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.

Objective To find a better method to reconstruct total ear in one stage. Methods In the procedure, a compound framework was formed, in which Medpor acted as ear framework and homogenous rib cartilage as helix-framework after being sculptured, then they were vamped together. The formed framework was covered with adjacent skin flap and homogenous skin graft after it had been covered with superficial temporal fascia flap. Results From January 2001 to Augest 2003, 8 cases of congenital microtia or antotia were treated in this way, and all of them obtained satisfactory appearance in auricle. Conclusion The reconstructed ear has a delicate structure and good appearance, and looks and feels as a real one by this new procedure.

Objective To analyze the clinical value of Guizhi Fuling capsules combined with fosfomycin trometamol power in the treatment of pelvic inflammatory disease and pelvic effusion.Methods A total of 60 patients with pelvic inflammatory disease and pelvic effusion from February 2013 to March 2016 in our hospital were selected and divided into the control group and the observation group , 30 cases in each group.The control group were treated with fosfomycin trometamol power, and the observation group were additionally treated with Guizhi Fuling capsules.The therapeutic effects and changes of TCM syndrome scores were compared between the two groups.The levels of serum C reactive protein ( CRP ) in the two groups were determined before and after treatment and the ultrasound examination was performed and changes of pelvic effusion diameter was determined before and after treatment.Results The total effective rate of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05).There was no significant difference in TCM syndrome scores between the two groups before treatment .After treatment, the TCM symptom scores of both groups were decreased, the difference was statistically significant ( P<0.05 ) .The scores of lumbosacral swelling pain, abdominal pain, morbid leucorrhoea increase, fatigue, low-grade fever and soreness of waist in the observation group were lower than those in the control group, the difference was statistically significant (P<0.05).Before treatment, there was no statistically significant difference in pelvic effusion and CRP levels between the two groups.After treatment, the pelvic effusion diameter and CRP levels were decreased, the difference was statistically significant (P<0.05), and those in the observation group were lower than the control group, the difference was statistically significant (P<0.05). Conclusion Guizhi Fuling capsules combined with the fosfomycin trometamol power is significantly effective in the treatment of pelvic inflammatory disease and pelvic effusion.It can significantly reduce the inflammatory reactions of patients, and improve the TCM syndrome scores.

Objective To observe the therapeutic effect of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease and its influence on high sensitivity C - reactive protein (hs-CRP). Methods 106 cases of patients with chronic pelvic inflammatory disease were selected to be divided into the observation group and control group with each group of 53 patients. The patients in control group were only given clarithromycin, on the base of control group, patients in observation group were given Cassia Twig-Poria Cocos. Both group were treated for three courses of 7-14 days. Then the therapeutic effect, adverse reactions, hs-CRP, erythrocyte sedimentation rate and hematocrit of patients were investigated. Results The total effective rate of patients in observation group was 90.57%, and the control group was 75.47%. The total effective rate of observation group was higher than control group with statistically significant difference (P<0.05). The hs-CRP, erythrocyte sedimentation rate and hematocrit of two groups both decreased after treatment (P<0.05) and these indexes of observation group was much less than control group (P<0.05). Besides, there was no difference of incidence of adverse reactions between two groups during the treatment. Conclusion Treatment of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease not only can lessen inflammatory reaction, but also can improve the therapeutic effect effectively.

OBJECTIVE:To evaluate the bioequiavailability of two kinds of loratadine tabletes in Chinese healthy volunteers.METHODS:A single oral dose 40 mg of two loratadine preparations(reference and test preparations)was given to 20 volunteers(whom were divided into two groups)in a randomized cross-over study.The concentration of loratadine in plasma was determined by solid phase extraction-HPLC.RESULTS:The main pharmacokinetic parameters of reference and test preparations were as follows:Cmax were(17.00?3.90)and(18.41?2.58)?g?L-1;tmax were(1.06?0.25)and(0.93?0.20)h;t1/2Ke were(1.34?0.38)and(1.08?0.38)h;AUC0～∞ were(37.41?17.38)and(36.38?16.73)?g?h?L-1;AUC0～8 were(35.11?15.72)and(34.76?15.34)?g?h?L-1,respectively.The relative bioavailability of the test preparation was(99.0?18.7)% as against the reference preparation,and no significant differences was noted for the two formulations in ANOVA and two-one side t test.CONCLUSION:The two formulations were bioequivalent.

One leading research target of modern tumor radiotherapy is to increase radiosensitization of tumor and improve curative effect of radiotherapy.Histone deacetylase inhibitors are epigenetic drugs that can play a part in radiosensitization through means of induction of apoptosis,inhibition of repair of DNA doublestrand breaks,cell cycle arrest,improvement of tumor cell hypoxia and increase of reactive oxygen species.There is an urgent need to develop biomarkers based on these pathways,which can promote clinically individualized treatment.

