Objective:To study on the target antibody composition,the titer,and immune cross reaction of immunoglobulin products.Methods:ELISA kit for IgG antibody against varicella zoster virus,cytomegalovirus,herpes simplex Ⅰ and Ⅱ type virus,rabies virus,tetanus toxoid and IgG RIA kit specific to hepatitis virus surface antigen were utilized.The antibody titer of 5 kinds of specific immunoglobulin,and the IgG injection for either intramuscular or intravenous preparations was detected.Results:There were higher antibody titer against rabies,HBsAg and tetanus in the immunoglobulin preparations,probably due to the blood donors immunized with correspording vaccination.Compared with the antibody preparations of higher efficacy against cytomegalovicrus dotained by screening,there was a narrow disparity for the titer of the target antibody in the blood IgG preparations.In the population,also widespread existence for infection by varicella zoster virus and herpes simplex Ⅰtype virus,the antibody titer level was lower than those against cytomegalovirus,higher than herpes simplex Ⅱtype virus.Conclusion:All of the 7 kinds target antibody can be detected from the samples of immunoglobulin,antibody titer is related with active and passive immunity,higher titer of against cytomegalovirus can be induced by vaccine of varicella zoster virus,there is noticeable difference for antibody titer level between the intramuscular and intravenous injection immunoglobulin.

OBJECTlVE To study the effect of ganoderma poIysaccharide( GLP)on zebrafish ( Danio rerio)survivaI,deveIopment and senescence. METHODS A p53-knockout zebrafish modeI was estabIished by injecting of morphoIino phosphorodiamidate(mO)into normaI zebrafish eggs in the singIe ceII deveIopment stage. Different concentrations of GLP 1,2 and 3 g·L-1 were used to treat both wiId type and p53-knockout zebrafish embryos 8 h post fertiIization(8 hpf)under 28℃ for 3 d. The survivaI and maIformation rates were caIcuIated after 72 hpf,and the effect of GLP on ceII senescence was evaI-uated by senescence associated β-gaIactosidase(SA-β-gaI)staining both in wiId type and p53-knockout zebrafish embryos. In addition,the differentiaI gene expression of cancer inhibitor gene(p53),teIomer-ase reverse transcriptase( TERT),murine doubIe minute2( mdm2)and p21 was examined by RT-PCR both in wiId type and p53-knockout zebrafish embryos after treatment with different concentrations of GLP. RESULTS GLP 1 and 2 g·L-1 had no effect on deveIopment of wiId type zebrafish embryos,but after GLP 3 g·L-1 treatment,most of zebrafish embryos dispIayed maIformation and the survivaI rate was onIy 48.6%. GLP 1,2 and 3 g·L-1 had no effect on survivaI and deveIopment of p53-knockout zebrafish embryos. After GLP 2 g·L-1 treatment for 3 d,the SA-β-gaI staining positive rate of wiId type zebrafish embryos was reduced compared with controI group(P﹤0.01),whiIe there was no significant change in p53-knockout zebrafish embryos. The resuIts of RT-PCR showed that GLP 2 g·L-1 treatment depressed p21 and p53 gene expression(P﹤0.05,P﹤0.01),and had no effect on mdm2 and TERTgene expres-sion of wiId type zebrafish embryos. For p53-knockout zebrafish embryos,the TERT,mdm2,p21 and p53 gene expression dispIayed no significant difference after GLP 2 g·L-1 treatment. CONCLUSlON GLP 2 g·L-1 may improve senescence of wiId type zebrafish embryo ceIIs. GLP ≥3 g·L-1 may Iead to death and abnormaI deveIopment of wiId type zebrafish embryos. The improvement of GLP on senescence of wiId type zebrafish embryo ceIIs might be mediated by its down-reguIation of p21 and p53 gene expression.

Objective To evaluate the technical feasibility and clinical efficacy of retroperitoneal and transperitoneal laparoscopic nephrectomy for nonfunctional kidney with giant hydronephrosis. Methods The clinical data of retroperitoneal group (26 patients) and transperitoneal group (23 patients) who underwent laparoscopic nephrectomy for nonfunctional kidney with giant hydronephrosis were analyzed retrospectively. Compared with operating time,kidney size, blood loss, postoperative intestinal function recovery time, postoperative hospital stay and operative efficacy of the two groups. Results All the operations were performed successfully. Operating time,kidney size and blood loss were not significantly different between two groups(P＞ 0.05). While in retroperitoneal group, postoperative intestinal function recovery time and postoperative hospital stay were significantly reduced than those in transperitoneal group [( 18.0 ± 1.2)h vs. (48.0 ±2.0) h, (5.5± 1.6) d vs. (7.5 ± 1.6) d](P＜0.05). All patients were followed up 1 -3months,no abnormal. Conclusions The retroperitoneal and transperitoneal laparoscopic nephrectomy for nonfunctional kidney with giant hydronephrosis can be performed efficiently and effectively. Retroperitoneal laparoscopic is better than transperitoneal laparoscopic on postoperative recovery aspects.

