Objective To observe the effect of Danzhi Jiangtang Capsules(DJC) on serum interleukin-18 (IL-18),cystatin C (CysC) and relative biochemical indexes in patients with early diabetic kidney disease(DKD),and to explore its protective action on the kidney.Methods Sixty-two hospitalized patients with early diabetic nephropathy (period 11-Ⅲ) in Endocrinology Department of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine were divided into western medicine group and DJC group,31 cases in each group.The patients in western medicine group received conventional hypoglycemic drugs,and DJC group received DJC based on the treatment for the western medicine group.Before and after treatment,we observed the levels of serum IL-18,CysC,fasting plasma glucose (FPG),2-hour postprandial glucose (2hPG),glycosylated hemoglobin (HbA1c),serum creatinine (SCr),blood urea nitrogen (BUN),microalbumin (mAlb),urinary albumin /creatinine ratio (UACR),and estimated glomerular filtration rate (eGFR).Results The total effective rate was 90.0％ in DJC group and 76.7％ in the western medicine group,there being significant difference between the two groups(P ＜ 0.05).After treatment,the main traditional Chinese medical syndrome scores of DJC group were significantly lower than those before treatment,and the improvement was better than that of the western medicine group (P ＜ 0.05 or P ＜ 0.01).After treatment,the serum levels of IL-18,CysC,2hPG,SCr,BUN,mAlb,UACR in the two groups were significantly lower than those before treatment (P ＜ 0.05 or P ＜ 0.01),while eGFR level was higher than that before treatment (P ＜ 0.05 or P ＜ 0.01),and the improvement effect (except for BUN) in the DJC group was superior to that in the western medicine group(P ＜ 0.01).DJC had an effect on lowering the FPG and HbA1c (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment),and the western medicine had no obvious effect on the two indexes (P ＞ 0.05).The results of Spearman correlation analysis showed that IL-18 was correlated with CysC,IL-18 and CysC were correlated with HbA1c,mALB and uACR.Conclusion DJC can protect renal function of patients with early diabetic nephropathy.

This study chiefly aimed at investigating the effects of Dan Zhi Jiang Tang Capsule (DJC) on myocardial Toll-like receptor 4 (TLR4),tumor necrosis factor α (TNFα) and interleukin-8 (IL-8) and the cardiopathologic changes in diabetic rats.Fifty male rats,excluding 8 rats in the control group,had been administered with high fat forage for 4 weeks,which established the diabetic rat model combined with the intraperitoneal injection of streptozotocin (STZ) at 35 mg· kg-1.The established model rats were randomly divided into the model group,the DJC high-dose group,the DJC low-dose group and the pioglitazone group.The rats in the model group and the control group were intragastrically administered with DJC at 1.08 and 0.54 g· kg-1 each day,while those of the pioglitazone group were treated with pioglitazone at 10 mg· kg-1 each day,and those of the model group and control group with saline of the same volume.The administrations lasted 8 weeks with the continues high-fat diet.The levels of TLR4,TNFα and IL-8 protein in myocardium of the rats were determined,and so were the blood glucose,HbA1c and blood lipids.Compared with the control group,the expressions of myocardial TLR4,TNFα and IL-8 in the model group were significantly increased (P＜ 0.01).The expressions of TLR4,TNFα and IL-8 in the DJC high-dose and low-dose groups were significantly decreased (P＜0.05 or P＜0.01).The cardiopathological report showed severe myocardial lesion in the model group.However,myocardial lesion in the DJC high-dose group was significantly mitigated,which presented better therapeutic effects than the DJC low-dose group and the pioglitazone group.The levels of blood glucose,HbA1c,TG,TC,LDL-C in the model group were significantly higher than those in the control group (P＜0.05 or P＜0.01).The levels of blood glucose,HbA1c,TG,TC and LDL-C were significantly decreased in the DJC high-dose and low-dose groups in comparison with the model group (P＜ 0.05 or P＜ 0.01).In conclusion,DJC down-regulated the expressions of TLR4,TNFα and IL-8 and improved the degree of myocardial lesion in the diabetic rats,showing favorable hypoglycemic and lipid-lowering effects.

