Objective To compare the clinical effects of guided tissue regeneration (GTR) combined with different bone graft materials, including Bio-Gene, Bone3 and Bio-Oss, in the treatment of periodontal intra-bony defects. Methods Eighteen patients with chronic periodontitis with periodontal intra-bony defects were randomly divided into the Bio-Gene group, the Bone3 group and Bio-Oss group. After periodontal debridement, periodontal bone grafting combined with GTR surgery was performed in all patients. The clinical and radiographic parameters of patients were collected before surgery, suture removal (2 weeks after surgery), and 6 months after surgery, including periodontal exploration depth (PD), clinical attachment loss (CAL), gingival recession (GR), and residual alveolar bone height (RBH). Results The wounds healed well in all patients when the suture was removed. The stage Ⅰ healing was obtained without infection or wound dehiscence, and the postoperative discomfort was acceptable. At 6 months after periodontal bone grafting combined with GTR treatment, the PD and CAL indexes in the three groups were significantly improved compared with those before surgery (all P<0.05), and there was no significant difference in PD and CAL between the three groups (all P>0.05). Imaging results showed that new bone formation was observed in the original bone defect area in all three groups after 6 months of the treatment, the bone density was similar to the surrounding bone tissue. Besides, the RBH％increased significantly compared with that before the treatment (all P<0.05), and there was no significant difference in RBH％among the three groups (all P>0.05). Conclusions Bio-Gene, Bone3 and Bio-Oss are all reliable bone graft materials for the treatment of alveolar bone defects caused by periodontitis, which can significantly improve the osteogenesis effect.

Objective To review the clinical characteristics and risk factors of Pseudomonas aeruginosa bloodstream infections. Methods The clinical data of P. aeruginosa bloodstream infections in the First Affiliated Hospital of Soochow University from January 2007 to December 2016 were analyzed retrospectively. Results Of the 251 patients identified, APACHE Ⅱ score on admission was 11.5±5.2. Majority (98.4％, 247/251) of the patients had fever. Leukopenia was found in 125 patients, leukocytosis in 87 patients, neutropenia in 122 patients, agranulocytosis in 113 patients, anemia in 193 patients, and hypoalbuminemia in 120 patients. Overall, 219 patients had at least one underlying disease, primarily hematological malignancy, or malignant solid tumor. Most (229) patients received invasive procedures such as deep venous catheter, urinary catheter, mechanical ventilation before blood sampling. P. aeruginosa was isolated from 108 of the 173 deep venous catheters. In addition, 130 patients received radiation or chemotherapy. Immunosuppressive agents were used in 124 patients. Among the 251 strains of P. aeruginosa, 87.3％ were susceptible to amikacin, followed by ciprofloxacin (85.7％) and cefepime (81.6％). Multidrug-resistant P. aeruginosa was isolated from 36 (14.3％) patients, and extensively drug resistant strain was isolated from 7 patients. All the 251 patients were treated withantimicrobial agents, mainly β-lactam/β-lactamase inhibitor combinations, carbapenems or fluoroquinolones. Overall, 20 (8.0％) of the 251 patients died, 37 (14.7％) refused further therapy due to worsening condition, and 194 (77.3％) improved. Binary logistic regression analysis showed that high APACHE Ⅱ score on admission, anemia and hypoalbuminemia were risk factors for poor outcome of bloodstream infectionscaused by P. aeruginosa. Conclusions P. aeruginosa bloodstream infection occurs more readily in immunocompromised patients. High APACHE Ⅱ score on admission, anemia and hypoalbuminemia are associated with poor prognosis. Appropriate empiric antimicrobial treatment as early as possible can improve the prognosis of P. aeruginosa bloodstream infection.

Objective: To investigate the application of single-molecule PCR (SM-PCR) in the detection of plasma ctDNA for the treat-ment of patients with advanced lung adenocarcinoma. Methods: In total, 30 patients diagnosed with advanced lung adenocarcinoma were enrolled between June 2017 and May 2018. ctDNA fragments of the target genes (EGFR, KRAS, BRAF, ALK, HER2, and TP53) from the blood samples were enriched by SM-PCR, and DNA libraries were prepared. Finally, a high-throughput sequencing was performed. The EGFR detection of tumor tissue samples was performed using real-time fluorescence PCR based on the amplification refractory mutation system (ARMS) and consistency in the results of EGFR mutation detection in the plasma and tissue was compared. Results:The results of both the methods were consistent (Kappa=0.867, P<0.001). The McNemar's test also indicated that the results are not statistically different (P=0.500). Conclusions: SM-PCR can be used for the detection of plasma EGFR mutations. The target detection sites are more comprehensive and multiple mutations can be detected at the same time. Results of the analysis are more precise and can be absolutely quantified.

