Objective: To research and establish an analysis model for chemical drug standards to provide the reference for the standard exploration jobs. Methods:The standard variation was studied by comparing and analyzing every version standard for the same drug to look for the change rule. Results:The standard items of the drug had some change rules in indicator numbers, testing methods and limits according to the order of issue time. The standard development trends could be described by making specific indicators and drawing evolution figures of the items. Conclusion:By the standard analysis model, the same item of the same drug can be compared to provide the reference for data collecting of experts. Meanwhile, formulate standard can be calculated to provide the reference for the standard improvement without drug standards.

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

Objective To investigate the clinical effect of mild hypothermia on neonatal bilirubin encephalopathy, and the value of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT and amplitude integrated electroencephalogram (aEEG) for diagnosis and evaluation of curative effect. Methods From May, 2013 to December, 2014, 29 newborns with bilirubin encephalopathy were divided into conventional group (n=15) and mild hypothermia group (n=14). The conventional group received conventional therapy, and the other group received mild hypothermia in addition. The aEEG and neuron-specific enolase (NSE) were measured before and after treatment, as well as the glucose metabolism rate with 18F-FDG PET/CT after treatment. Results The NSE was lower after treatment in both groups (t>9.670, P<0.001), and was lower in the mild hypothermia group than in the conventional group (F=46.146, P<0.001). After treatment, sleep-wake cycle (SWC), epileptiform activity and the degree of abnormality were obviously improved (P<0.05), and were better in the mild hypothermia group than in the conventional group (P<0.05). The cerebral glucose metabolism rate was significantly better in the mild hypo-thermia group than in the conventional group (t>2.943, P<0.01). The cerebral glucose metabolism rate was negatively correlated with aEEG and NSE (r>0.640, P<0.05). Conclusion Mild hypothermia therapy could further promote the energy metabolism of brain cells in neonatal bilirubin encephalopathy. 18F-FDG PET/CT and aEEG can be used for early diagnosis and therapeutic evaluation.

OBJECTIVETo compare the therapeutic differences among scalp acupuncture combined with auricular point sticking, body acupuncture and western medication for treatment of vascular dementia (VD).

METHODSNinety cases were randomly divided into a combined therapy group (31 cases), a body acupuncture group (29 cases) and a western medication group (30 cases). The combined therapy group was treated with scalp acupuncture at forehead middle line, parieral middle line, temporal front line and temporal rear line as well as auricular point sticking at naogan (AT3,41), shen (CO10), shenmen (TF4), zhen (AT3), once a day; the body acupuncture group was treated with acupuncture at Baihui (GV 20), Fengchi (GB 20), Zusanli (ST 36) and so on, once a day; the western medication group was treated with oral administration of aniracetam tablets, 0.2 g per time, twice a day. Fourteen days were considered as a treatment course, and totally 3 courses were required. The mini-mental state examination (MMSE) and activities of daily living (ADL) were applied to assess the changes of cognitive behavior ability before and after treatment among three groups. Also the efficacy among three groups were compared.

RESULTSOne case dropped out in the body acupuncture group and western medication group, respectively. The total effective rate was 90.334 (28/31) in the combined therapy group, which was superior to 85.734 (24/28) in the body acupuncture group and 79.3% (23/29) in the western medication group (both P < 0.05). After the treatment, the scores of MMSE and ADL were all improved among three groups, which was the most significant in the combined therapy group (MMSE: 23.32 +/- 4.45 vs 21.23 +/- 4.13, P < 0.05; 23.32 +/- 4.45 vs 20.41 +/- 4. 01, P < 0.01; ADL: 53.18 +/- 21.55 vs 51.92 +/- 20.42, P < 0.05; 53.18 +/- 21.55 vs 49.42 +/- 19.43, P < 0.01).

CONCLUSIONThe scalp acupuncture combined with auricular point sticking could improve the clinical symptoms and cognitive behavior ability in patients with vascular dementia, which has superior total efficacy to body acupuncture and western medication aniracetam tablets.

Background:As a congenital malformation that results in infertility and an inability to have vaginal intercourse,Mayer-RokitanskyKüster-Hauser (MRKH) syndrome places a considerable psychological burden on patients,which results in anxiety symptoms.However,only single case studies or a few small to medium-sized cross-sectional studies were identified to focus on anxiety symptoms in MRKH patients.Thus,the aim of this study was to explore the status of anxiety symptoms and the related factors in patients with MRKH syndrome.Methods:This cross-sectional study involving 141 patients with MRKH syndrome and 178 healthy women was conducted from January 2018 to December 2018.All participants were required to complete a demographic questionnaire and the Generalized Anxiety Disorder 7-item scale (GAD-7),Patient Health Questionnaire-9,Eysenck Personality Questionnaire-Revised,Short Scale for Chinese,and Chinese Version of the Female Sexual Function Index.The main outcome was the anxiety symptoms measured by the GAD-7.Main outcome was compared between the MRKH syndrome group and the healthy control group.Then,we explored the related factors by comparing patients with and without anxiety symptoms.Results:Of the respondents,24.1％ experienced moderate to severe anxiety symptoms.Patients with MRKH syndrome manifested more severe anxiety symptoms than healthy women.Negative self-evaluation of femininity (odds ratio [OR] 2.706,95％ confidence interval [CI] 1.010-7.247),neurotic personality traits (OR 1.100,95％ CI 1.029-1.175),and coexisting depressive symptoms (OR 4.422,95％ CI 1.498-13.049) were more prevalent in anxious patients.Conclusion:The findings stress the importance of anxiety symptom screening in MRKH patients and identify patients at risk of anxiety symptoms,providing a possible basis for future intervention.

