RESUMEN

Objective To investigate the relieving effects of knockdown of long non-coding RNA(lncRNA)taurine up-regulated gene 1 (TUG1) on inhibiting nucleotide binding oligomerization domain like receptor protein 1 (NLRP1) inflammasome and the progression of Alzheimer’ s disease. Methods Wild-type (WT group, 10 mice) or amyloid precursor protein (APP) / presenilin-1 (PS1) transgenic mice (30 mice) with a genetic background of C57 / BL6 aged 9-10 weeks were used in this study. APP / PS1 transgenic mice were randomly divided into model group, model+lncRNA TUG1 short hairpin RNA (shRNA) group and model + shRNA non target (NT) group (n = 10) . Blood samples, cerebral cortex tissues, primary microglial cells and primary astrocytes were collected from mice 12 weeks of age on day 1 (3-month-old) and 32 weeks of age on day 1 (8-month-old), with 5 mice per group at each time point. Real-time PCR analysis was used to detect the expression levels of lncRNA TUG1 and macrophage migration inhibitory factor (MIF) mRNA in cerebral cortex tissues and primary microglial cells, and C1r and C1s mRNA levels in primary astrocytes of 3-month-old and 8-month-old mice in the above 4 groups, respectively. ELISA was used to determine the MIF in plasma samples of the above 4 groups of mice. Primary microglia and astrocytes from the cerebral cortex of 3-month-old and 8-month-old mice were co-cultured. CCK-8 method was used to determine the proliferation ability of the above cells. Western blotting was used to determine the expression levels of MIF, pro interleukin-1β (pro-IL-1β), apoptosis associated speck-like protein containing a caspase recrult domain(ASC), Caspase-1 (p20), Caspase-1 (full), NLRP1 and NLRP3 in cerebral cortex tissues of 3-month-old and 8-month-old mice. Immunofluorescent staining was used to determine amyloid beta(Aβ) in cerebral cortex of 8-month-old mice. Results At the age of 3-month-old and 8-month-old, compared with the WT group, the relative expression level of lncRNA TUG1 and MIF in cerebral cortex tissues and primary microglia of model group mice was significantly up-regulated, with primary microglial cells and astrocytes proliferation ability enhanced (P0. 05) . There was no significant difference between the model group and the model+shRNA NT group mice of all the above factors (P>0. 05) . Conclusion In APP / PS1 transgenic mice, up-regulation of lncRNA TUG1 and MIF are positively associated with the activation of NLRP1 inflammasome in mice cerebral cortex tissues and primary microglia. Knock-down of lncRNA TUG1 can ameliorate the progression of Alzheimer’ s disease.

RESUMEN

OBJECTIVE@#To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities.@*METHODS@#The AlCl3 colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C18 column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking.@*RESULTS@#Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile.@*CONCLUSION@#The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.

RESUMEN

ObjectiveTo analyze the causes of death and years of life lost among patients with severe mental disorders in Jining city, in order to provide references for improving the management level of the patients. MethodsA total of 3 638 patients with severe mental disorders who were recorded in the National Information System for Severe Mental Disorders in Jining and died between January 1, 2014 and December 31, 2020 were included in the study. The general information and the status of mortality were extracted via checking management files. Thereafter, the causes of death of patients with different characteristics were discussed, and the years of life lost due to severe mental disorders was analyzed through calculating potential years of life lost (PYLL), average years of life lost (AYLL) and potential years of life lost rate (PYLLR). ResultsThe majority of patients who died from severe mental disorders were those with schizophrenia, accounting for 77.68% (2 826/3 638). The most common cause of death among patients with severe mental disorders was physical illness with 1 869 cases (51.37%). Among the selected subjects, patients with mental retardation and comorbid mental disorders had the youngest age of disease onset [(22.49±20.14) years], the youngest age at death [(51.72±18.32) years] and the longest duration of disease [(29.26±19.35) years]. The PYLL, AYLL and PYLLR of patients with severe mental disorders in Jining were 68 941.06 person-years, 18.95 years and 382.36‰, respectively. The mental retardation and comorbid mental disorders had the highest AYLL at 27.21 years, and epilepsy-induced mental disorder had the highest PYLLR at 892.73‰. ConclusionComorbid physical illness is the main causes of death in patients with severe mental disorders in Jining city, and epilepsy-induced mental disorder have occupied the first place in terms of the years of life lost.

