?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

Objective To evaluate the short-term efficacy of total hip arthroplasty combined with subcutaneous osteotomy in the treatment of CroweⅣ hip dysplasia (DDH).Methods From March 2012 to March 2015,14 patients (16 hips) underwent total hip arthroplasty with femoral distraction osteotomy S-ROM femoral stem prosthesis.And we observed its recent efficacy.Results All patients underwent S-ROM prosthesis.The patients underwent transverse osteotomy of the femoral trochanter.The osteotomy length was 2.0-3.5 cm.The average follow-up time was 19 months.And no complications such as dislocation,vascular nerve injury,deep vein thrombosis and infection were observed during the follow-up.The average Harris scores improved from 42.3 preoperatively to 90.4 postoperatively at 9 months after the operation.The average lengths of preoperative limb shortening and postoperative limb shortening were 6.4 cm and 4.3 cm respectively.The X-ray films showed no dislocation of acetabulum and femoral prosthesis.Bone healing was achieved at 6 months after osteotomy.Conclusion This method could be a good choice for Crowe Ⅳ developmental dysplasia.The short-term efficacy is satisfactory.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) plus Luohua Anshen oral liquid for patients with perimenopausal insomnia. Methods: A total of 66 participants who met the inclusion criteria were enrolled in the randomized controlled trial and allocated to a treatment group and a control group at a ratio of 1:1, with 33 cases in each group. Both groups were given Luohua Anshen oral liquid as a basic treatment. The treatment group was additionally given EA every other day, three times a week. Both groups were treated for four weeks and a four-week follow-up was conducted. The scores of Pittsburgh sleep quality index (PSQI), Kupperman index (KI) and traditional Chinese medicine sleep syndrome scale (TCMSSS) were recorded at pre- and post-treatment, and at the follow-up. Meanwhile, adverse effects were monitored and recorded. Results: After four-week treatment, the global scores of PSQI, KI and TCMSSS in both groups declined significantly (all P<0.05), and the decreases in the treatment group were more significant than those in the control group (allP<0.05). The global scores of PSQI, KI and TCMSSS in both groups at the follow-up visit were significantly different from the corresponding baseline (allP<0.05), while insignificantly different from those assessed at post-treatment (allP>0.05). The total effective rate was 93.9％ in the treatment group, significantly higher than 72.2％ in the control group (P<0.05). No significant adverse event was reported in this trial excepted one patient experienced slight dizziness in the first acupuncture treatment. Conclusion: EA plus Luohua Anshen oral liquid is safe for perimenopausal insomnia with satisfactory short- and long-term effectiveness, and it shows certain advantage compared with using Luohua Anshen oral liquid alone.

Photoautotrophic gametophyte cells of the brown macroalgae Laminaria japonica were cultivated in 500ml stirred tank photobioreactors under seven pulse feeding modes and one batch mode.It is the first time for the study of effects of the feeding time points and feeding quantity on macroalgal cell growth and nutrient consumption.Results showed that, with inoculum density of 50mg DCW/L, in modified APSW artificial seawater medium at 13℃, light intensity of 60μE/m2.s, light cycle of 16/8h L/D, aeration rate of 50ml/min, and agitation speed of 100r/min, feeding the culture with small nutrient quantity was beneficial for the synchronization between nitrate and phosphate absorption, and further for biomass production.Feeding when ambient nutrient was abundant or depleted was quite weak for large amount of biomass accumulation, which might be due to the slowing nutrient absorption, nutrient storage, or the divergence absorption between nitrate and phosphate.Feeding nutrient frequently with small quantity from mid-exponential growth of macroalgal cells, that is maintaining medium nutrient concentration between 1/3 and 1/2 of its initial concentration, was the most effective way for biomass production, with biomass increased by 12.270 times of for 51 days' cultivation.

Objective To discuss the anatomic features, clinical presentations, diagnosis,differentiations and treatments of congenital fourth branchial anomaly(CFBA). Methods The clinical data of 8 patients with CFBA were retrospectively analyzed. Results Of the 8 patients aging from 27 to 300 months(median age: 114 months), 4 male and 4 female; 3 untreated previously and 5 recurrent. All lesions, including 1 cyst, 3 sinus (with internal opening) and 4 fistula, located in the left necks. Three patients presented acute suppurative thyroiditis, 4 deep neck abscesses, and 1 neck lump. Preoperative examinations included barium esophagogram, direct laryngoscopy, ultrasonography, CT, MRI, and so on.The principles of managements were adequate drainage, infection control during acute period and radical surgery during quiescent period. Classic surgical approach consisted of complete excision of branchial lesions, dissection of recurrent laryngeal nerve and partial thyroidectomy. Selective neck dissection was applied in recurrent cases to extirpate branchial lesions, scarrings and inflammatory granuloma.Postoperatively, 1 case was with local incision infection which healed by wound care; 1 case was with temporary vocal cord paralysis which completely recovered 1 month after operation. No recurrence was found in all of 8 cases with follow-up of 13 to 42 months (median: 21 months). Conclusions CFBA relates closely anatomically with recurrent laryngeal nerve and thyroid grand. The barium esophagogram and direct laryngoscopy are the most useful diagnostic tools. CT and MRI are all beneficial to the diagnosis of CFBA.The treatment key to CFBA is the complete excision of lesion during a quiescent period after inflammatory control, together with the dissection of recurrent laryngeal nerve ,partial thyroidectomy and partial resection of lamina of thyroid cartilage (if necessary), which all can decrease the risk of complications and recurrence.For recurrent cases, selective neck dissection is a safe and effective surgical procedure.

