BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50%.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21%(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

ObjectiveBased on the conjoint analysis of transcriptome and metabolome, the key genes in the phenylpropanoid biosynthesis pathway of Lonicera macranthoides were explored, which provided a basis for further exploring the synthesis and regulation mechanism of phenylpropanoid compounds in "Xianglei" L. macranthoides. MethodsThe stem, leaves, and three flowering flowers of "Xianglei" L. macranthoides were selected as experimental materials to construct transcriptome and metabolome. The transcriptome and metabolomics were conjointly analyzed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and weighted correlation network analysis (WGCNA), and the key genes in the phenylpropanoid biosynthesis pathway of L. macranthoides were explored. ResultsIn this study, 77 differential phenylpropanoids and 315 differential genes were found. Through the joint analysis of transcription and metabolism, nine key differential metabolites and four key genes related to them were finally discovered. Among them, cinnamic acid, 5-O-caffeoylshikimic acid,sinapyl alcohol, and chlorogenic acid were higher in flowers, and the content of the iconic effective component, namely chlorogenic acid,decreased sharply during the withering period. Caffeic acid,ferulic acid, 5-hydroxyconiferaldehyde,p-coumaryl alcohol, and syringin were higher in leaves. These four key genes belong to the cinnamic alcohol dehydrogenase (CAD) family, 4-coumaric acid: Coenzyme A (4CL) family, hydroxycinnamyl transferase (HCT) family, and L-phenylalanine ammonlyase (PAL) family genes. ConclusionAmong the four key genes excavated from L. macranthoides, TRINITY_DN42767_c0_g6 is related to the synthesis of p-coumaryl alcohol and sinapyl alcohol. TRINITY_DN43525_c4_g1 uses caffeic acid,ferulic acid,and cinnamic acid as substrates to catalyze the next reaction. TRINITY_DN47958_c3_g4 correlates with the synthesis of 3-p-coumaroyl quinic acid and caffeoyl-CoA, and TRINITY_DN52595_c1_g2 correlates with cinnamic acid synthesis. These findings provide a basis for further exploring the synthesis and regulation mechanism of phenylpropanoids in "Xianglei" L. macranthoides.

ObjectiveTo optimize the processing technology of honey bran-fried Rosae Laevigatae Fructus(h-RLF), formulate relevant quality standards, and explore its improving effect and mechanism on mice with ulcerative colitis(UC) induced by dextran sodium sulfate(DSS). MethodsTaking the content of polysaccharides and water-soluble extract as the indexes, L9(34) orthogonal test was used to optimize parameters of the amount of honey bran, frying time and frying temperature. The quality of 15 batches of h-RLF decoction pieces was evaluated according to the optimized process, and the inspection limit standard was preliminarily drawn up. Eighty SPF male Kunming mice were randomly divided into 8 groups, including the blank group, model group, mesalazine group(0.13 g·kg-1), RLF group(3.77 g·kg-1), bran-fried RLF group(3.77 g·kg-1), h-RLF low, medium and high dose groups(1.89, 3.77, 7.54 g·kg-1), with 10 mice in each group. The mice in the blank group were free to drink pure water, and the other groups were free to drink 3% DSS solution for 7 days to prepare UC mouse model. Each treatment group was given corresponding drugs by intragastric administration, and the blank and model groups were given equal volume of normal saline. The body weight of mice was recorded daily and the disease activity index(DAI) was calculated. After the administration, the colon tissues of mice were collected to observe the pathological changes by hematoxylin-eosin(HE) staining. The levels of tumor necrosis factor(TNF)-α, interleukin(IL)-1β, IL-6 and IL-10 in the colon of mice were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression levels of phosphorylation nuclear transcription factor-κB p65(p-NF-κB p65), Toll-like receptor 4(TLR4), p-p38 mitogen-activated protein kinase(p-p38 MAPK), p-extracellular signal-regulated kinase(p-ERK) and p-c-Jun N-terminal kinase(p-JNK) proteins in colon tissues. ResultsThe optimum processing technology of h-RLF was 20 g honey bran per 100 g RLF, and stir-frying at 200 ℃ for 8 min. The limit standard under the examination of h-RLF was preliminarily formulated as follows:the polysaccharide content should not be less than 25% based on anhydrous glucose(C6H12O6), the content of water-soluble extract should not be less than 38%, the moisture content should not be more than 12.0%, the total ash content should not be more than 5.0%, and the acid-insoluble ash content should not be more than 1.0%. The cluster heat map analysis showed that the quality of RLF from Huanggang, Hubei province was better. Animal experiments showed that compared with the blank group, the DAI score of the model group was significantly increased, the levels of TNF-α, IL-1β and IL-6 in the colon tissue were significantly increased, the IL-10 level was significantly decreased, the colonic mucosa was seriously damaged, accompanied by a large number of inflammatory cell infiltration, tissue congestion and a significant reduction in glands, and the expression levels of p-NF-κB p65, TLR4, p-p38 MAPK, p-ERK and p-JNK proteins were significantly increased(P<0.01). Compared with the model group, each administration group could alleviate the symptoms of colonic ulcer, the structure of colonic crypt was basically intact, and the glands were arranged in an orderly manner. Among them, the high-dose group of h-RLF had a better effect, which could significantly reduce the DAI score and the levels of TNF-α, IL-1β and IL-6 in colon tissue(P<0.01), and significantly increase the level of IL-10(P<0.01), alleviate the colonic mucosal injury, and effectively inhibit the expression levels of p-NF-κB p65, TLR4, p-p38 MAPK, p-ERK and p-JNK proteins(P<0.01). ConclusionThe key parameters of the processing technology of h-RLF are determined, and the optimized technology is stable and feasible. The established quality standard is simple and reliable, and can be used for the quality control. h-RLF can effectively alleviate DSS-induced UC, and its mechanism may be related to inhibiting the activation of NF-κB/TLR4/MAPK pathway.

