OBJECTIVETo observe the efficacy differences among acupuncture at Neiguan (PC 6) and Zusanli (ST 36), dolantin and scopolamine in treatment of acute renal colic, and to verify the clinical effect of acupuncture at Neiguan (PC 6) and Zusanli (ST 36).

METHODSTwo hundred and forty patients were randomly divided into an acupuncture group, a scopolamine group and a dolantin group, 80 cases in each group. The acupuncture group was treated by acupuncture at unilateral or bilateral Neiguan (PC 6) and Zusanli (ST 36). The scopolamine group was treated by intramuscular injection of scopolamine combined with intravenous drip of scopolamine, and the dolantin group was treated by intramuscular injection of dolantin. The clinical therapeutic effects were observed 30 min after drug administration or acupuncture, and the onset time of effect and adverse reactions were compared among the groups.

RESULTSThe total effective rate of 95.0% (76/80) in the acupuncture group had a similar therapeutic effect to 92.5% (74/80) in dolantin group (P>0.05), which were both superior to 76.3% (61/80) in scopolamine group (both P<0.05). The onset time of (13.24 +/- 2.12) min in the acupuncture group was significant earlier than (23.11 +/- 6.22) min in scopolamine group and (22.17 +/- 3.15) min in dolantin group (both P<0.05), and compared with the other two groups, the adverse reactions in the acupuncture group were significant decreased (both P<0.05).

CONCLUSIONAcupuncture at Neiguan (PC 6) and Zusanli (ST 36) has a good analgesic effect with a low incidence of adverse reactions, which is superior to that of dolantin and scopolamine.

OBJECTIVETo investigate the expressions of phosphorylated Smad2 (P-Smad2) and phosphatase and tensin homolog deleted on chromosome ten (PTEN) in hepatocellular carcinoma (HCC) tissues.

METHODSThe expressions of P-Smad2 and PTEN were detected using Envision immunohistochemical technique in 31 cases of HCC tissues, 25 cases of HCC adjacent liver tissues and 13 cases of non-hepatocellular carcinoma tissues.

RESULTSThe positive expression and staining intensity of PTEN in the cytoplasm of HCC cells (64.5%, 4.19+/-3.31) was significantly lower than those of the cells of the cancer adjacent tissues and non-cancerous tissues (96.0%, 7.88+/-0.93; 100%, 7.77+/-0.93). The staining intensity of PTEN in the cytoplasm of Edmondson pathologic grade III HCC cells was lower than those of the Edmondson grade I. The expression of PTEN was negatively correlated with intrahepatic vascular cancer thrombi (r=-0.43) and the expression of PTEN in the nuclei or cytoplasm of liver cells was negatively correlated with the liver disease progressions (r=-0.34). The positive rate and expression intensity of phosphorylated Smad2 in nuclei of HCC cells were the same as those in cancer adjacent and non-tumor liver tissues. The expression was mostly in the nucleus and cytoplasm of Edmondson grade I HCC cells, cancer adjacent liver tissue cells and non-tumor liver tissues, but its expression was only in the nuclei of Edmondson grade II and III HCC cells. The phosphorylated Smad2 expression appeared in the nuclei and in the cytoplasm of liver cells and it was positively correlated with the severity of the tumor pathology (r=0.22). Spearman correlation analysis revealed a significant inverse correlation between PTEN and phosphorylated Smad2 in HCC tissues (r=-0.73).

CONCLUSIONSThe aberrant expressions of PTEN and phosphorylated Smad2 and their interaction may play an important role in the pathogenesis of hepatocellular carcinoma.

Objective To explore application effect of modified postural drainage on treating stubborn pulmonary infection after cardiothoracic surgery.Methods Totals of 88 patients with stubborn pulmonary infection after cardiothoracic surgery were chosen,and randomly divided into the experimental group (n =47)and the control group (n =41).The control group received conventional drug therapy and nutritional support treatment,while the experimental group received modified postural drainage method in addition.Two groups'treating time,rehabilitation conditions,antibiotic use time were compared.Results Fifteen days after modified postural drainage,41 cases in the experimental group and 21 cases in the control group had smaller lesion,and the difference was statistically significant (x2 =32.19,P ＜ 0.01).The score of physical function,physical role,general health condition,vitality,and psychological health in SF-36 scale was respectively (52.22 ±9.27),(56.87 ± 9.22),(58.69 ± 7.54),(49.33 ± 8.25),(53.28 ± 7.89) in the experimental group,and (41.54 ± 10.11),(44.28 ± 10.41),(45.22 ± 8.29),(33.21 ± 9.57),(42.74 ± 8.03) in the control group,and the differences were statistically significant (t =3.45,2.65,4.21,3.54,2.58,respectively;P ＜0.05).There were no obvious adverse reactions in both groups.Conclusions Modified postural drainage,better than simple drug therapy,can promote the recovery of stubborn pulmonary infection after cardiothoracic surgery.

