The m. extensor hallucis brevis and m. extensor digitorum brevis and their blood vessels and nerves of 30 feet of Chinese cadavers are observed and measured under the operative microscope. A. tarsea lateralis and the lateral branch of nervus peroneus profundus are the best choice as the pedicle of the musculo-cutaneous flaps at dorsalis pedis. According to necessities the size of muscle may be detected randomly from medial to lateral.

OBJECTIVE To investigate the risk factors of hospital infection among parturients to put forward prevention measures.METHODS The infection cases among parturients in our hospital 2005-2007 were analyzed by retrospective survey.RESULTS The first three infections sites were upper respiratory tract(29.79%);surgical incision(28.72%) and urinary tract(21.28%).The main factor for upper respiratory tract infetion was the traditional postnatal recovering modality.Surgical incision infections were mainly perineum ones.Catheterization after the caesarean operation led to urinary tract infection.CONCLUSIONS Postnatal recovery by scientific modality,aseptic operation and strict infection management are the keys to preventing obstetrical infections.

BACKGROUND: The target gene cannot be deleted at specific time by using conditional gene knockout system. Most gene knockout animals cannot survive during embryonic development and after birth, which limits the study of gene function.
OBJECTIVE: To review the recent advances about time-specific gene knockout technology.
METHODS: An online search in PubMed was performed from the initial stage of database establishment to August 2014. The key words were gene knockout, inducer and Cre/loxP system. The repeated experiment and unrelated articles were excluded during primary search. A summary was made by analyzing time-specific gene knockout technology.
RESULTS AND CONCLUTION: Most important gene knockout animals could not survive after birth, or die at early embryonic stage due to serious physical defects induced by an important gene deletion. Therefore, the progress in the functionality of a gene at a particular time, the genetic characteristics of an individual organism in a particular developmental period, and the treatment of certain acquired disease at a given time have been limited because of the limitations of research methods. However, the occurrence of conditional gene knockout animals, especial y time-specific knockout animals, provides a research model for the study of these areas. This study reviewed the recent advances, development and application about time-specific gene knockout animals, and discussed the significance and broad prospects of time-specific gene knockout technology of specific genes in the field of scientific research.

The blood vessels and nerves of the sole skin of 50 feet of Chinese adult cadavers were observed with an operative microscope. The blood supply of the central part of the sole comes mainly from the medial and lateral plantar ar teries (MPA and LPA). Their average diameter is larger than 2.0mm and their trunk is usually longer than 80mm. When a skin flap is designed, the cutaneous branches from LPA are much better than those from MPA so far as the number of the branches, their external diameter and the extent of the distribution are considered.When the sole skin is stripped away, the cut ends of the cutaneous arteries present a multiple dot-like appearance on the surface of the superficial fascia. The external diameter of the arterial branches, the number of the branches in an unit area, and the total area of the cross section of the branches are different among the regions of the heel and the metatarsal heads, and the central part of the sole. They vary with the weight born on each region.All the cutaneous arteries of the sole are accompanied with veins respectively. Most of the MPA and LPA are accompanied with two veins with a diameter larger than 1.9mm on average. The two veins terminate by joining into two posterior tibial veins.

Objective To observe the effects of misoprostol on the reduction of postpartum bleeding in cesarean section.Methods With oxytocin as control,the amount of bleeding during and two hours after cesarean section was observed.Results The mean amount of bleeding was (232.0±46.6) ml in misoprostol group and (385.0±74.7) ml in oxytocin group respectively.The difference between the two groups was significant (P＜0.01).Conclusion Misoprostol is more effective to improve uterin contraction than oxytocin and is better in the reduction of postpartum bleeding with safety and convenience.

Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on angiogenesis and Ang-1/Tie-2 expression after focal cerebral ischemia in mice. Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion. BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day. The neurological score and the corner test were used to evaluate sensorimotor function during 28 days after ischemia. The microvessels density and the expression of Ang-1/Tie-2 in the ischemic boundary zone were determined by immunohistochemistry on 28 days after ischemia. Results Compared with the model group, BYHWD significantly ameliorated neurological dysfunction and reduced the number of right turn during 3 to 28 days after ischemia(P＜0.05 ). In addition,the numbers of CD31 ,Ang-1 and Tie-2 immunopositive cells were (437 ±59) ,(389 ±61 ) and (251 ±42) at the boundary zone in model group 28 days after ischemia,respectively. However, BYHWD treatment significantly increased the numbers of CD31(609 ± 68 ), Ang-1 (551 ±66) and Tie-2 (342 ±46) immunopositive cells(P＜0. 01 ). Conclusion BYHWD promotes angiogenesis,which may contribute to recovery of neurological function after focal cerebral ischemia,and Ang-1/Tie-2 pathway appears to mediate BYHWD-induced angiogenesis.

Objective To assess the clinical efficacy and safety of testa triticum tricum purif (trade name: fiberform) in treating constipation during pregnancy. Methods With multicenter,prospective and self-controlled study method, in four domestic hospitals 140 pregnant ladies with constipation were enrolled according to recruiting criteria. The patients were treated by orally taking Festa Triticum Tricum Purif 3. 5 g every time, twice a day. Before and after taking medicine,constipation symptoms and the characters of feces were observed and quantized with score to identity its efficacy and side effects. Results After Testa Triticum Tricum treatment, dyporsia was relieved and the characters of the feces were improved significantly. Taking Testa Triticum Tricum for 7 days and 14 days, the effective rate was 90.0% and 93.6% respectively. Before and after taking medicine,the difference in constipation symptoms was statistical significant. No side effects were observed during Testa Triticum Tricum Purif treatment. Conclusions Fiberform is effective and safe for functional constipation treatment.

Background and Objective Large randomized controlled trials have demonstrated that percutaneous coronary intervention (PCI) with the routine use ofdrug-eluting stents is safe and effective, however, the patients older than 75 years undergoing PCI are at increased risk for major adverse cardiac events, so that the patients are usually excluded from this trial. The aim of the present study was to assess the early clinical outcome and risk factors in old patients with acute ST elevation myocardial infarction (STEMI) following primary PCI. Methods We analyzed the outcome after stenting in 136 patients older than 60 years in our coronary care unit with acute STEMI, and the patients were further classified in 2 age groups: patients≥75 years and <75 years. Results Though the older group had a higher prevalence of adverse baseline characteristics and lower final TIMI flow than those of the younger, the procedural success had no difference between two groups. The main adverse clinical events (MACE) for the old group was a little higher comparing with the younger in 12-month following up. Conclusions Our study suggest that drug-eluting stent implantation in elderly patients with acute ST elevation myocardial infarction has high initial procedural success rates despite having more severe baseline risk characteristics, and to shorten the time form symptom onset to PC1 and improve final TIMI flow strategy may decrease MACE among old patients following PCI.
