ABSTRACT
ObjectiveBy observing the effect of Qianyang Yuyin granules on the phenotype of renal tubule epithelial cells， the intervention of Qianyang Yuyin granule on renal interstitial fibrosis was investigated. MethodThe renal tubular epithelial cells （HK-2） were treated with different concentrations of transforming growth factor （TGF）-β1 （5， 10， 15， 20， 25 μg·L-1） for 24 hours， and cell morphology and growth state were observed with an inverted phase contrast microscope. The 20 μg·L-1 was selected as the most appropriate concentration of TGF-β1 according to Western blot results for subsequent experiments. HK-2 cells were divided into six groups： blank group， TGF-β1 group （concentration of 20 μg·L-1）， low， medium， and high dose Qianyang Yuyin granule groups （concentration of 0.5， 1， 2 g·L-1）， and valsartan group （1 × 10-5 mol·L-1）. The cell activity was measured by cell proliferation and cell counting kit-8 （CCK-8）. The cell migration ability was detected by scratch test. The Transwell method was used to detect the invasiveness of cells. Western blot was used to detect levels of fibronectin （FN）， E-cadherin， α-smooth muscle activator （α-SMA）， Vimentin， collagen type Ⅰ（Col Ⅰ）， collagen type Ⅳ（Col Ⅳ）， and other related proteins. ResultTGF-β1 stimulating epithelial-mesenchymal transition （EMT） in renal tubular epithelial cells was time- and concentration-dependent. Compared with the blank group， higher concentration in the TGF-β1 group indicates longer intervention time and more obvious long spindle change of cells， and the migration and invasion ability of the cells was significantly enhanced. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ increased significantly （P<0.05， P<0.01）， while the expression level of E-cadherin protein decreased （P<0.05）. Compared with the TGF-β1 group， Qianyang Yuyin granule groups could maintain normal cell morphology， and the migration and invasion ability of the cells was inhibited. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ decreased （P<0.05， P<0.01）， and the expression of E-cadherin protein was significantly restored （P<0.05）. ConclusionQianyang Yuyin granule can reverse TGF-β1-induced interstitial transformation of renal tubular epithelial cells by reducing the phenotypic expression of mesenchymal cells and increasing the phenotypic expression of epithelial cells.
ABSTRACT
Objective:To investigate the whole genome of SARS-CoV-2 causing COVID-19 in Rongcheng city of Shandong Province in May 2022 and to further analyze the nucleotide and amino acid variations for source tracing.Methods:High-throughput sequencing was used to sequence the SARS-CoV-2 genome in 15 nasopharyngeal swab samples from COVID-19 cluster infections and three environmental samples related to an aquatic product import company. Whole-genome sequence splicing, variant site analysis and sequence typing were performed on the raw sequencing data using virus sequence and variant analysis software. A phylogenetic tree was constructed by evolutionary analysis software. Epidemiological investigation was used to trace the potential source of infection.Results:Thirteen whole genome sequences of SARS-CoV-2 with the length ranging from 29 653 bp to 29 780 bp were successfully obtained from the nasopharyngeal swab samples. The average sequencing depth was 1 756-6 565 X and the genome coverage was 99.20%-99.63%. The results of Pangolin typing showed that the 13 genomes belonged to the VOC/Gamma (P.1.15) evolutionary branch. Compared with the Wuhan reference strain (NC_045512.2), the 13 genome sequences had 40-41 nucleotide mutation sites. There were 23-24 amino acid variation sites in seven protein domains (ORF1a, ORF1b, S, ORF3a, ORF8, ORF9b and N proteins). Evolutionary analysis showed that the viral sequence was grouped to the same subclade as the reference strain from Argentina (EPI_ISL_4082233).Conclusions:In this study, the whole genome sequences of 13 Gamma variant strains were obtained from COVID-19 cluster infections associated with imported cold-chain aquatic products in Rongcheng city, and the imported seafood from South America in 2021 was found to be the source of the virus in a timely manner. This study provided reference for the SARS-CoV-2 variant analysis and case tracing and also suggested that the survival and transmission ability of SARS-CoV-2 on the surface of cold-chain products should not be underestimated and needed further investigation.
