Objective To explore the treatment of infection after spinal internal fixation.Methods The clinical data of 6 patients with infection after spinal internal fixation in our hospital were analyzed retrospectively.The bacterial culture and drug susceptibility testing were performed to identify the pathogenic bacteria and sensitive antibiotics.Moxifloxacin and/or vancomycin were used empirically for anti-infective therapies first,and then sensitive antibiotics were used according to the results of bacterial culture and drug susceptibility testing.At the same time,imaging examination was performed to determine the infection site and internal fixation,and surgical treatment was decided based on the patients'condition.After operation,the body temperature,inflammatory indexes and drainage of patients were monitored continuously,and the drainage fluid was taken for bacterial culture regularly to evaluate the therapeutic effect.Results The results of bacterial culture in 5 patients were positive and the pathogenic bacteria was staphylococcus aureus,with the susceptibility to vancomycin by susceptibility testing.Among them,1 patient was treated with vancomycin for about 8 weeks because of his advanced age,more basic diseases and high risk of operation;the other 4 patients were received surgery combined with anti-infective treatment with vancomycin for 2 to 4 weeks.One case with negative bacterial culture received surgery combined with anti-infective treatment with imipenem and moxifloxacin.The wound of all patients healed in grade A,the body temperature and inflammatory indexes returned to normal,the low back pain disappeared,and the nerve root symptoms of lower extremities were significantly improved.Conclusion Once the patients with infection after spinal internal fixation are diagnosed,the pathogenic bacterial should be identified as early as possible and sensitive antibiotics should be used.Meanwhile,the internal fixation is removed or re-implanted depending on whether it is infected.

High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

OBJECTIVE: To explore the carrier rate, genotype and phenotype of α-thalassemia fusion gene in Huadu district of Guangzhou, Guangdong province of China, and provide data reference for the prevention and control of thalassemia. METHODS: A total of 10 769 samples who were screened for thalassemia in Maternal and Child Health Hospital of Huadu District from July 2019 to November 2020 were analyzed retrospectively. Blood cell analysis and hemoglobin (Hb) electrophoresis were performed. Thalassemia genes were analyzed by gap-PCR and PCR-reverse dot blot hybridization (PCR-RDB). RESULTS: A total of 9 cases with α-thalassemia fusion gene were detected in 10 769 samples (0.08%). There were 7 cases with fusion gene heterozygote, 1 case with compound of α-thalassemia fusion gene and Hb G-Honolulu, 1 case with compound of α-thalassemia fusion gene and Hb QS. The MCV results of 4 samples of blood cell analysis were within the reference range, the Hb A2 value of 1 case was decreased, and there were no other abnormalities found. CONCLUSION The α-thalassemia fusion gene is common in Huadu district of Guangzhou, and heterozygotes are more common, and current screening methods easily lead to misdiagnosis.

Based on the development of conditions, the etiology and pathogenesis of jingjin (muscle region of meridian) diseases are summarized as 3 stages, i.e. stagnation due to over-exertion at early stage, manifested by tendon-muscle contracture and tenderness; cold condition due to stagnation, interaction of stasis and cold, resulting in clustered nodules at the middle stage; prolonged illness and missed/delayed treatment, leading to tendon-muscle contracture and impairment of joint function at the late stage. It is proposed that the treatment of jingjin diseases should be combined with the characteristic advantages of fire needling and bloodletting technique, on the base of "eliminating stagnation and bloodletting/fire needling". This combined therapy warming yang to resolve stasis and dispels cold to remove nodules, in which, eliminating the stagnation is conductive to the tissue regeneration, and the staging treatment is delivered in terms of the condition development at different phases.

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

Objective To measure the prevalence of mental health symptoms and identify the associated factors among college students at the beginning of coronavirus disease 2019(COVID-19)outbreak in China. Methods We carried out a multi-center cross-sectional study via snowball sampling and convenience sampling of the college students in different areas of China.The rates of self-reported depression,anxiety,and stress and post-traumatic stress disorder(PTSD)were assessed via the 21-item Depression-Anxiety-Stress Scale(DASS-21)and the 6-item Impact of Event Scale-Revised(IES-6),respectively.Covariates included sociodemographic characteristics,health-related data,and information of the social environment.Data pertaining to mental health service seeking were also collected.Multivariate Logistic regression analyses were performed to identify the risk factors. Results A total of 3641 valid questionnaires were collected from college students.At the beginning of the COVID-19 outbreak,535(14.69%)students had negative emotions,among which 402(11.04%),381(10.49%),and 171(4.90%)students had the symptoms of depression,anxiety,and stress,respectively.Meanwhile,1245(34.19%)college students had PTSD.Among the risk factors identified,male gender was associated with a lower likelihood of reporting depression symptoms(AOR=0.755,P=0.037],and medical students were at higher risk of depression and stress symptoms than liberal arts students(AOR=1.497,P=0.003;AOR=1.494,P=0.045).Family support was associated with lower risks of negative emotions and PTSD in college students(AOR=0.918,P<0.001;AOR=0.913,P<0.001;AOR=0.899,P<0.001;AOR=0.971,P=0.021). Conclusions College students were more sensitive to public health emergencies,and the incidence of negative emotions and PTSD was significantly higher than that before the outbreak of COVID-19.More attention should be paid to female college students who were more likely to develop negative emotions.We should strengthen positive and proper propaganda via mass media and help college students understand the situation and impact of COVID-19.Furthermore,we should enhance family support for college students.The government and relevant agencies need to provide appropriate mental health services to the students under similar circumstances to avoid the deterioration of their mental well-being.

