Aim To observe the anti-hepatitis B virus effect of total phenolics acid extracted from Oenanthe Javanica(OJTPA) with in vitro experiments.Methods HePG2 2.2.15 cells were treated with OJTPA,which were diluted into 500 mg?L-1,250 mg?L-1 and 125 mg?L-1 groups.The test set up positive control group(entecavir,3 mg?L-1) and normal control group.The cells of the 4 th,8 th and 4 th day ceasing treatment were collected.The content of HBV-DNA and cccDNA was determined with Quantitative Real-Time PCR method,and the inhibition rates were calculated.Results OJTPA could obviously inhibit HBV-DNA and cccDNA under the dosages used in the experiment,and showed a dose-dependent relationship.The inbhibitory rates reached the peak of 62.3% and 62.7% for HBV-DNA and cccDNA respectively,and a high inhibitory rate was retained within 3 days of OJTPA withdrawal.Conclusion OJTPA has significant inhibition on HBV-DNA and cccDNA and there is no significant rebound phenomenon.

Objective To study the dynamic changes of plasma C-reactive protein (CRP) and cortisol (COR) and their clinical value in prognosis of patients with sepsis. Methods Daily CRP and COR detection was conducted to record the dynamic changes of CRP and COR for cases of sepsis patients in ICU then the rela-tionship between dynamic changes of serum CRP and COR and prognosis were analyzed. Results Serum CRP and COR levels of dead patients were significantly higher than those of survival patients after treatment (P <0.05). According to the difference of the dynamic changes of CRP and COR, the data were divided into typeⅠ:sustained elevated type , typeⅡ: up-and-down type , type Ⅲ: fluctuated type and type Ⅳ: normal or mild ele-vation type. The mortality of CRP typeⅠ patients was significantly higher than that of type Ⅱ and type Ⅳ(P <0.001). The mortality of COR typeⅠ and COR Ⅲ patients was significantly higher than that in COR Ⅱand COR Ⅳ (P < 0.001). Further analysis showed that the mortality of group with significant elevation of CRP and COR were obviously higher than that of group with significant increase of CRP or COR and that of group with no significant elevation of CRP and COR (P < 0.001); the mortality of group with significant increase of CRP or COR was also significantly higher than that of group with no significant elevation of CRP and COR (P < 0.001). Conclusions The dynamic changes of COR and CRP in patients with sepsis present certain regularity and monitor-ing the dynamic changes of the two provides accurate assessment of the prognosis of sepsis.

The aim of this study is to investigate the effects and mechanism of extract of Apocynum venetum (AV) on kidneys of streptozotocin-induced diabetic rats. Diabetes mellitus (DM) was induced in rats by intraperitoneal injection of streptozotocin (STZ). The indexes of the blood glucose, renal function and oxidative stress were observed. The DM rats were administrated with the AV for 8 weeks, the above-mentioned indexes were detected. The blood glucose level, BUN, 24 h urine protein excretion, urine volume, renal index, renal cortex's MDA level in model groups all increased significantly. Renal cortex's SOD and GSH activities decreased significantly compared with the normal control group (P < 0.05). The above-mentioned indexes were significantly improved by the AV treatment (P < 0.05). AV have protective effects on renal function of kidneys of streptozotocin-induced diabetic rats, and maybe via inhibition of the renal oxidative stress.

