Objective To explore the effects ofDanshen Tongluo Detoxication Decoction on the inflammatory response of rats with bone marrow stem cell (BMSC) transplantation in acute myocardial infarction (AMI); To discuss its mechanism of action.Methods The whole bone marrow adherent method was adopted for BMSCs separation and culture. The AMI model was established by closing the left anterior descending coronary artery of SD rats. After the modeling, SD rats were randomly divided into sham-operation group, model group and BMSCs group (BMSCs transplantation group),Danshen Tongluo Detoxication Decoction group, Danshen Tongluo Detoxication Decoction + BMSCs group, 10 rats in each group. BMSCs cell suspension was injected directly into the edge of the myocardial tissue infarction area; Chinese medicine or normal saline were administered for gavage. 4 weeks later, the contents of MCP-1 and sICAM-1 in each group were detected by ELISA. TLR-4 expression was measured by Western blot method, and HE staining was used to observe the myocardial tissue pathological changes.Results Compared with the model group, the contents of MCP-1 and sICAM-1 and the protein expression of TLR-4 in BMSCs group,Danshen Tongluo Detoxication Decoction group, andDanshen Tongluo Detoxication Decoction + BMSCs group decreased, Danshen Tongluo Detoxication Decoction group was better than BMSCs group (P<0.05,P<0.01), andDanshen Tongluo Detoxication Decoction + BMSCs group was better than BMSCs group andDanshen Tongluo Detoxication Decoction group(P<0.05,P<0.01).Conclusion BMSCs transplantation combined withDanshen Tongluo Detoxication Decoction can restrain the inflammatory response of AMI model rats and repair ischemic myocardium issue, which mechanism may be related to regulating TLR-4 induced inflammatory response.

OBJECTIVE:To investigate the medication safety status of Chinese patent medicines and related influence factors for residents in Guangdong province,and provide reference for better guarantee of medication safety for residents. METHODS:Questionnaires were randomly sent out among the residents in 3 cities of Guangdong province. The cognition,utilization habit and safety awareness,the ways to get the related information of Chinese patent medicines and purchase way were surveyed and ana-lyzed statistically. RESULTS:Totally 530 questionnaires were sent out and 514 valid questionnaires were collected with effective re-covery of 96.98%. There are 64.01% of respondents didn’t know the composition of Chinese patent medicines;50.39% didn’t know the contraindications of Chinese patent medicines;48.44% didn’t know the adverse drug reactions of Chinese patent medi-cines that they were using;23.47% had once broken the tablets when took them;65.18% didn’t know that the old people had less dosage than teenagers and 44.75% didn’t know that Chinese patent medicines couldn’t be taken with some western medicines. There were many ways to get the related information of Chinese patent medicines and purchase them,and the main sources were from doctors and pharmacists in drug stores;90.08% had purchased Chinese patent medicines in drug stores. CONCLUSIONS:During daily medication of Chinese patent medicines,the biggest problem for residents is that the weak awareness of medication safety,unreasonable medication behavior and habit caused by lack of related knowledge of medication safety,which may cause safety risks or happen medication safety problems. Therefore,the residents’education of self-medical knowledge should be intensi-fied,the management of prescription in drug stores should be enhanced,pharmaceutical service function of pharmacists should be played,supervision management of drug advertisement should be strengthened and the contents in drug instructions should be regu-lated.

