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.

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.

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.

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.

Objective To evaluate enteral nutrition treatment on nutritional status of patients with esophageal cancer during radiotherapy in Chinese population. Methods We searched domestic and foreign relevant databases (PubMed, Medline, Cochrane Library, Wanfang Data, Chinese Journal Database, VMIS) by key words (esophageal cancer, chemoradiotherapy, enteral nutrition) , meeting the conditions of the clinical randomized controlled trials, and evaluated the quality of each document. We used meta-analysis method to analysis the published literatures about clinical randomized controlled trials, which were enteral nutrition treatment on nutritional status of patients with esophageal cancer during radiotherapy in Chinese population.RevMan5.1 statistical analysis software were used. Results Seven separate clinical randomized controlled trials including 503 cases were included into the meta-analysis. The following five indexes of nutritional status in enteral nutrition treatment (ENT) group were superior to routine treatment (RT) group (P<0.05): body weight, Body Mass Index (BMI), hemoglobin, serum albumin, serum prealbumin. The MD Values and 95％CI (confidence interval) were 5.54 (3.61-7.46), 2.20 (2.02-2.39), 12.46 (5.86-19.05), 4.04 (2.48-5.61), 49.53 (20.93-78.13) .The funnel plot showed no significant publication bias in each indexes. Conclusion Enteral nutrition treatment can improve the nutritional status of patients with esophageal cancer during radiotherapy compare only with routine treatment.

Objective:To investigate the efficiency and pharmacoeconomics of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) for mobilization of peripheral blood stem cells (PBSCM) in patients with multiple myeloma (MM).Methods:The data of 91 patients with newly treated MM who were hospitalized in the First Hospital of Jilin University and Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from January 2015 to October 2017 were retrospectively analyzed. According to the patient's wishes, a high-dose chemotherapy combined with subcutaneous injection of PEG-rhG-CSF or recombinant human granulocyte colony-stimulating factor (rhG-CSF) was used for stem cell mobilization in 42 and 49 patients, respectively. The number of mononuclear cells (MNC) and CD34 + cells collected after mobilization, the maximum absolute neutrophil count (mANC), the cost of mobilization, and the engraftment time of white blood cells and platelets after transplantation were compared between the two groups. Results:The median number of MNC collected after mobilization in the PEG-rhG-CSF group and rhG-CSF group were 5.86×10 8/kg [(1.08-24.54)×10 8/kg] and 6.61×10 8/kg [(0.83-33.80)×10 8/kg], and the difference was not statistically significant ( U = 883.00, P = 0.245); while the median number of CD34 + cells collected after mobilization in the PEG-rhG-CSF group was higher than that in the rhG-CSF group [5.56×10 6/kg (0.94-19.90)×10 6/kg and 4.82×10 6/kg (1.12-14.61)×10 6/kg], and the difference was statistically significant ( U = 732.00, P = 0.038). The median number of mANC during mobilization in the PEG-rhG-CSF group was lower than that in the rhG-CSF group [20.50×10 9/L (7.26-61.30)×10 9/L and 32.08×10 9/L (6.92-69.99)×10 9/L], and the difference was statistically significant ( U = 490.00, P = 0.001). After autologous stem cell transplantation (ASCT), the time-to-recovery of white blood cell count (WBC) to 1.0×10 9/L in the PEG-rhG-CSF group was shorter than that in the rhG-CSF group [(11.59±1.98) d vs. (12.93±2.83) d], and the difference was statistically significant ( t = -2.395, P = 0.019), and the time-to-recovery of platelet count (Plt) to 20.0×10 9/L in the PEG-rhG-CSF group was also shorter than that in the rhG-CSF group [(12.86±2.62) d vs. (14.80±5.47) d], but the difference was not statistically significant ( t = -1.749, P = 0.085). The total mobilization cost of the PEG-rhG-CSF group was not statistically different from that of the rhG-CSF group [(21 405.47±7 365.98) yuan vs. (22 976.83±10 264.34) yuan, t = -0.721, P = 0.474]. Conclusions:PEG-rhG-CSF combined with high-dose chemotherapy is an effective option for PBSCM in MM patients, and its mobilization cost is equivalent to rhG-CSF. Therefore, PEG-rhG-CSF may be a better choice for PBSCM in MM patients.
