The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

Double aortic arch with an atretic left arch distal to the origin of left subclavian artery was diagnosed with multi-detector row computed tomography (MDCT) in two children with dysphagia. This rare type of complete vascular ring is clinically important because it may be confused with right aortic arch in mirror imaging. Anatomic details of this rare type of complete vascular ring demonstrated on MDCT facilitated appropriate surgical treatment.

OBJECTIVETo evaluate the accuracy of Hadeco ES-1000spm hand-held doppler during the anterolateral thigh (ALT) flap harvest.

METHODSTwenty-five patients (26 sides) with ALT flaps for head and neck reconstruction between May 2005 and May 2010 received preoperative Doppler examination for the location of the cutaneous perforators of ALT flaps. The Doppler signals and body mass index (BMI) were recorded preoperatively according to ABC system. The locations of Doppler signals and of the actual cutaneous perforators at surgery were plotted and compared. The diameter of perforators was measured.

RESULTSOne to three cutaneous perforators of the ALT flap were consistently found at specific locations. They were named perforators A, B, C from proximal to distal. Perforators A, B and C were present in 15 (58%), 24 (92%) and 20 (77%) cases and the diameter (> 0.5 mm) of A, B and C were 11/15, 22 (92%) and 8 (40%) respectively. The Doppler signal was within 0.5 cm of the actual perforator location in 85% flaps. The accuracy of Doppler decreased with increase of BMI.

CONCLUSIONSPreoperative assessment by hand-held Doppler is useful in predicting the perforator vessels' locations and diameter although it's accuracy is limited.

OBJECTIVETo analyze and compare the characteristics of musculoskeletal ultrasonography and X-ray of knee osteoarthritis, and to investigate the advantages of them.

METHODSAccording to the inclusion and exclusion criteria, 57 cases (66 knees) were collected from February 2015 to May 2015. Among them, there were 48 females and 9 males with an average age of (58.9 +/- 9.8) years old (ranged, 41 to 78 years old). The main symptoms included unilateral or bilateral knee pain and locked joints explicit areas of tender points. The mean course of disease was (13.6 +/- 3.0) months. The results of musculoskeletal ultrasound and X-ray examinations were analyzed.

RESULTSAccording to Kellgren-Lawrence classification of knee joint on the X-ray: the musculoskeletal ultrasound results of patients with I degree synovial hyperplasia in 9 cases, joint effusion in 20 cases, meniscal disease in 13 cases, patellar pad inflammation in 5 cases, and patellar lesion in 8 cases. The musculoskeletal ultrasound results of patients with III degree: synovial hyperplasia in 20 cases,joint effusion in 31 cases, meniscal disease in 22 cases, patellar pad inflammation in 16 cases and patellar lesion in 17 cases. The musculoskeletal ultrasound results of patients with III degree: synovial hyperplasia in 6 cases,joint effusion in 6 cases, meniscal disease in 7 cases, patellar pad inflammation in 7 cases and patellar lesion in 5 cases.

CONCLUSIONThe musculoskeletal ultrasound can detect the pathological changes of knee soft tissue sensitively, provide an accurate location of lesions,and find lesions early. The musculoskeletal ultrasound should be applicated in the diagnosis of knee osteoarthritis.

OBJECTIVETo explore the expression of uncoupling protein-2 mRNA in brown adipose tissue, white adipose tissue and skeletal muscle of diet-induced obesity-resistant (DIO-R) rats.

METHODSFifty male Sprague-Dawley (SD) rats were randomly divided into a control group and a high-fat group and fed with basic diet and high-fat diet respectively for 13 weeks. DIO-R and DIO rats were selected according to their body weight. The change of body weight and the intake of total calorie were observed. Reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the expression of UCP2 mRNA in rat.

RESULTSBody weight and total calorie intake in DIO-R rats (425.1 +/- 27.1) g, (31,693 +/- 946) kJ were significantly lower than those in DIO rats (489.7 +/- 20.5) g, (34,363 +/- 1465) kJ. The peak area of UCP2 mRNA in white adipose tissue in DIO-R rats was 352 +/- 30 and in DIO rats was 101 +/- 12. The peak areas of UCP2 mRNA in skeletal muscle in DIO-R and DIO rats were 130 +/- 15 and 170 +/- 12, respectively. The peak areas of UCP2 mRNA in brown adipose tissue of DIO and DIO-R rats were 124 +/- 14 and 147 +/- 19, respectively.

CONCLUSIONThe expression of UCP2 mRNA in white adipose tissue of DIO-R rats increased significantly. These results suggest that obesity-resistance was associated with a tissue-specific increase in UCP2 expression.

