The origin and development of umbilical therapy in traditional Chinese medicine is explored from related literature in the history. As a result, the Shang period is regarded as initial period of umbilical therapy, while periods from Han Dynasty, Jin Dynasty and Southern-Northern Dynasties to Sui Dynasty and Tang Dynasty could be taken as stage of primary development. Time from Song Dynasty, Jin Dynasty and Yuan Dynasty to Ming and Qing Dynasties is believed as mature stage. Also the manipulation, application principle, indications and contraindications of umbilical therapy are explained. A brief overview of modern development of umbilical therapy is also described.

AIM: To investigate the pharmacokinetic properties and bioequivalence of nifedipine sustained-release tablets after multiple doses administration in healthy volunteers. METHODS: Twenty two male healthy volunteers were enrolled in a randomized two-way crossover design with multiple doses (20 mg·d-1×7 d) study. Nitrendipine was used as the internal standard and the concentrations of nifedipine in plasma were determined by HPLC-APCI-MS. The pharmacokinetic parameters were calculated and the bioequivalence were compared by DAS (ver 1.0) program. RESULTS: The pharmacokinetic parameters of test and reference preparations were as follows: Cmax (52.5±27.4) and (54.0±31.2) ng·ml-1;Cmin (5.4±4.1) and (6.2±5.9) ng·ml-1;Cav (16.8±9.2) and (19.3±12.4) ng·ml-1;Tmax (3.7±0.9) and (4.1±1.1) h;t1/2 (8.9±4.9) and (8.5±3.1) h;AUC0-τ (403.4±221.0) and (461.9±296.6) μg·h·L-1, AUC0-36h (444.4±256.1) and (503.1±330.9) ng·h·ml-1;AUC0-∞ (482.1±268.9) and (542.3±348.4) ng·h·ml-1;DF (299.8±117.7)% and (279.2±97.5)%, respectively. There were no significant differences (P>0.05) in Tmax, Cmax, Cmin, Cav, DF, AUC0-τ, AUC0-36h, AUC0-∞ and t1/2 between the two preparations. The relative bioavailability of test tablets was (100.6±38.6)%. CONCLUSION:The test and reference preparations were bioequivalence.

Objective To investigate the relative factors of insulin resistance(IR)during elective abdominal surgery and the mechanism of IR induced by surgery.Methods Fourteen patients underging elective abdominal surgery were studied.Fasting blood glucose(FBG),fasting plasma insulin(FPI),plasma TNF-α,IL-6 and CRP were tested for elective surgery patients on the day before,during operation and on one day after surgery.Insulin resistance index(HOMA-IR)and the index of insulin secretion(HOMA-β)were ealculated with homeostasis model assessment(HOMA).Insulin receptor and GLUT4 mRNA expression in skeletal muscle were assessed before operation and at the end of operation by use of RT-PCR.Results Significant differences were found in fasting blood glucose (5.95±1.08)mmol/L vs(8.92±2.41)mmol/L,fasting plasma insulin(19.95±3.33)mU/L vs(25.44±5.36)mU/L,IL-6(33.98±5.01)ng/L vs(45.29±7.81)ng/L and plasma TNF-α(86.70±9.27)ng/L vs(114.46±15.33)ng/L during and after operation(P＜0.01).A significant elevation of HOMA-IR levels was found after operation compared with that before operation[(9.59±2.89)vs(4.111.86)](P＜0.001).However there wag no significant difference in HOMA-β among three points(groups)of time(P=0.103).The result of RT-PCR showed that the expression of GLUT4 in muscle of patients at the end of operation reduced significantly compared with preoperation(t=12.488,P＜0.001)but there was no significance in INSR mRNA expression(P=0.165).ISI showed negative correlation with opermive time(r=-0.736、P＜0.001),blooding during operating (r=-0.594、P=0.032)and post-operative TNF-α(r=-0.641、P=0.018).Conclusion Insulin resistance occurs in elective abdominal surgery patients.The defective site is at postreceptor.To shorten the operation time,control the intensity of surgery and reduce the bleeding is helpful for decreasing IR.

