Objective To investigate 13 high-risk types of HPV (HR HPV) infection rates in women with different grades of cervical lesions.Methods A total of 350 women, who were hospitalized in the department of gynecology in Bao′an Maternity & Child health hospital, were enrolled for the study.TCT technology was used to evaluate the cervical epithelium.The group were divided according to the cytology results.Multiplex real time PCR (mRT PCR) was used to detect the viral loads.HR HPV infection rate of different groups were analyzed using χ2 test or Fisher exact test.HR HPV viral loads of patients in different grades of cervical lesion groups were compared using Kruskal-Wallis or Wilcoxon test, and the age distribution of HR HPV positive group and negative group was analyzed by using Wilcoxon test.Results The HR HPV infection rates of NILM, ASCUS, LSIL, HSIL were 3.4% (10/295), 20.0% (7/35), 78.6% (11/14) and 100.0% (6/6), respectively.HR HPV positivity in NILM was lower than ASCUS (χ2=14.43,P<0.01) and LSIL (χ2=107.69,P<0.01), HR HPV positivity in ASCUS was lower than LSIL (χ2=14.76,P<0.01). The median of HR HPV viral loads in NILM, ASCUS, LSIL and HSIL were 4.10 (3.38-6.27), 5.33 (3.63-6.66), 5.77 (4.01-7.01) and 5.58 (4.19-5.85) respectively (copies/ml,lg).Combined ASCUS, LSIL and HSIL groups into cervical lesion group, HR HPV viral load of which was higher than that of NILM (U=43.0, P<0.05).The median Ages of HR HPV positive group and negative group were 36 and 33, respectively.No statistical significance was found between them (U=4 544, P>0.05).Conclusions The present study revealed that HR HPV infection was related to cervical lesion, but there was no correlation between viral load and cervical lesion grade. In additional, no difference in age distribution was found between HR HPV positive group and negative group.

OBJECTIVETo observe the clinical efficacy differences between modified lateral position and prone position in patients treated with electroacupuncture (EA) for lumbar herniated disc (LHD).

METHODSSeventy-six patients with LHD were randomly divided into a lateral position group and a prone position group, 38 cases in each one. The acupoint selection and treatment method were identical in the two groups except the position. Mingmen (GV 4), Yaoyangguan (GV 3), Dachangshu (BL 25), Xiaochangshu (BL 27), Zhibian (BL 54) and Huantiao (GB 30) were selected. EA was given three times a week, ten times were taken as one course and totally 20 times were given. The visual analogue scale (VAS) and Japanese orthopaedic association (JOA) scale were taken as efficacy criteria, which were evaluated before and after treatment as well as one month after treatment.

RESULTSAfter treatment, VAS and JOA were significantly improved in the two groups (lateral position group:JOA 10.60±2.60 vs 18.92±3.87, VAS 8.13±0.99 vs 2.34±0.81; prone position group:JOA 10.94±2.06 vs 17.02±3.96, VAS 8.02±1.05 vs 2.86±0.96, all<0.01); the VAS and JOA in the lateral position group were higher than those in the prone position group (both<0.05). One month after treatment, VAS and JOA were significantly improved in the two groups (all<0.01), which was more significant in the lateral position group (both<0.05).

CONCLUSIONSThe treatment position could influence the efficacy of EA for LHD, and lateral position pre-sents certain advantages to prone position group.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
