of age,reasons for treatment,risk factors,and causes of vulvovaginitis in prepubertal girls.Methods A total of 4 214 prepubertal girls with vulvovaginitis who were admitted to the Girl's Sub-department,Zhongshan Boai Hospital from January 2010 to June 2013 was reviewed retrospectively.All clinical data were from medical records with files.Results Atotalof1 587 patients (37.7％) was0to1 years old,954 (22.6％) ＞ 1 to3 years old,1 289 (30.6％) ＞ 3 to 7 years old,and 384 (9.1％) ＞ 7 years old.Many risk factors were associated with vaginitis,including poor hygiene (2 924 girls; 69.4％),allergies and exposure to allergens (875 girls; 20.8％).Most common reason for treatment was a referral from physical examination accounting for 919 girls (21.8％),followed by vaginal secretions 812 girls (19.3％).The causes of vulvovaginitis of all patients were evaluated,1 771 of which (42.0％) were nonspecific vulvovaginitis,1 309 (31.1％) labial adhesions,375 (8.9％) bacterial vulvovaginitis,266 (6.3％) allergic vulvovaginitis,and 266 (6.3％) affective leg rubbing action.Conclusions Prepubertal vulvovaginitis occurred mainly in infancy and preschool.Floating population was common.They were caused by many risk factors including poor hygiene,allergies,poor urination habits,etc.The most common causes of vulvovaginitis were nonspecific vulvovaginitis and labia adhesion,yet allergies and affective leg rubbing action were the more common causes of recurrent vulvovaginitis.We propose that focusing on girls' reproductive health,timely treating allergic and crossing rub legs and other diseases would help reduce the prevalence of vulvovaginitis in the prepubertal girls.

OBJECTIVE: To explore the efficacy of individualized subcutaneous immunotherapy (SCIT) in allergic rhinitis(AR) maintain phase. METHOD: Compare nasal symptom scores (VAS) and special disease scale--nasal conjunctivitis quality of life questionnaire(RQLQ) score after 3 years treatment to evaluate the therapeutic effect of each group and the level of improving patients quality of life. Take patients' blood to detect the serum level of IL-10 by enzyme linked immunosorbent test (enzyme linked immunosorbent assay). RESULT: After 3 years treatment, there was no difference of VAS between the conventional SCIT group and the individualized SCIT group. ELISA results showed that the level of IL-10 was significantly higher in the drug symptomatic treatment group than that in the healthy group, the levels of IL-10 were significantly lower in the conventional SCIT group and the individualized SCIT group than that in the healthy group, but there was no difference between the conventional SCIT and the individualized SCIT group. CONCLUSION After 3 years treatment, there was no difference between conventional and individualized SCIT groups. But the efficacy of the conventional and individualized SCIT groups were significantly better than that in the drug symptomatic treatment group.

OBJECTIVEA novel bHLH-like gene, designated SmbHLH1, was isolated from Salvia miltiorrhiza, in order to identify a bHLH gene in related to danshinone biosysnthesis.

METHODSmbHLH1 was isolated by RT-PCR,and Semi-quantitative RT-PCR was used to detect the gene expression level.

RESULTThe full length of SmbHLH1 cDNA has an open reading frame of 999 bp. The deduced amino acid sequence of SmbHLH1 has 332 amino acid residues which forms a 36 kDa polypeptide with a calculated pI of 5.4. SmbHLH1 gene was expressed at high level in root, but low level in stem, leaf and flower of S. miltiorrhiza. The transcripts of SmbHLH1 was suppressed when the plants were treated with exogenous MeJA, Yeast + Ag+. The transcripts of SmbHLH1 constitutively accumulated in response to exogenous ABA and low concentration of salicylic acid.

CONCLUSIONSmbHLH is a new member of the S. miltiorrhiza bHLH family, and its possible roles in brassinosteriods signaling responses.

This study was aimed to construct a prokaryotic expressing vector of Hap gene from Nontypeable Haemophilus influenzae, and express and identify the fusion proteins of Hap-His in E. coli. The gene encoding protein Hap was amplified from Nontypeable Haemophilus influenzae ATCC49247 chromosomal DNA by PCR, then it was cloned into prokaryotic expression plasmid pET-32a (+). The recombinant plasmid pET-32a(+)-Hap was transformed into E. coli BL21 and expression was induced by Isopropy-beta-D-thiogalatoside(IPTG). The Hap-His fusion protein expressed so was analyzed by SDS-PAGE and Western-blot. The results showed that the recombinant expressive plasmid pET-32a (+)-Hap was constructed successfully, and the recombinant plasmid expressed Hap-His fusion protein with relative molecule mass 176 000 and mainly existed in inclusion body. This fusion protein could combine with anti-His monoclonal antibody specifically through Western blot analysis. Successful expression of Hap-His fusion protein in prokaryotic cell could lay a basis for further study of immunocompetence of Hap protein and development of NTHi vaccine.

OBJECTIVETo study pharmacokinetic parameters and absolute bioavailability for oral use of sinomenine tablet in beagle dogs.

METHODApplying to double cycle self crossover design, a single oral or intravenous dose of 10 mg x kg(-1) sinomenine was given to 10 beagle dogs. Drug concentrations in plasma were determined by HPLC. The pharmacokinetic parameters were calculated by 3P97 pharmacokinetic program.

