Objecteve To study the relation between the enhanced CT image parameters and metastasis, type of peripheral lung cancer. Methods The enhanced CT image parameters of 138 peripheral lung cancers confirmed by pathology were analyed retrospectively. Both plane scan and contrast-enhanced CT were performed in all the patients, and boundary CT value of each lung cancer was measured. Results Contrast-enhanced CT showed that peripheral lung cancer had big and bent peripheral vessels, and the peripheral density of tumor mass was correlated with its metastasis. The frequency of adenocarcinoma metastasis was higher than that of squamous carcinoma. Conclusion Contrast-enhanced CT was helpful for predicting the latent possibility of peripheral lung cancer metastasis.

Purpose To implement lower artery angiography in patients with peripheral arterial occlusive disease, and to investigate the feasibility of lower extremity gemstone spectral CT angiography in improving image quality.Materials and Methods Forty-eight patients suspected with lower extremity arterial occlusive diseases were randomly divided into research group and control group. Research group (24 cases) were carried out gemstone spectral CT angiography (CTA) scan and control group (24 cases) were scanned with multi-slice spiral CT (CTA). The CT value of the common iliac artery, popliteal artery and its branches was measured and contrast to noise ratio (CNR) were calculated in both groups. The images were evaluated independently by 2 senior physicians based on a 5-level evaluation standard.Results The CT value of common iliac artery, popliteal artery, anterior tibial artery and the CNR in research group were all higher than those in control group (t=8.7, 7.9, 12.6 and 17.2,P<0.01), but the background noise was lower than that in control group (t=1.5,P<0.01). The scores of two image quality accessed by physician 1 and 2 were 110:90 and 111:93 respectively with statistical difference (Z=-7.6 and-8.0, P<0.01).Conclusion The image obtained by gemstone spectral CT optimal single energy image technique is much better than that by conventional multi-slice spiral CT in lower extremity angiography.

Objective To inquire into the location of the relevant gene mutations in the Chinese familial hypokalaemic periodic paralysis, and to specify the correlation between the genotype and the clinical features of this disease. Methods Target-exon PCR and DNA direct sequencing were used to research the mutations in the CACNA1S, SCN4A, and KCNE3 genes of 14 familial hypokalaemic periodic paralysis probands. If a positive member was found, the other members of his (her) family must be inspected with the sequencing method. Results The probands of 3 families showed the known correlating mutations of hypokalaemic periodic paralysis, which were R1239H mutations in the CACNA1S in 1 family and R672H mutations in the SCN4A in the other 2 families. In addition, the differences of the age of onset, the responsibility to the treatment with acetazolamide and penetrance were found between the CACNA1S R1239H and SCN4A R672H mutations. Conclusions SCN4A R672H and CACNA1S R1239H mutations exist in the Chinese familial hypokalaemic periodic paralysis. Differences of the clinical features exist, resulting from these 2 kinds of mutations.

AIM: To study the protective effects of the extract of Ginkgo biloba (EGB) on brain tissues in experimental diabetic rats and explore its possible mechanisms. METHODS: Thirty male Sprague-Dauley rats were divided into three groups: normal control group, diabetic group and EGB-treated group. Strepozotocin were injected intraperitoneally on the later two groups to induce diabetes, EGB-treated group was injected intraperitoneally with EGB, and the others were treated with normal saline at the same volume. After five weeks, the content of endothelin (ET), malondial dehyde (MDA), NO2~-/NO 3~-, and the activity of superoxide dismutase (SOD), nitric oxide synthase (NOS) were determined in brain homogenate, and the level of blood glucose, insulin and ET were measured respectively. In addition, the morphologic changes of the brain tissue were studied by light microscopy and electron microscopy, respectively. RESULTS: In diabetic group, there were degeneration of neuron, brain edema, softened focus and demyelination in the white matter of brain by light microcopy. There were expansion of mitochondria of neuron and gliocyte, the shortened of crista, demyelination of neurofiber and injury of blood-brain-barrier by the electron microscopy. After treated with EGB, the pathological changes decreased in brain under light microcopy and electron microcopy. Compared with diabetic rats, the activity of SOD and the level of serum insulin increased, while the level of blood ET, the activity of NOS, the content of ET, MDA, NO2~-/NO3~- decreased in EGB-treated rats (P

