Cystic liver metastasis, which lacks specific clinical manifestations and standardized treatment, rarely occurs after radical gastrectomy. This study presented two gastric cancer cases with cystic liver metastasis treated in Wuxi People's Hospital from September 2008 to November 2012. The two female patients were 66 and 65 years old, respectively. Poorly differentiated ulcerated adenocarcinoma classified as stage III B [Tumor, Node, and Metastasis Classification (T4aN2M0)] and clinical manifestations of abdominal distension and ascites were detected in both patients. Cyst fluids were subjected to cytological analysis. Results confirmed the presence of liver metastasis of gastric cancer. The two patients benefited from local intracavitary chemotherapy or systemic intravenous chemotherapy.

Ticks transmit various diseases to livestock and human beings. The researches on ticks are of great importance in medical and veterinary sciences. To express a glutathione peroxidase gene (HlGPx) from Hemaphysalis longicornis in Escherichia coli (E. coli) so as to provide basis for further studies, the gene was amplified from cDNAs of H. longicornis adult ticks by PCR prompted by information from EST library. The TGA codon encoding selenocysteine in the gene was mutated into the universal genetic code for cysteine,TGC, by site-directed mutagenesis. E. coli was transformed with the recombinant expression vector pGEX-4T-1/HlGPx'(the mutated HlGPx) and induced to express recombinant HlGPx', which was then analyzed by sodium dodecylsulphate-polyacrylamide gel electrophoresis and Western blotting. The result showed that the complete coding sequence of HlGPx was obtained successfully, the deduced polypeptide was 223 aa, with a calculated molecular mass of 25.0 kDa; the recombinant fusion protein was approximately 51 kDa, correspondent to the calculated. The antibody against glutathione S-transferase (GST) recognized the recombinant protein fused with GST in a Western blotting assay, which confirmed the result above-mentioned. In conclusion, the mutated HlGPx was expressed in E. coli successfully and it could be used for further preparation of immune serum and functional analysis.

Objective To study the role of emergency nursing professional team in the pre-hospital care.Methods Two hundred patients from October 2011 to March 2012 were set as the control group and another 200 patients from April 2012 to September 2012 were selected as the experiment group.The control group was managed by routine emergency mode and the experiment group by the emergency nursing professional team.The two groups were compared in terms of satisfaction degree,the time for the team to start and the rate of adverse nursing events.Results After establishing the emergency nursing professional team,the satisfaction degree was significantly increased,the time for the team to start was significantly shortened and the rate of adverse nursing events was significantly decreased(all P<0.05).Conclusion The management mode of emergency nursing professional team in pre-hospital medical care can effectively improve the quality of nursing care.

Efficacy of chemotherapy for advanced gastric cancer is unsatisfactory. Molecular targeted therapies have emerged as a novel approach to the treatment of advanced gastric cancer in recent years.These therapeutic strategies include targeting EGFR signal transduction pathway,anti-angiogenesis therapy,multi-target molecular targeted drugs. Targeted drugs such as trastuzumab,cetuximab,bevacizumab,apatinib,sorafenib sunitinib,lapatinib and everolimus which are targeting HER2,EGFR,VEGF and mTOR pathway,are applied in the comprehensive treatment of advanced gastric cancer,and their therapeutic effects are encouraging.

A cross-sectional survey on two-way referral using self-report questionnaire was conducted in a sample of 1423 residents living in 4 communities in Caobeidian area, Chaoyang District and 4 communities in Dongcheng District from April to July 2009. Among the residents who responded the questionnaire, 19.7% (88/446) from Gaobeidian and 8.2% ( 80/977 ) from Dongcheng District were referred to hospitals in 2008. And 30.7 % (27/88) in Gaobeidian and 43.8% (35/80) in Dongcheng District referred to hospital based on their own decision rather than doctors' recommendation; 45. 5% (40/ 88) in Gaobeidian and 45. 0% (36/80) in Dongcheng District of referrals were officiary processed by health institutions. The survey also showed that 57.6% and 59.4% of the respondents from the two districts preferred to free referral between community health service centers and hospitals.

