Central post-stroke pain (CPSP), a neuropathic pain syndrome occurring after a cerebrovascular accident, is characterized by pain or paraesthesia in the part of the body dominated by the area of the brain where blood vessels are injured. CPSP patients are often accompanied by anxiety, depression and other emotional disorders, which have a serious negative impact on patients' quality of life. However, the pathogenesis of CPSP has not been fully elucidated, the clinical diagnosis rate is not high, and the commonly used treatment methods are not effective. This article reviews the clinical features, epidemiology, pathogenesis and treatment of CPSP in order to provide reference for the elucidation of CPSP mechanism and effective treatment.

Objective:To evaluate the effect of esketamine combined with ultrasound-guided dorsal penile nerve block (DPNB) on negative postoperative behavioral changes (NPOBCs) in pediatric patients undergoing circumcision under general anesthesia.Methods:One-hundred and ninety-five pediatric patients, aged 4-8 yr, with body mass index of 10-35 kg, of American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱ, undergoing elective circumcision under general anesthesia, were selected and divided into 3 groups ( n=65 each) using a random number table method: esketamine group (group E), DPNB group (group D) and esketamine combined with DPNB group (group ED). Propofol 1.5 mg/kg was intravenously injected, and the patients were admitted to the operating room after consciousness disappeared in the 3 groups. Esketamine 0.5 mg/kg was intravenously injected in E and ED groups, and the equal volume of normal saline was given in group D. D and ED groups underwent bilateral DPNB with 0.25 % ropivacaine 0.15 ml/kg under ultrasound guidance, with the maximum total amount of the drug not exceeding 10 ml. Fentanyl 1.0 μg/kg and propofol 2.0 mg/kg were intravenously injected prior to the skin incision in the three groups. If intraoperative body movement occurred, propofol 10 mg was added, which could be repeated. The occurrence of intraoperative body movement, respiratory depression and amount of propofol added was recorded. When postoperative pain (FLACC score >4) occurred, flurbiprofen 1 mg/kg was intravenously injected for analgesia, and the usage of flurbiprofen was recorded. When emergence agitation(PEAD score>10) occurred, propofol 1 mg/kg was intravenously injected for sedation, and the occurrence of emergence agitation was recorded. Parents were followed up by telephone at 1, 7 and 30 days postoperatively to assess the occurrence of NPOBCs using the PHBQ scale. Results:Fifty-six patients in group E and 59 patients in D and ED groups finally completed the study.Compared with group E, the incidence of intraoperative body movement was significantly decreased, the amount of additional propofol was reduced, the emergence agitation score, incidence of emergence agitation and severe agitation and usage rate of postoperative flurbiprofen were decreased, and the incidence of separation anxiety at 7 and 30 days postoperatively was decreased in D and ED groups, and the incidence of intraoperative respiratory depression was significantly decreased, and the incidence of NPOBCs at 7 and 30 days postoperatively was decreased in group ED ( P<0.05). Compared with group D, the incidence of intraoperative respiratory depression was significantly decreased, the amount of additional propofol was decreased, the usage rate of postoperative flurbiprofen and incidence of sleep anxiety at 1 day postoperatively were decreased ( P<0.05), and no significant change was found in the incidence of NPOBCs at each time point after operation in group ED ( P>0.05). Conclusions:Esketamine combined with ultrasound-guided DPNB can reduce the occurrence of NPOBCs in pediatric patients undergoing circumcision under general anesthesia.

