Objective To observe skin test results of tetanus antitoxin prepared by different solvents.Methods Patients who needed injecting tetanus antitoxin as required by trauma were randomly divided into two groups, Group A and Group B, respectively. Group A was administered with tetanus antitoxin prepared by water for injection, while Group B with tetanus antitoxin prepared by saline. Skin test results were observed, the incidence of positive skin test results and self-inductance of pain intensity were compared.Results The incidence of positive skin test results in Group A was significantly higher than that in Group B (34.19% vs 17.50%,χ2=8.631,P<0.01), and the self-inductance of pain intensity were also greater than that in Group B. Patients with positive skin test results (40 patients) in Group A, were later injected tetanus antitoxin prepared by saline, 42.50% of them (17 patients) shown negative skin test results.Conclusions There might be a high false positive rate by using tetanus antitoxin prepared by water for injection; therefore tetanus antitoxin prepared by saline is recommended, for it could decrease the false positive rate, reduce unnecessary desensitization injections, alleviate patients' pain and improve nurses' work efficiency.

OBJECTIVETo study the role of the synchronized springy lengthening apparatus for the tibia and calcaneal tendon designed by the author in preventing the clubfoot of secondary to the Ilizarov tibia lengthening.

METHODSBased on the Ilizarov tibia lengthening apparatus, a special synchronized springy lengthening apparatus for the tibia and calcaneal tendon was designed. The tibial was made of distal and proximal 2 rings respectively and 4 threaded rods, and the calcaneal was made of a half ring, 2 hinges and a threaded rod with spring. The half ring was fixed to the calcaneus by 2 crossed wires. The fracture tibia and fibula, ankle joint, talocalcaneal joint were attached to the apparatus. At the same time of tibia lengthening, the soft tissue was simultaneously stretched, the ankle joint could move, and the leg could bear weight. If the clubfoot angle was larger, the percutaneous fasciotomy of calcaneal tendon was performed; if the angle was less than 20 degrees, the pes deformities were corrected only by the stretch of calcaneal tendon.

RESULTSSeventy-seven patients' tibia were lengthened averagely 4.6 cm, with an average speed of 0.7 mm/d. The healing made tibia lengthened, and the index was 1.35 months/cm. There were not the secondary varus and valgus deformities and clubfoot in all the patients. The clubfoot with 100-400 angle of the 16 patients were corrected after tibia lengthening.

CONCLUSIONSThe new apparatus coincides with the biomechanical principle and can effectively prevent the secondary deformities of foot such as clubfoot, talipes varus and valgus after tibia lengthening procedure.

Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.

OBJECTIVETo study the relationship between the serum levels of adipocyte fatty acid-binding protein (A-FABP) level and type 2 diabetes mellitus in a community population.

METHODSA total of 255 residents (aged 45-85 years) were randomly selected from 4 communities in Guangzhou to examine the fasting plasma glucose (FPG), 2-hour postprandial blood glucose (2hPG), glycosylated hemoglobin (HbA1c), body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), blood pressure (BP), triglyceride (TG), cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). The insulin resistance index (HOMA-IR) was calculated and enzyme-linked immunosorbent assay (ELISA) was used to determine serum A-FABP and fasting insulin (FINs) levels. The cases were divided into 3 groups according to blood glucose level, namely the normal group (group A, n=90), impaired glucose tolerance group (group B, n=85), and diabetic group (group C, n=80), and the A-FABP levels were compared between them.

RESULTSCompared with group A, the subjects in groups B and C showed significantly increased FPG, 2hPGh, HbA1C, HOMA-IR, systolic blood pressure (SBP), and waist circumference (P=0.000) as well as FINs, WHR, diastolic blood pressure (DBP) , TG, and HDL-C (P=0.038, 0.047, 0.01, and 0.046, respectively). Compared with group B, group C showed significantly higher FPG, 2hPG, HbA1c, TG, and SBP (P=0.00), with also higher levels of FINs, BMI, WC, DBP, and HDL-C (P=0.012, 0.006, 0.03, 0.019, and 0.029, respectively). A-FABP increased significantly in the order of group A, B, and C (P=0.00), and this result was not affected by the differences in age between the 3 groups (P>0.05). A-FABP level was positively correlated to FPB, 2hPG, FINS, WHR, BMI, WC, SBP, and HOMA-IR, but inversely to TG and HDL-C (P=0.00).

CONCLUSIONElevated serum A-FABP is closely related to glucose metabolism disorder, and A-FABP may serve as a useful marker for the occurrence and development of type 2 diabetes in the community population.

OBJECTIVETo investigate cyclooxygenase-2 (COX-2) expression and its relationship with mismatch repair (MMR) protein expression and microsatellite instability (MSI) in hereditary nonpolyposis colorectal cancer (HNPCC).

METHODSA total of 28 cases of colorectal adenoma and 14 cases of colorectal carcinoma were collected between July 2003 and July 2007 from 33 HNPCC families. Sporadic colorectal adenoma (n=32) and carcinoma patients (n=24) served as controls. With samples of tumor tissues and normal colonic mucosa collected from the patients, the protein expressions of COX-2 and MMR (hMLH1, hMSH2, and hMSH6) were examined with immunohistochemical assay. Frequency of MSI in five standard MSI loci BAT25, BAT26, D2S123, D5S346, and D17S250 were analyzed by means of polymerase chain reaction.

RESULTSThe rate of COX-2 high-expression was 53.6% (15/28) and 42.9% (6/14) in HNPCC adenoma and carcinoma; 62.5% (20/32) and 91.7% (22/24) in sporadic adenoma and carcinoma, respectively. That rate was lower in HNPCC carcinoma than in sporadic carcinoma (Pü0.05). MMR-deletion rate and percentage of high-frequency MSI (MSI-H) in HNPCC carcinoma were higher than those in sporadic colorectal carcinoma [both 71.4% (10/14) vs. 12.5% (3/24), both Pü0.01]. Among the 10 MMR-deficient HNPCC carcinoma patients, COX-2 low-expression was observed in 8 cases (80.0%), while COX-2 high-expression was observed in all of the 4 MMR-positive HNPCC carcinoma cases (Pü0.05). In comparison to MMR positive HNPCC carcinoma, HNPCC adenoma, and sporadic carcinoma, COX-2 expression was significantly lower in corresponding MMR-deficient cases (all Pü0.05). The rates of COX-2 low-expression in HNPCC adenoma, HNPCC carcinoma, and sporadic carcinoma with MSI-H were significantly higher than those in the cases with microsatellite stability (all Pü0.05).

CONCLUSIONCOX-2 is expressed at a low level in HNPCC carcinoma, different from the high COX-2 expression in sporadic carcinoma.
