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.

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.

The aim of this study was to set up a new method for 5, 10-Methylenetetrahydrofolate reductase (MTHFR) single nucleotide polymorphisms (SNP) genotyping, and to investigate the hereditary susceptibility of hematological malignancy. Prepared an aimed gene microarray based on cDNA microarray theory, dual-color fluorescence hybridization was used to detect SNP loci, and DNA sequencing was performed to confirm the results. The MTHFR C677T SNP loci of 157 controls and 127 patients with hematological malignancies (30 multiple myeloma, 28 non-Hodgkin's lymphoma, 22 acute lymphoblastic leukemia, 40 acute myeloid leukemia, 7 chronic myeloid leukemia) from Jiangsu province were detected. The results showed that after overlapping, homozygous wild type, heterozygote type and homozygous mutant type yielded green, yellow and red fluorescence, respectively. DNA sequencing validated these results. The allele frequency of 677C and 677T in patients and controls were 58.7% and 66.9%, 41.3% and 33.1% respectively, showing statistically significant difference (chi2 = 4.077, P = 0.043). 677TT genotype showed a significantly higher risk of MM (OR = 4.21; 95% CI = 1.50 - 11.83; P = 0.006). It is concluded that this microarray-based method is accurate, high-throughput and inexpensive, suitable for SNP genotyping in a large number of individuals. C677T polymorphisms influence the risk of hematological malignancies. 677TT genotype is susceptive to MM.

OBJECTIVETo explore the mitochondrial toxicities induced by zidovudine (AZT) and adefovir dipivoxil (ADV) antiviral drugs using a rat model system.

METHODSTwelve healthy Sprague-Dawley rats were randomly divided into three equal groups and treated by oral gavage with zidovudine (125 mg/kg/day), adefovir (40 mg/kg/day), or saline (equal volume) for 28 days. The rats' body weights were measured once a week, and blood was collected every two weeks for blood and biochemical tests. All animals were sacrificed at the end of treatment, and liver, kidney, skeletal muscle, and cardiac muscle were collected by necropsy. Mitochondria were isolated from the respective tissue samples, and the activities of respiratory chain complexes were measured. DNA was purified from each sample and the mitochondrial DNA (mtDNA) content was monitored by quantitative real time PCR. Mitochondrial morphology was analyzed under electron microscope.

RESULTSNo significant adverse effects, including body weight loss, abnormal blood or biochemistry, were observed in rats treated with AZT or ADV. The activities of mitochondrial cytochrome c oxidase in liver and cardiac muscle were slightly decreased in rats treated with AZT (liver: 9.44+/-3.09 vs. 17.8+/-12.38, P?=?0.21; cardiac muscle: 32.74+/-5.52 vs. 24.74+/-20.59, P?=?0.28; kidney: 4.42+/-1.53 vs. 14.45+/-13.75, P?=?0.18; skeletal muscle: 33.75+/-8.74 vs. 40.04+/-2.49, P?=?0.45). The mtDNA content was significantly decreased in cardiac muscle of AZT-treated rats (cardiac muscle: 0.15+/-0.13 vs. 0.32+/-0.42, P?=?0.85). The morphology of mitochondria in liver, kidney, skeletal muscle, and cardiac muscle was significantly altered in the AZT-treated rats and included disappearance of the outer membrane, severely damaged structure, and swollen or completely absent cristae. No obvious effects were noted in the ADV- or saline-treated rats.

CONCLUSIONSignificant adverse effects related to mitochondrial toxicity were observed in rats treated with AZT. The slightly decreased mtDNA content in ADV-treated rats may suggest that this antiviral drug can also cause mitochondrial toxic effects.