Bisphenols (BPs) are extensively used in food packaging, personal care products, and plastics, making them prevalent in both living and working environments, which has raised significant concern. As endocrine-disrupting chemicals, BPs exert toxic effects on the female reproductive system by binding to estrogen receptors, thereby activating or inhibiting the expression of genes related to reproductive functions, which disrupts the normal function of the endocrine system. This paper reviewed the effects of bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) on female reproductive function, focusing on three key aspects: the effects on the female reproductive organs, the occurrence of associated reproductive disorders, and the mechanisms of toxicity. Specifically, this review highlighted the effects on ovarian function, uterine morphology and function, and fallopian tube function, as well as their correlation with polycystic ovary syndrome, endometriosis, miscarriage, and eclampsia. Additionally, the toxic mechanisms of BPs exposure were summarized, providing a scientific basis for future research on the impact of BPs on the female reproductive system, as well as for the assessment of potential health risks and the development of preventive measures.

Fermentum Rubrum(FR) is a kind of traditional Chinese medicine with dual-use functions of medicine and food, which has been used for more than 1 000 years. By referring to the ancient herbal classics and modern laws and regulations, the author sorted out the origin of FR, sorted out the development of processing, and analyzed the problems existing in the quality standard, aiming to provide a basis for further research and development of FR. There are many theories about the origin of FR. After summarizing and sorting out the relevant literature, three viewpoints are mainly drawn, including Han dynasty origin theory, Wei and Jin origin theory and Tang dynasty origin theory. After synthesizing the views of various schools, it is believed that the origin of FR should be no later than the Eastern Han dynasty. FR is made from rice by fermentation, which has the effect of strengthening the spleen, eliminating food, promoting blood circulation and removing stasis after fermentation. Although the natural fermentation in ancient times has been able to pay attention to the influence of temperature, humidity and strain on the quality of FR, due to the low level of science and technology, there are still problems such as complicated and cumbersome process, large workload and high labor cost. To the pure fermentation in modern times, the fermentation processing method of FR has been evolved, gradually improved and perfected. However, due to the lack of standardized research, there is no unified standard for the fermentation process of FR in various regions, and the quality standard lags behind seriously, which leads to the unstable product quality on the market. Among the 15 specifications for the preparation of FR, only 6 have been published in the past 5 years, and most of them have not been revised in a timely manner, and some of them have not been included in the updated version. Based on this, it is recommended to carry out a systematic study on processing technology of FR, and the best process is selected to accelerate the revision and improvement of its standardization, so as to improve the quality of FR sold in the market and promote its stable and sustainable development.

ObjectiveThis study aims to understand the recognition of practitioners in traditional Chinese medicine (TCM) hospitals on hospital-based health technology assessment (HB-HTA), assessment needs, challenges, and suggestions, so as to provide references for the future work. MethodThe convenient sampling method was adopted to survey the relevant practitioners in TCM hospitals. The questionnaire included 39 questions in 4 dimensions and was distributed through the online platform Weijuanxing. ResultA total of 244 questionnaires were recovered, and the obtained data were analyzed in SPSS. The results showed that 137 practitioners were very familiar with HB-HTA and there was no significant difference in the recognition of practitioners in different occupations (F=0.251; P=0.778). The practitioners in Hong Kong, Macao, and Taiwan had lower recognition than those in other regions. In terms of the assessment needs, 127 practitioners believed that it was very necessary to carry out HB-HTA in TCM hospitals in the future. Chinese patent medicines/Chinese herbal medicine decoction pieces (5.91) and TCM appropriate technology (5.57) had higher assessment priority scores. The assessment needs were high for the effectiveness (235 practitioners) and safety (224 practitioners) of health technology. The lack of specialized organization and standardized evaluation process system and the shortage of talents were considered to be the major challenges for the future development in this field. ConclusionThe stakeholders carrying out the health technology assessment in TCM hospitals had certain awareness of HB-HTA. Most practitioners believed that it was necessary to carry out HB-HTA in TCM hospitals in the future, while the work might face challenges such as the lack of organizations and system and the shortage of talents, which requires policy support.

