Objective To explore the feasibility of labeling in vitro rabbit osteoblasts with Qtracker and the features of Qtracker-labeled rabbit osteoblasts. Methods A healthy male rabbit, 3 months old, weighing 2 kg, was used in this study. After bone marrow was aspirated, bone marrow stromal cells (BMSCs) were isolated and cultured using the adherence method in vitro. The third passage of BMSCs was induced into osteablasts before incubation with Qtracker at concentrations of 1, 2, 4, 8, 16, 32 nmol/10~6 cells (Groups A, B, C, D, E, F respectively). Cells not labeled by Qtracker served as negative control (Group G). The following parameters were measured: induction, differentiation and determination of rabbit osteoblasts; the optimal mass concentration of Qtracker labeling by fluorescence microscopy and flow cytometry; the cell sur-vival rates at various concentrations of Qtraeker labeling by trypan-blue exclusion; Qtracker-labeled cell pro-liferation by MTr. Results The primary and the passage rabbit BMSCs were chiefly of fusiform shape. Rabbit BMSCs differentiated into osteoblasts following induction. The osteoblasts cytoplasm showed green fluorescence under fluorescence microscopy after being labeled by Qtracker. The mean labeling rate increased with the increased concentration of Qtracker, reaching up to (93.58±2.08) % after incubation at 8 nmol/ 10~6 cells by fluorescence microscopy, and (95.24±1.31) % by flow cytometry. There were no significant differences between Groups D, E, F(P>0.05), but significant differences were found between Groups A, B, C and Groups D, E, F (P<0.05). The labeling rate for Group G was 0. The cell survival rates were all above 96% (P>0.05) . No significant differences were found in the cell proliferation among various con-centrations (P>0.05). Conclusions Qtraeker can be used as a labeling marker for rabbit osteoblasts. When the concentration is at 8 nmol/10~6 cells, optimal labeling effect can be achieved. Rabbit osteoblasts labeled with Qtracker are of high efficiency and safety.

Liver transplantation is one of the main treatments of early hepatocellular carcinoma (HCC). The recurrence of HCC after liver transplantation severely affects the long-term survival rate of the recipients. Targeted therapy and immunotherapy play a critical role in HCC downstaging, preventing disease progression, reducing recurrence rate, prolonging the survival and improving the quality of life. However, no consensus has been reached on the application of targeted therapy and immunotherapy in recipients undergoing liver transplantation for HCC, including indications, timing and dosage. In this article, clinical research progresses on the indications and timing of targeted therapy and immunotherapy before and after liver transplantation for HCC were reviewed, aiming to provide reference for prolonging the survival of recipients after liver transplantation for HCC.

OBJECTIVE:
To explore the genetic basis for a family with non-syndromic autosomal recessive deafness.
METHODS:
The proband and her parents were subjected to physical and audiological examinations. With genomic DNA extracted from peripheral blood samples, next-generation sequencing was carried out using a panel for deafness genes. Suspected mutation was validated by Sanger sequencing and qPCR analysis of her parents.
RESULTS:
The proband presented bilateral severe sensorineural hearing loss at three days after birth. Her auditory threshold was 110-120 dBnHL but with absence of vestibular and retinal symptoms. Her brother also had deafness but her parents were normal. No abnormality was found upon physical examination of her family members, while audiological examination showed no middle ear or retrocochlear diseases. Next-generation sequencing identified compound heterozygous mutations of the MYO7A gene, including a previously known c.462C>A (p. Cys154Ter) and a novel EX43_46 Del, which were respectively derived from her mother and father.
CONCLUSION
The compound heterozygous mutations of the MYO7A gene probably underlie the disease in this family. Our findings has enriched the mutation spectrum for non-syndromic autosomal recessive deafness 2.

Objective:To explore the measures for prevention of pneumothorax in CT-guided thoracic sympathetic block.Methods:The clinical data of 769 patients with hyperhidrosis or Raynaud syndrome treated with CT-guided chemical destructive block of thoracic sympathetic nerve chain in Jiaxing First Hospital from January 2010 to December 2017 were retrospective analyzed. The CT-guided thoracic sympathetic nerve block puncture was performed with a special blunt needle outside the wall pleura above the caput costae following the principle of "safe distance" and "advance only". After exclusion of pneumothorax by CT scan, 2.5 ml of absolute ethanol mixed with 30% iohexol 0.25 ml was injected on both sides of thoracic sympathetic nerve chain.Results:The punctures were successfully performed in all 769 patients (1 538 nerve chain segments) and no pneumothorax occurred. After treatment with absolute ethanol injection, Horner syndrome occurred in 31 patients, which disappeared after injecting saline into the stellate ganglion; and intercostal neuralgia occurred in 188 patients after surgery, which was healed in 1 to 3 months.Conclusion:It is suggested that pneumothorax can be avoided through CT guidance, using appropriate needles and puncture techniques during the procedure of thoracic sympathetic nerve chain block.