Objective From the angle of skeletal muscle ultrastructure and free radical metabolism,the paper explored the effect of vitamin E on skeletal muscle's damage after eccentric exercise.Methods 48 male Sprague Dawley rats were randomly divided into the control group,the sport group,the physiological saline group,and the vitamin E group.The model of animals was made by a bout of eccentric exercise on a treadmill.After the training,triceps brachiies were extracted from the right side of rats.Parts of triceps brachiies were made for microelectric slices,the others for the extracting of SR by the method of centrifugation at different speeds and for measuring the content of MDA and activity of SOD.Results In the vitamin E group,the muscular ultrastructures damage were improved obviously compared with that of the physiological saline group.Meanwhile,the value of MDA in the vitamin E group was greatly decreased and activity of SOD was notably increased compared with the sport group and the physiological saline group,but still worse than those of the control group.Conclusions Supplying of vitamin E could decrease the content of MDA in SR of skeletal muscle,increase the activity of SOD,then further relieve the effect of free radical on athletic injury.

Lung cancer is the main cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) accounts for about 80% of lung cancer cases, but only 25%-30% of initially diagnosed patients have the option of radical surgery because of the lack of effective measures for early diagnosis. For locally advanced and advanced NSCLC, radiotherapy alone or comprehensive treatment with chemoradiotherapy is the main treatment method; however, the curative effect is unsatisfactory. Recently, increasing evidence sug-gests that targeted drugs, such as epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), combined with radiotherapy/chemoradiotherapy represent a promising treatment modality for NSCLC. This review will discuss the research status of EGFR-TKIs and radiotherapy for locally advanced and advanced NSCLC.

OBJECTIVE:To provide reference for rational use of recombinant human granulocyte-colony stimulating factor (rhG-CSF) in cancer patients. METHODS:Referring to the expert advice and guideline of clinical application of rhG-CSF at home and abroad,DUE criteria on rhG-CSF for cancer patients was established;questionnaire was designed,and the medical re-cords of rhG-CSF in a third grade class A hospital was evaluated. RESULTS:The DUE criterion on rhG-CSF for cancer patients included 3 parts,such as drug indications,the course of medication and medication results,14 items in total. Through the imple-mentation of DUE,retrospective evaluation of 220 medical records showed that the application of rhG-CSF was up to the stan-dard in respects of drug indications,no contraindication,routine blood test and drug interaction monitoring at least twice every week,there still was irrational phenomenon. CONCLUSIONS:The established DUE criterion on rhG-CSF for cancer patients is with the characteristics of definite content,target and paracticabilitg,which can provide reference for the work development of clinical pharmacists.

Objective To observe the effect of a rotating magnetic field in preventing and treating irradiation-induced esophagitis in rats. Methods Forty female Wistar rats were randomized into 5 groups:a non-irradiated control group,an irradiation group,an amifostine treatment group ( amifostine group ),a 90 min magnetic field treatment group (90 min magnetic group) and a 120 min magnetic field treatment group ( 120 min magnetic group),with 8 rats in each group.The esophaguses of all rats except those in the control group were exposed to a single irradiation with 6 MV X-rays from a linear accelerator at a dosage of 43 Gy.Four rats in each group were randomly chosen to be observed 1 and 2 weeks after the irradiation.Blood cytokines were detected in their arterial blood.Any pathological changes of the esophagus were observed with HE staining under a light microscope at the same time. Results Irradiation-induced esophagitis was observed in the irradiation group 7 days after irradiation,with obvious exfoliation and necrosis of the esophagal epithelium mucosae.The submucosa were hyperaemic and dropsical with abundant inflammatory cell infiltration.The pathological changes of the esophagus were similar at 7 and 14 days after irradiation.However,the irradiation-induced esophagitis of rats in the amifostine group,the 90 min magnetic group and the 120 min magnetic group were relatively slighter and the blood leucocytes and neutrophis in those 3 groups were significantly lower than those in the irradiation group,while a tendency toward repair of the mucosa of the esophagus was detected.Serum TNF-α,IL-1 and IL-6 in the 90 min magnetic group and 120 min magnetic group were significantly lower than those in the irradiation group. Conclusions Both a rotating magnetic field and amifostine can help prevent and treat irradiation-induced esophagitis.Their therapeutic efficacy is similar.Exposure to a rotating magnetic field could inhibit the expression of inflammatory factors,and thus lessen the inflammatory reaction of acute irradiation-induced esophagitis.