Objective To explore the technique and effect of selected three-field lymphadenectomy by left thoracotomy in treatment of thoracic middle or lower section esophageal squamous carcinoma. Methods From Jun. 2005 to Mar. 2009, 213 patients with thoracic middle or lower section of esophageal carcinoma received esophagectomy, bilateral mediastinal lymphadenectomy and pleural membrane resection.Group 1 -5, 7 - 12a, 16al, and 19 were performed to dissect abdominal lymph node and extended thoracic and abdominal lymphadenectomy and only lymph node extraction of mesoesophagus in neck field. Results 14197 lymphatic nodes(LN) were detected in 213 case. The average number of resected LN was 66. 65 ±24. 73. The metastatic lymph node was detected in 105 cases. The metastatic rate was 49.05% (105/213).There were 423 metastatic lymph nodes. The lymph nodes metastasis was 2. 97% (423/14197) of all dissected lymphatic nodes. No remnant carcinoma in the upper and lower cutting edge was found in pathological examination. The operation time ranged from 2. 92 ～ 4. 67 ( 3. 37 ± 0. 42) hours. Blood transfusion during perioperative period was 0 ～ 6u ( 1.08 ± 0. 93 ) u. Perioperative plasma transfusion was 0 ～ 1400( 103.77 ± 184. 89) ml. The hospital-time was 14 ～ 39 ( 17.64 ±4. 12) days. There were no anastomotic leakage and recurrent laryngeal nerve injury. One case died from respiratory failure, the mortality was 0. 04% ( 1/213). Conclusion Surgical approach in the management of left thoracotomy in the sixth intercostals could extend resection of chest-field lymph node dissection, decrease neck field lymph node dissection. Abdomen-field lymph node dissection reached selected D3. The selected lymphadenectomy procedure had the advantages of small traumas and few complications.

Objective To study the effects of rational emotive behavior therapy (REBT) in the rehabilitation of patients with spinal cord injury (SCI).MethodsA total of 300 SCI patients from six institutions were divided into a research group and a control group. Systematic rehabilitation was given to the patients of the control group, while systematic rehabilitation and REBT were given to the patients of the research group. All patients were followed up for 1 year. Psychological state, activities of daily living (ADL), and quality of life (QOL) were evaluated with a symptom check list (SCL-90), a modified version of the Barthel index (MBI) and the World Health Organization's quality of life assessment (WHOQOL-100).ResultsOne year after treatment, the improvement in QOL of patients in the research group was better, on average, than that in the control group. The differences were primarily in mental items. The ADL ability of patients in both groups improved, and any differences were not significant. The psychological state of patients in the research group had improved significantly 1 year after treatment, while the improvements in the control group were not significant on average, except in terms of interpersonal sensitivity.ConclusionREBT had little effect on the ADL ability of SCI patients, however, it improved their psychological state significantly, and thus improved their QOL.

AIM: To detect the effect of conjunction matrigel with mammary fad pat(MFP)implantation on the tumorigenesis, proliferation, apoptosis and metastasis of Her2 positive and negative breast cancer model. METHODS: The Her2 positive BT 474 and Her2 negative MDA-MB 231 breast cancer cells were injected into MFP of nude mice with or without matrigel to establish breast cancer model. The tumor volume was measured every 3 d. Followed up for 30 d after implantation, the nude mice were killed and the tumors and associated organs were dissected for pathological sectioning and staining with hematoxylin and eosin. The time of tumor formation and the tumorigenesis were determined after implantation. The tumor volume and metastasis rate were calculated and compared with each other. The proliferation and apoptosis of Her2 positive and negative tumors were also determined. RESULTS: Matrigel and MFP implantation technology shortened the time of tumorigenesis significantly(P<0.01). The tumorigenesis rate of BT 474 and MDA-MB 231 breast cancer cells did not show any different(P>0.05). The metastasis rate of MDA-MB 231 breast cancer cells were improved from 25.0% to 37.5%(P<0.05). CONCLUSION: Matrigel and MFP implantation can be combined to shorten the time of tumor formation by two kinds of breast cancer cells, and improve the metastasis of Her2 negative MDA-MB 231 cells. Using matrigel does not show any effect of proliferation and apoptosis on Her2 positive and negative breast cancer cells.