Objective To evaluate the relationship between the concentration of pentane in the exhaled air and degree of the lung injury in non-heart-beating (NHB) rabbits.Methods Twenty-four healthy male Japanese white rabbits weighing 2.4-3.0 kg were randomly divided into 4 groups ( n =6 each):A,B,C and D groups.The NHB model was established by exsanguination through the femoral artery.The exhaled gases were collected and lung tissues were removed at 0,30,60 and 120 min after cardiac arrest in A,B,C and D groups respectively.The concentration of pentane in the exhaled gases was detected immediately using the gas chromatography-mass spectrography.The wet to dry (W/D) lung weight ratio and content of malondialdehyde (MDA) in lung tissues were measured.The lung injury score (LIS) was recorded.The maximal volume ( Vmax ) of the lung was recorded when the airway pressure reached 30 cm H2O.Results Compared with groups A and B,the exhaled pentane concentration was significantly increased in group C,and the W/D ratio,content of MDA and LIS were significantly increased,while Vmax was significantly decreased in group D ( P ＜ 0.05).Compared with group C,W/D ratio and LIS were significantly increased in group D ( P ＜ 0.05 ).Conclusion The concentration of exhaled pentane can not reflect the degree of the lung injury in NHB rabbits.

Objective An experiment study on the femoral head plastic operation to prevent and treat aseptic necrosis of the femoral head. Methods 60 Chinese white rabbits were equally random divided into 4 groups. The four groups except A group were made a globose defect and filled with 95% alcohol tampon for 30 minutes. The B group was natural repair group. The C group was filled with bone cement after being made defect. The D group was filled with bone cement added barium sulfate agent after being made defect. After 12 weeks, all rabbits in four groups were killed. The specimens were random divided into two parts. The articular cartilage was observed and measured immediately. The other specimen was determined with histological examination and extreme anti-pressure rigidity test . Result The femoral heads of bone cement group and the femoral heads of contrast agent bone cement group kept their outline all the time through the articular cartilage observation. After 12 weeks the cartilage thickness of natural repair group (511.74 ± 69.00) was thinner than the other three groups [ control group ( A group ) (511.74 ± 69 00 );Bone cement group ( C group) (468. 36 ± 82. 99 ); Bone cement group contrast agent ( D group ) ( 515.61 ±64. 65 ) ], and it had significant difference ( P < 0. 05, P < 0. 01 ). The rigidity of natural repair group [ (676. 57 ±50. 92) N/mm] had significant difference with that of the other three groups[ A group( 884. 66±52. 29)N/mm;C group(1178.40 ± 170.45) N/mm;D group(928.60 ± 104.42) N/mm] ( P <0.05, P<0. 01 ). Conclusions Femoral head plastic operation was simple and it could release pain. And femoral head outline could be kept integrity. It would be a new operation which was used to treat young patients in Ficat Ⅱ～Ⅲ period to postpone or substitute total hip replacement.

OBJECTIVETo investigate the characteristics,diagnosis and therapy of post-biopsy renal artery pseudoaneurysm in children and to study the clinical value of arterial embolization for traumatic renal hemorrhage when conservative treatment failed.

METHODData were compiled from medical records of a child in whom renal artery pseudoaneurysm occurred after biopsy in the Provincial Hospital Affiliated to Shandong University , and the related literature was reviewed to analyze the diagnosis and treatment of such pseudoaneurysm.

