Objective To establish a RP-HPLC method for simultaneous quantitative determination of 4 anthraquinones in Shugan Quzhi capsules. Methods A RP-HPLC method was used with a Diamonsil C18 column (5 ?m,4.6 mm?150 mm). The mobile phase was composed of methanol and 0.1% H3PO4 water solution (77∶23,v/v). The wavelength of UV detector was 254 nm and column temperature was 30 ℃. Flow rate was 1.0 mL/min and 20 ?L was injected every time. Results The linear ranges of rhein,emodin,chrysophanol and physcion were 0.083 2～2.08,0.100 8～2.52,0.291 2～7.28 and 0.088～2.20 ?g/mL,respectively. Their average recoveries were 97.3%,96.9%,96.5% and 95.9%,respectively. Conclusion This method was sensitive,repeatable and suitable to determine the contents of 4 anthraquinones in Shugan Quzhi capsules.

Objective:To prepare the placebos of Sicao Tongmai capsules to provide the reference for the placebo preparation in clinical trials of traditional Chinese medicines. Methods: Taking the placebo preparation of Sicao Tongmai capsules as the example, the appearance, color and smell of the placebo were assessed by the scoring method and an electronic nose. Results:The appearance, color and taste of the placebo were in line with those of the drug powder, while there was difference in smell. The simulated clinical ex-periments showed that the placebo was difficult to be unblinded. Conclusion:The placebo can be used in TCM clinical trials, howev-er, the production technology should be further improved and modified.

Objective: To establish the preparation method of the placebos for Shenbawei capsules and objectively evaluate the simulation effects. Methods:Using the placebos for Shenbawei capsules as the example, a blind trial was used to assess and score the appearance, color and smell of the placebos. Results: The placebos were basically the same in the appearance, color and taste with the testing drugs. The results of the clinical trial simulation showed that the placebos were difficult to be unblinded. Conclusion:The placebos can be used in the clinical trial for Shenbawei capsules.

Objective: To determine the optimal preparation conditions for Huangmai granules. Methods: Using single factor screening method and orthogonal design method, the extraction process and granulation process were optimized. Results:The optimal preparation process was as follows:the medicinal materials in the prescription were extracted 3 times with 8-fold amount of water with 2h for each time. The water extract was combined followed by vacuum concentration, and then dried to obtain dry extract. The powder of dry extract was evenly mixed with dextrin at appropriate amount, and the wet granules were prepared with the 40% ethanol followed by drying and size stabilization to obtain the products. Conclusion:The selected preparation process is scientific, reasonable and sta-ble, and suitable for the industrial production.

OBJECTIVE:To establish a method for the quality control of Huangmai granules and provide reference for the qual-ity control. METHODS:TLC was conducted to identify the Leguminosae in Huangmai granules and HPLC was used to determine the contents of icariin,hyperin and stilbene glycoside in Huangmai granules. RESULTS:The spots on TLC plates were clear with good reproducibility. The results of HPLC showed that the linear range was 9.969-319.0 μg/ml(r=0.999 9) for icariin , 12.3-196.8 μg/ml(r=0.999 9)for hyperin and 12.64-202.2 μg/ml(r=0.999 8)for stilbene glycoside;RSDs of precision,stability and reproducibility tests were all no more than 2.92%;the average recoveries were respectively 95.44%(RSD=1.46%,n=6), 101.06%(RSD=1.90%,n=6)and 100.51%(RSD=1.73%,n=6). CONCLUSIONS:The method is simple,reproducible,accu-rate and reliable,and can be used for the quality control of Huangmai granules.

Objective: To investigate the stability of icariin, 2,3,5,4'-tetrahydroxy-stilbene-2-O-β-D-glucoside and hyperoside in Huangmai mixture.Methods: TLC was used to identify astrogaloside IV and Morindae officinalis Radix, and HPLC was used to determine the contents of icariin, 2,3,5,4'-retrahydroxy-stilbene-2-O-β-D-glucoside and hyperoside.The stability of Huangmai mixture under the conditions of accelerated testing and long-term testing was assessed.Results: Astrogaloside IV, Morindae officinalis Radix and icariin showed good stability during the accelerated testing and long-term testing.The contents of 2,3,5,4'-tetrahydroxy-stilbene-2-O-β-D-glucoside and hyperoside declined quickly during the stability testing.Conclusion: Hyperoside and 2,3,5,4'-retrahydroxy-stilbene-2-O-β-D-glucoside are unstable in Huangmai mixture.A novel solid dosage form of Huangmai should be developed to obtain better stability.

