Multiple myeloma (MM) is a malignant hematological disorder caused by the abnormal proliferation of monoclonal plasma cells. Traditional high-throughput cell sequencing reflects the heterogeneity of cell population, while it ignores the genetic information in single-cell. The development of single-cell sequencing has enabled the access to cell-to-cell variation in tumor and microenvironment of bone marrow, providing a deep understanding of the pathogenic mechanisms of MM and guidance for clinical treatment. This paper reviews the latest progress of single-cell sequencing and its application in disease pathogenesis, monitoring of disease progression, immunotherapy and therapeutic responses of MM.

Having been launched for almost two decades,the seven-year medical educational program in Jiangsu province has cultivated and exported a certain amount of popular high-level medical talents with high and integrated quality for our society.To establish and construct the medical educational hierarchy which takes the five-year program as the principal part while focuses on the eight-year program corresponding to our economic level will be the inevitable tendency for the development of the higher education in our province.

The effect of tumor necrosis factor (TNF) in combination with thymosin and chemotherapy on advanced primary liver cancer was observed. Eighty-nine advanced primary liver cancer cases were randomized into two groups: Patients in the control group were treated only with chemotheraputic drugs, and patients in the observing group were treated with TNF, thymosin and chemotheraputic drugs. The results showed that there were higher primary tumor regression rates and statistically reduced AFP in the observing group than control group. The rate of half year survival, one year survival and two years survival improved 28.6%, 18.0% and 5.1% than those of control group, respectively. We belived that this combined therapy could effectivelly improve the patients immunity, the quality of survival, and long the patients survival period.

Objective To study the protective effect of different doses of rosiglitazone (RSG)against focal cerebral ischemia-reperfusion injury in rats．Methods Forty male sprague Dawley rats were randomly divided into the following groups：sham-operation，control，lowdose RSG(1 mg/kg·d)，moderate-dose(2 mg/kg·d)，high-dose(4 mg/kg·d)goups(n=8 in each grow)．A rat model of middle cerebral artery occlusion for 2 hours and reperfusion for 22 hours were induced by the intraluminal suture method．An automatie biochemical analyzer was used to detect the blood glucose and lipid levels．A solid phase sandwich enzyme-linked immunosorbent assay was used to determine serum insulin levels，and the insulin sensitivity indexes were calculated．The effect of rosiglitazone on infarct volume and behavioristics was observed．Results Compared with the control group，the infarct volume was significantly reduced，and the neurological function scores were improved significantly in each RSG group(P<0．05 or P<0．01)．The insulin sensitivity was significantly increased(P<0．05 or P<0．01)，and hyperglycemia was reduced significantly after cerebral ischemia(P<0．05)and showed a dose-dependent manner.Conclusions RSG has obvious neuroprotective effect against cerebral ischemia／repeffusion injury in rats．Its mechanism may be associated with the increase of insulin sensitivity．

Objective Investigate the clinicopathological characteristics of h?rthle cell tumors of the thyroid. Methods Sixteen cases of HCT were studied by the clinicopathological study and immunohistochemical and review of the literature. Results There were 13 cases of h?rthle cell adenomas, 5 h?rthle cell follicular carcinomas. Immunostains showed that almost all benign and malignant HCT expressed TG, vimentin, S-100 protein. Conclusions HCT is a potential malignant tumor with a defined pathologic feature. It should be follow up for a longer time to their biological behaviors. To distinguish between the benign and the malignant depends on traditional encapsulation, and whether there is a blood vessel invasion or metastasis.

