0.05). However, there was significant difference between the "open-window" or hemilaminectomy group and total laminectomy group. The time of returning to work and the rate of returning to previous work were 4.3 months and 84.6% in "open-window" group, 4.6 months and 86.4% in hemilaminectomy group and 4.4 months and 77.8% in total laminectomy group respectively. The height loss of involved disc spaces was discovered in the postoperative radiographs in all the patients. However, no segmental instability was found in the majority of these patients. Conclusion 1) "Open-window" or hemilaminectomy may achieve satisfactory long-term results for treatment of lumbar disc herniation. 2) No definite correlation exists between the height loss of involved disc space and segmental instability or nerve root entrapment. 3) Discectomy is still a reliable and effective surgical procedure for the treatment of lumbar disc herniation before the reliability of any disc replacement is confirmed in the long-term follow-up survey.

Expression of apelin mRNA in the isolated mouse adipocytes was confirmed by Northern blot. The level of apelin mRNA increased during stage of differentiation of 3T3-L1 cells. Insulin up-regulated the apelin expression in 3T3-L1 adipocytes, suggesting that apelin expression in adipocyte may correlate with obesity, insulin resistance and hypertension.

CDKs proteins are a kind of cell cycle protein-dependent kinases, which serve as important roles in controlling cell division and transcriptional stages. Among them, CDK9, as a key regulator responsible for the transcriptional elongation of cells, drives the development of various malignant cells and is considered as an important target in the field of anti-tumor drug development. However, the CDK family proteins feature high conservativeness and similarity in structure, leading to the poor selectivity and severe side effects for traditional small-molecular CDK9 inhibitors, which has limited their clinical applications. In view of this, there is an urgent need to investigate CDK9 targets through a novel strategy. The PROTAC is an emerging drug discovery strategy that the degrader could specifically recognize the target protein through indirect linkage with ubiquitin ligases and ultimately eliminate the target protein through the ubiquitination degradation system. This paper provides a brief overview of the structure and function of CDK9 protein, its relationship with the poor prognosis of clinical diseases, as well as the currently reported small molecular inhibitors. The latest research progress on the targeted degradation of CDK9 protein based on PROTAC technology is highlighted. Finally, the development prospects of this target protein in this novel technology field are summarized and prospected, aiming to provide a reference for the development of antitumor drugs in this direction.

BACKGROUND: Practice has proved that organic material and inorganic materials used alone are not ideal scaffold materials. Polylactic acid (PLA) possessing excellent biocompatibility, degradability and absorbability, PLAs composites will be one of the most important biocomposite in the 21~(st) century. OBJECTIVE: To observe the effects of PLA-chitosan fiber (CF)/hydrexyapatite-calcium silicate (HA-CS) on adhesion, proliferation and differentiation of osteoblasts. METHODS: The rat osteoblasts were obtained from the cranium of newborn Wistar rats within 24 hours, and primarily cultured using modified collagenase digestion. The cells were generated and their biological characteristic was examined by inverted phase-contrast microscope, hematoxylin-eosin staining, alkaline phosphatase (ALP) staining and mineralized nodules staining. Then the cells at passage 3 were co-cultured with PLA-CF, PLA-CF/CS and PLA-CF/HA-CS in vitro. At 3, 6 and 9 days of the culture, cell morphology was observed by inverted phase contrast microscopy. In addition, MTT assay and ALP activity test were used to observe the effects of three kinds of materials on cell differentiation and proliferation. RESULTS AND CONCLUSION: Osteoblasts attached on all three scaffold materials can adhere, grow, differentiate and proliferate. The effect of three materials on cell activity was PLA-CF/HA-CS>PLA-CF/CS>PLA-CF. The composite scaffold PLA-CF/HA-CS has a good compatibility, indicating that the material has a great potential for application in bone tissue engineering.

Objective To analyze the characteristics, surgical timing and treatment of middle super thoracic fractures. Methods 35 cases of middle super thoracic fractures (T1 10) were retrospectively reviewed. Among them, 25 cases were complete injury of the spinal cord and 10 cases were neurologically incomplete injury. The bleeding in operations at different times, the ASIA grades and the sensorimotor scores were analyzed. Results The follow up showed that the ASIA grade increased by 1 to 2 degrees in 10 cases of incomplete spinal cord injury, while in complete spinal cord injury the ASIA grades hardly increased but the sense and motion scores could be improved by about 20. Conclusions Middle super thoracic fractures often involve multi vertebra body, and the spinal cord is injured severely. Decompression, fusion, internal fixation from posterior approach can obtain a satisfactory result. Neurologically incomplete injury should be treated as soon as possible, while complete injury of the spinal cord should be treated around 2 weeks after the injury.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. However, due to its complex pathogenesis, there are no officially approved drugs for NAFLD treatment currently. Therefore, it is extremely urgent to find safe and effective anti-NAFLD drugs. Nowadays, lipid-lowering drugs are the main option for NAFLD therapy, but the clinical efficacy of chemical drugs is also very limited, as well as the frequent side effects or adverse reactions. Traditional Chinese medicine (TCM) has attracted more and more attention in the treatment of NAFLD due to its unique advantages through multiple targets and pathways with few side effects. In recent years, numerous studies have demonstrated that the imbalance of gut microbiota plays an important role in the occurrence and development of NAFLD. This review systematically summarizes the experimental and clinical evidences of TCM active compounds and TCM prescription involved in the regulation of intestinal flora in the treatment of NAFLD in recent years, so as to provide a reference for further exploring the pathogenesis of NAFLD and exploring TCM treatment methods.

Streptozotocin-induced diabetic model was prepared in Wistar rats and the blood glucose levels were controlled at 3 levels of＜10,10-14 mmol/L or＞16.7 mmol/L by insulin,and changes of glucose transporter(GLUT)1 and 3 protein expressions of brain were observed in control rats and diabetic rats with different blood glucose levels by immunohistochemistry.The results showed that chronic hyperglycemia could decrease the protein expressions of GLUT 1 and GLUT3.

AIM: To evaluate effects of Pinaverium Bromide on different segments and layers of colonic smooth muscle in wrap restraint stress (WRS) rats and explore its possible therapeutic mechanism on different types of irritable bowel syndrome (IBS). METHODS: Adult SD rats were randomly divided into model group (wrap restraint stress group) and control group. Colonic smooth muscle strips were made from different segments and layers in two groups. The spontaneous contraction activities of colonic longitudinal/circular muscle (LM/CM) strips of rats were observed with organ bath system before and after addition of series concentrations of pinaverium. RESULTS: Pinaverium Bromide caused concentration-dependent inhibition of colonic smooth muscle, the inhibitory effect of pinaverium in model group was significantly stronger than that in control group(proximal colon: 28.54±4.82 vs 7.48±1.65,21.75±1.00 vs 12.56±3.15; distal colon: 15.71±5.27 vs 3.89±1.16, 20.16±3.16 vs 7.56±1.96 )(P<0.05). Compared with that of distal colon, inhibitory effect of pinaverium was significantly higher of proximal colon (P<0.05). For the inhibition of pinaverium, there was no significant difference between LM and CM strips in the same intestinal segments (P>0.05). CONCLUSION: Effects of Pinaverium Bromide on different colonic muscle layers and segments in WRS rats is probably related with its therapeutic mechanism on different types of IBS.
