This paper briefly describes China-produced Resina Draconis in respect to the sources of original plant,refining process, chemical compositions,quality analysis and present status of its application in China.

This paper briefly describes the manufacture of active vitamin E capsules utilizing high bioavailability technique. Experimental results demonstrate that the product shows good dispersivity,stable quality and no side effects. The bioavailability of the new product is more than 3 times that of commonly used vitamin E capsules, so it has satisfactory curative effect and salty in use.

BACKGROUND: There are many criteria used to evaluate the curative effects of hip-preserving treatment for osteonecrosis of the femoral head (ONFH), and there have been no consistent criteria, so the curative effects of hip-preserving treatment lack comparability to some extent. OBJECTIVE: To review and analyze a variety of criteria for evaluating the curative effects of hip-preserving treatment and to develop a specific quality of life scale of hip-preserving treatment. METHODS: A computer-based retrieval of Pubmed database using key words "osteonecrosis, femoral head, quality of life", or "osteonecrosis, femoral head, curative effect" for manuscripts published from August 2000 to August 2010 and of CNKI database for manuscripts published from January 1994 to December 2009 using key words "femoral head necrosis, curative effect" or "femoral head necrosis, quality of life". Manuscripts that address hip-preserving treatment of ONFH and related quality of life or manuscripts that were recently published or in the high-impact journals were included in this paper. Finally, 31 manuscripts were reviewed.RESULTS AND CONCLUSION: The current criteria for evaluating the curative effects of hip-preserving treatment focus on pain, function, and range of motion of hip joints, but do not lay emphasis on the local changes of hip joints or lower limbs, which can not sufficiently reflect the overall quality of life of patients. The SF-36 scale lack specificity to some extents and cannot be used to evaluate the curative effects of hip-preserving treatment systemically and specifically. Therefore, it is necessary to develop a specific quality of life scale for evaluating the curative effects of hip-preserving treatment of ONFH.

The article enunciates the importance of studying and exploiting medical virtual laboratory for reforming undergraduate experimental teaching modes, improving experimental teaching qualities by expounding the conditions and characteristics of constructed medical virtual laboratory, analyzing the implementation and effectiveness of medical virtual laboratory.

Bladder cancer is a common tumor with a high rate of recurrence and quick progression.Many biomarkers for the detection of bladder cancer have been identified,but none has been reported to date to have sufficient sensitivity and specificity.Recent researches are concentrated on p53,Rb,Cyclin D,P27kip-1,FGFR3,Cadherin,Survivin,Aurora,MMP,VEGF and DNA Methylation.In spite of their different sensitivities for bladder cancer of different stages or degrees,these biomarkers are valuable for its diagnosis and prognosis.

Objective To investigate the technique and outcome of primary management of skull base fracture and cerebrospinal fluid (CSF) leakage by emergency surgery in patients with severe craniocerebral trauma. Methods A total of 16 patients with severe brain injury, skull base fracture and CSF leakage hospitalized in Department of Neurosurgery, Tianjin Medical University General Hospital from January 2014 to December 2015 were retrospectively analyzed. All of patients underwent emergency surgery to remove the hematoma and repair the skull base fracture, including anterior skull base repair in 12 patients and middle temporal skull base repair in 4 patients. During the surgery, the inner wall of the frontal sinus was managed by electrocautery, then removal of frontal sinus mucosa, hydrogen peroxide and iodophor rinse were used. The repairing and forming of the orbital roof were performed for the severe deformation cases. All bone fractures and fissures were filled with muscle blocks and biological glue and covered with a pedicled muscle flap. In addition, after close suturing of epidural, the intact periosteum under the skin flap was used to tile the skull base. No external material was used in the whole process. Results Among the 16 patients, 14 (87.5%) patients were successfully repaired by emergency surgery, and 2 cases (12.5%) failed. One of the patients who failed to repair the fracture was with the middle skull base fracture, severe fracture of skull base and mastoid, and extensive exposure of mastoid air chamber with large bone mass. This patient failed secondary surgical repair and died with severe infection. Another one case who failed primary surgery was with severe bone fractures in the anterior, middle and posterior skull base, which could not be completely repaired. This patient was also combined with infection and dead ultimately. Conclusion Primary repair in patient with severe head injury combined with skull base fracture, which needs surgical intervention can reduce further injury and save the patient's life. The key to the operation is to determine the operative principle and to repair the skull base tightly.

In the genealogical investigation into 1210 patients with alopecia areata(AA), we found 75 cases with a positive family history of AA, the familial incidence was 6.2%. The incidence of AA in the 75 families (1093 cases) was 14.91% (163 cases). In these families, there were 142 patients in first-grade relatives of the family members, 17 in second-grade, and 4 in third-grade. We observed 70 cases in 33 families within one generation, 87 cases in 40 families within two succesive generations, and 6 cases in 2 families within three successive generations, four pairs of monozygotic twins appeared in this investigation, but just one of each pair was affected. The relationship between pathogenesis of AA and genetic factor has been discussed.