RESUMEN

OBJECTIVE@#To evaluate the effects of electromyography on the clinical manifestations and prognosis after posterior lumbar interbody fusion(PLIF) of degenerative lumbar diseases.@*METHODS@#A retrospective analysis was performed on 68 patients with degenerative lumbar diseases, including 29 males and 39 females, aged 21 to 84 years old, who underwent electromyogram (EMG) from January 2018 to October 2019. The patients were divided into negative and positive groups according to whether theresults of EMG was normal or abnormal, PLIF surgery was performed in both groups. The preoperative duration of illness, postoperative recovery time, operative time, intraoperative blood loss, postoperative ambulation time and length of postoperative hospital stay were recorded. The clinical efficacy was evaluated by visual analogue scale(VAS) of low back and lower limb, the Japanese Orthopedic Association(JOA) score before and after operation.@*RESULTS@#All patients were follow-up from 26 to 39 months. The subjective symptoms, clinical signs, daily activities and JOA total scores after operation in two groups were significantly higher than those before preoperation(P<0.05);the clinical signs score and total JOA score in the negative group at 3 months after operation were higher than those in the positive group(P<0.05). The VAS score of leg pain in the negative group after 1 and 3 months was less than that in the positive group(P<0.05). Patients 's illness time, postoperative recovery time, hospitalization time and implantation time in the negative group were shorter than those in the positive group(P<0.05). At other time points, there was no significant difference in low pain VAS, leg pain VAS, JOA scores in the two groups(P>0.05). There was no significant difference in the operation time and intraoperative bleeding volume between the two groups(P>0.05).@*CONCLUSION@#Patients with normal electromyography had shorter disease duration than ones with abnormal electromyography in lumbar degenerative disease;after PLIF, patients with normal electromyography recovered faster than ones with abnormal electromyography, but the results of electromyography had no effect on the final prognosis of PLIF surgery.

RESUMEN

OBJECTIVE@#To investigate the effect of modified alternate negative pressure drainage on postoperative outcomes after posterior lumbar interbody fusion (PLIF) surgery.@*METHODS@#This was a prospective study involving 84 patients who underwent PLIF surgery between January 2019 and June 2020. Of these patients, 22 had single-segment surgery and 62 had two-segment surgery. Patients were grouped by surgical segment and admission sequence:the observation group included patients with a single-segment surgery, and the control group included patients with a two-segment surgery. Natural pressure drainage was given to 42 patients in the observation group (modified alternate negative pressure drainage group) after surgery, which was then changed to negative pressure drainage after 24 hours. In the control group, 42 patients were given negative pressure drainage after surgery, which was then changed to natural pressure drainage after 24 hours. The total drainage volume, drainage time, maximum body temperature at 24 hours and 1 week after surgery, and drainage-related complications were observed and compared between the two groups.@*RESULTS@#There was no significant difference in operative time and intraoperative blood loss between the two groups. The postoperative total drainage volume was significantly lower in the observation group (456.69±124.50) ml than in control group (572.36±117.75) ml, and the drainage time was significantly shorter in the observation group (4.95±1.31) days than in the control group (4.00±1.17) days. Maximum body temperature at 24 hours after surgery was similar in both groups (37.09±0.31)°C in the observation group and (37.03±0.33)°C in the control group, while on the 1st week after surgery, it was slightly higher in the observation group (37.05±0.32)°C than in the control group (36.94±0.33)°C, but the difference was not significant. There were no significant differences in drainage-related complications, with one case(2.38%) of superficial wound infection in the observation group and two cases(4.76%) in control group.@*CONCLUSION@#Modified alternate negative pressure drainage after posterior lumbar fusion can reduce the drainage volume and shorten the drainage time without increasing the risk of drainage-related complications.