OBJECTIVETo introduce a method of functional reconstruction for total lower lip defects.

METHODSSix patients with lower lip cancer were treated by surgery from November 2007 to February 2009. The full thickness defects with a size from eighty percent to total lower lip were reconstructed with two triangular mental neurovascular island flaps of chin. The musculocutaneous and mucous flaps with neurovascular pedicles were advanced in a V-Y manner to close the defect and reconstruct the orbicularis oris muscle.

RESULTSAll flaps survived and no recurrence and complication were observed and showed excellent cosmetic and functional results over 6 months of follow-up. The reconstructed lower lips provided a wide-enough mouth opening, and the sensation of oral mucosa and the muscle function of oral sphincter were preserved.

CONCLUSIONSThe technique of mental neurovascular V-Y advancement island flap can get satisfactory results in both functional and the aesthetic perspects.

OBJECTIVETo explore the relationship between the polymorphism of TNF-α gene 308, 238 locus and the susceptibility to pneumoconiosis.

METHODSEighteen published case-control studies about TNF-α gene 308, 238 locus polymorphism and pneumoconiosis susceptibility were searched out from sino-foreign databases from January 1994 to December 2010. Meta-analysis was applied on the published research to calculate the pooled OR value (95%CI) and stratified analyze the types and species of pneumoconiosis.

RESULTSEleven of the published research articles were selected into the analysis, including 10 research focusing on TNF-α gene 308 locus, with 1408 cases and 1639 controls in total. The meta-analysis showed that comparing with Gln/Gln carriers, Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were 1.89-fold (95%CI: 1.10 - 3.24), 1.53-fold (95%CI: 1.25 - 1.87), and 1.56-fold (95%CI: 1.28 - 1.90) more susceptible to pneumoconiosis, respectively. The stratified analysis showed that among coal workers, the TNF-α gene 308 locus Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were separately 2.29-fold (95%CI: 1.22 - 4.29), 1.56-fold (95%CI: 1.20 - 2.03), 1.64-fold (95%CI: 1.28 - 2.11) more susceptible to pneumoconiosis than Gln/Gln carriers; and among Asian people, the TNF-α gene 308 locus Gln/Arg, Gln/Arg + Arg/Arg carriers were separately 1.58-fold (95%CI: 1.28 - 1.95) and 1.57-fold (95%CI: 1.28 - 1.94) more susceptible to pneumoconiosis than the Gln/Gln carriers. Four case-control research focus on the study of TNF-α gene 238 locus, including 391 cases and 391 controls in total. The analysis showed that comparing with the non-carriers, TNF-α gene 238 locus Arg/Arg, Arg/Gln, Gln/Arg + Arg/Arg carriers were 6.03-fold (95%CI: 1.35 - 26.97), 1.87-fold (95%CI: 1.07 - 3.30) and 2.36-fold (95%CI: 1.37 - 4.07) more susceptible to pneumoconiosis.

CONCLUSIONTNF-α gene 308, 238 locus Arg/Arg, Gln/Arg, Gln/Arg + Arg/Arg carriers are more susceptible to pneumoconiosis.

OBJECTIVETo explore the DNA methylation levels of genome in cFb transdifferentiation induced by SiO2 in rats.

METHODSThe primary macrophages and fibrocytes of SD rats were co-cultured directly and indirectly, which were exposed to SiO2 at the doses of 25, 50 and 100 g/ml. The transdifferentiation of cFb was identified with immunohistochemical assay. The genomic DNA methylation levels of cFb were detected with HPLC.

RESULTSUnder the condition of indirect co-culture, as compared with control group, the genomic DNA methylation levels of cFb exposed to SiO2 at the doses of 25, 50 and 100 g/ml reduced by 19.9%, 26.9% and 30.3%, respectively (P < 0.05); as compared with cFb exposed to 100 g/ml SiO2, the genomic DNA methylation levels of cFb exposed to 5-aza-dC decreased by 22.0% (P < 0.05). Under the condition of ThinCert(TM) direct co-culture, as compared with control group, the genomic DNA methylation levels of cFb exposed to SiO2 at the doses of 25, 50 and 100 g/ml reduced by 22.2%, 30.2% and 36.7%, respectively (P < 0.05); as compared with cFb exposed to 100 g/ml SiO2, the genomic DNA methylation levels of cFb exposed to 5-aza-dC decreased by 20.6% (P < 0.05).

CONCLUSIONUnder the co-culture condition in vitro, SiO2 could reduce the genomic DNA methylation levels of cFb. The ThinCert(TM) direct co-culture can be used to study the silicosis fibrosis.
