BACKGROUND:Spinal canal decompression using uniportal endoscopic surgery is a new minimally invasive surgery in the treatment of lumbar spinal stenosis.However,this technique needs a steep learning curve and high requirements for surgical equipment and instruments,which limits its clinical application.We previously use the spinal endoscopy as a monitoring endoscopy and combined with unilateral biportal endoscopy to propose a hybrid technique of spinal endoscopy to achieve coaxial endoscopic operation and hands-separate operation. OBJECTIVE:To compare the clinical outcome of hybrid technique and uniportal endoscopic surgery in treatment of lumbar spinal stenosis with bilateral lower limb pain symptoms. METHODS:Ninety patients diagnosed of lumbar spinal stenosis with bilateral symptoms were included and retrospectively analyzed at First People's Hospital,Shanghai Jiao Tong University from August 2020 to August 2022.44 cases were included in group A(hybrid technique group),while 46 cases were included in group B(uniportal endoscopic surgery).The nerve decompression was observed during the surgery.Operation time,hospital stay time,and expenses were recorded in both groups.The visual analog scale scores of lower back pain and both lower extremities pain,Oswestry disability index scores of quality of life and excellent and good rate of modified Macnab criteria were recorded and compared at preoperative,postoperative 3 days,and postoperative 3 and 6 months. RESULTS AND CONCLUSION:(1)The operation time of group A was significantly shorter than that of group B(P<0.05).(2)The lower back pain and lower extremity pain of the severe side at postoperative 3 days,and 3 and 6 months were significantly relieved in both groups(P<0.05).The visual analog scale score of lower extremity pain on the mild side was significantly decreased at postoperative 3 days,3 and 6 months than preoperative score in the group A(P<0.05).The visual analog scale score of lower extremity pain on the mild side was significantly decreased at postoperative 3 days than preoperative score in the group B(P<0.05).The visual analog scale scores of lower extremity pain on the mild side at postoperative 3 and 6 months did not show significant difference than preoperative score in the group B.The comparison between the two groups showed that there was no significant difference in the visual analog scale scores of postoperative lower back pain and lower extremity pain of the severe side(P>0.05).The visual analog scale scores of lower extremity pain on the mild side in the group A were significantly lower than those of group B at postoperative 3 and 6 months(P<0.05).(3)The Oswestry disability index scores of both groups at postoperative 3 day were significantly lower than preoperative score(P<0.05),and there was no significant difference between the two groups 3 days after operation.Oswestry disability index scores of group A at postoperative 3 and 6 months were significantly decreased than preoperative score(P<0.05).The Oswestry disability index scores of group B at postoperative 3 and 6 months did not show significant differences than preoperative score(P>0.05).The comparison between the two groups showed the Oswestry disability index scores of group A were significantly lower than group B at postoperative 3 and 6 months(P<0.05).(4)The results of modified Macnab showed that the excellent and good rate of group A was significantly higher than that of group B(95%,78%,P<0.05).(5)It is indicated that the hybrid technique is a new spinal endoscopy technique,which has the advantages of less trauma and faster recovery as a minimally invasive surgery.The clinical outcome of hybrid technique is superior to that of uniportal endoscopic surgery in the treatment of lumbar spinal stenosis with bilateral symptoms.Additionally,it also has the advantages of good operational flexibility and high decompression efficiency as an open surgery.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Objective:To analyze the clinical symptoms and epidemiological characteristics of patients with tsutsugamushi disease (TD) in Utica County, Shiyan City, providing reference for scientific prevention and control of TD.Methods:The information of 57 TD patients admitted to the Department of Infectious Diseases of the People's Hospital of Utica County in Shiyan City from January to December 2022 was collected, including age, gender, occupation, clinical manifestations (tarsus or chigger, high fever, rash and accompanying syndromes), laboratory and imaging test results, and field work and travel history. Blood samples and body crusts were collected, and enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) were used to detect antibodies against Orientia tsugamushi (Ot-Ab-IgM) and Orientia tsutsugamushi (Ot). The scores of each patient were calculated using the TD Diagnostic Scale. A score of ≥8.5 was considered a clinical diagnosis of TD. According to the number of system functional damages (0, 1, 2, ≥3), 57 patients were divided into 4 groups, A, B, C, and D, TD was analyzed for system functional damages of each system.Results:Among the 57 TD patients, 26 (45.61%) were male and 31 (54.39%) were female, and the proportion of patients aged 40 - 79 years was 92.98% (53/57); farmers accounted for 89.47% (51/57). May was the peak of TD incidence, with 19 cases, which accounted for 33.33% (19/57) of the total number of patients affected that year. Fifty-four patients had a history of fieldwork or field trips before the onset of the disease. The incidence of high fever in 57 TD patients was 100.00%(57/57), the detection rate of body scorch or chiggers was 80.70% (46/57), and the incidence rate of rash was 98.25% (56/57); the incidence rate of tsutsugamushi disease triad (accompanied by scabs, high fever, and rash) was 80.70% (46/57); the incidence of eosinophil decline was 100.00%(57/57), and 77.19% (44/57) of TD patients experienced multiple-system functional damage (MSFD). The TD score diagnostic scale for 57 patients ranged from 8.5 to 10.5 points. After being hospitalized for 1 - 5 days, all TD patients experienced a decrease in body temperature to the normal range, and the damage to various systems functional gradually recovered.Conclusions:TD has become one of the most common natural infectious diseases in Utopia County, Shiyan City, Hubei Province. The patients are mainly middle-aged and elderly people, and the triple syndrome is a typical clinical manifestation. Asymptomatic injuries to the blood system, liver and kidneys are the most common.