Objective To evaluate the effect of preoperative transarterial chemoembolization (TACE) for resectable hepatocellular carcinoma (HCC).Methods HCC patients undergoing up-front hepatectomy (group A) were compared with those receiving TACE before hepatectomy (group B).Results Tumor size decreased significantly after TACE (t =3.3 1,P =0.021).The rates of tumor encapsulation and liver adhesions were significantly more often seen in group B.There were fewer tumor-residual and more frequent necrosis in group B.Operative time in group B was longer (t =2.71 ,P =0.046).The average blood loss and complication rate were of no difference between the two groups.The occurrence of pleural effusion and intrahepatic recurrence rate in group A was higher than group B (x2 =3.85 ,P =0.031) (x2 =2.76,P =0.046).The overall survival rate from the second year postoperative in group B was higher than group A (x2 =3.37, P =0.043).Conclusions TACE could diminish tumor, advance encapsulation and reduce tumor-residual.Preoperative TACE does not improve 1-, 2-, and 3-year tumor-free survival rates but improve 1-, 2-, and 3-year overall survival rates.

Objective To investigate the clinical value of cardiopulmonary resuscitation (CPR) with abdominal lifting and compression on patients with breathing and cardiac arrest induced by severe chest trauma.Methods Sixty-six breathing and cardiac arrest patients induced by severe chest trauma admitted to the General Hospital of Jingyuan Coal Industry Group Company from October 2011 to October 2016 were enrolled,and they were divided into abdominal lifting and compression group (n =32) and unarmed abdominal compression group (n =34) by random number table.The patients in both two groups were given the airway open,respiration support,defibrillation treatment,venous access establishment,vasoactive drugs application and other conventional treatments.On the basis of the routine treatment,the patients in abdominal lifting and compression group were given application of abdominal lifting and compression device with 100 times/min frequency and continuously alternating press down to lift the abdomen,the amplitude of pressing and pulling were 3-5 cm below or above the original level of the abdomen.Those in unarmed abdominal compression group were given abdominal CPR pressing method by hand,the frequency of pressing and depth of subsidence was the same as abdominal lifting and compression group.Heart rate (HR) and arterial blood gas at 30 minutes after CPR as well as the success rate of resuscitation were compared between the two groups.The changes in HR,mean arterial pressure (MAP) and pulse oxygen saturation (SpO2) before and 30 minutes and 60 minutes after CPR were dynamically observed in patients with restoration of spontaneous circulation (ROSC) after abdominal lifting and compression CPR treatment.Results Compared with the unarmed abdominal compression group,HR (bmp:136.13±6.14 vs.148.45±5.16) and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg =0.133 kPa):48.51 ±2.60 vs.62.51 ±2.50] at 30 minutes after CPR in abdominal lifting and compression group were significantly lowered,and arterial partial pressure of oxygen (PaO2) was significantly increased (mmHg:88.07±3.92 vs.74.12±2.12,all P ＜ 0.05).Four patients with ROSC were found in abdominal lifting and compression group,and 2 in unarmed abdominal compression group.The success rate of resuscitation in abdominal lifting and compression group was significantly higher than that of unarmed abdominal compression group (12.50％ vs.5.82％,P ＜ 0.05).In 4 patients with ROSC after abdominal lifting and compression CPR showed a downward trend in HR and an upward trend in MAP and SpO2 with CPR time prolongation.Conclusions The effect of abdominal lifting and compression CPR is better than that of unarmed abdominal compression CPR,which is of great value for the life saving of patients with breathing and cardiac arrest induced bv severe chest trauma.

Chronic kidney disease (CKD) is becoming a global social problem. It is important to slow down the progression of CKD for economic and social concerns. In recent years, it has been found that colon is one of the vital organs which produce uremic toxins. And enterogenous uremic toxins are closely related to the prognosis of CKD. Theory of gut-kidney axis for the slowdown of CKD progression was raised by foreign scholars and became the research hot spot. Colon therapy with traditional Chinese medicine (TCM) has been widely used in clinical practice and is believed to slow down the progression of CKD by numerous clinical reports. However, low re-search quality and ambiguous results limited its further application. Under the guidance of senior TCM Professor Huang Chunlin, who emphasized the method of draining turbidity through bowels in the management of CKD, from the Nephrology Center, Guangdong Provincial Hospital of Chinese Medicine, as well as the modern theory of gut-kidney axis, we had carried out a series of exploratory researches which will provide data and methodology support for further confirmatory studies and improve its effectiveness.