RESULTA 13-year-old boy had gross hematuria, aggravated dysuria and decreased hemoglobin 10 days after percutaneous renal biopsy. Hb decreased from 110 g/L on the first day after admission to 92 g/L on the 4th day, 83 g/L on the 7th day and the minimum to 74 g/L at the 8th day after admission. Ultrasound showed solid echogenic mass in the right renal pelvis as well as the bladder. Color Doppler ultrasound shows the red and blue rotation of blood flow in the polar capsule under the right kidney. Contrast-enhanced CT in the arterial phase showed a 0.5 cm sized renal mass with a strongly enhanced dot in the lower pole of the right kidney, suggesting a renal artery pseudoaneurysm. Haemostatic, supplement of red blood cells and blood volume and other integrative treatment of hematuria were applied for seven days, but his gross hematuria continued to be worsened. He was diagnosed as pseudoaneurysm by digital subtraction angiography (DSA) on the 19th day after renal biopsy. Superselective renal artery embolization using micro-coils and gelatin sponge particles was performed, and the blood clots were cleaned under cystoscope. Macro-haematuria and dysuria disappeared after the interventional treatment. Retrieval of reports on post-biopsy renal artery pseudoaneurysm in children by using "pseudoaneurysm, child" as the search term showed report of one case from the Chinese CNKI database and 3 cases from the PubMed database. The underlying disease was Henoch-Schonlein purpura nephritis in 3 cases and Sneedon syndrome in 1 case; clinical manifestation of gross haematuria was present in 4 cases, lumbago or pain at the site of the puncture in 2 cases, dysuria in 1 case, and fever in 2 cases.

CONCLUSIONThe post-biopsy renal artery pseudoaneurysm in children is often manifested as gross hematuria, lumbago, pain at the site of the puncture, fever and dysuria, DSA can be used for definite diagnosis and the interventional treatment is effective.

Objective:To explore the cortical abnormalities in brain regions in adolescent with self-injury and the correlation between cortical structural changes and clinical emotional manifestations.Methods:From April 2023 to June 2024, totally 38 adolescents with self-injury(self-injury group) from psychological outpatient department of First People’s Hospital of Changzhou and 41 healthy volunteers (HC group) matched with age, gender and years of education were selected.T1-weighted magnetic resonance imaging and clinical data of all participants were collected. All of them were investigated by the 17-item Hamilton depression scale (HAMD-17) and Hamilton anxiety scale (HAMA). Image preprocessing and surface-based morphometry analysis were performed by the DPABISurf software. Cortical parameters from regions showing significant differences were extracted, which were then evaluated the correlation with the emotional scores based on Spearman correlation analysis by SPSS 29.0 software.Results:Compared with HC group, self-injury group showed reduced thickness in areas primarily involving the left somatosensory and motor cortex, left paracentral lobular and mid cingulate cortex, left posterior cingulate cortex and premotor cortex(MNI: cluster 1: x=-17.73, y=-32.81, z=43.87, cluster 2: x=-35.97, y=-8.72, z=52.01, cluster 3: x=-18.94, y=-41.39, z=65.94)(all P<0.05). Lower sulcal depth in the left orbital and polar frontal cortex (MNI: x=-39.9, y=47.92, z=-5.42) ( P<0.05) and higher mean curvature in the right superior parietal cortex (MNI: x=21.89, y=-61.89, z=50.55) ( P<0.05) were found in the self-injury group. In the self-injury group, Spearman correlation analysis revealed negative correlations between cortical thickness in the regions of interest and clinical emotional scores (HAMD-17: r=-0.385, -0.332, P<0.05; HAMA: r=-0.395, -0.481, P<0.05), primarily involving the left supplementary motor area, left premotor cortex and the left somatosensory and motor cortex. Conclusion:The perception and execution cortex of adolescents with self-injury shows surface morphological abnormalities, which may be relevant to clinical emotional manifestations.

