Objective To explore the effect of berberine hydrochloride on serum HIF-1α,Caspase -3 levels in patients with acute cerebral infarction with a multicenter study.Methods 126 patients with acute cerebral infarction from January 2012 to January 2014 were selected in the Affiliated Hospital of Hebei Engineering University,the First Hospital of Handan City,Handan Central Hospital were divided into experimental groups and control group using random number table.Control group had 63 cases,were given 80 mg ozagrel sodium injection intravenously,twice a day,and 800 mg calf blood protein injection intravenously,once per day on the basis of conventional treatment;at the same time,100 mg of oral aspirin tablets were taken,once per night,7 days for a course of treatment.Experimental group were given berberine hydrochloride on the basis of conventional treatment,0.7 g orally,three times a day,7 days for a course of treatment.After a course of treatment,serum HIF-1α,Caspase-3 levels in patients with acute cerebral infarction were observed before and after treatment.Results Serum HIF-1αlevels in two groups were reduced after treatment,and its level in experimental group[(733.49 ±225.01)ng/mL]was lower than that in control group [(975.32 ±311.35)ng/mL],the difference was statistically significant (P<0.05 ).Serum Caspase-3 levels in two groups after treatment were decreased,and its level in experimental group [(1 1.88 ±2.66 )ng/mL]was lower than the control group [(12.51 ±3.77)ng/mL],the difference was statistically significant (P <0.05).Conclusion Berberine hydrochloride could improve the serum HIF-1α,Caspase-3 levels in patients with acute cerebral infarction,reduce the fatality rate,and could be actively used in the recovery of patients with acute cerebral infarction treatment.

Objective To quantitatively analyze total hepatitis B virus (HBV) DNA (HBV tDNA),covalently closed circular DNA (cccDNA) and HBsAg in patients with chronic hepatitis B (CHB),HBV-related liver cirrhosis (LC) and hepatocellular carcinoma (HCC),and to analyze the characteristics.Methods HBV tDNA and HBV cccDNA in the serum and liver biopsy samples were measured in 21 CHB,23 LC and 25 HCC patients by real-time polymerase chain reaction (PCR) assay. HBsAg titer was measured by chemiluminescence. Normally distributed variables among multiple groups were analyzed by ANOVA and t-test.Correlation between two variables was tested using Pearson correlation analysis.Skewed distribution was tested using Rank sum test.Results In CHB,LC and HCC patients,the serum HBV tDNA levels were (5.38±2.08),(4.96± 1.65) and (4.18 ± 0.91) lg copy/mL,respectively; the intrahepatic HBV tDNA levels in three groups were (7.18±1.91),(6.51±1.87) and (5.87± 1.47) lg copy/ug,respectively; the intrahepatic HBV cccDNA levels were (3.53±2.03),(2.63±2.13) and (0.58± 1.40) lg copy/μg,respectively; the serum HBsAg levels were (3.30±0.65),(3.12±0.52) and (2.60± 1.03) lg IU/mL,respectively.In CHB patients,the serum HBV tDNA,intrahepatic HBV tDNA,HBV cccDNA and HBsAg levels were all significantly higher than those of HCC patients (t=2.446,P=0.013; t=2.562,P=0.014;t=5.799,P＜0.01 ; t=2.709,P=0.003,respectively).However,only intrahepatic HBV cccDNA and HBsAg levels were statistically different between LC and HCC patients (t=-3.894,P＜0.01;t=-2.237,P=0.023,respectively).HBV cccDNA was all negative in the serum of 69 patients.The serum HBsAg level was positively correlated with serum HBV tDNA (r=0.290,P=0.016),intrahepatic HBV tDNA (r=0.372,P =0.002) and intrahepatic HBV cccDNA (r=0.378,P=0.001).Conclusions The levels of HBV tDNA,HBV cccDNA and HBsAg decrease gradually with the disease progression.The serum HBsAg level is positively correlated with serum HBV tDNA,intrahepatic HBV tDNA and intrahepatic HBV cccDNA.

