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.

Objective:To investigate the association between the Doppler variables of the ophthalmic artery with the severity of preeclampsia(PE).Methods:Systematic literature was searched between January 1995 and March 2023 in PubMed,Web of Science,Embase,and the Cochrane Library.Studies comparing ophthalmic artery Doppler variables,including peak systolic velocity(PSV),end-diastolic velocity(EDV),resistive index(Rl),pulsa-tility index(PI),and peak ratio(PR,the ratio of the flow velocity of the second peak to that of the initial peak)in patients with PE,severe preeclampsia(sPE),and healthy pregnant women were included.The random-effects model was adopted as the method of pooled analysis,and the I2value was used to assess heterogeneity.The pooled standardized mean difference(SMD)with 95％confidence interval(CI)was used to estimate the associa-tion between ophthalmic artery Doppler variables and PE patient's characteristics.Results:Eight retrospective studies were eventually included in this Meta-analysis.Our pooled results suggested that compared with PE ca-ses,sPE patients had lower PI levels(SMD-0.56,95％CI-0.92～-0.20,P=0.000),higher EDV levels(SMD 0.47,95％CI 0.12～0.83,P=0.028)and higher PR levels(SMD0.96,95％CI 0.13～1.78,P=0.023).Howev-er,there was no significant difference between PE and sPE patients about the PSV and RI(P=0.361,P=0.626).Conclusions:This review demonstrates that ophthalmic artery Doppler variables(PI,EDV and PR)could be useful for predicting PE and PE development(especially in identifying sPE),which in turn may help the practitioner in the management of these complicated cases and in taking early necessary precautions.

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.

Objective:To explore the differences of gene expression profiles of precursors of exhausted T cells (Tpex) and terminal exhausted T cells (Tex) in the peripheral blood of patients with active pulmonary tuberculosis (ATB).Methods:Twenty-five cases of ATB, 13 cases of latent tuberculosis infection (LTBI) and 10 health controls were enrolled from January 2021 to October 2022 in the Fifth People′s Hospital of Wuxi. The proportions of Tpex and Tex in the peripheral blood mononuclear cells (PBMCs) of the three groups were detected by flowcytometry. PBMCs of ATB were separated into Tpex and Tex by fluorescence-activated cell sorting. RNA-sequencing was performed and up-regulated and down-regulated genes were screended. Differently expressed genes were analyzed by gene set enrichment analysis of gene ontology (GO) to find regulatory pathways affecting cell metabolism and function. Wilcoxon matched-pairs signed rank test, Kruskal-Wallis test and Dunn multiple comparsion test were used for statistical analysis.Results:The proportion of Tpex in ATB group was 2.86%(1.74%), which was lower than 7.93%(6.16%) of Tex, and the difference was statistically significant ( Z=-3.91, P<0.001). The proportions of Tpex and Tex in LTBI group were 9.47%(6.26%) and 7.43%(5.48%), respectively, and the difference was not statistically significant ( Z=-0.93, P=0.345). The proportions of Tpex and Tex in healthy control group were 8.42%(2.69%) and 6.49%(5.14%), respectively, with no statistical significance ( Z=-1.36, P=0.170). There was statistical difference of the proportion of Tpex among the three groups ( H=21.93, P<0.001), and the proportion of Tpex in ATB group was lower than those in LTBI and heathy control groups, and the differences were both statistically significant ( Z=4.16, P<0.001 and Z=3.34, P=0.003, respectively), while the proportions of Tex in these three groups were not statistically different ( H=2.17, P=0.338). Compared with Tex, the gene expressions of memory markers, such as B-cell lymphoma 2 of Tpex were up-regulated, and the gene expressions of exhausted markers, such as lymphocyte activation gene 3 were down-regulated. In terms of cellular metabolism, the gene expressions of mitochondrial protein complex, mitochondrial matrix and oxidative phosphorylation of Tpex were up-regulated, and the gene expressions of glycolysis were down-regulated. The gene expressions of pyruvate metabolism in Tex were up-regulated, and the gene expressions of CD4 + T lymphocyte activation and differentiation and glycolytic process in Tpex were down-regulated. Conclusions:Tpex in ATB express more characteristics of memory cells and less features of exhausted markers compared with Tex, and the function of mitochondria of Tpex preserves well.

