Objective To analyze contrastly the effect of 89SrCl2 for bone metastasis in Uygur and Han patients with prostate cancer.Methods The curative effects in 75 Uygur and 82 Han patients with prostate cancer bone metastasis were investigated after intravenous injection with 89SrCl2,including palliation of pain.SPECT was used to detect the change of metastasis,level of prostate-specific antigen (PSA) and interleukin-6 (IL-6) were detected by electrochemiluminescence immunoassay.Results After treated with 89SrCl2,the palliation rate,the bone metastases and the level of IL-6 were higher in Uygur patients [82.67 ％ (62/75),75 ％ (56/75),(4.24±1.74) pg/ml] than those in Han patients [60.98 ％ (50/82),52.44 ％ (43/82),(2.81±2.38) pg/ml],and there were statistically significant (P ＜ 0.05).Conclusion 89SrCl2 is more effective for the Uygur patients with prostate cancer bone metastasis than the Han patients,clinical workers should pay more attention to this.

BACKGROUND:Traumatic auricle defectsin upper 1/2 or lower 1/2,seriously involve theauricular cartilage and skin blood vessels. The autogenic rib cartilage graft and acelular dermal matrix have good histocompatibility, and expanded flapis a kind of thin and achromatic tissue for skin defect repair. OBJECTIVE:To explore theapplication ofacelular dermal matrix and expanded flap in half auricular reconstruction,and to find out the fine carving and anastomosis of autogenic rib cartilage graftas wel as its similarities with the ear and clinical significance. METHODS:Eight cases of half auricular defects were treated with expanded flap, autogenic rib cartilage graft, fine anastomosisofautogenic rib cartilage graft and residual earfor half auricular reconstruction,during which theacelular dermal matrixwas usedto promote residual ear docking and skul auricle angle formation. The reconstructionwasperformed in three stages:first,anexpander(volume, 80mL)wassubcutaneously implanted attheretro-auricular area;second, the auricular defects were reconstructed with fine rib cartilage graft, acelular dermal matrix and auriculoplasty;finaly, acelular dermal matrixwas usedto promote residual ear docking. Thenthehalf auricular reconstructionwas evaluatedby objective measurement and subjective rating. RESULTS AND CONCLUSION:Half auricular reconstruction was successful in al the eight caseswithout obvious complications, and the cartilage grafts were in good condition.During thefolow-up,thereconstructed auriclewasshapedwel andformed a good involution withtheresidualauricle. In addition, the flange was smooth withoutobviouscolor difference and edema, and its position, size and shape were consistent with those of thecontralateralone. Afterthefolow-up of 6 months, objective indicators showed that the affected side had no significant differencefromthe contralateralone(P> 0.05). In conclusion,theacelular dermal matrixcanobviously decrease the complications of the cartilage grafts andcontributeto agood shaped auricle;and half auricular reconstructionby expanded flap, autogenic rib cartilage graft,andfine anastomosis of autogenic rib cartilage graftcanachieve significant clinical effects.

BACKGROUND:At present, the common filing materials used to correct secondary unilateral cleft lip nasal deformity include conchae cartilage, costal cartilage, Medpor implants, expanded polytetrafluoroethylene (ePTFE), alogenic acelular dermal matrix. OBJECTIVE:To analyze the therapeutic effects of comprehensive procedures with alogenic acelular dermal matrix or ePTFE for secondary unilateral cleft lip nasal deformity. METHODS: Thirty-six patients with secondary unilateral cleft lip nasal deformity were enroled, including 19 males and 17 females, aged 15-32 years. Alogenic acelular dermal matrix (n=22) or ePTFE (n=14) was used to correct nasal base colapse deformities. Anthropometry method was employed to make measurements. Fixed-point measurement was performed based on patient's pictures before and after correction. Long-term effects of these two kinds of filing materials were analyzed and assessed objectively and quantitatively. RESULTS AND CONCLUSION: After the folow-up of 6 months, al the patients were satisfied with their results, and no infection and no exposure occurred. The treatment effect of the alogenic acelular dermal matrix group was excelent in 16 cases and good in 6 cases; there were 10 cases of excelent and 4 cases of good in the ePTFE group. The objective indicators in the two groups were al improved at 6 months after correction (P < 0.05), but there was no difference between the two groups (P > 0.05). These findings indicate that alogenic acelular dermal matrix or ePTFE is useful to correct secondary unilateral cleft lip nasal deformity.

