Objective To investigate the effect of carotid artery stenting (CAS) on cognitive function in patients with asymptomatic severe carotid artery stenosis.Methods The patients with asymptomatic severe carotid stenosis (stenosis ≥ 70％) were enrolled in the study.The cognitive function evaluation was performed before CAS,1 and 3 months after procedure respectively with mini-mental status scale (MMSE),digital span (DS),Chinese auditory learning test (CALT),judgment of line orientation test (JLOT),and verbal fluency test (VFT),including attention,memory,visual spatial function,and frontal fluency function.Results A total of 26 patients with asymptomatic severe carotid artery stenosis who performed CAS were enrolled,18 were males and 8 were females (aged 52 to 79 years,mean 64.19 ±6.76 years),and the years of education was 9.84 ± 3.29 years.Eighteen patients had left carotid artery stenosis and 8 had contralateral carotid artery stenosis.CAS was performed successfully in all patients,and no complications occurred.Compared with the CAS before procedure,all the cognitive functions were improved significantly at 1 and 3 months after procedure (all P ＜0.01),however,there was no significant difference between 1 and 3 months after procedure (all P＞ 0.05).Conclusions CAS may improve cognitive function in patients with asymptomatic severe carotid artery stenosis,and it was more obvious in the early postoperative period.

Objective: To explore the effect of umbilical cord blood stem cell transplantation on axon regeneration in spinal cord injury (SCl)in rats. Methods: The umbilical cord blood was collected and prepared into suitable concentration of CD34 positive stem cells. Thirty SD rats were divided into two groups randomly. One group served as control, another one was the treatment group. The models of spinal cord contusion injury were made by Allen's weight dropping method. One week later,the treatment group was transplanted with 10x105 umbilical cord blood stem cells with Hamilton micro-syringe at the sites of rostral and caudal to the lesioned zone respectively, while control group received just the same volume of PBS injection. Five rats in each group were sacrificed at 1 w, 2 w and 6 w after this operation. Histological and immunohistochemieal examinations including GAP-43 and NF200 were used to evaluate axon regeneration. Meanwhile, BBB motion scoring and inclined plane test were performed to assess the motion function changes of hindlimbs. Results: Compared to the control group, the area of cavity in the lesioned spinal cord region decreased significantly and the expressions of GAP-43 and NF200 increased markedly in cell transplantation group. Also the motion function had better restoration in the treatment group. Conclusion: Transplantation of umbilical cord blood stem cell may achieve both morphological and behavioral improvement for the injured spinal cord.

Objective To analyze the outcomes and the prognostic factors of hematopoietic stem cell transplantation (HSCT) in combination with imatinib for Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). Methods All 32 patients with Ph+ ALL achieved hematologic complete remission (CR) at time of transplantation, including 27 cases in the first CR (CR1) and 5 in CR2. Nineteen patients achieved molecular remission (MR). Among 32 patients, 4 received autologous HSCT (AHSCT), and 28 allogeneic HSCT (allo-HSCT). The conditioning regimens comprised of total body irradiation (TBI), cyclophosphamide, fludarabine and cytarabine. The median number of transfused mononuclear cells was 5. 6 × 108/kg, and that of CD34+ cells was 2. 94 × 106 /kg. Thirty-one patients were administrated imatinib orally before transplantion, at a dose of 400～600 mg/day, and 16 patients after transplantation, including 7 for prevention at a dose of 300～400 mg/day and 9 for salvage treatment at a dose of 400 ～ 600 mg/day. Results Hematopoietic reconstitution was achieved in all 32 patients. Three-year estimate of overall survival (OS) was (62. 1±8. 6)%, leukemia-free survival (LFS) (59. 2 ± 8. 7)%, relapse rate (RR) (17. 7 ± 7. 2)% and transplant-related mortality (26. 2 ± 8. 0) %. All 4 undergoing AHSCT were alive, and 3 out of them were in continuous CR with durations of 14, 18 and 67 months respectively. The univariate analysis for prognosis in allo-HSCT showed that the OS of HLA-matched sibling donors group was 76. 5 %,higher than that of unrelated or haploidentical donors group (27. 3 %, P＜0. 05), and so was LFS (70. 6 % vs 27. 3 %, P＜0. 05). RR in patients achieving MR at time of transplantation was 5. 6 %,lower than that in those not achieving MR (40. 0 %, P＜0. 05). RR in patients in CR1 at time of transplantation was 12. 5 %, lower than that in those in CR2 (50 %, P ＜0. 05). Conclusion Imatinib improved the outcomes of HSCT for Ph+ ALL, especially to patients achieving MR at time of transplantation and transplantation in early stage (CR1).

