OBJECTIVES: To develop a new Chinese medicine (CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome (ARDS) in COVID-19 patients. METHODS: A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized, controlled two-arm trial. The two arms of the trial consist of a control therapy (alpha interferon inhalation, 50 µg twice daily; and lopinavir/ritonavir, 400 and 100 mg twice daily, respectively) and a testing therapy (control therapy plus Keguan-1 19.4 g twice daily) by random number table at 1:1 ratio with 24 cases each group. After 2-week treatment, adverse events, time to fever resolution, ARDS development, and lung injury on newly diagnosed COVID-19 patients were assessed. RESULTS: An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events. Based on this result, the study was expanded to include a total of 48 participants (24 cases each arm). The results show that compared with the control arm, the testing arm exhibited a significant improvement in time to fever resolution (P=0.035), and a significant reduction in the development of ARDS (P=0.048). CONCLUSIONS Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.

Objective To predict the monthly reported echinococcosis cases in China with the autoregressive integrated mov-ing average(ARIMA)model,so as to provide a reference for prevention and control of echinococcosis. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported echinococcosis cases of time series from 2007 to 2015 and 2007 to 2014,respectively,and the accuracies of the two ARIMA models were compared. Results The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2015 was ARIMA(1,0,0)(1,1, 0)12,the relative error among reported cases and predicted cases was-13.97%,AR(1)=0.367(t=3.816,P<0.001),SAR (1)=-0.328(t=-3.361,P=0.001),and Ljung-Box Q=14.119(df=16,P=0.590).The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2014 was ARIMA(1,0,0)(1,0,1)12,the relative error among reported cases and predicted cases was 0.56%,AR(1)=0.413(t=4.244,P<0.001),SAR(1)=0.809(t=9.584, P<0.001),SMA(1)=0.356(t=2.278,P=0.025),and Ljung-Box Q=18.924(df=15,P=0.217).Conclusions The different time series may have different ARIMA models as for the same infectious diseases.It is needed to be further verified that the more data are accumulated,the shorter time of predication is,and the smaller the average of the relative error is.The estab-lishment and prediction of an ARIMA model is a dynamic process that needs to be adjusted and optimized continuously accord-ing to the accumulated data,meantime,we should give full consideration to the intensity of the work related to infectious diseas-es reported(such as disease census and special investigation).

Dietary pattern has been revealed to be associated with metabolic syndrome. However, the association was not well documented in Chinese due to the complexity of Chinese foods. We mainly assessed the dietary patterns and examined their effects on metabolic syndrome among Chinese adults. Four dietary patterns including 'Refined Grains & Vegetables' Pattern, 'Dairy & Eggs' Pattern, 'Organ Meat & Poultry' Pattern, and 'Coarse Grains & Beans' Pattern were extracted. 'Dairy & Eggs' Pattern was associated with a decreased odds of metabolic syndrome in women, and 'Coarse Grains & Beans' Pattern was associated with a decreased odds of hypertension in men. These results provided a scientific basis for future research and dietary guideline perfection.

