This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C （SSC） on acute liver injury （ALI） in mice induced by carbon tetrachloride （CCl4） based on serum metabolomics. METHODS Forty mice were divided into blank group （water）， model group （water）， positive control drug group （Biphenyl diester drop pills， 150 mg/kg）， and SSC low- and high-dose groups （2.5， 10 mg/kg） using the random number table method， with 8 mice in each group. They were given water/ relevant drugs， once a day， for 7 consecutive days. One hour after the last administration， all mice were intraperitoneally injected with 0.2% CCl4 olive oil to induce ALI model， except for the blank group. After 17 hours of the modeling， the liver index of mice was calculated. The levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， lactate dehydrogenase （LDH）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and IL-1β in serum of mice were detected. The histopathological changes of liver tissue were observed. Meanwhile， the serum metabolomics of mice were analyzed by liquid chromatography-mass spectrometry. RESULTS Compared with the blank group， the levels of liver index， ALT， AST， LDH， TNF-α， IL-6， and IL-1β in the model group were significantly increased （P＜0.01）. Hepatocytes were edema， vacuolar degeneration， more necrosis， and a large number of inflammatory cells were infiltrated. Compared with the model group， liver index and serum index levels of mice were significantly decreased （P＜0.05 or P＜0.01）， accompanied by marked improvement in histopathological damage to the liver tissue. The metabolomics results showed that compared with the model group， there were 63 up-regulated and 256 down-regulated differential metabolites in the serum of mice in the SSC high-dose group， including prostaglandin B2， 20-hydroxy-leukotriene B4， 5- hydroxy-L-tryptophan， 7α -hydroxycholesterol， etc.； these metabolites were primarily involved in metabolic pathways such as arachidonic acid metabolism， 5-hydroxytryptamine synapse， primary bile acid biosynthesis. CONCLUSIONS SSC exerts a protective effect against CCl4-induced ALI by down-regulating the level of key metabolites such as prostaglandin B2 and 20-hydroxy-leukotriene B4， and then ruducing metabolic pathways such as arachidonic acid metabolism， 5- hydroxytryptamine synapse， and primary bile acid biosynthesis.

Objective To investigate the association between dipstick hematuria and chronic kidney disease(CKD)in patients with diabetes mellitus(DM).Methods DM patients who underwent the first health examination among the working and retired employees of Kailuan General Hospital and 11 affiliated hospitals in Tangshan City,Hebei Province from 2006 to 2007 were included as the study objects.Test dipstick hematuria is defined by the level of urine occult blood on the test paper:negative dipstick hematuria(NH)<10 erythrocytes/μl,moderate dipstick hematuria(MH)trace～1+(10～49 erythrocytes/μl),severe dipstick hematuria(SH)2+～3+(≥50 erythrocytes/μl).CKD is diagnosed based on eGFR and urinary protein levels.Logistic regression model was used to analyze the association between paper hematuria and CKD in DM patients.Results A total of 8958 DM patients were included,including 2390 patients(26.68%)in the CKD group and 6568 patients(73.32%)in the DM group.The detection rates of moderate dipstick hematuria and severe dipstick hematuria in CKD group were 9.00%and 4.64%,respectively,higher than those in DM group(7.20%and 2.33%).The risk of CKD in MH and SH patients was 1.560(95%CI 1.260～1.940)and 3.080(95%CI 2.220～4.270)times that in NH