Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To investigate the alterations in soft tissue morphology and thickness in the mid-face region of patients with cleft lip and palate (UCLP) secondary to maxillofacial deformity following Le Fort I osteotomy.Methods:A total of 22 patients (16 males and 6 females aged from 17 to 28 years with an average of 20 years) diagnosed with cleft lip and palate secondary to maxillofacial deformity were collected from the Wuhan University Hospital of Stomatology from July 2012 to August 2020. All patients underwent Le Fort I osteotomy. CBCT scans were obtained at T0 (3 days before surgery), T1 (7 days after surgery), and T2 (1 year after surgery). The Dolphin11.95 software and 3D Slicer software were utilized to measure and analyze the soft tissue near the mid-face osteotomy line. Differences in soft tissue thickness before and after surgery were compared.Results:Before and after the operation, the soft tissue thickness at P3, P5, P6, and P8 on the affected side was thicker than that on the healthy side, and the difference was statistically significant, with a P-value of <0.05. At P5, P6, P7, P8, and P9 below the osteotomy line at T2-T0, the degree of postoperative thinning on the affected side was more apparent than that on the healthy side, and there was statistical significance at P6 ( P<0.05). The postoperative soft tissue asymmetry in the Ck region was improved compared with the preoperative one. The preoperative average protruding of the affected side was 0.63 compared with the healthy side, and the postoperative value was 0.17. The preoperative and postoperative Mann-Whitney U tests showed significantly statistical difference. Conclusions:After Le Fort I osteotomy, the facial asymmetry of patients with unilateral cleft lip and palate secondary to maxillofacial deformity is improved. However, there is still a difference in the soft tissue thickness between the healthy side and the affected side, and the change in soft tissue thickness on the affected side is more significant than that on the healthy side.

Primary familial brain calcification (PFBC) is an inherited neurodegenerative disorder mainly characterized by progressive calcium deposition bilaterally in the brain, accompanied by various symptoms, such as dystonia, ataxia, parkinsonism, dementia, depression, headaches, and epilepsy. Currently, the etiology of PFBC is largely unknown, and no specific prevention or treatment is available. During the past 10 years, six causative genes (SLC20A2, PDGFRB, PDGFB, XPR1, MYORG, and JAM2) have been identified in PFBC. In this review, considering mechanistic studies of these genes at the cellular level and in animals, we summarize the pathogenesis and potential preventive and therapeutic strategies for PFBC patients. Our systematic analysis suggests a classification for PFBC genetic etiology based on several characteristics, provides a summary of the known composition of brain calcification, and identifies some potential therapeutic targets for PFBC.

Objective To understand the various HPV types and the factors influencing their distribution among women with normal cervical cytology in the Shanghai area, to provide basic data for cervical cancer prevention and vaccine use.Methods A questionnaire-based survey was conducted among 3 372 married women in the Shanghai area. A PCR reverse dot blot (PCR-RDB) method was adopted for HPV genotyping of cervical exfoliated cell samples from 3 206 women. Odds ratio (OR) for HPV infection were analyzed using logistic regression. Results Of the 3 206 women investigated, 669 (20.87%) were positive for HPV infection. The highest incidence of HPV infections was seen in the age groups of 55-59 years, 50-54 years and 45-49 years, with the rates of positive detection being 27.67%, 21.65%, and 21.55%, respectively. While 70.4% of the positive cases had a single infection, 29.6% showed multiple infections. In cases with multiple infections, double infection was predominant (20.63%). The top five high-risk gene types were HPV52(3.65%),HPV53(2.71%),HPV51(2.03%),HPV58(1.87%),and HPV16 (1.40%). The top three low-risk gene types were HPV81 (2.03%), HPV42 (1.43%), and HPV55 (1.31%). Among the women with HPV infections,there were 483 having medium-high-risk HPV infection.There were significant differences in the age,the age at first sexual activity,sexual activities per week,education,and alcohol consumption between HPV positive and HPV negative patients. Age stratification showed that the infection rates in the 55-59 years old group were significantly higher than that in the other age groups(χ2=15.349, P=0.000). Both single factor and multivariate non-conditional logistic regression analyses showed that higher education and the start of sexual activity at a later age were protective factors for medium-high-risk HPV infection,with regression coefficients of-0.165 and-0.08,respectively (P<0.01) in the multivariate analysis. The risk factors included age between 55- 59 years, menstrual status (menopause), sexual activity (≥3 times per week) and alcohol consumption. High-risk HPV infections also had the same risk factors,and the odds ratios were 1.558,1.275,and 1.678,respectively(P<0.01).However, 55-59 years of age and alcohol consumption are independent risk factors for medium-high risk HPV infection. Conclusions High-risk HPV in women of Shanghai is commonly caused by HPV52, HPV53, HPV51,HPV58,and HPV16.The high-risk group includes women who are 55-59 years old.While drinking is an independent risk factor for medium-high risk HPV infection, a moderate sex life and delayed age at first sex can reduce the risk of high-risk HPV infections.

BACKGROUND:Bone transplantation is the only method for the repair of bone defects. However, traditional bone transplantation has some disadvantages. Bone tissue engineering, as a new treatment strategy, can achieve the desire therapeutic outcomes. OBJECTIVE:To fabricate a new tissue-engineered scaffold for improving bone repair effectively. METHODS:Hydroxyapatites (HA) with different Ca/P (1.50/1.67) ratios were synthesized by chemical precipitation method and microwave radiation method. Composite scaffolds of palygorskite (APC)/HA/polycaprolactone (PCL)/col agen (COL), APC/calcium deficiency HA (CDHA)/PCL/COL, and APC/PCL/COL (control group) were prepared by solution perfusion-solvent evaporation and ion leaching method. The material characterization, active ingredients, hydrophilic property, and mechanical properties were evaluated by scanning electron microscope, infrared spectrometer, surface contact measuring instrument and universal mechanics, respectively. The histocompatibility of the implant with the host was assessed through animal experiments. RESULTS AND CONCLUSION:By precise control of pH range, HA with different Ca/P ratios could be synthesized. The mechanical properties, air permeability, hydrophilic property of the APC/HA/PCL/COL and APC/CDHA/PCL/COL composite materials were significantly increased compared with the APC/PCL/COL composite material (P<0.05), while the porosity, water absorption expansion rate were significantly decreased (P<0.05). Results from our animal experiments showed that no immune inflammatory reaction was observed suggesting that the composite materials hold good histocompatibility. To conclude, the APC/HA (1.50/1.67)/PCL/COL composite materials are promising bone substitutes in bone tissue repair.

OBJECTIVE:To investigate the clinical efficacy and safety of alprostadil in the treatment of heart failure in pa-tients with normal left ventricular ejection fraction (LVEF). METHODS:120 patients diagnosed as heart farlture with normal LVEF were divided into observation group and control group by radom number table method,with 60 cases in each group. Control group was given symptomatic treatment;observation group was additionally treated with Alprostadil dried emulsion for injection 10μg,bid,on the basis of control group. Both groups received treatment for 5 d. The cardiac function indexes,serum inflammatory factors and oxidative stress indexes were observed in 2 groups before and after treatment,and the occurrence of ADR was com-pared between 2 groups. RESULTS:Before treatment,there was no statistical significance in cardiac function indexes,serum in-flammatory factors and oxidative stress indexes between 2 groups (P>0.05). After treatment,above indexes of 2 groups were all improved significantly,and the observation group was significantly better than the control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Alprostadil can improve cardiac function of patients with heart failure of normal LVEF,improve serum inflammatory factors and oxidative stress level with good safety.