ABSTRACT
Objective:To discuss the effect of Xiaoqinglong decoction on vascular endothelin (ET) in rats pulmonary hypertension (PAH) model based on the Jiebiaokuoluo method.Methods:Sixty male SD rats were randomly divided into six groups: control group, PAH model group, positive drug group, and Xiaoqinglong decoction in the high-dose, medium-dose and low-dose groups, 10 rats in each group. The control group did not receive any treatment. The remaining groups were kept in low-pressure oxygen tanks, injections of lipopolysaccharide (LPS) at 200 μL on day 1 and day 14, respectively. The rats were smoked twice a day from day 2 to day 30 (except day 14) at 4 hours intervals. The rats were placed in a low-temperature environment for 1 hour per day, and were put into cold water to swim (for 2 weeks), while the rats were given a cold diet. After modeling, the control group and the PAH model group were given equal volumes of normal saline; the positive drug group was given bosentan (100 mg/kg); Xiaoqinglong decoction 15, 10 and 5 g/kg was given, respectively, in the high, medium and low dose groups; once daily for 30 days. The mean pulmonary artery pressure (mPAP) and right ventricle systolic pressure (RVSP) were then measured with right heart catheterization and the right ventricle hypertrophy index (RVHI) was assessed; ET-1 and nitric oxide (NO) levels were determined by radioimmunoassay.Results:Compared with the control group, the levels of mPAP, RVSP, RVHI and ET-1 were significantly increased in the PAH model group [mPAP (mmHg, 1 mmHg≈0.133 kPa): 33.20±1.04 vs. 13.20±1.03, RVSP (mmHg): 62.40±1.54 vs. 24.20±1.02, RVHI: 42.90±2.51 vs. 25.40±2.01, ET-1 (ng/L): 100.80±20.34 vs. 81.50±13.84, all P < 0.05], while NO levels were significantly decreased (mmol/L: 23.20±1.81 vs. 31.70±1.49, P < 0.05). Compared with the PAH model group, the levels of mPAP, RVSP, RVHI and ET-1 in the positive drug group and high, medium, low dose groups of Xiaoqinglong decoction were significantly decreased [mPAP (mmHg): 25.50±0.84, 26.90±0.74, 27.10±1.19, 29.10±0.75 vs. 33.20±1.04, RVSP (mmHg): 54.40±5.14, 50.10±1.67, 53.10±1.05, 56.60±1.07 vs. 62.40±1.54, RVHI: 41.10±1.19, 31.20±1.67, 31.30±1.89, 40.30±1.88 vs. 42.90±2.51, ET-1 (ng/L): 70.70±7.89, 69.90±2.92, 71.70±4.32, 73.90±5.19 vs. 100.80±20.34, all P < 0.05], while NO levels were significantly increased (mmol/L: 32.50±2.06, 34.70±1.16, 32.70±1.33, 30.10±1.19 vs. 23.20±1.81, all P < 0.05), and with the increased dose of Xiaoqinglong decoction, the change was more obvious, and the effect was better in the high-dose group. Conclusion:Xiaoqinglong decoction can reduce rats PAH by regulating ET-1 and NO levels in a dose-dependent manner.

