Acupuncture Combined with Auricular Acupoints Patches for Moderate to Severe Nicotine Dependence：a Randomized Controlled Study / 中医杂志

ObjectiveTo compare the efficacy and safety of acupuncture combined with auricular acupoints patches and nicotine transdermal patch in treating moderate to severe nicotine dependence. MethodsIn a rando-mized controlled trial， 64 quit smoking voluntary subjects with moderate to severe nicotine dependence were randomly divided at a ratio of 1∶1 into a treatment group and a control group， with 32 cases in each group. The treatment group was given acupuncture combined with auricular acupoints patches， twice weekly， four weeks as a course for two courses. The control group was given nicotine transdermal patch， one patch per day for 24 hours， 8 weeks. The cure rate was assessed after treatment and at follow-up （the 16th week after treatment）.The daily smoking volume， exhaled carbon monoxide （CO） value， Nicotine Dependence Scale （FTND）， Minnesota Nicotine Withdrawal Symptoms Scale （MNWS）， and Pittsburgh Sleepiness Index Inventory （PSQI） were evaluated before and after treatment and at follow-up， and adverse effects were recorded. ResultsIn terms of the cure rate， there were both six cured cases （20%） after treatment and at follow-up in the treatment group， while in the control group， seven （23.3%） and five （16.7%） patients were cured after treatment and at follow-up， respectively， with no statistically significant differences between the two groups both after treatment and at follow-up （P＞0.05）. The daily smoking volume and exhaled CO value significantly decreased after treatment and at follow-up in both groups （P＜0.05）， but were not significantly different between the groups after treatment and at follow-up （P＞0.05）. After treatment and at follow-up， FTND， MNWS， and PSQI scores were significantly reduced in both groups compared with those before treatment （P＜0.05）. There was no statistically significant difference in the FTND scale scores between the two groups after treatment and at follow-up （P＞0.05）， while the MNWS and PSQI scale scores were lower in the treatment group than in the control group （P＜0.05）. ConclusionAcupuncture combined with auricular acupoint patches for moderate to severe nicotine dependence has comparable effect with the first-line drug nicotine patch in terms of increasing the cure rate and decreasing the degree of nicotine dependence， and is superior to nicotine patch in terms of relieving withdrawal symptoms and improving sleep， with stable long-term effect.

OBJECTIVES@#To study the efficacy and safety of Xiyanping injection through intramuscular injection for the treatment of acute bronchitis in children.@*METHODS@#A prospective study was conducted from December 2021 to October 2022, including 78 children with acute bronchitis from three hospitals using a multicenter, randomized, parallel-controlled design. The participants were divided into a test group (conventional treatment plus Xiyanping injection; n=36) and a control group (conventional treatment alone; n=37) in a 1:1 ratio. Xiyanping injection was administered at a dose of 0.3 mL/(kg·d) (total daily dose ≤8 mL), twice daily via intramuscular injection, with a treatment duration of ≤4 days and a follow-up period of 7 days. The treatment efficacy and safety were compared between the two groups.@*RESULTS@#The total effective rate on the 3rd day after treatment in the test group was significantly higher than that in the control group (P<0.05), while there was no significant difference in the total effective rate on the 5th day between the two groups (P>0.05). The rates of fever relief, cough relief, and lung rale relief in the test group on the 3rd day after treatment were higher than those in the control group (P<0.05). The cough relief rate on the 5th day after treatment in the test group was higher than that in the control group (P<0.05), while there was no significant difference in the fever relief rate and lung rale relief rate between the two groups (P>0.05). The cough relief time, daily cough relief time, and nocturnal cough relief time in the test group were significantly shorter than those in the control group (P<0.05), while there were no significant differences in the fever duration and lung rale relief time between the two groups (P>0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSIONS@#The overall efficacy of combined routine treatment with intramuscular injection of Xiyanping injection in the treatment of acute bronchitis in children is superior to that of routine treatment alone, without an increase in the incidence of adverse reactions.