Multiple myeloma is a malignant proliferative disease of plasma cells,and some patients may develop systemic amyloidosis.Cardiac amyloidosis is a common cause of death in these patients.Secondary adrenal insufficiency is caused by dysfunction of the hypothalamus and/or the pituitary gland,and multiple myeloma cases combined with secondary adrenal cortical dysfunction have been rarely reported in China.The patient,55-year-old,male,was admitted to the Emergency Department of Shenzhen Luohu People's Hospital on June 5,2018 due to"repeated chest tightness and fatigue for 7 months,and fainting for 1 hour".Later,he was transferred to Department of Hematology and was diagnosed as having multiple myeloma(λ light chain type)with systemic amyloidosis through bone marrow puncture and other examinations.The first course regimen of chemotherapy was bortezomib,cyclophosphamide,and dexamethasone.After the course,the patient was infected with a mixture of bacteria and fungi in the lung and had improvement after treatment.Then the regimen was adjusted to bortezomib and dexamethasone from the second course.After the fourth course,the patient achieved complete remission of multiple myeloma.After the fifth course,the patient experienced severe pulmonary-mixed infection again,which was improved after treatment.Thereafter,the patient presented with refractory hypotension,and decreased levels of cortisol and adrenocorticotropic hormone(ACTH),which was diagnosed as secondary adrenal cortical dysfunction.Hydrocortisone replacement therapy was administered.After 9 courses of chemotherapy,the patient received maintenance treatment with ixazomib.Multiple myeloma was evaluated as a stringent complete response.Cardiac amyloidosis was evaluated as a very good partial response,and secondary adrenal cortical dysfunction was treated with hydrocortisone maintenance therapy and with the cortisol level in the normal range.

Objective To duplicate the existing model of intracranial oculomotor nerve injury in rats,and propose a new method of orbital cavity clamping oculomotor nerve,evaluate the respective advantages of the two models.Methods Male SD rats were used as experimental animals,and two different methods of preparing oculomotor nerve injury models were compared.Sphenopalatine foramen approach group:clamp the initial segment of the oculomotor nerve from the opening of the upper edge of the orbit for 10 s.The skull base approach group,the temporal bone was removed and the infratentorial segment of the oculomotor nerve was clampped for 10 s.Taking the success rate,survival rate and survival status of the model rats as observation indicators,the applicability of the model rats to the intervention of gastric perfusion was and intraorbital electroacupuncture evaluated.Results The success rate after molding 24 h:In the sphenopalatine foramen approach group was 92.31%(12/13);In the skull base approach group was 34.29%(12/35).Survival rate:7 d after gavage:In the sphenopalatine foramen approach group,6 patients survived,with a survival rate of 100.00%(6/6).Four patients survived in the skull base approach group,with a survival rate of 66.67%(4/6).7 days after orbital electroacupuncture:Five patients survived in the sphenopalatine foramen approach group(83.33%,5/6).Three patients survived in the skull base approach group,with a survival rate of 50.00%(3/6).Survival state of rats(0-20 points,the smaller the score,the better):24 h after modeling,the status score of sphenopalatine foramina approach group was 4.11±0.90,and that of skull base approach group was 12.39±1.378.After 7 days of intragastric administration,the score of sphenopalatine foramina approach group was 2.50±1.05,and the score of skull base approach group was 14.50±0.58.The score of sphenopalatine foramina approach group was 2.00±1.22 and the score of skull base approach group was 15.33±0.58 after 7 days of intraorbital electroacupuncture intervention.The success rate,survival rate and survival state of rats in sphenopalatine foramina approach group were better than those in skull base approach group 24 h after modeling(P<0.05);The survival rate and survival state of rats in sphenopalatine foramina approach group were better than those in skull base approach group 7 days after gavage and orbital electroacupuncture intervention(P<0.05).Conclusion The model of oculomotor nerve injury prepared by sphenopalatine foramina approach is more suitable for the basic research of nerve repair after the intervention of gastric gavage and orbital electroacupuncture.The model rats with oculomotor nerve injury prepared by the base approach are more suitable for the basic research after the injury of the intracranial segment of the oculomotor nerve.

