Objective:To evaluate the safety of ensartinib in the treatment of anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) in the real-world clinical setting.Methods:Clinical data of 2 221 patients with ALK-positive locally advanced or metastatic NSCLC who received ensartinib treatment (225 mg/d) from December 16, 2020 to December 16, 2021 were collected and analyzed to assess drug adverse reactions in all population including elderly patients (≥ 65 years old) .Results:Among the total 2 221 patients, 511 patients (23.01%) experienced adverse events, including 8 patients (0.36%) who experienced serious adverse events. Adverse events led to dose modification in 67 patients (3.02%) and discontinuation in 18 patients (0.81%). The common adverse events were rash (407/2 221, 18.33%), pruritus (41/2 221, 1.85%), constipation (41/2 221, 1.85%), and facial edema (31/2 221, 1.40%). Thirty-six patients (1.62%) experienced ≥grade 3 adverse events. After symptomatic treatment of 511 patients with adverse reactions, 50 patients (9.78%) were healed, 271 patients (53.03%) were improved, 120 patients (23.48%) were persisted, and 70 patients (13.71%) were unknown due to loss of follow-up or other reasons. Forty-three patients (1.94%) reported 57 unintended adverse reactions. Among the 599 elderly patients, 116 patients (19.37%) experienced adverse events, including 1 patient (0.17%) who experienced serious adverse events. Adverse events led to dose modification in 25 patients (4.17%) and discontinuation in 5 patients (0.83%). The common adverse events of elderly patients were rash (88/599, 14.69%), constipation (14/599, 2.34%), facial edema (12/599, 2.00%), and pruritus (10/599, 1.67%). Twelve patients (2.00%) experienced ≥grade 3 adverse events. Among the 116 elderly patients with adverse reactions following the symptomatic treatment, 11 patients (9.48%) were healed, 58 patients (50.00%) were improved, 28 patients (24.13%) were persisted, and 19 patients (16.39%) were unknown due to loss of follow-up or other reasons. During the treatment, 1 patient (0.05%) experienced grade 2 interstitial lung disease, and no patient died due to adverse events.Conclusion:Ensartinib has a favorable safety profile in the real-world populations, with the most frequent adverse events being rash, mostly mild, and low incidence of ≥grade 3 adverse events. Overall, adverse reactions were tolerable and manageable.

Objective:To compare the effects of anterograde elastic stable intramedullary nailing (ESIN-A), retrograde K-wires fixation (KW-R) and retrograde precision shaping of elastic stable intramedullary nailing (ESIN-RPS) in the treatment of fractures of distal radial metaphyseal diaphyseal junction (DRMDJ) in children.Methods:A retrospective study was conducted to analyze the data of 112 eligible children with DRMDJ fracture who had been treated at Department of Orthopedics, Children's Hospital, Anhui Medical University and Department of Orthopedics, The People's Hospital of Fuyang City,Anhui Medical University, from January 2016 to May 2022. There were 64 males and 48 females, with an age of (8.4±2.3) years. The children were divided into 3 groups according to different surgical fixation methods: group ESIN-A of 36 cases, group KW-R of 52 cases, and group ESIN-RPS of 24 cases. The operation time, intraoperative bleeding, fluoroscopy times, alignment rates and residual angulations by the anteroposterior and lateral X-ray films immediately after reduction were compared among the 3 groups. The Gartland-Werley evaluation of wrist function and complications were compared at the last follow-up.Results:There was no statistically significant difference in the preoperative general data among the 3 groups, indicating comparability ( P>0.05). In the operation time, group KW-R [(71.2±9.2) min] > group ESIN-A [(65.1±13.1) min] > group ESIN-RPS [(51.7±17.1) min]; in the fluoroscopy times, group KW-R [(13.9±6.3) times] > group ESIN-A [(9.0±2.8) times] > group ESIN-RPS [(6.4±2.0) times]; in the alignment rates by the anteroposterior and lateral X-ray films immediately after reduction, group ESIN-RPS (93.1%±4.6% and 95.2%±3.3%) > group KW-R (82.1%±11.0% and 88.1%±7.4%) > group ESIN-A (80.4%±9.9% and 86.7%±6.9%); in the residual angulations by the anteroposterior and lateral X-ray films immediately after reduction, group ESIN-RPS (3.3°±1.8° and 2.9°±2.1°) < group ESIN-A (5.2°±1.0° and 5.0°±3.2°) < group KW-R (6.6°±1.6°and 7.5°±2.7°). Pairwise comparisons in the above items were statistically significant ( P<0.05). In group ESIN-A, the incision length [(1.8±0.3) cm] was significantlylonger than that in group ESIN-RPS [(1.4±0.2) cm], and the intraoperative blood loss [(8.3±2.2) mL] significantly larger than that in group ESIN-RPS [(5.5±1.6) mL] ( P<0.05). One year after operation, the excellent and good rate by the Gartland-Werley evaluation of wrist function in groups ESIN-RPS, ESIN-A and KW-R, respectively, were 95.8% (23/24), 86.5% (31/36) and 86.1% (46/52), showing no statistically significant difference between the 3 group ( P>0.05), and the major incidence of complications in group KW-R (25.0%, 13/52) and in group ESIN-A (25.0%, 9/36) were significantly higher than that in group ESIN-RPS (4.2%, 1/24) ( P<0.05). Conclusion:In the treatment of DRMDJ fractures in children, compared with ESIN-A and KW-R, ESIN-RPS is an effective choice due to its advantages of shorter operation time, less intraoperative blood loss, less radiation, better alignment, and fewer complications.

