ABSTRACT
ObjectiveTo explore the relationship between mental health and sleep quality of high-level shooting athletes and its significance to psychological rehabilitation. MethodsIn March, 2021, 21 high-level shooting athletes were investigated using Pittsburgh Sleep Quality Index (PSQI) and Profile of Mood State (POMS). They were divided into normal sleep group (n = 9) and sleep disorder group (n = 12). The psychological state of athletes with different sleep quality was calculated and the correlation was analyzed. ResultsThe scores of tension, anger, fatigue, and total of motional disturb (TMD) in POMS were higher in the sleep disorder group than in the normal sleep group (t > 2.18, P <0.05). The total of PSQI postively correlated with tension, anger, fatigue, depression, panic, and TMD of POMS (r > 0.454, P < 0.05). After step regression, fatigue was the main variable related to PSQI (P = 0.001). ConclusionThe sleep quality of high-level shooting athletes is affected by mental state, and the mental fatigue is the most important factor. The follow-up psychological rehabilitation professionals should pay more attention to the negative emotions and psychological fatigue of shooting event athletes.

The common adverse events in the experimental group were hand-foot syndrome (12.5%), hypertension (12.5%), epistaxis (8.33%) and proteinuria (4.16%), all of which were grade Ⅰ-Ⅱ and controllable without affecting the continuity of chemotherapy. Conclusion The combination of anlotinib, paclitaxel and cisplatin as the first-line treatment of advanced esophageal squamous cell carcinoma can improve the curative effect and the adverse effects are endurable.
ABSTRACT
Objective To compare the clinical outcomes between proximal femoral nail antirotation (PFNA) combined with risedronate sodium and isolated PFNA for the treatment of intertrochanteric fractures in elderly patients.Methods Clinical data of 62 elderly patients with intertrochanteric fracture from January 2011 to April 2013 were prospectively studied.Patients were randomly divided into two treatment groups:risedronate sodium group (the combined PFNA and risedronate) and control group (isolated PFNA).According to AO classification,32 patients in risedronate sodium group (15 males and 17 females,with an average age of 78 years) were divided into type A1 (n=10),type A2 (n=18) and type A3 (n=4).30 patients in control group (13 males and 17 females,with an average age of 77.5 years) were divided into type A1 (n=9),type A2 (n=16) and type A3 (n=5).Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry before and 1 year after operation.The hip joint function was assessed by Harris hip score.Complications and subsequent fragility fractures were evaluated postoperatively.Results 60 patients (30 patients in risedronate sodium group and 30 patients in control group) were followed up for at least one year.All fractures were healed at 6 months after surgery.No significant difference was found between the two groups in BMD in contra-lateral hip before treatment [(-2.58±0.41)kg/m2 vs.(-2.56±0.36)kg/m2,P＞0.05].BMD in contra-lateral hip had significant difference between the risedronate sodium and control groups one year after surgery [(-0.66±0.37)kg/m2 vs.(-1.13 ±0.28)kg/m2,P=0.000].There was no significant difference between the two groups in Harris hip score (P=0.238).During the follow-up,no patient in risedronate group suffered from subsequent fragility fracture after surgery,while lumbar compression fracture occurred in 1 case,distal radius fracture occurred in 1 case,the contralateral hip fractures occurred in 2 cases,postoperatively.Conclusions PFNA treatment combined with risedronate sodium can effectively improve BMD and reduce the risk for refracture,and has a good effect on intertrochanteric fracture in elderly patients.
ABSTRACT
BACKGROUND:Adrenomedulin gene transfection can strength the anti-apoptotic ability of bone marrow mesenchymal stem cels under ischemia and hypoxia, but its mechanism is not yet clear. OBJECTIVE:To investigate the effect of adrenomedulin on the expression of apoptosis-related proteins, Bax, Bcl-2 and Caspase-3, in bone marrow mesenchymal stem cels under hypoxia and ischemia. METHODS:Bone marrow mesenchymal stem cels of Sprague-Dawley rats were isolated, cultured and purified, and then cultured in serum-free medium under hypoxic condition for 0, 3, 6, 9, 12 hours. Then, western blot assay was employed to detect the expression of Bax, Bcl-2 and Caspase-3 so as to determine the optimal hypoxia time that was determined at 6 hours of hypoxia. Depending on whether adrenomedulin pretreatment was done, the cels were divided into control group (with no adrenomedulin pretreatment before hypoxia and ischemia) and adrenomedulin groups with different concentrations (1, 10, 100 μg/L). Afterwards, the expression of Bax, Bcl-2 and Caspase-3 was detected by using western blot assay. RESULTS AND CONCLUSION:(1) After cultured in serum-free medium under hypoxia for 0, 3, 6, 9, 12 hours, the expression of Bax, Bcl-2 and Caspase-3 in bone marrow mesenchymal stem cels were increased (P < 0.05);at 6 hours of hypoxia, the Bax/Bcl-2 ratio and Caspase-3 expression reached the minimum value (P < 0.05). (2) At 6 hours of hypoxia, the expression of Bax and Caspase-3 protein as wel as Bax/Bcl-2 ratio became the lowest in the 100 μg/L group compared with the 1 and 10 μg/L groups, but the expression of Bcl-2 protein reached the peak (P < 0.05). These findings indicate that adrenomedulin can reduce the expression of Bax/Bcl-2 ratio and Caspase-3 protein in bone marrow mesenchymal stem cels cultured in serum-free medium under hypoxic conditions, which is in a dose-dependent manner.
