ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

Objective To explore the feasibility of automatic segmentation of clinical target volume(CTV)and organs at risk(OARs)for cervical cancer using AccuLearning(AL)based on geometric and dosimetric indices.Methods Seventy-five CT localization images with manual contouring data of postoperative cervical cancer were enrolled in this study.Sixty cases were randomly selected to trained to generate automatic segmentation model by AL,and the CTV and OARs of the remaining 15 cases were automatically contoured.Radiotherapy plans on the automatic segmentation contours were imported on the CT images of manual contours.The efficiency,Dice similarity coefficient(DSC),Hausdorff distance(HD)and dosimetric parameters were compared between the two methods.Results The time of automatic segmentation was significantly shorter than that of the manual contour(P<0.05).The DSC of all structures were≥0.87.The HD of bowel bag and rectum were about 10 mm,and that of the rest of OARs were less than 5 mm.CTV(D98,V90% ,V95% ,Dmean,HI),bowel bag(V50)and bladder(V50)had significant differences in dosimetric comparison(P<0.05).Conclusion The automatic segmentation model based on AL can improve the efficiency of radiotherapy.Automatic segmentation of OARs has the potential of clinical application,while that of CTV still needs to be further modified.

Objective To evaluate the effect of remimazolam combined with desflurane and flumazenil antagonism for anesthesia during ophthalmic day surgery.Methods This is a prospective randomized controlled trial.A total of 64 patients undergoing elective general anesthesia with laryngeal mask during ophthalmic day surgery were selected and randomly assigned to propofol group(n = 32)and remimazolam group(n = 32).The propofol group was given propofol anesthesia induction and propofol combined with diflurane anesthesia maintenance;the remazolam group was given remazolam anesthesia induction and remazolam combined with diflurane anesthesia maintenance,and flumazenil antagonism was given intravenously at the end of the operation.Continuous intravenous infusion of remifentanil was administered during surgery in both groups.The primary outcome was emergence time.The secondary outcome included changes in intraoperative hemodynamic parameters,extubation time,time to leaving the operating room,duration of postoperative recovery room(PACU)stay,and the occurrence of other perioperative adverse reactions.Results Emergence time,extubation time,and time to leaving the operating room in remimazolam group were significantly shorter than those in group propofol(P<0.05)[(4.11±1.17)vs.(8.64±2.77)min,(4.61±1.11)vs.(9.90±2.81)min and(6.60±2.01)vs.(11.74±3.11)min,respectively].The incidences of intraopera-tive hypotension and bradycardia in the remimazolam group were significantly lower than that in the propofol group(P<0.05);There was no statistically difference in the duration of PACU stay and the incidence of postoperative complications between the two groups(P>0.05).Conclusion Remimazolam combined with desflurane general anesthesia and flumazenil antagonism for anesthesia management in ophthalmic day surgery could significantly shorten the time of emergence and extubation,help to maintain hemodynamic stability with fewer adverse reactions,and improve the safety of ophthalmic daytime surgery,which is worthy of clinical promotion and application.

Objective To explore the correlation between intestinal dose and acute radiation enteritis(ARE)in patients with cervical cancer received concurrent chemoradiotherapy,and optimize the dose limit of intestinal tissue.Methods 158 cervical cancer patients received concurrent chemoradiotherapy from 2014 to 2019 were selected in this study.According to CTCAE 5.0,patients with ARE≥grade 2 were classified as ARE≥grade 2 group,otherwise classified as ARE0.7,P<0.05).Conclusions For patients with cervical cancer received concurrent chemoradiotherapy,the dose of bowelbag V5 and V40 should be considered to rationally optimize the dose of bowelbag in the radiotherapy plan,so as to reduce the incidence of ARE≥grade 2.