ABSTRACT
Objective To study the effects of Qingzao Runfei Huazhuo Xingxue decoction (QRHXD) on inflammatory reaction and histopathology in mice with PM2.5-induced pulmonary injury, and to approach the possible mechanism of prevention and treatment of traditional Chinese medicine on lung injury induced by haze.Methods Fifty healthy male C57BL/6 mice were randomly divided into five groups (n = 10): namely control, PM2.5, PM2.5+ low-, moderate-, and high-dose groups. The PM2.5 suspensions at a dosage of 40 mg/kg was respectively given to mice by the nasal instillation for reproduction of mouse model of lung injury induced by PM2.5, and the mice in control group were given the same volume of normal saline. The mice in PM2.5+ low-, moderate-, and high-dose QRHXD groups were given 15, 25, 50 mL·kg-1·d-1 QRHXD by oral perfusion daily for consecutive 21 days at the next day of model reproduction (the QRHXD included: Pear 75 g,Bulbus Fritillariae Cirrhosae 10 g, Radix Stemonae 8 g,Rhizoma Pinelliae 8 g,Radix Platycodi 6 g, Aster 10 g, Almond 5 g, Lily 6 g, Rhodiola 4 g, Lotus 3 g,Fructrs Liquidambaris 6 g,Radix Paeoniae Rubra 5 g, Semen Cassiae 6 g). The mice in control and PM2.5 groups were given equivalent volume of normal saline respectively. After treatment for 21 days, the mice were sacrificed, and the left lung was harvested for bronchoalveolar lavage, and the bronchoalveolar lavage fluid (BALF) was collected for determination of levels of acid phosphatase (ACP), alkaline phosphatase (AKP), lactic dehydrogenase (LDH), and albumin (ALB). The right lung was harvested for histopathology observation under light microscope using hematoxylin and eosine (HE) staining.Results After intranasal instillation of PM2.5 suspension, the levels of ACP, AKP, LDH, and ALB in PM2.5 group were significantly higher than those in control group [ACP (U/L): 3.9±0.4 vs. 1.7±0.3, AKP (U/L): 9.0±1.5 vs. 4.8±0.3, LDH (U/L): 416.7±44.4 vs. 112.5±20.3, ALB (mg/L): 198.7±32.4 vs. 65.8±21.3, all P < 0.05]. Under light microscope, the PM2.5 particles were collected, the alveolar septa were thickened, and the inflammatory cells in the alveolar cavity and pulmonary interstitium were found. On the contrary, after administration of QRHXD, a significant reduction of biochemical indexes was found, which showed a dose-dependent manner. The parameters of PM2.5+ high-dose QRHXD group were significantly lower than those in PM2.5 group [ACP (U/L): 2.1±0.8 vs. 3.9±0.4, AKP (U/L): 5.3±1.4 vs. 9.0±1.5, LDH (U/L): 146.6±29.8 vs. 416.7±44.4, ALB (mg/L): 88.5±26.7 vs. 198.7±32.4, all P < 0.05]. At the same time, the pathological changes in lung tissue were better with the increase of the dose.Conclusions QRHXD can reduce the pulmonary inflammatory response and tissue damage caused by PM2.5, with the increase concentration of Chinese medicine, and the effect is more obvious. This may be related to the immune response of the human body to regulate inflammatory mediators, which provide basis for the treatment of pulmonary injury induced by PM2.5.

METH-ODS:The data of online drugstores with top 20 approvals data and sales amount were collected bu the Internet,the normative man-agement was evaluated. Meanwhile,questionnaire was conducted to survey and analyze the cognition,buying drugs and correspond-ing requirements of some Shanghai citizens for Internet drug retail. RESULTS:By Jun. 12,2015,totally 307 retail chain drug-stores(online drugstores)had got the License of Internet Drugs Transaction,only 62 online drugstores(20.2%)were in full compli-ance with the normative management;the top 19 online drugstores supplied averagely 1 072±815 OTC medicines,including 259± 165 chemical drugs and 813 ± 650 Chinese traditional medicines,and the top 3 were jianke.com (3 658 species),J1.com (2 071 species)and 360 kad.com(1 523 species). Totally 216 questionnaires were sent out,and 183 were effectively received with effec-tive recovery of 84.7%. The 183 surveyed citizens showed high cognition in distinguishing the authenticity of online drugstores (75.4%) and the authenticity of drugs (67.1%),but low cognition in online drugstore opening qualifications and Internet selling drugs;only 22.4% had the experience of buying drugs online,the degree of satisfaction towards online shopping,from the highest to the lowest,were drug price(62.5%),professional consultation of pharmacists(50.0%),variety of drugs(45.0%),quality of drugs(37.5%),delivery time(35.0%),etc.;the most probably purchased medicine category were vitamins and minerals(63.9%) and medicines for common diseases(40.4%). CONCLUSIONS:Currently the demands and confidence of online drugs shopping of Shanghai citizens are still scarce. Though the access of retailing prescription drugs would spur the Internet drug business,the condi-tion is still immature. It is suggested to sell prescription drugs in a limited way and improve their access threshold,promote Medi-care settlement to multi-faceted promote the orderly development of Internet drug transaction services.
