Help T cell 1/Help T cell 2 and some cytokines disequilibrium can give a suitable explanation for hypersensitivity and hypogammaglobulinemia in primary nephritic syndrome(PNS) patients. The disturbance of regulatory T cell(Treg cell) and Th17 cell can lead to correlated cytokines derangement, which explained the pathogenesis of PNS from another aspect. Refractory nephrotic syndrome can be effectively treated by rituximab followed the percentage of regulatory T cell increasing, which indicated that Treg may play an important role in pathogenesis of PNS.

Refractive surgery for myopia is a common operation and has been performed on millions of patients .Improved technology has increased the satisfaction of patients and physicians .Surgery must follow the basic requirements of medical ethics , to ensure the safety and best interests of the patients .The choice of procedure depends on individual patient indications and ocular exami -nations .Before the surgery , the opthalmologists must ensure that the patient understands the potential risk of the operation and has re -alistic expectations for the visual acuity postoperatively .

Objective To observe the therapeutic efficacy of auricular point sticking in preventing pain after perianal abscess surgery.Method Sixty patients going to receive radical perianal abscess surgery admitted by the First Affiliated Hospitalof Guangzhou University of Chinese Medicine between December of 2015 and February of 2016 were enrolled and randomized into an ordinary group and an auricular point sticking group. Pain was scored at different time points after the surgery and the use of analgesics was also recorded.Result There were significant inter-group differences in comparing the pain intensity from 6 h after the surgery till 7:30 on the next day of the surgery (P<0.05);the between-group differences in comparing the Visual Analogue Scale (VAS) scores from the 2nd day till the 7th day despite of the dressing change time were unstable(P>0.05,P<0.05); the differences in pain intensity at the dressing change were statistical significant (P<0.05).Conclusion Auricular point sticking can effectively treat mild-moderate pain in the early stage after perianal abscess surgery at non-dressing-change time, and it can also produce a satisfactory effect in preventing moderate-severe pain at dressing change after perianal abscess surgery.

Objective To investigate SCCmec types in clinical isolates of methicillin-resistant Staphylococcus epidermidis (MRSE) carrying psm-mec.Methods We collected 165 strains of Staphylococcus epidermidis identified by automated microbiological identification system and screened MRSE by PCR amplification of esp and mecA gene.Strains with psm-mec were identified by amplification of psm-mec,fudoh and p221 DNA fragment;mec,ccr and SCCmec typing was conducted by multiplex PCR assay.Results Among 138 strains of MRSE,29 strains were identified as MRSE with psm-mec,and the carrying rate was 17.58%.Results of mec and ccr typing by multiple PCR showed that MRSE with psm-mec carried Class A mec,but the ccr type had obvious diversity.Results of SCCmec typing showed that all strains with psm-mec belonged to type Ⅱ and/or Ⅲ SCCmec.Conclusion Clinical isolates of MRSE with psm-mec carry homologous type Ⅱ and/or Ⅲ SCCmec harboring Class A mec.

Objective To explore the establishment of peptide mapping database of Candida albicans ,laying the foundation for rapid diagnosis of Candida albicans infection .Methods 96 Candida albicans were collected clinically ,and its DNA was extracted . Polymerase chain reaction(PCR) was used to amplify the ITS1-5 .8S-ITS2 gene fragments and restriction endonucleases were a-dopted to identify them .Surface enhanced laser desorption ionization-time of flight-mass spectrometry(SELDI-TOF-MS) instrument was applied to detect the Candida albicans peptide mapping ,and Ciphergen ProteinChip software was used to collect data automati-cally .The established peptide mapping database was verified by confirmed Candida .Results According to restriction fragment length polymorphism analysis ,96 strains were confirmed as Candida albicans .15 peptide peaks were captured by SELDI-TOF-MS chips .Five peptide peaks of them with stable expression were screened out ,and the similarity analysis software was used to estab-lish peptide mapping database of Candida albicans .More than 95% of similarity was found between peptide mapping of Candida albicans and established database ,while less than 50% was found between peptide mapping of other Candida species and database . Conclusion The establishment of peptide mapping database of Candida albicans provides a theoretical basis for the rapid diagnosis of Candida albicans infection .

Objective To evaluate the diagnostic value of procalcitonin(PCT),C-reactive protein(CRP),prealbumin(PA)and white blood cell (WBC)count measurements in patients with severe pneumonia.Methods The serum samples of 34 patients with severe pneumonia,68 non-severe pneumonia patients and 40 healthy volunteers were collected.Serum concentrations of PCT,CRP, PA and WBC count of all samples were determined.Results The levels of PCT,CRP,PA and WBC in patients with severe pneu-monia were (24.07±34.77)ng/mL,(98.75 ±69.63)mg/L,(105.65 ±68.88)mg/L,(12.64±7.62)×109/L,which were signifi-cantly higher than those in non-severe pneumonia patients and healthy group(P <0.05).According to ROC analysis,the sensitivity, specificity and Youden index of PCT were 64.7%,77.9%,0.426.Conclusion The level of serum PCT could be used as good bio-marker for severe pneumonia.Detection of PCT,CRP and WBC together plays an important role in the diagnosis of severe pneumo-nia.

Objective To explore the effects of different extracts of modified Siwu Siteng Decoction (TFT-Ⅰ, TFT-Ⅱ) on rat models with hyperuricemia. Methods Rat model with hyperuricemia was induced by hypoxanthine and oxonic acid potassium salt. Seventy rats were randomly divided into 7 groups:normal group, model group, allopurinol group, TFT-Ⅰ high and low dose groups, TFT-Ⅱhigh and low dose groups. Each dose group was given lavage with related medicine, and blank group and model group were given lavage with distilled water for one week, respectively. Uric acid in serum (SUA) was measured through fully automatic biochemical analyzer, and xanthine oxidase (XOD) activity in serum and liver tissue was measured through colorimetric method. Results Compared with model group, TFT-Ⅰ and TFT-Ⅱ high dose groups significantly reduced the level of SUA, serum and liver XOD activity (P<0.05), with significant statistical difference between the two groups (P<0.05). TFT-Ⅰ and TFT-Ⅱ low dose groups had no significant effects on SUA, and XOD activity in serum and liver (P>0.05). Conclusion Alcohol soluble ingredients of astragalus membranaceus and Siwu decoction in modified Siwu Siteng Decoction can effectively reduce the level of blood uric acid.

Objective To establish protein fingerprints of common bacteria in clinics and to lay a foundation for rapid identification of bacteria.Methods Strains of Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa and Staphylococcus aureus were detected by surface enhanced laser desorption and ionization time-of-flight mass spectrometry (SELDI-TOF MS).Stable expression protein peaks were screened and the data was input into the self-constructed Fingerwave software for identification of target bacteria by protein fingerprint comparison.Two hundred and fifty-six clinical isolates,including E.coli,K.pneumoniae,P.aeruginosa and S.aureus were detected and the data was compared with constructed database to evaluate its diagnostic value.Results The protein fingerprints including four common bacteia was used to identify the target bacteria with identification rate of 93.1％ (54/58) for E.coli,87.2％ (75/86) for K.pneumoniae,96.2％ (60/63) for P.aeruginosa and 96.2％ (51/53) for S.aureus,respectively.Conclusion Common bacteria can be rapidly identified by using the protein fingerprint comparison,which provides a powerful tool for bacterial identification.
