ABSTRACT
Objective:To investigate the clinical efficacy of three-connections and four-screwings technique in the treatment of high double column acetabular fractures through a single ilioinguinal approach.Methods:A retrospective study was conducted to analyze the data of 42 patients who had been treated for high double column acetabular fractures from June 2017 to June 2020 at Trauma Ward 2, Department of Orthopedics and Traumatology, The First Hospital of Traditional Chinese Medicine of Changde. There were 19 males and 23 females with an age of (42.7±25.6) years. 29 injuries were due to a traffic accident, 12 ones to fall from a height, and one to fall. The time from injury to operation was (4.5±2.1) days. All the patients were treated by the three-connections and four-screwings technique through a single ilioinguinal approach. Briefly, the anterior column was connected and secured to the main bone using 3 routes, and the posterior column was attached and fixated to the anterior column reset using 2 or 3 of the 4 screwings. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, hip function at the last follow-up and complications during the follow-up were recorded.Results:For this cohort, the operation time was (150.0±30.5) min, and intraoperative blood loss (300.0±50.0) mL. According to the Matta scale for postoperative acetabular fracture reduction, 34 cases were excellent, 6 cases good, and 2 cases acceptable, with an excellent and good rate of 95.2% (40/42). After operation one patient had fat liquefaction and wound exudation which responded to drainage and dressing change. The 42 patients were followed up for (15.0±3.4) months. All fractures healed after (11.0±2.0) months. By the modified Merle d'Aubigné & Postel scoring system, the hip function was evaluated at the last follow-up as excellent in 33 cases, as good in 6 cases, and as fair in 3 cases, yielding an excellent and good rate of 92.9% (39/42).Conclusions:In the treatment of high double column acetabular fractures, the three-connections and four-screwings technique through a single ilioinguinal approach can lead to fine reduction and rigid fixation by lag screw compression and neutralization plate protection. Consequently, early functional exercises can be performed to secure good therapeutic outcomes for the patients.

ABSTRACT
Building a professional clinical research team inside hospitals is in favor improving their research abilities,accelerating the clinical discipline construction,improving their comprehensive influence.Also it fits the objective of general hospital development under gate-keeping system.Now in domestic,the percentage of professional research staff in large hospitals accounts was much less than the international level.The main reasons included the misunderstanding of constructing the research-oriented hospitals,insufficient human resources enrollment,less attractive environment to the highlevel researchers and the absence of relevant degree training programs.To enhance the construction of research-oriented hospitals,it's of key importance to build the professional research team in hospitals.Besides,the hospital has to update management conception,broaden the channels of talent cultivation,grasp the development of the subject accurately and interact with the basic medicine and public health subject,increase the financial investment and perfect the relevant management regulations.
ABSTRACT
Objective To investigate the relationship between the posttraumatic growth in cancer patients and patients' quality of life. Methods 123 cancer patients were measured with posttraumatic growth inventory (PTGI) and EORTC QLQ-C30. Means and standard deviations were used to describe the domain and the range change of posttraumatic growth. Correlation and multiple linear regression analysis were conducted to explore the relationship between the patients' posttraumatic growth and their quality of life. Results 4 of 5 factors in PTGI showed significant positive change, including connection with others [(28.17±7.97) scores], new possibilities [(16.15±6.06) scores], personal strength [(15.42±4.69) scores], and appreciation of life [(11.51±3.80) scores], meanwhile, the spiritual change [(5.07±2.67) scores] had no significant growth. The sum of PTGI was related positively to the role function of the patients. New possibilities (r=0.193), personal strength (r=0.290) and appreciation of life (r=0.284) were correlated positively with global health status. Multiple regression analysis indicated that personal strength (β=0.373, t=3.66) and appreciation of life (β=0.322, t=2.99) could predict positively to global health status, however, relating to others predicted negatively to global health status (β=-0.396, t=-3.63). Conclusion Posttraumatic growth has been found in cancer patients, including some predicting factors of patients' quality of life, such as personal strength, life appreciation and relating to others.

