Objective To evaluate the applicability of a modified U-shaped forearm flap for the repair of small-and medium-sized defects in the oral and maxillary areas to provide a reference for clinicians.Methods This study was re-viewed and approved by the Ethics Committee,and informed consent was obtained from the patients.Ten patients with small-and medium-sized defects in the oral and maxillary areas underwent surgical repair using modified U-shaped fore-arm flaps.There were 8 males and 2 females aged 43-72 years.The donor site was apposed primarily after harvesting the modified U-shaped forearm skin flap.The flaps ranged from 6 cm × 4 cm to 8 cm × 5 cm in size.Six months after the operation,hand movements(finger extension,fist clenching,wrist rotation upward and wrist rotation downward),the forearm donor site,hand sensations and the satisfaction score for the postoperative quality of the scar at the donor site were evaluated(0 to 10;0:very unattractive,10:very satisfactory).Results A total of 10 patients with modified U-shaped forearm flaps survived.One patient developed venous crisis 24 hours after surgery and survived after surgical ex-ploration.Delayed healing occurred at the donor site of the forearm in 1 patient,and the wounds at the donor site of the forearm in the other patients all healed in the first stage.One patient presented with dysesthesia in the hand 2 weeks af-ter surgery and recovered within 3 months.Six months after surgery,all patients had no limited hand movement and no paresthesia at the forearm donor site or hand.The patients were basically satisfied with the appearance of the donor site,and the average satisfaction score of the subjective questionnaire was 8.4 points.Conclusion Modified U-shaped fore-arm flaps can directly close forearm donor site wounds,which avoids surgical trauma to the secondary donor site and sig-nificantly reduces related complications.Modified U-shaped forearm flaps provide an alternative to conventional forearm flaps for the repair of small-and medium-sized defects in the oral and maxillary areas.

OBJECTIVE To explore the application effects of the multi-disciplinary treatment （MDT）-based continuous pharmaceutical care system in patients undergoing anti-infection treatment. METHODS This research team innovatively developed an MDT continuous pharmaceutical care system， which was applied to cases of anti-infection treatment following MDT due to infection， aiming to innovate the continuous medication supervision model. A retrospective analysis method was used to collect data from 150 patients in the intensive care unit who underwent conventional anti-infection MDT consultations from January to October 2021 in Banan Hospital Affiliated to Chongqing Medical University， serving as the control group， and 130 patients in the intensive care unit who were under the MDT continuous pharmaceutical care system from January to October 2022 were selected as the intervention group. The general information of the patients， the information continuous tracking management， the outcomes of anti- infection treatment， adverse drug reactions， antibacterial drug management indicators， and the degree of satisfaction of relevant medical staff with the clinical pharmacists’ pharmaceutical services were compared between the two groups. RESULTS Comparison of general information between the two groups showed no statistically significant differences （P＞0.05）. The proportion of continuous tracking management in the intervention group was significantly higher than in the control group （P＜0.01）， and the differences in the initiators and reasons for continuous tracking management between the two groups were statistically significant （P＜0.05）. The intervention group had better outcomes in anti-infection treatment compared to the control group （P＜0.05）. The antibacterial drug management indicators （total length of hospital stay， duration of antibacterial drug use， total drug costs， and amount of antibacterial drugs used） in the intervention group were significantly lower than in the control group， while overall degree of satisfaction among medical staff was significantly higher in the intervention group than in the control group （P＜0.05）. No statistically significant differences were found in adverse reaction occurrence and antibacterial drug costs between the two groups （P＞0.05）. CONCLUSIONS The application of this system in patients who underwent anti-infection treatment after MDT can achieve continuous multi-disciplinary tracking management with clinical pharmacists at the core， which is beneficial for promoting the follow-up efficiency of the MDT team， raising the quality of clinical pharmacists’ pharmaceutical services， strengthening treatment outcomes， and promoting the rational use of antibacterial drugs in clinical practice.

