Objective:To understand the incidence rate of herpes zoster (HZ) and postherpetic neuralgia (PHN) in Beijing, and analyze the incidence trend of HZ and PHN from 2015 to 2022.Methods:Cases of HZ and PHN from 2015 to 2022 were retrieved from the Hospital Information Systems (HIS) of all primary and above hospitals/clinics in three districts representing the urban, inner suburban, and outer suburban areas of Beijing. After duplication screening, the first visit cases were screened, and the incidence characteristics were described. The incidence rate of HZ and PHN in each year by sex and age group and the age-standardized incidence rate were calculated. The annual percentage increase (APC) of incidence rate was calculated using the Joint regression model, and the change trend was analyzed.Results:The age-standardized incidence rate of HZ in Beijing from 2015 to 2022 ranged from 7.44‰ to 10.05‰, with an average annual incidence rate of 8.95 ‰, significantly increasing with age ( P<0.001). The Joinpoint regression model showed that the overall age-standardized incidence of HZ remained relatively stable, with no significant difference (APC=2.28%, t=1.56, P=0.170). However, the incidence rate among the 0-19-year-old group exhibited a trend of decrease (APC=-10.70%, t=-6.29, P<0.001). For PHN, the age-standardized incidence in Beijing ranged from 0.77‰ to 2.67‰, with an average annual incidence rate of 1.59‰ and a proportion of 9.48% to 26.86% among HZ cases. Both the incidence of PHN and its proportion among HZ cases increased with age ( P<0.001). The age-standardized incidence of PHN increased annually (APC=18.56%, t=9.02, P<0.001). Conclusion:The incidence rate of HZ and PHN in Beijing continues to be at a high level, and PHN shows an increasing trend over time.

[Objective]To summarize Professor SHEN Minhe's clinical experience in treating tumors under the guidance of the therapeutic concept of"heart governs as sovereign,medicine acts as general and diet functions as minister".[Methods]By studying with the teacher,sorting out and summarizing Professor SHEN Minhe's clinical tumor cases,this paper expounds in detail the unique treatment concept of"heart governs as sovereign,medicine acts as general and diet functions as minister",and verifies it with medical records.[Results]Professor SHEN Minhe thinks that the treatment of tumor should pay attention to the organic combination of mind,medicine and food.Heart governs as sovereign means:emphasizing the compatibility between doctors and patients,attaching importance to spirit,and coordinating form and mind;Medicine acts as general:emphasizing chronic diseases,keeping the body safe from evil,eliminating evil at the right time,and adding and subtracting herbs with the syndrome;Diet functions as minister:emphasizing that if diet is self-doubling,stomach will be injured,reasonable diet and three-factor adaptation are suitable.The attached medical record was a case with lung cancer,which was mainly caused by stagnation of liver-Qi and phlegm.The case was treated by soothing the liver and clearing heat,reconciling Shaoyang,resolving phlegm and dredging collaterals,regulating Qi and dredging Fu-organs,calming the heart and the nerves,with revised Chaihu and Longgu Muli Decoction,Little Chaihu Decoction and Weijing Decoction,and instructed to eat and live regularly,adjust breathing and standing as stake in the morning,and follow the way of healthy preservation,finally the patient returned to balance,with good effect.[Conclusion]Professor SHEN treats tumors with the concept of"heart governs as sovereign,medicine acts as general and diet functions as minister",which has remarkable curative effect and certain clinical guiding significance.