Chronic kidney disease（CKD）has a significant impact on global public health and is one of the important factors leading to the rise of incidence rate and mortality of non communicable diseases.Intestinal microecology is involved in many pathophysiological activities，such as immunity and nutrient absorption.With proposal of the concept of intestine-kidney axis in 2002，researchers found that the decline of glomerular filtration rate led to accumulation of uremic toxins in intestine，destroyed the intestinal mucosal barrier，led to the translocation of toxins，activated the systemic oxidative stress response，further promoted the progress of CKD.This article reviewed the function of gut microbiota，intestine-gut kidney axis，and the application of microbial preparations in CKD.

Objective:To evaluate the expressions of three biomarkers combination of CD27, CD38 and human leucocyte antigen (HLA)-DR in the application of discrminating active tuberculosis (ATB) and latent tuberculosis infection (LTBI).Methods:Sixty cases of ATB and 44 cases of LTBI were enrolled from March 2021 to February 2022 in Huashan Hospital, Fudan University and Wuxi Fifth People′s Hospital. Freshly isolated peripheral blood mononuclear cells (PBMC) from patients were stimulated with 6 kDa early secretory antigenic target/culture filtrate protein 10 peptide pools. The expressions of CD27, CD38 and HLA-DR on Mycobacterium tuberculosis-specific CD4 + T lymphocytes were evaluated by polychromatic flow cytometry. Mann-Whitney U test was used for statistical analysis. The area under the receiver operator characteristic curve (AUROC) was used to evaluate the diagnostic value of biomarkers in discriminating ATB and LTBI. Results:The frequencies of CD27 -, CD38 +, HLA-DR +, CD27 -CD38 +, CD27 -HLA-DR + and CD38 + HLA-DR + in ATB group were all higher than those in LTBI group, and the differences were all statistically significant ( U=26.00, 451.00, 384.00, 8.00, 7.00 and 184.00, respectively, all P<0.001). The AUROC of CD27 -CD4 + interferon-γ(IFN-γ) + T lymphocytes was 0.71 with a cut-off value of 52.31%, with the sensitivity of 50.00% and specificity of 87.20%. The AUROC of CD38 + CD4 + IFN-γ + T lymphocytes was 0.82 with a cut-off value of 30.25%, with the sensitivity of 73.40% and specificity of 89.70%. The AUROC of HLA-DR + CD4 + IFN-γ + T lymphocytes was 0.85 with a cut-off value of 36.60%, with the sensitivity of 66.00% and specificity of 94.90%. The AUROC of CD27 -CD38 + CD4 + IFN-γ + T lymphocytes was 0.80 with a cut-off value of 8.82%, with the sensitivity of 90.60% and specificity of 61.50%. The AUROC of CD27 -HLA-DR + CD4 + IFN-γ + T lymphocytes was 0.83 with a cut-off value of 18.62%, with the sensitivity of 75.00% and specificity of 79.50%. The AUROC of CD38 + HLA-DR + CD4 + IFN-γ + T lymphocytes was 0.93 with a cut-off value of 22.35%, with the sensitivity of 79.70% and specificity of 100.00%. Conclusions:The expressions of CD27 -, CD38 + and HLA-DR + in Mycobacterium tuberculosis-specific CD4 + T lymphocytes are higher in ATB group compared to LTBI group. ATB and LTBI could be well discriminated by detecting the expressions of CD27, CD38 and HLA-DR on CD4 + IFN-γ + T lymphocytes with flow cytometry.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