RESULTThe concentration-time curves of oral administration fitted to one compartment model in the beagle dogs. The T(max), C(max), t1/2 and AUC(0-T) was (82.5 +/- 13.9) min, (0.15 +/- 0.027) mg x L(-1), (87.6 +/- 28.3) min and (28.43 +/- 3.48) mg x min x L(-1), respectively. The concentration -time curves of i.v. fitted to two compartment model in the beagle dogs. The t1/2beta and AUC(0-T) was (106.7 +/- 120.2) min and (93.32 +/- 82.08) mg x min x L(-1). The absolute bioavailability for oral use was (30.46 +/- 4.24)%.

CONCLUSIONThe absolute bioavailability of sinomenine is low, and the elimination of sinomenine tablet is fast.

OBJECTIVE: To evaluate symptoms and quality of life in children with allergic rhinitis, and to evaluate the correlations among the skin prick tests results, symptoms and quality of life. METHOD: Visual analog scale (VAS) was used to assess the symptoms severity, rhinoconjunctivitis quality of life questionnaire (RQLQ) was used to assess quality of life, the skin prick tests results were recorded, and statistics analysis was carried out among them. RESULT: (1) There were significant differences among the five aspects of RQLQ (F = 32.03, P < 0.01), nasal symptoms aspect was the most affected aspect of quality of life, moreover, there were significant differences among all the items of RQLQ (F = 7.35, P < 0.01), the scores of nasal blockage, sneezing and rhinorrhea were the highest, there were no significant differences among them. (2) VAS was significantly correlated with RQLQ, moreover, the scores of unable to get to sleep and embarrassed by symptoms were significantly correlated with rhinorrhea VAS scores (r = 0.230, P < 0.05; r = 0.325, P < 0.01), the score of wake up during the night was significantly correlated with nasal itching and sneezing VAS scores (r = 0.385, P < 0.01; r = 0.231, P < 0.05), the score of can't concentrate was significantly correlated with the scores of unable to get to sleep and wake up during the night (r = 0.316, P < 0.01; r = 0.525, P < 0.01), the score of irritable was significantly correlated with the scores of unable to get to sleep (r = 0.243, P < 0.05). (3) The results of the skin prick tests were related with VAS and RQLQ. CONCLUSION Nasal symptoms severity may significantly correlated with the quality of life. Rhinorrhea, nasal itching and sneezing may be the main factors affecting the quality of sleep, while the quality of sleep may affect non-hay-fever symptoms and emotions, rhinorrhea may be the main factor affecting embarrassed by symptoms. The allergen level was related with the symptoms severity and quality of life.

Madelung′s disease is a rare lipid metabolic disorder with unclear mechanism, characterized by the formation of diffuse uncapsulated lipomas in face, neck, shoulder and other body areas. This disease mainly affect middle-aged male, and is related to alcohol abuse. The treatment nowadays is only palliative surgery with a high recurrence rate, including lipectomy and liposuction. Both of them have advantages and disadvantages.

Objective To analyze solitary fibrous tumor (solitary fibrous tumor, SFT) ’s clinical manifestations, patholog-ical features, immunohistochemical phenotype, and follow-up, discuss the diagnosis, differential diagnosis and progno-sis. Methods Ten cases of SFT were analyzed by clinical data and follow-pathological characteristics study and im-munohistochemical staining of Vimentin, CD34, Bcl-2, CD99, SMA and β-catenin. Results There were 6 males and 4 females with ranging in age from 31 to 78 years (mean 53.2 years old). SFT in four cases originated from the visceral pleura, two cases from parietal pleura,one from the skin of the chest wall, one from the neck, one from the medi-astinum, one from subcutaneously. Microscopic examination of tumor tissue was mainly composed of spindle cells, dif-ferent levels of visible cells and cell-rich areas of sparse areas, tumor cells were short spindle or oval, mitotic due to the severity varies. During the visible rich collagen fibers, may be associated with hyaline degeneration or myxoid change. Immunohistochemistry revealed the tumor cells expessed Vimentin, CD34, Bcl-2, CD99 and β-catenin, SMA focal or weakly positive. Conclusion SFT may occur in various sites of the body. The clinicopathological features and immunohistochemical profile are helpful to identify SFT. Its biological behavior is consistent with its histological mor-phology and growth the way. If tumor could be removed completely, the patients may have a good prognosis;some have low-grade malignant or malignant behaviour, manifesting as local recurrence or metastasis. Patients need long-term follow-up.

A real time PCR assay for the detection of Vibrio parahaemolyticus in seafood samples was developed using a novel specific target and a competitive internal amplification control (IAC). The specificity of this assay was evaluated using 390 bacterial strains including V. parahaemolyticus, and other strains belonging to Vibrio and non-Vibrio species. The real time PCR assay unambiguously distinguished V. parahaemolyticus with a detection sensitivity of 4.8 fg per PCR with purified genomic DNA or 1 CFU per reaction by counting V. parahaemolyticus colonies. The assays of avoiding interference demonstrated that, even in the presence of 2.1 μg genomic DNA or 10(7) CFU background bacteria, V. parahaemolyticus could still be accurately detected. In addition, the IAC was used to indicate false-negative results, and lower than 94 copies of IAC per reaction had no influence on the detection limit. Ninety-six seafood samples were tested, of which 58 (60.4%) were positive, including 3 false negative results. Consequently, the real time PCR assay is effective for the rapid detection of V. parahaemotyticus contaminants in seafood.
