Objective To inquire clinical effects of hysteroscopic electroresection in the treatment of submucous hysteromyoma. Methods A retrospective analysis regarding curative effects of hysteroscopic electroresection in 72 cases of submucous hysteromyoma was carried out. Results The resected myoma was 1.5~7 cm in diameter, and the number of resected myoma was 1~3. The operation time was 10~90 min (mean, 30 min). The operation was accomplished on one session in all the 72 cases. No uterine perforation, bleeding and bowel injuries took place. Postoperative follow-up for 4~20 months in the 72 cases reported a satisfaction rate of 97 2% (70/72). Out of 6 patients who had pregnancy desire, 2 were pregnant with child and 1 of them had a delivery. Conclusions Hysteroscopic electroresection in the treatment of submucous hysteromyoma is safe and effective. It can markedly improve the menstruation and elevate the pregnancy rate.

Objective To explore the effects of estrogen on stress-induced senescence of vascular smooth muscle cells (VSMCs) and the underlying mechanisms. Methods The VSMCs of passage 2-3 cultured from female SD rats were induced into senescence by exposing to 150μmol/L H2O2 in the presence or absence of different concentrations(10-10mol/L-10-8mol/L) of 17β-estradiol (E2). The expressions or activities of senescence associated marker DcR2, senescence-associated beta-galactosidase (SA-β-Gal), oncogene Ras and p21WAF1 were detected by flow cytometry, cytochemical staining, pull-down assay or Western blotting analysis. Results Flow cytometry analysis showed that in the physiological concentrations, E2 significantly inhibited the H2O2-promoted high-level expression of DcR2 of VSMCs in a dose-dependent manner, with a highest inhibitive rate at 14.48%±0.6%(E2=10-8 mol/L;P<0.05, n =3);this inhibitive effect could be blocked by a E2 receptors inhibitor ICI 182,780. Cytochemistry staining showed that the rate of SA-β-Gal positive VSMCs induced by H2O2 decreased in presence of 10-8mol/L E2 (20.5%±1.4% vs 9.6%±0.9%;P<0.05, n =9). Pull-down assay and Western blotting analysis revealed that administration of 10-8mol/L E2 obviously reduced the H2O2-induced activity of Ras (0.60±0.06 vs 0.26±0.04;P<0.05, n =3) and expression of p21WAF1 (0.46±0.04 vs 0.33±0.02;P<0.05, n =3). Conclusion E2 exerts, an inhibitive effects on stress-induced senescence of VSMCs by suppressing the activity of Ras and expression of p21WAF1. This finding suggests a novel mechanism for the hormone's anti-atheroschlerotic effects.

Oncogene and antioncogene play contrary effects on the cell growth and proliferation controlling process, and cancer occurs when the presence of imbalance expression between them. That means there is yin-yang relationship between oncogene (yang) and antioncogene (yin), and also inside both of them. Taking the oncogene myc and antioncogene p53 for example, the yin gene p53 acts, in the yin side, to promote cell apoptosis and inhibit cell growth, while in the yang side, it facilitates for repairing the injured DNA to keep cell survival; the yang gene myc, promoting cell growth and proliferation in the yang side and inducing cell apoptosis in the yin side. To elucidate the yin-yang reactions between oncogene and antioncogene would be of important significance in the all-round and profound research of cancer.

The positive rate of corneal FL was 37. 7% (46/122), which was higher than that of the control group (10. 7%, 13/122), there was a statistically significant difference (X2= 24. 34, P<0. 05).?CONCLUSlON:CRF patients with a decrease in tear film stability and tear secretion are susceptible population to dry eye, clinically should be paid attention to the treatment.

Objective To investigate the electrophysiological characteristics of chronic alcoholic myopathy. Methods Muscle fiber conduction velocity, peripheral nerve conduction velocity, and induced potentials in 26 patients with chronic alcoholic myopathy, 13 patients with chronic alcoholic peripheral neuropathy, 21 patients with chronic alcoholic neuromuscular damage, and 20 normal subjects were detected by electromyography and single fiber electromyography. Results Electromyography revealed myogenic changes in 9 cases in the myopathy group, neurogenic changes in 7 cases in the peripheral neuropathy group, and both kind of changes in 4 cases in the neuromuscular damage group. Compared with the normal subjects, neuromuscular jitter and fiber density increased in all patients ( P 0.05). Slowed sensory nerve conduction velocity was found in 28 patients (82.35%) with peripheral neuropathy or neuromuscular damage. Conclusion Electromyography and determination of nerve conduction velocity can be used to differentiate the alcoholic myopathy from peripheral neuropathy. The abnormal muscle fiber conduction velocity can be helpful for the confirmation of myopathy.

