AIM: To evaluate the efficacy and safety of two different surgical techniques on congenital cataract on children.METHODS: Twenty-two children (1-3 years old) with congenital cataract were randomly divided into two groups (group A and group B). With group A (10 patients, 20 eyes), we applied 23-gauge (23G) trans corneal limbus vitrectomy system to complete lens cortex gettering, posterior capsulotomy and anterior vitrectomy；With group B (12 patients, 24 eyes), we used the phacoemulsification I/A to complete lens cortex gettering, and performed anterior vitrectomy with anterior vitreous cutting instrument. After that, the differences in intraoperative and postoperative complications between two groups were compared. RESULTS：In group A, the width of corneal limbal incision was 0.6mm, the incision was self-sealing, and the anterior chamber was stable and iris did not prolapse during the surgery. In group B, the width of corneal limbal incision was 3mm, anterior chamber was unstable and intraoperative iris prolapse occurred in 14 eyes (58%). And the incision need to be stitched up after surgery. In the postoperative follow-up of 6-24 months (an average of 14 months), we found that corneal neovascularization did not occur in group A, while in group B, corneal neovascularization occurred in four eyes (17%); Other complications, such as posterior capsular opacification，retinal detachment, glaucoma, hypotony or endophthalmitis did not occur in either group.CONCLUSION: The 23G trans corneal limbus vitrectomy system used in pediatric cataract surgery is safer and more effective than phacoemulsification I/A. It is promising in treatment of congenital cataract on children.

OBJECTIVETo explore the clinical effect of Agkistrodon antithrombogenase (AAT) in the treatment of rheumatoid arthritis (RA) and its possible mechanism.

METHODSBesides the conventional non-steroid anti-inflammatory agents and disease-modifying anti-rheumatic drug, patients were treated supplementally with intravenous injection of AAT. The intracutaneous test showed allergic to AAT patients were treated with Salvia injection and taken as control group. Changes of related clinical indexes in the two groups were observed.

RESULTSAfter 3 weeks treatment, condition of patients in both groups were improved clinically in joint swollen index, joint tenderness index, morning stiffness time, pain assessment (VAS) and health assessment questionnaire (HAQ) on daily life activity as well as ESR level (P < 0.05 or P < 0.01), with the VAS, HAQ and fibrinogen levels more significantly improved than those of control (P < 0.05 or P < 0.01), and the total effective rate higher in the AAT treated group than those in the control group (P < 0.05).

CONCLUSIONAAT has good effect on easing clinical symptoms of RA possibly through anti-inflammation and improving the microcirculation with less toxic and adverse reaction, so is worthy of recommendation.

This paper is aimed to study the effects of nitrogen form on the growth and quality of Chrysanthemums morifolium at the same nitrogen level. In order to provide references for nutrition regulation of Ch. morifolium in field production, pot experiments were carried out in the greenhouse at experimental station of Nanjing Agricultural University. Five proportions of ammonium and nitrate nitrogen were set up and a randomized block design was applied four times repeatedly. The results showed that the growth and quality of Ch. morifolium were significantly influenced by the nitrogen form. The content of chlorophyll and photosynthesis rate were the highest at the NH4(+) -N /NO3(-) -N ratio of 25:75; The activities of NR in different parts of Ch. -morifolium reached the highest at the NH4(+) - N/NO3(-) -N ratio of 0: 100. The contents of nitrate nitrogen in the root and leaves reached the highest at the NH4(+) -N/NO3(-) -N ratio of 50:50. The activities of GS, GOGAT and the content of amylum increased with the ratio of NO3(-) -N decreasing and reached it's maximum at the NH4 + -N/NO3 - -N ratio of 100: 0. The content of ammonium nitrogen were the highest at the NH4 + -N /NO3 --N ratio of 75: 25, while the content of soluble sugar reached the highest at the NH4(+)-N/NO3(-) -N ratio of 25: 75. The content of flavones, chlorogenic acid and 3,5-O-dicoffeoylqunic acid were 57.2 mg x g(-1), 0.673% and 1.838% respectively, reaching the maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75; The content of luteoloside increased with the ratio of NO3(-) -N increasing and reached it's maximum at the NH4(+) -N/NO3(-) -N ratio of 0: 100. The yield of Ch. morifolium reached it's maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75. Nitrogen form has some remarkable influence on the nitrogen metabolism, photosynthesis and growth, Nitrogen form conducive to the growth and quality of Ch. morifolium at the NH4(+) -N /NO3(-) -N ratio of 25: 75.

OBJECTIVETo study the effect of a low level of galacto-oligosaccharides (GOS) on intestinal bifidobacteria and lactobacilli, and fermentation characteristics in term infants by comparing with human milk and a standard infant formula without GOS.

METHODSA total of 371 term infants from four hospitals of China were enrolled. The infants started with breast feeding. After 1-2 weeks, some of the infants were changed to feeding with formula milk and then were randomly assigned to two formula-feeding groups: with or without GOS supplementation (2.4 g/L). Growth, stool characteristics, and side effects were recorded in a 3-month-follow-up. Faecal samples were collected for analysis of intestinal bacteria (culture technique), acetic acid (gas chromatography) and pH (indicator strip) at postnatal 3 months.