OBJECTIVE: To investigate the clinical characteristics and treatment of pneumocystis carinii pneumonia (PCP) in children with acute lymphoblastic leukemia (ALL), in order to improve the early diagnosis and effective treatment. METHODS: Clinical data of five children with ALL developing PCP in the post-chemotherapy granulocyte deficiency phase were analyzed retrospectively. The clinical manifestations, laboratory tests, imaging findings, treatment methods and effect were summarized. RESULTS: The male-to-female ratio of the five children was 1∶4, and the median age was 5.5 (2.9-8) years old. All patients developed PCP during granulocyte deficiency phase after induction remission chemotherapy. The clinical manifestations were generally non-specific, including high fever, tachypnea, dyspnea, non-severe cough, and rare rales in two lungs (wet rales in two patients). Laboratory tests showed elevated C-reactive protein (CRP), serum procalcitonin (PCT), (1,3)-β-D-glucan (BDG), lactate dehydrogenase (LDH) and inflammatory factors including IL-2R, IL-6 and IL-8. Chest CT showed diffuse bilateral infiltrates with patchy hyperdense shadows. Pneumocystis carinii(PC) was detected in bronchoalveolar lavage fluid (BALF) or induced sputum by high-throughput sequencing in all patients. When PCP was suspected, chemotherapy was discontinued immediately, treatment of trimethoprim-sulfame thoxazole (TMP-SMX) combined with caspofungin against PC was started, and adjunctive methylprednisolone was used. Meanwhile, granulocyte-stimulating factor and gammaglobulin were given as the supportive treatment. All patients were transferred to PICU receiving mechanical ventilation due to respiratory distress during treatment. Four children were cured and one died. CONCLUSION PCP should be highly suspected in ALL children with high fever, dyspnea, increased LDH and BDG, and diffuse patchy hyperdense shadow or solid changes in lung CT. The pathogen detection of respiratory specimens should be improved as soon as possible. TMP/SMZ is the first-line drug against PCP, and the combination of Caspofungin and TMP/SMZ treatment for NH-PCP may have a better efficacy. Patients with moderate and severe NH-PCP may benefit from glucocorticoid.

OBJECTIVE: To determine the effects of Chinese medicine (CM) involving triple rehabilitation therapy on the progression of knee osteoarthritis (KOA). METHODS: A total of 722 patients recruited from 38 community health service centers located in China from March 2013 to March 2017 were randomly divided into treatment and control groups equally, using a cluster randomization design. Health education combined with CM involving triple rehabilitation therapy for KOA (electro-acupuncture, Chinese medicinal herb fumigating-washing, and traditional exercises) was administered in the treatment group while conventional rehabilitation therapy (physical factor therapy, joint movement training, and muscle strength training) was administered in the control group. Patients with a visual analog scale (VAS) scores ≽4 were treated with dispersible meloxicam tablets (7.5 mg, once daily). The Lequesne index scores, VAS scores, range of motion (ROM), lower limb muscle strength, knee joint circumference, quantitative scores of KOA symptoms, and the short-form 36 item health survey questionnaire (SF-36) scores were measured for each patient at 5 checkpoints (before treatment, at the 2nd week and the 4th week during the 4-week treatment period, at 1 month and 3 months after end of treatment), and adverse reactions were observed also. RESULTS: A total of 696 patients completed the entire process, with 351 in the treatment group and 345 in the control group. At all treatment checkpoints, the treatment group demonstrated better outcomes than the control group with regard to the total Lequesne index scores, effective rate and improvement rate of the total Lequesne index scores, VAS scores, lower limb muscle strength, knee circumference, quantitative scores of KOA symptoms, and SF-36 scores as well (P<0.05 or P<0.01). No adverse reactions were encountered in this study. CONCLUSIONS CM involving triple rehabilitation therapy can alleviate KOA-related pain and swelling, improve lower limb muscle strength, promote flexion and activity of the knee and improve the quality of life in patients undergoing KOA. It is suitable for patients with early or mid-stage KOA. (Registration No. ChiCTR-TRC-12002538).

In recent years， the incidence rate of andrological diseases has shown a significant growth trend. Considering the unavailability of a perfect theoretical system for andrology in traditional Chinese medicine （TCM） and the complex pathogenesis despite of the limited types of andrological diseases， it is necessary to improve the clinical efficacy of andrological diseases so as to satisfy the needs of patients. Therefore， the China Association of Chinese Medicine （CACM） organized the andrologists of TCM and western medicine and the outstanding young clinicians to discuss the andrological diseases responding specifically to TCM or integrated TCM and western medicine， such as chronic prostatitis， male infertility， benign prostatic hyperplasia， erectile dysfunction， and premature ejaculation， determine their diagnostic criteria in western medicine， and standardize the specifications for TCM diagnosis and treatment based on syndrome differentiation， thus formulating recognized and integrated diagnosis and treatment protocols. Apart from proposing suggestions on the treatment of such andrological diseases with TCM and western medicine， the experts have also figured out the andrological diseases responding specifically to TCM， the optimal intervention time of TCM and western medicine， and the suitable measures including surgery. The resulting consensus helps to better guide the formulation of accurate， personalized， and optimized treatment plans in clinical practice and improve the diagnosis and treatment effects of andrological diseases by giving full play to the advantages of TCM， which will in turn contribute to further innovation and development of TCM.
