Ureaplasma urealyticum(UU)is one of the most common pathogen in childbearing age women.The proportion of neonate especially premature baby infected with UU is increasing yearly.UU infaction is related with premature labour,low birth weight,bronchopulmonary dysplasia,chronic lung disease,respiratory distress syndrome and other perinatal diseases by promoted the expression of inflammatory cytokines,increasing the inflammatory response and interfering inflammation clear.There still has controversial point to treat perinatal diseases caused by UU infection by erythromycin,azithromycin,pulmonary surfactant,steroid.

To observe the clinical efficacy of Artisan iris-clip intraocular lens ( lOL) implantation on cataract with a wide range of lens dislocation.
●METHODS: Twenty-four hospital patients (28 eyes) of cataract with lens subluxation by trauma (20 patients, 20 eyes) and Marfan's syndrome (4 patients, 8 eyes) during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris - clip lOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo.
●RESULTS: Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0. 1-0. 5 was in 20 eyes, 0. 5-1. 0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed.
●CONCLUSlON: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris - clip lOL implantation and obtain a better outcome.

Objective To observe the clinical curative effect of Gubenzhike granule on cough variant asthma (CVA), and explore its mechanism. Methods A total of 140 cases of CVA were randomly divided into two groups, 70 cases for each group. The treatment group took Gubenzhike granule orally, and the control group inhaled Budesonide Powder for Inhalation and Salbutamol Sulphate Aerosol, respectively for 8 weeks, with 8 weeks follow-up after treatment. The same nursing intervention was implemented in two groups. Cough symptom scores of the two groups were observed after treatment and at the end of follow-up, the number of eosnophils (EOS) and content of immunoglobulin E (IgE) in peripheral blood were also observed. Results The treatment group completed 67 cases and the control group completed 66 cases. After treatment, the cough symptom scores, EOS and IgE in two groups were significantly reduced (P<0.01, P<0.05), and the cough symptom score of treatment group decreased more significantly than that of control group (P<0.01). The total effective rate and recurrence rate were 91.04%and 9.84%in treatment group, and 83.33% and 30.91% in control group. The total effective rate of treatment group was better than the control group (P<0.01), and the recurrence rate was lower than the control group (P<0.01). Conclusion Gubenzhike granule showed significant effect and low recurrence rate on CVA. Good anti-inflammatory and antianaphylaxis effects may be one of its mechanisms.

Objective To transfect EGFP gene to porcine embryonic fibroblasts ( PEFs) of Tibetan miniature pigs by Lonza Nucleofector II machine and compare the tansfection efficiency between this method and the lipofection method. Method A plasmid carrying green fluorescent protein ( GFP) was transfected into PEFs of Tibetan miniature pigs via the Lonza Nucleofector II machine ( program U020) and by Lipofectamine 2000.Results 5 hours after nucleofection, green fluorescence was observed, indicating 80%transfecting efficiency in the nucleofection group, which is significantly higher than the lipofection group. Conclusion Nucleofector II machine can efficiently transfect PEFs, provides a reliable method for efficiently generate transgenic Tibetan minipigs.

Abstract: Objective　To investigate the molecular characteristics and drug resistance of non-O1/non-O139 Vibrio cholerae in Zhongshan City, and to provide laboratory basis for cholera prevention and control. Methods　The strains of non-O1/non-O139 Vibrio cholerae isolated from sporadic patients and aquatic products from 2015 to 2021 in Zhongshan city were collected. The identification and cluster analysis of the strains were analyzed by matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), the ctxA virulence gene of strains were detected by real-time fluorescence quantitative PCR, the cluster analysis of the strains was analyzed by pulsed-field gel electrophoresis (PFGE), and the drug resistance of the strains were analyzed by microbroth dilution method. Results　From 2015 to 2021, 33 strains of non-O1/non-O139 Vibrio cholerae were isolated from Zhongshan City, including 28 strains from sporadic patients and 5 strains from aquatic products. Through MALDI-TOF-MS identification, 33 strains of non-O1/non-O139 Vibrio cholera can be identified to the level of species, and the identification results were all Vibrio cholerae. Among 33 non-O1/non-O139 Vibrio cholerae strains, 1 strain carried the ctxA virulence gene. The drug-resistant strains accounted for 69.7% (23/33), and the multidrug resistant strains accounted for 18.2% (6/33). A total of 7 kinds of drug resistance spectrum were produced, including 3 kinds of multidrug resistant spectrum, and showed drug resistance to 8 antibiotics, among which the resistance rates to streptomycin, cefazolin and compound sulfamethoxazole were above 30%. The 33 strains of non-O1/non-O139 Vibrio cholerae were divided into 32 PFGE fingerprints with a similarity ranging from 61.7% to 100%. MALDI-TOF-MS cluster analysis divided 33 non-O1/non-O139 Vibrio cholerae strains into two clusters. Conclusions The results of molecular typing of non-O1/non-O139 Vibrio cholerae in Zhongshan City presented diversity, and no significant correlation was found between PFGE and MALDI-TOF-MS cluster analysis. The strains demonstrated various degrees of resistance to certain antibiotics, and there were multidrug-resistant and toxigenic strains. Therefore, it is necessary to alert to the harmfulness of non-O1/non-O139 Vibrio cholerae and enhance monitoring.

OBJECTIVETo determine the long-term clinical outcome and predictability of the maxillary sinus augmentation procedure.

METHODSSeventy-four patients underwent 100 sinus bone graft procedure and 206 implants were placed. The patients were followed up for 1-9 years, with an average of 3.46 +/- 1.65 years after implant placement.

RESULTSThe 5-year cumulative survival rate (CSR) of implants was 92.28%. Only 8 implants failed and no sinusitis occurred.

CONCLUSIONSSinus bone graft is an adjunctive procedure with a predictable outcome in patients with severely atrophied posterior maxilla.

Objective To explore the efficacy of non-T cell depletion haploidentical hematopoietic stem-cell transplantation for T lymphoblastic lymphoma (T-LL). Methods 3 T-LL patients achieving complete remission received haploidentical bone marrow stem cell transplantation with granulocyte-colony-stimulating factor (G-CSF) mobilized bone marrow grafts from related donor without T-cell depletion. Two of them received a myeloablative conditioning regimen consisting of high-doses of cyclophosphamide and cytarabine with total body irradiation, whereas the other was preconditioned with busulfan, cyclophosphamide and cytarabine. All patients received strengthened phophylaxis regimen including rabbit anti-thymocyte globulin against acute graft-versus-host disease. Results All patients had rapid hematopoietic engraftment with the median time for neutrophil and platelet recovery being 12 days and 13 days, respectively. They are still alive without relapse at a median follow-up of 24 months (range: 9-75 months). Conclusion Treatment related toxicity can be acceptable in non-T cell depletion haploidenfical hematopoietic stem-cell transplantation for T-LL and the patients may achieve long term survival.
