Objective To investigate the status quo of health literacy among military personnel stationing on plateau and analyze its influencing factors.Methods National Health Literacy Monitoring Questionnaire(2015),self-made questionnaire for demographic data based on literature,Connor-Davidson Resilience Scale,Simplified Coping Style Questionnaire,and Positive and Negative Affect Scale were employed to survey 2 516 officers and soldiers stationing on plateau with aid of a WeChat APP Questionnaire Star.Their current status of health literacy and its influencing factors were analyzed.Results The survey results showed that the overall health literacy level was 20.03％among the 2 516 participants.The literacy levels of basic knowledge and concepts,healthy lifestyles and behaviors,and health skills were 31.08％,26.23％,and 26.63％,respectively,and the health literacy levels of scientific health concepts,infectious disease prevention and treatment,chronic disease prevention and treatment,safety and first aid,basic medical care,and health information were 40.58％,19.36％,9.62％,82.75％,29.61％,and 45.03％,respectively.Multivariate unconditional logistic regression analysis indicated that the influencing factors of health literacy level were years of working(OR=1.857,95％CI:1.391～2.479;OR=4.657,95％CI:3.297～6.578),ethnicity(OR=0.394,95％CI:0.251～0.620),marriage(OR=0.609,95％CI:0.430～0.861),only-child family(OR=0.759,95％CI:0.585～0.985),home location(OR=0.545,95％CI:0.359～0.827),smoking(OR=1.579,95％CI:1.254～1.988),education level(OR=3.638,95％CI:1.500～8.822),weekly online game time(OR=0.517,95％CI:0.365～0.731;OR=0.351,95％CI:0.172～0.716),number of physical checkups per year(OR=3.251,95％CI:1.359～7.778;OR=4.545,95％CI:1.841～11.221),father's occupation(OR=5.185,95％CI:1.800～14.933;OR=3.229,95％CI:1.261～8.270),mother's occupation(OR=0.221,95％CI:0.086～0.568;OR=0.218,95％CI:0.081～0.587;OR=0.046,95％CI:0.018～0.118),positive coping(OR=1.052,95％CI:1.033～1.072),and negative coping(OR=0.950,95％CI:0.929～0.972).Conclusion The overall health literacy level is quite low among the plateau military personnel in this ministry,and the relevant departments should actively explore effective interventions to comprehensively improve their health literacy based on the influencing factors.

Objective To observe the effect of Zhongtong'an Capsules combined with rivaroxaban tablets on deep venous thrombosis (DVT) of lower extremities after total knee arthroplasty. Methods A total of 82 patients were randomly divided into control group and experimental group, with 41 cases in each group. The control group was treated with rivaroxaban tablets after surgery, while the experimental group was treated with oral administration of Zhongtong'an Capsules on the basis of the control group. The main outcome indicators (occurrence of DVT of lower extremities), secondary outcome indicators[circumference of lower extremities, blood flow velocity of femoral deep vein, whole blood high shear viscosity, whole blood low shear viscosity, hematocrit, plasma viscosity index, serum prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), and plasma D-dimer (D-D)], and therapeutic effects[the Visual Analogue Scale (VAS) score for pain, score of American Hospital for Special Surgery (HSS) forknee function]were compared between the two groups. Results After 14 days of treatment, the incidence of DVT of lower extremities in the experimental group was 9.76% (4/41), which was significantly lower than 31.71%(13/41) in the control group (χ²=6.011, P < 0.05). Compared with the control group, the experimental group had faster venous blood flow velocity and reduced circumference of lower extremities after 7 and 14 days of treatment (P < 0.05). After 7 and 14 days of treatment, all the hemorheological-related indicators in the experimental group were significantly lower than those in the control group (P < 0.05). After 7 and 14 days of treatment, the PT and APTT in the experimental group were significantly longer than those in the control group, while the FIB and D-D levels were significantly lower than those in the control group (P < 0.05). After 7 and 14 days of treatment, the VAS scores decreased and the HSS scores increased significantly in both groups, and the VAS scores in the experimental group were significantly lower than those in the control group, while the HSS scores were significantly higher than those in the control group (P < 0.05). Conclusion Zhongtong'an Capsules combined with rivaroxaban tablets can effectively improve the hypercoagulable state of patients after knee arthroplasty and reduce the formation of postoperative DVT.

