Stroke is characterized by a group of acute cerebral vascular diseases which attack acutely with focal neurological deficits. Residual motor deficits often sojourn after stroke. Cortical stimulation, which is a technique developed many decades ago, has recently re-emerged as a promising method for researchers in their quest to causally probe cortical representations of sensorimotor and cognitive functions and to facilitate the treatment of various neuropsychiatric disorders. The article summarizes the research progress of cortical stimulation in the promotion of motor function recovery after stroke, the method of operation, the possible mechanisms and the prospect.

0 05). No postoperative pyrexia and severe complications occurred in all the four groups. Conclusions The four procedures are all safe and feasible. The selection of these procedures is based on the patient’s individual conditions.

Objective:To study the clinical features and treatment outcome of AIDS associated oral candidiasis.Methods:The clinical data of 31 cases with AIDSassociated oral candidiasis from 201209 to 201303 were studied retrospectively,including general data,clinical features,oral manifestation,CD4 cell count,opportunistic infections,and antifungal therapy outcome,etc.Results:CD4cell count ＜200 cell/μl was found in 30 cases,AIDSrelated multiple opportunistic infection was observed in 29 cases.30 cases hadpseudomembranous candidiasis,1 cases had erythematous candidiasis and 2 cases had pseudomembranous candidiasis with angular candidiasis.After antifungal treatment,the lesion of 8 cases reduced,that of 23 cases disappeared completely,lesion relapse after drugwithdrawal happened in 3 cases.Conclusion:AIDSassociated oral candidiasis was more common in AIDS patients with CD4 ＜200cells/μl,the main clinical form is pseudomembranous type,and with multiple opportunistic infections.The antifungal treatment is effective for the patients.

Objective To understand the clinical features of patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) complicated by cytomegalovirus (CMV)viremia.Methods The clinical data of 249 cases of HIV/AIDS patients hospitalized in Beijing Ditan Hospital from Oct 2008 to Nov 2009 were analyzed retrospectively,in which 43 HIV/AIDS patients were diagnosed with CMV viremia.The symptoms and signs,cerebrospinal fluid (CSF)tests,and pathological detections by bronchoscope,gastroscope and fibercoloscope were collected.The database was set up using Excel software.The association between cellular immunity and CMV DNA level was determined by SPSS12.0 software.Results Forty-three patients (17.3%)were diagnosed with CMV viremia by positive results of CMV pp65 antigen and CMV DNA tests; 14 patients manifested retinal bleeding or infiltration and 4 patients displayed retinal fibrosis; 1 patient was diagnosed with CMV pneumonitis by pathological results of bronchoalveolar lavage fluid.Low level of CD4+ T lymphocytes and CMV DNA levels were positively correlated.Conclusions CMV pp65 antigen and CMV DNA should be detected in HIV/AIDS patients with CD4+ T lymphocytes less than 100 × 106/L and anti-CMV treatment should be given according to the results.Ophthalmologic examination and bronchoalveolar lavage fluid pathological detection are effective methods in diagnose of CMV retinitis and pneumonitis.

Objective To discuss the feasibility and curative effect of intra-radiation stenting(125Iparticle stent)for the treatment of advanced esophageal cancers.Methods Fifteen patients with advanced esophageal cancer were enrolled in this study.Under X-ray guidance the esophageal stent,which was tied up with 125I radioactive particles,was orally inserted to the diseased region of the esophagus.The clinical manifestations and imaging findings were observed and the results were analyzed.Results After the operation all the clinical symptoms such as dysphasia showed an obvious improvement.No serious complications such as infection,hemorrhage,radiation pneumonia,etc.Occurred.The re-examination at 3-6 months after the treatment showed that the tumor size Was decreased in a certain degree in 14 patients,and in the remaining one patient the lesion became bigger and grew to the upper opening of the stent,resulting in esophageal restenosis.Conclusion The intra-esophageal implantation of radioactive stent is a feasible and safe treatment for the advanced esophageal cancers with excellent curative results.