Objective: To investigate the variation of γδ T cells from healthy human peripheral blood(PB)and neonatus cord blood (CB)in proliferation and subtypes with isopentenyl pyrophosphate(IPP), and to acquire enough γδ T cells possessing distinct characteristics for experimental study.Methods: Mononuclear-cells from peripheral blood and cord blood induced by IPP were stained separately with monoclonal antibodies,which were fluorescein-labeled,and then used for assaying the expressing condition of surfaco molecules,as well as to evaluate the variation of γδ T cells on the percentage, subtypes and pbenotypes by FCM.Results:γδ T cells only account for a small proportion in both PB and CB.However,there was a significant difference in the heterogeneity between peripheral blood and cord blood γδ T cells.Vγ9Vδ2 T cells were dominant in peripheral blood γδ T cells.Most of Vγ9Vδ2 T cells in fresh isolated PBMC were central memory-type(CD27~+ CD45RA~-)and effector memory-type(CD27~-CD45RA~-)with IPP, PB γδ T cells proliferated strongly;The effector memory-typo(CD27~-CD45RA~-)turned into the main subtype in all Vγ9Vδ2 T cells,and HLA-DR and B7 molecules were highly expressed on the populations.But the cord blood γδ T cells showed rather complex subgroup heterogeneity,and Vγ9Vδ2 T cells were almost na(i)ve-type(CD27~+ CD45RA~+); Though γδ T cells were expanded(the percent of γδ T cells was increased),and Vγ9Vδ2 T cells were differentiated towards central memory-type and effector memory-type on day 14 with IPP,most of γδ T celLs still remained in the phase of na(i)ve-type(CD27~+ CD45RA~+).Conclusion:Tbere lies great differences of γδ T cells in quantity and subtypes between healthy person peripheral blood and neonatus cord blood.Peripheral blood γδ T cells can be activated and proliferated with IPP, while cord blood γδ T cells have the potential to deferentiate into director memory-type which can be used for experimental and clinical study with the synergy of corresponding cytokines.The immuno-regulation and effector function will be reported in other papers.

Objective:To investigate the clinicopathological features and the prognosis of IgA nephropathy (IgAN) in children with massive proteinuria.Methods:It was a retrospective cohort study. Clinical data of IgAN children with massive proteinuria admitted to the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2008 to December 2021 were retrospectively analyzed. Patients were divided into effective group and ineffective group according to whether urine protein turned negative after 6 months of initial treatment. The follow-up endpoint event was defined as a reduction in proteinuria of less than 50% or end-stage renal disease (ESRD) achievement. MedCalc software was used to perform Kaplan-Meier survival analysis, and Log-rank test was used to compare the difference of renal survival between the two groups.Results:A total of 127 patients were diagnosed as primary IgAN by renal biopsy, of whom 57 patients with IgAN showed massive proteinuria. These 57 IgAN patients with macroproteinuria accounted for 44.9% of the total IgAN patients and were enrolled in the study. Among the 57 cases, 33 cases (57.9%) were Lee's grade Ⅲ, 11 cases (19.3%) were below Lee's grade Ⅲ, and 13 cases (22.8%) were above Lee's grade Ⅲ. The follow-up time was 4.0 (3.0,5.8) years. In the initial treatment, among 57 patients, 46 (80.7%) were effective (effective group) and 11 (19.3%) were ineffective (ineffective group). Compared with the effective group, the ineffective group had a higher proportion of concurrent AKI at the onset of disease and longer recovery time of renal function, with significant difference (7/11 vs. 13/46, χ2=4.878, P=0.027). Compared with the effective group, the proportion of Lee grade Ⅲ or above was higher in the ineffective group, and the difference was statistically significant (5/11 vs. 8/46, χ2=3.971, P=0.046). There were significant differences in endocapillary hypercellularity (E1), segmental glomerulosclerosis or adhesion (S1) and cellular/fibrocellular crescents (C2) of Oxford classification between IgAN children with Lee grade Ⅲ or below and those over Lee grade Ⅲ (11/13 vs. 20/44, χ2=6.204, P=0.013; 12/13 vs. 17/44, χ2=11.566, P=0.001; 9/13 vs. 7/44, χ2=14.131, P=0.001). Among 57 patients, endpoint events occurred in 2 patients who both were urinary protein unmitigated, and none of the children progressed to ESRD. There was no significant difference in cumulative renal survival between the two groups by Kaplan-Meier survival analysis and Log-rank test ( χ2=0.537, P=0.460) after addition of calcineurin inhibitors (CNIs) to the initial treatment ineffective group. Conclusions:Macroproteinuria is the prominent manifestation of IgAN in children. The pathological type is mainly Lee grade Ⅲ. Children with macroproteinuria have a good prognosis in the short and medium term after active treatment. For IgAN with macroproteinuria that does not respond well to initial treatment, AKI is more common at onset, and renal function recovery time is longer. The application of CNIs may have a certain effect on improving the renal outcome of IgAN with massive proteinuria.