Objective To investigate the feasibility of estimating the real-ear-to-coupler difference(RECD)in children with head circumference,so as to further optimize the personalized and accurate matching scheme of hearing aid fitting for children.Methods A total of 106 children(197 ears)were enrolled in this study.Head circumference was measured using a soft ruler and RECD was measured using OmetroricsAuricalTM.SPSS software was used to analyze the correlation between the head circumference,month age and RECD values at each frequency of children.Results ① The head circumference of boys was slightly larger than that of girls,but there was no significant differ-ence between them(P＞0.05).② Unitary linear correlation analysis showed that RECD values at 750-6 000 Hz were negatively correlated with the head circumference,and a regression equation was established between RECD values at 1 000-6 000 Hz and the head circumference.③ RECD values calculated by regression formula based on the head circumference showed no significant difference between 1 000-3 000 Hz and 6 000 Hz and children's actu-al RECD values.Conclusion The individual RECD values of 0-6 years old children were correlated with the head circumference,and with the increase of the head circumference,RECD values at middle and high frequencies de-creased gradually.For children whose physical developments were not consistent with biological age,the RECD data at middle and high frequencies could be estimated based on the head circumference.

Objective:Super-enhancer-associated genes may be closely related to the progression of osteosarcoma,curcumin exhibits a certain inhibitory effect on tumors such as osteosarcoma.This study aims to investigate the effects of curcumin on osteosarcoma in vitro and in vivo,and to determine whether curcumin can inhibit the progression of osteosarcoma by suppressing the expression of super-enhancer-associated genes LIM and senescent cell antigen-like-containing domain 1(LIMS1),secreted protein acidic and rich in cysteine(SPARC),and sterile alpha motif domain containing 4A(SAMD4A). Methods:Human osteosarcoma cell lines(MG63 cells or U2OS cells)were treated with 5 to 50 μmol/L curcumin for 24,48,and 72 hours,followed by the methyl thiazolyl tetrazolium(MTT)assay to detect cell viability.Cells were incubated with dimethyl sulfoxide(DMSO)or curcumin(2.5,5.0 μmol/L)for 7 days,and a colony formation assay was used to measure in vitro cell proliferation.After treatment with DMSO or curcumin(10,15 μmol/L),a scratch healing assay and a transwell migration assay were performed to evaluate cell migration ability.Real-time reverse transcription polymerase chain reaction(real-time RT-PCR)and Western blotting were used to detect mRNA and protein expression levels of LIMS1,SPARC,and SAMD4A in the cells.An osteosarcoma-bearing nude mouse model was established,and curcumin was administered via gavage for 14 days to assess the impact of curcumin on tumor volume and weight in vivo.Real-time RT-PCR was used to measure mRNA expression levels of LIMS1,SPARC,and SAMD4A in the cancer and adjacent tissues from 12 osteosarcoma patients. Results:After treating cells with different concentrations of curcumin for 24,48,and 72 hours,cell viability were all significantly decreased.Compared with the DMSO group,the colony formation rates in the 2.5 μmol/L and 5.0 μmol/L curcumin groups significantly declined(both P＜0.01).The scratch healing assay showed that,compared with the DMSO group,the migration rates of cells in the 10 μmol/L and 15 μmol/L curcumin groups were significantly reduced.The exception was the 10 μmol/L curcumin group at 24 h,where the migration rate of U2OS cells did not show a statistically significant difference(P＞0.05),while all other differences were statistically significant(P＜0.01 or P＜0.001).The transwell migration assay results showed that the number of migrating cells in the 10 μmol/L and 15 μmol/L curcumin groups was significantly lower than that in the DMSO group(both P＜0.001).In the in vivo tumor-bearing mouse experiment,the curcumin group showed a reduction in tumor mass(P＜0.01)and a significant reduction in tumor volume(P＜0.001)compared with the control group.Compared with the DMSO group,the mRNA expression levels of LIMS1,SPARC,and SAMD4A in the 10 μmol/L and 15 μmol/L curcumin groups were significantly down-regulated(all P＜0.05).Additionally,the protein expression level of LIMS1 in U2OS cells in the 10 μmol/L curcumin group was significantly lower than that in the DMSO group(P＜0.05).Compared with adjacent tissues,the mRNA expression level of SPARC in osteosarcoma tissues was significantly increased(P＜0.00l),while the mRNA expression levels of LIMS1 and SAMD4A did not show statistically significant differences(both P＞0.05). Conclusion:Curcumin inhibits the proliferation and migration of osteosarcoma both in vitro and in vivo,which may be associated with the inactivation of super-enhancer-associated gene LIMS1.