Objective To evaluate the application of “OmniView”, a new three-dimensional ultrasound technology, in displaying the fetal palate. Methods The three-dimensional volume data was acquired from 100 normal fetuses, analysed by OmniView technology with the facial midsagittal plane as the starting plane. The imaging of fetal palate was obtained in axial plane (through maxilla, oral cleft), coronal plane, oblique coronal plane (through piriform aperture, oral cleft, submental triangle), and the palate′s curved plane tiled imaging by drawing the anatomical lines on referenced sagittal plane (facial midsagittal plane). The volumes of ifve fetuses with cleft lip and palate were obtained and analysed by the same technology. Results The volume dataset of 91 (91.0%, 91/100) normal fetuses were acquired successfully, and analyzed by OmniView technology, the results of 91 normal fetal palate in different plane were: (1) In axial plane through maxilla, the visualization of alveolar process bow was 91 (100%, 91/91). It was shown as“C”shaped arcuate structure, the anechoic structure of alveolar socket could be seen on the bow, and the ifrst 6 alveolar sockets were displayed clearly. The visualization number of hard palate was 91 (100%, 91/91), it was shown as hyperechoic lfake between two sides of alveolar bones. In axial plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91), it was shown as a strip of soft tissue echo band. (2) In coronal plane, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a strip of hyperechoic band and separated the oral and nasal cavity. (3) In oblique coronal plane through piriform aperture, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a short strip of hyperechoic band. In oblique coronal plane through oral cleft, the visualization number of hard palate was 91 (100%, 91/91). In oblique coronal plane through submental triangle, the visualization number of hard palate was 91 (100%, 91/91). In the above two planes, the hard palate was shown as a strip of hyperechoic band, due to acoustic shadow behind the hard palate, the nasal cavity and nasal septum above the hard palate couldn’t be displayed. (4) In oblique coronal plane through piriform aperture, the visualization number of soft palate was 81 (89.0%, 81/91). The visualization number of uvula was 25 (27.5%, 25/91). The soft palate was shown as a lfake of soft tissue echo behind the hard palate, and the uvula was shown as papillary protrusions on the edge of the soft palate in the midline. In oblique coronal plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91). In oblique coronal plane through submental triangle, the visualization number of soft palate was 81 (89.0%, 81/91). In the above two planes, the soft palate was shown as a strip of soft tissue echo band, the soft tissue echo of fetal tongue was in the lower front of soft palate, and the anechoic region of nasopharynx was superior behind the soft palate. (5) In the curved plane tiled imaging of palate, the visualization number of alveolar process bow (primary palate) was 91 (100%, 91/91). The visualization number of hard palate was 91 (100%, 91/91). The visualization number of soft palate was 81 (89.0%, 81/91). the visualization number of uvula was 25 (27.5%, 25/91), the planar panorama of alveolar process bow, hard palate and soft palate could be visualized intuitively, the alveolar arch and hard palate were shown as bone-like hyperecho, and the soft palate was shown as soft tissue hypoecho. In iffteen cases′volume involved cleft lip and palate, all five cases of malformations were detected through three-dimensional data analysis, the position and range of the cleft palate could also be conifrm. Abnormal fetuses were all veriifed after induction of labor. Conclusions By three-dimensional ultrasound technology-“OmniView”, the axial and coronal plane of fetal palate could be obtained easily which was dififcult by two-dimensional ultrasound, and the special oblique coronal plane of secondary palate could be displayed easily. The panorama of the palate could be visualized intuitively though curved plane tiled imaging by drawing a line tracking the structure of the palate. This technology could simplify the ultrasound examination procedure of the fetal palate, reduce the operators′skill-dependence, and quickly evaluated the integrity of the fetal primary palate and secondary palate. For the cleft lip fetus, this technology can determine whether the cleft palate exist or not, together with their position and range.

Objective To explore the clinical data,muscle pathological findings and recent follow-up results of 5 patients being diagnosed as having mitochondrial encephalopathy,lactic acidosis,and stroke-like episodes (MELAS).Methods A retrospective analysis was carried out on the clinical manifestations,sero-enzymology,electrophysiology,iconography and muscle biopsy pathology,and recent follow-up results of 5 patients with MELAS,who admitted to our hospital from December 2008 to June 2011.Results Headache as first symptom appeared in 3 patients,hemiparesis as first symptom in 1 patient and upper gastrointestinal bleeding in 1.The total body seizure in the course was noted in 4 patients and psychiatric symptoms in 2.The creatine kinase level was normal in 4 with one being mildly elevated.Four patients were observed no abnormal electromyography with one having myogenic lesions.Brain MRI showed significant abnormality in 5 patients,mainly presented as permanent cerebral infarction and cerebral atrophy.Five patients were found strongly SDH-reactive blood vessels (SSVs) in muscle tissue pathological staining and the SSVs of CCO (+).After mitochondrial protection treatment,follow-up for six months showed that 3 patients has been restored to normal work and mildly improvement was noted 2 patients.Conclusion The brain MR imaging of 5 patients with MELAS is significantly abnormal,and muscle biopsy pathology and tissue enzymatic staining are important methods in diagnosing the disease; generally,the disease is a benign course.