patients,respectively.The odds ratios were 1.960(95%CI 1.530～2.510)and 3.430(95%CI 2.270～5.200)in males and 0.910(95%CI 0.580～1.430)and 2.760(95%CI 1.570～4.880)in females.The odds ratios were 1.650(95%CI 1.150～2.350)and 4.070(95%CI 2.240～7.400)in patients aged≥60 years,and 1.550(95%CI 1.170～2.040)and 2.860(95%CI 1.920～4.240)in patients aged<60 years.Conclusions Dipstick hematuria is a risk factor for CKD in DM patients.The association between dipstick hematuria and CKD in DM patients is not only independent of traditional risk factors,but also affected by age and gender.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Alzheimer's disease is a common central neurodegenerative disease， mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear， and the western medicine currently used to treat Alzheimer's disease is only symptomatic， with a single pathway， limited efficacy， and many side effects. In recent years， with the deepening of research on Alzheimer's disease， the study and application of traditional Chinese medicine （TCM） in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation， oxidative stress， neuroinflammation， ferroptosis， mitochondrial dysfunction， neurogenesis and neurotransmission， and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years， so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

Objective To explore the expression level of visceral adipose tissue-derived serine protease inhibitor(Vaspin)and secreted frizzled-related protein5(SFRP5)in the serum of children with idiopathic short stature(ISS)and its diagnostic value.Methods 70 children with ISS diagnosed in the First Hospital of Zhangjiakou from December 2021 to February 2023 were selected as the disease group,while 72 healthy volunteer children who underwent physical examination were collected as the control group.Immunoluminescence was applied to detect the expression level of VASPIN,Enzyme-linked immunosorbent assay(ELISA)was applied to detect the expression level of SFRP5 the clinical data of children in two groups were analyzed.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum Vaspin and SFRP5 for ISS,multivariate Logistic regression was used to analyze the influencing factors of ISS.Results Compared with the control group,the serum Vaspin level in the disease group was obviously increased(2.89±0.92 ng/ml vs 1.81±0.42 ng/ml),while the SFRP5 level was obviously reduced(10.22±2.84 pg/ml vs 13.21±3.53 pg/ml),the differences were statistically significant(t=9.040,5.552,all P＜0.05).The weight,height,body mass index(BMI)and proportion of sexual development stage II～V of children in the disease group were obviously lower than those in the control group,and the differences were statistically significant(t=7.687,6.330,5.559,7.024,all P＜0.05).The area under ROC curve showed that the AUC of Vaspin and SFRP5 and their combined detection in the diagnosis of ISS were 0.768,0.849 and 0.925,respectively,the combined diagnosis efficacy of Vaspin and SFRP5 was better than that of serum Vaspin and SFRP5 alone(Z =3.829,P＜0.001;Z =2.141,P=0.032).Multivariate Logistic regression analysis showed that BMI(OR=0.508,95%CI:0.260～0.991),Vaspin(OR=3.458,95%CI:1.125～10.631)and SFRP5(OR=0.378,95%CI:0.153～0.935)were the influencing factors for ISS(all P＜0.05).Conclusion The expression level of Vaspin in the serum of children with ISS is obviously increased,while the expression level of SFRP5 is obviously reduced.The two are influencing factors of ISS,and the combined detection of their expression levels has certain value in the diagnosis of ISS.