Objective To develop a specific trans-splicing intron ribozyme type Ⅰ-mediated dual reporter gene system (Rib53-Fluc-tk) for targeting CEA.Methods The novel CEA-targeting trans-splicing ribozyme with the downstream reporter system (Rib53-Fluc-tk) was constructed by genetic engineering technology.The trans-splicing reaction product was evaluated using the 131I-5-iodo-2'-fluro-l-beta-D-arabinofuranosy-luracil (FIAU) cellular uptake rates and the bioluminescence.Two-sample t test,the analysis of variance and the least significant difference (LSD) t test was performed for data analysis.Results The sequence of Rib53-Fluc-tk was proved by gene-sequencing test.Human MCF-7 breast cancer cells showed a high ratio of firefly luciferase/renilla luciferase (0.64±0.10,n =4).A 520 bp band of product existed,which matched with the predicted size using RNA from cells transfected with Rib53-Fluc-tk in MCF-7.Signals were detected by bioluminescence in human embryonic kidney 293T cells co-transfected with Rib53-Fluc-tk and pCDNA3.1-CEA.The labelling rate of 131I-FIAU was (64.02±4.79)％ (n =3).The radiochemical purity was (95.96± 1.07)％ (n=3),and the stability of the radiocompound remained high in human serum at least for 24 h.The uptake of 131I-FIAU in 293T cells transfected with Rib53-Fluc-tk was (0.31±0.01)％ (n=4),while it increased with the incubation time in 293T cells co-transfected with pCDNA3.1-CEA and Rib53-Fluc-tk and reached (1.40±0.06)％ at 4.5 h (F=1 007.29,t=136.34,both P＜0.01).Conelusions A novel and specific reporter gene in the cellular level was established.Taking advantage of trans-splicing reaction of the ribozyme,it could improve the specificity of the reporter gene imaging.

OBJECTIVETo develop a quick identification method for the sun-dried and sulfur-fumigated Angelicae Sinensis Radix used by Fourier transform infrared spectroscopy (FTIR) combined with second derivative infrared spectroscopy.

METHODThe alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Angelicae Sinensis Radix were analyzed by using FTIR, the further analysis was used by second derivative infrared spectroscopy.

RESULTThere existed differences between their infrared spectra either extracted by ethanol or water, while the distinctions were more obvious after analyzing their alcoholic and aqueous extracts through high resolution of second derivative infrared spectroscopy. Infrared spectra showed that the absorption peaks of Angelicae Sinensis Radix were significantly reduced and a new absorption peak appeared after sulfur-fumigated process in alcoholic extracts, while both of them changed markedly in the "fingerprint region" ranging from 1 000 to 400 cm(-1) in aqueous extracts. Second derivative spectra showed that the absorption peaks of sulfur-fumigated Angelicae Sinensis Radix extracted by ethanol weakened and disappeared at about 3 578 cm(-1) and 3 541 cm(-1), while both of them differed significantly from each other ranging from 1 400 to 1 200 cm(-1) as well as 800 cm(-1) to 600 cm(-1), difference also existed between them extracted by water ranging from about 3 900 to 3 850 cm(-1) and 3 800 to 3 750 cm(-1).

CONCLUSIONThe FTIS method combined with second derivative can be utilized to distinguish sun-dried and sulfur-fumigated Angelicae Sinensis Radix efficiently, conveniently and accurately, and provide a basis for identification and quality control of Angelicae Sinensis Radix.

Objective: The purpose of our study was to investigate the predictive abilities of clinical and computed tomography (CT)features for outcome prediction in patients with coronavirus disease (COVID-19). Materials and Methods: The clinical and CT data of 238 patients with laboratory-confirmed COVID-19 in our two hospitalswere retrospectively analyzed. One hundred sixty-six patients (103 males; age 43.8 ± 12.3 years) were allocated in thetraining cohort and 72 patients (38 males; age 45.1 ± 15.8 years) from another independent hospital were assigned in thevalidation cohort. The primary composite endpoint was admission to an intensive care unit, use of mechanical ventilation, ordeath. Univariate and multivariate Cox proportional hazard analyses were performed to identify independent predictors. Anomogram was constructed based on the combination of clinical and CT features, and its prognostic performance wasexternally tested in the validation group. The predictive value of the combined model was compared with models built on theclinical and radiological attributes alone. Results: Overall, 35 infected patients (21.1%) in the training cohort and 10 patients (13.9%) in the validation cohortexperienced adverse outcomes. Underlying comorbidity (hazard ratio [HR], 3.35; 95% confidence interval [CI], 1.67–6.71;p < 0.001), lymphocyte count (HR, 0.12; 95% CI, 0.04–0.38; p < 0.001) and crazy-paving sign (HR, 2.15; 95% CI, 1.03–4.48;p = 0.042) were the independent factors. The nomogram displayed a concordance index (C-index) of 0.82 (95% CI, 0.76–0.88),and its prognostic value was confirmed in the validation cohort with a C-index of 0.89 (95% CI, 0.82–0.96). The combinedmodel provided the best performance over the clinical or radiological model (p < 0.050). Conclusion Underlying comorbidity, lymphocyte count and crazy-paving sign were independent predictors of adverseoutcomes. The prognostic nomogram based on the combination of clinical and CT features could be a useful tool for predictingadverse outcomes of patients with COVID-19.

