Guided by the theory of latent pathogens， it is believed that the basic pathogenesis of adult-onset Still's disease is the latent pathogens in the deep yin level. The onset of the disease is fundamentally characterized by the deficiency of both qi and yin as the root， with dampness， heat， phlegm， and blood stasis as the branch， which triggered by intruding pathogens activate the latent pathogens in yin level. The treatment focuses on nourishing yin and dispersing heat as the key therapeutic method. It is proposed that clearing and resolving dampness-heat， expelling pathogens outward， dispersing the latent pathogens， reinforcing healthy qi and consolidating the root， boosting qi and nourishing yin as treatment idea. In clinic， Qinghao Biejia Decoction （青蒿鳖甲汤） could be used as the basic formula， and modified with characteristic herb pairs such as Qinghao （Artemisia annua） - Digupi （Lycium chinense） to enrich yin and clear heat， and enforce the power of clearing deficient heat； Biejia （Lawsonia inermis） - Xuchangqing （Vincetoxicum mukdenense） to enrich yin and activate blood， unblock the collaterals and dissipate masses； Duhuo （Angelica biserrata） - Mudanpi （Paeonia × suffruticosa） to dispel wind and activate blood， resolve dampness and unblock the collaterals， so as to clear and warm simultaneously， and regulate qi and blood at the same time； and Chuanshanlong （Dioscorea nipponica） - Difuzi （Bassia scoparia） to dissolve stasis and dispel phlegm， explore and dispel latent pathogens.

Objective:To investigate the morbidity of cerebrovascular disease among residents ≥30 years in Pengzhou, Sichuan Province, and analyze the effect of physical activity level on the risk of morbidity of cerebrovascular disease.Methods:From 2004 to 2008, people from Pengzhou, Sichuan Province were randomly selected. All the local people aged 30-79 were asked to receive a questionnaire survey, physical examination, and long-term follow-up to determine the morbidity of cerebrovascular disease. The physical activity level and the morbidity of cerebrovascular disease were described, and Cox proportional hazard regression models were used to evaluate the association of domain-specific physical activity with the risk of morbidity of cerebrovascular disease.Results:In 55 126 participants, there were 5 290 new cases of cerebrovascular disease, with a cumulative incidence of 9.60%. After the adjustment for multiple confounding factors, multivariate Cox proportional hazard regression analysis showed that increased levels of occupational, transportation, and total physical activity reduced the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). The highest group of occupational physical activity level had the lowest risk of cerebrovascular disease, with a hazard ratio ( HR) value of 0.81 (95% CI: 0.75-0.88), the highest group of transportation physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.84 (95% CI: 0.78-0.91), the highest group of total physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.87 (95% CI: 0.80-0.94), compared with the lowest group of corresponding physical activity. No association was found between the household/leisure-time physical activity level and the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Conclusions:In project areas of Pengzhou, Sichuan Province, increased physical activity has been associated with reduced morbidity of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Increased levels of physical activity in adults are encouraged for health benefits.

Objective:To study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

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 explore the clinical value of serum protein kinase N1(PKN1),tumor necrosis factor receptor superfamily member 4(TNFRSF4),and DNA damage-inducible transcription factor 4(DDIT4)in predicting lymph node metastasis and prognosis of patients with endometrial cancer.Methods A total of 180 cases of endometrial cancer patients treated in Tangshan Maternal and Child Health Hospital from October 2019 to October 2021 were selected as endometrial cancer group.In addition,180 patients with benign uterine diseases treated in this hospital during the same period were selected as the benign disease group,and 180 healthy patients who underwent physical examination in this hospital were selected as the healthy group.The endometrial cancer group was divided into 42 cases with lymph node metastasis and 138 cases without lymph node metastasis according to whether lymph node metastasis occurred.The patients were divided into poor prognosis group and good prognosis group according to the follow-up results.The levels of serum PKN1,TNFRSF4 and DD1T4 in each group were compared,the influencing factors of patient prognosis were analyzed by Logistic model,and the predictive value of serum PKN1,TNFRSF4 and DDIT4 on prognosis of patients was analyzed by drawing the receiver operating characteristic curve.Results Compared with the healthy group,the levels of serum PKN1 and DDIT4 in endometrial cancer group and benign disease group were in-creased,and the levels of serum TNFRSF4 were decreased,with statistical significance(P＜0.05).The serum levels of PKN1 and DDIT4 in lymph node metastasis group were higher than those in no lymph node metasta-sis group,and the levels of TNFRSF4 were lower than those in no lymph node metastasis group,with statisti-cal significance(P＜0.05).The proportion of poor prognosis group with low differentiation degree,positive lymphovascular space invasion and myometrial infiltration≥1/2 was higher than that of good prognosis group,and the difference was statistically significant(P＜0.05).The levels of serum PKN1 and DDIT4 in the poor prognosis group were higher than those in the good prognosis group,and the levels of TNFRSF4 were lower than those in the good prognosis group,with statistical significance(P＜0.05).Serum PKN1,DDIT4,LVSI and myometrial infiltration were risk factors for the prognosis of endometrial cancer,and serum TN-FRSF4 was protective factor for the prognosis of endometrial cancer(P＜0.05).Serum PKN1,TNFRSF4 and DDIT4 combined predicted the prognosis of patients with endometrial cancer more effectively than each serum index alone(P＜0.05).Conclusion Serum PKN1,TNFRSF4 and DDIT4 are related to lymph node metasta-sis and prognosis of patients with endometrial cancer,and have high predictive efficacy for patient prognosis.

