Objective To evaluate the efficacy of siege scheme of TCM for acute cerebral infarction bowel and visceral strike (block pattern). Methods Totally 110 patients were randomly divided into TCM siege scheme group (55 cases) and control group (55 cases) by randomized parallel controlled study with foresight and multicenter. The control group was treated with the standardized treatment, and TCM siege scheme group was treated with TCM siege scheme, including mild hypothermia TCM pillow therapy, TCM rectal enema, and other multiple treatments based on the standardized treatment. The Glasgow Coma Scale (GCS), the time of pulling out urine tube and nasal feeding tube, and the number of tracheotomy caused by illness changes of the two groups were compared. Results The baseline data of two groups have good comparability (P>0.05). On 10, 15 d of treatment, the number of lucid people in the TCM siege scheme group was significantly more than that in the control group (P<0.05). Compared with the control group, treatment group had less number of tracheotomy, and shorter time of success pulling out urine tube and nasogastric feeding tube (P<0.05). Conclusion TCM siege scheme can improve the consciousness of ischemic stroke in patients with acute cerebral infarction bowel and visceral strike, reduce complications, shows shorter successful pull urine tube and nasogastric feeding, and provides guarantee conditions for further rehabilitation treatment.

OBJECTIVETo investigate the effect of different concentrations of fluoride on the expression of transforming growth factor-beta1 (TGF-beta1), and explore the mechanism of dental fluorosis.

METHODS40 Wistar rats were randomly divided into three groups, and supplied with low dose F(-)(60 mgxL(-1), 13 rats), high dose F(-)(120 mgxL(-1), 13 rats) and distilled water(control group, 14 rats) respectively. After 10 weeks, hematoxylin-eosin (HE) and immunohistochemistry staining were used to observe the changes of the ameloblasts and the expression of TGF-beta1 in rat incisors.

RESULTSThe fluoride groups showed typical symptoms of dental fluorosis. The surfaces of the rat teeth fed with fluoride appeared chalky color and cross striation on the enamel surface. The HE staining showed that the morphous of ameloblast were disarranged and cellular derangement, even appeared vacuolar change. TGF-beta1 were expressed both in ameloblast of the secretory and maturation stage, and also in stellate reticulum and stratum intermedium. The expression of TGF-beta1 in rat's ameloblasts in experiment group was significantly lower than that in the control group (P<0.01), yet low dose group and high dose group still had no significant difference (P>0.05).

CONCLUSIONBy inhibiting the expression of TGF-beta1 in ameloblast, fluoride interferes the normal signal transduction between epithelial and mesenchymal, and affect the differentiation and development of enamel, so leading to the occurrence of dental fluorosis.

Objective: To investigate the safety and efficacy of 125I radioactive seed implantation in the treatment of mediastinal lymph node metastasis. Methods: Records of 53 patients enrolled in Shaanxi Provincial Tumor Hospital from June 2014 to June 2018 with me-diastinal lymph node metastasis treated by computed tomography (CT)-guided 125I seed implantation were analyzed retrospectively. The preoperative treatment planning system was validated after the surgery. Intraoperative and post-operative complications were re-corded. The improvement in quality of life was observed. Chest CT follow-up was conducted 1 month, 3 months, 6 months, 1 year, and 2 years after treatment. The local focus control was evaluated. The median survival and total survival were recorded, and the survival prognosis and causes of death were analyzed. Results: The median survival time was 254 days (8.5 months), one-year survival rate was 48.67%, and complete and partial response rate was 83.02% (44/53). Multivariate Cox model analysis showed that the survival progno-sis was related to the Eastern Cooperative Oncology Group (ECOG) score, distant metastasis at the time of implantation, concurrent chemotherapy after implantation, and secondary seed implantation (P<0.05). The rates of developing pneumothorax and hemoptysis during and after the surgery were 20.75% (11/55) and 13.20% (7/55), respectively. No patients died. After implantation, the remission rate of cough, shortness of breath, pain, hoarseness, and superior vena cava syndrome was 60.00%-82.61%. Conclusions: CT-guid-ed 125I seed implantation in the treatment of mediastinal lymph node metastasis has the advantages of minimal trauma, remarkable cu-rative effect, safety, and feasibility. It has important application value and is worthy of further clinical application.

Objective:To investigate the safety and dose of 4D template (real-time adjustable angle template) in the treatment of advanced malignant tumors with 125I seeds. Methods:98 patients with advanced malignant tumors admitted to Department of Thoracic Surgery of Shaanxi Provincial Tumor Hospital were treated with 4D template-navigated radioactive 125I seed implantation from June 2018 to December 2019. Preoperative TPS plan, intraoperative optimization, postoperative verification of immediate dose and postoperative evaluation of implantation dose were performed. The treatment results were observed. Results:All 98 patients completed the seed implantation. The implantation dose of GTV of implantation site receiving external irradiation was (12 489±414) cGy and the dose of no external irradiation was (15 036±514) cGy. V 100% was 84.7%-94.1%, and 88.2%-93.7%. The implantation dose of CTV was (7 450±621) cGy, and (9 080±761) cGy. The quality of dose implantation was evaluated as: excellent in 89 cases (91%, 89/98), good in 7 cases (7%, 7/98), fair in 2 cases (2%, 2/98), and poor in 0 case, respectively. The symptom relief rate of patients with pain was 92%(36/39). The 1-and 2-year local control rates were 61%, 36% and 82%, 54% in patients treated with and without external irradiation, respectively. The difference was statistically significant ( P=0.02). The incidence rates of pneumothorax and hemoptysis were 19%(9/48) and 10%(5/48). No corresponding complications were observed in other parts of the patients. Conclusion:4D template-assisted 125I seed therapy is safe and effective for malignant tumors, and intraoperative adjustment of needle angle and dose optimization can realize the precise control of implantation dose.

Objective: To explore the relationship between different serum albumin and lymphocyte levels in patients with 2019-novel coronavirus (2019-nCoV) pneumonia (COVID-19). Methods: A retrospective study was performed to identify the characteristics of the clinical data of 205 COVID-19 patients who were hospitalized in the Happy Street of Hanchuan People's Hospital, Xiaogan, Hubei Province from January 24 to February 12, 2020, including their general information, serum albumin (ALB) levels, lymphocyte counts (LYM), percentage of lymphocytes (LYM%) and other laboratory parameter levels. Low ALB group and normal ALB group were demarcated by the concentration of 35g/L, further to identify the differences of LYM and LYM% levels and the incidence of LYM and LYM% decline at different ALB levels between groups,as well as the correlation between ALB and LYM, LYM% levels in hypoalbuminemia conditions . Results: 17.5% of COVID-19 patients were associated with hypoalbuminemia. The levels of LYM and LYM% in the low ALB group were significantly lower than those in the normal ALB group (P <0.001). The incidence of LYM and LYM% decline in the low ALB group was significantly higher than those in the normal ALB group (P <0.001). The levels of LYM and LYM% in the low ALB group were significantly positively correlated with serum ALB concentrations (P <0.05). Conclusions The decrease of lymphocyte levels in COVID-19 patients may be correlated to hypoalbuminemia. COVID-19 patients complicated by hypoalbuminemia should be actively intervened to maintain serum albumin in the normal range.
