BACKGROUND: Osteopenia has been well documented in adolescent idiopathic scoliosis (AIS). Bone marrow stem cells (BMSCs) are a crucial regulator of bone homeostasis. Our previous study revealed a decreased osteogenic ability of BMSCs in AIS-related osteopenia, but the underlying mechanism of this phenomenon remains unclear. METHODS: A total of 22 AIS patients and 18 age-matched controls were recruited for this study. Anthropometry and bone mass were measured in all participants. Bone marrow blood was collected for BMSC isolation and culture. Osteogenic and adipogenic induction were performed to observe the differences in the differentiation of BMSCs between the AIS-related osteopenia group and the control group. Furthermore, a total RNA was extracted from isolated BMSCs to perform RNA sequencing and subsequent analysis. RESULTS: A lower osteogenic capacity and increased adipogenic capacity of BMSCs in AIS-related osteopenia were revealed. Differences in mRNA expression levels between the AIS-related osteopenia group and the control group were identified, including differences in the expression of LRRC17 , DCLK1 , PCDH7 , TSPAN5 , NHSL2 , and CPT1B . Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed several biological processes involved in the regulation of autophagy and mitophagy. The Western blotting results of autophagy markers in BMSCs suggested impaired autophagic activity in BMSCs in the AIS-related osteopenia group. CONCLUSION Our study revealed that BMSCs from AIS-related osteopenia patients have lower autophagic activity, which may be related to the lower osteogenic capacity and higher adipogenic capacity of BMSCs and consequently lead to the lower bone mass in AIS patients.

Mongolians have a long history of using prescriptions, which can be classified into four stages as follows: the germination and experience accumulation stage before the 13 th century, the theoretical formation stage from the 13 th to 16 th century, the rapid development stage from the 17 th to 20 th century, and the leaping development stage from the mid-20 th century to the present. The prescriptions from the ancient classical or representative medical books have always been used by Mongolian physicians for generations, and they are still in use due to the definite curative effects. In 2008, the Notice on Issuing the Supplementary Provisions to the Registration and Management of Traditional Chinese Medicine(TCM) described that China has attached more importance to the excavation and development of classical prescriptions. As stipulated in the Law of the People's Republic of China on Traditional Chinese Medicine, the classical prescriptions should be those available in ancient TCM classics and still in wide use, with exact curative effects, distinct features, and obvious advantages. This paper expounded the historical formation and development of classical prescriptions in Mongo-lian medicine, introduced the five most influential ancient medical books revealing the formation and development of these classic prescriptions, and traced the origin of such classical prescriptions as Wenguanmu Siwei Decoction, Shouzhangshen Bawei Decoction, Jianghuang Siwei Decoction and summarized the origin, development history and characteristics of classical prescriptions in Mongolian medicine, aiming to provide a reference for their further research and development.

Objective:To evaluate the feasibility and clinical efficacy of deformed complex vertebral osteotomy (DCVO) technique on the treatment of angular kyphosis of cured spinal tuberculosis.Methods:A retrospective study was performed on patients with angular kyphosis of cured spinal tuberculosis who underwent the DCVO technique or posterior vertebral column resection (PVCR) technique from Jan, 2007 to Jan, 2019. 33 patients were included, 18 males and 15 females, the average age was 39.5±15.0 years old (ranged 9-78 years old). The vertebral deformity in thoracic vertebrae 14 cases, thoracolumbar vertebrae 16 cases, and lumbar vertebrae 3 cases. 20 cases underwent the DCVO technique, while 13 cases underwent PVCR technique. For DCVO group, the multiple malformed vertebrae were considered a malformed complex, and a larger range and angle wedge osteotomy was performed within the complex using the DCVO technique. PVCR technique would resect the whole deformed vertebrae, and subsequently brought the two separated spinal columns together with instruments and titanium mesh. The intro-operative blood loss, operating time and complications were recorded. The radiological measurements included preoperative and postoperative spinopelvic parameters, which including thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and segmental kyphosis. The recovery of neurological function was evaluated by Frankle classification.Results:All patients were followed up for 7-72 months. Comparing with the cases underwent PVCR technique, the DCVO group has a significantly lower blood loss (1315.00±462.57 ml), operating time (293.00±83.86 min) and complications rate (1.5%). At the time of preoperation, postoperation and last follow-up, the deformity angle of DCVO group was 96.80°±6.32°, 29.10°±6.96°and 29.05°±6.49°, which gained an average 69.9% correction rate. The statistical analysis suggested that deformity angle was enormously corrected. And there was an insignificant difference between DCVO group and PVCR group. Meanwhile, the preoperative, postoperative and follow-up TK of DCVO group was 96.96°±29.13°, 37.15°±4.88° and 37.00°±3.89°respectively, whosecorrection rate was 67.1%; LL was 66.70°±21.21°, 42.25°±5.53° and 41.90°±4.98°, which have a significant difference between pre-operation and post-operation/follow-up ( F=23.997, P<0.001) ; SVA was 75.95±18.63 mm, 16.30±6.88 mm and 16.55±7.30 mm. PI was 47.50°±6.12°, 47.35°±5.54°and 47.90°±5.93°, PT was 37.25°±9.63°, 18.50°±1.99° and 19.00°±1.65°; SS was 10.25°±8.27°, 29.15°±5.91° and 28.85°±5.77°. The sagittal and spinopelvic parameters of two groups improved significantly at postoperation and follow-up. No obviously difference of spinal parameters was found between two groups at preoperation and postoperation. Both groups have cases with dysneuria. And all of these cases achieved different degrees of recovery at follow-up. Conclusion:The use of DCVO technique for the treatment of post-tubercular angular kyphosis is safe and efficiency. DCVO leads a better clinical outcomes and lower complication rate than VCR technique.

