ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

Objective To explore the predictive value of the expression of serum forkhead box protein M1(FOXM1)and insulin-like growth factor 2(IGF2)on the prognosis of elderly patients with heart failure complicated with pneumonia.Methods A total of 126 elderly patients with heart failure complicated with pneumonia admitted to Handan Central Hospital from March 2021 to June 2022 were included in case group.According to the follow-up results,the 122 patients were grouped into poor prognosis group(n=33)and good prognosis group(n=89).Meanwhile,126 healthy people in the same period were included as the control group.The levels of serum FOXM1 and IGF2,forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1)in the two groups(case group and control group)were measured.Spearman method was used to analyze the correlation between serum levels of FOXM1 and IGF2 and heart function classification in elderly patients with heart failure complicated with pneumonia.The predictive value of serum FOXM1 and IGF2 levels in elderly patients with heart failure complicated with pneumonia was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the levels of FOXM1(2.39±0.55 vs 1.06±0.21)and IGF2(71.33±7.96pg/ml vs 47.82±5.14pg/ml)in the case group were significantly higher(t=25.358,27.581,all P<0.05).Compared with the good prognosis group,the levels of serum FOXM1(3.87±1.06 vs 1.95±0.51)and IGF2(85.88±9.54pg/ml vs 69.14±8.73pg/ml)in the poor prognosis group were significantly higher,and the differences were statistically significant(t=13.453,9.174,all P<0.05).There were significant differences in heart function classification between the good prognosis group and the poor prognosis group,and the differences were statistically significant(χ2=7.120,P<0.05).Compared with the poor prognosis group,FEV1(1.24±0.32 L vs 1.08±0.25 L)and FEV1/FVC(55.46%±5.77%vs 52.30%±5.38%)in good prognosis group were significantly higher,and the differences were statistically significant(t=2.592,2.735,all P<0.05).The levels of serum FOXM1 and IGF2(r=0.496,0.517,all P<0.05)in elderly patients with heart failure complicated with pneumonia were positively correlated with heart function classification.ROC curve results showed that the area under the curve(AUC)of serum FOXM1 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.854(95CI%:0.779～0.912),with sensitivity and specificity of 75.76%and 86.52%,respectively,and the optimal cut-off value of 2.75.The AUC of IGF2 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.874(95CI%:0.802～0.927),with sensitivity and specificity of 72.73%and 85.39%,respectively,and the optimal cut-off value of 78.30 pg/ml.The AUC of the combination of the two in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was greater than the AUC diagnosed by serum FOXM1 alone and IGF2 alone(Z=2.737,2.413,P=0.006,0.016).Conclusion The serum levels of FOXM1 and IGF2 were increased in elderly patients with heart failure complicated with pneumonia,indicating the combined detection of the two may have a high predictive value for the prognosis of patients.

Replacement of the temporomandibular joint (RTJ) has undergone decades of technological improvements and is now an important treatment for end-stage temporomandibular joint (TMJ) disease. The main complications of RTJ include aseptic loosening, heterotopic ossification, postsurgical infection, hypersensitivity reaction, prosthesis loosening or malposition, nerve injury and severe bleeding. Improvement in clinical technique is now the key to resolving complications. In the future, improvements in prosthetic materials may be an important development for newer iterations. With the development and popularity of TMJ surgical techniques, prosthesis-related complications will increasingly come into clinical view. This article provides a systematic review of the complications of RTJ prosthesis replacement and the measures to deal with them, and looks forward to the direction of the development of this field from the perspective of reducing complications, so as to provide a reference for clinical work.