Effectiveness of preemptive analgesia with imrecoxib on analgesia after anterior cruciate ligament reconstruction: a randomized controlled study / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of preemptive analgesia with imrecoxib on analgesia after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 160 patients with ACL injuries who met the selection criteria and were admitted between November 2020 and August 2021 were selected and divided into 4 groups according to the random number table method (n=40). Group A began to take imrecoxib 3 days before operation (100 mg/time, 2 times/day); group B began to take imrecoxib 1 day before operation (100 mg/time, 2 times/day); group C took 200 mg of imrecoxib 2 hours before operation (5 mL of water); and group D did not take any analgesic drugs before operation. There was no significant difference in gender, age, body mass index, constituent ratio of meniscal injuries with preoperative MRI grade 3, constituent ratio of cartilage injury Outerbridge grade 3, and visual analogue scale (VAS) score at the time of injury and at rest among 4 groups (P>0.05). The operation time, hospitalization stay, constituent ratio of perioperative American Society of Anesthesiologists (ASA) grade 1, postoperative opioid dosage, and complications were recorded. The VAS scores were used to evaluate the degree of knee joint pain, including resting VAS scores before operation and at 6, 24, 48 hours, and 1, 3, 6, and 12 months after operation, and walking, knee flexion, and night VAS scores at 1, 3, 6, and 12 months after operation. The knee injury and osteoarthritis score (KOOS) was used to evaluate postoperative quality of life and knee-related symptoms of patients, mainly including pain, symptoms, daily activities, sports and entertainment functions, knee-related quality of life (QOL); and the Lysholm score was used to evaluate knee joint function.@*RESULTS@#All patients were followed up 1 year. There was no significant difference in operation time, hospitalization time, or constituent ratio of perioperative ASA grade 1 among 4 groups (P>0.05); the dosage of opioids in groups A-C was significantly less than that in group D (P<0.05). Except for 1 case of postoperative fever in group B, no complications such as joint infection, deep vein thrombosis of the lower extremities, or knee joint instability occurred in each group. The resting VAS scores of groups A-C at 6 and 24 hours after operation were lower than those of group D, and the score of group A at 6 hours after operation was lower than those of group C, and the differences were significant (P<0.05). At 1 month after operation, the knee flexion VAS scores of groups A-C were lower than those of group D, the walking VAS scores of groups A and B were lower than those of groups C and D, the differences were significant (P<0.05). At 1 month after operation, the KOOS pain scores in groups A-C were higher than those in group D, there was significant difference between groups A, B and group D (P<0.05); the KOOS QOL scores in groups A-C were higher than that in group D, all showing significant differences (P<0.05), but there was no significant difference between groups A-C (P>0.05). There was no significant difference in VAS scores and KOOS scores between the groups at other time points (P>0.05). And there was no significant difference in Lysholm scores between the groups at 1, 3, 6, and 12 months after operation (P>0.05).@*CONCLUSION@#Compared with the traditional analgesic scheme, applying the concept of preemptive analgesia with imrecoxib to manage the perioperative pain of ACL reconstruction can effectively reduce the early postoperative pain, reduce the dosage of opioids, and promote the early recovery of limb function.

Clinical efficacy of gradual decompression in the treatment of severe traumatic brain injury and its effects on the improvement of intracranial pressure / 中国基层医药

Objective:To investigate the clinical efficacy of gradual decompression in the treatment of severe traumatic brain injury and its effects on the improvement of intracranial pressure.Methods:The clinical data of 120 patients with severe traumatic brain injury who received treatment in the General Hospital of Taiyuan Iron and Steel (Group) Co., Ltd. from January 2015 to January 2020 were retrospectively analyzed. The included patients were divided into decompressive craniectomy group (control group, n = 64) and gradual decompression group ( n = 56). Intracranial pressure was compared between the two groups at different time points (before surgery, during the surgery, immediately after surgery, 3 and 6 months after surgery). The patient's self-care ability, coma degree, and neurological deficits pre-surgery and 6 months after surgery were evaluated in each group. The incidence of complications throughout the surgery and within 6 months after surgery was calculated to evaluate the quality of life. Results:There was no significant difference in intracranial pressure pre-surgery between the two groups ( P > 0.05). Intracranial pressure in the gradual decompression group was (30.74 ± 2.51) mmHg, (25.11 ± 2.06) mmHg, (21.34 ± 2.01) mmHg, and (16.74 ± 1.54) mmHg respectively during the surgery, immediately after surgery, and 3 and 6 months after surgery, which was significantly lower than that in the control group [(34.31 ± 3.06) mmHg, (30.64 ± 2.57) mmHg, (26.33 ± 2.35) mmHg, (22.64 ± 1.95) mmHg, t = 12.88, 19.03, 12.40, 18.20, all P < 0.001]. There were no significant differences in scores of the Modified Barthel Index (MBI), the Glasgow Coma Scale (GCS), the National Institutes of Health Stroke Scale (NIHSS) pre-surgery between the two groups (all P > 0.05). At 6 months after surgery, the MBI and GCS scores increased and the NIHSS score decreased in each group. There were significant differences in the NIHSS, MBI, and GCS scores between the two groups ( t = 7.61, 6.26, 13.07, all P < 0.001). During the surgery and 6 months after surgery, the incidences of cerebral infarction, delayed cerebral hematoma, and acute encephalocele were significantly lower in the gradual decompression group than in the control group ( χ2 = 4.23, 4.35, 4.83, all P < 0.05). The Generic Quality of Life Inventory-74 Questionnaire scores in environment, psychological health, social relationship, and psychological health domains were significantly higher in the gradual decompression group than in the control group ( t = 8.16, 9.80, 8.68, 7.76, all P < 0.001) Conclusion:This study is the first to analyze the feasibility of gradual decompression for the treatment of severe traumatic brain injury in terms of intracranial pressure, quality of life, and short- and medium-term complications. Findings from this study confirm that gradual decompression can effectively lower intracranial pressure of patients with severe traumatic brain injury, improve neurological function, reduce complications, and improve patients' self-care ability and quality of life.

