Forest musk deer is one of the large-scale farming musk deer animals with the largest population at the same time. The male musk deer can secrete valuable medicines, which has high medicinal and economic value. Due to the loss of habitat and indiscriminate hunting, the numbers of wild population specie and the distribution have been drastically reduced. Therefore, in-depth understanding of the molecular genetics progress of forest musk deer will pave a way for musk deer protection and breeding. In this review, the progress associated with the molecular marker, genetic classification, artificial breeding, musk secretion and disease in past decades were reviewed, in order to provide a theoretical basis for subsequent molecular genetic researches in forest musk deer.

OBJECTIVETo investigate the expression of alpha-melanocyte-stimulating hormone (alpha-MSH) in human split-thickness skin autograft and the role of alpha-MSH in hyperpigmented process of the grafted skin.

METHODSImmunohistochemical technique was used to detect the expression and distribution of alpha-MSH in the split-thickness grafted skin and normal skin separately.

RESULTSThe expression of alpha-MSH in most of the split-thickness grafted skin was much stronger than the control skin. The positive ratio of alpha-MSH expression was 61.1% in the split-thickness grafted skin, 11.1% in the normal skin of the donor area and 16.7% in the normal skin around the recipient area. The expression of alpha-MSH in the split-thickness grafted skin was significant high, compared with the normal skins (P < 0.01). The expression of alpha-MSH in the normal skin of the donor area was no statistic remarkably differences compared to the normal skin around the recipient area.

CONCLUSIONThe results indicate that the expression of alpha-MSH may markedly increase in the split-thickness grafted skin and correlate with its pigmentation after the skin graft. Overexpression of alpha-MSH may play an important role in hyperpigmented process of the skin graft.

Aim To investigate the effect of TaorenHonghua drug pair on intervertebral disc degeneration (IVDD) in rats.Methods Fifty healthy Wistar rats were randomly divided into control group,model group,sham group,meloxicam group and Taoren-Honghua drug pair group,with 10 rats in each group.We established dynamic and static forces imbalance of cervical disc degeneration model or sham surgery in rats.12 weeks later,rats were intragastrically administered with meloxicam,Taoren-Honghua drug pair or saline for 30 days.C4/5 and C6/7 discs were harvested from rats.ABOG staining was used for observation of intervertebral disc morphology,real time PCR for mRNA expressions of type Ⅱ collagen (Col Ⅱ) and type Ⅹ collagen (Col Ⅹ),and immunohistochemical staining for Col Ⅱ and Col Ⅹ.Results Compared with model group,Col Ⅱ expression increased,while Col X expression decreased in chondrocyte of intervertebral disc in Taoren-Honghua-treated group(P ＜ 0.01).Conclusion Taoren-Honghua drug pair could delay the degeneration of cartilage endplate in rat intervertebral disc.

Objective To report a large family with an autosomal dominant dementia associated with mutation in the prion protein gene(PRNP)and the detailed clinical,neuroimaging and pathological manifestations.Methods Two patients from a large family of dementia were admitted to our ward and the data of their medical history,physical examination,video electroenceplialogram,neuroimaging were colleted.A sterotactic biopsy of the right frontal lobe of the proband was done.After the informed consent from the family members obtained,the genomic DNA was extracted from peripheral blood leucocytes of 5 persons followed by in,vitro amplification using polymerase chain reaction(PCR).The PCR products were directly sequenced by Sanger method.PRNP gene sequence was also examined in 150 normal Chinese to exclude single nueleotide polymorphism.Results A missense mutation of PRNP gene in 5 farnily members was detected,resulting in Gll4V mutation in the prion protein,with M/M genotype of eodon 129.This mutation was not detected in 150 normal Chinese.The proband was diagnosed as inherited prion disease by her clinical features,including neuropsychiatrie disturbances and progressive dementia,and manifestations of neuroimaging,EEG,neuropathology and PRNP gene mutation.Conclusion The first autosomal dominant pedigree of family prion disease is found in China with G114V mutation in PRNP gene which may lead to the prion disease directly.

OBJECTIVETo observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI).

RESULTSAfter treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05).

CONCLUSIONThe yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.

OBJECTIVETo study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

METHODSTwenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.5 years old. The duration from injury to surgery ranged from 2 hours to 2 months, and the mean time was 6 days. All the patients had collateral ligament injuries combined with fracture of the metacarpophalangeal joint of the thumb. Thirteen patients had injuries in the right hand and 9 patients had injuries in the left hand. There were 18 cases of closed wound and 4 cases of open wound. Eighteen patients had fresh injuries (< 2 weeks) and 4 had old injuries (> 2 weeks). Sixteen patients had injuries in the ulnar collateral ligament of the thumb combined with fracture, 6 patients had radial collateral ligament injuries of the thumb combined with fracture, 4 cases of which were complicated with injuries of abductor pollicis brevis and the end of the flexor pollicis brevis tender. The size of the avulsed fragment was about 3.0 mm x 4.0 mm to 6.0 mm x 7.0 mm.

RESULTSThe incisions of 22 patients healed by first intention. The follow-up periods ranged from 6 months to 5 years old,with an average of 2.5 years old. The thumb function was evaluated by Saetta and other evaluation criteria, and 20 patients got an excellent result and 2 good.

CONCLUSIONThe application of one-hole microplate internal fixation in treating collateral ligament injuries with fracture of the metacarpophalangeal joint of the thumb is an effective method.