RESUMEN

Objective:To investigate the relationship between the cardia morphology under magnetically controlled capsule gastroscopy and the clinical characteristics of subjects.Methods:A total of 216 subjects with gastrointestinal symptoms or receiving physical examination who underwent magnetically controlled capsule gastroscopy at the Department of Gastroenterology, Beijing Chao-Yang Hospital, Capital Medical University from August 2022 to November 2022 were enrolled. All subjects took gastroesophageal reflux disease questionnaire (Gerd-Q) survey. Clinical data of subjects were collected, and images of cardia morphology under magnetically controlled capsule gastroscopy were recorded. The subjects were divided into 4 groups according to differrent cardia morphology based on the degree of relaxation. The clinical characteristics of each group were compared, and the influencing factors for cardia morphology were analyzed.Results:In non-swallowing state, 116 subjects showed good continuous closure of the cardia in plum shape (group A), 33 subjects radial closure of cardia (group B), 46 subjects slightly relaxed linear cardia (group C) and 21 subjects relaxed and continuous opening of cardia in the shape of cave (group D). The ages of subjects in group A, B, C and D were 35.00 (31.00, 42.00) years, 53.00 (37.50, 60.50) years, 61.50 (41.50, 68.25) years and 52.00 (39.00, 70.00) years, respectively, with significant differences ( H=44.348, P<0.001). The Gerd-Q scores of subjects in group A, B, C and D were 1.50 (1.00, 2.00), 3.00 (2.00, 6.50), 8.00 (5.75, 9.00) and 8.00 (7.50, 9.00), respectively, with significant differences ( H=90.788, P<0.001). The body mass index (BMI) of subjects in group A, B, C and D were 22.66 (19.53, 24.70) kg/m 2, 23.44 (21.41, 27.05) kg/m 2, 23.77 (21.19, 26.93) kg/m 2 and 23.73 (19.63,24.79) kg/m 2, respectively, with significant differences ( H=8.114, P=0.044). The degree of cardia relaxation was positively correlated with the age ( rs=0.456, P<0.001), Gerd-Q score ( rs=0.648, P<0.001) and BMI ( rs=0.146, P=0.032) of subjects. Conclusion:The magnetically controlled capsule gastroscopy provides good visualisation of cardia morphology in non-swallowing state. There is a positive correlation between the degree of cardia relaxation under magnetically controlled capsule gastroscopy in non-swallowing state and the subjects' age, Gerd-Q score, and BMI.

RESUMEN

Objective:To explore the risk factors for lower extremity deep vein thrombosis (DVT) in patients with a spinal cord injury (SCI).Methods:The medical records of 276 hospitalized SCI patients were analyzed retrospectively. They were divided into a DVT group ( n=63) and a no-DVT group ( n=213). Gender, age, blood type, smoking history, surgical history, the time from SCI to admission, cause of SCI, fracture, SCI segments, American Spinal Cord Injury Association grade and complications were compared between the two groups. Binomial logistic regression was used to isolate the risk factors for lower extremity DVT among such patients. Results:Among 84% of the 63 with a lower extremity DVT, it was a calf muscle venous thrombosis. Anemia, hyponatremia and time from SCI to admission (which ranged from 74 to 195 days) were the most serious DVT risk factors.Conclusions:SCI patients are of high risk for DVT, with anemia and hyponatremia being independent risk factors.

RESUMEN

Objective:To evaluate the feasibility of indocyanine green fluorescence imaging technology applied in thyroid surgery to identify parathyroid gland.Methods:From Oct 2021 to May 2022, data of 42 patients undergoing thyroidectomy via gasless unilateral axillary approach in Zhejiang Provincial Hospital of Traditional Chinese Medicine were retrospectively analyzed. Cases using intraoperative fluorescence imaging technology(42 cases) were compared with conventional laparocopic approach.Results:The number of parathyroid glands dissected in the study group 1.57±0.61 was higher than that in the control group 0.56± 0.59 ( t=-5.472, P<0.05). The PTH value of the study group was (2.88±1.23)pmol/L on the first day after operation, which was higher than that of the control group (2.16±0.10)pmol/L ( t=-1.844, P<0.05). The blood parathyroid hormone value on the third day(3.22±1.31)pmol/L was higher than that of the control group (2.55±0.81) pmol/L ( t=-2.041, P<0.05). There were 2 cases of hypoparathyroidism in the study group, less than 5 cases in the control group, but there was no significant difference between the two groups( χ2=0.942, P>0.05). There was 1 case of hypocalcemia in the study group and 3 cases in the control group ( χ2=0.731, P>0.05). Conclusion:Using indocyanine green fluorescence imaging technology to identify parathyroid gland is feasible, simple, fast, safe and effective.