To investigate the clinical and endoscopic characteristics and endoscopic treatment efficacy of cap polyposis, data of 14 patients (56 polyps) who were histologically diagnosed as having cap polyposis after endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) in Beijing Friendship Hospital from June 2017 to February 2021 was retrospectively analyzed. Of the 14 patients, 8 were males and 6 were females. The age ranged from 14 to 74 years, including 7 cases of <60 years old and 7 cases of ≥60 years old. 7 patients (50.0%) had clinical manifestations. Four cases had multiple polyps and 10 cases (71.4%) had single polyps. There were 42 polyps (75.0%) located in the rectum, 13 (23.2%) in the sigmoid colon and 1 in the transverse colon. According to the classification of Yamada, 44 polyps (78.6%) were type Ⅰ, 3 polyps were type Ⅱ, 5 polyps were type Ⅲ and 4 polyps were type Ⅳ. Under endoscopy, there were 41 polyps (73.2%) with obvious white cap-like coverings on the surface and 23 polyps with obvious hyperemia and redness on the mucosa, 8 of which were both visible. Two cases were treated with ESD and 12 cases were treated with EMR, all of which were completely excised. No bleeding, perforation, infection or other complications occurred during and after operation. The clinical symptoms of 7 patients were relieved. During the follow-up period, 11 cases (78.6%) completed colonoscopy, and no polyp recurrence was found. In conclusion, there is no gender or age difference in patients of cap polyposis. It is usually single and located in the rectum and sigmoid colon with Yamada type Ⅰ. The surface of lesions is mostly covered with white cap. Patients may have no obvious clinical symptoms. Treatment of ESD and EMR is safe and effective for cap polyposis.

Kidney cancer usually requires multidisciplinary individualized treatments. No matter what kind of treatment, drugs are essential. According to the "six-step process" (prescription legitimacy review, patient basic information evaluation review, treatment protocol review, organ function and laboratory index review, pretreatment review, and unconventional prescription review) in prescription review proposed by the anti-tumor drug prescription review expert group and referring to domestic and foreign kidney cancer guidelines and drug instructions in recent years, this consensus selects 9 targeted drugs and 4 immunotherapeutic drugs that are currently commonly used in China and elaborates the key review points in patient basic information evaluation review, treatment protocol review, and organ function and laboratory index review of kidney cancer drug treatment, in order to provide reference for clinical front-line pharmacists to review prescriptions of kidney cancer patients and promote rational drug use in clinic.

Objective:To compare the therapeutic effect between regular spherical corneal refractive therapy (CRT) and dual axis CRT on myopia with corneal astigmatism.Methods:A non-randomized controlled study was conducted.Aged 8 to 14 years old, forty-eight patients (48 eyes) wearing CRT orthokeratology enrolled from May, 2018 to December, 2018 in First Affiliated Hospital of Army Medical University were divided into dual axis CRT group (24 eyes) and spherical CRT group (24 eyes) according to their guardians' willingness.After 1-year follow-up, the visual acuity, eccentricity distance in treatment area, annual axial growth and the corneal punctate staining incidence of the two groups were compared.The study followed the Declaration of Helsinki, and was approved by an Ethics Committee of First Affiliated Hospital of Army Medical University (No.KY201975). Written informed consent was obtained from guardians prior to any examination.Results:The uncorrected visual acuity of the dual axis CRT group was better than that of the spherical CRT group at one week and one month after correction, and the differences were statistically significant (both at P<0.05), and there was no significant difference in uncorrected visual acuity between the two groups at other time points (all at P>0.05). The deviations of optical center in the spherical CRT group at each observation time points were significantly larger than that in the dual axis group (all at P<0.05), and the deviation was not obviously changed with time in both groups and there was no significant difference in deviation change between the two groups ( Ftime=2.301, P=0.074). The eccentricity was mainly in horizontal direction in spherical CRT group.The median annual axial growth was 0.12 (0.10, 0.45)mm in the dual axis CRT group and 0.14 (0.10, 0.46)mm in the spherical CRT group, with no significant difference between the two groups ( Z=0.248, P=0.804). There was 4.2%(1/24) of the patients having grade Ⅲ-Ⅳ corneal punctate staining in the dual axis CRT group, and 25.0%(6/24) in the regular spherical CRT group, showing significant difference between the two groups ( χ2=4.180, P=0.049). Conclusions:For the treatment of myopia with astigmatism, dual axis CRT shows better centricity and safety than spherical CRT.

Objective: To analyze the change trend of HIV genetic subtypes and compare the first CD₄⁺T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control. Methods: Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD₄⁺T cell counts (CD₄) of the different subtype HIV infected patients. Results: A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD₄ of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD₄ levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001). Conclusion The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD₄ levels of the patients were low in Liuzhou during 1998 to 2012.

