This study was aimed to observe the clinical curative effect of Thesium Chinese tablets in the treatment of chronic bronchitis (syndrome of phlegm heat in the lung). A total of 100 cases of chronic bronchitis (syndrome of phlegm heat in the lung) were randomly divided into two groups. The control group was treated with anti-inflamma-tion, relieving cough and asthma, phlegm removing and oxygen inhalation, maintenance of water electrolyte balance and other symptomatic treatment. In the treatment group, on the basis of treatments in the control group, Thesium Chinese tablets were given at the dosage of 1.6 geach time, 3 times a day. Both groups were treated for 1 course of 10 days. The results showed that clinical symptoms and traditional Chinese medicine (TCM) syndromes of quantizing integral were improved after treatment in both groups. And the therapeutic effect of treatment group was significantly better than the control group (P< 0.01). Thesium Chinese tablets can effectively shorten the time of clinical symptom improvement time, obviously improve the level of Ig among elderly patients with acute exacerbation of chronic bron-chitis, and enhance the immune function. It was concluded that the Thesium Chinese tablets can effectively improve the quality of life among patients with chronic bronchitis (syndrome of phlegm heat in the lung).

OBJECTIVE: To evaluate the age, sex, etiology, diagnosis and treatment time of nasal bone fractures. METHOD: Clinical data of 202 cases with nasal bone fractures treated in the hospital were retrospectively analysed. RESULT: A total of 202 cases,163 men (80. 7%) and 39 women (19. 3%). Fifty-two patients had a relationship with alcohol consumption, and all of them were males. The most frequent reasons of the injury were fight 46. 5% (94 cases) followed by falling-down 21. 3% (43 cases), traffic accidents 19. 3% (39 cases), works related 6. 5% (13 cases), sport injuries 5. 9% (12 cases) and others 0. 5% (1 cases). Patients distribution in seasons were: spring 54 cases (26.7%), summer 42 cases (20.8%), autumn 58 cases (28.7%), winter 48 cases (23. 8%). Diagnosis of nasal bone fractures were made positively by x-ray films in 79. 7% of cases, but 100% by CT. Positive predictive value of CT was superior to that of X-ray films in the diagnosis of nasal bone fracture. CONCLUSION High morbidity of nasal bone fracture was seen in the age group of 20-29 years, and predominantly in male. Fight was found to be the main etiologic factor. We think that CT is necessary for diagnosing nasal bone fracture.

Objective To detect the expression level of Ang-1, Ang -2 and Tie-2 receptor mRNAs in the hemangioma tissuses and to explore the effects of Ang-1, Ang-2, and Tie-2 receptor on the angio-genesis in the hemangioma. Methods By use of semiquantinative reverse transcription polymerase chain reaction, we detected the expression level of Ang-1 mRNA, Ang-2 mRNA and Tie-2 mRNA in 30 cases of hemangioma (17 specimens of proliferating hemangioma, and 13 involuting hemangioma )together with 10 cases of normal skin as control, and the expression level of Ki-67 protein was also detected by an im-munohistochemica method. Results The expression of Ang-2 mRNA and Tie-2 mRNA in the prolifera-ting hemangiomas was higher than that in involuting hemangiomas (P<0.01) . The expression of Ang-1 mRNA in hemangiomas was negative. Conclusion The unbalance of Ang-Tie-2 system is probably impor-tant for the pathogenesis and development in hemangiomas.

Objective · To observe the vascular structure before autogenous arteriovenous fistula (AVF) construction in patients with end-stage renal disease (ESRD) and analyze the risk factors of the pre-existing venous neointimal hyperplasia. Methods · The 8 vein samples were screened from 20 ESRD patients at their first time of the AVF construction (non-stenosis group), and the other 8 vein samples were screened from 15 ESRD patients at their at least second time of the AVF repair operation (stenosis group). Sections were prepared and stained with hematoxylin & eosin (H-E) or Masson's trichrome for observation. The intimal thickness was measured by the cellSens software, and its correlation with patients' renal function, calcium-phosphorus metabolism, iron metabolism and inflammatory reaction in the non-stenosis group were analyzed. Results · In the non-stenosis group, there were varying degrees of intimal hyperplasia in 5 (62.5%) cases, loss of endothelial cell layer in 3 (37.5%) cases, and vascular wall replacement by collagenous with atrophy or loss of muscle layer in 5 (62.5%) cases. In the stenosis group, almost all vein samples showed general thickening of the wall and 2 (25.0%) totally lost the muscle layer. Avg It of those two groups were statistically significant (P<0.01). In the non-stenosis group, both of average I/M thickness and average I/M area were negatively related to glomerular filtration rate (GFR) (P<0.05) and positively related to serum phosphorus and calcium-phosphorus product (P<0.05). Conclusion · Some apparently normal vein of ESRD patients showed varying degrees of intimal hyperplasia before AVF construction. The intimal hyperplasia had a remarkable correlation with GFR or calcium-phosphorus metabolism. Early intervention of the intimal hyperplasia prior to AVF construction may be a new prevention and control means.

