Chinese Medical Ethics 1995;0(02):-
Objectives: To find out influencing factors of quality of life(QOL) of staffs in Centers for Disease Prevention and Control(CDC),whose results would be taken as theoretical evidence for government policy-makers to work out strategy of health human resources.Methods: The WHO Quality of Life Brief Scale(WHOQOL-BREF) was employed as the assessing tool for staffs of CDC who were in a city and its neighborhood counties.Each subject was asked to complete a spot self-assessment.Results: There is no significant difference of QOL of staffs between city and neighborhood county.Working at different departments was one of the influencing factors on psychological and social domains.Harmonious family relationship,good appetite,agreement to work competition,and confidence in working institutes were influencing factors to the total score of QOL.Conclusions: Scores of QOL of CDC staffs were relatively low with various influencing factors.It is necessary for leaders of related departments to take countermeasures to improve the QOL of CDC staffs.

Applying the integrated teaching methods to the physiology theory education is helpful to cultivating students′abilities to think and practice the clinical ideation and application,inspiring their interests in study,evoking their ideation and enhancing their abilities to learn initiatively and solving problem independently.
4.Effect of fractalkine on neuroprotection
Chinese Journal of Pathophysiology 2000;0(12):-
The chemokine fractalkine primarily involves in chemotaxis,adherence and inflammation.Recently it has been discovered owning the ability of inhibiting cell death in neurons and glial cells,as well as protecting central nervous system from toxic damage.Fractalkine reduces the toxicity to neurons and glial cells mediated by excessive Fas L,glutamate(Glu) or lipopolysaccharide(LPS).In vivo neutralization of endogenous brain fractalkine signal pathway increases inflammatory cytokines secretion and neuronal cell death induced by LPS.Fractalkine may achieve its neuroprotective property through influencing expression of pro-apoptotic and anti-apoptotic proteins,intracellular Ca2+ level and inflammatory cytokines secretion via protein kinase B(PKB)/Akt and extracellular signal-regulated kinase(ERK)/MAPK pathways.

OBJECTIVE:To establish an HPLC method for the determination of related substances in Donepezil hydrochloride tablets.METHODS:The separation was performed on AlltimaTM C18 column with mobile phase consisted of 0.01 mol?L-1 dipotassium hydrogen phosphate(3% triethylamine,pH=4.3)-methanol(60 :40) and flow rate of 1.0 mL?min-1.The detection wavelength was set at 271 nm and the column temperature was maintained at 35 ℃.The content of related substance was calculated by self-control with main component.RESULTS:Related substances were completely separated from the main constituent and the impurities were separated well from each other.The determination limit was 0.05 ng and the contents of related substances were 0.42%.CONCLUSION:The method is specific,sensitive and reproducible for the determination of related substances in Donepezil hydrochloride tablets.

Objective To study the effect of Bushen Tiaojing Chinese herbs on the expressions of endometrial integrin ?3 in infertile patients with polycystic ovary syndrome (PCOS) receiving ovulation induction therapies. Methods Thirty-six PCOS related infertility patients were divided into 2 groups at random, receiving different ovulation induction therapies:17 patients of group A were given clomephine citrate (CC)/human chorionic gonadotropin (hCG) therapies, and 19 patients of group B were given CC/ hCG combined with Chinese herbs therapies. 22 infertile women with fallopian tubal or male infactors were chosen as controls. The mRNA expressions of integrin ?3 in midluteal endometrium were measured by reverse transcription-polymerase chain reaction. Results Compared with controls, the expressions of endometrial integrin ?3 were weaker in group A (P0.05). Conclusion CC/hCG ovulation induction therapies may induce the decline of endometrium receptivity during midluteal phase, which Chinese herbs may promote.

The authors used a microvascular corrosion cast/scanning electron microscopy (SEM) technique to study the microvascular bed of the muscles of the medial pterygoid and masseter in two normal babies. The cast were prepared by perfusing the microvascular vessels with methyl methacrylate. Under SEM, the patterns of branches of the arteriole are: 1. tree like ramifications; 2. symmetrical branching; 3. fine plexiform branching. Moreover, the casts of arterial and venous vessels showed on their surfaces the typical imprint of the endothelial lining. Therefore, the venous vessels could be easily identified by the round nuclei of the endothelial cells of the venous vessels. On the other side, arteries and arterioles displayed spindle shaped nuclear imprints, oriented along the direction of the vessel. The morphological and functional characterization of the imprint of the precapillary sphincter and the two-grade anastomoses of the arcade arteries. The diameter of the capillary casts (mean?SE) was 5.6?1.9?m. Two or three capillaries join together to form a postcapillary venules, sometimes a single capillary reaches a major venous trunk was observed. These structural features were considered to play an important physiological role in the microcirculation in skeletal muscle.

Objective To explore efficacy of minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of distal tibia comminuted fracture by using normal anatomical plate. Methods Between January 2007 and July 2008,18 cases of distal tibia facture were treated by MIPPO using anatomical plate. The clinical data of the patients were reviewed. Results A mean of 6.5 cm incision (5.0-8.5 cm) was made in the patients; the intraoperative blood loss ranged from 60 to 300 ml (mean,145 ml);and the operation time ranged from 30 to 120 min with a mean of 63 min. After the surgery,2 patients developed mild skin necrosis,and was then cured by conventional therapy; no patient had nonunion of the fracture,failure of internal fixation,or delayed wound healing. The 18 cases were followed up for a mean of 8 months (range,4 to 10 months); all of them were healed clinically and could walk without crutch in 4 months postoperatively. According to Johner-Wruhs score system,11 were excellent and 7 were good; the excellent-good rate was 100%. Conclusions MIPPO with anatomical plate is an optimal treatment for distal tibia comminuted fracture with advantages in protecting the soft issues and bony blood supply,promoting the wound-healing process,and reducing the rate of complications.