Tumor-induced osteomalacia(TIO)is a rare paraneoplastic syndrome in which tumor-induced osteochondrosis is a metabolic bone disease caused by increased renal excretion of phosphorus due to excessive secretion of fibroblast growth factor 23(FGF23)by tumor tissue.We report here a rare case of TIO in which the tumor was found in the hyoid body and the patient had tertiary hyperparathyroidism.The patient's symptoms did not improve after removal of the tumor from the hyoid body,and the patient's hypophosphatemia was gradually improved after subsequent removal of the left parathyroid gland.TIO derived from the tongue tumor is very rare,and also subsequent tertiary hyperparathyroidism is even rarer.This report helps to improve the understanding of TIO and provides reference in the diagnosis and treatment of TIO.

Objective:To explore the risk factors for death within 1 year after hip fracture surgery in the elderly.Methods:A case control study was made on the clinical data of 551 elderly patients with hip fracture treated in Second Affiliated Hospital of Soochow University from January 2019 to December 2020, including 182 males and 369 females; aged 65-100 years [80(73,86)years]. Joint replacement, cannulated screw fixation or proximal femoral nail fixation were performed. The patients were divided into survival group ( n=494) and death group ( n=57) based on the death within 1 year after surgery recorded at postoperative telephone follow-up. The gender, age, hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, neurological diseases, chronic renal failure, anemia on admission, fracture types, American anesthesiologist Association (ASA) classification, operative methods, preoperative waiting time, duration of operation and perioperative blood transfusion were recorded in two groups. Univariate Cox regression was used to analyze the correlation between the above indexes and death within 1 year after surgery. All indexes with P<0.2 in the univariate analysis were included in multivariate Cox regression analysis to clarify the independent risk factors for death within 1 year after surgery. Results:Univariate Cox regression analysis showed that death within 1 year after surgery correlated with gender, age chronic respiratory diseases, chronic renal failure and anemia on admission (all P<0.01), but not with hypertension, diabetes, cardiovascular diseases, neurological diseases, fracture types, ASA classification, operative methods, preoperative waiting time, duration of operation or perioperative blood transfusion (all P>0.05). Multivariate Cox regression analysis showed that male ( HR=2.08, 95% CI 1.20, 3.61, P<0.01), age ≥ 80 years ( HR=2.22, 95% CI 1.15, 4.28, P<0.05), chronic respiratory diseases ( HR=2.54, 95% CI 1.19, 5.40, P<0.05), chronic renal failure ( HR=4.57, 95% CI 1.27, 16.44, P<0.05), anemia on admission ( HR=2.82, 95% CI 1.38, 5.76, P<0.01) were significantly associated with death within 1 year after surgery. Conclusion:Male age≥ 80 years, chronic respiratory disease, chronic renal failure and anemia on admission are independent risk factors for death within 1 year after hip fracture surgery in the elderly.

The surgical installation accuracy of the components in unicompartmental knee arthroplasty (UKA) is an important factor affecting the joint function and the implant life. Taking the ratio of the medial-lateral position of the femoral component relative to the tibial insert (a/A) as a parameter, and considering nine installation conditions of the femoral component, this study established the musculoskeletal multibody dynamics models of UKA to simulate the patients' walking gait, and investigated the influences of the medial-lateral installation positions of the femoral component in UKA on the contact force, joint motion and ligament force of the knee joint. The results showed that, with the increase of a/A ratio, the medial contact force of the UKA implant was decreased and the lateral contact force of the cartilage was increased; the varus rotation, external rotation and posterior translation of the knee joint were increased; and the anterior cruciate ligament force, posterior cruciate ligament force and medial collateral ligament force were decreased. The medial-lateral installation positions of the femoral component in UKA had little effect on knee flexion-extension movement and lateral collateral ligament force. When the a/A ratio was less than or equalled to 0.375, the femoral component collided with the tibia. In order to prevent the overload on the medial implant and lateral cartilage, the excessive ligament force, and the collision between the femoral component and the tibia, it is suggested that the a/A ratio should be controlled within the range of 0.427-0.688 when the femoral component is installed in UKA. This study provides a reference for the accurate installation of the femoral component in UKA.

Pseudohypoparayhyroidism (PHP) is a rare autosomal dominant or recessive genetic disorder characterized by low calcium, high phosphorus, and target organ resistance to parathyroid. The clinical characteristics and genetic features in 4 patients with Type Ib PHP in the Third Xiangya Hospital, Central South University, have been reviewed. All 4 patients had low calcium, high phosphorus, and parathyroid resistance. Among them, 2 patients had slightly elevated thyroid stimulating hormone and mild features of Albright's hereditary osteodystrophy, and one patient had hypokalemia. No guanine nucleotide-binding protein alpha-stimulating activity polypeptide 1 (GNAS) and gene variant associated with hypokalemia were identified using the whole exome sequencing. The results of the methylation-specific multiple ligation-dependent probe amplification showed that there were abnormal methylation of the upstream differentially methylated regions of GNAS in the 4 patients. There were phenotype overlap among the various subtypes of PHP. Detection of GNAS gene methylation in patients with clinical suspicion of Type Ib PHP is helpful for the diagnosis and treatment of PHP.