ABSTRACT
Objective To study the influence of Qingzao Runfei Huazhuo Xingxue decoction on pulmonary tissue and lung function in mouse model of lung injury induced by PM2.5, and to provide an idea of clinical prevention and treatment of respiratory diseases induced by PM2.5. Methods Totally 30 clean level male ICR mice were randomly divided into three groups: normal control group, model group and Qingzao Runfei Huazhuo Xingxue decoction intervention group, with 10 mice in each group. Model of PM2.5-induced respiratory disease in mice was reproduced by instilling nasal cavity drip PM2.5 suspension 40 mg/kg once a day for 6 weeks. In the treatment group, the mice were fed with the Qingzao Runfei Huazhuo Xingxue decoction twice a day from the 4th week of instilling PM2.5 suspension until the end of experiment. In the normal control group, the mice were fed as usual. At the end of the experiment, the total protein content in bronchoalveolar lavage fluid (BALF), and lung wet/dry weight (W/D) ratio was determined. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in lung tissue under light microscope. The inflammatory mediators levels in lung tissue were determined by antibody-sandwich enzyme linked immunosorbent assay (ELISA).

Objective To investigate the effects of early continuous renal replacement thempy(CRRT)on correlation kidney injury and prognosis in patients with severe acute pancreatitis(SAP).Methods According to the digital table,40 SAP patients were randomly divided into two groups:the control group(21 cases)and CRRT treat-ment group(19 cases).The levels of serum creatinine,urea nitrogen,IL -1,IL -6,TNF -α,the APACHEⅡscore, the incidence of mechanical ventilation were compared between the two groups.Results The levels of serum creati-nine,urea nitrogen were significantly lower in the CRRT group than those in the control group in day 3(t =2.836, 2.952,P =0.003,0.004);The levers of IL -1,IL -6,TNF -αwere significantly lower in the CRRT group than those in the control group in day 3(t =2.376,2.414,2.197,P =0.351,0.028,0.042);The APACHE II score,inci-dence of mechanical ventilation,the fatality rate in the CRRT group were significantly lower than those in the control group in day 3[(20.16 ±5.23)points vs.(13.83 ±4.48)points,14 cases(66.7%)vs.6 cases(31.6%),8 cases (38.1%)vs.2 cases(14.3%),t =4.572,χ2 =4.912,4.043;P =0.0329,0.027,0.044].Conclusion Early CRRT therapy can eliminate the IL -1,IL -6 and TNF -αin SAP patients,can reduce the incidences of AKI,which may provide more clinical benefits in the early phase of SAP.
ABSTRACT
Objective To explore the effects of continuous renal replacement thempy ( CRRT) on efficacy in severe acute pancreatitis ( SAP) patients based on different time .Methods A total of 38 SAP patients were divided into two groups randomly:early group(CRRT within 48h) for 21 patients and late group(CRRT after 48h)for 17 pa-tients.the APACHE II score,the length of stay ICU and the mortality of 28d were compared between the two groups . Results The APACHE Ⅱscore was significantly higher in late group than that in early group in day 1 and 2 ( t=2.231,2.304,both P0.05);the hospitalizing days and mortality were significantly higher in late group than that in early group(t=2.156,χ2 =4.293,both P0.05).Conclusion Early CRRT can decrease both the hospi-talizing days and mortality in SAP patients .CRRT may provide more clinical benefits in the early phase (within 48h) of SAP.