BACKGROUND:Can adipose-derived mesenchymal stem cells be used to treat sensorineural deafness caused by hair celldegeneration and loss? OBJECTIVE:To investigate the effect of adipose-derived mesenchymal stem cells from guinea pigs transplanted via the scala tympani on the recovery from sensorineural hearing in an animal model. METHODS:Intraperitoneal injection of gentamicin was performed to prepare sensorineural deafness models in guinea pigs. Then, adipose-derived mesenchymal stem cells from guinea pig were transplanted via the scala tympani. After 1 and 3 weeks, auditory brainstem responses were detected to observe the hearing variation after adipose-derived mesenchymal stem celltransplantation. Meanwhile, the migration and distribution of EDU-labeled adipose-derived mesenchymal stem cells in the cochlea were traced. RESULTS AND CONCLUSION:After 1 and 3 weeks of implantation, the results from auditory brainstem response showed that the hearing was gradual y improved. At 1 week of implantation, most of the cells were distributed in the perilymph and some cells migrated to the Corti organ and attached to the basement membrane. At 3 weeks of implantation, cells migrated and attached to the basement membrane of Corti organ, furthermore, some cells migrated to the cochlear nerve. The longer the time of implantation, the less cellsurvived. The results indicate that adipose-derived mesenchymal stem cells from guinea pig that are transplanted via the scala tympani can directly migrate and survive ultimately to improve the hearing.

Objective To determine the significance of MDR -1 and MRP mRNA expression in periph-eral blood lymphocytes in lung cancer patients with chemotherapy treatment .Methods Peripheral blood samples were taken from each lung cancer patient before chemotherapy and three weeks after the first chemotherapy cycle . The expressions of MDR-1 and MRP were tested for 39 lung cancer cases using RT -PCR technique comparing to 20 normal control cases .Results There was no significant difference for MDR -1 mRNA and MRP mRNA ex-isting in lung cancer cases and control group (P>0.05).MDR-1 and MRP mRNA expressions were increased after treatment of chemotherapy courses in almost all pathological types of lung cancer .Furthermore,the expres-sion level in small cell lung cancer after chemotherapy was significantly higher than that before .Conclusion Chemotherapy may induce the incidence rate of MDR -1mRNA and MRP mRNA expression in lung cancer .Ade-nocarcinoma and squamous cell carcinoma are mainly intrinsic MDR while small cell lung cancer is mainly ac -quired MDR to chemotherapy .Based on the positive expression rate of MDR -1 mRNA and MRP mRNA in pe-ripheral blood ,we may evaluate the results of chemotherapy in lung cancer patients easily and conveniently .

Objective To investigate the predictive value of metabolic tumor volume (MTV) in angiogenesis and hematoge‐nous metastasis of patients with colorectal cancer .Methods Totally 108 patients with colorectal cancer from January 2011 to De‐cember 2015 were enrolled into the study and divided into metastasis group (n=42) and non‐metastasis group (n=66) according to whether combining with hematogenous metastasis .All patients received 18 F‐2‐fluoro‐D‐glucose positron emission tomography/com‐puted tomography (18F‐FDG PET/CT) before operation ,then used the PET VERA software to automatically calculate MTV ac‐cording to the 40% of standard uptake value max(SUVmax ) as the threshold .The blood vessels were identified with CD34+ immu‐nohistochemical staining ,then measured the microvessel density (MVD) .The clinical pathologic data ,SUVmax ,MTV and MVD were compared between metastasis group and non‐metastasis group .The area under the receiver‐operating characteristic curve (AUC) was performed to evaluate the predictive value of MTV on hematogenous metastasis .Results SUVmax ,MTV and MVD in metastasis group were significantly higher than that in non‐metastasis group (P<0 .05) .There were significant differences in MTV and MVD among patients with different T stage (P<0 .05) .Pearson correlation analysis results showed that MTV was positively correlated with MVD (r=0 .636 ,P<0 .001) ,and there was no significant relationship between MTV and SUVmax (r= 0 .161 ,P=0 .096>0 .05) ,MVD and SUVmax (r=0 .179 ,P=0 .064>0 .05) .AUC of MTV was 0 .736 ,and the best threshold value was 15 .016 cm3 ,whose sensitivity ,specificity ,positive predictive value ,negative predictive value and Youden index were 83 .3% ,63 .6% , 59 .3% ,85 .7% and 47 .0% respectively .Conclusion Compared with SUVmax ,MTV of colorectal cancer is associated with angio‐genesis and hematogenous metastasis ,so as to predict the prognosis of colorectal cancer ,which is worthy of clinical application .