Sepsis is a life-threatening organ dysfunction caused by the imbalance of host immune response to infection,which immune regulation mechanism is complex and has not been clarified.Programmed death receptor-1(PD-1)/programmed death recep-tor ligand-1(PD-L1)is a negative co-inhibitory molecule that has attracted much attention in recent years.Studies have shown that PD-1/PD-L1 signaling pathway plays an important immunosuppressive role in sepsis.There are differences in immune regulation mecha-nisms in heart,liver,spleen,lung and kidney,which has not been clarified.Immune regulation of PD-1/PD-L1 in different organs of sepsis is reviewied in this article,which could to provide a new direction for the study of sepsis.

Objective:To investigate the expression of soluble T cell immunoglobulin and mucin domain-3 (Tim-3) in peripheral blood of patients with pancreatic cancer and its diagnostic value in combination with serum Carbohydrate antigen 19-9 (CA19-9) .Methods:106 newly diagnosed pancreatic cancer patients and 65 age and sex matched healthy individuals were enrolled. Tim-3 concentration was quantitatively determined by enzyme-linked immunosorbent assay (ELISA). According to the expression levels of soluble Tim-3 and serum CA19-9, a binary logistic regression model of receiver operating characteristic (ROC) curve was established to compare the diagnostic effects of serum CA19-9 and soluble Tim-3 alone or combined with the two tests.Results:The levels of soluble Tim-3 in the pancreatic cancer group were significantly higher than those in the healthy control group ( P<0.001). The expression level of soluble Tim-3 was significantly higher in patients with stage III-IV pancreatic cancer than in patients with stage I-II ( P=0.003). The AUC of soluble Tim-3 diagnosis for stage I-II pancreatic cancer was 0.856 (95%CI: 0.765 to 0.992 P<0.001), Serum CA19-9 The AUC used for the stage I-II pancreatic cancer diagnosis was 0.862 (95%CI: 0.772 to 0.926 P<0.001), The AUC for the combined diagnosis was 0.949 (95%CI: 0.880 - 0.985 P<0.001) ; In a healthy population and in patients with stage III-IV pancreatic cancer, the AUC of soluble T I I-IV pancreatic cancer in stage III was 0.927 (95%CI: 0.873 to 0.963 P<0.001), the AUC of serum CA19-9 used for the diagnosis of stage III-IV pancreatic cancer was 0.933 (95%CI: 0.881 to 0.968 P<0.001), the AUC for the combined diagnosis was 0.989 (95%CI: 0.956 to 0.999 P<0.001) . Conclusions:The combination of soluble Tim-3 and serum CA19-9 can improve the diagnostic rate of pancreatic cancer patients.

【Objective】 To analyze ABO system hemolytic disease of the fetus and newborn (HDFN) and its influencing factors in Obstetrics Department of our hospital. 【Methods】 The blood samples of 1 040 neonates and their mothers in the obstetric department of our hospital were retrospectively analyzed from September 2022 to January 2023, including ABO and RhD blood group of the neonates and mothers, as well as 3 tests of HDFN, Hb, total bilirubin (TBIL) and indirect bilirubin(IBIL) of the neonates. Relevant clinical data of the neonates and mothers were collected, including maternal and neonatal age, neonatal sex, maternal pregnancy history, gestational age and delivery mode, and their influences on ABO-HDFN were analyzed. 【Results】 Among 1 040 HDFN samples, 298 were ABO incompatibility, among which 113 were HDFN positive, with a positive rate of 37.9% (113/298); the positive rate of HDFN in neonates born to mothers with type O was significantly higher than that in neonates born to mothers with type A and B (71.4% vs 8.2%, P<0.05); the positive rate of HDFN in neonates with antigen-A incompatibility was significantly higher than that in neonates with antigen-B incompatibility (48.7%vs 26.7%, P<0.05), which was the highest in neonates with O-A incompatibility [83.6% (61/73)], followed by O-B incompatibility [58.2% (39/67)]. There was no significant difference in Hb and bilirubin among the other groups except for the difference of Hb between the O-A incompatibility HDFN positive group and the HDFN negative group [(145.0±16.0) vs(153.4±13.2), P<0.05)]. The levels of Hb, TBIL and IBIL in the "direct antiglobulin test+ indirect antiglobulin test+release test+" group were significantly different from those in the HDFN negative group[(144.9±21.6) vs (153.3±13.2), P <0.05; (36.9±11.8) vs (29.6±6.1), P<0.05; (30.6±12.7) vs (23.0±6.9), P<0.05, respectively]. Logistic regression analysis showed that maternal delivery frequency, mother-neonate incompatible antigen and maternal blood type were independent risk factors for HDFN. 【Conclusion】 ABO-HDFN occurred mainly in neonates born to O-type mothers, and the positive rate was the highest in neonates with O-A incompatibility. The severity of HDFN had little relationship with the mother-neonate blood type, but had relationship with the result of 3 tests of HDFN. Maternal delivery frequency, mother-neonate incompatible antigen and maternal blood type were independent risk factors for HDFN.

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.
