Result There were no complications were found, and the two cases were fully recovered and discharge from the hospital. Conclusion Sufficient preoperative preparation, earlier period vital sign monitoring,proper using of immunosuppressive agent,protecting complication protection, diet guidance, proper activity and resting, were the keys for the success of liver transplantation.

Objective:To assess the efficacy of trastuzumab combined with neoadjuvant chemotherapy in the treatment of human epidermal growth factor receptor-2 (Her-2)positive breast cancer patients,and to explore its influencing factors of prognosis of breast cancer.Methods:The clinical materials of 112 Her-2 positive breast cancer patients were collected and they were divided into combined treatment group (trastuzumab + neoadj uvant chemotherapy)and single chemotherapy group (without trastuzumab ). SPSS 1 9.0 software was employed to calculate and analyze their clinical characteristics.The survival rate and prognosis were analyzed by Kaplan-Meier method,Log-rank test, and Cox regression. Results:Among the 112 Her-2 positive breast cancer patients, 23 cases were treated with trastuzumab,89 cases were treated without trastuzumab.The disease-free survival (DFS)in combined treatment group and single chemotherapy group had significant difference (P=0.012).And there was no significant difference of overall survival (OS)between two groups (P=0.064).The HR negative group had 18 (32.7%)patients with 5-level of Miller and Payne (MP)classification which was higher than HR positive group (5/46,10.9%)(P=0.009).In univariate analysis,the tumor size,node status at diagnosis and node status after operation were the influencing factors of DFS in the Her-2 positive breast cancer patients;the tumor size,node status at diagnosis,MP classification and node status after operation were the influencing factors of OS in the Her-2 positive breast cancer patients.The result of multivariate analysis indicated that the tumor size, node status at diagnosis,and with or without radiotherapy were the independent influencing factors of DFS and OS in the Her-2 positive breast cancer patients. Conclusion:The breast lesions in the Her-2 positive breast cancer patients with negative HR are relieved after treated with trastuzumab combined with neoadjuvant chemotherapy. The combination of trastuzumab and neoadj uvant chemotherapy can significantly improve the DFS and has a positive influence in the prognosis of Her-2 positive breast cancer patients.

ObjectiveTo investigate the efficiency of autologous transplantation of peripheral blood stem cells for treatment of patients with diabetic lower limb ischemia.MethodsEighteen patients of type 2 diabetes with diabetic lower limb ischemia (30 legs) were treated by autologous transplantation of peripheral blood stem cells.ResultsThe limb pain, cool feeling and numbness feeling improved significantly after PBSC transplantation,the improvement rate were 96.7％, 100.0％ and 95.8％ respectively.Intermittent claudication was also relieved significantly, total remission rate was 76.9％.The ABI and TcPO2 of patients increased significantly at 3 months after transplantation.After the transplantation ABI raised from 0.60 ± 0.11 to 0.71 ±0.12(t =-6.882, P ＜ 0.01) .93.3％ of patients' TcPO2 raised in different degrees.The foot infections were well controlled.Ulcer or toes gangrene got better or healed.No obvious complications or adverse reaction were observed after the transplantation.ConclusionAutologous transplantation of peripheral blood stem cells shows to be a simple, safe and effective method in treating patients with diabetic lower limb ischemia.

Objective To detect the DMD gene mutation sites and the regions of breakpoints in Duchenne/Becker muscular dystrophy (DMD/BMD) patients in northern China. Methods Multiplex amplifiable probe hybridization (MLPA) was used to detect the mutation in 59 cases (51 cases with DMD and 8 with BMD) from northern China and dystrophin gene mutations in their parents. Results From northern China and dystrophin gene mutations 59 families found gene deletions in 33 cases of 59 DMD/BMD patients (55.9%), duplications in 6 cases (10. 2%) and point mutation in one case (1.7%). Intron 44 was most frequently affected (n = 13, 33.3%), followed by intron 50 (n = 11, 28.2%) and intron 45 (n=8, 20.5%). The novel mutations were identified, in two patients including two independent duplications carried by patient D1 149 and a point mutation [5208del(A)] carried by patient D1 65, which were not included in Leiden database. In addition, an exon 22 deletion was found in one patient, which was the first reported case in Chinese patients. Conclusions Deletions are mostly located in the hotspot between exon 45 and 50. Duplications mostly occurred in the 5' end of the gene. Intron 44 is the most frequently affected breakpoint in northern Chinese population.