RESUMEN

Objective:To explore the association between body mass index (BMI) and the incidence of thyroid nodules, the clinical characteristics and efficacy evaluation of differentiated thyroid cancer (DTC), respectively.Methods:Clinical data of 1 375 healthy people (1 031 males, 344 females, age: (43.5±10.6) years) who underwent routine physical examination (PE) and 1 450 patients (490 males, 960 females, age: (44.3±12.4) years) with medium-high risk DTC in Tianjin Medical University General Hospital from April 2016 to July 2020 were analyzed retrospectively. PE and DTC patients were classified into underweight group (BMI<18.5 kg/m 2), normal weight group (18.5≤BMI<24.0 kg/m 2), overweight group (24.0≤BMI<28.0 kg/m 2) and obesity group (BMI≥28.0 kg/m 2) respectively. χ2 test was employed to analyze the relation between BMI and thyroid nodules (with/without), BMI and clinical characteristics and efficacy evaluation of DTC, respectively. Logistic regression analysis was used to analyze the independent risk factors for the occurrence of thyroid nodules and the aggressiveness of DTC. Results:Among PE, there were 779 cases with nodules, and 596 cases without nodules. Comparing with those without nodules, more overweight and obese were found in PE cases with nodules (42.1%(328/779) vs 37.2%(222/596), 24.5%(191/779) vs 20.5%(122/596); χ2=13.42, P=0.004). Higher risk of developing thyroid nodules was related with older age and lower thyroid stimulating hormone (TSH) level (odds ratio ( OR): 1.044, 0.919, 95% CI: 1.029-1.060, 0.845-0.999; P<0.001, P=0.046). People with high-risk nodules were more likely to be obese than those with intermediate and lower risk nodules (5/15 vs 24.3% (186/764); χ2=21.11, P<0.001). Among 1 450 DTC patients, comparing with patients with normal weight, patients in the overweight and obesity groups were more likely to have central regional lymph node metastasis ( OR: 1.418, 1.427, 95% CI: 1.075-1.870, 1.044-1.952; P values: 0.013, 0.026), and patients in obese group were with greater risk of lesions being bilateral ( OR=0.696, 95% CI: 0.519-0.934; P=0.016). BMI was not related with the efficacy evaluation of DTC ( χ2=9.13, P=0.425). Conclusions:The incidence of thyroid nodules in people with high BMI is higher. DTC patients with high BMI may have more aggressive incidence. But BMI has no correlation with the efficacy evaluation of DTC patients after treatment.

RESUMEN

Low back pain (LBP) is a common clinical condition, and non-specific LBP is believed to be associated with lumbar instability caused by paraspinal muscle (PSM) degeneration. Therefore, MRI evaluation of PSM degeneration can help predict the progression of low back pain-related diseases. At present, the most commonly used MRI parameters are the cross-sectional area (CSA) and fat infiltration (FI) of PSM. In order to assess the degree of PSM degeneration more accurately, modified parameters including functional CSA, relative CSA and muscle-fat infiltration index (MFI), have been designed. Advancements in MRI technology,such as the application of IDEAL-IQ, allow for early detection of changes in fat infiltration. Additionally, the proton density fat fraction (PDFF) derived from chemical shift encoding based water-fat MRI (CSE-MRI), also shows promise in studying PSM. Numerous MRI studies, both domestically and internationally, have aimed to establish the relationship between PSM degeneration and non-specific LBP, lumbar degenerative diseases, degenerative lumbar scoliosis, and osteoporosis. It has been found that PSM degeneration is affected by other factors such as intervertebral disc, articular process and endplate degeneration. Furthermore, PSM degeneration and scoliosis/kyphosis are also reciprocal causation. Higher fat content in the vertebral body and PSM is associated with increased bone fragility, while vertebroplasty following osteoporotic vertebral fracture can delay PSM degeneration and improve quality of life.