The experimental group and control group were assigned into a 1∶1 ratio by random table method. Inclusion criteria included age≥18 years and have indications for cystoscopy or removal of double J stent. Exclusion criteria included patients having acute genitourinary tract infection, having tuberculous bladder contracture, bladder capacity less than 50ml, having urethrostenosis, female menstrual period, pregnancy and lactation, having difficulty for lithotomy position, having serious cardio-cerebrovascular disease and liver or kidney dysfunction. A domestic disposable digital flexible cystoscope was adopted in the experimental group, whereas a reusable Olympus digital flexible cystoscope was used in the control group. Acceptability of image was defined as primary availability indicator, while success rate of working and performance score were defined as secondary availability indicators and mean operating time was calculated for cystoscopy only and cystoscopy plus removal of double J stent respectively, yet rate of adverse event as well as rate of equipment defects were sorted as safety indicators.Results:A total of 188 cases which were listed in per protocol set completed the clinical trial study successfully. There were 95 cases in the experimental group and 93 cases in the control group. Acceptability of image was 93.68%(89/95) and 96.77%(90/93) respectively in two groups( P=0.52). Success rate of working was 100.00%(95/95) and 98.92%(92/93) respectively in two groups ( P=0.49). Performance score was 14.41±0.93 and 14.56±0.84 respectively in two groups ( P=0.23). Mean operating time (MOT) only for cystoscopy was (15.3±2.6) min and (15.4±3.3)min respectively in two groups ( P=0.93), while MOT for cystoscopy plus removal of double J stent was (21.0±3.2) min and (21.7±3.9) min respectively in two groups ( P=0.69). Rate of adverse event was 8.42%(8/95) and 9.68%(9/93) respectively in two groups( P=0.76). There was no equipment defects in both groups. Conclusions:There is no statistical difference in acceptability of image, success rate of working, performance score, mean operating time for cystoscopy or removal of double J stent, rate of adverse events and rate of equipment defects. A domestic disposable digital flexible cystoscope has shown non-inferiority in the availability and safety compared with a reusable Olympus digital flexible cystoscope.

Thoracic drainage with traditional chest tube versus central venous catheter after video-assisted thoracoscopic lobectomy: A randomized controlled study / 中国胸心血管外科临床杂志

@#Objective    To evaluate the effectiveness and safety of a central venous catheter for thoracic drainage after video-assisted thoracoscopic lobectomy compared with a conventional chest tube. Methods    This study collected 200 patients with lung cancer who underwent thoracoscopic lobectomy and systematic hilar and mediastinal lymph node dissection between January 2018 and September 2019 in our hospital. The patients were randomly divided into two groups, including a group A (left with 28F chest tubes postoperatively) and a group B (left with 12G central venous catheters postoperatively). Patients in both groups were left with 2 chest tubes after upper lobectomy and 1 chest tube after middle or lower lobectomy. Duration and total volume of drainage, length of hospital stay, maximum visual analogue scale score and so forth were compared between the two groups. Results    Finally, 151 patients were included for analysis. There were 73 patients in the group A, including 26 males and 47 females, with an average age of 55.38±9.95 years, and 78 patients in the group B, including 37 males and 41 females, with an average age of 59.86±10.18 years. No statistical  difference was found between the two groups in drainage volume on postoperative day 2, and proportion of prolonged air leaks, hemothorax, chylothorax or drain reinsertion (all P>0.05). There was a statistical difference in drainage volume on postoperative day 1 [200.0 (120.0, 280.0) mL vs. 57.5 (10.0, 157.5) mL, P=0.000], postoperative day 3 [155.0 (100.0, 210.0) mL vs. 150.0 (80.0, 215.0) mL, P=0.023], total volume of drainage [890.0 (597.5, 1 530.0) mL vs. 512.5 (302.5, 786.3) mL, P=0.000], maximum pain score (2.29±0.72 points vs. 2.09±0.51 points, P=0.013) and length of hospital stay [7 (7, 9) d vs. 5 (4, 7) d, P=0.000]. Conclusion    Compared with conventional chest tubes, central venous catheters for chest drainage in patients with lung cancer after thoracoscopic lobectomy shortens the length of hospital stay and reduces postoperative pain.