Objective To investigate the safety and efficiency of robot-assisted partial nephrectomy (RAPN) for totally intrarenal tumors (TITs).Methods Thirty-eight patients who underwent RAPN for treating TITs by one experienced surgeon were included between August 2012 and December 2017.There were 25 males and 13 females,aged 26-72 years(mean 51.6 years).Tumors of 24 cases were in right kidney,and 14 cases in left kidney.The diameter of tumor was(3.12 ± 0.92) cm,the R.E.N.A.L.score was(9.76 ± 1.00),and the Scr was (74.82 ± 20.32) μmol/L.Patients' peri-operative and oncological outcomes were analyzed.Results All the tumors were successfully resected without conversion to open surgery or radical nephrectomy.Mean operative time and ischemia time were (188.47 ± 46.75) min and (24.32 ± 7.69) min.Mean blood loss was (115.79 ± 43.66) rrd.One-week postoperative Scr was (85.97 ± 28.33) μmol/L.Postoperative hemorrhage was successfully treated by DSA or drug therapy in 3 patients.The pathological examination showed 28 clear cell renal cell carcinomas,3 chromophobe renal cell carcinomas,3 TFE-3 infusion related renal cell carcinomas,2 metanephric adenomas,1 acidophile adenoma and 2 angioleiomyolipomas.One positive surgical margin occurred in RAPN group for cystic components.No evidence of tumor progression observed during follow-up.Conclusions RAPN is safe and effective in treating TITs when performed by an experienced surgeon at a high-volume institution.Further prospective and large-scale study was warranted to evaluate the long-term outcomes.

Objective To compare genomic copy number variations (CNVs) among different subtypes of breast cancer and analyze specific CNVs in each subtype. Methods AIMS software was used for genotype breast cancer (BasL, Her2, LumA and LumB), and GISTIC2.0 software was used to analyze genome-wide CNVs in tumor tissues from TCGA. We collected and analyzed the information and samples of 324 cases of invasive breast cancer admitted to Jiangmen Central Hospital(JMCH). Fluorescence quantitative PCR was used to detect the CNV of ERBB2, TFDP1, MIR148B, CCND1, MDM2 and MIR139 genes in the tumor tissues, to verify TCGA analysis. Results 13q34 was specifically amplified and 12q13.13 was specifically deleted in BasL-type breast cancer. The 17q12 was specifically amplified in Her2 type. The 12q15 was specifically amplified and 11q13.4 was specifically deleted in LumB type, but LumA type had no specific amplification or deletion of chromosome region. The proportion of TFDP1 amplification or MIR148B deletion in BasL type were 57.8% (TCGA) and 71.4% (JMCH), which were significantly higher than other subtypes (P < 0.001). The proportion of ERBB2 amplification of Her2 type were 55.2% (TCGA) and 86.7% (JMCH), which were significantly higher than other subtypes (P < 0.001). The proportion of LumB type with CCND1 or MDM2 amplification or MIR139 deletion were 47.6% (TCGA) and 61.8% (JMCH), which were significantly higher than other subtypes (P < 0.05). Conclusion At the CNV level of breast cancer, Her2 type is characterized by the amplification of ERBB2, BasL type is characterized by the amplification of TFDP1 or the deletion of MIR148B, LumB type is characterized by the amplification of CCND1 or MDM2 or the deletion of MIR139, but LumA type lacks specific CNV characteristics.

Malaria is one of the major diseases threatening the lives of people in Africa. Over the past decade, China has provided anti-malaria assistance to Africa. In November 2007, fast control malaria team of Guangzhou University of Chinese Medicine cooperated with the Comoros health authority. In Moheli Island of the Comoros, the anti-malaria team adopted a new strategy of Mass Drug Administration (MDA) and active intervention. They established an effective anti-malaria system and reporting system, as well as a local anti-malaria team. Furthermore, they treated patients with malaria in Moheli Island and implemended health education in local people. In a very short time, they have achieved remarkable results. This paper summarized the experiences of the project in order to provide useful reference for China to better carry out anti-malaria action in Africa and expand foreign health assistance.