Objective:To detect the factors related to hemocytopenia and interstitial lung disease (ILD) secondary to primary Sj?gren's syndrome (pSS) in in-patients.Methods:Clinical characteristics of patients with pSS hospitalized in China-Japan Friendship Hospital from March 2014 to October 2020 were retrospectively analyzed. Patients were divided into different groups according to hemocytopenia and ILD. Chi-square test and Mann-Whitney U test were used to compare data in subgroups, and logistic regression were used to detect factors related to hemocytopenia and ILD secondary to pSS. Results:Five hundred and seventy-one inpatients with pSS were included in this study and the female: male ratio was 8∶1. Two hundred and seventy five of included patients had hemocytopenia (48.2%) and 180 patients had ILD (31.5%). Compared with patients without hemocytopenia, patients with hemocytopenia had higher ratio in low C3 [ OR=2.326, 95% CI(1.483, 3.650), P<0.01] and elevation of erythrocyte sedimentation rate (ESR) [ OR=1.912, 95% CI(1.233, 2.964), PP<0.01) . Compared with patients without ILD, patients with ILD showed higher ratio in male[ OR=2.509, 95% CI(1.269, 4.959), P<0.01) and fatigue [ OR=5.190, 95% CI(5.190, 13.931), P<0.01) , lower positive rate of anti-SSA antibody [ OR=0.392, 95% CI(0.230, 0.668), P<0.01) and anti-CENPB [ OR=0.337, 95% CI(0.145, 0.782), P<0.01] antibodies, and lower ratio in low C3[ OR=0.332, 95% CI(0.189, 0.582), P<0.01]. Conclusion:Low C3 and high ESR may be risk factors for developing hemocytopenia in patients with pSS. Men with pSS may be susceptible to ILD, while pSS patients with ILD may have lower ratio in positive anti-SSA antibody, positive anti-CENPB antibody and low C3. All of these findings are yet to be validated by future prospective cohort studies.

Objective To observe the clinical effect of monosialotetrahexosyl ganglioside sodium injection (GM1) on spastic cerebral palsy. Methods 98 children with spastic cerebral palsy were randomly divided into control group (n=50) and treatment group (n=48). Both groups received Bobath approach, and the treatment group received GM1 in addition. They were assessed with Functional Independence Measure for Children (WeeFIM), Gross Motor Function Measure (GMFM) and Gesell Development Schedule (GDS) before and after 90 days of treatment. Results The scores of WeeFIM, all the dimensions of GMFM and the gross motor, fine motor, personal-social and adaption of the GDS improved in both groups after treatment (P<0.05), and improved more in the treatment group than in the control group (P< 0.05). Conclusion GM1 may further improve the recovery of function for children with spastic cerebral palsy.

Conclusion:Women with pSS present a higher ratio in dry mouth, dry eyes, leukocytopenia and positive autoantibodies than men, while parotid enlargement and ILD are more common in men than women. Young patients are prone to renal involvement, middle-aged patients are prone to arthralgia, while elderly patients are prone to dental caries and xerophthalmia. With the growth of age, the positive rates of autoantibodies and elevated IgG are decreased gradually in patients with pSS, but the ratios of dental caries, xerophthalmia and ILD is increased gradually.

Objective:To investigate the correlation of lung ultrasound score and poor prognosis in internal shock patients in intensive care unit (ICU).Methods:The clinical data of 200 shock patients admitted to the ICU of Wuzhou Red Cross Hospital from July 2019 to June 2021 were selected for study. According to the prognosis of patients, they were divided into survival group and death group. The clinical data of shock patients in ICU with different prognosis were analyzed by single factor analysis, multiple factor regression analysis and predictive value analysis.Results:All patients were followed up. The end point of the study was death or transfer from ICU. The follow-up period was 28 days, with a median of 16 days. The 28-day survival rate (OS) of all patients was 62.5%(125/200). The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, prothrombin time (PT), Fbg, D-dimer(D-D), lactic acid, oxygenation index and lung ultrasound score of the patients in the survival group and the death group were significantly different (all P<0.05), while other indexes were not significantly different (all P>0.05). The results of COX multivariate analysis showed that APACHE Ⅱ score, lactate, and lung ultrasound score were independent prognostic factors of shock patients in ICU (all P<0.05). The survival curves of patients with different lung ultrasound scores were significantly different ( P<0.05). The higher the lung ultrasound score, the lower the 28-day survival rate ( P<0.05). The receiver operating characteristic(ROC) curve analysis showed that the area under curve (AUC), sensitivity and specificity of predicting the prognosis of patients with lung ultrasound score were 0.753, 76.0% and 71.2%, respectively; The AUC , sensitivity and specificity of APACHE Ⅱ score were 0.774, 77.3% and 79.2% respectively; The AUC, sensitivity and specificity of lactic acid were 0.783, 81.3% and 68.8% respectively, with no significant difference (all P>0.05). Conclusions:The lung ultrasound score , lactic acid and APACHE Ⅱ scores are independent risk factors affecting the prognosis of ICU shock patients, and have considerable predictive value.