Objectives:To investigate the nursing effect of perioperative enhanced recovery after surgery（ERAS）management model in elderly patients with hip fracture.Methods:A retrospective case-control study was conducted to analyze the clinical data of 94 elderly patients with hip fracture admitted to Second Affiliated Hospital of Soochow University from July 2017 to June 2018，including 24 males and 70 females aged 76-98 years［（83.7±5.4）years］. There were 54 patients with intertrochanteric fracture and 40 patients with femoral neck fracture. Surgical method was proximal femoral nail antirotation（PFNA）fixation or artificial hip arthroplasty. A total of 44 patients were managed by ERAS（enhanced recovery group）and 50 patients by traditional nursing（traditional rehabilitation group）. The off-bed time was compared between the two groups from aspects of different fracture sites，bone mineral density and causes of injury. The visual analogue scale（VAS）was tested preoperatively and at postoperative days 1，3 and 7. The complications were recorded at postoperative 1 month. The activity of daily living（ADL）score was assessed preoperatively and at postoperative 1 week，1 month and 3 months. The Harris hip score was assessed at postoperative 1 week，1 month，3 months and at the last follow-up. The length of hospital stay and death at postoperative 3 months and at the last follow-up were recorded.Results:All patients were followed up for 12-24 months［（17.7±6.2）months］. In enhanced recovery group，the off-bed time of patients with different fracture sites（femoral neck，femoral intertrochanter），bone mineral density（>-2.5 SD，≤-2.5 SD）and causes of injury（falls，traffic accidents and others）were markedly shortened as compared with traditional rehabilitation group（ P<0.01）. There was no significant difference in VAS between the two groups before operation（ P>0.05）. However，the VAS in enhanced recovery group was（3.4±0.9）points，（2.7±0.5）points，（1.7±0.6）points at postoperative days 1，3 and 7，significantly lower than that in traditional rehabilitation group［（4.3±1.1）points，（3.5±0.5）points，（2.7±0.9）points］（ P<0.01）. One month after operation，the incidence of pulmonary infection was 0% in enhanced recovery group and 28%（14/50）in traditional rehabilitation group（ P<0.01）. While there showed no significant differences in incidences of cardiovascular system，nervous system，urinary tract infection，lower limb deep vein thrombosis，impaired liver and kidney function，anemia，electrolyte disorder or hypoalbuminemia between the two groups（ P>0.05）. There was no significant difference in preoperative ADL score between the two groups（ P>0.05）. The ADL score in enhanced recovery group was（37.0±6.6）points，（70.1±8.4）points，（86.2±9.3）points at postoperative 1 week，1 month and 3 months，significantly higher than that in traditional rehabilitation group［（26.5±10.4）points，（50.1±11.4）points，（70.7±9.0）points］（ P<0.01）. The Harris hip score in enhanced recovery group was（80.9±8.6）points at postoperative 1 month，significantly higher than that in traditional rehabilitation group［（71.1±9.2）points］（ P<0.01）. There were no significant differences in Harris hip score between the two groups at postoperative 1 week，3 months and at the last follow-up（ P>0.05）. The length of hospital stay was（4.7±2.4）days in enhanced recovery group，significantly shorter than（7.8±3.9）days in traditional rehabilitation group（ P<0.01）. The enhanced recovery group showed no death within 3 months after operation and 2 deaths［5%（2/44）］at the last follow-up，while the traditional rehabilitation group revealed 4 deaths［8%（4/50）］within 3 months after operation. There was no significant difference in the mortality between the two groups until the last follow-up（ P>0.05）. Conclusion:For elderly patients with hip fracture，perioperative ERAS management model can effectively shorten periods in bed，relieve postoperative pain，reduce incidence of postoperative pulmonary infection，accelerate recovery of hip function，improve quality of life，shorten length of hospitalization and promote early recovery.