ABSTRACT
Objective To investigate the clinical efficacy of application of differentiation of traditional Chinese medicine(TCM)syndrome and rectal administration of TCM decoction for treatment of patients with non-small cell lung cancer(NSCLC)and its influence on chemotherapy toxic side effects. Methods Seventy-two patients with NSCLC were randomly divided into two groups:the chemotherapy alone group and rectal administration group(each 36 cases). Both groups received chemotherapy,and the rectal administration group additionally took the rectal administration of self made Kangfei Sanjie decoction(composition:ephedra 6 g,forsythia 20 g,citrus aurantium 20 g,platycodon root 10 g,almonds 10 g,rhubarb charcoal 6 g,scutellariae barbatae 30 g,hedyotic diffusa 30 g,actinidiae 15 g, fritillariae thunbergii 10 g,angelica 10 g,asarum 3 g,mirabilitum depuratum 6 g),and according to the patient's individual situation,the ingredients of the decoction could be added or subtracted to perform pulverization enema, once a day,21 days constituting one therapeutic course. After two cycles of chemotherapy,the changes of tumor lesions,KPS score and the occurrence and degree of chemotherapy adverse reaction were observed. Results The total therapeutic efficiency of rectal administration group was higher than that of chemotherapy alone group,but there was no significant difference between them(63.89% vs. 55.56%,P>0.05);the KPS score of rectal administration group was apparently higher than that of chemotherapy alone group(89.52±10.25 vs. 83.17±8.08,P0.05). Conclusion Application of TCM differentiation of syndrome and rectal administration of TCM drug, Kangfei Sanjie decoction,can significantly improve the quality of life of NSCLC patients,reduce toxic side effects of chemotherapy,and the method is simple and inexpensive.
ABSTRACT
Objective To investigate the effects of the serum from rats with hemorrhagic shock and Shenfu injection, on the expression of endothelial cell protein C receptor (EPCR) in human umbilical vein endothelial cells (HUVECs) cultured with rat serum. Method The soluble endothelial protein C receptor (sEPCR) in supernatant, the expression of EPCR mRNA and protein level of EPCR in HUVECs were detected by using enzyme linked immunosorbent assay ( ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western bloting (WB) in normal control group, hemorrhagic shock serum (3 h, 12 h, 24h, 72 h) group, and Shenfu-treated (3 h, 12 h, 24 h, 72 h) group, respectively. Results The mean levels of sEPCR and the expression of EPCR mRNA were significantly higher in hemorrhagic shock serum (12 h, 24 h) group, and Shenfu -treated(24 h)group than those in normal control group (all P ＜0.01 ),the mean levels of sEPCR and the expressions of EPCR mRNA were significantly higher in Shenfu-treated ( 12 h) group than those in normal control group ( all P ＜0. 05 ), while the levels of protein were lower in hemorrhagic shock serum ( 12 h, 24 h) group and in Shenfu-treated(24 h)group than those in normal control group ( both P ＜0.01 ), and the level of EPCR protein was lower in Shenfu-treated( 12 h) group than that in normal control group ( P ＜ 0. 05) . The mean levels of sEPCR and the expressions of EPCR mRNA were significantly lower in Shenfu-treated ( 12 h, 24 h) group than those in hemorrhagic shock serum ( 12 h,24 h) group (all P ＜0.05), while the levels of EPCR protein were higher in Shenfu-treated ( 12 h, 24 h)group than those in hemorrhagic shock serum ( 12 h, 24 h) group ( P ＜ 0.05 ). Conclusions These data suggest that Shenfu injectio could affect the expression of EPCR mRNA and the level of EPCR protein, thereby it might be effective in prevention of development of hemorrhagic shock.
