Anatomic segmental hepatectomy,as an important part ofprecision surgery,has been accepted and widely applied as the promotion of precision hepatectomy.Anatomic segmental hepatectomy is superior to non-anatomical hepatectomy in clinical efficacy,application scope and operation techniques.There are many operation techniques developed by surgeons to accomplish segmental hepatectomy,and it is worthy for spreading in clinical practice.

The paper is to report the establishment of three methods for determination of methyl salicylate-2-O-beta-D-galactopyranoside (1-4)-beta-D-glucopyranoside (MSG) by HPLC, UV or potentiometric titration. The results determined by the three methods turned out to be of no significant difference (P>0.05). The method was chosen according to MSG difference test demands.

Objective:To evaluate the effectiveness of microport extraction of the impacted mandibular third molar removal.Meth-ods:According to the systematic review and meta-analysis,the randomized controlled clinical trials published till October 2012 were searched and collected using the method of evidence-based medicine.Results:8 clinical research papers including 1 915 subjects were collected.Complication of microport extraction(958 cases)was less than that of traditional operation(957 cases).Conclusion:Microport extraction of impacted mandibular third molar may reduce the complications.

Objective To compare the clinical value of uterine submucosal myoma classification by two dimensional and three-dimensional contrast-enhanced ultrasonography and surgical pathologic results.Methods The imaging data of ultrasonographic hysterography including 2D and 3D of 124 patients with uterine submucosal myoma were retrospectively analyzed,and the results were compared with the surgical pathologic results.The diagnostic accuracy of uterine submucosal myoma classification and the operation success rate of uterine submucosal myoma for Ⅰ grade by ultrasonographic hysterography including 2D and 3D were compared.Results The patients were diagnosed pathologically with 0,Ⅰ and Ⅱ grade of uterine submucosal myoma in 26 cases,52 cases,68 cases,respectively.The patients were diagnosed by 2D ultrasonic sonohysterography with 0 grade,Ⅰ grade and Ⅱ grade of uterine submucosal myoma in 26 cases,62 cases,58 cases,respectively.The patients were diagnosed by 3D ultrasonic sonohysterography with 0,Ⅰ and Ⅱ grade of uterine submucous myoma in 26 cases,52 cases,68 cases,respectively.For pathological results as thegold standard,the diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for 0 grade by 2D and 3D ultrasonic sonohysterography were all 100.00％.The diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for Ⅰ and Ⅱ grade by 2D ultrasonic sonohysterography were 92.32％,79.46％,85.00％,respectively.The diagnostic sensitivity,specificity and accuracy of uterine submucosal myoma for Ⅰ and Ⅱ grade by 3D ultrasonic sonohysterography were 96.24％,88.24％,91.76％,respectively.There were significant differences in the diagnostic sensitivity,specificity and accuracy of submucosal myoma of uterus for Ⅰ and Ⅱ grade by 2 D and 3 D ultrasonic sonohysterography (x2 =3.21,2.78,2.17,2.33,all P ＜ 0.05).The patients diagnosed as uterine submucous myoma for 0 grade all underwent the hysteroscopic surgery for successful resection,while the patients with uterine submucous myoma for Ⅱ grade underwent laparoscopic surgery or open surgery.The operation success rates of uterine submucous myoma for Ⅰ grade by hysteroscopic surgery diagnosed by 2D and 3D ultrasonic sonohysterography were 75.81％,98.07％,respectively.The operation success rate of uterine submucous myoma for Ⅰ grade by hysteroscopic surgery diagnosed by 3D ultrasonic sonohysterography was significantly higher than that diagnosed by 2D ultrasonic sonohysterography (x2 =7.15,P ＜ 0.05).Conclusion The accuracy of uterine submucosal myoma classification by 3D ultrasonographic hysterography is better than 2D ultrasonographic hysterography.