Objective:To compare the performance and surgical outcomes of domestic single-use digital flexible ureteroscopes with reusable digital flexible ureteroscopes in treatment of upper urinary stones.Methods:A prospective, single-blind, multicenter and randomized controlled study was performed from September 2018 to June 2019. Eligible patients were randomly assigned, in a ratio of 1∶1, to either experimental group or control group. The inclusion criteria for the study were: aged 18-75 years, solitary upper urinary stone with stone size between 0.8 and 2.0 cm and CT value less than 1 400 HU, negative preoperative urine culture and normal renal function. Exclusion criteria included: patients with acute urinary tract infection, intransitable urethral strictures, impassable ureteropelvic junction obstructions, systemic hemorrhagic disease, coagulation function abnormalities or bleeding tendency, severe hypertension or cardiopulmonary insufficiency, severe hip malformation and difficulty in meeting the demand of operation position and pregnant and lactation women. The device used in the experimental group was a domestic single-use digital flexible ureteroscope, and the device used in the control group was an imported Olympus digital flexible ureteroscope. The qualified rate of clinical comprehensive evaluation (including image quality and operational performance), the rate of device failure, the stone-free rate and the occurrence rate of adverse events (including increase in urine red blood cell and white blood cell counts, postoperative hematuria, nausea, vomiting, dizziness, and fever) in the two groups were recorded.Results:A total of 186 eligible study cases were collected from the People's Hospital of Wuhan University, the First Affiliated Hospital of Xiamen University, and the First Affiliated Hospital of Guangzhou Medical University. 90 cases in the final experimental group and 88 cases in the control group completed the trial and were included in the evaluation. There were no statistically significant differences among age [(48.40±11.36) vs. (47.40±12.53)years old, P=0.594], male to female ratio (62/28 vs. 56/32, P =0.874), BMI [(24.8±2.1) kg/m 2 vs. (25.1±2.0)kg/m 2,P =0.331], hydronephrosis (no/slight vs. mild/severe) (62/28 vs. 65/23, P =0.874), stone location and stone size [(12.8±4.7) mm vs. (11.9±5.2) mm, P =0.227]. There were no significant differences in terms of qualified rate of clinical comprehensive evaluation [98.9% (89/90) vs. 100.0% (88/88), P =0.991], lithotripsy success rate [84.4% (76/90) vs. 84.1% (74/88), P =0.888], device failure/defect rate (both 0%), and the incidence of adverse events [50.0% (45/90) vs. 52.0% (51/88), P =0.894]. The highest incidence of adverse events in two groups was the increase of red blood cells and white blood cells of routine urine after operation. There was no serious adverse event in the experimental group and 1 serious adverse event in the control group. Conclusions:There was no significant difference in image quality, device failure/defect rate, lithotripsy success rate, and adverse event rate between single-use digital flexible ureteroscopes and reusable digital flexible ureteroscopes for lithotripsy of upper ureteral and pelvic stones. Domestic single-use digital flexible ureteroscopes have good safety and effectiveness in the treatment and microscopy of upper urinary tract stones.

Effect of early rehabilitation exercise on blood pressure of elderly patients with septic shock: a single-center, prospective, randomized controlled study / 中华危重病急救医学

Objective:To observe the effect of early rehabilitation exercise on blood pressure of elderly patients with septic shock.Methods:A single-center, prospective, randomized controlled study was conducted in elderly patients with septic shock who were hospitalized in the department of critical care medicine of Huangshan Shoukang Hospital (High-tech Zone Central Hospital of Huangshan) from December 2018 to November 2020. According to the principle of simple random, all patients were divided into control group and intervention group. Both groups were treated with lower limb barometry to prevent deep vein thrombosis, 3 times a day, 30 minutes each time. After comprehensive treatment in the intensive care unit (ICU), the severity of patients was gradually improved, the hemodynamics was relatively stable, and the norepinephrine was reduced to 0.5 μg·kg -1·min -1. The control group continued to receive lower limb barometric treatment without rehabilitation training, while the intervention group began rehabilitation training when the dose of norepinephrine was reduced to 0.5 μg·kg -1·min -1. The duration of norepinephrine use, the length of ICU stay, and the occurrence of adverse events during rehabilitation training in intervention group was recorded. Results:Seventy-two patients were included in the final analysis, 35 in intervention group and 37 in control group. There was no significant difference in gender, age, Oxford acute severity of illness score (OASIS), acute physiology and chronic health evaluationⅡ (APACHEⅡ), mean arterial pressure (MAP) of 3 times and underlying diseases between two groups. Compared with control group, the length of ICU stay and duration of dose of norepinephrine ≤0.5 μg·kg -1·min -1 in intervention group were significantly shorter [length of ICU stay (hours): 193.0 (145.5, 312.0) vs. 242.5 (180.0, 483.5), P < 0.05; duration of dose of norepinephrine ≤0.5 μg·kg -1·min -1 (hours): 120.0 (72.0, 144.0) vs. 144.5 (120.0, 192.0), Z = 2.976, P = 0.003]. In intervention group, 35 patients did not show acute myocardial infarction, arrhythmia, syncope, central venous catheter detachment, and gastric tube detachment during the rehabilitation period, except 1 patient suffered from naked hematuria due to urinary catheter traction, which disappeared the next day after symptomatic treatment. Conclusion:The early rehabilitation exercise was beneficial to the recovery of autonomic blood pressure in elderly patients with septic shock, shorten the time of norepinephrine use and ICU stay.