RESUMEN

Objective:To explore the application value of graded surgical strategy and balanced load concept for thoracolumbar osteoporotic compression fractures (OVCFs) with kyphosis.Methods:All of 56 patients of thoracolumbar OVCFs with kyphosis were studied, including 11 males and 45 females, with an average of 75.6±9.3 years old. All patients had back pain, and 32 patients had nerve compression, including 5 patients with aggravation of vertebral collapse after conservative treatment, and 1 patient with cement loosening after percutaneous kyphoplasty (PKP) in another hospital. A graded surgical strategy was developed according to the concept of balanced load, including whether there existed nerve compression, kyphosis, sagittal index (SI), vertebral collapse, load capacity of anterior and middle columns, and fracture reducibility. All patients were treated with anti osteoporosis therapy. 24 patients without nerve compression underwent posture reduction and PKP; 32 patients with nerve compression underwent open surgery: 5 patients with arcuate ky-phosis and SI≤15° underwent Ponte osteotomy; 15 patients with angular kyphosis or SI>15° underwent posterior pedicle subtraction osteotomy (PSO) or/and modified PSO including intervertebral space; 11 patients with SI>15° and severe vertebral collapse (the height of anterior and middle vertebral bodies <1/3 of the average height of adjacent vertebral bodies) or cement loosen after PKP underwent vertebrectomy and reconstruction, of which 4 patients underwent posterior vertebral column resection (PVCR), and 8 patients underwent combined surgery including anterior subtotal vertebrectomy with support and posterior pedicle fixation. The clinical efficacy was evaluated by pain visual analog score (VAS) and Oswestry dysfunction index (ODI).Results:All patients were followed up for 12-60 months, with an average of 24.2 months. For the 24 patients with PKP, the symptoms improved significantly, and 1 case had adjacent vertebral fracture that was improved after PKP again. For the 32 patients with open surgery, the intraoperative blood loss was 400-1 800 ml, with an average of 960 ml (PVCR > PSO and combined surgery > Ponte); the operation time was 2-7 h, with an average of 4.3±1.9 h. The neurological symptoms improved after the operation. During follow-up, the artificial vertebral body and titanium mesh collapsed in 3 cases, but did not continue to deteriorate, no vertebral fracture, internal fixation displacement or loosening failure occurred on X-ray films. At the last follow-up, the VAS score and ODI score of 56 patients decreased from 7.0±2.6 and 60.4±16.2 pre-operation to 1.4±1.1 and 9.5+5.8 respectively, and local kyphosis angle improved from 18.1±4.3 pre-operation to 5.6±4.3. According to the overall satisfaction of patients, the effect was fair in 12 cases, good in 30 cases, excellent in 14 cases, and the excellent and good rate was 78.6%.Conclusion:The graded surgical strategy for thoracolumbar OVCFs with kyphosis based on the concept of balanced load can restore the balanced load of the anterior and middle columns of the spine, reduce the fixation and fusion segments, and reduce the risk of internal fixation displacement and loosening failure.

RESUMEN

Objective:To investigate the effect of Ponte osteotomy combined with bony bridge dissection and intervertebral bone grafting in the treatment of rigid degenerative scoliosis.Methods:From March 2017 to October 2021, this method was used to treat 21 cases of rigid degenerative scoliosis, including 7 males and 14 females, aged 59-76 years, with an average age of 67.6 years. All patients had intractable low back pain and limited standing and walking, while 15 patients had radiation pain in lower limbs. The preoperative standing X-ray film showed that the average Cobb angle of lumbar scoliosis was 51.3°±24.1°, the average lumbar lordosis was 5.4°±13.6°. The coronal balance distance (CBD) was 4.3±2.0 cm (range, 0.5-6.2 cm), and the sagittal vertical axis (SVA) was 5.9±3.1 cm (range, 1.5-6.8 cm). The bending images showed huge osteophyte with bone bridge formation in the vertebral body of the apex region, with poor mobility. Ponte osteotomy was performed according to the degeneration of the deformity. The bone bridge at apex area was cut off, and the intervertebral spaces at apex area and slipped or subluxated levels were release and grafted with granular autogenous decompression bone. During follow-up, the efficacy and deformity improvement were evaluated with visual analogue scale (VAS), Oswestry disability index (ODI) and standing X-ray films.Results:All patients successfully completed the operation. The operation time was 190-330 min, with an average of 250±68 min. The intraoperative bleeding was 700-1600 ml, with an average of 970±260ml. The patients were followed up for 12-36 months, with an average of 20.6±7.2 months. No internal fixation failure, fracture or revision occurred. At the last follow-up, the VAS of low back pain decreased from preoperative 6.1±2.2 to 2.1±1.8 ( t=6.45, P<0.001), and the leg pain decreased from 5.5±3.4 to 1.2±1.0 ( t=5.56, P<0.001).ODI decreased from 52.2%±22.2% to 16.4%±10.6% ( t=6.67, P<0.001). The Cobb angle of lumbar scoliosis was 19.3°±10.5°, with an average correction rate of 62.4%; lumbar lordosis was 34.4°±15.6 °, with average correction of 30°. CBD was 1.9±1.1 cm, with an average correction of 2.4 cm ( t=4.42, P<0.001); and SVA was 1.6±2.1 cm, with an average correction of 4.3 cm ( t=4.90, P<0.001). Conclusion:Ponte osteotomy combined with bone bridge dissection and intervertebral bone grafting is an effective method to treat rigid degenerative scoliosis, which can improve spinal sequence, CBD and SVA, avoid vertebral osteotomy and reduce fusion segments.

