Andrology and gynecology have a similar or the same theoretical basis in Traditional Chinese Medicine (TCM). Andrology has a history of less than 3 decades in China, while TCM gynecology has developed for over a thousand years. The development of andrology could be greatly promoted with the guidance of the theories and prescriptions of gynecology.

BACKGROUND: A large amount of in vivo and in vitro experiments have confirmed that, basic fibroblast growth factor (bFGF) has been widely utilized in various tissues and cells, it can facilitate the wound healing.OBJECTIVE: To observe the efficacy and feasibility of gene gun-mediate delivery of human bFGF on the healing of deep partial thickness bum wounds.DESIGN, TIME AND SETTING: Randomized design,an observational trial was performed at the Military Central Laboratory of Changhai Hospital in the Second Military Medical University of Chinese PLA between December 2007 and October 2008.MATERIALS: SD rats of clean grade, weighing 200-250 g, irrespective of genders, ware involved in this study.METHODS: Natural human bFGF gene was recombined and optimized, then eukaryotic expression vector pCI-neo-bFGF was constructed taking pCI-neo as a vector, and transfeoted with human embryonic kidney cells 293 T cells. Dot blot and Western blot methods were utilized to determine the bFGF expression. Rat model of deep partial thickness burn wounds was processed into transgene process using gene gun technique, pCI-neo-bFGF-transfected ones served as experiment group while pCI-neo-transfected ones served as controls.MAIN OUTCOME MEASURES:Wound healing time was recorded and the efficacy was evaluated. The contents of hydroxyproline and collaganase Ⅰ in burn wound tissues were determined at 24 hours, 48 hours, 96 hours, 7 days, 10 days and 14 days following transgene process.RESULTS: the recombinant pCI-neo-bFGF was transfected with human embryonic kidney 293T cells. Dot blot and Western blot analysis have showed that, the constructed pCI-neo-bFGF expression vector could express human bFGF, and the expression of synthesized gene was remarkably higher than that of natural gene under fluorescence microscope; gene gun-mediated transgene experiment have showed that, the wound healing time was (13.00+1.31) days in the experiment group and (14.75±1.28) days in the control group, with significant differences (P＜0.05). The contents of hydroxyproline and collagenase Ⅰ reached a peak at 5 days after the injury, that is 48 hours after transfection, and then gradually decreased and maintained at a certain level. The experiment group had higher hydroxyproline levels compared with control group at different time points (P＜0.05, P＜0.01); the collagenase Ⅰ in the experiment group was notably higher than that in the control group at 48 hours and 96 hours after transfection (P＜0.01).CONCLUSION: Gene gun-mediated delivery of human bFGF can short the time of wound healing, increase the contents of hydroxyproline and collagenase Ⅰ during the healing period, accelerate the healing of deep partial thickness burn wounds.

Objective To investigate the effects of pulsed electromagnetic fields(PEMFs)on proliferation and differentiation of endothelial progenitor cells(EPCs).Methods EPCs were isolated from rat bone marrow by density gradient centrifugation.EPCs were exposed to PEMFs from the 5th day to the end of culture.MTT was used to measure the proliferation of EPCs.The expression ofⅧ-related antigen and NOS_3 was evaluated by flow cytometry. Results Compared with the control,the proliferating ability of EPCs exposed to PEMFs was stronger;the number ofⅧ-related antigen and NOS_3 positive cells increased significantly in EPCs exposed in PEMFs.Conclusion PEMFs promotes the proliferation and differentiation of rat bone marrow EPCs.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy combined with limited open repair of medial collateral ligament (MCL) for the treatment of multiple ligament injuries of knee joints.

METHODSFrom March 2006 and June 2012,the data of 14 patients (14 knees) with multiple injuries of ACL, PCL, and MCL were collected. There were 8 males and 6 females with an average age of (31.8 +/- 8.1) years old (ranged, 20 to 49 years old). All the patients were performed with X-ray and MRI examination, and the results showed that 10 patients had combined with injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL); 4 patients had ALC,PCL and posterolateral corner (PLC) injuries. Four patients had medial meniscus injuries and 2 patients had lateral meniscus injuries. The MCL,PLC and meniscus injuries were treated with operation on the first stage, and functional exercises were performed 3 weeks after fixation. The reconstruction operation of ACL and (or) PCL was performed at the second stage under arthroscopy 3 to 6 months later when the movement range of knee joint recovered to the normal level with obvious relaxation.