Objective:To understand the commercial homosexual behavior characteristics of men who have sex with men (MSM) and the factors associated with unprotected anal intercourse (UAI) in this population, and provide reference for the development of intervention strategy in MSM.Methods:Men who were aged ≥16 years and had anal sex with men in the past 6 months were recruited through internet in Fuzhou from January to December 2023 for a cross-sectional study with a sample size of 283. Multivariate logistic regression model was used to analyze the factors associated with the incidence of UAI in the past 6 months in MSM. The SPSS 25.0 software was used for statistical analysis.Results:In 4 484 MSM, the proportion of those with commercial homosexual behaviors was 9.59% (430/4 484), the average age was (27.00±9.07) years. In the MSM with commercial homosexual behaviors, 70.00% (301/430) had anal sex in the past one week, and 43.02% (185/430) had anal sex with more than 10 partners in the past 6 months. The proportion of MSM with UAI was 75.58% (325/430) in the past 6 months. The results of multivariate analysis showed showed that in MSM with commercial homosexual behaviors in the past 6 months, compared with those who were students, age >18 years at the first sexual intercourse, had not anal sex in the past one week, and anal sex with less than 10 partners in the past 6 months, the risk for UAI was higher in those who were not students (a OR=1.99,95% CI:1.18-3.36), those who were aged ≤18 years at first sexual intercourse sex (a OR=2.04,95% CI:1.26-3.29), those who had anal sex in the past one week (a OR=2.04,95% CI:1.25-3.33), and those who had anal sex with more than 10 partners in the past 6 months (a OR=1.97,95% CI:1.16-3.35). Conclusions:The risk for UAI was high in MSM with commercial homosexual behaviors in Fuzhou, so it is necessary to improve the awareness of safe sex and promote sex with regular partners and condom use, and preventing drug abuse in MSM.

Peripherally-induced movement disorders (PIMD) are a group of involuntary movements that emerge after an injury to a body part outside the central nervous system. The phenomenology of PIMD encompasses both hyperkinesia and hypokinesia involving multiple parts of the body. The diagnosis of this disease mainly relies on the temporal and spatial relationship between peripheral injuries and movement disorders. The etiology, pathogenesis and treatment of PIMD have been a matter of debate. This article will review the clinical features, classification, diagnosis, treatment and possible pathogenesis of PIMD, and discuss the limitations and controversies of PIMD-related researches, aiming to advance the understanding of PIMD and avoid clinical misdiagnosis.

Objective To analyze the effects of extended subxiphoid thymus resection on inflammatory factors,T lymphocyte subsets and stress response in thymoma patients.Methods The clinical data of 118 patients with thymoma admitted to our hospital from May 2021 to May 2023 were retrospectively analyzed,of which 61 patients underwent subxiphoid enlargement thymectomy(recorded as the study group)and 57 patients underwent lateral thoracotomy enlargement thymectomy(recorded as the control group).The postoperative and perioperative pain,stress response,inflammatory response,T lymphocyte subsets and complications were compared between the two groups.Results There was no significant difference in operation time,intraoperative blood loss and postoperative drainage volume between the two groups(P＞0.05).The visual analogue scale(VAS)of the study group(3.21±0.47,2.47±0.34 points)was lower than that of the control group(3.62±0.53,2.61±0.39 points)at 24 h and 48 h after surgery(P＜0.05).The levels of adrenaline(Adr)and cortisol(Cor)48 h after operation were higher than those before operation(P＜0.05).The levels of Adr and Cor[(101.94±12.83)ng/L,(276.84±31.05)nmol/L]in the study group were lower than those in the control group[(108.15±14.72)ng/L,(308.91±35.24)nmol/L]48 hours after operation(P＜0.05).The levels of TNF-α and IL-6 48 h after surgery were higher than those before surgery(P＜0.05).The levels of tumor necrosis factor a(TNF-α)and interleukin-6(IL-6)in the study group[(40.91±6.93)pg/ml,(55.62±8.67)pg/ml]48 h after surgery were lower than those in the control group[(45.85±8.12)pg/ml,(61.98±10.51)pg/ml](P＜0.05).The levels of Thl/Th2 and Th17/Treg in both groups 48 h after surgery were lower than those before surgery(P＜0.05).The levels of Th1/Th2 and Th17/Treg in the study group(4.75±0.74,0.95±0.17)were lower than those in the control group(5.16±0.89,1.06±0.19)48 h after surgery(P＜0.05).The changes of Th1/Th2 and Th17/Treg in two groups were different(P＜0.05).Conclusion Compared with lateral thoracotomy,transxiphoid enlargement of thymus can reduce perioperative pain,inhibit perioperative inflammatory response and stress response,improve T lymphocyte subpopulation,and is safe and reliable.