Electronic medical records (EMR) is the clinical diagnosis, guiding intervention and digital medical service record of outpatient, hospital patients (or care object) in medical institution. And it is the complete, detailed clinical information resource which has produced and recorded in all previous medical treatments. Radiotherapy electronic medical records contain texts, images and graphics, therefore the information is more complicated. This paper proposes an EMR information system based on DICOM-RT standard, through the use of seven objects of DICOM-RT to achieve the information exchange and sharing between different systems, equipments, convenient radiotherapy treatment data management, improve the efficiency of radiation treatment.

Objective: To analyze the uncertainty of quercetin concentration determination in Sicao Tongmai capsules by HPLC. Methods: The source of uncertainty was confirmed by analyzing the HPLC determination process. The uncertainty components were quantified by statistics, and the extended uncertainty and confidence level were finally obtained. Results: The extended uncertainty of the measurement results was 0. 19 μg · g-1 . Quercetin concentration in Sicao Tongmai capsules was (353. 65 ± 0. 19)μg·g-1 . Conclusion: The uncertainty analysis method is suitable for the standard limit formulation for Sicao Tongmai capsules, and it is important to establish uncertainty analysis methods for traditional Chinese medicines.

Objective:To verify the clinical value of the good outcome following attempted resuscitation (GO-FAR) score in predicting the neurological status of patients with in-hospital cardiac arrest (IHCA) in the Chinese population.Methods:The clinical data of patients with IHCA who were admitted to the Zigong Fourth People's Hospital from January 1 to December 31, 2020 were retrospectively analyzed. Used Glasgow-Pittsburgh cerebral performance category (CPC) score 1 point as the end point, the subjects were divided into 4 groups according to the score: ≤ 0 group, 1-8 group, 9-20 group and ≥ 21 group. Taken the group which GO-FAR score ≤ 0 as the reference group, the odds ratio ( OR) of the other three groups compared with this group was calculated. The receiver operator characteristic curve (ROC curve) was performed to evaluate the predictive value of the GO-FAR score in favorable neurological outcome. A calibration curve was drawn for the Hosmer-Lemeshow test to analyze the degree of calibration of the GO-FAR score for predicting good neurological outcome. Results:A total of 230 IHCA patients were enrolled in the study, including 130 males, aged 74 (65, 81) years old, and 23 case (10.0%) had good neurological prognosis. There were statistically significant differences in GO-FAR-related variables, including age, a normal neurological function on admitted, acute stroke, metastatic cancer, septicemia, medical noncardiac admission, hepatic insufficiency, hypotension, renal insufficiency or dialysis, respiratory insufficiency, pneumonia, etc (all P < 0.05). Taken the GO-FAR score ≤ 0 group as the reference group, the OR values of good neurological prognosis in the GO-FAR score 1-8 group were 0.54 [95% confidence interval (95% CI) was 0.17-1.53, P = 0.250], 9-20 group were 0.17 (95% CI was 0.02-0.67, P = 0.009) and ≥ 21 group were 0.25 (95% CI was 0.05-0.85, P = 0.025). The area under the ROC curve (AUC) of the GO-FAR score for predicting favorable neurological outcome in IHCA patients was 0.653 (95% CI was 0.529-0.777, P = 0.015) and there was no significant difference in Hosmer-Lemeshow test ( P = 0.311). All these suggested that there was no significant difference between the predicted value and the actual value. Conclusions:GO-FAR score can be applied to predict neurological prognosis of IHCA patients in Chinese population. It can help clinicians to predict the prognosis of cardio-pulmonary resuscitation (CPR) and propose critical recommendations in treatment for these patients or their families.
