Objective To discuss the effectiveness of tracer methodology in the training of intern medical record writing. Methods Fifty interns who received medical record writing training in July 2012 were set as control group and were trained by traditional methods. Meanwhile, 58 interns who received medical record writing training in July 2013 were set as investigation group and were trained by tracer methodology. Pre-training questionnaire survey was conducted for interns in investigation group and targeted training was provided. After the training, interns in two groups were surveyed by questionnaire of basic norms of medical record writing. Excel software was used to do data entry and SPSS 21.0 statistical software was used to statistical analysis. P<0.05 signifies statistical differences. Results Final record writing exam after the training demonstrated that there were significant differ-ences in basic requirement of record writing, basic principle of record writing, history taking, record time limit, contents of record writing and correct rate of patients' answer to the document between in-vestigation group and control group with statistical differences(P<0.05). Conclusion Tracer method-ology has obvious effects in intern medical record writing training and is worth popularization and ap-plication in clinical teaching.

Objective To investigate the effect of heart rate variability (HRV) biofeedback training on patients with three types of insom-nia disorder. Methods From June, 2016 to March, 2017, 17 patients in simple insomnia group, 19 patients in insomnia with anxiety group, and 19 patients in insomnia with depression group were included. All the patients received HRV biofeedback training and same medication (zolpidem tartrate, 10 mg every night). They were assessed with Pittsburgh Sleep Quality Index (PSQI), Symptom Checklist 90 (SCL-90), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD), and HRV parameters were tracked before and after training. Re-sults After training, the scores of PSQI, SCL-90, HAMA , HAMD and the ratio of low frequency (LF) and high frequency (HF) (LF/HF) de-creased in all groups (t>1.446, P<0.05). There was significant difference in PSQI among three groups (F=3.537, P=0.038). The D-values of the PSQI score and LF/HF before and after training were more in the insomnia with anxiety group and the insomnia with depression group than in the simple insomnia group (P<0.05), however, no significant difference was observed between the insomnia with anxiety group and the insomnia with depression group (P>0.05). Conclusion HRV biofeedback training could improve the symptoms of patients with three types of insomnia disorder, especially for those with anxiety or depression.

OBJECTIVE:To prepare domiphen bromide osmotic tablets,and to observe,analyze the mechanism of drug release.METHODS:Coating prescription was optimized by uniform design and the cumulative rates of drug release of different formulated preparations were measured,pharmaceutical features of domiphen bromide osmotic tablet and mechanism of drug release were studied.RESULTS:The dosage of PEG-400 and the coating membrane thickness all had an effect on drug release.The optimal coating technique was analyzed as 12%of PEG-400 and 10mg of coating.Spray speed,temperature and rotation speed did not affect releasing profiles.CONCLUSION:Improvement in formulation of coat of domiphen bromide osmotic tablet can result in drug release for 12h,whose mechanism includes diffusion and osmotic pump principle.

The technique of extracting and refining mucopolysaccharide from Dasyatis akajei cartilage obtained was studied and the content of mucopolysaccharide was measured.The results showed that when the content of NaOH was 6%,temperature 40℃, extracting time 6h,followed neutral protein enzyme dissolution for 7h under 40℃,protein precipitation with trichloroacetic acid and 4 times volume 95% C_(2)H_(5)OH for polysaccharide precipitation.the extraction rate was over 21%, the product was white powder and its purity was about (84.53%).Physical and chemical properties of the mucopolysaccharide were identified.

Objective To prepare Domiphen osmotic tablets of zero release above 80% in vitro. Methods Coating prescription was optimized by uniform design and the drug release characteristic was tested in vitro. Results The lemma thickness was (shown as lemma weight) 10.75 mg and the content of the porosity-making agent was 12%. The three batchs of drug tablets release pattern were in accord with zero order kinetics during 12 h. Conclusion This method is easy to produce and reaches initial devise request.

Objective To evaluate the effects of Xuefurong capsules,the traditional Chinese medicine for invigorating the kidney,on sexual function and expression of neuronal nitric oxide synthase(nNOS) in paraventricular nucleus(PVN) in adult castrated SD rats.Methods The male castrated rat model was made and three days after operation the liquid of Xuefurong capsules(5 mg/kg) was given by intragastric administration once a day for 28 days.The sexual function was observed and the nNOS expression in PVN was detected by using ABC immunohistochemical method.The number,area and gray degree of nNOS were counted and analyzed with semi-quantitative method.Results ①Compared with that in the castrated group,the serum testosterone level increased obviously in Xuefurong group(P0.05).Conclusion Xuefurong capsules can increase the level of testosterone,enhance the sexual function of castrated rats and nNOS expression in PVN.

Objective To evaluate the method of measurement of total scatter calibrate factor (Sc,p). Methods To measure the Sc,p at different depths on central axis of 6?MV, 15?MV photon beams through different ways. Results It was found that the measured data of Sc,p changed with the different depths to a range of 1%～7%. Using the direct method, the Sc,p measured depth should be the same as the depth in dose normalization point of the prescription dose. If the Sc,p ( fsz, d) was measured at the other depths, it could be obtained indirectly by the calculation formula. Conclusions The Sc,p in the prescription dose can be obtained either by the direct measure method or the indirect calculation formula. But emphasis should be laid on the proper measure depth.

METHODS: Through field processed investigation alcohol-macerated extracts and paenol content compared among the smoked, de-epidermis, drying and direct drying in the sun. RESULTS: Paeonia suffruticosa Andr. with the epidermis is better than others. CONCLUSION: The method of integrating field cutting crude drugs into pieces with processing of Paeonia suffruticosa Andr. has feasible standardization and industrial benefits.

OBJECTIVETo explore the eyelid's characteristics of outpatients who visited the plastic surgery clinic in 3rd Hospital of Peking University.

METHODSFrom Jan. 2007 to Feb. 2011, we collected facial images and general data of 2,183 outpatients, and divided them into groups according to their genders. The eyelid images were analyzed and epicanthus or foldless eyelid were recorded. Then the incidence rates of epicanthus and foldless eyelid were calculated.

RESULTSIn 2,183 patients (4,366 eyes), the incidence rate of epicanthus is 86.1% (3,760/4,366), and the incidence rate of foldless eyelid is 35.3% (1,541/4,366). In 178 males (356 eyes) and 2,005 females patients (4,010 eyes), the incidence rates of epicanthus are 78.4% (279/356) and 86.8% (3,481/4,010), respectively. The incidence rates of foldless eyelid are 48.0% (171/356) and 34.2% (1,370/4,010), respectively.

CONCLUSIONSThe incidence rates of epicanthus and foldless eyelid are relatively high for the outpatient population in the plastic surgery clinic of Third Hospital of Peking University.