Esophageal squamous cell carcinoma is one of the most common cancer in China, and locally advanced stage remains a heterogeneous and complex disease. Its treatments are constantly evolving. To date, radiochemotherapy and surgery are involved in the comprehensive treatment of this disease. However, because of the specifical anatomical location of esophagus, its physiological function will be impaired after surgical resection. If similar survival is obtained in esophageal cancer, an organ preserving strategy without surgery is of great significance for improving the quality of life. As a non-invasive tumor treatment method, neoadjuvant therapy plays an important role in the comprehensive treatment of preserving the esophagus. Recently, there are studies investigating the role of organ preserving strategy in the comprehensive treatment of esophageal cancer with neoadjuvant therapy, and the recognition of these advances will provide reference value for the comprehensive treatment of esophageal cancer.

Environmental problems are the most serious challenges in the 21st century. With the rapid development of modern industry and agriculture, ecological and environmental deterioration have become the most important factors to restrict the sustainable development of social economy. Microbial cells have strong ability for environmental remediation, but their evolution speed is slower than the speed of emerging pollutants. Therefore, the treatment using the synthetic biology is in urgent need. Full understanding of the microbial degradation characteristics (pathways) of refractory organic pollutants with the help of abundant microbial and gene resources in China is important. Using synthetic biology to redesign and transform the existing degrading strain will be used to degrade particular organic pollutants or multiple organic pollutants. For the complex pollutants, such as wastewater, based on the establishment of metabolic or regulation or resistance related gene modules of typical organic pollutants, artificial flora could be designed to solve the complex pollutants. The rational design and construction of engineering bacteria for typical environmental organic pollutants can effectively promote microbial catabolism of emerging contaminants, providing technical support for environmental remediation in China.

Objective To evaluate the clinical efficacy and feasibility of using the expanding pedicle subtraction osteotomy (E-PSO) technique for the treatment of congenital severe thoracic angular kyphotic deformity.Methods We retrospectively reviewed a cohort of 13patients with congenital severe kyphosis admitted to our hospital from January 2010 to June 2015 including 5 males and 8 females,the average age is (34.9±20.5) years old (ranged 15-55 years old).The vertebral deformity in T7～83 cases,T8～93 cases,T9～102 cases,T10～114 cases,T9～111 case.All cases were treated by E-PSO technique.The multi-malformed vertebrae are considered as a complexus.And the osteotomy was performed within the complexus.The superior and inferior endplate of the complexus were reserved.After the osteotomy was completed,alternately pressed tightly closed the upper and lower parts.Results All cases were followed up for 10-42 months,with an average of 32 months.At the time of preoperation,postoperation andthe last follow-up,the deformity angle was 107.0°±3.5°,23.5°± 1.5° and 23.5°±0.2°;TK was 98.1°±7.6°,28.9°±3.0° and 29.5°±0.1 °,LL was 94.1 °± 1.5°,43.7°± 1.3° and 44.1 °±5.3°;SVA was (-0.6±39) mm,(1.6±7.9) mm and (6±0.7) mm,respectively;PI was 28.9°±1.6°,31.7±12.3°and 31.9°±2.1°;PT was 17.7°±1.9°,13.4°±3.4°and 13.1°±4.2°,SS was 11.3°±0.4°,18.2°±1.1° and 18.7°±2.1°,respectively.The sagittal parameters and spinopelvic parameters except SVA were significantly improved in the post-operation and the last follow-up compared with the pre-operation according to the image data.No significant loss of correction occurred during the follow-up,and there was no statistical difference.The preoperative VAS score was (5.7± 1.4) points,ODI score was (19.8±12.7) points.The last follow-up VAS score was (1.9±0.7) points,the ODI score was (9.2±0.7) points.No case of nerve damage,infection and other complications,and no dissection,displacement and rupture of internal fixation were found during the follow-up.Conclusion The use of E-PSO technique for the treatment of congenital severe thoracic kyphotic kyphosis is feasible and can achieve better curative effect.