Objective To investigate the distribution and antimicrobial resistance profiles of the imipenem-resistant Escherichia coli clinical isolates.Methods A total of 10428 Escherichia coli isolates were isolated from various specimens of patients at the first affiliated hospital of Wenzhou medical university from January 2011 to November 2015.The identification and antimicrobial susceptibility testing for Escherichia coli isolates were determined by VITEK Full Automated Microbiology Analyzer.Results Among 10428 Escherichia coli clinical isolates,including 62.69％ ESBLs-producing isolates,84(0.81％) were resistant to imipenem.The rates of imipenem resistance among Escherichia coli isolates from 2011 to 2015 were 0.14％ (2/1397 strains),0.47％ (9/1898strains),0.55％ (12/2170 strains),0.88％ (22/2489 strains) and 1.58％ (39/2474 strains).Among 84 imipenem-resistant isolates,50.00％ (42/84 strains) were ESBLs-producing isolates;the non-susceptibility rates of all imipenem-resistant isolates to cefazolin,ampicillin,ampicillin/sulbactam,ertapenem and ceftriaxone were more than 90.00％.However,the susceptibility rates of these isolates to nitrofurantion and amikacin were more than 50.00％ (50.00％ and 62.50％).The susceptibility rates of imipenem-resistant isolates to other types of antibiotics were less than 30.00％.Conclusion Imipenem has fine antimicrobial activity in vitro against Escherichia coli isolates.However,the prevalence of imipenem resistance among Escherichia coli clinical isolates is increasing year by year.

PURPOSE: T helper (Th) 17 cells play a critical role in the development of asthma, but the underlying mechanism of how interleukin (IL)-17 is regulated in allergic airway inflammation is poorly understood. In this study, we investigated the impact of Bcl11b on Th17 response in asthma. METHODS: Blood samples from patients with mild asthma (MA) and severe asthma (SA) were collected. Expression of Bcl11b, IL-4, IL-5, IL-13, IL-17A and transforming growth factor (TGF)-β1 were determined in CD4+ T cells and plasma by polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). Relative mRNA and protein levels of Bcl11b, IL-17A and genes involved in the TGF/Smad signaling pathway were examined by PCR, ELISA and western blot analysis in house dust mite (HDM)-challenged mice. Ectopic expression of Bcl11b in HDM-stimulated primary mouse splenocytes was achieved by nucleofection of Bcl11b expression plasmid. RESULTS: We found significantly decreased Bcl11b but increased IL-17A and TGF-β1 expression in patients with asthma and a strongly negative correlation between Bcl11b and these 2 cytokines in SA patients. Similar expression patterns of Bcl11b, IL-17A and TGF-β1 were also found in mice with HDM-induced allergic airway inflammation. We demonstrated further that Smad2/3 phosphorylation was increased in HDM-challenged mice and that ectopic expression of Bcl11b in HDM-stimulated primary mouse splenocytes reduced Smad2 phosphorylation and IL-17 expression. CONCLUSIONS: Our findings demonstrate a potential effect of Bc111b in controlling IL-17-mediated inflammation in asthma and suggest that Bc111b may be a useful therapeutic target for asthma.

Laminaria japonica gametophytic cells were cultivated in a photobioreactor under continuous shear stress (0-1000 r/min) in 60 hours and the following static cultivation within 23.5 days. The content of chlorophyll a reached the maximum value of 2.36 mg/L at the end of continuous shear stress when the agitation speed was 90 r/min, while the chlorophyll a (chl a) concentration decreased quickly and nitrogen and phosphorus were released under high shear force (270-1000 r/min). The cell injury ratio at 1000r/min was as 18 times as that of the control. During the recovery course, gametophytic cells showed themselves distinct recovery capability at all agitation speeds. Furthermore, the content of chl a is a more exact index as biomass than dry cells weight (DCW). Besides cell injury ratio, the liberation of phosphorus demonstrates the cells injury.