Objective To explore the clinical characteristics and correlation of adult primary nephrotic syndrome (PNS) with thyroid dysfunction,and early identify high-risk adult PNS patients with abnormal thyroid function by clinical data.Methods The clinical data of 101 adult PNS patients in Heji Hospital Affiliated to Changzhi Medical College from March 2015 to December 2017 were retrospectively analyzed.According to the thyroid function,the patients were divided into 2 groups:normal thyroid function group (67 cases) and thyroid dysfunction group (34 cases),including 9 cases with low triiodothyronine (T3) syndrome and 25 cases with subclinical hypothyroidism.The clinical data were compared,and the correlation between thyroid-stimulating hormone (TSH) and 24 h urinary protein,blood albumin and systolic blood pressure were analyzed.Results The incidence of thyroid dysfunction in adult PNS patients was 33.66％ (34/101),including 21 cases of membranous nephropathy,8 cases of minimal change disease,4 cases of IgA nephropathy and 1 case of membranoproliferative nephritis.The 24 h urinary protein in thyroid dysfunction group was significantly higher than that in normal thyroid function group:(8.76 ± 3.62) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.82 ± 4.89) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05 or ＜0.01);there was no significant difference in gender composition,age,course of disease,systolic blood pressure,diastolic blood pressure,body mass index,hemoglobin,platelet,creatinine,cystatin C,fasting blood glucose,total cholesterol,triacylglycerol,low-density lipoprotein cholesterol (LDL-C),fibrinogen,complement C3,IgG,IgM,IgA,PNS types and comorbidities between 2 groups (P＞0.05).The results of subgroup analysis results showed that the systolic blood pressure in subclinical hypothyroidism patients of thyroid dysfunction group was significantly higher than that in normal thyroid function group and the low T3 syndrome patients of thyroid dysfunction group:(148.16 ± 18.09) mmHg (1 mmHg =0.133 kPa) vs.(139.55 ± 18.77) and (127.78 ± 16.81) mmHg,the 24 h urinary protein was significantly higher than that in normal thyroid function group:(9.00 ± 3.64) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.71 ± 5.26) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05).Pearson correlation analysis result showed that TSH had no correlation with 24 h urinary protein and systolic blood pressure (r =0.193 and 0.072,P =0.053 and 0.472);however TSH was negatively correlated with albumin (r =-0.340,P =0.001).Conelusions In adult PNS patients with thyroid dysfunction,membranous nephropathy is the most common,followed by minimal change disease.The systolic blood pressure in PNS patients with subclinical hypothyroidism is significantly higher than that in patients with normal thyroid function and low T3 syndrome.In adult PNS patients,the lower the blood albumin is,the more likely they have thyroid dysfunction.

Triptolide is a key active component of the widely used traditional Chinese herb medicine Tripterygium wilfordii Hook.F.Although triptolide exerts multiple biological activities and shows promising efficacy in treating inflammatory-related diseases,its well-known safety issues,especially reproductive toxicity has aroused concerns.However,a comprehensive dissection of triptolide-associated testicular toxicity at single cell resolution is still lacking.Here,we observed testicular toxicity after 14 days of triptolide exposure,and then constructed a single-cell transcriptome map of 59,127 cells in mouse testes upon triptolide-treatment.We identified triptolide-associated shared and cell-type specific differentially expressed genes,enriched pathways,and ligand-receptor pairs in different cell types of mouse testes.In addition to the loss of germ cells,our results revealed increased macrophages and the inflammatory response in triptolide-treated mouse testes,suggesting a critical role of inflammation in triptolide-induced testicular injury.We also found increased reactive oxygen species(ROS)signaling and down-regulated pathways associated with spermatid development in somatic cells,especially Leydig and Sertoli cells,in triptolide-treated mice,indicating that dysregulation of these signaling pathways may contribute to triptolide-induced testicular toxicity.Overall,our high-resolution single-cell landscape offers comprehensive information regarding triptolide-associated gene expression profiles in major cell types of mouse testes at single cell resolution,providing an invaluable resource for understanding the underlying mechanism of triptolide-associated testicular injury and additional discoveries of therapeutic targets of triptolide-induced male reproductive toxicity.