Objective:To compare the efficacy and safety between direct anterior approach (DAA) and posterior approach (PA) in total hip arthroplasty.Methods: This study evaluated postoperative results of 92 consecutive total hip arthroplasties performed by a single surgeon;44 from the DAA,and 48 from PA.The age,body mass index,operation time,blood loss,hospital stay,positioning of the artificial hip,postoperative Harris score and postoperative complications were recorded and analyzed.Results: Both the average age of the patients separately (58.0±11.9) years in DAA group and (61.0±10.4) years in PA group and the body mass index (25.1±3.7) in DAA group and (24.7±3.3) in PA group,showed no significant difference between the two groups.The DAA group had significantly reduced the hospital stay (3.8±1.7) days vs.(4.9±2.3) days for the PA group (P<0.05) and operation time was (76.0±17.4) min in DAA group,and (71.0±14.3) min in PA group (P>0.05).The amount of blood loss: in group DAA (238.0±55.3) mL,and in group PA (387.0±61.2) mL (P<0.05).There was no statistical difference in the positioning of the artificial hip: the cup anteversion in DAA group and PA group was 17.3°±5.3° vs.18.6°±5.1°,the cup inclination was 38.5°±5.7° vs.37.7°±5.2°.In DAA group,there was significantly less use of assistive devices [(24.6±7.8) d vs.(31.7±10.2) d,P<0.05],and the pain was significantly lower.Harris score at the end of 6 weeks of the follow-up: in DAA group 85.7±5.4,and in PA group 81.3±6.1 (P<0.05);at the end of the last follow-up: in DAA group 93.4±4.7,and in PA group 92.3±5.3 (P>0.05).Complications were encountered in the two groups.There were two intraoperative complications (4.4％),1 great trochanter fracture and 1 lateral cutaneous nerve injury in DAA group.No dislocation was observed in DAA group.One dislocations and 1 groin pain were recorded in PA group.No prosthesis loosening,deep vein thrombosis,sciatic nerve injury and other complications occurred in the two groups.Conclusion: Total hip arthroplasty using the anterior approach allows for superior recovery and better stability.

Abstract: Objective　To analyze the distribution characteristics of the main pathogens of HIV/AIDS patients with wound infections and provide basis for clinical diagnosis and treatment. Methods　The clinical data of 294 patients with positive secretions or pus specimens from 2016 to 2020 were analyzed retrospectively. Results　A total of 357 strains of pathogenic bacteria were isolated from 294 cases, of which 123 strains of Gram-negative bacilli (G-b), accounting for 34.5%, were mainly Escherichia coli (15.4%), Klebsiella pneumoniae (3.9%), and Pseudomonas aeruginosa (3.6%); Gram-positive bacilli (G+b) 14 strains, accounting for 3.9%; 108 Gram-positive cocci (G+c), accounting for 30.3%, of which 44 strains were coagulase-positive Staphylococcus aureus (12.3%), Coagulase-negative staphylococci were mainly Staphylococcus epidermidis (4.2%) and Staphylococcus hemolyticus (2.8%); 37 strains of fungi, accounting for 10.4%, were mainly Candida albicans (5.9%); 75 strains of Mycobacterium, accounting for 21.0%, including 41 strains of Mycobacterium tuberculosis (11.5%) and 34 strains of non-tuberculosis mycobacteria (9.5%). 52 of the 294 HIV/AIDS patients had mixed infections, accounting for 17.7%. There was significant difference in the distribution of G+c, G-b, mycobacteria and mixed infection among different specimen sources (P<0.05), and there was significant difference in the distribution of mycobacteria among different CD4+T lymphocyte counts (P<0.05). There was significant difference in the level of CD4+T lymphocytes between patients of different ages (P<0.05), and there was significant difference in the level of CD4+T lymphocytes from postoperative incision and other parts (P<0.05). Conclusions　Patients with HIV/AIDS are prone to combined wound infections with various pathogenic bacteria. We should strengthen the research on wound infection in HIV/AIDS patients, and timely send patients with a low number of CD4+T lymphocytes for secretion or pus culture, so as to carry out targeted treatment and improve the prognosis of patients.