Objective To explore the clinical features of a family with myotonic dystrophy type 1 (DM1) in order to improve the knowledge of this disease.Methods Clinical data of members from the family were collected.Electrocardiogram (ECG),electromyogram (EMG) and blood biochemistry were performed in some members of the family.Characteristics of pathology and gene of the propositi were detected.Results Anticipation was found in the family which was verified as DM1.In the all 19 patients,17 had myasthenia gravis,14 had muscle atrophy,16 had myotonia,5 had complicated with cataract,and 7 had complicated with hypophrenia.The 5 patients accepted ECG all had abnormal results,3 of them had myotonic discharge and metabolic abnormalities.Pathological analysis showed the main fibers atrophy was type Ⅰ,and the protein dystrophin expression was completely in the propositi.Conclusions The clinical manifestations of patients are various.DM1 affects eye (the lens),heart (mainly the conduction system),reproductive system besides skeletal muscle.Necessary auxiliary examinations and regular follow-up should be performed to evaluate and deal with multisystemic involvement in DM1 patients.EMG and pathological results are helpful in the diagnosis.Gene analysis can verify the disease and identify subclinical patients.

ObjectiveTo compare the efficacy and tolerability of 1-week 1％ terbinafine hydrochloride cream, 1- and 4-week 2％ miconazole nitrate cream in the treatment of interdigital tinea pedis, and to observe the relapse in patients treated with these regimens. MethodsA multi-center, randomized, double-blind and parallel group study was conducted. By using a stratified randomization protocol, patients were divided into 3 groups to apply terbinafine cream twice daily for 1 week and inert cream(placebo) for the next 3 weeks (1week terbinafine group), miconazole cream twice daily for 1 week and inert cream(placebo) for the next 3 weeks (1-week miconazole group), and miconazole cream twice daily for 4 weeks (4-week miconazole group),respectively. Clinical and mycological assessment was made on week 1, 3, 4, 6, 9 and 12 after the initiation of treatment. ResultsA total of 152 patients with positive baseline mycological culture were eligible for the efficacy analysis. After 4-week treatment, the mycological cure rates were 94.7％, 87.8％ and 82.6％, global effective rates 89.5％, 81.6％ and 63.0％, respectively for the 1-week terbinafine group, 4-week miconazole group and 1-week miconazole group. On week 12, the mycological relapse rates in 1-week terbinafine, 4-week miconazole and 1-week miconazole group were 13％, 14％ and 21％ respectively, and the incidence of adverse reaction was 2.38％, 2.38％ and 3.57％, respectively. ConclusionsAs far as the efficacy and recurrence in patients are concerned, the 1-week terbinafine cream regimen is similar to the 4-week miconazole cream regimen for the treatment of interdigital tinea pedis.