Objective To compare the value of two‐dimensional shear wave elastography (2D‐SWE) and real‐time tissue elastography (RTE) in the assessment of liver fibrosis in patients with chronic liver disease. Methods One hundred and ten patients with chronic liver disease scheduled for liver biopsy were studied. Both 2D‐SWE and RTE were performed on these patients in a same day. The correlation coefficient of liver fibrosis level, receiver operating characteristic (ROC) curve of S≥2, and S=4 of 2D‐SWE and RTE were compared according to pathologic results. Results The correlation coefficient of liver fibrosis level for 2D‐SWE ( r =0 7.76, 95% CI 0 6.83 -0 8.45, P =0.000) was higher than that of RTE ( r =0 5.61, 95% CI 0 4.07-0 6.84, P =0.000)( Z =2 9.3, P =0.003). The area under ROC curve for S≥2 and S=4 of 2D‐SWE were 0 8.66 and 0 9.57 respectively, RTE were 0 7.50 and 0 8.43 respectively, which indicated that 2D‐SWE was better than RTE. Conclusions The diagnostic performance of 2D‐SWE was better than RTE for the assessment of liver fibrosis and cirrhosis.

Objective To observe clinical efficacy of Qilin Pills combined with Three-Spot Caressing in the treatment of acquired non-consolidated kidney qi premature ejaculation (PE). Methods Totally 129 acquired non-consolidated kidney qi PE patients were randomly divided into TCM group, Fangzhognshu group and combination group. TCM group was given Qilin Pills, 6 g each time, three times a day, orally. Fangzhognshu group was guided to conduct Three-spot Caressing during sexual intercourse, no less than twice a week. Combination group was given Qilin Pills and Three-spot Caressing with the same method as Fangzhognshu group. The treatment course for each group lasted for 8 weeks. Before and after treatment of 4 weeks, 8 weeks and 4 weeks after with drawal, the intravaginal ejaculatory latency time (IELT), Chinese Index of Sexual Function for Premature Ejaculation-5 (PECI-5) scores and TCM syndrome scores (TCMS) were compared. Results Compared with before treatment, IELT increased in three groups at different time points after treatment (P<0.05). In the combination group, IELT was superior to the other two groups (except for TCM group after 4-week treatment), with statistical significance (P<0.05). Compared with before treatment, PECI-5 scores improved in three groups (except for Q6 and Q7 in Fangzhongshu group after 4-week treatment) at different time point after treatment (P<0.05). The improvement of Q5, Q6 and Q7 scores in PECI-5 of combination group was significantly better than that in the other two groups at 8-week treatment and 4-week after treatment (P<0.05). Compared with before treatment, TCMS in TCM group and combination group were improved significantly (P<0.05), PE and loss of libido score improved significantly in Fangzhongshu group (P<0.05);mental malaise and move spontaneous perspiration were significantly improved at 8-week treatment and 4 weeks after treatment (P<0.05). The improvement in TCMS was significantly better in combination group than that in the other two groups at 8-week treatment and 4 weeks after treatment (P<0.05). Conclusion Qilin Pills combined with Three-Spot Caressing has definite and long-term efficay for the treatment of acquired non-consolidated kidney qi PE.

The effect of amygdalin joint hydroxysafflor yellow A (HSYA) on the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and the possible mechanism were studied and explored. Chondrocytes were obtained from endplate of one-month SD rat intervertebral discs and cultured primary endplate chondrocytes. After identification, they were divided into normal group, induced group, amygdalin group, HSYA group and combined group. CCK-8 kit was adopted to detect the proliferation of the endplate chondrocytes. FCM was measured to detect the apoptosis. Real-time PCR method was adopted to observe the mRNA expression of Aggrecan, Col 2 alpha1, Col 10 alpha1, MMP-13 and the inflammatory cytokines IL-1beta. The protein expression of Col II, Col X was tested through immunofluorescence. Compared with the normal group, the proliferation of the endplate chondrocytes decreased while the apoptosis increased (P < 0.05). With down regulation of the mRNA expressions of Aggrecan, Col 2 alpha1 and up regulation of the mRNA expressions of Col 10 alpha1, MMP-13, IL-1beta (P < 0.05), the protein expression of Col II decreased while the protein expression of Col X increased. Compared with the induced group, amygdalin group, HSYA group, the combined group could inhibit the apoptosis and promote the proliferation (P < 0.05). They could increase the mRNA expressions of Aggrecan and Col 2 alpha1 while decrease the mRNA expressions of Col 10 alpha1, MMP-13 and IL-1beta (P < 0.05). They could also enhance the protein expression of Col II while reduce the protein expression of Col X. The effect of the combined group was significantly better than that of amygdalin and HSYA. Amygdalin joint HSYA could inhibit the degeneration of the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and better than the single use of amygdalin or HSYA.