BACKGROUND:There is currently no anatomic locking plate suitable for the anteromedial platform,so the medial locking plate of the tibial plateau is usually placed forward to fix anteromedial compression fractures caused by hyperextension varus injury.Due to the inability of the locking screw to achieve vertical fixation of the fracture line,coupled with the influence of the patellar ligament,the clinical results are still unsatisfactory. OBJECTIVE:To compare the biomechanical performance of a new type of plate with traditional internal fixation methods in treating hyperextension varus tibial plateau fractures through finite element analysis. METHODS:CT data of 20 cases of hyperextension varus tibial plateau fractures were collected,and their morphological characteristics,such as medial posterior tibial slope,the medial articular fracture angle,surface area,and anterior cortical height were measured.A 24-year-old male volunteer with a height of 175 cm and a weight of 65 kg was selected,and his tibial CT data were imported into Mimics 21.0 software to generate a 3D model.Then,internal fixation models were imported into SolidWorks 2017 software.New type of plate,medial locking plate,posterior medial locking plate,and 6.5 mm hollow screws fixed data models were established based on the measured morphological data.Ansys 17.0 software was used to load stress on the four fixation models and compare their biomechanical performance. RESULTS AND CONCLUSION:(1)With the increase of axial load,the peak stresses of different internal fixation models approximately increased proportionally.At 500 N,the peak stress values were as follows:screw group(6.973 7 MPa)

This consensus considers the original Chinese and English meanings as well as the professional characteristics of terms used in hair transplantation, highlights the unique features and advantages of hair transplantation, and preserves its essence while promoting innovation, with the hope of providing valuable reference for clinical researchers engaged in hair transplantation both domestically and internationally, and better facilitating the standardization and advancement of the field.

Objective:To observe any effect of supplementing basic swallowing training with balloon catheter dilation on the swallowing function of tracheostomy patients with pontine hemorrhage.Methods:A total of 40 pontine hemorrhage patients with tracheostomy and swallowing disorders were divided randomly into an observation group and a control group, each of 20. Both groups were given nutritional neurodrugs and basic swallowing training, but the observation group also received 25 minutes of balloon catheter dilation, five times a week for 6 weeks. Before and after the 6 weeks of treatment one swallowing therapist evaluated the feeding ability and leakage-aspiration status of each subject assigning functional oral intake (FOIS) ratings and Rosenbek Leakage/Aspiration Rating Scale (PAS) ratings double-blinded. The Watian water swallowing test was also applied.Results:After the treatment the average FOIS and PAS scores of both groups had improved significantly, with those of the observation group then significantly better than among the control group on average. The total treatment effectiveness rate was 70% in the observation group, significantly better than the 30% in the control group.Conclusion:Supplementing swallowing training with balloon catheter dilation can better improve the swallowing of patients recovering from a tracheotomy after pontine hemorrhage.