ABSTRACT
This study aimed to evaluate the expressions and clinical significance of bone Gla-protein [BGP], bone alkaline phosphatase [B-ALP] and C-terminal telopeptide of type I collagen [CTX] in patients with osteoporosis [OP], and to provide evidence for developing individualized treatment plans. Seventy-two OP patients in our hospital were selected as an OP group, and another 72 healthy subjects were used as a control group. Their BGP, B-ALP and CTX levels as well as bone mineral density [BMD] values were measured. The correlations between BGP, B-ALP and CTX levels and BMD values were determined. The BGP level of the OP group [[5.61 +/- 5.52] ng/ml] was significantly higher than that of the control group [P<0.05], but the levels of B-ALP and CTX did not differ significantly [P>0.05]. The BMD values of femoral neck and Ward's triangle in the OP group were negatively correlated with the B-ALP levels [P<0.05]. For women OP patients, the BMD values of femoral neck and Ward's triangle were also negatively correlated with the B-ALP levels [P<0.05]. The BMD of femoral neck in the control group was negatively correlated with the CTX level [P<0.05]. Determining BGP, B-ALP and CTX levels can evaluate the bone metabolism degree, which provides evidence for clinical typing of OP and developing treatment strategies
ABSTRACT
BACKGROUND:Previous studies have demonstrated that hepatocyte growth factor (HGF) gene transfection can improve the effectiveness of bone marrow mesenchymal stem cel transplantation, but the mechanism is stil unclear. OBJECTIVE:To observe the effects of HGF gene transfection on c-MET, Bax, Bcl-2, Caspase-3 of bone marrow mesenchymal stem cel s cultured under hypoxia and serum-free conditions. METHODS:(1) Bone marrow mesenchymal stem cel s were isolated and amplified in vitro by differential adhesion method. The infection efficiency of recombinant adenovirus Ad-HGF in bone marrow mesechymal stem cel s was tested by x-gal staining. (2) Bone marrow mesenchymal stem cel s were cultured under hypoxia and serum-free conditions for 0, 3, 6, 9, 12 hours. RT-PCR and western blot assays were used to evaluate the expression of Bax, Bcl-2, Caspase-3. (3) Bone marrow mesenchymal stem cel s were cultured under hypoxia and serum-free conditions for 6 hours, and RT-PCR and western blot assays were adopted to detect HGF, c-Met, Bax, Bcl-2 and Caspase-3. (4) Cel scratch test was used to detect the effect of HGF transfection on the migration of bone marrow mesenchymal stem cel s cultured under hypoxia and serum-free conditions for 6 hours. RESULTS AND CONCLUSION:(1) Transfection efficiency of bone marrow mesenchymal stem cel s was increased with multiplicity of infection in a dose-dependent manner. When the multiplicity of infection was 150, the transfection efficiency was 96.4%. (2) Expressions of Bax and Bcl-2 were gradual y increased with hypoxia time (P<0.05). The Bax/Bcl-2 ratio and Caspase-3 expression reach the minimum at 6 hours of hypoxia (P<0.05). (3) Compared with the control and Ad-LacZ groups, the expressions of HGF, c-Met, Bcl-2 increased, and the expressions of Bax and Caspase-3 decreased in the Ad-HGF group after 6 hours of culture under hypoxia and serum-free conditions (P<0.05). There was no significant difference between the control and Ad-LacZ groups. (4) The mobility of bone marrow mesenchymal stem cel s was higher in the Ad-HGF group than the control group and Ad-LacZ groups after 6 hours of culture under hypoxia (P<0.05). These findings indicate that transfection of HGF in bone marrow mesenchymal stem cel s can increase the expression of c-Met, Bcl-2 and decrease the expression of Bax, Caspase-3 under hypoxia and serum-free conditions, which also enhance the mobility of bone marrow mesenchymal stem cel s under hypoxia and serum-free conditions.

ABSTRACT
OBJECTIVE: To investigate the in vivo possibility of osteogenesis and angiogenesis of tissue-engineered periosteum in rabbits.METHODS: The marrow mesenchymal stem cells (MSCs) derived from New Zealand rabbits were adhered to small intestinal submucosa (SIS) to fabricate the tissue-engineered periosteum. Totally 12 New Zealand rabbits were received critical bone defect in bilateral radii to prepare models. The tissue-engineered periosteum was randomly implanted in one side of bone defect,and the other side was treated by SIS. At 4 weeks after operation, the angiogenesis of tissue engineered bone was detected by Tetracycline fluorescence microscopy and formaldehyde-ink perfusion method; simultaneously, the new bone formation was firmed by haematoxylin-eosin staining.RESULTS: Animals showed normal daily behaviors and non-infection wounds healing. The gross observation showed that bone defects in the experimental side were bridged with newly formed bone; while the defects of the control side were remained empty.Tetracycline fluorescence microscopy and hisotological examination could confirm the new bone tissue formation in the experimental side. The ink staining in new bone specimens suggested that there were abundant of neovasculization in tissue-engineered bone.CONCLUSION: Tissue-engineered periosteum can form new bone in allogenic rabbits and can be vascularized by some inherent mechanism for new bone tissue survivor.