Objective To analyze the correlative factors of anemia in patients with non-small-cell lung cancer (NSCLC), and to explore the impact of anemia on prognosis.Methods The clinical data of 473 patients with NSCLC treated at the first time from January 2008 to November 2012 in the Fourth Hospital of Hebei Medical University were analyzed retrospectively.Results There were 273 patients (57.72 ％) with anemia.Anemia occurred in different age (x2 =3.459, P =3.459), different albumin level (x2 =70.648, P =70.648), different PS score (x2 =10.222, P =10.222), whether recent surgery (x2 =4.956, P =4.956), whether recent chemotherapy (x2 =3.627, P =0.037), and other factors.By multiple factors analysis, hypoalbuminemia was an independent risk factor for anemia (P ＜ 0.05).The median OS of the anemia patients was shorter than that of the patients without anemia (15 months vs 17 months, P ＜ 0.05).Conclusions Hypoalbuminemia is the independent risk factor for emergence of anemia.Anemia is the prognosis indicator of shorten survival period, which is an independent factor of prognosis in the NSCLC.

A survey was conducted on a sample of 67 general practitioners ( GPs ) receiving in-service training in Beijing in 2012.Hypertension knowledge mastering and training status were investigated through a self-administered questionnaire .Results showed that the accuracy rates of the 4 domainitems (basic knowledge and skill, lifestyle modification, drug therapy, health management ) were 42.3%(340/804), 48.0%(225/469), 27.8%(96/335) and 70.6%(473/670), respectively with an overall accuracy rate of 49.8%(1 134/2 278).Trainees from urban scored higher than those from rural areas (P<0.01).About one third of trainees indicated that the 3 main teaching sessions they took part in did not cover the content of hypertension management .The hypertension guideline ( primary care version 2009) was most frequently used for training GPs , but only 33.9%(21/62) accessed such training .The results indicate that hypertension knowledge level seems to be generally low among GPs on in-service training in Beijing and the current training situation need to be further improved , particularly for those from rural areas .

Background and objective hTe activation of coagulation and ifbrinolysis is frequently encountered among cancer patients. Such tumors are associated with high risk of invasion, metastases, and negative ifnal outcomes. Non-small cell lung cancer (NSCLC) accounts for approximately 80%to 85%of all lung malignancies. hTis study aims to investigate the prognostic value of blood coagulation tests for NSCLC and provide a reference to patients on the prevention and treatment of thrombophilia. Methods Data were collected from 604 cases of hospitalized patients with histologically conifrmed NSCLC from January 2009 to December 2012 at the Fourth Hospital of Hebei Medical University. Data included the related indexes of coagulation function in patients before treatment [(i.e., prothrombin time (PT), prothrombin time activity (PTA), interna-tional normalized ratio (INR), activated partial thromboplastin time (APTT), ifbrinogen (Fib), D-dimer, and platelet count)], as well as sex, age, pathological type, TNM stage, and lymph node status. Fitfy control subjects without cancer were included in the analysis. Statistical analysis was conducted by using SPSS 13.0 sotfware. Results hTe plasma level of all coagulation tests including D-dimer, Fib, PT, APTT, INR, and platelet counts revealed statistically signiifcant differences between the patient and control group (P<0.001 for all variables;P=0.001,5 and P=0.004,5 for Fib and platelet counts, respectively). hTe squamous subtype exhibited high plasma Fib levels (P<0.001) compared with adenocarcinoma cell lung cancer patients. Fib and PLT levels increased (P<0.001 and P=0.014, respectively), and aPTT decreased (P<0.001) in patients at stages III and IV compared with those in patients at stages I and II. aPTT decreased signiifcantly (P<0.001), and Fib and D-dimer levels increased (P<0.001 and P=0.048, respectively) in N1-3 patients with NSCLC compared with those of N0 patients. Prolonged PT and INR, high plasma Fib levels, and low PTA levels had statistically signiifcant adverse effects on survival (P=0.032, P=0.001, P<0.001, and P=0.005, respectively). Multivariate analyses revealed that only increased INR was associated with a decreased survival rate in the related indexes of coagulation function (P=0.017). Conclusion Patients who have lung adenocarcinoma and/or lymph node metastasis at advanced stages of NSCLC are prone to thrombophilia. Prolonged PT and INR was associated with poor prognosis, and elevated INR was independently associated with a decreased survival rate. PT and INR are promising prognos-tic markers of NSCLC.