Objective To investigate the therapeutic effect and prognostic significance of lateral lymph node dissection (LPLND) in patients with lateral lymph node (LPLN) metastasis. Methods The clinicopathological data of rectal cancer patients who underwent total mesorectal excision (TME) combined with LPLND and pathologically confirmed as LPLN metastasis after operation were retrospectively analyzed. The clinicopathological characteristics and metastasis rules of patients with LPLN metastasis were discussed, and the survival prognosis after LPLND was analyzed. Results A total of 102 rectal cancer patients with pathologically confirmed LPLN metastasis were included. The common sites of LPLN metastasis were internal iliac vessels lymph nodes (n=68, 66.7%), followed by obturator lymph nodes (n=44, 43.1%), and common iliac vessels or external iliac vessels lymph nodes (n=12, 11.8%). There were 10 patients (9.8%) with bilateral LPLN metastases, and the mean number of LPLN metastases was 2.2±2.4, among which 16 patients (15.7%) had LPLN metastases number≥2. The 3-year OS (66.8% vs. 7.7%, P < 0.001) and DFS (39.1% vs. 10.5%, P=0.012) of patients with LPLN metastases to the external iliac or common iliac lymph node were significantly lower than those with metastases to the internal iliac or obturator lymph node. The multivariate analysis showed that LPLN metastasis to external iliac or common iliac lymph node was an independent risk factor both for OS (HR=3.53; 95%CI: 1.50-8.31; P=0.004) and DFS (HR=2.40; 95%CI: 1.05-5.47; P=0.037). Conclusion LPLN mainly metastasizes to the internal iliac or obturator lymph node areas. The survival of patients with metastasis to the external iliac or common iliac lymph node cannot be improved by LPLND, and thus systemic comprehensive treatment is often the optimal treatment option.

Objective:To evaluate the immunogenicity, safety, and immune persistence of the sequential booster with the recombinant protein-based COVID-19 vaccine (CHO cell) in healthy people aged 18-84 years.Methods:An open-label, multi-center trial was conducted in October 2021. The eligible healthy individuals, aged 18-84 years who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, were recruited from Shangyu district of Shaoxing and Kaihua county of Quzhou, Zhejiang province. All participants were divided into three groups based on the differences in prime-boost intervals: Group A (3-4 months), Group B (5-6 months) and Group C (7-9 months), with 320 persons per group. All participants received the recombinant COVID-19 vaccine (CHO cell). Blood samples were collected before the vaccination and after receiving the booster at 14 days, 30 days, and 180 days for analysis of GMTs, antibody positivity rates, and seroconversion rates. All adverse events were collected within one month and serious adverse events were collected within six months. The incidences of adverse reactions were analyzed after the booster.Results:The age of 960 participants was (52.3±11.5) years old, and 47.4% were males (455). The GMTs of Groups B and C were 65.26 (54.51-78.12) and 60.97 (50.61-73.45) at 14 days after the booster, both higher than Group A′s 44.79 (36.94-54.30) ( P value<0.05). The GMTs of Groups B and C were 23.95 (20.18-28.42) and 27.98 (23.45-33.39) at 30 days after the booster, both higher than Group A′s 15.71 (13.24-18.63) ( P value <0.05). At 14 days after the booster, the antibody positivity rates in Groups A, B, and C were 91.69% (276/301), 94.38% (302/320), and 93.95% (295/314), respectively. The seroconversion rates in the three groups were 90.37% (272/301), 93.75% (300/320), and 93.31% (293/314), respectively. There was no significant difference among these rates in the three groups (all P values >0.05). At 30 days after the booster, antibody positivity rates in Groups A, B, and C were 79.60% (238/299), 87.74% (279/318), and 90.48% (285/315), respectively. The seroconversion rates in the three groups were 76.92% (230/299), 85.85% (273/318), and 88.25% (278/315), respectively. There was a significant difference among these rates in the three groups (all P values <0.001). During the sequential booster immunization, the incidence of adverse events in 960 participants was 15.31% (147/960), with rates of about 14.38% (46/320), 17.50% (56/320), and 14.06% (45/320) in Groups A, B, and C, respectively. The incidence of adverse reactions was 8.02% (77/960), with rates of about 7.50% (24/320), 6.88% (22/320), and 9.69% (31/320) in Groups A, B, and C, respectively. No serious adverse events related to the booster were reported. Conclusion:Healthy individuals aged 18-84 years, who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, have good immunogenicity and safety profiles following the sequential booster with the recombinant COVID-19 vaccine (CHO cell).