Objective To explore the impact of IL-10 gene polymorphisms on the outcome in HLA matched sibling hematopoietic stem cell transplantation (HSCT).Methods PCR-sequencespecific primer (PCR-SSP) assay was used to analyze the SNP of IL-10 in 77 recipient and donor pairs:-1082 A/G,-819 T/C,-592 C/A.Results IL-10 ATA/ATA (1082,-819,-592) genotype in recipients significantly decreased the incidence of grade Ⅱ-Ⅳ acute graft vursus-host disease (aGVHD) (6.1％ vs.25.0 ％,P＜0.05),reduced 5-year transplant-related mortality (TRM) (10.7 ％± 5.9％ vs.29.7％ ± 5.2％,P＜0.05) and increased disease free survival (DFS) (81.8％ ± 6.7％ vs.56.8％ ± 7.5％,P＜0.05).With regard to the donor genotype,the incidence of grade Ⅱ-Ⅳ aGVHD,extensive chronic GVHD,5-year TRM and DFS had no signicant difference between IL-10 ATA/ATA and non ATA/ATA subgroup.Multivariable analysis also revealed that IL-10 non-ATA/ATA genotype in recipients and high-risk status of disease were two independent risk factors for DFS (HR =2.911,P =0.029; HR =2.686,P =0.027).Conclusion In HLA-matched sibling HSCT,the presence of recipient IL-10 ATA/ATA significantly decreased the incidence of grade Ⅱ-Ⅳ aGVHD and TRM,and increased DFS.

The design of a clip-on moxibustion instrument which could adjust the directions and absorb harmful granules of moxa smoke was introduced in this paper. It was designed to solve the problems in home health care and clinical treatment, such as the inconvenience of adjustment of moxibustion directions and temperature, more dust and granules of moxa smoke and inconvenience of moxibustion placement. The main part of moxibustion instrument was made up of moxibustion box, bracket and base clamp. The moxibustion box could fix moxa stick and absorb smoke granules; the bracket could be twisted to adjust the direction of moxibustion box; the base clamp was aimed to fix moxibustion box on the edge of the object to save space. This moxibustion instrument could be used for various indications of moxibustion, especially in the joints or body parts with less muscles; and it can significantly enhance the pertinence and safety of moxibustion, and reduce the labor intensity. This moxibustion instrument is original and unique, simple and reasonable, easy to operate, with low cost and good effect, which will increase new vitality for the popularization and development of moxibustion.

Objective: To investigate the clinical effects of sinus elevation surgery and implant restorationdue to insufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis (OMS) and to provide a reference for use in clinical practice. Methods: This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-five teeth were extracted from patients with OMS in the maxillary posterior area (the study group). Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group. Forty-eight teeth were extracted from patients without "OMS" in the maxillary posterior area (the control group), and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group. In the study group, 13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation, and the other 32 cases were addressed with crest-approach sinus elevation. In the control group, 8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation. Restorations were placed 6 to 8 months after surgery. The patients were followed up 21 days, 3 months, and 8 months after implantation and every 6 months after the placement of the restorations. The sinus bone gain (SBG), apical bone height (ABL) and marginal bone loss (MBL) were statistically analyzed 24 months after the restoration. Results: The average preoperative mucosal thickness in the 45 patients in the study group was (1.556 ± 0.693) mm, which was significantly larger than that in the control group (1.229 ± 0.425) mm (P<0.001). There were no perforations in either group. Twenty-four months after restoration, there was no significant difference in the SBG, ABH or MBL between the two groups (P>0.05). Conclusion After the extraction of teeth from patients with OMS, the inflammation of the maxillary sinus decreased, and the bone height and density in the edentulous area were restored to a certain degree. The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective: To discuss the effect of high-density fat-binding SVF-GEL in female facial lipofilling. Methods: This is a retrospective study including 32 female patients, received facial fat transplantation during June 2017 to June 2018 in Yichun College. Each patient underwent high-density fat-binding SVF-GEL transplantation for facial surgery. Patients′satisfaction with the surgery and the rate of secondary surgery was evaluated. Fat was harvested from the inner thigh, centrifuged at 1200 g for 3 min, and the liquid was removed. The upper 2/3 part is prepared for SVF-GEL, for further used in delicate lipofilling in eyelid, tear groove and nasolabial groove. The lower 1/3 high density fat was used for volume restoration, such as forehead, temporal area and cheek. Results: All patients had significant improvements in facial contours with mild swelling and short recovery time. The satisfaction rate was 68.8%(22/32), and the second operation rate was 15.6%(5/32). Conclusions High-density fat-binding SVF-GEL transplantation can achieve good results in correcting facial volume loss.