MethodA randomized， double-blind， positive-control， and multi-center clinical trial design method was used. 416 patients with diabetic retinopathy with blood stasis， collateral obstruction， and Qi and Yin deficiency syndrome in four test centers were included （the ratio of the treatment group to the control group was 3∶1）. On the basis of standardized hypoglycemic treatment， the treatment group was given both four Tongluo Mingmu capsules and two Calcium Dobesilate capsule agents three times a day， while the control group were given both two Calcium Dobesilate capsules and four Tongluo Mingmu capsule agents three times a day. The course of treatment was 12 weeks. The curative effect of Tongluo Mingmu capsules was evaluated by comparing the comprehensive curative effect of diabetic retinopathy， traditional Chinese medicine（TCM） syndrome score， corrected visual acuity， fundus changes， fundus fluorescence angiography， and other curative effect indexes before and after treatment in the two groups. At the same time， general examination， laboratory examination， and adverse events were performed to evaluate the safety of the drug. ResultThe baseline demographic data and disease characteristics of the treatment group and the control group were balanced and comparable， with the difference not statistically significant. After 12 weeks of treatment， the total effective rate of the comprehensive curative effect of diabetic retinopathy in the treatment group （61.0%， 189/310） was better than that in the control group （44.1%， 45/102）， and the difference was statistically significant （χ²=8.880， P<0.01）. The total effective rate of TCM syndromes in the treatment group （88.4%， 259/293） was better than that in the control group （69.9%， 65/93）， and the difference was statistically significant （χ²=17.927， P<0.01）. The disappearance rate of dry eyes （χ²=8.305）， dull complexion （χ²=4.053）， lassitude （χ²=10.267）， shortness of breath （χ²=8.494）， and dry stool （χ²=8.657） in the treatment group was higher than that in the control group， and the difference between the groups was statistically significant （P<0.05， P<0.01）. In terms of improving corrected visual acuity （χ²=8.382）， fundus changes （χ²=6.026） ， the treatment group was significantly better than the control group （P<0.05）. During the trial， the incidence of adverse events in the treatment group and the control group was 1.3% and 2.9%， respectively. There was no significant difference between the two groups. In addition， there were no serious adverse events and adverse events leading to withdrawal in both groups. ConclusionTongluo Mingmu capsules can improve the comprehensive curative effect of diabetic retinopathy and enhance the efficacy of TCM syndromes， visual acuity， fundus changes， and fundus fluorescein angiography， with great safety. Therefore， it can provide a new alternative therapeutic drug for patients with diabetic retinopathy.

ObjectiveTo screen out the mRNAs involved in the resistance of hepatoma cells to anlotinib using ceRNA microarray. MethodsHigh-dose shock combined with low-dose induction was used to culture hepatoma cells resistant to anlotinib, and CCK8 assay was used to verify the difference in the proliferation of drug-resistant hepatoma cells treated by anlotinib. The ceRNA microarray was used to screen out the differentially expressed genes between drug-resistant hepatoma cells and normal hepatoma cells, and real-time PCR was used to verify the differentially expressed genes detected by some microarrays. the independent samples t-test was used for comparison of continuous data between two groups, and the Kaplan-Meier method was used to analyze the overall survival of hepatoma cells samples, and the log-rank test was used to compare survival rates. Fisher’s exact test was used for chip screening. ResultsThere was a significant difference in gene expression between drug-resistant hepatoma cells and normal hepatoma cells, and 10 genes with the greatest difference were screened out for analysis by reducing the range. There were 4 genes associated with drug resistance and tumor growth, i.e., BIRC2, BIRC7, ABCC2, and MAPK8. There were significant reductions in the expression levels of BIRC2, ABCC2, and MAPK8 (P=0001 4, 0001 2, and 0.011 8), and there was a significant increase in the expression of BIRC7 (P＜0.001). The results of real-time PCR were consistent with those of microarray (t=10.74,32.65,18.34, and 2.80; P=0.000 4, 0.000 1, 0.000 1, and 0.044 8). The high expression of BIRC7 and the low expression of MAPK8 were associated with the significant reduction in survival time (P=0.022 0 and 0.005 6). ConclusionBIRC2, BIRC7, ABCC2, and MAPK8 are differentially expressed between anlotinib-resistant hepatoma cells and normal hepatoma cells and may be involved in the resistance of hepatoma cells to anlotinib.

Abstract The outbreak of tuberculosis in campus shows a profound impact on academic learning and mental health of students, which might result in more serious social problems. The present editorial addresses weak links in the school tuberculosis prevention and control. Disease prevention and control institutions, medical institutions, education administrative departments and schools need to clarify work responsibilities, strictly implement the school tuberculosis prevention and control laws, regulations and management guidelines, and coordinate with multiple departments, with the aim to strengthen early warning capacity for campus tuberculosis, improve tuberculosis screening and risk assessment of relevant personnel, and implement the health checkup of schools and faculty, as well as the screening, diagnosis, registration, treatment and follow up of students cases. To further improve tuberculosis control across China, strengthening the awareness of tuberculosis prevention and control among institutions and the public, and improving adherence to tuberculosis treatment, as well as moving forward from passive to active tuberculosis monitoring and early prevention, reducing the occurrence of tuberculosis outbreak in school should be prioritized, so as to promote the smooth development of tuberculosis prevention and control work in China.

Brucellosis is a kind of animal epidemic disease that can be transmitted to human beings through skin, mucous membrane, digestive tract, respiratory tract and other ways. In recent years, the incidence of brucellosis has increased. Its pathogenesis is relatively complicated. In addition to bacteria, toxins and other factors, genetic susceptibility has gradually attracted the attention of scholars. In this paper, we summarized the previous reports and reviewed the relationship between interleukin gene polymorphism and susceptibility to brucellosis.