OBJECTIVETo study the effect of tanshinone II A on the cell signal transduction system protein kinase B (Akt) in rats with hypertrophy of the myocardium induced by partial constriction of the thoracic aorta.

METHODSRat models of myocardial hypertrophy were established by the thoracic aorta partial constriction method. Forty-eight rats were randomly divided into the sham-operative group, the model group, the valsartan treatment group, and the low-, medium-, and high-dose tanshinone treatment groups. The heart mass index (HMI), left ventricular mass index (LVMI), ejection fraction (EF), left ventricular posterior wall (LVPW), and interventricular septal thickness (IVS) were detected by high-frequency ultrasonography. The myocardial fiber diameter (MFD) was detected by HE staining, and the contents of p-Akt and p-Gsk3beta in the myocardium were detected by Western blot.

RESULTSCompared with the sham-operative group, the levels of HMI, LVMI, LVPW, IVS, and MFD were increased respectively in the other groups (P<0.05); the contents of p-Akt and p-Gsk3beta were also increased in the other groups. Compared with the model group, the levels of HMI, LVMI, LVPW, IVS, and MFD were decreased respectively in all treatment groups (P<0.05); the contents of p-Akt and p-Gsk3beta were decreased in all treatment groups as well. There was no significant difference, however, among the low-, medium-, and high-dose tanshinone treatment groups and the valsartan treatment group (P>0.05).

CONCLUSIONTanshinone II A can prevent myocardial hypertrophy by its action on the protein kinase B (Akt) signaling pathway.

Objective Contrast induced acute kidney injury (CIAKI) is a significant clinical problem. We, therefore, performed a prospective, randomized trial to investigate the role of probueol in the prevention of CIAKI in patients with unstable angina pectoris (UAP) undergoing percutaneous coronary angiography (CAG) and interventions (PCI). Methods We studied 205 patients with UAP, who underwent CAG or PCI prospectively. Patients were randomly assigned to probucol group (n = 102) and control group (n= 103). In the probucol group, the patients received probucol tablets 500 mg b. i. d for 3 days before and after intervcntion. All the patients, after intervention, underwent hydration with intravenous saline at a rate of 1 ml per kilogram of body weight per hour for 12 hours. Results Patients were well-matched with no significant differenced at baseline in majority measured parameters between two groups. CIAKI occurred in 23 of the 205 (11.22%) patients. Multivariate logistic regression was used to identify correlates of CIAKI and clinical data. CIAKI was most strongly associated with Scr≥132.6 μmol/L (OR =21.11,95% CI 1.95-56. 06, P＜0.001), Ccr ＜60 ml/min (OR =4.19, 95%(2/1.94-9.05, P ＜0.001), heart function ＞ class Ⅱ (OR = 6.23, 95% CI 2.73-14.21, P ＜ 0.001), Diabetes (OR = 2.049, 95% CI1.19-5.25, P ＜ 0.001), age ≥ 70 yrs (OR = 3.52, 95% CI 1.66-7.43, P ＜ 0.001), coronary artery calcification shown by CAG (OR =4.29, 95% CI 1.99-9.24, P ＜ 0.001). The rate of CIAKI in probueol groups was slightly lower compared with control group (7.84% vs. 14.56%), without significant difference. The post-procedure mean peak of Scr [(101.62±42. 98) μmol/L vs. (117.67 ～68.77) μmol/L, P =0.047] and the post-procedure increasing Ser from baseline (ASer) [(13.49 ± 19. 61) μmoL/L vs.(22.50 ± 18.31) μmol/L, P =0.001] in the probucol group decreased significantly compared with that of control group. Conclusion Prophylactic treatment with probueol 500 mg b. i. d during periproeedural stage in patients with UAP has preventing role against CIAK1 after cardiac catheterization.