OBJECTIVE: To investigate the short-term effectiveness of ultrasound-guided closed reduction by Kirschner wire provocation technique in the treatment of Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents. METHODS: Between May 2019 and May 2022, 41 patients with Salter Harris types Ⅰ and Ⅱ distal tibial epiphyseal fractures were admitted, all of whom had periosteal entrapment on preoperative MRI, and 38 cases (92.7%) were confirmed to have periosteal entrapment by intraoperative ultrasound. There were 24 males and 14 females, the age ranged from 6.8 to 15.7 years, with an average of 10.7 years; and there were 20 cases of Salter Harris type Ⅰ and 18 cases of type Ⅱ. The time from injury to operation was 22-76 hours, with an average of 28.4 hours. The preoperative imaging examination showed excellent alignment in 4 cases, good in 20 cases, and poor in 14 cases. The ultrasound guided Kirschner wire provocation technique for closed reduction and percutaneous Kirschner wire internal fixation were performed. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Anteroposterior and lateral X-ray films of the affected ankle joint were taken before operation, at 3 months after operation, and at last follow-up to observe the healing of the fracture, and anteroposterior X-ray films of the whole length of both lower limbs were taken to evaluate the alignment of the force lines of the affected limbs. The range of motion (ROM), visual analogue scale (VAS) score, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used to evaluate ankle function. The mechanical lateral distal tibia angle (mLDTA) and the anatomic anterior distal tibia angle (aADTA) were measured. RESULTS: The operation time ranged from 17 to 52 minutes, with an average of 22.6 minutes, and the intraoperative fluoroscopy frequency ranged from 3 to 11 times, with an average of 4.2 times. X-ray examination during operation and at 2 days after operation showed that anatomical reduction was achieved. All patients were followed up 10-24 months, with an average of 16.4 months. All fractures healed in 6.1-7.2 weeks, with an average of 6.3 weeks; no fracture displacement occurred, and the patients recovered to their pre-injury level of motion at 6 months after operation. Needle tail irritation occurred in 2 cases at 4 weeks after operation, and they recovered after symptomatic treatment. During the follow-up, there was no serious complication such as incision deep infection, bone nonunion, delayed union, and malunion. At last follow-up, the patients' alignment were all excellent, and the difference was significant when compared with preoperative one ( Z=-7.471, P<0.001). The VAS score, AOFAS ankle-hindfoot score, dorsiflexion-plantar flexion ROM, varus-valgus ROM, mLDTA, and aADTA significantly improved at 3 months after operation and last follow-up when compared with preoperative ones ( P<0.05). CONCLUSION Ultrasound-guided closed reduction by Kirschner wire provocation technique for treating Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents is minimally invasive and safe.

