Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

Objective To investigate the effect of radical surgical excision of total cyst for hepatic cystic echinoccosis. Methods During six years,86 patients with hepatic cystic echinococcosis were treated by radical surgical excision of the total cyst.Hospital stay,abdominal drainage time,residual cavity drainage,accumulated liquid in residual cavity,residual cavity infection and recurrence were compared with that in 90 cases receiving internal capsule extirpation. Results Radical surgical excision of total cyst for hepatic cystic echinococcosis is safe and very effective,the average hospital stay was significant shorter(P＜0.001)and there was no significant complications such as billiay fistula,residual cavity infection,accumulated liquid of residual cavity and recurrence of hydatid cyst. Conclusion Radical surgical excision of total cyst is an ideal and new therapeutic method for the treatment of hepatic cystic eehinococcosis.

OBJECTIVE: To explore the value of estimating chronologic age based on the grades of mandibular third molar development. To evaluate whether mandibular third molar could be used as an indicator for estimating the age under or over 18 years. METHODS: The mineralization status of mandibular third molar of 1 845 individuals aged 10 - 30 was graded and marked based on Demirjian's classification of grades reformed by Orhan. Gender difference was examined by t-test. A cubic regression model was established to analyze the correlation between third molar and chronologic age. Each grade of age cumulative distribution diagram and ROC curve was respectively performed to evaluate the relationship between third molar and the age of 18. Using Bayes discriminant analysis, an equation was established for estimating the age of 18. RESULTS: The inner-rater reliability was 0.903. Statistical analysis showed a moderate correlation between age and grade. Significant differences of both genders were found only in grade D and H (P < 0.05). Males at the grades from 1 to D and females at the grades from 1 to C were under 18 years old, and both males and females at grade H were over 18 years old. The area under the ROC curve was 0.797 (P < 0.05). CONCLUSION Third molar development shows a high correlation with age, and combined with other indicators, it can be used to estimate the age of 18.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

Background Even though the change in wavefront aberrations with correction modality is well documented in the literature,little is known about the underlying mechanism.Complete understanding of the causes responsible for the wavefront change in the combined lens-eye system is important since it provides basic knowledge for further improving the technique to correct refractive error by correcting lenses.Objective The aim of this study was to investigate the influence of refractive correction lens on optical property of the eye by analyzing Zernike aberrations in myopic eyes with contact lens correction.Methods This study was approved by the Ethic Committee of Wenzhou Medical College.Written informed consent was obtained from each subject before entering this study.Zernike aberrations of 52 myopic eyes of 26 subjects with the spherical equivalent-1.75 to-8.50 D were measured using a Hartmann-Shock wavefront sensor.The human eye aberrations were examined at the uncorrected condition,rigid-gas-permeable contact lens (RGP-CL) corrected condition and soft contact lens (Soft-CL) corrected condition.The differences of wavefront aberrations and Zernike coefficients were compared by repeated measurement of single factor variance analysis,and correlation of the aberration changes between uncorrected condition and RGP-CL corrected condition or Sofi-CL corrected condition,between the right eyes and left eyes in different conditions were analyzed by Pearson linear correlation.Results Mean total root-mean-square (tRMS) was (0.71 ± 0.30)μm,(0.54±0.19)μm and (0.74±0.32)μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference (F =8.758,P＜0.001),and tRMS was significant declined under the RGP-CL corrected condition compared with uncorrected condition (t =2.746,P =0.008),and tRMS in RGP-CL corrected condition was significantly lower than that in Soft-CL corrected condition (t =3.428,P =0.001).The high RMS (hRMS) was (0.34±0.12) μm,(0.28 ±0.12) μm,(0.40±0.14) μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference among them (F =10.681,P＜0.001).An insignificant decrease of hRMS was seen in the RGP-CL corrected condition compared with uncorrected condition (t =1.987,P=0.053),but hRMS value was significant higher in the Soft-CL corrected condition than that in the uncorrected condition (t=2.101,P=0.041) and RGP-CL corrected condition (t=4.266,P＜0.001).Compared with uncorrected condition,the axis astigmatism (C5) and spherical aberration (C12) in the RGP-CL corrected condition and spherical aberration (C12) in the Soft-CL corrected condition were significantly reduced (P＜0.05),and the absolute values of trefoil (C6),vertical coma (C7) and tetrafoil (C10) in the RGP-CL corrected condition were lower than those of the uncorrected condition,but vertical coma (C7) absolute value in the Soft-CL corrected condition was increased (P＜0.05).A significantly positive correlation was seen in the spherical aberration (C12) between the RGP-CL corrected condition and uncorrected condition (r =0.763,P＜0.001),and less significant correlation was in the secondary astigmatism (C11) between the Soft-CL corrected condition and uncorrected condition(r=0.469,P＜0.001).Conclusions Different contact lens corrected conditions exert their effects on ocular wavefront structure due to its unique interaction with the eye.RGP-CL wearing has strong modification on wavefront aberrations probably due to its molding effect on corneal surface,which reduces the bilateral symmetry.High order wavefront aberration can be modified by Soft-CL wearing.