Objective To investigate the medication and blood glucose control of type 2 diabetes patients under chronic diseases management in Xi'an chain pharmacies,and provides reference for improving the management policy of diabetes at grassroots level.Methods A number of chain pharmacies in the sixth district of Xi'an were selected by random sampling method,and on-site interviews were conducted by questionnaire survey to patients with type 2 diabetes under the management of chronic diseases.The basic information of patients,medication status(medication plan,drug adherence,etc.),diabetes-related conditions(blood glucose status,family history,course and complications,etc.)were collected.Multivariate logistic regression was used to analyze the relevant factors of blood glucose control in patients.Results A total of 403 patients were surveyed,the largest number of patients use oral hypoglycemic drugs alone(53.4％),followed by insulin medication(including insulin only and insulin in combination with oral hypoglycemic drugs)(35.7％),and the differences between disease course and glycemic control among patients with different drug regimens were statistically significant(P＜0.05).Only 43.7％of patients had good medication compliance.In addition,the patient's fast plasma glucose compliance rate was only 39.2％.The results of multivariate logistic regression analysis showed that good medication compliance(OR=1.744,95％CI 1.104 to 2.754,P=0.017)were independent influencing factors for achieving glycemic control.Conclusion The medication compliance of type 2 diabetes patients with poor blood glucose control in chronic disease management of chain pharmacies in Xi'an needs to be strengthened.Pharmacies should emphasize and give full play to the professional and service advantages of pharmacists to realize the functional role of pharmacies and strengthen diabetes management.

Objective:To investigate the clinical characteristics, treatment and prognosis of newly-treated patients with primary central nervous system lymphoma (PCNSL).Methods:Clinical data of 117 newly-treated PCNSL patients who were admitted to the First Hospital of Jilin University, the Fifth Medical Center of Chinese PLA General Hospital, Harbin Medical University Cancer Hospital, and Cancer Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College from August 2009 to February 2018 were retrospectively analyzed. The patients' age, sex, Eastern Cooperative Oncology Group (ECOG) physical status (PS) score, pathological type, involvement of deep brain tissue, number of lesions, cerebrospinal fluid protein concentration, International Extranodal Lymphoma Study Group (IELSG) score, Memorial Sloan Kettering Cancer Center (MSKCC) score, treatment strategy, and response after the first-line therapy were analyzed using univariate and multivariate Cox proportional hazards models to identify the independent influencing factors for progression-free survival (PFS) and overall survival (OS) of PCNSL patients. Kaplan-Meier method was used for survival analysis.Results:In 117 newly-treated PCNSL patients, 59 cases (50.4%) presented with increased intracranial pressure or focal neurological symptoms at diagnosis; there were 65 cases (55.6%) with single lesions and 52 cases (44.4%) with multiple lesions; 1 patient (0.9%) had lymphoma of T-cell origin, and 116 cases (99.1%) had diffuse large B-cell lymphoma (DLBCL). Among 95 evaluable patients, 41 patients (43.2%) achieved complete remission (CR), 20 patients (21.1%) achieved partial remission (PR), 16 patients (16.8%) achieved stable disease (SD), and 18 patients (18.9%) had progressive disease (PD). In 117 patients with median follow-up of 66.0 months (95% CI 57.9-74.1 months), the median PFS and OS were 17.4 months (95% CI 11.5-23.3 months) and 45.6 months (95% CI 20.1-71.1 months), respectively. The 2-, 3- and 5-year PFS rates were 41.2%, 28.6% and 19.3%, and OS rates were 63.7%, 52.4% and 46.3%, respectively. Univariate Cox regression analysis showed that baseline high-risk MSKCC score group was an adverse prognostic factor for PFS ( P = 0.037), and the first-line chemotherapy with ≥4 cycles of high-dose methotrexate (HDMTX), HDMTX in combination with rituximab, ≥4 cycles of rituximab in combination with HDMTX, and achieving CR or ≥PR after the first-line treatment reduced the risk of disease progression and prolonged the PFS time (all P <0.01); age >60 years old, ECOG-PS score of 2-4 points, elevated cerebrospinal fluid protein concentration, high-risk IELSG score, and high-risk MSKCC score were adverse prognostic factors for OS, and ≥4 cycles of HDMTX and achieving CR or ≥PR after the first-line treatment were favorable factors for OS. Multivariate Cox regression analysis verified that rituximab in combination with HDMTX (yes vs. no: HR = 0.349, 95% CI 0.133-0.912, P = 0.032) and achieving ≥PR after the first-line chemotherapy (yes vs. no: HR = 0.028, 95% CI 0.004-0.195, P < 0.001) were independent favorable factors for PFS; age >60 years old (>60 years old vs. ≤60 years old: HR = 10.878, 95% CI 1.807-65.488, P = 0.009) was independent unfavorable factor for OS, while ≥4 cycles of HDMTX treatment (≥4 cycles vs. <4 cycles: HR = 0.225, 95% CI 0.053-0.947, P = 0.042) was independent favorable factor for OS. Conclusions:The older the PCNSL patients at initial treatment, the worse the prognosis. Intensive and continuous treatment for achieving deeper remission may be the key for improving the outcome of PCNSL patients.

In recent years, the number of advanced non-small cell lung cancer (NSCLC) patients has gradually increased, and the treatment methods have also been significantly increased. However, there are no standard treatment plans at home and abroad for third-line and above patients who are refractory to targeted therapy epidermal growth factor receptor (EGFR)/anaplastic lymphoma kinase (ALK) or chemotherapy. The clinical treatment effect is also not satisfactory. Anlotinib is a novel TKI targeting the vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptor (PDGFR) and c-Kit. ALTER0303 trail, phase III study has demonstrated that Anlotinib significantly prolonged overall survival (OS) and progression-free survival (PFS) in advanced NSCLC patients as 3rd line treatment.Here we report a case of advanced lung adenocarcinoma harboring KRAS mutation treated with Anlotinib.