Objective:To explore the efficacy of doctor-nurse co-led care involving education and engagement of patients on improving compliance of patients, and a treat-to-target urate-lowering rate for gout.Methods:Nurses were trained in practice management of gout. Patients diagnosed with gout in the departments of rheumatology and immunology of Anqing Municipal Hospital in Anhui Province were prospectively enrolled from January 1 to June 30, 2019. The patients were divided into the continuous-care group and the conventional management group by random number table method. The patients of continuous-care group received telephone follow-up, WeChat tracking and regular face-to-face communication. The patients of conventional management group were told to follow up regularly in the outpatient department, and the nurses did not follow up. Patients were evaluated before intervention and 12 months after intervention. The treat-to-target rate of blood uric acid and the frequency of gout flares were observed.Results:After 12 months of intervention, the patients of serum uric acid concentrations below 360 μmol/L were 92.39% (85/92) in the continuous-care group, and 26.74% (23/86) in the conventional management group. There was significant difference ( χ2 value was 80.282, P<0.001). After 12 months of intervention, the average serum uric acid concentration of patients in the continuous-care group was (301.6±61.4) μmol/L, and that in the conventional management group was (419.0±98.0) μmol/L, both of which were significantly lower than before intervention, continuous-care group (466.1±119.7) μmol/L, conventional management group (477.8±113.1) μmol/L. But the average serum uric acid concentration of patients in the continuous-care group was significantly lower than that in the conventional management group. There was significant difference between them ( t value was 96.678, P<0.001). At the end of 12 months, the patients of uric-acid-lowering therapy increased in both groups. The proportion of patients was 94.56% (87/92) in the continuous-care group, which was significantly higher than that in the conventional management group (58.14%, 50/86), there was significant difference ( χ2 value was 33.260, P<0.001). Conclusions:The mode of continuing nursing combined with specialized physician-led treatment can significantly improve the compliance and the control rate of treat-to-target for gout, and this management method is simple and feasible which provides a new management concept for clinical treatment of gout.

Objective:To explore the effect sense of security and self-control on parent-child cohesion and externalizing problem behaviors in primary and middle school students.Methods:A total of 1 402 primary and middle school students were investigated with the problem behavior frequency scale(PBFS), family adaptability and cohesion scale(FACES-CV), security questionnaire(SQ) and brief self-control scale(BSCS). SPSS 25.0 and PROCESS v2.16 were used for statistical analysis, and common method deviation test, Pearson correlation analysis and intermediary effect analysis were used in the analysis.Results:Parent-child cohesion of primary and middle school students was positively correlated with security and self-control ( r=0.279, 0.303, both P<0.01), which was negatively correlated with externalizing problem behaviors ( r=-0.154, P<0.01). Security was positively correlated with self-control ( r=0.567, P<0.01). Security, self-control and externalizing problem behaviors were negatively correlated ( r=-0.147, -0.250, both P<0.01). The security and self-control of primary and middle school students played a partial mediating role between parent-child cohesion and externalizing problem behaviors.The mediating effect consisted of two paths: one was parent-child cohesion-self-control-externalizing problem behaviors, the other was parent-child cohesion-security-self-control-externalizing problem behaviors. The effect values of these two paths accounted for 20.52% and 20.26% of the total effect respectively. Conclusion:Parent-child cohesion not only directly affects the externalizing problem behaviors of primary and middle school students, but also indirectly affects the externalizing problem behavior through the independent mediating effect of self-control and the chain mediation of security-self-control.