Objective To firstly report the clinical features,diagnosis and treatment response of patients with anti-γ-aminobutyric acid type A receptor (GABAAR) encephalitis in China,thus raising neurologists' awareness of this emerging type of autoimmune encephalitis.Methods Specific anti-GABAAR autoantibodies in the serum and cerebrospinal fluid (CSF) of patients with suspected autoimmune encephalitis but negative for commercial available antibody tests were detected by live cell-based assay (CBA).The clinical features,laboratory examinations and treatment of two cases of autoimmune encephalitis with anti-GABAAR autoantibodies were analyzed,who admitted to Huashan Hospital,Fudan University between 2013 and 2014.Results By using live CBA,serum and CSF of the two patients diagnosed with possible autoimmune encephalitis both contained autoantibodies targeted to the GABAAR.These two patients had onset symptom of seizure or refractory seizures.Memory impairment,psychiatric symptoms and decreased consciousness were also presented.One patient was combined with mass in anterior superior mediastinum.Both patients had multifocal cortical and subcortical T2 /fluid attenuated inversion recovery-weighted images hyperintensity signal on brain magnetic resonance imaging.The two patients had poor response to antiepileptic drugs,but showed noticeable recovery with sufficient immunotherapeutic treatments.Conclusions Anti-GABAAR encephalitis is characterized by prominent epilepsy and multifocal abnormalities on brain magnetic resonance imaging.Autoantibodies specifically against GABAAR could be detected by CBA in this group of patients.Early diagnosis and immunotherapy are critical to improve clinical symptoms and outcomes of the disease.

Objective To evaluate the clinical effect of deep acupuncture at Lianquan (CV23) combined with swallowing rehabilitation training in the treatment of dysphagia after stroke.Methods A total of 84 patients with dysphagia after stroke who met the inclusion criteria were divided into 2 groups, 42 in each. The control group received swallowing rehabilitation training, and the observation group was treated with acupuncture therapy based on deep acupuncture atLianquan (CV23) combined with swallowing rehabilitation training. The VFSS score and clinical efficacy were compared between the 2 groups before and after treatment.Results The cure rate of observation group was 69.1% (29/42), the total effective rate 85.7% (36/42), while the control group were 42.86% (18/42) and 66.67% (28/42). The comparison of cure rate and total efficiency rate between the two group had statistically significant differences (χ2=5.845, 4.200,P=0.016, 0.040). After treatment, the VFSS score of the observation group was significantly higher than that of the control group (7.43 ± 2.27vs.4.31 ± 1.53;t=5.433, P<0.05). The recovery time of the 29 cured patients in the observation group was (12.0 ± 3.0) d, while the recovery time of the 18 cured patients in the control group was (17.8 ± 2.2) d. There was statistically significant difference between the 2 groups (t=7.094,P=0.001).Conclusions Deep acupuncture at Lianquan (CV23) combined with swallowing rehabilitation training can improve the swallowing function of patients with dysphagia after stroke, shorten the recovery time of swallowing function and improve the clinical efficacy.

OBJECTIVETo observe the clinical efficacy of deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training for post-stroke dysphagia.

METHODSSixty cases of post-stroke dys phagia were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the observation group, based on the regular acupuncture treatment, were treated with deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17), once a day, 30 min per treatment; also swallowing training was combined, twice a day, 20 min per treatment. Patients in the control group were treated with swallowing training. All the patients were treated with regular treatment of stroke. Six days of treatment were taken as one session, and totally 3 sessions were given with an interval of one day between sessions. The video fluoroscopic swallowing study (VFSS) dysphagia evaluation scale and Watian water swallow test (WWST) were evaluated before and after treatment also the clinical efficacy and the recovery time of two groups were compared.

RESULTSAfter treatment, the VFSS score in the observation group was significantly superior to that in the control group (P < 0.01); the WWST in the observation group was significantly superior to that in the control group (P < 0.01). The cured rate was 70.0% (21/30) in the observation group, which was significantly superior to 43.3% (13/30) in the control group (P < 0.01); the total effective rate was 86.7% (26/30) in the observation group, which was significantly superior to 66.7% (20/30) in the control group (both P < 0.01). The clinical recovery time in the observation group was significantly shorter than that in the control group (P < 0.01).

CONCLUSIONDeep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training could effectively improve post-stroke swallow function.
