Objective: This study aims to investigate the positive practice environments evaluation of doctors in public hospital and provide suggestions for Chinese health care reform from the perspective of health service providers.Methods: Using self-designed questionnaire, a national cross-sectional survey was performed in 77 public hospitals across seven provinces/ metropolis, involving a total of 3564 doctors.Positive practice environment includes organizational management and doctor-patient two-dimension relationships.Results: The doctor''s mean score of positive practice environment evaluation was 18.02±4.86 (out of 40).Doctors had a higher evaluation (score) of organizational management than doctor-patient relationship.In the organizational management dimension, the personal advice got the lowest scores(2.24±1.04);and in doctor-patient relations, evasion of medical risk got the lowest scores(1.59±0.81).There was a difference in the positive practice scores of physicians in different regions, and the scores of doctors from the western China were the lowest (P<0.001.Doctors from western medicine hospitals had lower evaluation of positive practice environments than ones from Chinese Traditional Medicine hospitals(P=0.002.Conclusion: As per the analysis conducted in this investigation, the current medical practice environment of doctors in China is not a promising one.Doctor-patient relationship is worse than organizational management.Hospitals should adopt a participatory decision-making model in management and establish a broadband performance based compensation to motivate junior doctors.Besides, government should establish reasonable compensation incentive mechanism, with the aim of promoting doctor-patient trust.

OBJECTIVETo analyze the relationship between Chinese medical constitutions and chemotherapy-induced leucopenia (CIL) of primary breast cancer patients.

METHODSTotally 306 breast cancer patients undergoing adjunctive chemotherapy for the 1st time, and effective 291 breast cancer patients were recruited in this study.Nine Basic Constitutional Scale was used before first chemotherapy. Chinese medical constitutions were classified and quantitatively scored. The highest grading for any item of adverse reactions in each case during the whole chemotherapy course was recorded after chemotherapy. Data were statistically analyzed using SPSS16.0.

RESULTSThere was no significant difference in CIL between different chemotherapy regimens and various Chinese medical constitutions of breast cancer patients (P > 0.05). Yang deficiency constitution is one risk factor for CIL. The higher the score of yang deficiency constitution, the more severe the CIL.

CONCLUSIONSYang deficiency constitution was correlated with the degree of CIL. The higher the score of yang deficiency constitution, the greater the risk of III-IV grade CIL in breast cancer patients.

Objective: To determine the effect of polygona-polysaccharose (PP) on learning and memory ability in rats with Alzheimer’s disease (AD). Methods: Forty ifve Sprague-Dawley rats were assigned into 3 groups. Rats in the sham-operated group were injected with normal saline. Rats in the Aβ group were injected with Aβ1-42. Rats in the PP group were injected with 16% PP solution for 45 days consecutively. hTe Morris water maze was used to investigate the ability of learning and memory in the rats. hTe effect of Aβ and PP on the hippocampus cells was observed by HE and Congo red staining of methanol. Results: Rats in the sham-operated group had no obvious morphological change; and morphology of rats in the PP group was basicaly normal. The layer of pyramidal cells in the Aβ group was decreased. hTe cells appeared sparse and irregular and became smaller. Karyopyknosis and vacuolardegeneration cells were also found. More positive staining materials aggradated in the Aβ group compared with the PP group by Congo red staining (P<0.05). Conclusion: Aβ infusion into the hippocampus results in the impairment of the neuronal degeneration in the rats, which shows similar characterizations of AD. PP can reduce the deposition of Aβ in the hippocampus.

OBJECTIVETo optimize formulas of Quban gel.

METHODThe U6 (6(2) x 3) uniform design was adopted to optimize gel formulas, with rheological parameters, such as viscosity and yield value in room temperature, viscosity and yield value in average temperature of skin, thixlotropy.

RESULTThe optimum proportion of matrix was made of 1.0 g carbomer 940, 5 mL glycerin and pH value 5-6.

CONCLUSIONThe regression model for gel matrix quality and gel rheological parameters was established to directly reflect the impacting effect of various factors, and provide certain preference basis for the screening of gel matrix formulas. Quban gel prepared by the method was evenly distributed, moderately viscous and highly thixotropic

Objective:To observe the clinical effect of acupoint sticking of Chinese medicine at Shenque (CV 8) for preventing spleenstomach disharmony caused by venous analgesia pump.Methods:A total of 120 post-surgery patients using venous analgesia pump and also conforming to the inclusion criteria were randomized into 2 groups by the random number table.There were 58 patients in the control group who received conventional post-surgery nursing care,and there were 62 patients in the treatment group who received acupoint sticking at Shenque (CV 8) on the basis of conventional nursing care.After treatment,the incidences of postoperative nausea and vomiting,and abdominal bloating were measured.Results:The total incidence of nausea,vomiting and abdominal bloating in the treatment group was 11.3％,versus 39.7％ in the control group,and the difference of the incidence between the two groups showed a statistical significance (P＜0.05).In comparison of the severity of spleen-stomach dishormony which happened during 72 h after surgery,cases in the treatment group showed lower severity than those in the control group (P＜0.05).Conclusion:Acupoint sticking at Shenque (CV 8) can effectively prevent spleen-stomach disharmony caused by venous analgesia pump,which will alleviate sufferings of the patients.

OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.

AIMTo report the experience with single stage dorsal inlay buccal mucosal grafts using the Snodgrass technique for complex redo cases.

METHODSFrom May 2004 to December 2005, a total of 53 patients aged from 3 to 34 years old (average 11.62 +/- 7.18 years) with failed previous hypospadias surgery were included in the present study. Indications included urethral strictures and repair breakdown. The unhealthy urethra was unroofed from the meatus in the ventral midline, a buccal mucosal graft was inlayed between the incised urethral plate and fixed to the corpora cavernosa. The neourethra was tubularized, and covered with subcutaneous (dartos) tissue and penile skin. Glanuloplasty was also performed in all cases. Outcome analysis included clinical follow-up, and endoscopy in 2 selected cases.

RESULTSThe buccal mucosal graft was 3.0-7.5 cm in length and 0.7-2.0 cm in width. All patients required glanuloplasty, with buccal mucosal grafts extended to the tip of the glans. After a follow-up of 14-30 months (mean 22.6 months), the total complication rate was 15.1%, with five cases of fistula and three cases of stricture.

CONCLUSIONInlaying dorsal buccal mucosal grafts applying the Snodgrass technique is a reliable method for creating a substitute urethral plate for tubularization. The recurrent rate of urethral stricture and fistula is at an acceptable level for redo cases. This approach represents an effective, simple and safe option for reoperations.