Objective:To investigate the clinical value of continuous increase of blood lactic acid (Lac) in prognosis evaluation of patients with sepsis.Methods:From January 2016 to December 2018, 84 patients with sepsis in the Department of Critical Medicine of Lanzhou First People's Hospital were retrospectively analyzed. According to the final outcome, the patients were divided into death group and survival group. The general condition, initial Lac, Lac at 6, 12, 18, 24 h, and the duration of Lac>2 mmol/L (T Lac>2) were compared between the two groups. Receiver operating characteristic curve (ROC) was used to analyze the sensitivity and specificity of gender, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), initial lac, 6, 12, 18, 24 h lac, T Lac>2 in evaluating the prognosis of patients with sepsis. At the same time, the relationship between these parameters and the prognosis of patients was analyzed by Cox regression analysis to evaluate the clinical value of the time of continuous increase of blood lactate in the prognosis of patients with sepsis. Results:There was no significant difference in age, gender, APACHE Ⅱ score and initial lac between the two groups ( P>0.05). The Lac of death group was higher than that of survival group at 6, 12, 18 and 24 h after treatment ( P<0.05), and T Lac>2 in death group was significantly longer than that in survival group ( P<0.05). Cox regression analysis showed that age, gender, APACHE Ⅱ score, initial Lac, 6, 12, 18, 24 h lac had no significant effect on the prognosis of sepsis patients, while T Lac>2 was significantly correlated with survival rate and death risk. The longer T Lac>2 was, the lower the survival rate and the higher the risk of death. At the same time, ROC curve analysis showed that gender, age, APACHE Ⅱ score and area under the curve (AUC) of initial lac showed that these indicators could not effectively evaluate the prognosis of patients ( P>0.05). The area under the curve of T Lac>2 was the largest, and the evaluation of prognosis was the best, followed by 24 h Lac and 18 h, 12 h and 6 h Lac. In addition, the sensitivity of T Lac>2, 24, 18, 12, 6 h for sepsis mortality risk assessment were 90.9%, 81.8%, 81.8%, 81.8%, 88.6%, and the specificity were 71.4%, 52.5%, 52.5%, 47.7% and 25.2%, respectively. Conclusions:Transient increase of lactic acid can not evaluate the prognosis of patients with sepsis, but the duration of lactic acid increase has a significant impact on the prognosis of patients with sepsis. The longer the increase of Lactic acid (T Lac>2) is, the lower the survival rate and the higher the risk of death. The sensitivity and specificity of lactic acid duration in evaluating the risk of death were higher than those of other parameters, and the prognostic efficacy was the best.

Objective To observe the effect of transcutaneous electrical acupoint stimulation(TEAS)on circulation depression in patients underwent thoracoscopic radical resection of lung cancer under general anesthesia combined with thoracic paravertebral block(TPVB).Methods A total of 150 patients from Octomber 2021 to May 2022,58 males and 92 females,aged 19-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,underwent thoracoscopic radical resection of lung cancer under general anesthesia combined with TPVB were enrolled.According to random number table method,the patients were divided into two groups:the TEAS group and the control group,75 patients in each group.In the TEAS group,transcutaneous electrical acupoint stimulation was performed at Hegu,Neiguan,and Zusanli 30 minutes be-fore induction until the end of operation.In the control group,the electrodes were only connected at the same time point without electrical stimulation.HR,SBP,DBP,MAP,and BIS were recorded before stimu-lation(T0),10 minutes after TPVB(T1),the time of skin incision(T2),30 minutes after operation star-ted(T3),60 minutes after operation started(T4),the end of operation(T5),and 30 minutes after opera-tion(T6).The incidences of bradycardia,tachycardia,hypotension,and hypertension,and the usages of vasoactive drugs during operation were recorded.The dosages of propofol,sufentanil,and remifentanil in the operation were recorded.The VAS pain score 1,2,and 7 days after operation,the usages of analgesics used within 7 days after operation,postoperative adverse effects such as nausea and vomiting,dizziness,chest tightness,and shortness of breath,and the length of hospital stay were recorded.Results Compared with the control group,intraoperative infusion volume,incidence of hypotension,hypertension,and circulation depression,the usages of deoxyepinephrine,ephedrine,norepinephrine,and urapidil intraoperation,VAS pain scores 1 and 2 days after operation,and the usage of analgesics within 7 days after operation were sig-nificantly decreased(P＜0.05),length of hospital stay was significantly shortened(P＜0.05),SBP,DBP,and MAP were significantly increased at T1(P＜0.05),the dosagesof propofol,sufentanil,and remifentanil were significantly decreased in the TEAS group(P＜0.05).There were no significantly differ-ences of nausea and vomiting,dizziness,and shortness of breath between the two groups.Conclusion TEAS can improve the circulation depression,and reduce the incidences of intraoperative hypotension and hypertension,decrease the dosages of anesthetics and the rate of using vasoactive drugs during operation,improve early postoperative acute pain and shorten the length of hospital stay in patients undergoing thoraco-scopic radical resection of lung cancer under general anesthesia combined with TPVB.
