BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

Objective:To investigate the incidence and risk factors of coma in patients with hypoglycemia (≤3.9 mmol/L).Methods:A retrospective study was conducted. Patients aged 20 years and older with blood glucose levels ≤3.9 mmol/L, and measured by emergency physicians from January 2020 to December 2022 were collected. Baseline patient data, clinical values collected on-site, and treatment outcomes were analyzed. The Glasgow Coma Scale (GCS) was used to determine if patients were comatose, with GCS ≤8 classified as the coma group and GCS >8 as the non-coma group. Further analysis was conducted on the resuscitated coma group to identify factors affecting patient recovery. Patients were divided into eight age groups, seven time periods within 24 h, and six blood glucose level groups to calculate the incidence of coma. A multivariate logistic regression model was constructed to analyze independent risk factors for coma in hypoglycemic patients.Results:A total of 754 patients with blood glucose levels ≤3.9 mmol/L were collected, with 425 cases of coma and 329 non-coma cases, resulting in a coma probability of 56.37% (95% CI: 52.82%-59.91%). Patients in the coma group were older ( P<0.001) and had a higher prevalence of diabetes compared to the non-coma group (82.12% vs. 67.78%, P<0.001). The age of all patients was (73.05±15.20) years, with the 61-90 years age groups being the most prone to hypoglycemia and coma. In terms of time distribution, the high-incidence periods for hypoglycemia and coma were 0-6 o’clock, 6-9 o’clock, and 14-18 o’clock. The primary causes of hypoglycemia included reduced energy intake after insulin injection (12.07%), improper use of insulin (6.37%), and reduced energy intake (6.23%), with 71.09% of cases having unknown causes. Additionally, 18.44% of patients used insulin before the onset of hypoglycemia, with a higher proportion in the coma group compared to the non-coma group (22.12% vs. 13.68%, P=0.003). The initial blood glucose level of all patients was (2.13±0.85) mmol/L, with lower levels observed in the coma group compared to the non-coma group ( P<0.001). The probabilities of coma occurrence corresponding to blood glucose levels were: 1.1-1.5 mmol/L (72.97%), 1.6-2.0 mmol/L (68.90%), 2.1-2.5 mmol/L (54.10%), 2.6-3.0 mmol/L (38.20%), 3.1-3.5 mmol/L (37.50%), and 3.6-3.9 mmol/L (19.40%). Multivariate logistic regression analysis indicated that age ( OR=1.021, 95% CI: 1.010-1.033, P<0.001), insulin use before onset ( OR=1.948, 95% CI: 1.142-3.323, P=0.014), and blood glucose concentration ( OR=0.426, 95% CI: 0.347-0.522, P<0.001) were independent predictors of coma in hypoglycemic patients. The investigation revealed that after intravenous injection of 50% glucose solution, 215 of 425 coma patients regained consciousness (50.58%), and the recovery time was (18.43±9.09) min. Patients in the recovery group were younger and had lower initial blood glucose levels compared to the non-recovery group (both P<0.05), while recovery group re-measured blood glucose levels were higher than those in the non-recovery group ( P=0.002). Conclusions:The probability of coma in hypoglycemic patients was high, with insulin use being a common trigger. Proper use of insulin is essential to prevent hypoglycemia and coma.

Objective:To explore the value of the logistic regression model with three-dimensional CT quantitative parameters in combination with qualitative parameters in predicting the invasiveness of pure ground glass nodules (pGGN).Methods:The clinical data and image features of 191 patients (196 lesions) with pGGN on CT confirmed as lung adenocarcinoma by pathology from April 2019 to December 2019 in Anhui Chest Hospital were retrospectively analyzed. Totally, 196 lesions were divided into atypical adenomatous hyperplasia (AAH)+adenocarcinoma in situ (AIS)+minimally invasive adenocarcinoma (MIA) group ( n=128) and invasive adenocarcinoma (IAC) group ( n=68). CT quantitative parameters included the maximum diameter, volume, average CT value and quality of pGGN, and the qualitative parameters included the intrinsic vascular changes, abnormal air-bronchogram, lobulated signs, bubble-like sign, pleura-traction sign, and fuzzy tumor-lung interface sign. The Mann-Whitney U test was used to compare the quantitative parameters and the Pearson χ 2 test was used to compare the qualitative parameters between two groups. The independent predictors of IAC and predictive probability value were screened by univariate analysis in combination with multivariate logistic regression analysis. The ROC curves were drawn to compare the diagnostic probability of logistic regression prediction probability and each single parameter. Results:There were statistically significant differences in maximum diameter [0.92(0.77,1.14) cm vs. 1.41(1.12, 1.93) cm, Z=-7.366, P<0.001], volume[0.31(0.20, 0.53) cm 3 vs. 0.88(0.41, 2.00) cm 3, Z=-6.254, P<0.001], average CT value[-571.5(-637.2, -477.0) HU vs. -418.1(-532.4, -338.5) HU, Z=-5.882, P<0.001], quality[0.14(0.09, 0.25) g vs. 0.42(0.26, 1.21) g, Z=-7.438, P<0.001], intrinsic vascular changes(23 vs. 49, χ2=55.906, P<0.001), abnormal air-bronchogram(13 vs. 30, χ2=29.908, P<0.001) and pleura-traction sign(39 vs. 32, χ2=5.291, P=0.021) between the two groups. The logistic regression analysis showed that the maximum diameter, average CT value, intrinsic vascular changes and abnormal air-bronchogram were the independent risk factors of IAC, and the odds ratio value(95%CI) were 10.624(1.275-88.522), 1.004(1.000-1.008), 3.424(1.458-8.043) and 2.993(1.114-8.043), respectively. The ROC curve demonstrated that the area under the curve, sensitivity and specificity of the logistic regression model were 0.899, 0.912, and 0.711 respectively, which were better than separate analysis results from each single parameter. Conclusion:The logistic regression model with a combination of three-dimensional CT quantitative and qualitative parameters can predict the invasiveness of pGGN better.

Genome reannotation aims for complete and accurate characterization of gene models and thus is of critical significance for in-depth exploration of gene function. Although the availability of massive RNA-seq data provides great opportunities for gene model refinement, few efforts have been made to adopt these precious data in rice genome reannotation. Here we reannotate the rice (Oryza sativa L. ssp. japonica) genome based on integration of large-scale RNA-seq data and release a new annotation system IC4R-2.0. In general, IC4R-2.0 significantly improves the completeness of gene structure, identifies a number of novel genes, and integrates a variety of functional annota-tions. Furthermore, long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) are system-atically characterized in the rice genome. Performance evaluation shows that compared to previous annotation systems, IC4R-2.0 achieves higher integrity and quality, primarily attributable to mas-sive RNA-seq data applied in genome annotation. Consequently, we incorporate the improvedannotations into the Information Commons for Rice (IC4R), a database integrating multiple omics data of rice, and accordingly update IC4R by providing more user-friendly web interfaces and implementing a series of practical online tools. Together, the updated IC4R, which is equipped with the improved annotations, bears great promise for comparative and functional genomic studies in rice and other monocotyledonous species. The IC4R-2.0 annotation system and related resources are freely accessible at http://ic4r.org/.