Objective To study the chemical constituents of Clematis manshurica. MethodsThe extract from the roots and rhizomes of C. manshurica was subjected to chromatography on silica gel and Sephadex LH-20 column. The compounds obtained were identified on the basis of their physicochemical and spectroscopic evidences. ResultsEleven compounds were isolated and their structures were elucidated as squalene (Ⅰ), friedelin (Ⅱ), hexacosoic acid (Ⅲ), ?-sitosterol (Ⅳ), stigmasterol (Ⅴ), oleanolic acid (Ⅵ), ?-daucosterol (Ⅶ), 5-hydroxymethyl-2-furaldehyde (Ⅷ), methyl 3, 4-dihydroxy-phenyl lactate (Ⅸ), 5R-dihydro-5-hydroxymethyl-2(3H)-furanone (Ⅹ), 5R-5-hydroxymethyl-2(5H)-furanone (Ⅺ). ConclusionAll the compounds except for ?-sitosterol are isolated from the plant for the first time.

In order to reform the medical talent evaluation system, establish evaluation systems of physician competency, and implement physician resources management systems according to work position, and the compensa-tion system which reflects the value of medical services, The basic principles and standards of different physician tiers and grades are created in Shenzhen based on literature review, expert consultation and the methods from the American Centers for Medicare and Medicaid Services ( CMS) . Some results have achieved, including medical competency as-sessment of a certain number of physicians in the pilot project ( the coincidence rate of special hospitals is higher than general hospitals, respectively 78. 9% and 44. 8% ), comprehensive personnel systems reforms in public hospi-tals, and the trial selection of medical talents. The paper also provides some implications:The cognition of all sectors of society and physician themselves should be improved, Transitional policies for position recruitment and performance pay needs further improvement. Meanwhile, the grade evaluation system of non-physicians must also be given greater attention.

Objective To definite the correlation of hip muscle density with proximal femoral fracture in the elderly.Methods The study included 41 proximal femoral fracture cases [14 males and 27 females,at age of (64.1 ±5.1)years] and 14 normal cases [4 males and 10 females,at age of (64.8 ± 3.9) years] that underwent CT examination for hip joint.In fracture group,19 cases sustained femoral neck fracture and 22 intertrochanteric fracture.CT imaging data were reviewed to analyze the correlation of age with hip muscle density at the level of ischium tubercle.Hip muscle density was compared between fracture side and healthy side in fracture group and between control group and fracture group.Results Hip muscle density showed a downward trend with increased age (P ＜ 0.05).Hip muscle density did not differ significantly between fracture side and healthy side in fracture group (P ＞ 0.05).Regardless of age,gender and other factors,hip anterior muscle density [(34.8 ± 4.1) Hu] and posterior muscle density [(22.1 ±5.5) Hu] were lower in fracture group than in control group [(44.4 ±5.7)Hu,(39.2 ±5.3)Hu respectively,P ＜ 0.05] but there was no significant difference in hip medial muscle density between the two groups (P ＞ 0.05).Conclusions Hip muscle density decreases with age and has no strong correlation with fracture.Deadline of the hip muscle density may be a risk factor to proximal femoral fracture in the elderly.

AIM: To explore the effect of bone marrow-derived mesenchymal stem cells (BMSCs) combined with vitamin E on the inflammatory reaction in acute kidney injury ( AKI) rats.METHODS:Gentamicin was used to in-duce AKI and the rats were treated with BMSCs combined with vitamin E.After treatment, the rat plasma and kidney tis-sues were collected, and the expression of inflammatory factors at mRNA and protein levels was detected by real-time quan-titative PCR and ELISA.RESULTS:After the treatment with BMSCs combined with vitamin E, the inflammatory proteins were down-regulated in the plasma and the renal tissues.Compared with single treatment group, the decreases in the in-flammatory proteins were more obvious in combined treatment group.CONCLUSION: The method of BMSCs combined with vitamin E takes the anti-inflammatory effect on AKI, indicating a new and potential mode in clinical application for AKI therapy.