Objective:To investigate the effect of unilateral biportal endoscopy (UBE) through extraforaminal approach in the treatment of extra canal lumbosacral nerve entrapment.Methods:Seventeen patients with extra canal lumbosacral nerve root entrapment were treated by UBE through extraforaminal approach in Tianjin Hospital from January 2020 to March 2022, including 9 males and 8 females with an average age of 59.2 years (range 45-71 years). All 17 patients had lower limb radiation pain, numbness, and weakness with or without intermittent claudication. MRI imaging examination showed L 4, 5 foramen stenosis with far lateral disc herniation in 2 case, and L 5S 1 foramen stenosis with far lateral disc herniation in 15 cases, and the height of intervertebral space decreased, resulting in the compression of exiting nerve root and ganglion. Among them, far-out syndrome was diagnosed in 7 cases and transitional lumbarsacral vertebrae was found in 12 cases. The incisions were designed 2 cm away form the projection of adjacent pedicles, while incision at S 1 was designed at the inner edge of the iliac bone due to the shielding of the ilium, taking the outer edge of the isthmus at the outer opening of the intervertebral foramen as the target of channels. The ventral and apical part of superior articular process (SAP) was gradually removed with high-speed burr from its outer edge and isthmus, and the occluded sacral ala and the lower edge of transverse process were removed when necessary. The hyperplastic ligament was removed to expose the exiting nerve root. The protruding intervertebral disc was removed at the ventral side of the nerve root. The far-out syndrome was decompressed laterally along the exiting nerve root until it is completely released. The results and stability were evaluated with visual analogue scale (VAS), Oswestry disability index (ODI), Macnab scores and dynamic X-ray film during follow-up. Results:The operation time was 45-85 min, with an average of 60 min. After remove of the SAP tip and enlarge of the intervertebral foramen, the exiting nerve root and disc protrusion were fully exposed, the exiting nerve root was exposed and released laterally until totally release without entrapment in far out syndrome, and the nerve could be decompressed completely. The symptoms were significantly relieved after operation, and imaging examination showed that facet joints were preserved. During follow-up, the pain and function improved continuously. At final follow-up, the improve rate of VAS and ODI were 85.2% and 86.2%, respectively, and the results were excellent in 15 cases and good in 2 case according to Macnab score, and there was no lumbar instability on dynamic lumbar X-ray film.Conclusion:Extra canal lumbosacral nerve entrapment can be treated by UBE through extraforaminal approach, with sufficient exposure, complete decompression and better preservation of lumbar stability.

