The blood vessels and nerves of the sole skin of 50 feet of Chinese adult cadavers were observed with an operative microscope. The blood supply of the central part of the sole comes mainly from the medial and lateral plantar ar teries (MPA and LPA). Their average diameter is larger than 2.0mm and their trunk is usually longer than 80mm. When a skin flap is designed, the cutaneous branches from LPA are much better than those from MPA so far as the number of the branches, their external diameter and the extent of the distribution are considered.When the sole skin is stripped away, the cut ends of the cutaneous arteries present a multiple dot-like appearance on the surface of the superficial fascia. The external diameter of the arterial branches, the number of the branches in an unit area, and the total area of the cross section of the branches are different among the regions of the heel and the metatarsal heads, and the central part of the sole. They vary with the weight born on each region.All the cutaneous arteries of the sole are accompanied with veins respectively. Most of the MPA and LPA are accompanied with two veins with a diameter larger than 1.9mm on average. The two veins terminate by joining into two posterior tibial veins.

Objective To analyze the unreasonable elements in prescriptions from outpatient department through the intervention of unreasonable prescriptions;To provide evidence for reasonable usage of medicine in outpatient department.Methods Prescriptions were examined by senior pharmacists. If they found any unreasonable elements, they would consult doctors, and record all the unreasonable elements in the prescriptions to avoid unreasonable prescriptions. A total of 663 unreasonable prescriptions from Jan. 2011 to May 2013 were analyzed.Results A total of 709 unreasonable elements were found in these prescriptions. The man elements were following three types:overdose of toxic decoction pieces (73.76%), incompatible prescriptions without signature (12.13%), wrong inputting of prescription and decoction (7.76%).Conclusion With early intervention in prescriptions, the quality of prescriptions and the safety and effectiveness of medication can be improved.

Objective:To understand the current state of financial toxicity and suicide risk in head and neck cancer patients, to investigate the correlation between the level of financial toxicity and suicide risk in head and neck cancer patients, and to provide a basis for reducing the level of financial toxicity and the risk of suicide in head and neck cancer patients.Methods:A cross-sectional survey was conducted, from March 1 to July 31, 2022, 150 head and neck cancer patients were selected from Oncology Department of East Hospital Affiliated to Tongji Universityby by convenient sampling method. The survey was carried out by means of the general questionnaire, Comprehensive Score for Financial Toxicity based on the Patient-Reported Outcome Measures (COST-PROM), Cancer Suicide Risk Scale (CSRS), and then analysis the datum.Results:The score of COST-PROM of 150 head and neck cancer patients was (18.00 ± 6.12) points, and the score of CSRS of head and neck cancer patients was (36.31 ± 8.51) points. The total score of economic toxicity was significantly negatively correlated with the total score of suicide risk and its dimensions ( r values were -0.446 to 0.235, all P<0.05). The total score of suicide risk was negatively correlated with the total score of economic toxicity and the scores of each dimension ( r values were -0.446 to -0.251, all P<0.05). Conclusions:Patients with head and neck cancer were at higher risk of suicide, and financial toxicity was a significant contributing factor to suicide risk, with higher levels of financial toxicity associated with a higher risk of suicide. Reducing the level of financial toxicity in patients with head and neck cancer has important implications for reducing their risk of suicide.

Mycosin-1 protease (MycP1) is a serine protease anchored to the inner membrane of Mycobacterium tuberculosis, and is essential in virulence factor secretion through the ESX-1 type VII secretion system (T7SS). Bacterial physiology studies demonstrated that MycP1 plays a dual role in the regulation of ESX-1 secretion and virulence, primarily through cleavage of its secretion substrate EspB. MycP1 contains a putative N-terminal inhibitory propeptide and a catalytic triad of Asp-His-Ser, classic hallmarks of a subtilase family serine protease. The MycP1 propeptide was previously reported to be initially inactive and activated after prolonged incubation. In this study, we have determined crystal structures of MycP1 with (MycP1²⁴⁻⁴²²) and without (MycP1⁶³⁻⁴²²) the propeptide, and conducted EspB cleavage assays using the two proteins. Very high structural similarity was observed in the two crystal structures. Interestingly, protease assays demonstrated positive EspB cleavage for both proteins, indicating that the putative propeptide does not inhibit protease activity. Molecular dynamic simulations showed higher rigidity in regions guarding the entrance to the catalytic site in MycP1²⁴⁻⁴²² than in MycP1⁶³⁻⁴²², suggesting that the putative propeptide might contribute to the conformational stability of the active site cleft and surrounding regions.