Objective: To investigate the effects of cigarette smoking in different manners on acute lung injury in rats .Methods: The commercially available cigarettes with tar of 1,5, 11 mg were smoked in Canada depth smoking ( health canada method , HCM) manner , and those with tar of 11 mg were also smoked in international standard ( ISO) smoking manner .Rats were fixed and exposed to mainstream in a manner of nose-mouth exposure .After 28 days, the bronchoalveolar lavage fluids from left lung were collected for counting and classification of inflammatory cells and determination of pro -inflammatory cytokines IL-1βand TNF-α.The right lungs were subjected to histological examination and determination of myeloperoxidase ( MPO ) and superoxide dismutase (SOD) activities and glutathione , reactive oxygen species (ROS) and malondialdehyde (MDA) levels.Results:In both HCM and ISO manners , the degree of lung injury was closely related to the tar content of cigarettes , and significant decrease in the body weight of rats was observed after smoking for one week .In a HCM manner , smoking with cigarette of 11 mg tar resulted in robust infiltration of macrophages , lymphocytes and neutrophils into lungs , significant increase in IL-1βand TNF-αlevels and MPO activities , and significant decrease in GSH levels and SOD activities and increase in ROS and MDA levels ( all P <0.05 ) .Smoking with cigarette of 5 mg tar led to moderate increase in IL-1βand TNF-αlevels, and MPO activities (all P<0.05), and moderate decrease in GSH levels and SOD activities and increase of ROS and MDA levels ( all P<0.05).However, smoking with cigarette of 1 mg tar affected neither inflammatory cell infiltration nor IL-1βand TNF-αlevels.Conclusion: Cigarette smoking in nose-mouth exposure manner can induce acute lung injury in rats; and the degree of lung injury is closely related to the content of tar and other hazards in cigarettes .

Objective To explore the effects of modulating the Hippo-YAP/TAZ pathway using Huashi Runzao Prescription(HRP)on the apoptosis and salivary secretion function of submandibular gland cells in a naive non-obese diabetic(NOD/Ltj)mouse model of Sj?gren's syndrome(SS).Methods Eight-week-old female BALB/c mice were selected as the blank group.Eight-week-old female NOD/Ltj were randomly divided into the model,HRP-L,HRP-M,HRP-H,and hydroxychloroquine sulphate(HCQ)groups.After eight weeks of drug administration,the water consumption and salivary flow rate of each group were recorded.The histopathological damage of the submandibular gland in each group was determined using hematoxylin and eosin staining,the apoptosis rate of the submandibular gland was determined using TUNEL staining,and AQP5,Bax,Bcl-2,beclin-1,YAP,p-YAP,and TAZ expressions in submandibular gland tissues were determined using immunohistochemistry and Western blotting.Results Compared with the blank group,the Hippo-YAP/TAZ pathway was inhibited in the submandibular gland tissues of the model group,lymphocyte infiltration increased,water consumption increased,salivary flow rate decreased,AQP5 expression decreased,and submandibular gland cells apoptosis rate increased(P<0.05).Compared with all other administered groups,in the HRP-M group,the Hippo-YAZ/TAZ pathway was significantly activated,lymphocyte infiltration in submandibular gland tissues was reduced,water consumption was reduced,the salivary flow rate and AQP5 expression were increased,and the apoptosis rate of submandibular gland cells was reduced(P<0.05).Conclusion HRP reduced the pathological damage and apoptosis of submandibular gland cells in SS model mice.It improved the overall secretory function of submandibular gland tissues,which may be related to Hippo pathway activation and downregulating YAP/TAZ expression.