RESUMEN

Objective:To compare the effect and biotoxicity of tert-butyl acetate (TBA) and ethyl butyrate (EB) on stone dissolution in vitro.Methods:Ten gallstone samples from patients with multiple gallbladder stones were selected and the cholesterol content was analyzed by HPLC. Stone dissolution tests of TBA and EB were performed on cholesterol gallstone in vitro, and the weight of stone at each time point was recorded, meanwhile, methyl tert-butyl ether (MTBE) was used as the control. The inhibitory effects of MTBE, TBA and EB on proliferation of human normal liver cell line LO2 were analyzed by cell proliferation inhibition assay. Flow cytometry was used to analyze the effects of MTBE, TBA and EB on the early and late apoptosis of LO2 cells, and the changes of reactive oxygen species level in LO2 cells were also analyzed.Results:Of the 10 gallbladder gallstones, 6 were cholesterol gallstones and 4 were non-cholesterol gallstones. Stone dissolution experiment showed that the remaining stones of MTBE, TBA and EB groups were (47.83±3.84)%, (58.12±4.53)% and (75.75±4.61)% 30 minutes later. The remaining stones were (18.38±6.47)%, (33.82±6.22)% and (56.38±3.91)% 90 minutes later. MTBE had the best stone dissolution effect in vitro, the stone dissolution effect of TBA was slightly weaker than MTBE, and the stone dissolution effect of EB was relatively weak in all ( P<0.05). The cell proliferation inhibition experiment showed that the cell viability of the control group, MTBE group and TBA group were (100.00±4.46)%, (96.79±4.32)% and (93.72±3.51)%, respectively, and there were no significant differences among the three groups ( P>0.05). However, the cell viability of EB group (87.57±5.29)% was lower than the above three groups, and the differences were statistically significant ( P<0.001). The early apoptosis and late apoptosis of the control group were (1.67±0.15)% and (1.27±0.06)%, respectively. EB induced early apoptosis (15.90±0.53)% ( P<0.001) and late apoptosis (5.13±0.76)% ( P<0.05). However, MTBE and TBA had no significant effect on cell apoptosis ( P>0.05). Compared with control group, MTBE, TBA and EB all significantly inhibited the level of reactive oxygen species ( P<0.05), and the inhibitory effect of EB was the most obvious. Conclusions:TBA has good stone dissolution effect and biosafety for gallbladder cholesterol stones in vitro, while EB has relatively poor performance. TBA is a potential drug for gallstone dissolution.

RESUMEN

Objective:To investigate the impact and interaction of Toll like receptor 2 (TLR2) and interferon regulatory factor 5 (IRF-5) gene polymorphisms on the susceptibility to neonatal sepsis.Methods:A total of 78 cases of neonatal septicemia patients admitted to Baoding Children′s Hospital from July 2018 to August 2021 were prospectively selected as the study group, and 78 cases of healthy newborns in the same period were selected as the control group. The TLR2 and IRF-5 gene polymorphisms and the levels of inflammatory markers [C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] in different genotypes of infants were compared between the two groups. We evaluated the relationship between TLR2 and IRF-5 genotypes, inflammatory markers, and susceptibility to neonatal sepsis, and analyzed the interaction between their gene polymorphisms and susceptibility to neonatal sepsis.Results:There were significant differences in the distribution of TLR2 (rs3804099) and IRF-5 (rs2004640) loci genotype and Allele frequency between the two groups (all P<0.05); The serum CRP, TNF-α, and IL-6 levels in children with TLR2 (rs3804099) genotype TT genotype [(111.12±30.87)mg/L, (77.50±20.02)pg/ml, (40.27±11.31)pg/ml] were higher than those in children with CC/CT genotype [(72.46±24.51)mg/L, (54.18±17.65)pg/ml, (28.34±9.05)pg/ml], and the differences were statistically significant (all P<0.05). The serum CRP, TNF-α, and IL-6 levels [(113.90±28.94)mg/L, TNF-α (79.84±19.82)pg/ml, IL-6 (41.05±11.49)pg/ml] in children with the IRF-5 (rs2004640) TT genotype were higher than those in children with the GG/GT genotype [(70.88±22.16)mg/L, (52.27±16.73)pg/ml, (27.96±9.75)pg/ml], and the differences were statistically significant (all P<0.05). The TT genotypes at TLR2 (rs3804099) and IRF-5 (rs2004640) loci were positively correlated with serum CRP, TNF-α, and IL-6 levels (all P<0.05); The TT genotypes at TLR2 (rs3804099) and IRF-5 (rs2004640) loci were independent risk factors for susceptibility to neonatal sepsis (all P<0.05); The TT genotype at the TLR2 (rs3804099) locus and the TT genotype at the IRF-5 (rs2004640) locus exhibited a positive interaction in susceptibility to neonatal sepsis ( OR=7.467, γ=1.728). Conclusions:TLR2 (rs3804099) TT genotype and IRF-5 (rs2004640) TT genotype significantly increase the susceptibility to neonatal sepsis, and there is a positive interaction between the two.

