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.

?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.

China Biotechnology 2008;28(1):36-43
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.

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.

OBJECTIVETo discuss the indications, risks and benefits of endoscope-assisted transoral approach to excise the submandibular gland.
METHODSA retrospective review of a series of 12 patients treated by endoscope-assisted transoral submandibular gland excision was carried out. Of the 12 patients, 8 were chronic sialoadenitis (2 cases with sialolith), 3 were pleomorphic adenoma, and 1 was cyst of submandibular gland. Preoperatively, all patients were diagnosed as benign diseases by Ultrasonography, CT or MRI. Pathologic diagnosis of 8 cases were identified by fine needle aspiration cytology (FNAC) or fine needle aspiration biopsy (FNAB).
RESULTSTemporary lingual sensory paresis and temporary limitation of tongue movement were found in two patients. However, these signs soon resolved spontaneously within 1 - 3 months. There were no other complications. Postoperatively, mean satisfaction score with cosmetic results was 10. All patients were satisfied with the cosmetic results. No recurrences were found in patients with pleomorphic adenoma with a follow-up period ranged from 12 months to 48 months (median follow-up period: 36 months).
CONCLUSIONSEndoscope-assisted transoral excision of the submandibular gland is a feasible and safe approach for the benign diseases of the submandibular gland. The major advantages of this approach are no external scar and no injury to the marginal mandibular nerve.