OBJECTIVEPatient with myocardial bridging (MB) usually has a benign prognosis, but some MB patients might experience myocardial ischemia, infarction and sudden cardiac death, especially during active physical activities. The purpose of the study was to study the stress-induced blood flow changes of the mural coronary artery in MB patients determined by intracoronary Doppler.

METHODSIn 8 patients with MB, the basic average peak velocity (bAPV), hyperemic average peak velocity (hAPV) of blood flow, coronary flow reverse (CFR) proximal and distal to the mural coronary artery were measured before and during intravenously dobutamine (10 microg kg-1 min-1, then add 10 microg kg-1 min-1 at 3 min interval till 40 microg kg-1 min-1) by intracoronary Doppler.

RESULTSThe baseline mural coronary diameter reduction was (51.7+/-21.4)% and significantly increased to (90.0+/-12.7)% (P<0.01) during dobutamine infusion. bAPV on the segments proximal and distal to the mural coronary artery significantly increased from (19.83+/-5.84) cm/s and (20.75+/-4.91) cm/s to (31.52+/-10.93) cm/s and (30.46+/-9.01) cm/s (all P<0.05 vs. baseline) respectively post dobutamine infusion. CFR measured at proximal and distal to myocardial bridging also significantly decreased from (2.91+/-0.62) and (2.46+/-0.82) to (2.17+/-0.66) and (1.83+/-0.51) (all P<0.01).

CONCLUSIONStress can significantly increase the compression of intramural coronary artery and reduce CFR on coronary segments both proximal and distal to the MB. Thus, active exercise might induce myocardial ischemia in patients with myocardial bridging.

Objective:To assess the clinical effect and safety of comprehensive therapy of traditional Chinese medicine(TCM)in the treatment of erectile dysfunction(ED)with damp-heat stasis.Methods:We selected 108 cases of ED with damp-heat stasis meeting the inclusion criteria and treated with tadalafil(the control group,n=54)or tadalafil+comprehensive TCM therapy(the trial group,n=54)in the First Affiliated Hospital of Henan University of Chinese Medicine in the same period.After 8 weeks of treatment,we recorded the patients'scores on IIEF-5,TCM syndrome,erectile quality(EQS),9-Item Patient Health Questionnaire(PHQ-9)and Generalized Anxiety Scale 7(GAD-7).At 16 weeks of our study,we collected the efficacy parameters,safety indicators and adverse reactions by telephone follow-up and compared the data obtained between the two groups of patients.Results:Totally,103 of the patients completed the study,51 in the control and 52 in the trial group.Compared with the baseline,the IIEF-5 and EQS scores were both markedly increased after 8 weeks of treatment in the trial group(12.35±3.00 vs 18.36±2.82,P＜0.05;39.5[30.25-43]vs 67.5[54.5-76.75],P＜0.05)and the control(11.96±2.79 vs 15.88±3.86,P＜0.05;38.0[29-42]vs 56[49-64],P＜0.05),even more significantly in the former than in the latter(P＜0.05);the TCM syndrome and GAD-7 scores were remarkably decreased in the trial(9.5[8-12]vs 4.0[2.25-5],P＜0.05;5[2.25-6.75]vs 2.5[1-4.75],P＜0.05)and the control group(10.0[8-12]vs 5.0[3-6],P＜0.05;5.0[3-6]vs 4.0[2-5],P＜0.05),even more signif-icantly in the former than in the latter(P＜0.05),so were the PHQ-9 scores(P＜0.05),but with no statistically significant differ-ence between the two groups(P＞0.05).The IIEF-5 scores of the two groups remained significantly higher than the baseline during the follow-up(P＜0.05),even higher in the trial than in the control group(17.04±2.60 vs 14.16±3.34,P＜0.05).No obvious abnormal safety indicators or adverse events were observed during the study.Conclusion:Comprehensive TCM therapy combined with tadalafil is superior to tadalafil alone in the treatment of ED with damp-heat stasis,and has a better long-term efficacy and a higher safety.

