AIM: To investigate the effect of ginsenoside-Rg3 on the expression of vascular endothelial growth factor (VEGF) and tumor necrosis factor-α (TNF-α) in retina with diabetic rats and its roles in preventing neovascularization in diabetes. METHODS: Sixty male Wistar rats were divided into 3 groups randomly: negative control group, diabetic control group and ginsenoside-Rg3 treatment group (5mg/kg, 0.2mg/mL) followed by establishing diabetic model. The expression of VEGF and TNF-α were measured after 8 weeks. RESULTS: There were significant differences among negative control group, diabetic control group and ginsenoside-Rg3 treatment group in the expression of VEGF and TNF-α (F=129.363, 211.992; all the P<0.01). VEGF and TNF-α expression were significantly higher in diabetic control group and ginsenoside-Rg3 treatment group than that in negative control group (P<0.01), with a significant reduction in ginsenoside-Rg3 treatment group than that in diabetic control group (P<0.01). CONCLUSION: Ginsenoside-Rg3 can down-regulate the expression of VEGF and TNF-α in retina, which may interfere in the development of diabetic retinopathy.

Objective To observe the intervention effect of premature pathological jaundice treated with conventional blue light phototherapy combined with acupoint massage plus body massage. Methods Ninety premature infants with pathological jaundice were randomized into control group 1, control group 2 and observation group, 30 cases in each group. The control group 1 was given blue light phototherapy plus oral use of vitamin B2, the control group 2 was given body massage based on the treatment for the control group 1, and observation group was given acupoint massage based on the treatment for the control group 2, the treatment for the three groups lasting for 7 continuous days. Before and after treatment, the levels of transcutaneous bilirubin (TCB), serum total bilirubin (TB), and serum direct bilirubin (DB) were observed, and then the therapeutic effects on jaundice in the three groups were compared. Results After treatment, the overall therapeutic effect and the daily decline of TCB, TB and DB in the observation group were superior to those in the two control groups, the difference being significant (P < 0.05 or P < 0.01). In the control group 2, the post-treatment average decline of TB and the decline of TCB on treatment day 4-7 were superior to those in the control group 1, the difference being significant(P<0.05). Conclusion Acupoint massage plus body massage is effective and safe for the treatment of pathological jaundice in premature infants, and the therapy being simple and practical.

Objective To explore the modification of bionic silk fibroin nerve conduits (SF-NCs) by silk sencin.Methods The innovative SS/SF blended-NCs was fabricated by a vertical sequential cooling thermal induced phase separation (TIPS) processing with SF solution added sericin in proportion,its morphology was observed by Scanning electron microscopy (SEM),X-ray diffraction (XRD) and infrared spectroscopy (FTIR) were used to detect its internal molecular structure.MTT assay was used to quantitatively analyzed the PC12 cells viability co-cultured with the innovative SS/SF-NCs,SEM was used to observe the adhesion and morphology of PC12 cells seeded into the innovative SS/SF,PC12 cells were used to assess the NGF bioactivity released from the SS/SF.Results The SEM results showed that the new fabricated SS/SF-NCs had linearly oriented lamellar-like multiple-channel which distributed evenly,got great changes on the channel microstructure and their mechanical properties had been greatly improved,compared to SF-NCs.The XRD and FTIR results showed that the SS/SF-NCs had the similar internal molecular structure with natural silk.The spaces between parallel lamellar-like channels,porosities and compressive strengths of the SS/SF-NCs decreased with decreasing Sequential freezing temperature.MTT assay results showed that the viability of PC12 cell was better than the control group (P ＜ 0.05).The SEM observation indicated that PC12 cells showed good adhesion and differentiation with neuritis outgrowth during the period of co-culture with the SS/SF-NCs.NGF release from the innovative SS/SF-NCs was prolonged over 4 weeks,and remained bioactive.Conclusion The new fabricated SS/SF-NCs modified though silk sericin,which was highly bionic the structure of peripheral nerve fasciculus,had excellent mechanical properties and could be used as another alternative of artificial nerve conduits.

Objective To evaluate the clinical application of CT-guided localization with combination of methylene blue and a Hookwire system for small pulmonary nodules (SPNs) before video-assisted thoracoscopic resection.Methods CTguided localization the SPNs before resection in 56 patients and 60 nodules,then underwent video-assisted thoracic surgery (VATS) resection.Among 56 patients,19 males and 37 females,aged from 35 to 81 years,mean age was (61.1 ±8.9)years.Results SPNs diameter (6.80 ±4.12) mm,distance from the parietal pleura (15.38 ±4.63) mm.CT-guided localization success rate was 100％,positioning time (10.76 ± 8.17) min,8.9％ (5/56) had micro pneumothorax aftet positioning,7.1％ (4/56) occurrence of needle tract bleeding,no conservative treatment.VATS resection rate was 100％.The pathology of 60 lesions were shown:Bronchiolo-alveolar carcinoma(BAC) were 33 lesions(55.0％),BAC and adenocarcinoma were 11 lesions(18.3％),Atypicaladenomatous hyperplasia (AAH) were 7 lesions (11.8％),Inflammation were 4 lesions (6.7％),Harmatoma were 3 lesions(5.0％),Tuberculoses were 2 lesions(3.3％).Conclusion CT-guided localization with combination of methylene blue and a Hookwire system before video-assisted thoracoscopic resection is a promising technique for small solitary pulmonary nodules.It could play an important role in accurate localization of small pulmonary nodules,and it is a safe technique with clinical application.
