OBJECTIVETo investigate the correlation between Angle's class III patients' occlusion plane and anterior overbite by controlling the changes in occlusion plane during orthodontic treatment.

METHODSIn total, 90 Angle's class III adult orthodontic patients were selected as the experimental group, and 30 normal adults were selected as the control group. According to the overbite, the class III patients were divided into three groups, and 14 indicators were measured. ANOVA and multiple comparison analysis were used to analyze the difference between class III patients, and linear analysis was used to analyze the correlation between anterior overbite and anterior-posterior occlusion plane.

RESULTSIn class Ill patients, posterior occlusion plane and anterior overbite size were negatively correlated (r = -0.24, P < 0.05), whereas anterior occlusal plane and anterior overbite size were positive correlated (r = 0.23, P < 0.05).

CONCLUSIONThe shape of the occlusion plane varies in different anterior overbite patients. During orthodontic treatment in different overbite class III patients, the vertical height of the posterior teeth and the rotation of the occlusion plane should be controlled.

OBJECTIVE:To construct the evaluation index system for the effects of rational drug use policy in the military hos-pital. METHODS:Based on methods like literature analysis,expert consultation,modified Delphi method,analytic hierarchy pro-cess(AHP),the evaluation index system was constructed and the weight of indicators was calculated. The feasibility of the index system was verified by experimental evaluation. Through comparing drug use level between military patients and local insurance for medical care,the effects of rational drug use policy were evaluated in military hospital. RESULTS & CONCLUSIONS:The index system includes 3 first-level indexes as rationality,accessibility,economics,10 second-level indexes and 20 third-level indexes. The results of the experimental evaluation in 176 military hospitals show that the economic indexes scoring rate is lower than the reasonable indexes and the availability indexes,and the difference value are 3.12%and 4.06%;the first-level indexes average scor-ing rate of divisional hospital is higher than that of regimental hospital,and the difference value is 21.6%. The index system solves the problems of false data,incomplete evaluation,inadequate check,improves informatization level of evaluation,and realizes long-term dynamic monitoring and remote evaluation.

Objective To evaluate ketamine-induced cerebral protection in mice with traumatic brain injury (TBI) by magnetic resonance imaging (MRI).Methods Thirty-two pathogen-free healthy male C57BL/6 mice,aged 8 weeks,weighing 26-30 g,were divided into 4 groups using a random number table:control group (group C,n=7),ketanine group (group K,n=7),TBI group (n=9) and TBI plus ketamine group (group TBI+K,n =9).TBI was produced with a pneumatically driven controlled cortical impact device.Ketamine 150 mg/kg was intraperitoneally injected at l h after operation in TBI+K and K groups,while the equal volume of normal saline was given instead in TBI and C groups.Open field test was conducted at 24 h,72 h and 7 days after operation.The animals in TBI and TBI+K groups were scanned by T1-weighted MRI at 6,24 and 72 h after operation,the animals in C and K groups were scanned by MRI at 24 h after operation,and the development of cerebral edema was observed.Results MRI scan showed no cerebral edema in C and K groups,and different degrees of cerebral edema were found in TBI and TBI+K groups.Compared with group C,the locomotor distance was significantly shortened at 24 and 72 h after operation in group TBI (P＜0.05).Compared with group TBI,the size of cerebral edema was significantly decreased,and the locomotor distance was prolonged at 24 and 72 h after operation in group TBI+K (P＜0.05 or 0.01).Conclusion MRI method further clarifies that ketamine can produce cerebral protection to some extent in mice with TBI.

OBJECTIVETo explore the potential molecular mechanisms for Bushen Tiaojing Recipe (BTR) improving the endocrine function of ovarian granular cells by observing the effect of BTR containing serum on follicle stimulating hormone/cyclic adenosine monophosphate-protein kinase A (FSH/ cAMP-PKA) pathway in in vitro cultured human ovarian granular cells.

METHODSThe primary ovarian granular cells collected from in vitro fertilization-embryo transfer patients were cultured for 24 h. The human and rat serum containing different concentrations of BTR (low, medium, high dose), and their normal serums were co-incubated with ovarian granular cells for 48 h respectively, and then they were divided into the low, medium, high dose BTR groups and the control group. The levels of estradiol (E2), progesterone (P), and cyclic adenosine monophosphate (cAMP) in the culture medium were measured by radioimmunoassay. The protein expression of FSHR in ovarian granular cells was detected by Western Blot. The mRNA expression of follicle stimulating hormone receptor (FSHR) and P450 aromatase (P450arom) in ovarian granular cells were detected by Real-time PCR.

RESULTSIn human BTR containing serum groups: Compared with control group, the levels of E2 and cAMP in the culture medium were higher (both P < 0.05) in the medium and high dose BTR groups; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells increased (all P < 0.01), the mRNA expressions of P450arom in ovarian granular cells were higher (P < 0.05, P< 0.01) in the medium and high dose BTR groups. In rat BTR containing serum groups: Compared with the control group, the levels of E2 in the culture medium were higher (all P < 0.01), cAMP in the culture medium were higher (P < 0.05, P < 0.01) in the medium and high dose BTR group; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells were higher (all P < 0.01), the mRNA expression of P450arom in ovarian granular cells increased in the medium and high dose BTR groups (P < 0.05, P < 0.01).

CONCLUSIONBTR could possibly improve the endocrine function of ovarian granular cells by regulating main effector molecules FSHR, cAMP, P450arom, and E2 in FSH/cAMP-PKA pathway of ovarian granular cells.
