OBJECTIVE: To explore the relationship between spinous process deviation and lumbar disc herniation in young patients. METHODS: From March 2015 to January 2022, 30 treated young (under the age of 30) patients with lumbar disc herniation were included as the young group. In addition 30 middle-aged patients (quinquagenarian group) with lumbar disc herniation and 30 patients with non-degenerative spinal diseases (young non-degenerative group) were selected as control groups. The angle of the spinous process deviation was measured on CT and statistically analyzed by various groups. All the data were measured twice and the average value was taken and recorded. RESULTS: The average angle of spinous process deviation in the degenerative lumbar vertebra of young patients were (3.89±3.77) degrees, similar to the (3.72±2.98) degrees of quinquagenarian patients(P=0.851). The average angle of s spinous process deviation young non-degenerative group were (2.20±2.28) degrees, significantly less than young group(P=0.040). The spinous process deviation angle of the superior vertebral of the degenerative lumbar in the young group was (4.10±3.44) degrees, which similar to the (3.47±2.87) degrees in the quinquagenarian group (P=0.447). A total of 19 young patients had the opposite deviation direction of the spinous process of the degenerative lumbar vertebra and upper vertebra, while only 7 quinquagenarian patients had this condition(P=0.02). The type of lumbar disc herniation in young patients had no significant relationship with the direction of spinous process deflection of the degenerative or upper lumbar vertebra (P>0.05). CONCLUSION Spinous process deviation is a risk factor of young lumbar disc herniation patients. If the deviation directions of adjacent lumbar spinous processes are opposite, it will increase the incidence of lumbar disc herniation in young patients. There was no significant correlation between the type of disc herniation and the deviation direction of the spinous process of the degenerative or upper lumbar vertebra. People with such anatomical variation can strengthen the stability of spine and prevent lumbar disc herniation through reasonable exercise.

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 evaluate the safety and efficacy of the seven-step two-lobe holmium laser enucleation of the prostate (HoLEP) technique with low power laser device, and to introduce the detailed operating procedures, key points, short-term outcomes of this modified HoLEP technique. METHODS: From March 2016 to November 2017, 90 patients underwent HoLEP in Peking University Third Hospital. The patients were divided into two groups: high-power group (32 patients) were performed with traditional Gilling's three-lobe enucleation using high power (90 W) laser; Low-power group (58 patients) were performed with seven-step two-lobe enucleation using low power (40 W) laser. The main steps of the low power seven-step two-lobe HoLEP phase included: (1) The identification of the correct plane between adenoma and capsule at 5 and 7 o'clock laterally to the veru montanum; (2) The connection of the bilateral plane by making a adenoma incision at the proximal point of veru montanum; (3) The extension of the dorsal plane under the whole three lobes between adenoma and capsule towards the bladder neck; (4) The separation of the middle lobe from two lateral lobes by making two retrograde incisions separately from apex 5 and 7 o'clock towards the bladder neck; (5) The enucleation of the middle lobe adenoma by extending the dorsal plane through into the bladder; (6) The prevention of the apex mucosa by making a circle incision at the apex of the prostate; (7) The en-bloc enucleation of the two lateral lobe adenomas by extending the lateral and ventral plane between adenoma and capsule from 5 and 7 o'clock to 12 o'clock conjunction and through into the bladder. RESULTS: The mean patient age was (66.25±5.37) years vs. (68.00±5.18) years; The mean body mass indexes were (24.13±4.06) kg/m² vs. (24.57±3.50) kg/m²; The mean prostate specific antigen values were (3.23±2.47) μg/L vs. (6.00±6.09) μg/L; The average prostatic volumes evaluated by ultrasound was (49.03±20.63) mL vs. (67.55±36.97) mL. There was no significant difference between the two groups. Furthermore, there were no significant differences in terms of perioperative and follow up data, including operative time; enucleation efficiencies; hemoglobin decrease; blood sodium and potassiumthe change postoperatively; catheterization duration and hospital stay; the international prostate symptom scores and quality of life scores pre- and post-operatively. There was 1 transurethral resection of the prostate (TURP) conversion in high-power group and 1 transfusion in low-power group during the operations. The follow-up one month after operation showed no severe stress incontinence in both the groups, whereas 3 cases ejaculatory dysfunctions in high-power group versus 1 case in low-power group were observed; Other surgeryrelated complications included: 2 cases postoperative hemorrhage (Clavien II and Clavien IIIb) in high-power group, 2 cases postoperative temperature more than 38 °C (Clavien I) and 1 case dysuria following catheter removal (Clavien I) in low-power group. CONCLUSION Low power laser device can be applied safe and effectively for HoLEP procedure using the seven-step two-lobe HoLEP technique. The outcomes comparable with high power laser HoLEP can be achieved.