To review the challenges and countermeasures in the hospital care for Wenchuan earthquake casualties and draw lessons for the protective response in the future. Medical records and laboratory findings of the victims admitted in West China Hospital (WCH) were retrospectively analyzed. Related data were compared between beforemath and aftermath of the earthquake and between WCH and frontier county hospitals. One thousand and thirty-one earthquake survivors were hospitalized, 1 358 victims underwent surgery and 142 victims were transferred to intensive care unit. The incidence of infection, crush syndrome and multiple organ dysfunction syndrome (MODS) was 39.6%, 20.7% and 2.3% respectively. Wound classification showed that the incidence of extremity damage was 72%, while the incidence of chest trauma, abdominal trauma and brain trauma was less than 10% respectively. Isolating rates of environmental pathogens were increased in the aftermath of earthquake, and the spectrum of the pathogens and related antibiotic sensitivities were quite different from those in the beforemath of earthquake. The social economic and population conditions in the earthquake-stricken areas affected the composition of the victims and the geographic features restricted the efficiency of rescue. Trauma-induced MODS, crush syndrome and severe infections all constituted the dilemma for the hospital care, to resolve whether the multidiscipline team work was proved to be an optimizing choice. For a more effective disaster protective response in the future, the study on rescue plan and the ladder therapies for massive casualties should be potentiated.

?AlM: To compare the clinical effect between small-incision cataract surgery and phacoemulsification.
?METHODS: Totally 93 patients ( 124 eyes ) with age-related cataract who received treatment in Mar 2010 and Feb 2013 were dicided into 2 groups randomly. Forty-two patients ( 59 eyes ) in group small - incision cataract surgery ( SlCS ) were treated by SlCS, while other 51 patients ( 65 eyes ) in group Phaco were treated by phacoemulsification. And then, postoperative visual acuity, corneal astigmatism, surgically induced astigmatism ( SlA ) and intraoperative and postoperative complications were contrasted between groups.
?RESULTS: After 1d and 1wk of postoperation, there were 38 eyes ( 64. 4%) and 41 eyes ( 69. 5%) having a better visual acuity of 0. 5 in the SlCS group, while there were 29 eyes (44. 6%) and 32 eyes (49. 2%) in the Phaco group. The vision of SlCS group was better than that of Phcao group (χ2 = 4. 877, 5. 242, P < 0. 05 ). On postoperative 1 and 3mo, with acuity of 0. 5 or better, eye numbers showed no statistically significant differences between two groups (χ2 = 0. 005, 0. 085, P>0. 05). The average corneal astigmatism used analysis of repeatedly measuring designing variance: Comparing the corneal astigmatism in intra - groups at different times, it was statistically significant (F=25. 624, P<0. 05), and had a tendency to decrease with time. However, there was no statistical significance for corneal astigmatism between groups (F=0. 986, P>0. 05). The coneal astigmatism of each group was higher at 1wk after the surgery than that of preoperation, and the contrast had statistical sigenficence (t=2. 906, 2. 427, P<0. 05). The Phaco group with SlA was lower than the SlCS group at 1wk and 1mo after the surgery (t=-4. 628, 2. 770, P<005). lt had no statistical significance in SlA by comparing with the two groups at 3mo after the surgery (t=0. 754, P>0. 05). There were statistical differences in SlA at different time both by intra-group comparison and group comparison ( F=26. 37, P<0. 05, F = 14. 29, P<0. 05). The comparison of posterior capsule rupture, the postoperative corneal edema and anterior chamber pigment membrane reaction in two groups showed no statistical significance.
?CONCLUSlON: Our research shows that small-incision cataract surgery and phacoemulsification had similar effect in the treatment of cataract. Phacoemulsification is not the only surgery option for the best treatment effect. Small- incision cataract surgery can be popularized in basic- level hospitals, achieving the effect similar to phacoemulsification.

Objective To evaluate the effect of acupuncture therapy of She medicine on cerebral hemodynamics in migraine patients, and to further verify its therapeutic efficacy and preliminarily reveal the action mechanism in treating migraine. Method 120 Eligible subjects were randomized into two groups. The treatment group was intervened by acupuncture of She medicine, while the control group was intervened by Western medication, 10 d as a treatment course, for 2 courses in total at a 2-day interval. Transcranial Doppler (TCD) was adopted to observe the average blood flow velocity of cerebral arteries before and after the treatment. Result The total effective rate was 82.8% in the treatment group versus 71.4% in the control group, and the difference was statistically significant (P<0.05) by rank-sum test. Before the treatment, the abnormity rate of cerebral artery blood flow was 62.8% in the treatment group versus 61.9% in the control group, and the between-group difference was statistically insignificant (P>0.05), indicating the comparability; after the treatment, the abnormity rate of cerebral artery blood flow was 25.9% in the treatment group versus 35.3% in the control group, and the between-group was statistically significant (P<0.05). Conclusion Acupuncture of She medicine is effective in treating migraine, and it can significantly improve the cerebral hemodynamics.