Objective To explore the effect of chlorophyll derivative on wound healing after hemorrhoidectomy. Methods A total of 124 patients with circular hemorrhoids after procedure for prolapse and hemorrhoids (PPH) were selected and divided into control group and experimental group. The granulation formation time, wound healing time, degree of wound edema and pain before and after treatment, serum biochemical indicators, adverse reactions and complications were compared between two groups. Results The granulation formation time and wound healing time in the experimental group were significantly shorter than those in the control group (P < 0.05). After treatment, wound edema score and pain score as well as serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in both groups were significantly lower than those before treatment, and these indexes after treatment in the experimental group were significantly lower than those in the control group (P < 0.05), but the differences of the above indexes before and after treatment in the experimental group were significantly higher than those in the control group (P < 0.05). After treatment, the levels of serum epidermal growth factor (EGF), fibronectin (FN) and basic fibroblast factor (bFGF) in both groups increased significantly, and these indexes after treatment in the experimental group were significantly higher than those in the control group (P < 0.05). Conclusion Chlorophyll derivative can promote granulation formation and wound healing after hemorrhoidectomy, and reduce degrees of edema and pain.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To observe the expression changes of microRNA(miR)-122 in liver tissue of rats infected with Clonorchis sinensis and its correlation with expression level of inflammatory cytokines. Methods:Totally 24 SPF grade Wistar male rats were selected and randomly divided into a control group (100 μl physiological saline gavage), a 4-week infection group (100 Clonorchis sinensis metacercariae gavage), and an 8-week infection group (100 Clonorchis sinensis metacercariae gavage) based on body weight (100-120 g) using a random number table method, with 8 rats in each group. Starting from the third week of infection, rat feces were collected and directly smeared with physiological saline for identification of Wistar rat animal models infected with Clonorchis sinensis. After 4 and 8 weeks of infection, the rats in the 4- and 8-week infection groups were euthanized, while 4 rats in the control group were euthanized, respectively. The heart blood and left lobe liver tissue and serum samples were collected from each group of rats. Using hematoxylin-eosin (HE) staining to observe liver pathological damage under the light microscope, real-time fluorescence quantitative PCR to detect the expression level of miR-122 in liver tissue, and Luminex 200 liquid suspension chip to detect the expression levels of serum inflammatory cytokines [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6 (IL-6)]. The correlation between miR-122 and inflammatory cytokines was analyzed using Pearson correlation. Results:Under the light microscope, the morphology of hepatocytes in control group was normal, and no inflammatory cell infiltration was observed. There was inflammatory cells such as lymphocyte, eosinophil and other inflammatory cell infiltration around the portal area in the 4-week infection group. The hepatocytes of the 8-week infected rats were arranged in a disordered manner, with varying degrees of swelling, loose and lightly stained cytoplasm, and some hepatocytes showed watery degeneration; additionally, bile duct dilation and thickening of the bile duct wall were observed in the liver tissue. There were statistically significant differences of liver miR-122 (1.00 ± 0.32, 2.57 ± 0.60, 3.63 ± 1.63), serum TNF-α [(0.14 ± 0.06), (0.43 ± 0.09), (0.61 ± 0.10) ng/ml], and IL-6 expression levels [(0.03 ± 0.01), (1.06 ± 0.24), (1.48 ± 0.33) ng/ml] in control group, 4- and 8-week infection groups ( F = 13.36, 69.99, 82.23, P < 0.001). There was no statistically significant difference in expression level of IL-1β between different groups ( F = 2.15, P = 0.141). The Pearson correlation analysis showed that the expression level of miR-122 was positively correlated with the expression levels of inflammatory cytokines TNF-α and IL-6 ( r = 0.67, 0.80, P < 0.001). Conclusion:Clonorchis sinensis infection can increase the expression of miR-122 in the host liver tissue, and the miR-122 is closely related to the expression levels of inflammatory cytokines TNF-α and IL-6.