RESULTSCompared with the formula-feeding group without GOS, the contents of bifidobacteria, lactobacilli and acetic acid and stool frequency increased, and faecal pH decreased significantly in the GOS-formula-feeding and the human milk group. There were no significant differences between the GOS-formula-feeding and the human milk groups. Supplementation with GOS did not lead to an increase in the incidence of crying, regurgitation and vomiting.

CONCLUSIONSA supplementation of low levels of GOS in infant formula seemed to improve stool frequency, decrease faecal pH, and stimulate intestinal bifidobacteria and lactobacilli up to levels as found in breast-fed infants.

This research is to study the relationship between HPLC fingerprints of Moutan Cortex, Paeoniae Radix Rubra and Paeoniae Radix Alba and their activity on lipopolysaccharide-induced acute lung injury. HPLC fingerprints of each extract of Moutan Cortex,Paeoniae Radix Rubra and Paeoniae Radix Alba were established by an optimized HPLC-MS method. The activities of all samples against protein and tumor necrosis a factor were tested by the model of lipopolysaccharide-induced acute lung injury. The possible relationship between HPLC-MS fingerprints and the activitieswere deduced by the Partial least squares regression analysis method. Samples were analyzed by HPLC-MS/MS to identify the major peaks. The results showed that each sample had some effect on acute lung injury. Four components with a lager contribution rate of efficacy were calculated by the research of spectrum-effect relationship. Moutan Cortex exhibited good activity on acute lung injury, and gallic acid, paeoniflorin, galloylpaeoniflorin and paeonol were the main effective components.

Bcl-2 expression was relate d to lymph node metatasis and tumor polarization.The expression of P33ING1 was related to that of P53 in stomach cancer(P<0.05),while had no relation with that of Bcl-2.Conclusion:P33ING1 may play an importa nt role in the occurrance and development of stomach cancer.It's very important to detect the expression of P33ING1 and P53 simultaneously.

OBJECTIVETo investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).

METHODSA retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.

RESULTSCompared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.

CONCLUSIONCompared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.

[Objective] To investigate the prevalence, drug resistance and molecular characteristics of MRSA in hospital environment, so as to provide basis for prevention and control of nosocomial MRSA infection. [Methods]Specimens from Dec 2014 to May 2015 were collected from a tertiary hospital in Jing'an District of Shanghai and MRSA strains isolated from hospital environment and characterized by antimicrobial susceptibility testing and pulsed-field gel electrophoresis (PFGE). [Results]From 316 specimens were detected 46 MRSA strains with contamination rate being 14.6％ (46/316). And 22 (7.0％) were detected to be carriers of MRSA on the surfaces of ICU environment. MRSA had higher resistant rate to cefuroxime, levofloxacin, ciprofloxacin, Ampicillin/sulbactam, erythrocin, gentamycin than MSSA, and the difference was statistically significant (P<0.01). A total of 8 PFGE patterns were identified among the 14 MRSA isolates, which were mostly similar from one clone. [Conclusion] MRSA strains isolated from ICU in this hospital are multi-resistant to β-lactam antibiotics, quinolones and macrolides. There is clonal pollution in the environment. It is necessary to decrease the contamination rates between patients and environment, health care workers and environment, also it is worthwhile to increase the disinfection rate of environment.

OBJECTIVETo preliminary study the long term therapeutic effects of repeat the whole lung lavage (RWLL) in the treatment of silicosis.

METHODSA total of 60 patients with silicosis in the same stone mine were randomly and equally divided into repeat the whole lung Lavage (RWLL) group and whole lung Lavage (WLL) group based on silicosis staging, age and working age of dust exposure. Comparative analysis was performed to evaluate the long-term therapeutic efficacy and safety of RWLL. The cell count and SiO2 content were measured in twice right lung bronchoalveolar lavage fluid(BALF) of the RWLL group.

RESULTSFour years after treatment, the cough and asthma improvement rates of the RWLL group were 68.4% and 75.0% higher than those (52.4%and 57.9%) of the WLL group (P > 0.05). Six years after treatment, the asthma improvement rate (70.0%) of the RWLL group was significantly higher than that (36.8%) of the WLL group (P < 0.05). The RWLL group showed slight decrease in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1.0) after treatment (P > 0.05), while the WLL group showed significant decrease in FVC and FEV1.0 in the six years after treatment (P<0.05). Four and Six years after treatment, the RWLL group had higher no change rate and lower progression rate and significant progression rate than the WLL group in terms of chest X-ray (P>0.05). In the RWLL group,the first time the right lung BALF test showed a number of cells 6.71×10(7)∼2.14×10(9)/L, average 4.50×10(8)/L, pulmonary alveoli macrophages (PAM) ratio of 0.873∼0.980, average 0.954 and SiO2 content of 18∼104.7 mg, average 93.7 mg; the second test showed a number of cells 5.71×10(6)∼1.30×10(9)/L, average 9.12×10(7)/L; PAM ratio 0.710∼0.926, average 0.870 and SiO2 content of 6∼90.2 mg, average 46.2 mg. The RWLL group happened hemoptysis, chest pain one case in perioperative period, the incidence of 6.7%. The RWLL group complicated by left pneumothorax, pulmonary infection one case and the WLL group complicated by one case of lung cancer in a year of follow-up.

CONCLUSIONRWLL is reasonable and safe treatment which could help to further improve the long-term effects of WLL for silicosis.