Meta-analysis of inhaled nitric oxide in gestational age ≤34 weeks preterm infants / 中国新生儿科杂志

Objective:To evaluate the effect of inhaled nitric oxide (NO) in gestational age ≤34 weeks preterm infants using meta-analysis.Method:A search from PubMed, Embase, Cochrane Central library, China National Knowledge Internet, China biomedical literature database, Wanfang and VIP database from establishment to June 2020.Result:A total of 17 randomized controlled studies were included. The subjects were premature infants (gestational age ≤34 weeks) who needed respiratory support. The total sample size was 4 033.Meta-analysis showed that no significant difference was found in mortality between treatment and control groups ( RR=1.00, 95% CI 0.89~1.11, P=0.930).Risk of bronchopulmonary dysplasia (BPD) at 36 w postmenstrual age (PMA) was significantly lower in preterm infants supplemented with iNO ( RR=0.89, 95% CI 0.82~0.97, P=0.006). Subgroup analysis showed the overall risk of mortality or BPD incidence was significantly reduced for birth weight >1 000 g infants treated with iNO ( RR=0.72, 95% CI 0.58~0.89, P=0.002). Risk of BPD incidence was significantly lower when beginning iNO in the first 7 d of life ( RR=0.83, 95% CI 0.70~0.98, P=0.030). Risk of BPD incidence was significant reduced in infants treated with 5 ppm or ≥10 ppm iNO ( RR=0.89, 95% CI 0.81~0.98, P=0.020; RR=0.90, 95% CI 0.81~0.99, P=0.030). There was a decrease in BPD incidence with iNO treatment time of either ≤7 d or >7 d ( RR=0.77, 95% CI 0.60～0.99, P=0.040; RR=0.87, 95% CI 0.77~0.97, P=0.010). There were no differences concerning mechanical ventilation duration and intracranial hemorrhage incidence ( P>0.05). Significant difference was found between treatment and control group with respect to reduction of oxygenation index (OI) ( WMD=-6.32, 95% CI -12.16~-0.48, P=0.030). Conclusion:For preterm infants born at less than 34 weeks who need respiratory support, iNO treatment may improve oxygenation and reduce the risk of BPD, but not decrease mortality, mechanical ventilation duration or intracranial hemorrhage incidence. A better treatment effect may be achieved if iNO treatment began in the first 7 d of life, and if the infant had a birth weight greater than 1 000 g.

Effect of driving pressure-guided lung protective ventilation strategy on early postoperative pulmonary function in adults patients undergoing heart valve surgery: A randomized controlled study / 中国胸心血管外科临床杂志

@#Objective    To evaluate the effect of driving pressure-guided lung protective ventilation strategy on lung function in adult patients under elective cardiac surgery with cardiopulmonary bypass. Methods    In this randomized controlled trial, 106 patients scheduled for elective valve surgery via median sternal incision under cardiopulmonary bypass from July to October 2020 at West China Hospital of Sichuan University were included in final analysis. Patients were divided into two groups randomly. Both groups received volume-controlled ventilation. A protective ventilation group (a control group, n=53) underwent traditional lung protective ventilation strategy with positive end-expiratory pressure (PEEP) of 5 cm H2O and received conventional protective ventilation with tidal volume of 7 mL/kg of predicted body weight and PEEP of 5 cm H2O, and recruitment maneuver. An individualized PEEP group (a driving pressure group, n=53) received the same tidal volume and recruitment, but with individualized PEEP which produced the lowest driving pressure. The primary outcome was oxygen index (OI) after ICU admission in 30 minutes, and the secondary outcomes were the incidence of OI below 300 mm Hg, the severity of OI descending scale (the Berlin definition), the incidence of pulmonary complications at 7 days after surgery and surgeons’ satisfaction on ventilation. Results    There was a statistical difference in OI after ICU admission in 30 minutes between the two groups (273.5±75.5 mm Hg vs. 358.0±65.3 mm Hg, P=0.00). The driving pressure group had lower incidence of postoperative OI<300 mm Hg (16.9% vs. 49.0%, OR=0.21, 95%CI 0.08-0.52, P=0.00) and less severity of OI classification than the control group (P=0.00). The incidence of pulmonary complications at 7 days after surgery was comparable between the driving pressure group and the control group (28.3% vs. 33.9%, OR=0.76, 95%CI 0.33-1.75, P=0.48). The atelectasis rate was lower in the driving pressure group (1.0% vs. 15.0%, OR=0.10, 95%CI 0.01-0.89, P=0.01). Conclusion    Application of driving pressure-guided ventilation is associated with a higher OI and less lung injury after ICU admission compared with the conventional protective ventilation in patients having valve surgery.