Objective: To investigate the clinical characteristics of salivary gland tumors and their pathological types. Methods: Data from 2 456 patients with salivary gland tumors diagnosed between January 1973 and December 2018 at Sun Yat-sen Memorial Hospital of Sun Yat-sen University were collected, and their gender, age and tumor pathological type, location, and benign and malignant composition ratios were retrospectively analyzed. Results: Over the 46-year study period, 2 456 patients with salivary gland tumors were treated; 41.9% were female, and 58.1% were male. The peak incidence was found among the 40 to 60 years of age group, in which 593 (24.1%) patients had malignant tumors and 1 863 (75.9%) had benign tumors. The ratio of benign and malignant tumors was 3.1∶1. The top two most common benign tumors were pleomorphic adenoma (58.7%) and Warthin tumors (33.6%). The top two most common malignant tumors were mucoepidermoid carcinoma (27.7%) and adenoid cystic carcinoma (26.1%). The most common sites of benign pleomorphic adenomas were the parotid glands, palate, and submandibular glands. Mucinous epidermoid carcinomas in malignant tumors were common in the parotid glands and small salivary glands. The incidence of salivary gland tumors in this group has increased each year, and this group accounted for 53.3% of the total cases over the past 10 years. Conclusion The number of patients with salivary gland tumors is increasing each year. The total incidence of salivary gland tumors is higher in men than in women. Large salivary gland tumors are mainly benign tumors, and small salivary gland tumors are more common. Polymorphic adenomas, Warthin tumors, and mucoepidermoid carcinomas are the most common tumor types; patients 40~60 years old are most likely to have benign salivary glands and have a high incidence of malignant tumors.

OBJECTIVETo explore the impact of interleukin-18 (IL-18) single nucleotide polymorphisms on outcomes of hematologic malignancies with HLA-matched sibling donor hematopoietic stem cell transplantation (allo-HSCT).

METHODSSingle- nucleotide polymorphisms in IL-18 promoter was detected by PCR-sequence-specific primer analysis (PCR-SSP) in 93 recipients and their HLA matched sibling donors. Hematopoietic reconstitution, incidences of graft versus host disease (GVHD) and infections, transplant related mortality (TRM), and disease free survival (DFS) were analyzed.

RESULTSIn comparison with -137 G/C+C/C donor genotype, patients with -137 G/G donor genotype had shorter duration of neutrophil recovery [15(11-23) days vs 17(11-24) days, P=0.01], higher incidence of extensive chronic GVHD (20.6% vs 3.3%, P=0.029), but no difference in the interval of platelet recovery [20(11-46) days vs 20(7-38) days, P=0.844]. The incidence of extensive chronic GVHD in -607 C/C donor genotype (31.6%) was significantly higher than that (10.8%) in C/A + A/A donor genotype (P=0.024). Recipients with -607 C/C genotype also had higher incidence (33.3%) of extensive chronic GVHD than those with C/A+A/A genotype (10.7%, P=0.016). There were no differences in acute GVHD, TRM, and DFS between different genotypes.

CONCLUSIONIL-18 -137 G homozygous genotype in donor facilitated neutrophil reconstitution, but increased the risk of extensive chronic GVHD in patients with allo-HSCT.