Objective:To analyze the differences in paraspinal muscles between patients with degenerative lumbar spinal stenosis (DLSS) with or without spondylolisthesis and to assess the correlation between these differences and lumbar facet joint degeneration.Methods:The data of 68 patients with DLSS who underwent surgical treatment in our hospital from January 2021 to April 2023 was retrospectively analyzed. Of these, 22 were male (32.4%) and 46 were female (67.6%), with an average age of 69.7±5.9 years (range: 56-80 years). The DLSS group included 35 patients without spondylolisthesis [13 males (37.1%) and 22 females (62.9%)], average age 68.5±5.9 years (range: 56-80 years), while the DLSS+degenerative spondylolisthesis (DS) group included 33 patients with spondylolisthesis [9 males (27.3%) and 24 females (72.7%)], average age 70.9±5.7 years (range: 58-80 years). Magnetic resonance imaging (MRI) scans of the L 3-S 1 intervertebral disc levels were collected from all patients. Using ImageJ software, the cross-sectional area (CSA) and percentage of fat infiltration area (FIA%) of the erector spinae and multifidus muscles were measured. Additionally, the facet joint angle (FJA), facet overhang (FO), and facet effusion (FE) were evaluated using Surgimap software, and their correlation with CSA and FIA% of the paraspinal muscles was analyzed. Results:The FJA and FO in the DLSS+DS group (50.16°±11.08° and 7.67±2.25 mm) were significantly larger than those in the DLSS group (43.51°± 7.75° and 3.88±1.98 mm) ( P<0.05). However, differences in FE between the two groups were not statistically significant. The cross-sectional areas of the multifidus muscles at L 3, 4, L 4, 5, and L 5S 1 in the DLSS+DS group (576.66±112.70 mm 2,, 782.72±141.49 mm 2, and 817.88±185.22 mm 2,, respectively) were significantly smaller than those in the DLSS group (647.37±165.44 mm 2,, 881.20±202.10 mm 2,, and 995.06±211.25 mm 2,, respectively) ( P<0.05). The FIA% of the erector spinae at L 3, 4, L 4, 5, and L 5S 1 in the DLSS+DS group (11.47%±5.14%, 14.84%±6.15%, 20.82%±7.41%) were significantly higher than those in the DLSS group (6.27%±2.83%, 10.81%±4.84%, 16.17%±5.88%) ( P<0.05). Similarly, the FIA% of the multifidus muscles at L 3, 4, L 4, 5, and L 5S 1 in the DLSS+DS group (18.04%±5.88%, 19.67%±5.78%, 19.31%±8.61%) were significantly higher than those in the DLSS group (9.85%±4.39%, 12.27%±3.70%, 14.65%±3.82%) ( P<0.05). No statistically significant differences were found in the CSA of the erector spinae at these levels between the two groups. The CSA of the multifidus muscles at L 3, 4, L 4, 5, and L 5S 1 in both groups were negatively correlated with FJA and FO ( r=-0.318, P=0.008; r=-0.381, P=0.001; r=-0.439, P<0.001; r=-0.290, P=0.016; r=-0.315, P=0.009; r=-0.479, P<0.001). The FIA% of the erector spinae at L 3, 4, L 4, 5, and the multifidus muscles at L 4, 5 and L 5S 1 were positively correlated with FJA ( r=0.352, P=0.003; r=0.344, P=0.004; r=0.300, P=0.013; r=0.359, P=0.003). Additionally, the FIA% of the erector spinae at L 3, 4, L 4, 5, and L 5S 1, and the multifidus muscles at L 3, 4 and L 4, 5 were positively correlated with FO ( r=0.409, P=0.001; r=0.248, P=0.042; r=0.277, P=0.022; r=0.500, P<0.001; r=0.447, P<0.001). There was no correlation between FE and CSA or FIA% of the erector spinae and multifidus muscles at L 3, 4, L 4, 5, and L 5S 1 in either group. Furthermore, FJA was positively correlated with FO ( r=0.369, P=0.002), but no correlation was observed between FE and FJA or FO. Conclusion:Compared to patients with lumbar spinal stenosis, those with degenerative lumbar spinal stenosis with spondylolisthesis exhibit more severe paraspinal muscle atrophy, a more sagittal orientation of the facet joints, and a higher degree of facet joint osteoarthritis. Patients with larger FJA and FO show more severe paraspinal muscle atrophy.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To investigate the application value of Overlap guiding tube (OGT) in Overlap esophagojejunostomy of laparoscopic total gastrectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 5 patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June to July in 2021 were collected. There were 3 males and 2 females, aged from 48 to 61 years, with a median age of 54 years. Patients underwent laparoscopic total gastrectomy combined with OGT-assisted Overlap esophagojejunostomy. