Objective: To compare tea polysaccharides(TPS) characteristics and their role in scavenging free radicals and reducing blood glucose(BG) in diabetic mice(DM). Methods: TPS was extracted from green,Oolong and black tea which were made from the same fresh leaves from Hubei,Fujian and Yunnan. Then the recovery rate of TPS, contents of neutral sugar, uronic acid and protein were analysed, and scavenging rate of -2Oand 稯H in vitro and hypoglycemic effect were also determined. Results: 1. The yield and contents of neutral sugar, uronic acid and protein of green tea TPS were the highest, and those of black tea TPS were the lowest. Oolong tea TPS acted the best in scavenging-2O and 稯H . 2. The hypoglycemic effect of TPS from Hubei tea was the best . The effect of TPS extracted from semi-fermented Oolong tea and fermented black tea was better than that of non-fermented green tea. 3. There were obvious differences in yield, free radical scavenging rate and effect of reducing BG among TPS extracted from tea in different regions. TPS extracted from Fujian tea had the best effect in reducing BG,but that from Yunnan tea had not. Conclusion: There was remarkable effect of region and process on physico-chemical characteristics,effect of scavenging radical and reducing blood sugar TSP.

Using 16S rDNA clone library method, the bacteria composition of the Organic Matter-decomposing Inoculants A and B were investigated. The results indicated that: Sample A was clustered into 14 taxonomic operational units (OTUs),the dominant communities are Weissella confuse, Bacillus subtilis and Bacillus pumilus, which accounted for 28.6%,30.4% and 23.2%;Sample B was clustered into 43 OTUs,the dominant communities are Lactobacillus buchneri, Lactobacillus farciminis and Lactobacillus acetotolerans, which accounted for 18.03%,18.86% and 13.12%, respectively. The results had much difference from the samples' labels:there were not bacteria in the lable of sample A and only Bacillus pumilus was the same with the lable of sample B.This study showed that 16S rDNA clone library method has nicer application perspectives in analying the bacteria of microbial inoculant and its quality control.

Abstract: Objective　To investigate whether the complement system of COVID-19 is affected by vaccination, and also to explore the relationship between complement and length of stay in hospital, with a view to providing input for clinical diagnosis and the management of COVID-19 patients. Methods　The patients admitted from November 1st to November 30th, 2021 in the Eighth Affiliated Hospital of Guangzhou Medical University were selected as subjects. According to the time of vaccination, the patients were divided into two groups as vaccinated within half a year and over half a year. Then C3, C4, IgG, IgM, IgA, COVID-19 IgG and IgM, neutral granulocyte and lymphocyte count were detected and all patients' hospitalized days were recorded. With their hospitalization days of 14 d as a threshold, the patients were divided into two groups, and the above indicators were compared. Results　C3 concentration was (0.86±0.157) g/L in patients with vaccination within six months, which is significantly lower than (0.96±0.172) g/L in those over six months (P<0.05), but as for C4, IgG, IgM, IgA, COVID-19 IgG and IgM, neutral granulocyte and lymphocyte counts, there were no significant difference between two groups; as for the patients within 14 days of hospitalization, C3 and C4 concentrations were lower than those for more than 14 days, but the COVID-19 antibody IgG and IgM, lymphocyte counts were higher (all P<0.05). Conclusion　Vaccination within half a year can make the body's immune function and complement system to identify viruses earlier, more beneficial to remove viruses, but this effect is weakened after half a year; when admission, C3, C4, COVID-19 IgG level and lymphocyte counts can be used to predict hospitalization time in COVID-19 patients.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

Objective To study the expression and the relation of vascular endothelial growth factor (VEGF)and matrix metal proteinase-2(MMP-2)in rectal cancer and evaluate their roles in rectal carcinogen- esis and development.Methods The expression of VEGF and MMP-2 in 52 cases of rectal cancer was de- tected by immunohistochemical SP technique.12 cases normal rectal tissue served as the control group.Re- suits The expression of VEGF in rectal carcinoma(67.3 %)was much higher than that in control group(P