OBJECTIVE: To investigate the effectiveness of medial and lateral column periosteal hinge reconstruction using Kirschner wire in the closed reduction of multi-directional unstable humeral supracondylar fractures in children. METHODS: A clinical data of 43 children with multi-direction unstable humeral supracondylar fractures, who met the selection criteria and were admitted between August 2020 and August 2022, was retrospectively analyzed. Twenty-one cases of fractures were treated wuth closed reduction after medial and lateral column periosteal hinge reconstruction using Kirschner wire and percutaneous Kirschner wires fixation (study group), while 22 cases of fractures were treated by traditional closed reduction technique and percutaneous Kirschner wire fixation (control group). There was no significant difference in gender, age, cause of injury, fracture side, and interval from injury to operation between the two groups ( P>0.05). The operation time, intraoperative fluoroscopy times, the number of children who were changed to open reduction after closed reduction failure, fracture healing time, complications within 2 months after operation, and the Flynn score of elbow joint function at last follow-up were compared between the two groups. RESULTS: All the fractures in the study group were successfully closed reduction, and 4 cases in the control group were changed to open reduction and completed the operation, the difference between the two groups was significant ( P=0.040). The operation time and intraoperative fluoroscopy times of the study group were significantly less than those of the control group ( P<0.05). All children in both groups were followed up 6-18 months with an average of 9.0 months in the study group and 9.8 months in the control group. Imaging review showed that the fractures of both groups healed, and the difference in the healing time between the two groups was not significant ( P=0.373). According to Flynn score at last follow-up, the excellent and good rate of elbow joint function was 95.2% (20/21) in the study group and 86.4% (19/22) in the control group, with no significant difference ( P=0.317). There was no complication such as infection or irritation at the end of Kirchner wire within 2 months after operation. CONCLUSION For children with multi-directional unstable humeral supracondylar fractures, the use of Kirschner wires to reconstruct the medial and lateral column periosteal hinge to assist in closed reduction has the advantages of shortening operation time, reducing intraoperative fluoroscopy times, and effectively reducing the incidence of open reduction, and can achieve similar postoperative elbow joint function when compared with traditional closed reduction technique.

Objective:To observe the effects of different kinesio taping methods on hand swelling, shoulder pain, upper limb motor function and ability in the activities of daily living of stroke survivors with shoulder-hand syndrome.Methods:Sixty stroke survivors with shoulder-hand syndrome were randomly divided into groups A, B, C and a control group, each of 15. In addition to routine rehabilitation training and drug treatment, as well as claw-shaped and I-shaped taping of the hand and wrist, group A received I-shaped kinesio taping, B received Y-shape and C received I-shape plus Y-shaped taping of the shoulder. Before and after 4 weeks, the drainage method was employed to calculate the difference in volume between the two hands. Their temperatures were also measured. The subjects reported shoulder pain using a visual analog scale (VAS). Upper limb motor functioning was quantified using Fugl-Meyer scores, and difficulties in the activities of daily living were evaluated using the modified Barthel index (MBI).Results:Before the treatment there were no significant differences among the four groups in terms of any of the measurements. Afterward the treatment, significant improvement was observed in the volume and temperature differences between hands, as well as in the VAS, FMA and MBI scores. After the treatment, group C′s average FMA score was significantly higher than those of the other groups. There was no significant difference in MBI scores among the four groups.Conclusions:Supplementing rehabilitation training with I-shaped plus Y-shaped kinesio taping can effectively reduce the volume and temperature differences between the hands, relieve shoulder pain, and improve effectiveness in the activities of daily living of persons with shoulder-hand syndrome after a stroke. Hand-claw and wrist-I taping also have some effect.