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination and telephone interview to detect postoperative anastomotic stenosis and esophageal reflux up to September 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(IQR) or M(range). Count data were represented as absolute numbers. Results:(1) Surgical situations: 5 patients underwent laparoscopic total gastrectomy combined with OGT-assisted Overlap esophagojejunostomy and D 2 lymph node dissection success-fully, achieving R 0 resection. There was no combined organ resection, intraoperative conversion to laparotomy or combined thoracotomy. There was no intraoperative conversion to other esophagoje-junostomy method either. The tumor diameter, length of surgical incision, the number of lymph nodes dissected, time of esophagojejunal anastomosis, time of digestive reconstruction, operation time, volume of intraoperative blood loss of 5 patients were 3.0(2.8)cm, 5.0(2.0)cm, 47.0(21.0), 21.0(5.0)minutes, 62.0(23.0)minutes, 295.0(75.0)minutes, and 50.0(60.0)mL, respectively. The anvil fork of linear stapler was successfully inserted into esophageal lumen by once operation in 4 cases of 5 patients and by twice operation in 1 case to complete the esophagojejunostomy. (2) Post-operative situations: the time to first out-of-bed activities, time to postoperative first anal flatus, time to postoperative initial liquid diet intake, time to postoperative initial semi-liquid diet intake, time to abdominal drainage tube removal, duration of postoperative hospital stay of 5 patients were 2.0(1.0)days, 3.0(2.0)days, 4.0(3.0)days, 6.0(3.0)days, 7.0(4.0)days, and 9.0(6.0)days, respectively. Results of postoperative pathological examination of 5 patients showed gastric adenocar-cinoma in all the 5 patients, with the TNM staging as stage pT2-4aN0M0. The esophageal surgical margin was negative in all cases, and the length of proximal margin from esophagus was 5.0(4.0)cm. None of the 5 patients developed anastomotic leakage, anastomotic bleeding or anastomotic stenosis. Two cases with mild pneumonia (Clavien-Dindo grade Ⅱ) were cured by conservative treatment such as anti-infection and expectoration promotion. There was no unplanned secondary surgery or perioperative death occurred to the 5 patients. (3) Follow-up: 5 patients were followed up for 3 months. None of the 5 patients developed anastomotic stenosis or esophageal reflux during the follow-up. Conclusion:OGT-assisted Overlap esophagojejunostomy of laparoscopic total gas-trectomy is safe and feasible, with good short-term effects.

OBJECTIVE: To evaluate whether the efficacy of Getong Tongluo Capsule (, GTC, consisted of total flavone of Radix Puerariae) on improving patients' quality of life and lowering blood pressure are superior to the extract of Ginkgo biloba (EGB) for patients with convalescent-phase ischemic stroke and primary hypertension. METHODS: This randomized, positive-drug- and placebo-controlled, double-blind trial was conducted from September 2015 to October 2017. Totally 477 eligible patients from 18 hospitals in China were randomly assigned in a 2:1:1 ratio to the following interventions, twice a day for 12 weeks: (1) GTC 250 mg plus EGB-matching placebo 40 mg (237 cases, GTC group), (2) EGB 40 mg plus GTC-matching placebo 250 mg (120 cases, EGB group) or (3) GTC-matching placebo 250 mg plus EGB-matching placebo 40 mg (120 cases, placebo group). Moreover, all patients were orally administered aspirin enteric-coated tablets 100 mg, once a day for 12 weeks. The primary outcome was the Barthel Index (BI). The secondary outcomes included the control rate of blood pressure and National Institutes of Health Stroke Scale (NIHSS) scores. The incidence and severity of adverse events (AEs) were calculated and assessed. RESULTS: The BI relative independence rates, the clinical recovery rates of NIHSS, and the total effective rates of NIHSS in the GTC and EGB groups were significantly higher than the placebo group at 12 weeks after treatment (P<0.05), and no statistical significance was found between the GTC and EGB groups (P>0.05). The control rate of blood pressure in the GTC group was significantly higher than the EGB and placebo groups at 12, 18 and 24 weeks after treatment (P<0.01). There were no statistically significant differences in the incidences of AEs, adverse drug reactions, or serious AEs among the 3 groups (P>0.05). CONCLUSION GTC exhibited significant efficacy in improving patients' quality of life as well as neurological function and controlling hypertension. (Registration No. ChiCTR1800016667).

Objective: To investigate the middle ear function of the patients with cleft palate pre and post palatoplasty. Methods: 76 patients with cleft palate were investigated by clinical history and audiology examinations including electric otoscopy,tympanometry and click-ABR threshold. Results: The risk for middle ear function decreased with advancing age in the first 5 years. It was noticed that the otologic outcomes was related to the CP type. During long time follow-up, the frequency with the middle ear function disorder was always high within the CP patients but the proportion of the patients received tympanostomy tubes was low relatively. The prevalence of middle ear dysfunction did not differ with the time of cleft palate repair. Conclusion: The patients with cleft palate have middle ear function dysfunction in a long period of time,therefore a standard long-time follow-up system is necessary.