  Objective  To evaluate the effect of intraoperative multimodal analgesia on the early postoperative quality of recovery in end-stage head and neck cancer patients undergoing open gastrostomy surgery.  Methods  This was a prospective, parallel, randomized controlled study. The research subjects were end-stage head and neck cancer patients who underwent elective open gastrostomy at Beijing Tongren Hospital affiliated to Capital Medical University from November 2022 to May 2023. The patients were randomly divided into local anesthesia group and multimodal analgesia group at a 1∶1 ratio. For local anesthesia group, 0.25% ropivacaine 20-30 mL was administered for local infiltration anesthesia. For multimodal analgesia group, the anesthesia method was nerve block + intravenous analgesia: ultrasound-guided left transverse abdominis plane block (0.25% ropivacaine 0.3 mL/kg)+bilateral rectus abdominis sheath block (0.25% ropivacaine 0.3 mL/kg per side)+intravenous injection of oxycodone 0.1 mg/kg, flurbiprofen 1 mg/kg, and dexamethasone 0.2 mg/kg. The primary outcome measure was the quality of requirements-15 (QoR-15) score at postoperative 24 h, while the secondary outcome measures were the QoR-15 score at postoperative 48 h, the numerical rating scale (NRS) and Bruggemann comfort scale (BCS) scores at different time points after the surgery, the first time of rescue analgesia, the first time of off-bed activity and intestinal exhaust, as well as the incidences of adverse reactions within postoperative 48 h.  Results  A total of 46 patients with end-stage head and neck cancer who underwent open gastrostomy and met the inclusion and exclusion criteria were ultimately enrolled, with 23 patients in multimodal analgesia group and 23 patients in local anesthesia group. There was no statistically significant difference in preoperative QoR-15 scores between the two groups (P > 0.05). Multimodal analgesia group had higher QoR-15 scores at 24 h postoperatively[(81.77±8.91) vs. (71.46±7.61), P < 0.05] and 48 h postoperatively[(86.26±7.92) vs. (80.13±6.98), P < 0.05], and the difference in QoR-15 scores at 24 h postoperatively was clinically significant. Compared with local anesthesia group, at 6 h and 24 h after surgery, the multimodal analgesia group showed a decrease in NRS scores at rest and during exercise, while the comfort BCS score increased (all P < 0.05). Multimodal analgesia group also had a delayed time for the first rescue analgesia, a reduced incidence of rescue analgesia within 48 h after surgery, an earlier time for first postoperative off-bed activity and intestinal exhaust (all P < 0.05). The incidence of adverse reactions in multimodal analgesia group and local anesthesia group was 8.70% and 13.04%, respectively, but the difference was not statistically significant (P > 0.05).  Conclusion  Intraoperative multimodal analgesia can effectively alleviate postoperative pain, increase the comfortable degree, shorten the first time of postoperative off-bed activity and intestinal exhaust, and accordingly improve the quality of early postoperative recovery in patients undergoing open gastrostomy.

OBJECTIVE To screen the potential active components of Polygonum orientale flower against myocardial ischemia- reperfusion injury （MIRI） in rats based on physiological and pathological states. METHODS SD rats were divided into normal control group， normal administration group， MIRI control group and MIRI administration group， with 5 rats in each group. After drug intervention or modeling and drug intervention， chromatographic separation plasma samples were collected， and chromatographic separation and mass spectrometry data collection were performed by using UPLC-Q-TOF/MS. The prototype components and metabolites were analyzed by comparing the reference substance maps， the maps of each plasma sample， and the relevant literature. At the same time， the common peaks in plasma samples of rats in normal administration group and MIRI administration group were identified. Combined with principal component analysis and orthogonal partial least square-discriminant analysis， the differential transitional components were screened out according to the value of variable importance in the projection （VIP）＞1， to speculate the potential active components of P. orientale flower in rats under physiological and pathological states. The SD rats were divided into control group， MIRI group， positive control group （Compound danshen tablets 0.2 g/kg， 3 times a day）， and potentially active compound groups （10 mg/kg， twice a day）， with 5 rats in each group. The rats in administration groups were given relevant medicine intragastrically， for 3 consecutive days. The activity of superoxide dismutase （SOD）， the leakages of lactate dehydrogenase （LDH）， creatine kinase isoenzyme-MB （CK-MB） and cardiac troponin Ⅰ （cTnⅠ） in plasma were detected after the last administration. RESULTS Twenty-six main chromatographic peaks were obtained from the total ion chromatogram of the extract of P. orientale flower， and 14 of them were determined， including gallic acid， catechin， protocatechuic acid and so on. There were fifteen （including 6 absorbed prototype components and 9 metabolites） and nineteen transitional components （including 6 absorbed prototype components and 13 metabolites） in the plasma sample of normal rats and MIRI rats. Eight transitional components were detected in both normal rats and MIRI rats， and the VIP values of kaempferol glucuronidation metabolites， quercetin carbonylation metabolites and N-p-paprazine to the corresponding peak were higher than 1. Compared with MIRI group， the activities of SOD were increased significantly in the plasma of MIRI rats in each potential active compound group （P＜0.01）， and the leakages of LDH， CK-MB， and cTnⅠ in the plasma of MIRI rats were reduced significantly （P＜0.01）. CONCLUSIONS The potential anti-MIRI active components in extract of P. orientale flower are N-p-paprazine， quercetin， kaempferol and kaempferol-3-O-β-D-glucoside.
