RESUMO
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.

Objective:To evaluate the diagnostic efficiency of hypersensitivity quantitative fecal immunochemical test (hs-qFIT) in colorectal cancer (CRC) and advanced adenoma.Methods:From July to December 2020, consecutive patients aged 50 to 75 years who underwent colonoscopy in Qilu Hospital of Shandong University, and had the Asia-Pacific colorectal screening score of medium or high risk were enrolled. All patients were requested to complete two hs-qFIT before colonoscopy. The diagnostic efficacy of hs-qFIT for CRC and advanced adenoma were assessed. Receiver operating characteristic curve of hs-qFIT in CRC diagnosis was drawn and the area under the curve (AUC) was calculated.Results:A total of 811 patients including 20 (2.5%) cases of CRC, 47 (5.8%) cases of advanced adenoma, 206 (25.4%) cases of non-advanced adenoma, 219 (27.0%) cases of non-adenomatous polyp, 76 (9.4%) cases of other colorectal lesions and 243 (30.0%) cases of non-colorectal lesions were involved. When the fecal hemoglobin cut-off values were 10, 30, 50, 75 and 100 ng/mL, the positive rates of hs-qFIT detection were 17.9% (145/811), 10.9% (88/811), 8.3% (67/811), 7.4% (60/811) and 5.8% (47/811), respectively. When the cut-off value of fecal hemoglobin decreased from 100 ng/mL to 10 ng/mL, the sensitivity of hs-qFIT for CRC diagnosis increased from 90.0% to 100.0%, and the specificity decreased from 96.3% to 84.2%; and the sensitivity of hs-qFIT for the diagnosis of advanced adenoma increased from 19.1% to 66.0%, and the specificity decreased from 95.0% to 85.1%. The AUC of hs-qFIT for the diagnosis of CRC and advanced adenoma were 0.981 (95% confidence interval ( CI) 0.970 to 0.992) and 0.846 (95% CI 0.807 to 0.886), respectively. When the optimal cut-off values were taken, the sensitivity and specificity were 100.0% and 91.2% for the diagnosis of CRC, and 66.0% and 85.3% for the diagnosis of advanced adenoma, respectively. Conclusion:Hs-qFIT can help the early screening of CRC and advanced adenoma.
RESUMO
COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across the globe, posing an enormous threat to public health and safety. Traditional Chinese medicine (TCM), in combination with Western medicine (WM), has made important and lasting contributions in the battle against COVID-19. In this review, updated clinical effects and potential mechanisms of TCM, presented in newly recognized three distinct phases of the disease, are summarized and discussed. By integrating the available clinical and preclinical evidence, the efficacies and underlying mechanisms of TCM on COVID-19, including the highly recommended three Chinese patent medicines and three Chinese medicine formulas, are described in a panorama. We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19, but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.
RESUMO
OBJECTIVE@#To study the reference ranges of platelet and related parameters within 24 hours after birth in preterm infants with different gestational ages.@*METHODS@#According to the inclusion and exclusion criteria, a retrospective analysis was performed for the chart review data of 1 070 preterm infants with a gestational age of 23-36 weeks who were admitted to the neonatal intensive care unit from January to December in 2018. The reference ranges of platelet parameters were calculated for the preterm infants within 24 hours after birth.@*RESULTS@#There were no significant differences in platelet count (PLT) and plateletcrit (PCT) among the preterm infants with different gestational ages (P>0.05). The late preterm infants (34-36 weeks; n=667) had significantly lower mean platelet volume (MPV) and platelet distribution width (PDW) than the extremely preterm infants (23-27 weeks; n=36) and the early preterm infants (28-33 weeks; n=367) (P0.05). The reference ranges of platelet parameters in preterm infants were calculated based on gestational age. The reference ranges of PLT and PCT were (92-376)×10/L and 0.1%-0.394% respectively, for the preterm infants with a gestational age of 23-36 weeks. The reference ranges of MPV and PDW were 9.208-12.172 fl and 8.390%-16.407% respectively, for the preterm infants with a gestational age of 23-36 weeks; the reference ranges of MPV and PDW were 9.19-11.95 fl and 9.046%-15.116% respectively, for the preterm infants with a gestational age of 34-36 weeks.@*CONCLUSIONS@#The MPV and PDW of preterm infants with different gestational age are different within 24 hours after birth, and it is more helpful for clinical practice to formulate the reference range of MPV and PDW according to gestational age.

