Objective:To study the eftect of plateau environment on the body compositions of soldiers.Methods:A total of 120 male soldiers were selected for the study.All of the study subjects received a physical examination between June and November in 2014.Bio-electrical impedance technique was used to measure the subjects' body composition including 33 parameters such as body mass index (BMI) and body fat mass.Results:Compared to that before entering into the plateau,the levels of 31 parameters were significantly lower after entering into plateau,except the distribution of muscles in left lower limb and ECW/TBW in right upper extremity.Conclusion:The body compositions of soldiers may decrease under plateau environment.This phenomenon need to be interfered purposefully to aTange scientific diets and training intensity.

Vascular birthmarks are the most common disease.The morbidity is about 2.5%,most of the lesions occur in oral and maxillofacial regions which accounts for 40%-60% of the total lesions.In 1982,Mulliken and Glowacki proposed a biologic classification of vascular birthmarks on the basis of their clinical manifestations,histopathological features,and natural history.They defined hemangiomas as vascular tumors with a growth phase,marked by endothelial proliferation and hypercellularity,and an involutional phase.They recognized that many entities referred to as hemangiomas are actually structural malformations of the vasculature,derived from capillaries,veins,lymph vessels,or arteries or from a combination of these sources.The classification was confirmed and issued by International Society for the study of vascular anomality(ISSVA) in 1988.Waner and Suen amended the above category in 1995.This paper presents the new classification of vascular birthmarks and the developments in this field in re-cent years,including the pathology,clinical features and the therapy.For example,the classification of venular malformation categorized by Waner in 1989;the classification of lymphous malformation by Waner and Suen in 1995;and the treatments according to above classifications.

Objective:To investigate the effectiveness and safety of transurethral low power green laser enucleation of prostate (VREP) after transrectal prostate puncture.Methods:The clinical data of 96 patients with VERP in the First Affiliated Hospital of Xinxiang Medical College from October 2020 to October 2021 were retrospectively analyzed. They were randomly divided into the control group ( n=41) and the observation group ( n=55). The control group did not undergo prostate biopsy before operation, and the observation group underwent transrectal prostate biopsy within 1 week before operation. The general data, perioperative indexes, maximum urinary flow rate ( Qmax), international prostate symptom score (IPSS), quality of life score (QOL) and complications of the two groups were compared before and 3, 6 and 12 months after surgery. Results:Preoperatively, the PSA was higher in the observation group compared with the control group ( P<0.05), and the differences in other general information were not statistically significant (all P>0.05). Compared with the control group, the observation group had longer operation times and heavier resected specimens, and the differences were statistically significant (all P<0.05), but there were no statistically significant differences between the two groups in the comparison of enucleation efficiency, crushing efficiency, postoperative hemoglobin (HGB) decline value, postoperative hospitalization time, and postoperative ureter removal time (all P>0.05). At 3, 6 and 12 months postoperatively, Qmax, IPSS and QOL were significantly improved in the observation group compared with the control group (all P<0.05). However, there was no statistically significant difference between the two groups in the comparison of the above-mentioned indexes in the same period after surgery (all P>0.05). There was no statistically significant difference in the complication rate comparison between the two groups ( P>0.05). Conclusions:Transurethral low-power green laser prostate enucleation after transrectal prostate puncture is efficacious and has a certain degree of safety.

Objective: To investigate the effect of magnetic-induced cell targeted transplantation (MagIC-TT) on repair of bone defects in mice using therapeutic fluorescent gene labeled cells into bone tissue and its mechanism. Methods: The proliferation, apoptosis and targeted migration ability were compared between magnetized and unmagnetized murine bone marrow stromal cells labeled with green fluorescent protein (GFP-BMSCs) (n=3). GFP-BMSCs were loaded into tissue engineering bone (TEB) by MagIC-TT in the experimental group (n=5) before the TEB was transplanted into the large femur defects in the model of red fluorescent protein (RFP) transgenic mice. In the control group (n=5) TEB was not loaded with GFP-BMSCs while in the blank group (n=3) the large femur defects were only fixated with intramedullary nails. The effects and mechanism of bone repair were explored 3 months after surgery using X-ray, micro-CT, semi-solid decalcification (SSD) and histology, respectively Results: There were no significant differences between magnetized and non-magnetized GFP-BMSCs in proliferation (0.760±0.029 versus 0.733±0.033) or in survival rate (87.9%±1.0% versus 87.4%±2.0%) (P>0.05), but the mobility of magnetized GFP-BMSCs was significantly higher than that of non-magnetized GFP-BMSCs (P<0.05). The X-ray 3 months after surgery showed that the scaffolds in the experimental group were degraded and that the proximal and distal ends of the femoral defects were connected by new bone tissue. No new bone formation was found in the blank group while a small amount of bone formation was observed in the control group. The Micro-CT showed that stable new bone tissue formed in the femur defects after removal of intramedullary nails in the experimental group. The SSD showed that GFP-MSCs were densely distributed in the scaffolds with red fluorescent protein (RFP) recipient cells penetrating them, indicating involvement of both donor and recipient cells in the formation of new bone. Conclusions MagIC-TT can be used to promote introduction of therapeutic cells into bone tissue to achieve a fine effect on repairing bone defects. Dual fluorescence gene marking combined with SSD shows that both donor and recipient cells may take part in the bone repairing.