OBJECTIVE: The association between lipoprotein (a) [Lp(a)] levels and metabolic syndrome (MetS) remains uncertain, especially in the Asian population. The purpose of this study was to demonstrate the association between Lp(a) levels and MetS in a middle-aged and elderly Chinese cohort. METHODS: A cross-sectional study of 10,336 Chinese adults aged 40 years or older was conducted in Jiading District, Shanghai, China. Logistic regression analysis was used to evaluate the association between serum Lp(a) levels and MetS. RESULTS: In the overall population, 37.5% of participants had MetS. Compared with individuals in the lowest quartile of serum Lp(a) levels, those in the highest quartile had a lower prevalence of MetS (30.9% vs. 46.9%, P for trend < 0.0001). Multivariate logistic regression analyses showed that compared with participants in the bottom quartile of serum Lp(a) levels, those in the top quartile had decreased odds ratio (OR) for prevalent MetS [multivariate-adjusted OR 0.45 (95% confidence interval 0.39-0.51); P < 0.0001]. Additionally, Lp(a) level was conversely associated with the risk of central obesity, high fasting glucose, high triglycerides, and low HDL cholesterol, but not with hypertension. Stratified analyses suggested that increasing levels of Lp(a) was associated with decreased risk of MetS in all the subgroups. CONCLUSION Serum Lp(a) level was inversely associated with the risk of prevalent MetS in a middle-aged and elderly Chinese cohort.

BACKGROUND: The treatment of degenerative knee osteoarthritis is mainly to relieve pain, restore knee function, improve quality of life, delay knee replacement, and reduce the number of revisions. Knee replacement is currently the most common treatment for this disease, but it costs much, has great trauma and high risk, often results in prosthesis loosening and peripheral infection, and has many adverse reactions. OBJECTIVE: We hypothesize that knee-preserving arthroscopic debridement for treatment of knee degenerative osteoarthritis in the elderly patients costs less, is effective, safe, and reliable. METHODS: A total of 212 elderly patients (knees) with degenerative knee osteoarthritis who receive treatment in the Second Hospital of Chaoyang (Liaoning Province, China) will be included in this study. These patients will be assigned to two groups according to patient's conditions and wishes (n = 106/group). In the control group, intra-articular injection of sodium hyaluronate will be performed, followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. In the arthroscopic debridement group, arthroscopic debridement will be performed followed by oral administration of non-steroidal anti-inflammatory drugs, conventional physiotherapy, and quadriceps functional exercise. All patients will be followed up for 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years. RESULTS AND CONCLUSION: The primary outcome measure is the percentage of the number of patients with Hospital for Special Surgery (HSS) knee score ≥ 85 points at 2 years after surgery, which will be used to evaluate knee function recovery. The secondary outcome measures are the percentage of the number of patients with HSS knee score ≥ 85 points before surgery, 1 week, 1 month, 3 months, 6 months, and 1 year after surgery; HSS score, Visual Analogue Scale (VAS) score, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), knee range of motion, hospitalization costs, and knee X-ray morphology before surgery, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery, medical costs after 2 years of treatment, incidence of adverse reactions at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after surgery. Findings from this study will reveal whether arthroscopic debridement for the treatment of degenerative knee osteoarthritis in the elderly patients has advantages of less adverse reactions, low treatment costs, and can effectively restore knee function.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4％,48. 9％,39. 3％,and 30. 9％,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5％,41.5％,35.2％,and 30％,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.