Objective To provide anatomic evidence for chock-block technique used for acromioplasty.Methods Thirty cadaveric specimens of intact shoulder fixed by formaldehyde solution were used for this anatomic study.They were chosen from 15 males and 15 females and from 17 left and 13 right sides.First the specimens were dissected for observation of general morphology of the acromion.According to the Bigliani's classification,the acromions were sorted in morphology as type Ⅰ (flat),type Ⅱ (curved) and type Ⅲ (hooked).The shortest distance from the acromion to the humeral head (A-H) was measured.Then the location of subacromial impingement was observed and the thickness of the anterolateral angle was measured preoperatively.At last,acromioplasty using the chock-block technique was performed in the acromions of types Ⅱ and Ⅲ.Postoperatively,the distance A-H and the thickness of the anterolateral angle were measured again for comparison with the preoperative values.Results According to the Bigliani's classification,7 acromions were type Ⅰ,13 type Ⅱ and 10 type Ⅲ.Subacromial impact occurred only in the anterior acromions of types Ⅱ and Ⅲ.The distance A-H was 0.670 ± 0.035 cm in type Ⅰ acromions,significantly longer than the preoperative values of type Ⅱ (0.506 ±0.029 cm) and type Ⅲ (0.334 ±0.023 cm) (P < 0.05),but showed no significant differences from the postoperative values of type Ⅱ (0.692 ±0.025 cm) and type Ⅲ (0.699 ±0.024 cm) (P > 0.05).The anterolateral angular thickness of type Ⅰ acromions was O.413 ± 0.015 cm,significantly thinner than the preoperative values of type Ⅱ (0.607 ±0.014 cm) and type Ⅲ (0.623 ±0.025 cm) (P < 0.05),but showed no significant differences from the postoperative values of type Ⅱ (0.414±0.035 cm) and type Ⅲ (0.412±0.033 cm) (P> 0.05).Conclusion The chock-block technique used for acromioplasty is effective because it can enlarge the supraspinatus outlet and deter impingement.
RESUMO
Objective To analyze the relevant factors of early warning in emergency patients with high risk of acute sores, explore the application value of transcutaneous oxygen pressure(TcPO2) and transcutaneous carbon dioxide pressure(TcPCO2)monitoring in the early warning of emergency patients with pressure ulcers. Methods This was a study of 186 consecutive emergency patients who were under care in the emergency department. The transcutaneous oxygen/carbon dioxide pressure monitor was used in monitoring the oxygen saturation of the skin of sacrococcygeal region and the chest. Meanwhile,the Braden scale was used in assessing risk factors for pressure ulcers and the receiver operating characteristic curve (ROC curve) was applied to evaluate the early prediction of pressure sore with TcPO 2/TcPCO2 monitor. Results Implementing the logistic regression model with six indicators, this research concluded that TcPO2 CV and PO2 were independent risk factors for the development of Braden scale in patients with high risk. The area under the ROC curve showed that TcPO2 CV had a excellent predictive value for the high-risk group and determined its cut-off value to be 20%. Which means patient with both a value of TcPO2CV over 20% and a high risk of Braden scale had a larger possibility of pressure ulcers. Conclusions TcPO2 CV was an independent risk factor for patients under emergency care to develop pressure ulcers. A value of TcPO2CV over 20%indicated a high risk of pressure ulcers.
