Objective To evaluate the clinical efficacy and safty of le-vocarnitine combined with alprostadil in the treatment of diabetic ne-phropathy.Methods A total of 68 patients with diabetic nephropathy were randomly divided into control group ( n=34 ) and treatment group (n=34).Control group was given alprostadil 1 mL, qd by intravenous drip.Treatment group was received levocarnitine 1 g, qd by intravenous drip on the basis of control group .The course of two groups was 28 d. The clinical efficacy , biochemical indexes before and after treatment and the incidence of adverse drug reactions were compared between two groups.Results After treatment , the total effective rate of control group was significantly lower than that of treatment group ( 67.65% vs 94.12%, P<0.05).After treatment, the levels of serum 24 h urinary protein , urinary microglobulin , urea nitrogen , cystatin C , homocysteine , glycosylated hemoglobin , transforming growth factor -β1 ,Ⅳcollagen in two groups were significantly decreased ( P<0.05 ) , and those indexes of treatment group after treatment were significantly lower than those of control group (P<0.05).After treatment, the levels of serum of serum creatinine , 25 -hydroxy vitamin D 3 in two groups were decreased with significant difference ( P <0.05 ) , and the treatment group was more obvious ( P<0.05 ).The incidence of adverse drug reactions in control group was significantly higher than that in treat -ment group (23.53%vs 8.82%,P<0.05 ) .Conclusion Levocarnitine combined with alprostadil have a definitive clinical efficacy and safety for the treatment of diabetic nephropathy .

OBJECTIVETo investigate the differential expression of apoptosis associated gene Bcl-2 and Bax through cell cycle and its possible clinical meaning.

METHODSThe prostate cancer cell line PC-3 was synchronized in M, G1, S and G2 phase using modified thymine deoxyriboside blockage and high pressure N2O technique. The efficiency of synchronization was detected by flow-cytometry. RT-PCR and Western blot methods were used to examine the expression of Bcl-2 and Bax in mRNA and protein level.

RESULTSThe synchronized rate of M, G1, S and G2 phase were 92.1%, 87.0%, 80.2% and 75.9% respectively. Bcl-2 was constitutively expressed through the cell cycle, but both the mRNA and protein expression level of Bcl-2 were very high in the G1 phase, dramatically decreased in M, S and G2 phase. The expression level of Bax had no change through the cell cycle.

CONCLUSIONSCell cycle could influence the expression level of Bcl-2 significantly but not Bax, these might have some clinical relevance.

OBJECTIVETo observe the specific clinical efficacy of electroacupuncture at Lingtai (GV 10) and Shendao (GV 11) on premature heartbeat.

METHODSSeventy-two cases of premature heartbeat were randomized into an observation group and a control group. In the observation group, electroacupuncture was applied at Lingtai (GV 10) and Shendao (GV 11). In the control group, electroacupuncture was applied at bilateral Xuanzhong (GB 39). The treatment was given once a day and 10 times made one session in both groups. Respectively, the dynamic electrocardiogram detection was done before treatment and after one session of treatment in each group.

RESULTSThe total effective rate was 47.1% (16/34) in the observation group and 6.5% (2/31) in the control group. The efficacy in the observation group was superior to that in the control group, presenting the statistical significant difference in comparison (P < 0.05).

CONCLUSIONElectroacupuncture at Lingtai (GV 10) and Shendao (GV 11) has specific clinical efficacy on premature heartbeat.

OBJECTIVETo study the value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy diseases (DMD) in children.

METHODSEight children with DMD were enrolled as DMD group and 10 healthy children as the control group. The echogenicity of the rectus femoris muscle and the gap between the gastrocnemius and soleus muscles in the two groups were detected by high-frequency ultrasound.

RESULTSCompared with the control group, rectus femoris and gastrocnemius muscles in the DMD group showed increased echogenicity and their muscle fibers were arranged irregularly, and the gap between the gastrocnemius and soleus muscles became wilder (P<0.01).

CONCLUSIONSHigh-frequency ultrasound is valuable in the diagnosis of DMD.

Objective We aimed to explore the clinical efficacy of precise electro-acupuncture stimulation in the pterygopalatine fossa for the treatment of chronic sinusitis.Methods In total,40 patients with chronic sinusitis who visited the Xiyuan Hospital,China Academy of Chinese Medical Sciences between January 2022 and January 2023 were selected.The subjects were randomly divided into two groups:the treatment group(receiving precise electro-acupuncture in the pterygopalatine fossa)and the control group(receiving standard western medical treatment),with 20 cases in each groups.The treatments were administered twice a week for a period of 12 weeks.The effectiveness of the treatments was evaluated through computed tomography(CT)of the sinus changes and the Lund-Mackay scoring system.Results In cases of total opacity and partial opacity,there were significant differences between the two patient groups before and after treatment(P<0.05).Intra-group comparison revealed statistically significant improvements in both groups before and after treatment(P<0.05).The treatment group exhibited significant improvement in various sinus conditions(P<0.05),while in the control group,a significant improvement was only observed in the left maxillary sinus(P<0.05).Inter-group comparison also demonstrated that the treatment group's improvements were superior to those of the control group across multiple indicators(P<0.05).Conclusion The precise electro-acupuncture stimulation technique in the pterygopalatine fossa demonstrated significant therapeutic effects in the treatment of chronic sinusitis,with superior outcomes with respect to radiological changes compared to standard western medicine treatment.

OBJECTIVETo investigate the effect of chronic enhanced external counterpulastion (EECP) on gene expression profiles of arterial endothelial cells (ECs) of pigs fed with high-cholesterol diet.

METHODSEight male pigs were fed with high-cholesterol diet for 12 weeks to induce arteriosclerosis and subjected to EECP for accumulative 36 h (2 h every other day for 18 sessions). Another 8 pigs on cholesterol-enriched diet and 6 normally fed pigs served as the arteriosclerosis model group and normal control group, respectively, and the high-cholesterol diet was maintained until the end of EECP treatment. The coronary artery was then isolated for transmission electro microscopy, and the abdominal aorta was observed using Sudan III staining. The gene expression profiles in ECs from the thoracic aorta using cDNA microarrays.

RESULTSMacrophages and foam cells were detected beneath the ECs in the coronary artery of pigs in the model group, but not in the other two groups. The ratios of Sudan III-positive area in the celiac aorta were significantly lower in normal control and EECP groups than in the model control group (P<0.05). Compared with the normal control group, the gene expressions of integrins-beta1 and CTGF were up-regulated in the model group. Compared with the model group, the expressions of integrins-beta1, CTGF and VCAM-1 were down-regulated and eNOS up-regulated in EECP group.

CONCLUSIONChronic EECP may reduce endothelial injury, down-regulate the gene expression level of integrin-beta1, CTGF and VCAM-1, lower cholesterol uptake and attenuate arterial endothelial inflammation to protect the pigs fed with high-cholesterol diet from arteriosclerosis.