[Objective]To identify the relationship between tumor tissue interleukins(ILs)and non-small cell lung cancer(NSCLC)patients with poor response to immune checkpoint blockade(ICB)therapy,and to investigate the differ-ential expression of ILs in tumor of NSCLC patients as well as its effect on ICB response and prognosis.[Methods]A total of 61 patients diagnosed with NSCLC and treated with ICB were retrospectively collected from the data of a previous study.We obtained transcriptome sequencing data from tumor tissues and survival data of the patients before ICB treatment.Us-ing bioinformatics methods,we screened for ILs that significantly affected the efficacy and prognosis of ICB treatment.We evaluated the efficacy of ICB treatment using progressive-free survival(PFS)and assessed the prognosis using overall sur-vival(OS).The Kaplan-Meier survival curve and ROC curve were used to analyze the predictive effect and efficacy of ILs on the efficacy and prognosis of ICB in NSCLC patients.[Results]The results of the univariate Cox regression analysis in our study showed that nine ILs were found to be associated with OS of NSCLC patients treated with ICB at a significance level of P<0.1.Further multivariate analysis revealed that high expression of IL-11,IL-17D,and IL-36A was significant-ly associated with poor prognosis in these patients(P<0.05).The results from the Kaplan-Meier survival curve analysis revealed a significant negative correlation between the high expression of IL-17D and both PFS and OS in NSCLC patients.Specifically,patients with IL-17D high expression had a median PFS of 3.1 months compared with 6.5 months in low ex-pression patients[95%confidence interval(CI)(1.178,3.655),P=0.009].Similarly,the median OS was 9.8 months in the high expression group versus 21.8 months in the low expression group[95%CI(1.116,4.392),P=0.018].ROC curve showed that the prediction performance was favorable[AUCPFS=0.702,95%CI(0.562,0.842),P=0.027;AU-COS=0.684,95%CI(0.550,0.818),P=0.014].Although IL-11 and IL-36A alone were not significant predictors of PFS and OS in NSCLC patients,the median PFS and OS were notably shortened to 2.2 months(P=0.003)and 3.0 months(P<0.001),respectively,when high expression of IL-11 and IL-36A was combined with high expression of IL-17D.The ROC curve analysis demonstrated an improvement in prediction efficiency for both PFS and OS in NSCLC patients[AUCPFS=0.748,95%CI(0.615,0.880),P=0.007;AUCOS=0.703,95%CI(0.573,0.833),P=0.007].[Conclu-sion]The results suggest that high expression of IL-11,IL-17D,and IL-36A is associated with a higher risk of disease progression which correlates to poor PFS and OS in NSCLC patients.

Objective:To explore high-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou.Methods:A cross-sectional survey was conducted in 5 different types of Guangzhou colleges by convenience sampling with minimum number of classes per grade and 600 samples per school from September to November 2021. The R 4.2.2 software was used to consolidate databases. Simultaneously, a logistic regression model and a decision tree algorithm model, stratifying by whether sexual behaviors had occurred before, were constructed. In each layer, the prediction performance of the two models was evaluated through area under receiver operating characteristic and the confusion matrix, and then the model with high prediction performance was retained.Results:A total of 7 346 students were surveyed. The proportion of the respondents reporting sexual experience were 9.08% (667/7 346), in whom 26.24% (175/667) had risky sexual activity in the past year. The decision tree algorithm model performs well in predicting whether high-risk sexual behaviors have occurred in the past year. When the complexity parameter value is 0.018, and nsplit reaches 4, which means there are 5 leaf nodes in the model, the cross error of the tree will be the smallest. The first best grouping variable in the decision tree was whether to use condoms throughout the first sexual behavior. If condoms were used at their sexual debut, but homosexual practices have occurred in the past year, the probability of risky sexual behavior will increase. If homosexual practices have not occurred in the past year, but the age of sexual debut was below 18 years old while the period of HIV education was after high school, the probability of risk sexual behavior will also increase.Conclusions:AIDS-related risky behaviors of young students still deserved attention. The experience of sexual debut and whether AIDS-related health education has been received before the sexual debut were significant predictors for the occurrence of high-risk sexual behavior. The decision tree algorithm model has particular applicability for predicting and screening potential risk populations.
