Objective To observe the clinical efficacy ofZhibai Dihuang Decoction combined with endocrine therapy for kidney-yin deficiency type of advanced prostate cancer and its influence on patient symptoms of hot flashes.Methods Totally 72 cases of advanced prostate cancer patients were randomly divided into the combined group (36 cases) and the control group (36 cases). Patients in the control group were treated with endocrine therapy, while patients in the combined group were additionally treated byZhibai Dihuang Decoction. After 12 weeks of treatment, serum prostate specific antigen (PSA), the international prostate symptom score (I-PSS), the clinical symptoms score, the number of cases of hot flashes and safety index before and after treatment were observed. Results In the course of treatment, the control group and the combined group each had 1 case lost to follow up. PSA and I-PSS in the two groups significantly decreased after treatment (P<0.01). The total efficiency rate of TCM syndrome was 94.3% (33/35) in the combined group, while it was 57.1% (20/35) in the control group, with significant difference (P<0.01). After treatment, the incidence of hot flushes was reduced after treatment in the combined group, but the control group increased, with significant difference (P<0.01). No adverse reaction was found in the two groups.ConclusionZhibai Dihuang Decoction combined with endocrine therapy is more effective than endocrine therapy alone, which can reduce the symptoms of hot flashes.

ObjectiveTo investigate the prevention and treatment of pneumonia in patients with acute cervical spinal cord injury (CSCI).MethodsData of 278 patients with acute traumatic CSCI admitted from 1988 to 2004 were analyzed retrospectively.Results Pneumonia was the major complication following acute CSCI and discovered by radiography during the first 3—33 days after injury. The all cases were nosocomial pneumonia and G- bacilli were main pathogens, particularly pseudomonas aeruginosa. The incidence of pneumonia of patients with score ≤6 according to the criteria of American Spinal Injury Association (ASIA) was significantly higher than those with ASIA score >6 (P<0.001).ConclusionThe high incidence of pneumonia in the CSCI is associated with the level and completeness of the injury. The G- bacilli causing nosocomial infection are main pathogens.

OBJECTIVETo explore the molecule mechanism of Salidroside inducing directional differentiation of mouse mesenchymal stem cells (MSCs) into neuronal cells.

METHODSThe mouse multipotent mesenchymal precursor cell line (D1) was taken as the objective. Cultured MSCs were divided into the negative control group (complete culture solution), the positive control group (containing 1 mmol/L β-mercaptoethanol), the Salidroside induced group (20 mg/L Salidroside), and the blocked group (20 ng/ ml DKK1, a special inhibitor of Wnt/β-catenin signal pathway). All cells were inoculated in a 6-well plate (1 x 10(4) cells/cm2) and grouped for 24 h. The expression of p-catenin was detected by fluorescence Immunochemistry in the negative control group, the positive control group, and the Salidroside induced group. The expression of neuron-specific enolase (NSE), beta 3 class III tubulin (β-tubulin III), nuclear receptor related factor 1 (Nurr1), glial fibrillary acidic protein (GFAP) mRNA, Wnt3a, β-catenin, low-density lipoprotein receptor-related protein6 (LRP6), Axin mRNA were detected using reverse transcrip- tion PCR (RT-PCR). The expression of β-catenin and NSE protein were analyzed by Western blot in the negative control group, the positive control group, and the Salidroside induced group. Ca2+ chelating agents (EGTA), L-type Ca2+ channel blocker (Nifedpine), and IP3Ks special inhibitor (LY294002) were used to block Ca2+ signal pathway respectively. The expression of Wnt3a, LRP-6, Axin, glycogen syn- thase kinase (GSK-3), and β-catenin mRNA were detected by RT-PCR. The β-catenin protein expression was analyzed using Western blot.

RESULTSCompared with the positive control group, β-catenin protein was strong positively expressed; the expression of Wnt3a, β-catenin, LRP6, Axin, NSE, β-tubulin III, Nurr1 mRNA, and NSE protein were obviously up-regulated in the Salidroside induced group (P < 0.01). Compared with the positive control group and the Salidroside induced group, β-catenin, NSE, Nurr1, and β-tubulin III mRNA expression decreased; β-catenin and NSE protein expression were also down-regulated in the blocked group (P < 0.01). Compared with the Salidroside induced group, the expression of Wnt3a, LRP-6, β-catenin, and Axin mRNA were down-regulated in the Ca2+ signal blocked group and the salidroside induced group (P < 0.01, P < 0.05).

CONCLUSIONSalidroside affected directional differentia- tion of MSCs into neuronal cells through Wnt/β-catenin and Ca2+ signal pathway.

Abstract: Objective　To investigate the clinical manifestations, diagnosis, treatment and prognosis of COVID-19-associated multisystem inflammatory syndrome in children (MIS-C) with multisystem organ failure, and to analyze the differences between the syndrome resembling Kawasaki disease and Kawasaki disease. Methods We report a case of child diagnosed with SARS-CoV-2 infection who developed MIS-C with multi-organ failure. Literature was reviewed to further discuss clinical symptoms, diagnosis, treatment, and prognosis of MIS-C. Results The patient 's condition progressed rapidly and was severe, with acute kidney injury at admission, presenting with urine output of 0 mL in 8 hours, serum creatinine of 675.1 μmol/L, urea nitrogen of 38.2 mmol/L, creatine kinase 4 932 U/L, along with continuously elevated serum amylase, peaking at 5 809.7 U/L, aspartate aminotransferase of 995 U/L, alanine aminotransferase of 240 U/L, and frequent vomiting. The patient was categorized as critically ill. The confirmed patient with MIS-C was managed in pediatric intensive care units (PICU), received early continuous blood purification, jejunal tube feeding, and combined treatment with intravenous methylprednisolone pulse and human immunoglobulin for intravenous injection (IVIG), resulting in complete recovery and discharge. Through literature review, it can be analyzed that MIS-C is systemic inflammatory response characterized by multi-organ dysfunction from a cytokine storm, which differentiates it from Kawasaki disease characterized by acute systemic vasculitis triggered by infectious factors, ultimately leading to cardiovascular accidents as the main cause of death.Conclusions When fever (≥38 ℃) persists for at least 24 hours, accompanied by high inflammatory symptoms and dysfunction in two or more systems, requiring intensive care treatment, and there is evidence of SARS-CoV-2 infection, MIS-C should be diagnosed early, and intervention and treatment should be initiated promptly to achieve favorable outcomes.
