OBJECTIVETo observe the effect of Cuichan Zhunsheng Decoction (CZD) on the cervical ripening factors in late pregnancy.

METHODSNinety women with full-term pregnant ready for labor inducing were equally assigned to 3 groups. The treated group was orally treated with CZD, the control group was with pitocin by adding 1 U into 500 mL of 5% glucose for intravenous dripping in 6 h, and the placebo group was orally treated with simulator of CZD as placebo, with the medication lasted for 3 days. Changes of cervical length and width, and neck tube diameter were measured by vaginal B-ultrasonography to estimate the degree of cervical maturation referring to the clinical Bishop scale; meanwhile, changes in blood levels of prostaglandin E2alpha(PGE2alpha), interleukin-8 (IL-8) and endothelin-1 (ET-1) were measured.

RESULTSThe total effective rate on cervical ripening was 96.7% in the treated group, which was significantly superior to those in the control group (83.3%) and the placebo group (26.7%, P < 0.05). The blood levels of PGE2alpha, IL-8, and ET-1 after treatment in the treated group were significantly higher than those in the placebo group (P < 0.05), and levels of PGE2alpha and IL-8 were higher in the control group than in the placebo group (P < 0.05).

CONCLUSIONCZD can promote the cervical ripening through raising blood levels of PGE2alpha, IL-8 and ET-1, altering the structure of cervical tissue to reduce the cervical tension, which could increase the maturation of cervix, induce delivery sign, so as to elevate the vaginal delivery rate and reduce the percentage of caesarean birth.

OBJECTIVETo observe the efficacy of Modified Xiaoyao Decoction (MXD) combining clomipramine in treatment of depression.

METHODSOne hundred and five depression patients were randomly assigned to two groups. The treated group (53 patients), all were differentiated as Gan-qi stagnation syndrome type and treated with MXD combining clomipramine 25-50 mg/d. The control group (52 patients) treated with clomipramine 75-225 mg/d alone. The treatment lasted for 8 weeks in both groups. Scores of depression was assessed with Hamilton Depression Scale (HAMD) before treatment and at the 2nd, 4th, 8th week of the treatment, efficacy and adverse reactions were evaluated with Global Impression of Change (CGI) and Treatment Emergent Symptom Scale (TESS) respectively.

RESULTSAfter treatment the scores in both groups were significantly different from those before treatment (P < 0.01), but no significant difference was found between the two groups (P > 0.05). Main adverse reactions were dry mouth, constipation in the treated group, much less than those in the control group, which were mainly dry mouth, constipation, dizziness, insomnia, blurred vision and prolonged Q-T interval (P < 0.01).

CONCLUSIONMXD combining clomipramine has the efficacy on depression similar to clomipramine, but has less adverse reactions.

OBJECTIVETo evaluate effectiveness therapeutic regimens for obstructive sleep apnea hypopnea syndrome (OSAHS) children at an acceptable cost.

METHODThis study was performed at Yuying Children's Hospital of Wenzhou Medical University from Mar. 2008 to Dec. 2010. Prospective random number table method was used for the analysis; 60 children with mild OSAHS were divided into Mild OSAHS Montelukast Treatment (MM) group and Mild OSAHS Adenotonsillectomy Treatment (MAT) group. 32 children in MM group were treated with leukotriene receptor antagonists (LTRAs), while 28 children in MAT group were treated with adenotonsillectomy. Also, 58 children with moderate and severe OSAHS were divided into severe OSAHS Montelukast Treatment (SM) group and severe OSAHS Adenotonsillectomy Treatmen (SAT) group. Twenty-two children in SM group were treated with LTRAs, while 36 children in SAT group were treated with adenotonsillectomy. All selected children were evaluated by polysomnography (PSG) and Obstructive Sleep Apnea-18 (OSA-18) items before and after a six-month treatment. Both records were taken and analyzed, surgical complications and the reason for non-remission after operation were also analyzed. Two therapies were compared based on economic consideration and therapeutic effect. Result (1) PSG: A significant change of a significant change of Apnea Hypopnea Index (AHI) was observed in MM group after the treatment (before receiving the treatment 4.56 ± 1. 26, and after receiving the treatment 3. 48 ± 1. 52, t =3. 50, P <0. 05). But for oxygen desaturation Index (ODI) (MM group 2. 18 ± 2. 19, and MAT group 1. 80 ± 2. 34) and Lowest Oxygen satuation (LSaO2) (MM group 91. 66 ± 2. 34, and MAT group 92. 79 ± 2. 18), there was no significant difference in MM group and MAT group after the treatment (ODI, t =0. 65, and LSaO2 t = - 1. 93, P >0. 05). (2) OSA-18 scores: Significant differences were found in sleeping disorder (before 14. 81 ± 6. 28, and after 10. 56 ± 3. 57), the degree of familial stress (before 13. 56 ± 3. 54, and after 8. 97 ± 2. 96), and OSA-18 total scores (before 52. 66 ± 1. 11, and after 42. 56 6. 48) in MM group after the treatment (sleeping disorder Z - 3. 14, the degree of familial stress Z = -4. 50, and OSA-18 total scores Z= -4. 01, P <0. 05). (3) In addition to the cost of drugs, groups with surgical treatment had a larger economic burden than those with LTRAs treatment. (4) Treatment was totally effective for 28 children (88%) in MM group, and 28 children (100%) in MAT group. Meanwhile, treatment also achieved an obvious effect on 2 children (9%) in SM group, and in 35 children (97%) in SAT group. In MAT group, 3 children improved (11%). And in SAT group, 7 children improved (19%), but treatment was found to be ineffective in 1 case (3%). Among those effective and ineffective cases in groups with surgical treatment, there were 9 children with nasal diseases.

CONCLUSION(1) Surgical treatment is recommended as the first choice for children with moderate and severe OSAHS. And for those who also suffer from nasal diseases, treatment combining drugs with surgery is necessary. (2) LTRAs therapy has a good effect for mild OSAHS. Surgery is also recommended when drugs could not achieve any obvious improvement in clinical symptoms of children with mild OSAHS.

AIMTo elevate the encapsulation efficiency, decrease the burst release and improve the release of protein entrapped in poly (lactic-co-glycolic acid) (PLGA) microspheres. The bovine serum albumin (BSA) composite microspheres of alginate-chitosan-PLGA were prepared and the release characteristics of BSA from this composite microspheres were studied.

METHODSThe much smaller calcium alginate microcapsules were first prepared by a modified emulsification method in an isopropyl alcohol-washed way and coated with chitosan, then the alginate-chitosan microcapsules were further entrapped in PLGA to form the composite microspheres. The protein concentration was determined using a BCA protein assay kit. The release profiles were changed with various formulation factors.

RESULTSThe average diameter of the composite microcapsules was about 30 microm. Comparing with 60% to 70% of the conventional PLGA microspheres, the average encapsulation efficiency was more than 80%, and the burst releases in phosphate buffer solution of the composite microspheres decreased from 40% and 50% to 25% and further to 5% in saline solution.

CONCLUSIONThe novel composite microspheres were prepared, the drug encapsulation efficiency increased and the burst release decreased. The desired release profiles could be obtained by regulating the ratios of PLG and PLA in the composite microspheres.