RESUMEN

Objective:To explore the characteristics of attentional bias to emotional faces of depressed college students with alexithymia.Methods:Using self-rating depression scale (SDS) and the twenty-item Toronto alexithymia scale(TAS-20), 25 low alexithymic-currently depressed undergraduates (LA-CD group), 33 low alexithymic-non depressed undergraduates(LA-ND group) and 23 high alexithymic-currently depressed undergraduates(HA-CD group) were selected from 885 valid questionnaires.Using eye tracking system, emotional face pictures were selected as stimulus materials, and the relative gaze time(attention bias score) of experimental participants was analyzed by statistical methods such as covariance analysis and adjustment analysis to explore the attentional bias of depressed college students with alexithymia.Results:(1) Under the low level of alexithymia, there was significant difference in attentional bias between college students in depression group (-0.23±0.18) and non-depressed group (0.06±0.11) ( F=55.876, P<0.01). (2) There were significant differences in relative attention bias among LA-CD group (-0.234±0.150), HA-CD group(-0.070±0.153) and LA-ND group (0.064±0.149) ( F(2, 78)=27.685, P<0.01). According to Bonferroni test, compared to the LA-CD group, the HA-CD group and LA-ND group showed less negative attentional bias.(3) The interaction between total SDS score and total TAS-20 score showed significant difference.Alexithymia played a regulatory role between total SDS score and attentional bias( β=0.333, t=3.345, P<0.01). Conclusion:Both the depressed college students with high alexithymia and the non-depressed college students with low alexithymia show less negative attentional bias.Alexithymia plays a regulatory role between depression and attentional bias.

RESUMEN

Chronic obstructive pneumonia cancer transformation refers to the malignant transformation of long-term repeated chronic inflammation of the lung. Traditional Chinese Medicine believes that the etiology and pathogenesis of chronic obstructive pneumonia cancer transformation always belong to the deficiency of origin and excess of signs. Chronic obstructive pulmonary disease causes damage to the qi of the lung, spleen and kidney. Qi is yang, and qi deficiency leads to yang deficiency. Yang deficiency and abnormal warm would result in qi stagnation, phlegm coagulation and blood stasis. It is the key to the transformation of chronic obstructive pneumonia cancer. Kidney yang is the root of yang qi. Deficiency of kidney yang is the initiating factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of lung yang is the fundamental factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of kidney yang and deficiency of spleen yang are the driving factors for the transformation of chronic obstructive pneumonia cancer. Therefore, this article discussed the role of kidney yang in the transformation of chronic obstructive pneumonia cancer from the theory of "Qi Zhu Xu Zhi", in order to broaden the thinking of clinical diagnosis and treatment of the disease.

RESUMEN

Objective:To study the evolution of Traditional Chinese Medicine (TCM) syndromes of 171 cases of Kawasaki disease (KD) under the intervention of gamma globulin therapy based on factor analysis.Methods:A cross-sectional study. 171 cases of KD children hospitalized in the Department of Cardiology of Guangzhou Women's and Children's Medical Center from July 2019 to December 2020 were collected. All patients were treated with intravenous gamma globulin (2 g/kg) for 1 week. According to the results of the treatment with C-ball, 171 children with C-ball sensitive KD were selected to collect the four diagnostic data, and the representative syndromes of defensive level, qi level, yin level, and nutritive level were observed. Factor analysis was used to analyze the evolution of syndrome in 171 children with KD c-ball sensitivity.Results:The result of factor analysis showed that the KMO statistics of 171 children with c-ball sensitivity before treatment was 0.792, and Bartley test was significant ( P<0.01). 16 common factors were extracted, and 23 syndromes were screened, mainly including defensive level disorder, qi level disorder,nutritive level disorder,yin level disorder, heat stagnation and blood stasis syndrome. One week after treatment, the statistic of KMO test was 0.787, and Bartley test was significant ( P<0.01). 9 common factors were extracted, and 10 syndromes were screened, mainly including qi deficiency syndrome, yin deficiency syndrome and blood stasis syndrome. Conclusion:Before treatment, the TCM syndromes in KD C-cell sensitive children are mainly nutritive level disorder, defensive level disorder, qi level disorder yin level disorder, and heat stagnation and blood stasis syndrome; after treatment, the main TCM syndromes are mainly qi deficiency syndrome, yin deficiency syndrome and blood stasis syndrome.