Objective:To systematically evaluate the effect and safety of electroacupuncture in the treatment of chronic prostati-tis/chronic pelvic pain syndrome(CP/CPPS).Methods:We searched the major Chinese and English databases of CNKI,Wan-fang Data,VIP,CBM,PubMed,Cochrane Library,Web of Science and Embase for randomized controlled trials(RCT)on electroa-cupuncture or combination therapy in the treatment of CP/CPPS published from the establishment of the databases to August 2024.The dichotomous data and continuous data were represented by risk ratio(RR)and mean difference(MD)respectively,both with 95％confidence interval(CI).We analyzed the data with the Revman(v.5.4)software and assessed the quality of the evidence in each RCT using the Grading of Recommendations Assessment,Development and Evaluation system(GRADE).Results:Totally 17 RCTs were identified,involving 1 404 cases of CP/CPPS treated by electroacupuncture or combination of electroacupuncture with medication or with other therapies(the trial group)or by medication with Western or Chinese drugs alone(the control group).Compared with the control group,the trial group showed a significantly higher rate of clinical effectiveness(RR=1.25;95％CI:1.18-1.32;P＜0.05),decreased CPSI scores(MD=-4.56;95％CI:-5.01--4.11;P＜0.05),improved CPSI-pain,-urination and-quali-ty of life scores,and increased maximum and average urinary flow rates.And electroacupuncture did not increase the likelihood of ad-verse reactions.Conclusion:Medium-quality evidence suggests that electroacupuncture is beneficial complementary and alternative therapy for CP/CPPS,with a significant advantage in improving the NIH-CPSI scores of the patients.However,more high-quality multi-centered RCTs with larger sample sizes are still needed to further verify the effect of electroacupuncture on CP/CPPS.

OBJECTIVETo investigate the function of interferon alpha (IFNalpha) in a Chinese marmot model of hepatitis B, we expressed the Chinese marmot (Marmota himalayana) IFNalpha family gene (IFNA) in eukaryotic cells and prokaryotic cells.

METHODSEukaryotic and prokaryotic expression plasmids harboring Chinese marmot interferon alpha gene with different genotypes were generated using molecular cloning technology. We detected the biological activity of all expression products by viral protection assay, and analyzed their differences and species restriction of the biological activity.

RESULTSThe Chinese marmot functional genotype IFNalpha was expressed in the baby hamster kidney (BHK) cell line, and these products protected WH12/6 cells challenged by encephalomyocarditis virus (EMCV). The Chinese marmot IFN-alpha5 also expressed in E. Coli induced by IPTG, and purified fusion protein had antiviral biological activity. The biologic activity displayed differences among different subtype IFNalpha, and it had strict species restriction.

CONCLUSIONThe IFNalpha family gene of the Chinese marmot can be expressed in both eukaryotic and prokaryotic cells, and the expression products show antiviral activity in a protection assay. This study provides, for the first time, evidence that IFNalpha from the Chinese marmot has an antiviral function in vitro and can be used to improve the efficacy of current therapies for HBV infection in our Chinese marmot model.

OBJECTIVESTo study the effects of tumor suppressor in lung cancer-1 (TSLC1) on human hepatocyte carcinoma cell line HepG2.

METHODSA full length of TSLC1 cDNA was amplified from RNA of normal human liver cells by RT-PCR, and it was cloned into a pCI-neo expression vector and transfected into human hepatocellular carcinoma cell line HepG2. The HepG2 cells transfected with this plasmid (experimental group) and those treated with pCI-neo vector (control group) and without any treatment (blank group) were compared. Cell morphology was studied microscopically and cell growth was analyzed with MTT assay. FACSort flow cytometry analysis was performed to assess the cell cycle distribution and apoptosis.

RESULTSA stable cell line expressing TSLC1 protein was successfully established. Morphologically, cells of the experimental group were tightly aggregated when compared with those of the control and blank groups. The growth of TSLC1-transfected cells was significantly suppressed in vitro compared with those of the control and blank groups. The amount of G0-G1 cells was 63.66%+/-3.83% (P less than 0.01) in the experimental group, while those of the control and blank groups were 47.45%+/-0.91% and 54.47%+/-0.96% respectively. The amount of S phase cells in the experimental group, 22.90%+/-6.04%, was significantly lower (P less than 0.05) than that of the control group (36.58%+/-0.61%) and the blank group (33.61%+/-2.99%), which suggested a G0-G1 cell cycle arresting. The number of cells in early and late phase apoptosis (17.09%+/-0.20% and 16.11%+/-0.40% respectively) were significantly higher than those of the control and blank groups (P less than 0.01).

CONCLUSIONSTSLC1 strongly inhibits the growth of HepG2 cells in vitro and induces apoptosis of the cells, suggesting that TSLC1 may have a tumor suppressor function in HCC.