Objective:To compare the effects of two pretreatment schemes on the efficacy, gonad and reproductive function of haploid hematopoietic stem cell transplantation recipients with severe aplastic anemia(SAA).Methods:The data of 73 patients with SAA who underwent haploid hematopoietic stem cell transplantation were analyzed retrospectively.The pretreatment scheme was divided into Fludarabine+ Cyclophosphamide+ Antithymocyte globulin group(FC lowATG group, 45 cases)and Busulfan+ Cyclophosphamide+ Antithymocyte globulin group(Bucy/ATG group, 28 cases). The changes of blood cell implantation time, follicle stimulating hormone(FSH), luteinizing hormone (LH), estradiol and testosterone were compared between the two groups. Results:there was no significant difference in blood cell implantation time between the two groups( P=0.096; P=0.133). The levels of FSH and LH in female recipients in Bucy/ATG group were higher than those in FC lowATG group, and the level of estradiol was lower than that in FC lowATG group.There were significant differences between the groups(all P<0.05). The pregnancy or fertility rate of female recipients in Bucy/ATG group was lower than that in FC lowATG group(all P<0.05). There was no significant difference in FSH, LH, testosterone and fertility between the two groups(all P>0.05). There was no significant difference in 2-year overall survival rate and failure free survival rate between the two groups( P=0.091; P=0.084). Conclusions:FC lowATG may be an effective pretreatment scheme for haploid hematopoietic stem cell transplantation in SAA with less damage to gonad and reproductive function.

Objective:To evaluate the efficacy and safety of modified FC/ATG pretreatment in the treatment of severe aplastic anemia(SAA).Methods:From June 2012 to June 2020, clinical data of 64 patients with severe aplastic anemia undergoing allogeneic hematopoietic stem cell transplantation with modified FC/ATG(Flu 30 mg·m -2·d -l, -5~-2 d、CTX 50 mg·kg -1·d -1~-2 d、ATG: 2.5 mg·kg -1·d -1, -5~-2 d) pretreatment were retrospectively analyzed.There were MSD-HSCT ( n=29) and Haplo-HSCT ( n=35). Results:One patient died of intracerebral hemorrhage before transplantation and the remainders were completely implanted.During a median follow-up period of 14.5(1-95) months, overall survival (OS) rate of 92.2%.It was significantly higher than OS rate of 67.2% in the treatment of SAA by foreign pretreatment regimens containing low-dose TBI.And pretreatment scheme containing FC+ BU/TBI had an OS of slightly >91.3% in the treatment of SAA.The 3-year OS rates were 85.7% and 93.5% in Haplo-HSCT and MSD-HSCT groups ( P=0.058). The OS rate of SAA Haplo-HSCT/MSD-HSCT group was similar to that of " Beijing Protocol" (BU/CY+ ATG) (89%, 91%). The viral infection rates of EB and CMV were significantly higher in haplo-HSCT group than those in MSD-HSCT group and inter-group difference was statistically significant ( P<0.05). However, univariate analysis showed that two groups had no effect on survival time ( P=0.403, P=0.132). Univariate analysis showed that survival time was significantly associated with the presence of Ⅲ-Ⅳ° aGVHD and the presence of severe complications ( P=0.007, P=0.001). Further multivariate analysis revealed that severe complication was an independent risk factor for survival ( P=0.003). Conclusions:The efficacy of improved FC/ATG pretreatment in the treatment of SAA in MSD-HSCT or Haplo-HSCT is higher than other domestic and international pretreatment schemes in OS rate, safety and effectiveness.Onset of severe complication and association with Ⅲ ~ Ⅳ ° aGVHD are the influencing factors for patient survival.The efficacy of Haplo-HSCT group is similar to that of MSD-HSCT group.It may be employed as an alternative donor for SAA patients without fully congruent donors.