The access negotiations of National Reimbursement Drug List (NRDL) in China from 2017 to 2019 effectively improved the availability and affordability of high-value innovative drugs. However,the actual outpatient reimbursement of most negotiated drugs is lower,which affects the patients" health insurance funds. In this paper,97 negotiated drugs in 337 overall planning cities were selected as samples to analyze the outpatient reimbursement for negotiated drugs. The results showed that the reimbursement level of 40 negotiated drugs was less than 50% in over 70% cities,which can be mainly interpreted as absence or imperfection of outpatient reimbursement policies for special diseases. Finally,this paper puts forward suggestions and protocols for improving the outpatient medical insurance through realizing outpatient overall planning,improving outpatient reimbursement policies for special diseases,and exploring innovative payment,ensuring the achievement of the access to NRDL.

Objective To compare the operative-postoperative outcomes of laparoscopic and robotassisted partial nephrectomy (LPN and RAPN) for patients with T1 b renal masses.Methods A total of 169 T1 b renal mass patients receiving LPN (n =69) or RAPN (n =100) in our center between October 2009 and October 2017 were retrospectively collected.There were 46 males and 23 females in LPN group,with a mean age of (55.0 ± 11.9) years.The mean tumor size was (5.09 ± 0.76) cm,and mean R.E.N.A.L score was 6.36 ± 1.53.49 procedures (71％) were performed via a retroperitoneal approach in LPN group.There were 59 males and 41 females in RAPN group with a mean age of (52.9 ± 11.7) years.The mean tumor size was(4.95 ±0.66) cm,and mean R.E.N.A.L score was 8.17 ± 1.50.31 procedures (31％)were performed via a retroperitoneal approach in RAPN group.There was statistical significance between two groups in R.E.N.A.L score and surgery approach (P ＜ 0.001).The group covariates were balanced through propensity score matching (PSM) using 1∶ 1 nearest neighbor matching method.After PSM,operating time,estimated blood loss,warm ischemia time,incidence of complications,hospital stay and postoperative follow-up status were compared between LPN(n =36)and RAPN(n =36)group.Results After PSM,patient distributions were closely balanced.In the LPN vs the RAPN group,there were significant different in warm ischemia time [(23.9 ± 7.3) min vs.(20.4 ± 6.7) min,P ＜ 0.05],estimated blood loss [(136.9 ± 80.2) ml vs.(136.9 ± 80.2) ml,P ＜ 0.05],incidence of complications (8.7％ vs.1.0％,P ＜0.05),and hospital stay [(11.5 ±3.8)d vs.(9.8 ± 1.80)d].There was no significant differences resulted regarding operating time [(164.5 ± 64.4) min vs.(169.0 ± 42.5) min,P ＞ 0.05],variation of estimated glomerular filtration rate from baseline [(9.97 ± 8.98)％ vs.(9.27 ± 9.19)％,P ＞ 0.05],positive surgical margin rate (1.4％ vs.0,P ＞ 0.05) and rate of recurrence or metastasis (1.4％ vs.1.4％,P ＞ 0.05) between groups.Conclusion Considering operative,functional and oncologic outcomes,both RAPN and LPN performed by an experienced surgeon were acceptable for patients with T1b renal masses.If available,robotic approach may reduce operative trauma and complications.

Objective:To explore the influencing factors of 31-day unplanned readmission in obstetrics.Methods:The medical records and relevant clinical data of 29 public hospitals in a province in 2017 were collected to construct a two-level logistic regression model on the influencing factors of 31-day unplanned readmission.Results:In 2017, there were 71 330 obstetric patients discharged from 29 public hospitals, 690 of whom were unplanned readmitted in 31 days, accounting for 0.97%. The type of medical insurance payment, number of previous hospitalization, condition of previous hospitalization, age, history of cesarean section, pregnancy complications and complications during delivery were all the factors influencing the 31-day unplanned readmission of obstetrics.Conclusions:The condition of 31-day unplanned readmission could be influenced by the factors of sociology, previous visit and clinical. These factors should be considered reasonably in the evaluation and management of obstetric quality.