RESULTSAll incisions healed by primary intention. All the patients were followed up with a mean duration of 48.9 months (ranged, 24 to 80 months). The Lysholm score was improved from preoperative 19.6 +/- 0.9 to the latest follow-up 87.1 +/- 2.8 (t=12.3, P<0.01). The International Knee Documentation Committee (IKDC) rating: 9 cases nearly recovered to normal, 5 cases were abnormal.

CONCLUSIONFor multiple ligament injuries in the knee, staged repair and reconstruction can effectively restore knee joint stability and function.

OBJECTIVETo analyze the consistency of evolution condition between HA gene and the whole genome of influenza virus subtype A/H3N2 strains isolated in Zhejiang province from 1998 to 2009, and to study the potential antigenic region on the whole genome.

METHODSThe sequences of whole genome of 19 Zhejiang influenza virus isolates circulated from 1998 to 2009, which conserved by influenza laboratory of Zhejiang Provincial Centre for Disease Prevention and Control, were amplified using RT-PCR assays. The obtained sequences were used to conduct phylogenetic analysis with 10 contemporaneous vaccine strains. Three methods, including comparison of the amino acid substitutions, calculation of the entropy value and the filtering of positive selection sites, were used to confirm the mutable sites on each gene.

RESULTSThe whole genome of influenza virus subtype A/H3N2 was 4466 amino acids in length, with 137 stable mutations. The 144, 158 aa of HA gene mutate four and three times respectively; 93, 143, 307, 370, 372 aa of NA gene and 450 aa of NP gene mutate twice, and there were 29% (12/41) and 77% (24/31) mutations of HA and NA genes occurred on the non-epitope regions respectively. Analysis of the entropy value suggest that many amino acid sites on the non-epitope regions were prone to mutation, including 3, 225, 361 aa of HA gene; 93, 143, 147, 150, 372 aa of NA gene; 113, 576, 586 aa of PB1 gene; 101,256, 382, 421, 437 aa of PA; 377, 450 aa of NP gene; 218 aa of M1 gene and 31 aa of M2 gene.

CONCLUSIONBased on the whole genome of influenza virus subtype A/H3N2 strains isolated in Zhejiang province in 1998 to 2009, there may be several unknown or new antigen sites existing on the non-epitope regions of HA and NA genes and parts of internal genes. The phylogenetic tree constructed based on the complete sequence was more comprehensive than on the HA gene to reflect the genetic relationship and law of evolution among the influenza virus strains.

Objective To analyze the relationship between influenza epidemic and genetic characteristic on the whole genome of influenza virus subtype A/H3N2 strains isolated in Zhejiang province during 1998 to 2009. Methods All of the eight genes from the 19 Zhejiang influenza virus isolates, circulated during 1998 to 2009, were amplified by RT-PCR and sequenced. The obtained sequences were aligned and analyzed with the vaccine strains being used in the last 10 years.Results The highest mutation happened within HA and NA genes and the amino acid divergent ratios were 13.98% and 10.00%. Amongst the six internal proteins, the amino acid divergent ratios of NP, M2 and NS1 were 6.43%, 6.19% and 3.48% respectively, and the others were lower than 3%.Other than the HA and NA genes, mutations were also observed on six internal genes of the strains isolated in those years when the influenza virus subtype A/H3N2 was widely circulating.Additionally, there had been an obvious genetic lag between vaccine strains recommended by WHO and the contemporary Zhejiang epidemic strains for many years. Conclusion Besides on HA and NA genes, surveillance programs should also be covered mutations regarding the internal genes of influenza virus subtype A/H3N2 strains, in order to provide important information for forecasting and warning of a new round of influenza epidemic.