Objective:To evaluate the effect of continuous positive airway pressure (CPAP) ventilation during induction of anesthesia on perioperative atelectasis and oxygenation in elderly patients.Methods:Forty-six elderly patients of either sex, aged 65-80 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective cerebrovascular intervention surgery under general anesthesia, were divided into 2 groups ( n=23 each) according to the random number table method: control group (group C) and CPAP ventilation group (group CPAP). During induction of anesthesia, CPAP was set at 5 cmH 2O during spontaneous breathing, and PEEP was set at 5 cmH 2O when spontaneous breathing disappeared, and the ventilation mode was changed to pressure-controlled ventilation (PCV) mode in group CPAP. CPAP was not set, and PEEP was set at 0 cmH 2O for PCV when spontaneous breathing disappeared in group C. During anesthesia maintenance, PCV-volume guaranteed mode was used in both groups, and PEEP was set at 5 cmH 2O. Whole lung CT scanning was performed immediately after radial artery catheterization (T 0), at 1 min after endotracheal intubation (T 1), and before tracheal extubation (T 2) at the end of operation to calculate the percentage of atelectasis area at 1 cm above the right diaphragm. At T 0, T 1, T 2 and 30 min after entering postanesthesia care unit (T 3), blood samples from the radial artery were taken to record PaO 2 and PaCO 2 and calculate the oxygenation index (OI). Results:Compared with the baseline at T 0, the percentage of atelectasis area was significantly increased at T 1 and T 2 in two groups ( P<0.05); PaO 2 was significantly increased at T 1 and T 2 and decreased to T 0 level at T 3, OI was decreased at T 1 and T 2 and increased to T 0 level at T 3 in two groups ( P<0.05). Compared with group C, the percentage of atelectasis area was significantly decreased and PaO 2 and OI were increased at T 1 and T 2 in group CPAP ( P<0.05). There was no significant difference in PaCO 2 at each time point between the two groups ( P>0.05). Conclusions:CPAP ventilation during induction of anesthesia can reduce the development of perioperative atelectasis and improve the oxygenation in elderly patients.

Objective:To evaluate the effect of continuous positive airway pressure(CPAP) ventilation strategy during induction of general anesthesia on atelectasis after induction in obese patients.Methods:A total of 86 patients, aged 30-60 yr, with body mass index of 28-35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective cerebrovascular intervention under general anesthesia, were divided into 2 groups ( n=43 each) using a random number table method: CPAP group (group C) and routine group (group R). Group C received CPAP 5 cmH 2O-assisted ventilation after preoxygenation for spontaneous breathing and disappearance of spontaneous breathing. Chest CT scan and arterial blood gas analysis were performed after entering the operating room (T 1) and 5 min after endotracheal intubation (T 2) to calculate the percentage of atelectasis area and to record PaO 2. Dynamic lung compliance and plateau pressure were recorded at T 2. Mean minute ventilation under controlled breathing, P ETCO 2, and use of vasoactive drugs during induction were recorded. The occurrence of reflux and aspiration during mask ventilation was recorded. The development of pulmonary complications within 3 days after operation was recorded. Results:Compared with group R, the percentage of atelectasis area at T 2 was significantly decreased, PaO 2, dynamic lung compliance and plateau pressure were increased ( P<0.05), and no significant change was found in mean minute ventilation, P ETCO 2, requirement for vasoactive drugs and incidence of pulmonary complications in group C ( P>0.05). No reflux or aspiration was observed during mask ventilation. Conclusions:CPAP (5 cmH 2O) strategy during anesthesia induction can reduce the degree of atelectasis after induction in obese patients.