A self-controlled study on corneal nerve invasion phenomenon of Bowman's membrane in patients with ⅢA lattice corneal dystrophy / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To analyze and study the corneal nerve invasion phenomenon of Bowman's membrane in patients with IIIA lattice corneal dystrophy by confocal laser scanning microscopy. Quantitative analysis of 10a continuous observation image data was performed, followed by self-control studies.<p>METHODS: A total of 10 patients(13 eyes)with IIIA Lattice corneal dystrophy were continuously examined by confocal laser scanning microscopy. The data were observed and analyzed. <p>RESULTS: The normal corneal nerve of Bowman's membrane(Grade 0)of IIIA LCD patients gradually decreased with the prolongation of observation time. The nerves of grade I to V involved(amyloid-wrapped nerve fibers)gradually increased correspondingly. So suggested that the corneal nerve invasion of Bowman's membrane(amyloid deposits)in patients with IIIA LCD were gradually increasing with time. <p>CONCLUSION: In patients with type ⅢA lattice corneal dystrophy, there is a neurotropic phenomenon in Bowman's membrane, which gradually worsens with the aggravation of the lesion. This lesion can explain the recurrent epithelial damage of the IIIA LCD from some degrees. Continuous observation of patients with type IIIA LCD by corneal laser confocal microscopy can well understand the development of the lesion and explain its clinical manifestations.

Objective@#To evaluate the 1-year clinical outcome of orthokeratology contact lens wear and glasses wear for myopia in children, mainly focusing on the effects on the biological parameters of the eyeballs.@*Methods@#A randomized-controlled clinical study analyzed 200 eyes of 200 adolescent, with low and moderate myopia from January 2018 to August 2018 at Chengdu Aier Eye Hospital.The subjects were divided into an orthokeratology group and a spectacles group, 100 eyes in each group.The axial lengths (AL), central corneal thickness (CCT), anterior chamber depth (ACD), and crystalline lens thickness were measured and compared between the two groups before and 6 months, 12 months after wearing the lenses, and 1 month after stopping lens wear.This study conformed to the tenets of the Declaration of Helsinki.Written informed consent was obtained from each subject prior to entering the study cohort.The study protocol was approved by the Ethics Committee of Chengdu Aier Eye Hospital (No.[2018]01-1).@*Results@#The overall difference in AL was statistically significant in the two groups at various time points(Fgroup= 4.617, P=0.043; Ftime=10.939, P=0.023). Compared with before wearing lenses, the AL was significantly lengthened in both of the groups at 6 and 12 months after wearing lenses and 1 month after stopping lens wear (all at P<0.05). There was no significant difference in AL between 1 month after stopping lens wear and 12 months after wearing lenses in the orthokeratology group (P>0.05). Twelve months after wearing lenses, the AL increases values of the orthokeratology group were significantly lower than those of the spectacles group ([0.13±0.06]mm vs. [0.29±0.08]mm) (t=16.000, P=0.002). The differences in CCT at time points in the two groups were statistically significant (Fgroup=2.297, P=0.013; Ftime=11.219, P<0.01). At 6 and 12 months after wearing the lenses, the CCT in the orthokeratology group was significantly thinner than that before lens wear (all at P<0.05). CCT showed no significant difference between 1 month after stopping lens wear and before wearing lenses in the orthokeratology group (P>0.05). There was no statistically significanant difference in the ACD between the two groups at time points (Fgroup=4.226, P=0.051; Ftime=3.208, P=0.057). The overall differences in crystalline lens thickness at time points before and after wearing lenses in the two groups were statistically significant (Fgroup=13.13, P<0.01; Ftime=0.804, P=0.047). At 6 and 12 months after wearing the lenses and 1 month after stopping lens wear, the crystalline lens thickness in the orthokeratology group was significantly greater than that before lens wear and that in the spectacles group at the same time points (all at P<0.05). There was no significant difference in the crystalline lens thickness between 1 month after stopping lens wear and 12 months after wearing the lenses in the orthokeratology group (P>0.05).@*Conclusions@#Compared with wearing spectacles, orthokeratology lenses wear can effectively slow down the prolongation of the AL, decrease CCT reversibly and increase crystalline lens thickness in adolescent myopic subjects, but it has no significant effect on the ACD.

A randomized-controlled clinical study of one-year outcome between orthokeratology contact lens wear and glasses wear in myopic children / 中华实验眼科杂志

