OBJECTIVE: To optimize the prescription of traditional Chinese medicine for motion sickness (MS).METHODS: Zingiber officinale,Herba pogostemonis,Aucklandia lappa were extracted respectively,and rotating-inducing MS mice were enrolled in uniform design.The prescription was optimized with MS index as the parameters.RESULTS: The optimal prescription was as follows:60 g Z.officinale,45 g Herba pogostemonis,5 g A.lappa.The extractive of prescription was significantly better than dimenhydrinate in the treatment of MS.CONCLUSION: MS index is a stable and sensitive parameters and it is suitable for screening and evaluation of anti-MS drugs.R.zingiberis,H.pogostemonis,A.lappq are potential drug for MS.

Objective To investigate the effect of hyperphosphatemia on type Ⅱa sodium dependent phosphate cotransporter (NaPi-2)mRNA expression in the kidneys of 5/6 nephrectomized (STNx)rats and evaluate the interference of Renagel. Methods Forty-two male Sprague-Dawley rats underwent 5/6 nephrectomy or sham operation. The animals were then divided into seven groups: (1)STNx+high-Pi diet(HP) group (1.2%P); (2)STNx+low-Pi diet(LP) group(0.2%P); (3)STNx+ normal-Pi diet (NP) group; (4)STNx+HP+Renagel-treated (Ren)group; (5)sham+HP group; (6) sham+LP group; (7)sham+NP group. Serum ionized calcium (iCa) , phosphorus, and iPTH levels were detected at day 2,7,14.The kidneys were removed after the rats were sacrificed on day 14 and serum 1,25-(OH)2D3 and FEp were measured. RT-PCR was applied to examine NaPi-2 mRNA. Results Serum P and iPTH levels in STNx+HP group were significantly higher than those in STNx+ LP and 3 sham groups (P0.05)among these five groups mentioned above. Serum P and iPTH levels in Renagel-treated group were much lower than those in STNx+HP group (P

Objective To investigate the clinic results of treatment of distal tibiofibular fractures by in- direct reduction and plate fixation through inferior fibula.Methods Between 2002 and 2005,32 cases of distal tibiofibular fractures were treated with indirect reduction and plate fixation through inferior fibula.According to the AO/ASIF classification,there were 17 cases of type A,nine cases of type B,and six cases of type C.Twenty of them also received iliac autograft through a limited median incision at the lower tibia to repair their lateral tibial defects.After operation their ankle joints were fixated at 90?with piaster brace and cast for three months.The bone union,wound and the function of the ankles were observed after surgery.Results All the patients were followed up for an average of 16 months.The average bone union time was 14 weeks.No nonunion,screw loosening,broken plate,or infection of the wounds was found in this series.The excellent and good rate was 84.4% according to Mazur's ankle joint function scoring.Conclusion Indirect reduction and plate fixation through inferior fibula is a satisfactory technique in the treatment of distal tibiofibular fractures.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

Objective:To investigate the relationship between the department where patients with nasopharyngeal carcinomas was first admitted and the delayed diagnoses(or misdiagnosis).Methods:The data of 1998 cases of nasopharyngeal carcinomas were collected and analyzed.Results:The department of otolaryngology and the radiation oncology have the high correction rates for the first diagnosis,but misdiagnosis rates in departments of surgical,internal medicine and traditional Chinese medicine were very poor.Conclusion:The clinical knowledge about nasopharyngeal carcinomas was the most important factor for the first diagnoses.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

BACKGROUND:Negative pressure wound therapy has been extensively used, but most people only knew the superiority of negative pressure wound therapy based on clinical experiences or subjective judgment.
OBJECTIVE:To observe the effects of negative pressure wound therapy on the wound on the body surface, and to compare with contemporaneous conventional method.
METHODS:A total of 45 patients with wound on the body surface treated in the Peking Union Medical Col ege Hospital from January 2006 to December 2011 were enrol ed in this study, including 25 patients undergoing negative pressure wound therapy and 20 patients undergoing conventional change dressing method. Al clinical data were recorded.
RESULTS AND CONCLUSION:Negative pressure wound therapy was better than conventional method (P<0.05), on terms of preoperative preparation period, wound granulation, bacterial scavenging, labor intensity of working staff and incidence of postoperative complications. However, no significant difference in therapy cost was detectable (P>0.05). These results suggested that compared with conventional method, negative pressure wound therapy positively contributed to the healing, obviously shortened preoperative preparation, accelerated the diminution of wound, decreased the incidence of complications of reconstruction, lessened patient’s distress, reduced their economic cost, and diminished labor intensity of working staff. Negative pressure wound therapy has been proven an excellent tool of to promote wound healing.