ABSTRACT
Objective To explore the reliability and validity of the Chinese revised version of the Intolerance of uncertainty scale(IUS).Methods A total of 930 college students completed the IUS.45 college students participated in the retest 3 weeks later.The self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were used as criterions for assessment of the validity of the Chinese revised version of IUS.Results The Chinese revised version of IUS contained 21 items.Exploratory factor analysis found a two-factor model (negative belief and emotional experience,behavioral dysfunction and negative self-reference) with a cumulative variance contribution rate of 42.09%.And the results of Confirmatory factor analysis (x 2/df =2.82,GFI =0.90,TLI =0.90,CFI =0.91,RMSEA =0.065) indicated that this model provided a reasonable good fit for Chinese college students.The Cronbach α of internal consistency reliability were good for IUS and two subscales,which were 0.929,0.885 and 0.864,respectively.The test-retest reliabilities for IUS and two subscales were 0.782,0.766 and 0.714 respectively.The IUS scores were positively correlated with the scores of SAS and SDS (r =0.489 ~0.575,P < 0.001).Conclusion It suggests that the Chinese revised version of IUS has good reliability and validity,which is qualified enough for relevant research and applications for Chinese adults.
ABSTRACT
Aim To investigate the potential role of desipramine(DP) on lipoplysaccharide(LPS)-induced acute lung injury(ALI)and the mechanism of its action.Methods Kunming mice were divided into four groups randomly:NS group(NS),DP control group(DP),LPS group(LPS)and DP treatment group(DP+LPS).The model of ALI in mice was induced by lipoplysaccharidel(LPS,10 mg·kg~(-1),ip).Six hours after LPS challenged,the lung samples were taken for determination of lung wet-to-dry weight ratio(W/D),myeloperoxidase(MPO)activity,and malondialdehyde(MDA)content.The bronchoalveolar lavage fluid(BALF)samples were analyzed for total protein concentrateion and white blood cell(WBC)count.The levels of tumor necrosis factor-α(TNF-α)in lung were measured by ELISA.Results LPS could significantly increase the total protein concentration and WBC number in BALF.The lung W/D ration,MPO activity,MDA content and the levels of TNF-α in lungs all increased after ip injection of LPS.Pretreatment with DP decreased all the changes induced by the LPS.Conclusion Pretreatment with DP protects lung from LPS-induced lung injury in mice,which is,at least in part,through inhibiting the level of TNF-α and decreasing the sequestration of neutrophils and lipid peroxidation.
ABSTRACT
Objective The purpose of this study was to investigate the expression of mitochondrial motility-related gene mirol and mitochondrial energy metabolism during an acute bout of prolonged exercise. Methods CS7 BL/6 mice underwent a moderate intensity treadmill running with the slope of 0° and at the speed of 13m/min, and they were randomly divided into 5 groups:resting group(R),exercise groups running for 30min(E30),60min(E60),90min (E90) and 120min(E120),respectively. Respiratory control index and ATP synthesis activity in isolated mitochondria were detected. Skeletal muscle H_2O_2 concentration,mirol mRNA expressions were also measured. Results (1)mirol mRNA contents were significantly increased in groups E30 to E120,as compared with the group R;and mirol mRNA expression increased 32.8%, 107.6%,63.8% and 44.8% respectively in groups E30 to E120. (2)H_2O_2 contents of skeletal muscle were clearly increased in group s E30 to E120. (3)ATP synthesis activity elevated at 30 min of exercise and returned to the baseline thereafter,whereas respiratory control index without remarkable change in groups E30 to E120. Conclusion Muscular mirol mRNA expression significantly increased during 120min of exercise as compared with the resting status and thus facilitated the mitochondrial respiratory and ATP synthesis for matching the energy demand during exercise.