Objective To evaluate the 1-year clinical outcome of orthokeratology contact lens wear and glasses wear for myopia in children,mainly focusing on the effects on the biological parameters of the eyeballs.Methods A randomized-controlled clinical study analyzed 200 eyes of 200 adolescent,with low and moderate myopia from January 2018 to August 2018 at Chengdu Aier Eye Hospital.The subjects were divided into an orthokeratology group and a spectacles group,100 eyes in each group.The axial lengths (AL),central corneal thickness (CCT),anterior chamber depth (ACD),and crystalline lens thickness were measured and compared between the two groups before and 6 months,12 months after wearing the lenses,and 1 month after stopping lens wear.This study conformed to the tenets of the Declaration of Helsinki.Written informed consent was obtained from each subject prior to entering the study cohort.The study protocol was approved by the Ethics Committee of Chengdu Aier Eye Hospital (No.[2018]01-1).Results The overall difference in AL was statistically significant in the two groups at various time points (Fgroup =4.617,P =0.043;Ftime =10.939,P =0.023).Compared with before wearing lenses,the AL was significantly lengthened in both of the groups at 6 and 12 months after wearing lenses and 1 month after stopping lens wear (all at P＜ 0.05).There was no significant difference in AL between 1 month after stopping lens wear and 12 months after wearing lenses in the orthokeratology group (P＞0.05).Twelve months after wearing lenses,the AL increases values of the orthokeratology group were significantly lower than those of the spectacles group ([0.13±0.06]mm vs.[0.29±0.08] mm) (t=16.000,P=0.002).The differences in CCT at time points in the two groups were statistically significant (Fgroup =2.297,P =0.013;Ftime =11.219,P＜ 0.01).At 6 and 12 months after wearing the lenses,the CCT in the orthokeratology group was significantly thinner than that before lens wear (all at P＜ 0.05).CCT showed no significant difference between 1 month after stopping lens wear and before wearing lenses in the orthokeratology group (P＞0.05).There was no statistically significanant difference in the ACD between the two groups at time points (Fgroup =4.226,P =0.051;Ftime =3.208,P=0.057).The overall differences in crystalline lens thickness at time points before and after wearing lenses in the two groups were statistically significant (Fgroup =13.13,P＜0.01;Ftime =0.804,P =0.047).At 6 and 12 months after wearing the lenses and 1 month after stopping lens wear,the crystalline lens thickness in the orthokeratology group was significantly greater than that before lens wear and that in the spectacles group at the same time points (all at P＜0.05).There was no significant difference in the crystalline lens thickness between 1 month after stopping lens wear and 12 months after wearing the lenses in the orthokeratology group (P＞0.05).Conclusions Compared with wearing spectacles,orthokeratology lenses wear can effectively slow down the prolongation of the AL,decrease CCT reversibly and increase crystalline lens thickness in adolescent myopic subjects,but it has no significant effect on the ACD.

Efficacy of levetiracetam as the first line anti- epileptic drug in management of neonatal seizures

Background: Neonatal seizure management has not changed much in the last 50 years. Neuronal apoptosis in animal models and cognitive impairment in human subjects has been reported with the use of Phenobarbitone. Levetiracetam is advantageous as it is effective, well tolerated and has least drug interactions.Methods: This double blinded, randomized, parallel group, active controlled study was conducted among 66 neonates in the Neonatal intensive care unit of a tertiary care hospital for a period of 18 months. Neonates with seizures fulfilling the inclusion criteria were treated either with Phenobarbitone or Levetiracetam. Seizure control was defined as no seizure activity within 40 minutes of the administration of the first drug. Failure of first line agent was treated with Phenytoin. Neonates were observed for a period of 14 weeks for recurrence of seizure and any serious adverse effects.Results: Effective seizure control was achieved in 64.7% neonates in Levetiracetam group as compared to 31.2% in Phenobarbitone group (p <0.05). Early resumption of breast feeds within 6 hours of therapy was achieved in 73.5% neonates treated with Levetiracetam compared to 31.2% neonates treated with Phenobarbitone (p value = 0.001).Conclusions: Levetiracetam is a promising alternative as first line Anti-epileptic drug in neonates with seizures. Prolonged sedation was the adverse effect noted to Phenobarbitone that made breast feeding and neuro- assessment difficult. No serious adverse effects were seen with Levetiracetam.

The study on the effect of ginkgo biloba extracts on MnSOD activity in the treatment of tardive dyskinesia / 中国神经精神疾病杂志

To investigate if ginkgo biloba extract (Egb-761) can improve tardive dyskinesia (TD) symptoms through increasing the activity of plasma MnSOD. Methods We enrolled a total of 384 schizophrenia patients including 157 TD patients and 227 non-TD patients, as well as 280 normal subjects. The difference of MnSOD level in plasma among these groups were compared. TD patients were then randomly divided into two groups. The treatment group (n=77) and the placebo group (n=75) were treated with 240 mg of Egb-761 or placebo per day for 12 weeks, respectively. The abnormal involuntary movement scale (AIMS) and the positive and negative symptoms scale (PANSS) were used to evaluate the severity of the symptoms in baseline, the sixth week and the twelfth week after treatment. The level of MnSOD activity in plasma was also detected before and after the treatment. Results The level of MnSOD activity was lower in schizophrenia groups than in healthy control group (P＜0.01). In addition, the level of MnSOD activity was significantly lower in TD group than in non-TD group (P＜0.05). Repeated measures analysis of variance showed that group effect (F=4.00, P=0.05), time effect (F=32.17, P＜0.01) and interactive effect of group and time (F=39.04, P＜0.01) were significant in AIMS total score. The AIMS total score of treatment group was significantly lower than that of placebo group at 6-week and 12-week time points (all P＜0.01). Repeated measures analysis of variance showed that time effect (F=23.04, P＜0.01) and interactive effect of group and time (F=6.41, P＜0.05) were significant in the level of MnSOD activity. In addition, the level of MnSOD at baseline was significantly correlated with the reduction of AIMS total score during the treatment period (r=0.27, P=0.018). Conclusion Treatment of Egb-761 can improve symptoms of TD and activity of MnSOD.