Objective To investigate the status of fatigue and depression and their influencing factors in patients with acute coronary syndrome, and analyse the correlation of fatigue, depression and self-management behavior. Methods 113 patients were investigated by using Fatigue Symptom Inventory (FSI), Patient Health Questionnaire-9 (PHQ-9), Coronary artery disease Self-management Scale (CSMS). Results The score of fatigue was (4.59±1.93)points, while depression scored (5.05±1.48)points and self-management behavior scored (57.29 ±8.29)points; the score of fatigue, depression of female patients were higher than that of male patients, which had statistical difference(t=2.535-5.894, P<0.05);Regression analysis showed that gender, time of illness, number of other chronic diseases were major factors affecting fatigue while gender and treatment method were major factors affecting depression; there were negative ralationships between self-management and fatigue, self-management and depression (r=-0.855-0.682). Conclusions Fatigue, depression are common in patients with acute coronary syndrome, and can affect their self-management behavior, and the female patients are more susceptible to fatigue and depression.

Objective To compare HER-2 state in breast cancer tissue deteced by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) and analyze their correlation. Methods HER-2/neu protein expression and gene amplification were detected by FISH and IHC in 56 newly-diagnosed cases of female breast cancer from July 2008 to July 2009. Results Of the 56 patients, HER-2 protein expression (-), (+), (++), (+++) was 9 cases (16.1%), 29 cases (51.8%), 11 cases (19.6%) and 7cases (12.5%) respectively; 26 cases (46.4%) had HER-2 gene amplification while 30 cases (53.6%) didnt have. Type of HER-2 gene amplification was mainly HER-2(++) and HER-2(+++), and according gene amplification rate was 72 7% and 100%. HER-2 (+) gene amplification rate was 37.9 %(11cases) and no gene amplification was found in HER-2(-) tissue. The HER-2 positive rate using two methods had significant difference(χ2=19.778,P<0.01). HER-2(-) and HER-2(+++) had good consistency with the FISH results(Kappa=0.969),but HER-2(+) and HER-2(+ +) were poorly consistent with the FISH results(Kappa=0.271). Conclusions IHC is the preliminary screening method for detection of HER-2 expression. HER-2(-) and HER-2(+++) have good consistency with the gene amplification, and can guide clinical treatment. Some patients with HER-2(+) and HER-2(++) have HER-2 gene amplification. FISH is needed for targeted therapy.

BACKGROUND: Currently, the widely used intervertebral disc degeneration models are induced by altering intervertebral disc biomechanics, damaging intervertebral disc structure or changing hereditary features with genetic technique. All these methods are vades from natural duration of intervertebral disc degeneration. OBJECTIVE: To evaluate the feasibility of the establishment of rabbit model of ischemic lumbar vertebrae adjacent to endplate by percutaneous puncture followed by pingyangmycin injection. METHODS: A total of 46 New Zealand white rabbits were selected and two vertebraes were divided as experimental group (L_5) and control group (L_4) in every rabbit. Vertebrae adjacent to endplate was punctured. Pingyangmycin (2 g/L) 1 mL was injected into rabbits in the experimental group. And 1 mL normal sodium was injected into the control group. Lumbar artery angiography was performed in 4 rabbits before operation. Six rabbits were randomly performed MRI and then were executed for vertebral histology at weeks 1,2, 3, 4, 5 and months 2, 3 after operation. Ischemic areas of L_5 were measured by the MRI and histological section at week 4 after operation. RESULTS AND CONCLUSION: MRI and histology of control group had not specific changes. MRI had not significant signal intensity changes in the first 2 weeks in the experimental group. At week 3 after operation, it demonstrated slightly hyperintense signal on T_2-weighted image (T_2WI) and fat-suppression T_2-weighted image (FS T_2WI), while fat-suppression T_1-weighted image (FS T_1WI) was hypointense signal. The signal changed more obviously at week 4. Histology of experimental group had not specific changes in the first 2 weeks. From weeks 3-4, bone trabecula arranged confusedly and disorderly, with gradually decreased osteocyte and marrow haemocytes, while adipocytes increased and coalesced. Cartilage corpuscle of endplate decreased and architecture became disorder. But the anulus fibrosus and nucleus pulposus had no obviously changes. The intervertebral disk of the experimental group degenerated at week 5, and the ischemia of lumbar vertebrae still existed and intervertebral disk degenerated more obviously at months 2-3 after operation. There was significant positive correlation of ischemic areas of experimental group between MRI and histology at week 4 (t-=0.965, P < 0.001). The rabbit model of ischemic lumbar vertebrae adjacent to endplate can be established successfully by peroutaneous puncture vertebrae adjacent to endplate followed by pingyangmycin injection. The operation is minimally invasive, simple and reproducible, with high success rate. This is a fairly ideal animal model to study the degeneration of the lumbar spine and intervertebral disc.

Digital polymerase chain reaction ( PCR) has been experiencing a rapid development during the past few years. Comparing with the traditional real-time quantitative PCR ( RT-qPCR) , using the same primer and probe, the accuracy for the absolute quantification of target gene is significantly improved. The development of digital PCR is directly related to the development of microfluidics. The integrated fluid circuit is an early combination of the microfluidics and digital PCR, which has a complicated fabrication process with high cost. Recently, researchers are trying to apply the droplet microfluidics in digital PCR, and the droplet microfluidic chip is able to generate millions of droplets within a short time. Each of these droplets containing no more than one target gene is a reaction chamber during the amplification process. After amplification, each droplet is tested to achieve the absolute quantification of the target gene. This paper reviews the recent progresses of droplet digital PCR, and the applications of droplet digital PCR in biological, medical and environmental fields.