Objective:Kallmann syndrome(KS) is a complex genetic disease characterized by congenital hypogonadotropic hypogonadism and anosmia. More than 20 genes have been reported to be associated with KS. Herein, we explore potential genetic aberration in 3 KS patients using the whole-exome sequencing. The potentially pathogenic variants filtered were validated by Sanger sequencing.Methods:Genomic DNA was extracted from the peripheral blood of 3 patients with KS and their family members. Sanger sequencing and pedigree verification were performed on the pathogenic variants identified using whole-exome sequencing. The function of the mutation sites were analyzed with bioinformatics software.Results:The proband 1 was a 25 years old male, characterized by lower gonadotropin gonad hypofunction, early grey hair and bilateral sensorineural hearing loss. A heterozygous mutation c. 475C>T(p.R159W) of SOX10 gene was detected in the proband 1. His mother, sister and cousin who had KS phenotype were also found carrying this mutation, showing an autosomal dominant inheritance. The proband 2 was a 15-year-old male with hypogonadotropic hypogonadism and unilateral renal agenesis. The proband was hemizygous for c. 844delC(p.R282Vfs*28) of ANOS1 gene, his mother was heterozygous for the mutation, which was consistent with the X-linked recessive inheritance. The proband 3 was a 21 years old female, characterized by hypogonadotropic hypogonadism and anosmia. A heterozygous missense mutation c. 149G>A(p.R50Q) was detected in FGF17 gene. The mutation p. R50Q was predicted to be pathogenic by the SIFT and PolyPhen2 programs, and has not been reported in HGDM database yet, which considered to be a novel mutation.Conclusion:KS is a clinically and genetically heterogeneous disease. In this study, ANOS1 c. 844delC, SOX10 c. 475C>T and FGF17 c. 149G>A mutations were found in 3 patients with KS by whole exome sequencing, which would expand the genotypic and phenotype spectrum of KS.

Objective:To investigate the effect of early ambulation time on lower limbs muscle strength and fear of falling in patients with total knee arthroplasty, so as to provide basis for promoting the postoperative rehabilitation of patients undergoing total knee arthroplasty.Methods:A total of 210 patients after unilateral total knee replacement from July 2018 to December 2019 in the Second Affiliated Hospital of Soochow University were included and assigned to experimental group 1, experimental group 2 and experimental group 3 by random digits table method, each group contained 70 cases, and the patients began ambulation at 16, 20, 24 hours after knee replacement, respectively. The peak torque (PT) of knee joints flexors and extensor as well as hamstrings quadriceps ratio (H/Q) were compared among three groups at 1 week, 1 month and 3 months after knee replacement. The fall efficiency was evaluted by Modified Fall Efficacy Scale (MFES), the fear of falling rate was conducted by single item method.Results:After 1 month of knee replacement, the PT of knee joints flexor and extensor and H/Q were (18.73±5.49) N·m, (37.56±7.76) N·m, (48.08±9.19)% and (18.44±5.27) N·m, (37.04±7.07) N·m, (47.49±9.30)% in the experimental group 1 and experimental group 2, which were higher than those in the experimental group 3(16.38±2.85) N·m, (33.75±6.75) N·m, (43.48±7.17)%, the differences were statically significant ( t values were 2.316-3.057, P<0.05). After 1 week of knee replacement, the fear of falling rate were 72.3%(47/65) and MFES scores were (3.14±0.58) points in the experimental group 1, 53.7%(36/67), (3.81±0.65) points and 50.8%(32/63), (3.87±0.74) points in the experimental group 2 and experimental group 3, the fear of falling rate significantly increased and MFES scores significantly decreased in the experimental group 1 compared to the experimental group 2 and experimental group 3, the differences were statistically significant ( χ2 values were 5.780, 4.878, t values were 6.221, 6.129, P<0.05). Conclusions:Twenty hours after knee replacement is the best time for ambulation, which can shortern the time for lower limbs muscle strength recovery and reduce the risk of fear of falling.

Eight triterpenes were isolated from the methanol extract of Galbanum by various chromatographic methods including silica gel, ODS opening column, recrystallization and semi-preparative HPLC. Their structures were determined by spectroscopic methods and physicochemical properties as 3β,19α,21α-trihydroxyl-12-en-28-oic acid (1), sumaresinolic acid (2), 3β,19α-dihydroxyl-12-en-28-oic acid (3), oleanolic acid (4), 3β,6β,19α-trihydroxyl-12-en-28-oic acid (5), 19α-hydroxy oleanonic acid (6), 6α-hydroxy oleanonic acid (7), and (11R,12R)-3α,6α-dihydroxy-epoxyolean-28α,13α-olide (8). Among them, compound 1 is a new compound, while compounds 2-8 were newly isolated from the Apiaceae family. The ability of compounds 1-8 to inhibit cholinesterase was determined with an improved Ellman method. Compound 1 showed strong inhibitory activity against butyrylcholinesterase. The molecular docking results indicated that Trp82, His438, Phe329 and Ala328 played an important role in the binding of compound 1 to butyrylcholinesterase.