Objective:To establish and validate the prediction model for postoperative sleep disturbance (PSD) in patients undergoing non-cardiac surgery.Methods:A total of 454 patients of both sexes, aged≥18 yr, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, underwent non-cardiac surgery under general anesthesia from November 2019 to September 2020 were selected.The perioperative data were collected.The patients were divided into training set and validation set with a ratio of 7∶3 by using a simple random sampling method.The characteristic variables of PSD were selected using LASSO regression analysis and the independent risk factors were identified using multivariate logistic regression analysis in training set.Akaike′s information criterion was used to evaluate the quality of fit of the model.The nomogram of PSD in non-cardiac surgery patients was constructed based on the identified factors.The discrimination of the model was evaluated using receiver operating characteristic (ROC) curve, and the agreement of the model was evaluated using Hosmer-Lemeshow goodness-of-fit test and Brier score.Results:Seven risk factors (gender, preoperative anxiety, satisfaction with the ward environment, anesthesia time, the intraoperative consumption of midazolam and sufentanil and numerical rating scale (NRS) score at 3 days after operation) and two related factors (preoperative NRS score and general anesthesia combined with nerve block) were used to establish and verify the PSD nomogram.The area under the ROC curve was 0.805 (95% confidence interval [CI] 0.721-0.848) in training set.The area under the ROC curve was 0.773 (95% CI 0.684-0.876) in validation set.In training and validation sets, the calibration curves were tested by Hosmer-Lemeshow good of fit test, the P values were 0.590 and 0.950, respectively, and the Brier scores were 0.154 and 0.156, respectively.The nomogram predicated that the sensitivity (95% CI) and specificity (95%CI) were 81.83% (60.32%-95.14%) and 78.15% (71.83%-83.25%), respectively, in training set, and the sensitivity (95% CI) and specificity (95%CI) were 77.86% (39.84%-97.25%) and 78.15% 77.86% (68.74%-85.48%), respectively, in validation set.The optimal cut-off value of nomogram score was 113. Conclusion:In this study, the nomogram prediction model for PSD in patients undergoing non-cardiac surgery has been successfully established, which can visually and individually predict the risk of PSD.

ObjectiveTo evaluate the efficacy and safety of Rongjin Tongbi decoction on sciatica caused by lumbar intervertebral disc herniation with liver and kidney deficiency type based on a randomized controlled study. MethodFrom January 2019 to July 2022， 90 patients in the department of Traditional Chinese medicine（TCM） of Beijing Jishuitan Hospital who met the inclusion criteria were selected and divided into two groups according to the random number table， with 45 patients in each group. During the study， 19 cases dropped out， with 41 cases included in the final observation group and 30 cases in the control group. The observation group was given Rongjin Tongbi decoction orally， and the control group was given Loxoprofen Sodium Tablets orally for 28 days. The differences in the visual analog scale （VAS） scores， the Japanese Orthopaedic Association （JOA） scores， activities of daily living （ADL） assessments， TCM clinical symptoms， subjective symptoms， and clinical signs scores between two groups before and after treatment were observed. Liver and kidney functions and gastrointestinal adverse reactions were detected for safety evaluation. ResultBefore treatment， there was no statistically significant difference in scores between the observation group and the control group. After treatment， the absolute values of the differences in VAS and ADL scores in the observation group were higher than those in the control group （P<0.05）. There was no statistically significant difference in the absolute value of the difference in JOA scores between two groups. The absolute value of the difference in TCM clinical symptom scores in the observation group was higher than that in the control group （P<0.01）. There was no statistically significant difference in the absolute values of the differences in subjective symptom and clinical sign scores between two groups. The levels of liver and kidney function indicators in both groups before and after the experiment were normal， and there was no significant difference in gastrointestinal reactions.