Objective:To explore the effect of spontaneous breathing during induction of general anesthesia on atelectasis in patients undergoing laparoscopic resection of gastrointestinal tumors.Methods:A total of 60 patients aged 18-60 years scheduled for laparoscopic resection of gastrointestinal tumors under general anesthesia in the First Hospital of Shanxi Medical University from October 2021 to August 2022 were selected. The body mass index was 18.5-28.0 kg/m 2 and the American Society of Anesthesiology grade wasⅠ-Ⅱ. All patients were divided into the spontaneous breathing group (group S, 30 cases) and the controlled breathing group (group C, 30 cases) according to the random number table method. Patients in group S received 0.2-0.3 mg/kg etomidate (pumping at the speed of 200 ml/h) and 2 μg/kg remifentanil (slowly injected more than 30 s) for anesthesia induction; patients in group C received 0.2-0.3 mg/kg etomidate and 2 μg/kg remifentanil (slowly injected more than 30 s) and 0.2 mg/kg cisatracurium. After bispectral index (BIS) decreased to 80, the patients had no response to the language stimulation; and then the mask was used to closely fit the face and maintain spontaneous breathing in group S; patients in group C received manual positive pressure ventilation. Atelectasis scores were collected immediately after endotracheal intubation (T 1) and 15 min after transferring to the recovery room (T 3), and oxygenation index (OI) was collected 5 min after endotracheal intubation (T 2) and at T 3. The postoperative pulmonary complication (PPC) on the 3rd day after the operation was recorded. Results:A total of 56 patients were finally enrolled, 27 cases in group S and 29 cases in groups C. Compared with group C, the atelectasis score of group S at T 1 and T 3 decreased [T 1: (2.4±0.8) scores vs. (4.2±0.7) scores, t = -9.12, P < 0.001; T 3: (8.2±1.8) scores vs. (10.5±1.6) scores, t = -4.96, P < 0.001]. The OI increased at T 2 and T 3 in group S [T 2: (334±11) mmHg (1 mmHg = 0.133 kPa) vs. (323±13) mmHg, t = 3.45, P = 0.001; T 3: (362±23) mmHg vs. (347±25) mmHg, t = 2.31, P = 0.025]. The incidence of PPC was 20.7% (6/29) and 18.5% (5/27), respectively in group C and group S on the 3rd day after the operation, and the difference was statistically significant ( χ2 = 0.04, P = 0.838). Conclusions:Maintaining spontaneous breathing during induction of general anesthesia can reduce atelectasis caused by general anesthesia and improve oxygenation for patients undergoing laparoscopic resection of gastrointestinal tumors.

Objective    To compare clinical effects of enlarged thymectomy for the treatment of myasthenia gravis (MG) complicated with thymoma via subxiphoid and subcostal arch thoracoscopic resection versus median sternotomy resection. Methods    We retrospectively analyzed the clinical data of patients with MG complicated with thymoma admitted in Tangdu Hospital of the Air Force Military Medical University between December 2011 and December 2021. Patients who underwent subxiphoid and subcostal arch thoracoscopic enlarged thymectomy were allocated to a SR group, and patients who underwent median sternotomy enlarged thymectomy were allocated to a MR group. Perioperative outcomes were compared between the two groups. Results    A total of 456 patients were collected. There were 51 patients in the MR group, including 30 males and 21 females aged 23-66 (49.5±11.8) years. There were 405 patients in the SR group, among whom 51 patients were matched to the MR group by propensity score matching, including 28 males and 23 females aged 26-70 (47.2±12.2) years. The operations were accomplished successfully in all patients, and no conversion to thoracotomy occurred in the SR group. The SR group had advantages in the operation time, intraoperative blood loss,  chest drainage duration, hospital stay time, patients’ satisfaction level, pain score and complications (all P<0.05). No statistical difference was found in the number of intraoperative lymph node dissection stations, number of intraoperative lymph nodes dissected or remission of MG between the two groups (P>0.05). Conclusion    Subxiphoid and subcostal arch thoracoscopic enlarged thymectomy and lymphadenectomy is a safe, effective and feasible minimally invasive procedure for the treatment of MG complicated with thymoma.
