Abstract Prevention and control of myopia requires comprehensive measures. Based on the system established earlier, the system is revised and upgraded. The original system emphasizes comprehensive measures and proposes to focus on both the symptoms and root causes. These measures are summarized into six aspects, three address the root cause measures including health education, glasses optics and visual environment, and three address symptoms measures including eye exercises, physical therapy and drugs. The paper is comprehensively supplemented and analyzes the primary and the secondary, and promotes physical therapy from treating the symptoms to treat both the symptoms and the root causes. These improvement measures will help promote the prevention and control of myopia in children and adolescents.

Objective:To investigate the specific method, efficacy and safety of intrathecal baclofen (ITB) in the treatment of moderate and severe spasticity.Methods:The clinical features, response to ITB trial, clinical outcomes and treatment-related complications after baclofen pump implantation surgery were retrospectively analyzed in patients with moderate to severe spasticity who received ITB treatment in Hong Kong University Shenzhen Hospital from August 2022 to August 2023.Results:The study included 22 patients with moderate to severe spasticity, of whom 18 patients (81.8%) were effective in ITB trial. For these patients with effective trial, the lowest mean Modified Ashworth Scale (MAS) score of lower extremity muscle groups after ITB bolus injection was decreased significantly compared with the baseline mean value before injection (1.29±0.81 vs 3.31±1.18 , t=11.364, P<0.001), and the M/H amplitude ratio of soleus H-reflex at 4 hours after ITB bolus injection was significantly higher than the baseline value (9.61±4.66 vs 3.83±2.69, t=7.780, P<0.001). Among the 18 patients with effective ITB trial, 10 patients received baclofen pump implantation surgery with the informed consent of the patients or their guardians. Compared with the 8 patients without surgery, the baseline mean MAS score of lower extremity muscle groups of the 10 patients who received surgery was higher (3.71±1.06 vs 2.83±1.16, F=5.645, P<0.05), the maximum reduction of mean MAS score of lower extremity muscle groups of the 10 patients who received surgery was greater (2.61±0.99 vs 1.30±0.64, F=20.696, P<0.001). In 10 patients who received baclofen pump implantation surgery, the mean MAS score of lower limb muscle groups was significantly decreased in the first and sixth months after surgery compared with the baseline mean value before surgery (1.64±0.91, 1.16±0.89 and 3.71±1.06, F=39.946, P<0.001). Among them, 2 patients were followed up to 12 months after surgery, 2 patients were followed up to 18 months after surgery, and the mean MAS score of their lower limb muscle groups showed continuous improvement, and 1 patient with cerebral palsy combined with lower urinary tract hyperactive syndrome also showed significant improvement of urgent urinary incontinence after surgery. Up to the last follow-up, the daily dose of baclofen in 10 patients receiving baclofen pump implantation was (143.60±96.24) μg, and no treatment-related complications occurred. Conclusions:ITB can effectively relieve spasticity symptoms and other related neurological dysfunction in patients with moderate and severe spasticity, and the efficacy can be maintained for a long time, and treatment-related complications are rare. Preoperative ITB trial is helpful to screen out patients more suitable for baclofen pump implantation. Patients with higher grade of spasticity at baseline and better efficacy of ITB trial are more suitable for baclofen pump implantation. The soleus H reflex can effectively reflect the change of stretch reflex of lower limb muscle groups in patients with spasticity treated by ITB, and can be used to evaluate the treatment effect of ITB.

BackgroundThe incidence of delirium in critically ill psychiatric patients is high， and there are many factors affecting delirium occurrence. At present， epidemiological studies on delirium among critically ill patients in psychiatric hospitals are limited. ObjectiveTo explore the risk factors for delirium in critically ill patients in a psychiatric hospital， so as to guide the clinical management of delirium in psychiatric hospitals. MethodsThis retrospective study included 427 critically ill patients who were admitted to Shenzhen Kangning Hospital from January 1， 2019 to May 31， 2021. The delirium situation， gender， age， pre-admission course of illness （duration from the onset of acute mental state changes to in-patient registration at a psychiatric hospital）， history of mental illness， history of cognitive dysfunction， history of using psychoactive substances， history of using sedative and hypnotic drugs， number of combined chronic diseases， number of combined drugs and type of disease were examined as potential risk factors for delirium. Single Logistic regression was used to analyze the potential risk factors for delirium， and the potential risk factors were incorporated into the multi-factor Logistic regression analysis model so as to gradually screen out the risk factors for delirium in critically ill psychiatric patients. ResultsDelirium was present in 33.49% （143/427） of critically ill patients. Multi-factor Logistic regression analysis demonstrated that the presence of delirium was associated with mental and behavioral disorders caused by psychoactive substances （OR=8.949， P<0.01）， absent history of mental illness （OR=4.202， P<0.01）， number of combined chronic diseases （OR=1.249， P<0.01）， age （OR=1.031， P<0.01） and pre-admission course of illness （OR=0.942， P<0.01） . ConclusionDelirium was present in nearly 1/3 critically ill patients in the psychiatric hospital. The risk factors for delirium included short course of illness before admission， age， more combined chronic diseases， absent history of mental illness， mental and behavioral disorders caused by psychoactive substances. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）］