[Abstract] Objective: To construct and verify the anti-tumor activity of chimeric antigen receptor (CAR) modified NK-92 cells (CAR-NK-92 cells) targeting prostate stem cell antigen (PSCA) in cervical cancer. Methods: Lentiviral vector expressing CAR targeting PSCA was constructed, and PSCA CAR-NK-92 cells were obtained by lentivirus transfection. The expression of PSCA in human cervical cancer cells was determined by Flow cytometry and Western blotting. The killing effect of PSCA CAR-NK-92 cells against cervical cancer cells was verified by co-incubation of effector and target cells in vitro, and the tumor inhibitory ability of PSCA CAR-NK-92 cells was verified with the nude mice xenograft model in vivo. Results: PSCA CAR-NK-92 cells were successfully constructed. PSCA was highly expressed in human cervical cancer Hela and MS751 cells (all P<0.01). In vitro co-incubation results showed that PSCA CAR-NK-92 cells could lyse PSCA+ cervical cancer transplanted tumor in a dose-dependent manner. In vivo anti-tumor data showed that PSCA CAR-NK-92 cells significantly inhibited the growth of cervical cancer cells compared with NK-92 cells transfected with vehicle vectors (P<0.01). In addition, PSCA CAR-NK-92 cells could effectively infiltrate tumor tissues and promote the secretion of anti-tumor cytokines TNF-α and IFN-γ (all P<0.01). Conclusion: The CAR-NK-92 targeting PSCA shows good anti-tumor effect on PSCA+ tumor cells both in vitro and in vivo, and has potential to be a therapeutic strategy for cervical cancer.

OBJECTIVETo investigate the effect of aloin on apoptosis of human gastric cancer cells and explore the molecular mechanism.

METHODSGastric cancer MKN-28 and HGC-27 cells were cultured routinely in 1640 medium supplemented with 10% fetal bovine serum and 10% non-essential amino acids (for HGC-27 cells) and treated with different concentrations of aloin for different durations. The cell viability, cell nuclear morphology, and apoptotic rate of the cells were detected using CCK-8 assay, DAPI staining and AnnexinV-FITC/PI, respectively; Western blotting was used to detect the expression levels of PARP, procaspase 3 and the phosphorylation of p38, ERK and JNK. The cells were treated with specific inhibitors of p38, ERK and JNK, and the inhibitory effects on these pathways were detected with Western blotting; DAPI staining was used to detect the effects of inhibitors on apoptosis of gastric cancer cells.

RESULTSAloin dose-dependently inhibited the viability and induced apoptosis of HGC-27 and MKN-28 cells. Alion treatment obvious enhanced the phosphorylation of p38 and JNK but decreased ERK phosphorylation in the cells. Blocking ERK activation with the ERK inhibitor obviously enhanced aloin-induced cell apoptosis, where inhibiting p38 and JNK activation partly reversed alion-induced apoptosis in the cells.

CONCLUSIONSAloin induces apoptosis of human gastric cancer cells by activating p38 and JNK signaling pathways and inhibiting ERK signaling pathway.

STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the clinical efficacy and feasibility of one-stage anterolateral debridement, bone grafting, and internal fixation for treating lumbosacral tuberculosis. OVERVIEW OF LITERATURE: There has been no consensus regarding the optimal means of treating lumbosacral tuberculosis. The one-stage anterolateral extraperitoneal approach for radical debridement, bone grafting, and internal fixation for treating lumbosacral tuberculosis is rare in literature. METHODS: Twenty-one patients with lumbosacral tuberculosis were retrospectively analyzed. All patients underwent the surgery of anterolateral debridement after regularly antituberculous drugs therapy. We evaluated the erythrocyte sedimentation rate, C-reactive protein, radiography, computed tomography, magnetic resonance imaging, visual analogue score, and Oswestry disability index before and after surgery. RESULTS: All patients completed a follow-up survey 9–48 months after surgery. All patients' wounds healed well without chronic infection or sinus formation, and all patients with low-back pain reported relief after surgery. All cases had no tuberculosis recurrence. Solid bony fusion was achieved within 6–12 months. At final follow-up, evaluated the erythrocyte sedimentation rate decreased from 38.1±12.5 to 11.3±7.1 mm/hr, C-reactive protein decreased from 6.2±4.2 to 1.6±1.3 mg/dL, the visual analog scale score decreased from 4.6±1.1 to 1.4±1.0, the Oswestry disability index score decreased from 50.2%±11.9% to 13.0%±6.6%, and the lumbosacral angle increased from 20.0°±4.8° to 29.0°±3.9° (p<0.05). CONCLUSIONS: One-stage anterolateral debridement, bone grafting, and internal instrument fixation for treating lumbosacral tuberculosis is safe and effective.