Objective:To explore the clinical effectiveness of a self-designed robot reduction system for femoral intertrochanteric fractures.Methods:A retrospective study was conducted to analyze the 57 patients with intertrochanteric fracture who had been treated at Department of Orthopedics, The Fourth Affiliated Central Hospital of Tianjin Medical University from June 2022 to February 2023. The patients were divided into a robot group (using the self-designed robot reduction system to assist intramedullary nailing) and a traction bed group (using a traction bed to assist intramedullary nailing) based on their fracture reduction method. The robot group: 31 patients, 11 males and 20 females, with an age of (78.7±9.3) years; 16 left and 15 right sides; 17 cases of type 31-A1, 12 cases of type 31-A2 and 2 cases of type 31-A3 by the AO/OTA classification. The traction bed group: 26 patients, 12 males and 14 females, with an age of (78.7±7.7) years; 13 left and 13 right sides; 16 cases of type 31-A1, 9 cases of type 31-A2 and 1 cases of type 31-A3 by the AO/OTA classification. The 2 groups were compared in terms of reduction and operation time, intraoperative blood loss, fluoroscopy frequency, reduction quality, and VAS and Harris score at preoperation, 1 week and 6 months postoperation.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data ( P>0.05). The robot group was significantly better than the traction bed group in reduction time [(4.4±2.2) min versus (9.4±3.2) min], operation time [(29.0±13.5) min versus (49.3±13.3) min], intraoperative blood loss [(76.5±30.5) mL versus (115.0±38.4) mL], fluoroscopy frequency [(10.2±2.6) times versus (14.8±3.2) times], and good/excellent rate of reduction [80.6% (25/31) versus 50.0% (13/26)] ( P<0.05). All patients were followed up for (6.8±0.3) months. Respectively, the VAS scores at preoperation and 6 months postoperation was (6.2±1.3) and (2.4±0.8) points for the robot group, and (6.3±1.3) and (2.7±0.8) points for the traction bed group, showing no statistically significant differences between the 2 groups ( P>0.05). However, the VAS score was (3.3±1.2) points for the robotic group and (4.8±1.5) points for the traction bed group at 1 week postoperation, showing a statistically significant difference between the 2 groups ( P<0.001). Respectively, the Harris scores at preoperation and 6 months postoperation were (35.3±3.0) and (88.7±3.4) points for the robot group, and (35.6±2.9) and (87.2±3.5) points for the traction bed group, showing no statistically significant differences between the 2 groups ( P>0.05). However, the Harris score was (57.3±3.7) points for the robotic group and (46.7±2.8) points for the traction bed group at 1 week postoperation, showing a statistically significant difference between the 2 groups ( P<0.05). The patient satisfaction rates in the robot and traction bed groups were 96.8% (30/31) and 92.3% (24/26), respectively, showing no statistically significant difference ( P>0.05). Conclusion:Our self-designed robot reduction for femoral intertrochanteric fractures can effectively shorten reduction and operation time, reduce bleeding and fluoroscopy frequency, and enhance anatomical reduction.

Objective:To assess the safety and feasibility of selectively preserving the first branch of the right gastro-omental artery using bidirectional dissection in laparoscopic pylorus-preserving gastrectomy (LPPG).Methods:In this retrospective analysis, we studied preoperative, intraoperative, postoperative, and follow-up data of 30 patients with early gastric cancer treated in the Department of Gastric Cancer in Zhejiang Cancer Hospital (28 patients), Department of Gastrointestinal Surgery in Jiaxing Second Hospital (one patient) and Department of Gastrointestinal Surgery in Hangzhou Red Cross Hospital (one patient) who had undergone selective preservation of the first branch of the right gastro-omental artery during LPPG. The main variables studied were as follows: (1) intraoperative preservation of the first branch of the right gastro-omental artery; (2) the overall surgical situation; and (3) postoperative small bowel follow-through and endoscopy findings.Results:LPPG with selective preservation of the right gastro-omental artery vascular branch was achieved in all 30 of the study patients. The mean operation time was (244.3±29.3) minutes and the median intraoperative blood loss 50 (20–200) mL. The median tumor diameter was 1.2 (0.5–3.6) cm and an average of 32.3±11.6 lymph nodes were dissected. The overall median number of positive lymph nodes was 0 (0–6), and of No. 6 lymph nodes 5.1±1.5. Postoperative feeding resumed at an average of 5.2±0.5 days and the postoperative hospital stay averaged 8.4±3.4 days. Pathological stages were as follows: T1a (14 cases), T1b (10 cases), and T2 (6 cases). Small bowel follow-through imaging showed good results in 28 patients 5 days post-surgery, the remaining two exhibiting good results 9 days post-surgery. There were no instances of delayed gastric emptying, and only one patient (3.3%) developed intra-abdominal infection (resolved with conservative treatment).Conclusion:Selective preservation of the right gastro-omental artery during laparoscopic early gastric cancer surgery is a safe and feasible procedure for treating early mid-gastric body cancer with pyloric preservation.