OBJECTIVE To establish the fingerprints of Kangfuyan capsules and carry out chemical pattern recognition analysis，and simultaneously determine the contents of five components so as to promote the quality standard of the drug. METHODS High performance liquid chromatography （HPLC）fingerprints of 11 batches of Kangfuyan capsules （S1-S11）were established by Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）；identification and attribution analysis of chromatographic peaks were carried out by comparison with the chromatograms of the reference substance and the decoction pieces of single ingredient. SPSS 26.0 and SIMCA 14.1 software were used for cluster analysis and principal component analysis. HPLC method was used to determine the contents of matrine ，phellodendrine chloride ，rutin，forsythoside A and berberine hydrochloride. RESULTS There were 29 common peaks in the fingerprints for 11 batches of samples ，and the similarity was higher than 0.99. A total of 5 chromatographic peaks were identified ，which are matrine （peak 3），phellodendron chloride （peak 14），rutin （peak 20），forsythiaside A （peak 22） and berberine hydrochloride （peak 28）. The results of cluster analysis and principal component analysis showed that S 1-S9 were clustered into one category ，and S 10 and S 11 were clustered into another category. The contents of above 5 components were 29.320 5-60.144 3，0.621 6-1.076 6，1.025 9-2.830 5，2.899 3-6.212 7 and 4.425 1-8.581 6 mg/g， respectively. CONCLUSIONS The established fingerprint and content determination method are stable and reliable ，and can provide reference for the quality control of the preparation in combination with chemical pattern recognition analysis.

In this study, molecular imprinted polymer (MIP) was prepared by sol-gel process to obtain paeoniflorin and its derivatives in GZFLC. The static adsorption capacity of MIP was measured by scatchard equation. The results showed that the maximum apparent absorbing capacity of MIP was 52.28 mg·g-1. One-step separation of paeoniflorin from 4 g methanol samples of GZFLC was 197 mg with the purity of 89.3%. It was concluded that paeoniflorin MIP can be used to separate phaoniforin and its analogues from GZFLC.

Objective To investigate the causes and treatments of severe complications after laparoscopic surgery. Methods Clinical data of 7 cases with severe complications after laparoscopic surgery in the Third People’s Hospital of Shenzhen from January 2008 to January 2013 were analyzed retrospectively. The informed consents of all patients were obtained and local ethical committee approval had been received. There were 3 males and 4 females with the age ranging from 6 to 67 years old and median of 40 years old. The diagnosis, treatments clinical data of the patients were collected, and the causes, treatments and prevention measures of the complications were summarized. Results Five cases underwent laparoscopic cholesystectomy (LC), 4 of which suffered bile duct injury for severe abdominal adhesion and unclear anatomy of the Calot triangle and 1 case suffered strangulated intestinal obstruction after operation because the hepatic falciform ligament was ruptured when puncturing below the xiphoid. One case underwent laparoscopic high ligation of hernial sac for indirect inguinal hernia and suffered strangulated intestinal obstruction after operation because part of the small intestine ran out of the peritoneum through the port site below the umbilicus. One case underwent laparoscopic tension-free repair for indirect inguinal hernia and suffered ischemic necrosis of the left testis possibly because of testicular torsion when stretching the tissue. The 4 cases with bile duct injury received primary drainage, 3 of which underwent secondary Roux-en-Y cholangiojejunostomy for severe biliary stricture and all recovered well after operation, and the other case underwent endoscopic biliary stent implantation 3 months after operation. The 2 cases with strangulated intestinal obstruction underwent emergent partial resection and end-to-end anastomosis of small intestine and recovered well after operation. The case with necrosis of testis underwent testicular excision. Conclusions The main causes of severe complications after laparoscopic surgery probably are the unclear local anatomy and failing to convert surgical procedure timely, etc. Early diagnosis, comprehensive evaluation and proper surgical interventions are the important measures for improving the prognosis of these patients.