Objective To investigate microRNA expression profiles of colonic cancer without lymph node metastasis and identify the specific microRNAs associated with carcinogenesis of colon.Methods Cancerous and para-cancerous tissues (5 cm from cancer tissues of the colon) confirmed without lymph node metastasis were collected from 3 patients. The microRNAs were extracted and isolated by mirVana RNA kit. Hybridizations were made by applying the microRNAs to Agilent microRNA microarray. Data analysis was done by software of Feacture Extraction. The discovered microRNAs were confirmed by real time PCR assay. Results Twelve out of 14 microRNAs associated with colonic cancer were up-regulated in colonic tissues. They were miR-106b, miR-135b,miR-18a,miR-18b,miR-196b, miR-19a, miR-224, miR-335, miR-424, miR-20a' , miR-301b and miR-374a. The rest two of miR-378 and miR 378* were down-regulated. Two up-regulated microRNAs (miR-18a and miR-135b) were detected in 3 pairs of cancerous and para-cancerous tissues. The expression level of miR-18a and miR-135b were accordant with the results of real time PCR.Conclusions microRNA.such as miR-106b,miR-135b.miR-18a.miR-18b,miR-196b,ect,were differentially expressed between cancerous and para-cancerous tissues.Many of these target genes are supposed to participate in the process of multiple tunmorgenesis.These microRNAs play an important role in the carcinogenesis of colon.

The development of portable ultrasound equipment and point-of-care ultrasonography has promoted the application of ultrasound technology in the field of anesthesia and pain medicine.ultrasound is primarily used to evaluate blood volume and volume responsiveness,airway,lung and stomach volume,as imaging guidance tools for regional anesthesia and chronic pain management in perioperative and pain clinics.Transesophageal echocardiography is mainly used to obtain the information of cardiac anatomy,pathology and cardiac function.It is especially advantageous for the unsatisfactory image obtained by transthoracic ultrasound,left auricular thrombosis,infective endocarditis,aortic dissection,intraoperative monitoring,etc.The application of ultrasound technology improves the accuracy and safety of perioperative and pain medical diagnosis and treatment,and improves the quality of perioperative and pain medical treatment.

The incidence rate of thyroid cancer and thyroid nodule in China are rising and surgical operation is the main treatment for thyroid nodule and thyroid carcinoma.It has been controversial whether thyroid surgery is suitable for day surgery.Perfect preoperative examination and anesthesia assessment,selection of an appropriate of patients and minimally invasive surgery,good postoperative analgesia and the prevention and treatment of postoperative nausea and vomiting,recognition and treatment of postoperative complications timely,postoperative follow-up,can ensure safety of patient with thyroid ambulatory surgery,and made the same medical quality as the surgery in hospital.Under certain criteria,thyroid ambulatory surgery is safety,high efficient,economy and time-efficient.It is a reasonable surgical management mode which can reduce days of hospitalization and hospitalization cost.But it still need further study on the inclusion and exclusion criteria of patients,anesthesia techniques and perioperative management.

Objective:Through retrospective analysis of perioperative management data of ambulatory thyroid surgery under the concept of enhanced recovery after surgery (ERAS), we provide foundation for the safe implementation of ambulatory thyroid surgery.Methods:From January 2019 to December 2019, patients undergoing thyroid surgery were enrolled in the study under the concept of ERAS at the ambulatory surgery center of Xiangya Hospital, Central South University. Data of patients during perioperative period were collected, including adverse events, anesthesia recovery, postoperative and post-discharge recovery were recorded.Results:This study was included 703 cases of patients, thyroid nodules in 374 cases, thyroid malignant tumor in 329 cases. There were no significance difference in the operation time, anesthesia time, wake up of time, and postanesthesia care unit (PACU) time between the two groups (all P>0.05). No hypertension, hypotension, tachycardia, bradycardia or other arrhythmias occurred during perioperative period. No adverse events such as intraoperative awareness and delay of wake up occurred. No severe pain, nausea, vomiting, dizziness and other discomfort occurred after surgery. All 703 patients were discharged from hospital within 24 hours. Conclusions:Anesthesiologists participate in patient management according to the perioperative medicine requirements, and ambulatory thyroid surgery may be performed safely under the concept of ERAS.
