Objective To improve the diagnosis and treatment of xanthogranulomatous pyelonephri- tis(XGP).Methods The clinical data of 18 cases(5 males and 13 females;mean age,47 years)with XGP were analyzed.Of them,6 had the lesion on the left,and 12 on the right.Before operation,XGP was mis- diagnosed as renal calculus with hydronephrosis in 4 cases,ureteral calculus with severe hydronephrosis in 3 cases,renal tuberculosis in 3 cases and renal carcinoma in 8 cases.Results Of the 18 cases,7 were diag- nosed to have XGP by frozen section during operation and 11 cases had a definite diagnosis by pathological examination after nephrectomy.After a follow-up of 6-124 months,no recurrence was observed in all these 18 cases.Conclusions Preoperative diagnosis of XGP is difficult.This disease is clinically characterized by foam cells in urine smear,low-density value of kidney CT and ineffective antibiotic therapy.Combined a- nalysis of clinical data and improvement of clinical recognition of XGP is the key to avoiding delayed diagno- sis or misdiagnosis of XGP.

Objective: To explore the relationship between plasma levels of soluble receptor of advanced glycation end products (sRAGE), brain natriuretic peptide (BNP) and cardiac function in patients with sepsis.
Methods: A total of 83 sepsis patients treated in our hospital from 2014-01 to 2015-06 were studied. Plasma levels of sRAGE, BNP were examined at 24 h after admission and they were evaluated by APACHEII scores. According to BNP levels, the patients were divided into 2 groups:Normal cardiac function group, the patients with BNP<500 pg/ml, n=32 and Cardiac dysfunction group, the patients with BNP≥500 pg/ml, n=51. The cardiac function as stroke volume (SV), LVEF, minute volume, E/A were examined by echocardiography. The above indexes were analyzed and compared between 2 groups, the relationship between plasma levels of sRAGE and the occurrence of sepsis was assessed by Logistic regression analysis.
Results: Compared with Normal cardiac function group, the patients in Cardiac dysfunction group presented decreased SV, LVEF, minute volume and E/A;increased APACHEII scores and sRAGE, all P<0.01. Plasma levels of sRAGE in sepsis patients were positively related to BNP (r=0.90, P<0.05) and APACHEII scores (r=0.85, P<0.05). Logistic regression analysis indicated that plasma levels of sRAGE (OR=1.019, 95%CI 1.004-1.035, P<0.05) was independently related to cardiac function in patients with sepsis.
Conclusion: Plasma levels of sRAGE were independently related to cardiac function in patients with sepsis.

OBJECTIVETo investigate the effect of Jiangtang Yishen Recipe (JTYSR) on high insulin induced cell proliferation of human glomerular mesangial cells (HMCs) and the expression of insulin receptor substrate 1 (IRS-1) and phosphatidylinositol-3-kinase (PI-3K).

METHODSHMCs were divided into 4 groups, i.e., the negative control group, the high insulin model group, the JTYSR group, and the LY294002 group. The concentration of insulin, JTYSR, and LY294002 was respectively confirmed by pre-experiment. Different culture solution was respectively added for different groups. RPMI1640 culture solution was added for HMCs in the negative control group, while HMCs in the rest 3 groups were cultured by 100 nmol/L insulin for 24 h. Meanwhile, HMCs from the JTYSR group and the LY294002 group were exposed to 125 mg/L JTYSR and 80 micromol/L LY294002 respectively for further 48 h. The proliferation of HMCs was detected by MTT and flow cytometry. The protein expression of IRS-1 and PI-3K in HMC was detected by immunohistochemical assay and Western blot. Results The proliferation of HMCs induced by high insulin could be significantly lowered, and the protein expression of IRS-1 and PI-3K could be down-regulated in the JTYSR group and the LY294002 group (P <0.01). Compared with the LY294002 group, the protein expression of IRS-1 and PI-3K could be slightly down-regulated in the JTYSR group (P <0.05).

CONCLUSIONJTYSR could lower high insulin induced proliferation of HMCs, and its mechanism might be related to insulin signaling pathway.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

Abstract: Objective　To investigate whether the complement system of COVID-19 is affected by vaccination, and also to explore the relationship between complement and length of stay in hospital, with a view to providing input for clinical diagnosis and the management of COVID-19 patients. Methods　The patients admitted from November 1st to November 30th, 2021 in the Eighth Affiliated Hospital of Guangzhou Medical University were selected as subjects. According to the time of vaccination, the patients were divided into two groups as vaccinated within half a year and over half a year. Then C3, C4, IgG, IgM, IgA, COVID-19 IgG and IgM, neutral granulocyte and lymphocyte count were detected and all patients' hospitalized days were recorded. With their hospitalization days of 14 d as a threshold, the patients were divided into two groups, and the above indicators were compared. Results　C3 concentration was (0.86±0.157) g/L in patients with vaccination within six months, which is significantly lower than (0.96±0.172) g/L in those over six months (P<0.05), but as for C4, IgG, IgM, IgA, COVID-19 IgG and IgM, neutral granulocyte and lymphocyte counts, there were no significant difference between two groups; as for the patients within 14 days of hospitalization, C3 and C4 concentrations were lower than those for more than 14 days, but the COVID-19 antibody IgG and IgM, lymphocyte counts were higher (all P<0.05). Conclusion　Vaccination within half a year can make the body's immune function and complement system to identify viruses earlier, more beneficial to remove viruses, but this effect is weakened after half a year; when admission, C3, C4, COVID-19 IgG level and lymphocyte counts can be used to predict hospitalization time in COVID-19 patients.

Locomotor recovery and the performance of activities of daily living (ADL) of patients in two groups were assessed before and after one, two and three months training respectively, using Fugl-Meyer Assessment (FMA), Functional Independence Measure (FIM) and the scale of impairment in community rehabilitation.ResultsAfter treatment, FMA, FIM and the scale of impairment in community rehabilitation of the patients in the training group improved significantly ( P<0.001), the effectiveness was better than that of the control group ( P<0.05～0.001).The scales of FMA and FIM were proportional to the scale of impairment in community rehabilitation.ConclusionThe training technique for hemiplegia has ideal rehabilitation effectiveness.

"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.
