BACKGROUND:The blood supply is essential for the repair of the meniscus after the suture of it in the injured knee joint. According to the condition of blood supply, the meniscus was divided into three zones by Arnoczk in 1982. The absolute vascularization zone, in which the distance to the combination part of meniscus and synovial membrane is inferior to 3mm, is called the red zone. The absolute devascularization zone, in which the above-mentioned distance is superior to 5 mm, is called the white zone.And the relative vascularization zone with the distance between 3 mm to 5mm is called red-white zone.OBJECTIVE: To observe and discuss the anatomical features of the blood supplyof the meniscus.DESIGN:Single sample observation.SETTING:Department of Orthopaedics, Huaxi Hospital of Sichuan University.PARTICIPANTS: The study was conducted in Huaxi Hospital of Sichuan University during the period from September 2000 to March 2001.Nineteen cases were collected, including 19 knees (38 menisci) from the subjects, 17 male and 2 female, whose age varied from 21 to 43 years old.All the samples were obtained in the amputation operation, the isolated limbs were without the change of re-transplantation and the voluntary donations from the non-minorities living in Sichuan.meniscus samples: 7 knees (14 menisci) were taken. After the femoral artery intubation and infusion of the heparinized normal saline, the vascular bed had no blood and then was infused with the normal saline and ink of 0.5 volume fraction and the infusion pressure was 13 kPa. The infused meniscus samples underwent the dehydration of gradient ethanol,the transparency of dimethylbenzene, and preservation with ilex pedunculosa, and then the blood supply of the menisci was observed and distribution of the meniscus section: 6 knees (12 menisci) with fresh and uninfused menisci were taken. The sections obtained at the sagittal plane,the coronal plane and the horizontal plane underwent hematoxylin-eosin staining. Then the tissues structure and blood supply of the meniscus samples were observed with light microscope. Another 6 knees (12meniscus) underwent the specific CD34 antibody immunohistochemical staining. Then the tissue structure and blood supply distribution of the meniscus samples were observed with the light microscope.in the devascularization zone of the meniscus.RESULTS: Nineteen cases with 38 menisci all went into the final result resourced from the medial and lateral genicular arteries and the middle genicular artery. The small vessels from them form the peripheral capillary vessel plexus and annular vessel meshwork in the synovium and joint capsule and then go into the menisci for the nutrition of the lateral The apparent lunar artery is sent by the vessel plexus around the meniscus into the body of the meniscus and arranges in the inferior,middle and superior layers and dominates 25%-30% of the zone around The vessels of the angular part of the semilunar plate cover the whole meniscus. The nutrition is supplied by the membranous synovium on the surface of the meniscus.Rich blood supply was observed in the anterior and posterior angular laminated blood supply in the body of the meniscus was newly devascularization zone of the meniscus is supplied from the joint synovial fluid is explicit.

Objective To investigate the effect of low dose radiation on the expression of p16 gene in chronic myelogenous leukemia.Methods Leukemic stem cells(LSCs)which expressed CD34+,CD38- and CD123+ were isolated from bone marrow cells obtained from twenty patients newly-diagnosedas chronic myeloid leukemia with EasySepTM magnet beads.Hematopoietie stem cells(HSCs) which expressed CD34+ and CD38- were isolated from human cord blood cells obtained from twenty full-term deliveries with EasySepTM magnet beads as control.HSCs vs LSCs samples were further divided into three dose groups,including 0,12.5 and 50 cGy,respectively.RT-PCR and real-time quantitative reverse transcription-polymerase chain reaction methods were used to detect mRNA expression of p16 gene in HSCs and LSCs after irradiation.Cells were harvested at different time for detection of cell cycle and apoptosis by flow cytometer.Results p16 mRNA level in CML-LSCs was increased slightly at 12.5 cGy,and significantly increased at 50 cGy(Z=-3.39,P<0.01),but ho significant change was found in HSCs.The percentage of CML-LSCs cell in G0/G1 stagewas increased 48 h after 12.5 cGy irradiation,and 72 h post-irradiation with 50 cGy.The apoptosis rate of CML-LSCs was gradually raised after LDR,especially at 72 h post-irradiation of 50 cGy[(17.75±11.76)%vs(6.13±4.71)%,Z=-2.37,P<0.01 ].Conclusions p16 gene transcription could be up-regulated by low dose radiation,which might provide a theoretical evidence for CML therapy and LDR in leukemic clinical application.

Drugs for the treatment of premature ejaculation (PE) are divided to two categories: oral drugs and local drugs. Oral drugs include antidepressive drugs, alpha-adrenoceptor blocking drugs, phosphodiesterase type V blocking drugs and Chinese herbal medicine. Local drugs include local surface drugs, intracavernosal injective drugs and local urethra drugs. Antidepressive drugs are extensively used, which have moderate efficacy, relatively more side effects and high recurrence rate; alpha-adrenoceptor blocking drugs are seldom used and are less effective than antidepressive drugs; phosphodiesterase type V blocking drugs like sildenafil have good efficacy and few side-effects and are worthy to be studied further. Local surface drugs like SS-Cream have good efficacy and few side-effects and are worthy to be applied and promoted; local urethral drugs like MUSE and Befar may become a new method to treat PE after being further studied. Medication for premature ejaculation shall be made specific and suitable as much as for each individual patient.

The highly-pathogenic EV71 strain is the primary cause of mortality in hand-foot-and-mouth disease (HFMD) associated with neurological symptoms, for which no clinically effective drugs or vaccines exist. This study aimed to construct infectious cDNA clones of the EV71 highly-pathogenic strain and the cell-culture adapted strain using a reverse genetics approach. The genomic RNAs of EV71 parent strains were used as the templates for RT-PCR amplification, and then the PCR products that overlapped the full-length genome were connected into the pBR322 vector to produce infectious clones of pEV71 (HP) and pEV71 (CCA), respectively. The results showed that the HP strain propagated much more quickly than the CCA strain. The rescued viruses derived from the infectious clones not only maintained their consistency with their parent strains in terms of genomic sequences, but also retained their respective biological phenotypes. This research will contribute to our understanding of EV71 pathogenesis and the development of novel vaccines against HFMD.

With the emergence of drug resistant tuberculosis, it is very urgent to find novel anti-tuberculosis drugs, especially novel anti-drug-resistant tuberculosis drugs. Because of the slow growth and the need to work in a biosafty environment of Mycobacterium tuberculosis, the development of evaluation of drug effect is severely impeded. In order to solve these issues, non-pathogenic fast-growing Mycobacterium smegmatis is introduced as test organism. The inhA is one of a target of isoniazid (INH) overexpression or mutation of this gene in Mycobacterium tuberculosis conferring resistant to INH. A recombinant plasmid bearing inhA was constructed and electroporated into Mycobacterium smegmatis, using shuttle expression vector pMV261. Transformants were induced to express a protein of inhA, identified by SDS-PAGE. Results show that Mycobacterium smegmatis containing inhA plasmids exhibited 100-fold or greater increased resistance to INH, but it conferred no increased resistance to others first-line anti-tuberculosis drugs. Resazurin microtiter assay plate testing of Mycobacterium smegmatis susceptibility to drugs is a rapid, simple, and inexpensive method and could decrease color background of drugs by detecting fluorescence. It will be benefit for high-throughout screening of drugs of anti-isoniazid-resistant Mycobacteria.
