China Medical Equipment 2017;14(2):31-34
Objective:To discuss the clinical value of CT-guided interstitial implantation of125I radioactive particle through the percutaneous puncture in the treatment of central-type lung cancer.Methods: 63 patients with the central-type lung cancer treated in Renmin Hospital of Wuhan University from November 2013 to July 2016 were randomly grouped (31 cases in the control group and 32 cases in the observation group). Patients in the control group were given the treatment of bronchial arterial perfusion with the chemotherapeutic drugs; while patients in the observation group were given the CT-guided interstitial implantation of125I radioactive particle through the percutaneous puncture. The clinical therapeutic effect and complications were observed of the two groups and the quality of life scores before and after the treatment were summarized between two groups as well.Results: The overall effective rate of observation group was 84.38% (27/32) that was higher than 61.29%(19/31) of control group, with statistical difference (x2=4.259,P<0.05); the complication rate of observation group was 9.38% (3/32) that was lower than 12.90% (4/31) of control group, with no statistical difference (x2=0.002,P>0.05); the quality of life score of observation group after the treatment was 84.57±3.27 that was higher than 70.38±3.20 of control group, with statistical difference (t=17.402,P<0.05).Conclusion: CT-guided interstitial implantation of125I radioactive particle through the percutaneous puncture in the treatment of patients with central-type lung cancer has the significant effect, and it can effectively improve the quality of life for patients and have the high degree of safety.
2.Development of the construction and delivery of siRNA
International Journal of Biomedical Engineering 2008;31(2):-
RNA interference(RNAi)is a post-transcriptional gene-silencing phenomenon which is triggered by double-stranded RNA(dsRNA).Attempts age being made to exploit RNAi in a clinical setting.However,before RNAi can be exploited as therepeutically,several obstacles must be overcome such as the efficient and safe delivery of siRNA into target tissues and cells.Any usefull delivery method should be desinged to target siRNA.

SNP may play an important role in the mechanism of sepsis. Detection SNP of the patients with sepsis may be the key point to the individualization treatment in near future.
4.Research progress on biomarkers of coal workers′ pneumoconiosis
China Occupational Medicine 2022;49(2):228-233
Coal workers' pneumoconiosis(CWP)is one of the most common occupational diseases. The pathogenesis of CWP
remains unclear and effective therapeutic drug is not exist. Therefore,looking for CWP-related biomarkers have become a focus
of research. In recent years,intensive studies have been carried out on the pathogenesis of CWP,such as inflammatory
response,alveolar epithelial cell injury,extracellular matrix remodeling,epigenetics,oxidative stress and immune dysfunction.
It has been found that some biomarkers were related to CWP,such as high mobility group protein 1,nucleotide-binding
oligomerization domain-like receptor family protein 3,surfactant protein,mucoprotein 5B,osteopontin,aminin,DNA
methylation,microRNA,long noncoding RNA,cytochrome b-245-alpha polypeptide and cluster of differentiation,and others.
These biomarkers are helpful for early screening,monitoring efficacy and pathogenesis research of CWP. However,it is
necessary to further explore biomarkers with high sensitivity and specificity and conduct prospective clinical value evaluation to
better guide the prevention and treatment of CWP .

Objective: Using MB-80 Microbiology Kinetic Rapid Reader, the methods were established to quantitatively measure the body fluid content of bacterial endotoxin and fungus in infectious patients. Methods: The blood samples were collected from Gram negative bacterial infection and deep mycosis patients and healthy volunteers. After pre-treatment, the plasma samples were measured using MB-80 system through kinetic turbidimetric limulus test method. The system computer could calculate the content of endotoxin and fungus during 1 hour detection. Results: The detection methods of endotoxin and fungus using MB-80 were simple and rapid. The process of pre-treatment was standardized and the results had good repeatability. The normal ranges of plasma endotoxin and fungus of human healthy volunteers were (2.03?2.32)ng/L and (2.46?2.15)ng/L respectively. The plasma endotoxin level of abdominal infection patients was increased significantly to 50-3 958 ng/L. The fungus level of deep mycosis patients was enhanced to 20-2 381 ng/L. Conclusion: The methods of endotoxin and fungus quantitatively measurement by MB-80 are simple and convenient and have results with good repeatability. The new detection methods of endotoxin and fungus can be used for diagnosis of endotoxemia and deep mycosis in early stage of infection.

