BACKGROUND:Pediatric knee dysfunction is a congenital malformation. Fusion and fixation can effectively eliminate pain, but no joint has active function. Total knee arthroplasty is a safe and effective method to relieve pain and to rebuild its function. With the continuous development of total knee arthroplasty, the type of knee prostheses is more. OBJECTIVE: To study the efficacy of different reconstruction methods for children with stunted knee arthroplasty. METHODS:120 knee stunted children were equaly divided into treatment group and control group depended on the reconstruction, and then al children were given the artificial knee replacement surgery and were completed by the same group of physicians. In the control group, stable fixed platform prosthesis was selected. In the treatment group, the non-limiting prosthetic-posterior cruciate ligament resection of low contact pressure rotating platform prosthesis was given. Operative time, blood loss, postoperative hospital stay, and complications were observed in both groups. Al patients were folowed up for 3 months. Knee function was assessed by Hospital for Special Surgery and American knee society knee score. Multivariate regression analysis was used to analyze the possible factors affecting Hospital for Special Surgery score during folow up. RESULTS AND CONCLUSION: No significant difference in operative time, blood loss and postoperative hospital stay was compared in both groups (P> 0.05). The postoperative overal incidences of inflammatory response, wound healing, periprosthetic infection, and joint stiff were significantly lower in the treatment group than in the control group (P < 0.05). At 3-month folowed-up, Hospital for Special Surgery and American knee society knee score clinical score and functional score were significantly higher in the treatment group than in the control group (P < 0.05). Hospital for Special Surgery score > 80 served as a standard. Multivariate regression analysis results showed that age, type of prosthesis, and varus deformity were the major independent risk factors for affecting joint replacement (P< 0.05). Results indicate that knee arthroplasty for knee dysfunction obtained good prognostic effect. Simultaneously, the non-limiting application of prosthetic reconstruction can effectively reduce postoperative complications and improve knee function.

Objective To determine the independent risk factors for sepsis in patients with large area burns.Methods The study enrolled 307 patients with large area burns treated from June 2014 to June 2015.Related variables included age,gender,visit time,emergency eschar open,burn index,tangential excision of eschar during shock stage,delayed resuscitation during shock stage,oxygen pressure(PaO2),carbon dioxide pressure (PaCO2),assisted ventilation mode,mechanical ventilation time,inhalation injury,prophylactic tracheotomy,continuous lactic acid rise,refractory hypernatremia,heart-lung disease history,and diabetes history.Correlation of the variables with the incidence of sepsis was observed.Independent predictors of sepsis in patients with large burns were differentiated using the Logistic regression analysis.Results Delayed resuscitation during shock period (OR =1.747,95％ CI 1.822-7.431,P ＜ 0.05),continuous lactic acid rise (OR =1.758,95％ CI 1.137-4.002,P ＜ 0.05),refractory hypernatremia (OR =2.985,95％ CI 1.074-6.782,P ＜ 0.05),moderate and severe inhalation injury(OR =14.764,95％ CI 0.892-47.323,P ＜ 0.05) and burn index (OR =5.017,95％ CI 1.075-23.572,P ＜ 0.05) were found be independently associated with sepsis in patients with large burns.Conclusions These independent risk factors for sepsis in large area burn patients deserve more attention.Early and timely treatment measures may reduce the incidence of sepsis.

In the past two years, researchers have been exploring the precision medicine. Thanks to the development of sequence industry and clinical study, the big data about the precision medicine have been more and more sufficient. However, how to deal with the precision data is still a question for clinicians. We focus on the hot issues that disturb clinicians most, wanting to help them to make suitable decisions between the traditional and precision medicine of breast cancer. We believe the precision medicine is on the way.

OBJECTIVETo find out the distribution of noniodized salt and related affecting factors in Xinjiang.

METHODUsing NTTST's iodized salt inspection Plan.

RESULTSA total number of 17 973 house holds being surveyed in which 69.4% of those used iodized salt and 30.5% used noniodizd salt. In northern Xinjiang, 7 672 households being surveyed in which 83.9% used iodized salt while in eastern Xinjiang 1 200 house holds being surveyed in which 62.2% used iodized salt. In southern Xinjiang, 9 101 house holds being surveyed in which 58.2% used iodized salt. Data showed a statistically significant difference (chi(2) = 1 329.87, P < 0.01). The noniodized salt comes from shop-on-wheels (57.4%) and rock salt (23.0%). The source of iodine was different in different areas. In eastern and southern Xinjiang it came from shop-on-wheels, while in northern Xinjiang came from retail sites. Factors related to the use of iodized salt were awareness about iodine deficiency disorders (IDD) and income.

CONCLUSIONPrograms on fighting against iodine deficiency in Xinjiang needs more attention, especially in the following aspects as publicity on IDD, administration of salt market and supervision system.