Objective To evaluate the treatment effects of chemotherapy comparing with chemotherapy and radiotherapy in the limited-stage small cell lung cancer (SCLC). Methods 234 patients were cyto-pathologically diagnosed and staged as limited small cell lung cancer. The patients were treated with combined chemotherapy and radiotherapy,in which 22 cases were treated by alone chemotherapy (C),39 patients by chemotherapy plus radiotherapy(C+R),and 173 cases by combined chemotherapy and radiotherapy + chemotherapy (C+R+C). The chemotherapy regimen included CE (or PE),CAP or CAV for 4~6 cycles. Irradiation treatment covering the primary tumor,the ipsilateral hilar nodes and mediastinum was delivered once daily with 6 megavoltage X-ray beam to a median irradiation does of 56 Gy being given in 5~6 weeks. Results The 1-,2-,3-,and 5-year overall survival rates were 76.5%,38.2%,25.3%,15.6% respectively,and the median survival time (MST) was 19 months. There was a significantly difference on the survival rate between C+R+C group and C+R group or C group (P

BACKGROUND: This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings. METHODS: We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022. RESULTS: Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001). CONCLUSION The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

Incidence of hypophosphatemia: group Ⅰ 7/106 (6.6%), group Ⅱ 7/134 (5.2%), group Ⅲ 12/123 (9.8%), group Ⅳ 6/61 (9.8%), P=0.478; incidence of hyperuricemia: groupⅠ26/106 (24.5%), group Ⅱ 35/134 (26.1%), group Ⅲ 28/123 (22.8%), group Ⅳ 10/61 (16.4%), P=0.508; incidence of diabetes: groupⅠ1/106 (0.9%), group Ⅱ 9/134 (6.7%), group Ⅲ 6/123 (4.9%), group Ⅳ 3/61 (4.9%), P=0.140; incidence of GGT > 60 U/L: group Ⅰ(21.7%), 23 group Ⅱof 34 (25.4%), 25 group Ⅲ (20.3%), group Ⅳ of 12 (19.7%), P=0.736; incidence of ALT > 50 U/L: groupⅠ(21.7%), 23 group Ⅱ of 33 (24.6%), group Ⅲ of 24 (19.5%), group Ⅳ of 12 (19.7%), p=0.761Conclusion:The types of dyslipidemia in HIV/AIDS patients treated for more than half a year are mainly low HDL-C and hypertriglyceridemia, and the incidence of dyslipidemia does not increase with the prolonging of treatment. It showed a decreasing trend of eGFR with the prolongation of treatment and the occurrence of hypophosphatemia and hyperuricemia should be concerned. The damage of ART drugs to liver function persisted during treatment.

Objective To understand the high incidence of pharyngeal ulcer in patients with acquired immune deficiency syndrome (AIDS).By analyzing the clinical features in AIDS patients with pharyngeal ulcer,this study provided reference for clinicians.Methods Twenty AIDS patients with pharyngeal ulcer were retrospectively analysed to explore its clinical features and mechanism,and to explore the feasible therapeutic methods.Results The patients generally had severe sore throat and dysphagia for 7 days to 8 months,resulting in significant weight loss.Common therapeutical method does not work.The ulcers developed mainly at vestibule of pharynx (10 cases),tonsil (3 cases),epiglottis (3 cases) and pyriform sinus (2 cases).Ulcer types included major aphthous ulcer (MaAU,14 cases),fungal ulcer (2 cases),herpes zoster (1 case),ulcer secondary to drug eruption(1 case),and lymphoma(2 cases).The disease course was long with CD4 + T lymphocytes decreased significantly.Treatment was given with highly active antiretroviral therapy (HARRT),regulation of immune function,analgesic,anti-inflammatory and anti fungal.Treatment lasted from 2 weeks to 3 months,ulcer healed in 13 cases; 1 patient lost to follow-up,6 patients dead.Conclusions The manifestation of pharyngeal ulcer in AIDS patients has its particularity.It is often associated with a variety of opportunistic infection and tumors.Local treatment is preferred.HAART therapy and systemic comprehensive treatment play more important and effective role.Pharyngeal ulcer persists for a long time,complicated with fever,diarrhea and other symptoms.The history of blood transfusion,injection drug use or unsafe sexual behavior may predict HIV infection.

Chlorfenapyr,an emerging synthetic pesticide,has been linked to a growing number of poisoning incidents,attributed to heightened human exposure as its application becomes more widespread.However,the toxicokinetics and toxicology of chlorfenapyr remain incompletely understood.Research since the 1990s,including animal experiments,has illuminated the absorption,distribution,excretion,and metabolism of chlorfenapyr.Toxicological investigations have revealed that the primary toxicity of chlorfenapyr is the uncoupling of oxidative phosphorylation.Chlorfenapyr exposure in humans and other animals can lead to various toxic effects,including neurotoxicity,cardiotoxicity,skeletal muscle toxicity,genotoxicity,reproductive and developmental toxicity,renal toxicity,splenic toxicity,and hematotoxicity.This article presents a comprehensive review of the toxicokinetics and toxicology of chlorfenapyr,integrating data from animal experiments,human cell line studies,clinical reports,and human autopsy.Its objective is to raise clinical awareness regarding chlorfenapyr poisoning and offer valuable references for its treatment and management.