Effects of Balint group intervention on occupational burnout of primary care physicians / 中华行为医学与脑科学杂志

Objective To examine the effects of participating in Balint group ( PBG) for reducing occupational burnout among primary care physicians (PCPs). Methods In this randomized controlled trial, 240 PCPs were randomly assigned to PBG (n=70) and control group (n=240) in propotion of 1 ∶ 2. Sub-jects of PBG received Balint group intervention for one year,while control group received natural observation. Maslach Burnout Inventory ( MBI) was used to assess the severity of occupational burnout. Results At baseline all three subscales of MBI had no significant difference between PBG and cotrol group(P>0. 05). After the intervention,PBG had statistically lower subscale scores in emotional exhaustion ((20. 1±8. 3) vs (22. 6±8. 7),t=1. 993,P=0. 048) and depersonalization (( 6. 8± 4. 9) vs ( 10. 8 ± 5. 2),t=5. 355,P<0. 001) than the control group, while had statistically higher score in personal accomplishment subscale ((38. 3±7. 5) vs (34. 6±7. 7),t=3. 311,P=0. 001) than the control group. Conclusions PBG is effective in reducing occupational burnout among PCPs.

Dual therapy with lopinavir/ritonavir plus lamivudine could be a viable alternative for antiretroviral-therapy-naive adults with HIV-1 infection regardless of HIV viral load or subgenotype in resource-limited settings: A randomised, open-label and non-inferiority study from China

Backgrounds: This randomised controlled, open-label, non-inferiority trial was conducted in antiretroviral-na飗e HIV-1-infected patients to assess the efficacy and safety of 48-week dual therapy of LPV/r plus 3TC (DT group) compared with Chinese first-line triple-therapy regimen (TT group). Methods: 198 were randomised to DT (n = 100) or TT (n = 98). Results: Ninety-two DT patients (92%) and 88 TT patients (89.8%) achieved HIV-1 RNA <50 copies/ml at week 48 (P = 0.629). Moreover, the safety profile was similar between two groups, and no secondary HIV resistance was observed. Conclusion: The results suggest that dual therapy of LPV/r plus 3TC is non-inferior to the first-line triple-therapy regimen in China.

Efficacy and safety of surgery combined with intraperitoneal chemotherapy for advanced gastric cancer:a Meta-analysis / 肿瘤研究与临床

Objective To evaluate the efficacy and safety of surgery combined with intraperitoneal chemotherapy for advanced gastric cancer (AGC). Methods The related randomized controlled trials were searched in the following databases such as Cochrane Library, PubMed, Web of Science from database establishment to April 2017. Data extraction and quality assessment by means of NOS were completed by two researchers.The survival rate,recurrence rate,mortality and morbidity were analyzed by RevMan 5.3 software. Results Seventeen literatures which were strictly filtrated from the original 2 383 literatures were included for Meta-analysis and the NOS score was 6-8. A total of 2 302 AGC cases were included to divide for 1 175 undergoing surgery with intraperitoneal chemotherapy and 1 127 undergoing surgery alone. Meta-analysis results showed that compared with surgery alone, surgery with intraperitoneal chemotherapy could improve the 1-year(OR=1.93,95 % CI 1.41-2.66,P<0.000 1),2-year(OR=1.82,95 % CI 1.41-2.35,P<0.000 01) and 3-year (OR= 1.93, 95 % CI 1.54 - 2.42, P< 0.000 01) survival rate of ACG cases, while the overall mortality was reduced (OR=0.47, 95 % CI 0.34-0.64, P<0.000 01). In terms of recurrence rate, the overall(OR=0.46,95 % CI 0.32-0.68,P<0.000 1)and peritoneal(OR=0.47,95 % CI 0.29-0.76,P=0.002) recurrence rates of surgery with intraperitoneal chemotherapy were both lower than those of surgery alone. There were not significantly differences between surgery with intraperitoneal chemotherapy and surgery alone in lymph nodes and liver metastasis rate. However, surgery with intraperitoneal chemotherapy had more high occurrence rates than surgery alone (OR= 1.47, 95 % CI 1.16 - 1.85, P= 0.001), especially the bone suppression (OR= 3.07, 95 % CI 1.70 - 5.54, P= 0.002) and bleeding (OR= 3.00, 95 % CI 1.09- 8.27, P= 0.03), and there were no differences in other complications. Subgroup results indicated that the overall mortalities were obviously decreased in surgery with intraperitoneal chemotherapy + MMC (OR= 0.35, 95 % CI 0.20-0.62,P=0.000 3)or CDDP+5-Fu(OR=0.32,95 % CI 0.17-0.61,P=0.000 5)compared with surgery alone. Conclusions Surgery with intraperitoneal chemotherapy can improve survival rate of AGC cases over a period of time and reduce mortality and peritoneal recurrence, but it is likely to cause the morbidities.The safety needs to be improved in the future.