But at the same time of the craze, there are still some problems in the intelligent decision-making system. Combining the work of the research groups in this field, this paper explores the current confusions and solutions, and hopes to help clinicians better understand intelligent decision-making. It is believed that with the deepening of the concept and the advancement of technology, intelligent decision-making will become a good help for doctors in the future.

Real-world study is increasingly becoming an important source of evidence for changing clinical practice, especially for clinical problems that can′t be randomized. In recent years, real-world research in the field of breast cancer has gradually became a boom. Existing research results have begun to assist in the epidemiological analysis of breast cancer, promote the approval of rare diseases diagnosis and indication, and promote the analysis of real-world treatment status and evaluation of curative effects. Chinese scholars have also established databases and carried out relevant real-world research, providing real-world evidence for clinical practice in China. But domestic research is still in its infancy. The number of real-world research literature published by domestic scholars is relatively small, and there is a lack of pragmatic randomized clinical trial and real-world research for decision-making. In the future, we need to take advantage of the abundant diagnosis and treatment resources, further improve the database, and carry out real-world study on drug development based on population data in China.

OBJECTIVE： To establish HPLC fingerprint of Nüjin pills， and to conduct cluster analysis and principal component analysis. METHODS： HPLC method was adopted. The determination was carried out on Agilent ZORBAX Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.2％ formic acid solution （gradient elution） at the flow rate of 1.0 mL/min. The detection wavelength was set at 270 nm， and column temperature was 30 ℃. The sample size was 10 μL. Using baicalin as reference， HPLC fingerprints of 10 batches of samples were determined. The similarity of 10 batches of samples was evaluated by TCM Chromatographic Fingerprint Similarity Evaluation System （2012 edition） to confirm common peak. Cluster analysis and principal component analysis were performed by using SPSS 22.0 software. RESULTS： There were 21 common peaks in HPLC chromatograms of 10 batches of samples， the similarity of which was all over 0.95， which indicated that in 10 batches of samples， the chemical composition was consistent， but the contents of these components were different. When euclidean distance was equal to 25，10 batches of sample were divided into two categories； S3 was included in the first category， and others were included in the second category. When euclidean distance was equal to 5， the second category could be divided into three sub-categories， one sub-category was S2， S4， S6 and S10； one sub-category was S5， S9； one sub-category was S1， S7， S8. Through the principal component analysis， the cumulative contribution rate of three main component factors was 90.642％， and comprehensive score of S3 was the highest with the best quality. CONCLUSIONS： Established HPLC fingerprint， the results of cluster analysis and principal component analysis can provide reference for quality evaluation of Nüjin pills.

Objective:To investigate the clinical experience of different types of femoral perforator flaps in the reconstruction of oral and maxillofacial head and neck defects.Methods:From January 2018 to January 2021, 573 patients with oral and maxillofacial head and neck defects reconstructed by femoral perforator flap were collected in the Department of Maxillofacial Oncology, the Third Affiliated Hospital of Air Force Military Medical University (age range of 21-76 years, with a male to female ratio of 1.23∶1). According to the type of perforator flap, the patients were divided into ALT group, AMT group, TFL flap group and free muscle flap group. The incidence of postoperative complications, wound healing time and drainage volume in femoral area were compared among the 4 groups.Results:The ALT flap was used in 527 cases: 22 flaps had vascular crisis, 14 flaps had infection, 8 flaps had necrosis, 519 flaps survived; the mean healing time of the wound was (14.50±3.19) days, and the mean drainage volume was (49.9±21.3) ml. 28 cases were repaired with AMT flap: 2 flaps had vascular crisis and 1 had infection. All the flaps survived; the mean healing time of the wound was (14.18±2.75) days, and the mean drainage volume was (50.3±23.0) ml. 11 cases were repaired by TFL flap: 1 flap had vascular crisis and 1 had infection. All the flaps survived. The mean healing time of the wound was (14.09±2.66) days, and the mean drainage volume was (54.1±25.0) ml. 7 cases were repaired by free muscle flap survived without vascular crisis, infection and other postoperative complications; the mean healing time of the wound was 14.14±1.86, and the mean postoperative drainage volume was (49.9±21.1) ml. There was no significant difference in complication rate (flap necrosis, vascular crisis, infection, etc.) and repair effect among 573 patients with different flap types. The postoperative follow-up was conducted for 6-24 months, and the donor area was smooth and good in appearance, without obvious scar or functional influence. The repair effect of the affected area was satisfactory.Conclusions:Although there is a certain proportion of perforator vessel variation in the femoral perforator flap, the flap can be designed freely according to different types of variation. The thigh perforator flap has an essential application value in the repair of oral and maxillofacial head and neck defects.