According to the traditional point of view,CT and lumabar puncture are the main means in the diagnosis of subarachnoid hemorrhage(SAH).The values of conventional MRI T1-weighted imaging(T1WI)and T2 weighted imaging(T2WI)are very little in the diagnosis of SAH.With the development of MRI technique and the research and application of novel MRI sequences,the value of MRI are gradually recognized and affirmed in the diagnosis of SAH.and has shown its superiority.MRI isn't inferior to CT in the diagnosis of acute SAH.evidently superior to CT in the diagnosis of subacute,chronic and atypical SAHs and superior to CT in the diagnosis of the complications of SAH.MRI is valuable in screening for intraeranial aneurysms and postoperative follow-up.

So far, the method of detection of patent foramen ovale (PFO) by transcranial Doppler (TCD) has had two decades of history. Standardization in contrast-enhanced transcranial Doppler US procedures for cardiac right-to-left shunt detection was proposed in the Venice Consensus Paper in 1999, and some questions were raised at the same time. Over the past 10 years, the researchers have conducted a more in depth study on the method. This article reviews the related research progress.

The expression of c-erbB-1 and c-erbB-2 oncoproteins were investigated by immunohistochemical technique using monoclonal antibodies to c-erbB-1 and c-erbB-2 oncoproteins in 43 cases of hasal cell carcinoma (BCC) and 26 cases of squamous cell carcinoma (SCC). The results showed that: ① The expression of c-erbB-1 oncoprotein in BCC increased; the expression of c-erbB-2 oncoprotein in BCC reduced significantly, and lost in 16 cases (16/43). ② The intensities of c-erbB-1 and c-erbB-2 oncoprorein expression had negative and positive correlations to the degrees of SCC differentiation respectively. It is suggested that the abnormal expression of c-erbB-1 and c-erbB-2 oncoprotein in BCC and SCC may play a role in the development of skin tumors.

Objective To investigate the expression of the long non-coding RNA (IncRNA) H19 in the serum of patients with acute pancreatitis and its clinical significance.Methods A total of 82 patients who were diagnosed with acute pancreatitis in Emergency Department and Department of General Surgery in Shenyang Emergency Center from January 2013 to December 2015 were enrolled,and 20 healthy subjects were enrolled as normal controls.Peripheral blood samples were collected from the patients with acute pancreatitis and healthy subjects,the serum was separated,and RNA was extracted.Real-time PCR was used to measure the expression of lncRNA H19,and the correlation between the expression of H19 and other clinical and pathological parameters was analyzed.The t-test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The receiver operating characteristic (ROC) curve was used to evaluate the value of lncRNA H19 in the diagnosis of acute pancreatitis.Results The acute pancreatitis group had a significantly higher H19 expression level in serum than the healthy control group (t =2.364,P =0.020).The severe acute pancreatitis group had higher expression of lncRNA H19 than the mild acute pancreatitis group (t =2.111,P =0.037),and the patients with a Balthazar CT grade above grade C had significantly higher relative expression of lncRNA H19 than those with CT grade ≤ C (t =2.312,P =0.022).The ROC curve showed that H19 measurement helped with the diagnosis of acute pancreatitis with an area under the ROC curve of 0.752 (95% CI:0.636-0.867,P < 0.01).Conclusion Patients with acute pancreatitis have increased expression of IncRNA H19 in serum,and therefore,H19 has certain clinical significance in the diagnosis of acute pancreatitis and the evaluation of disease severity.
