Objective To evaluate the clinical effect of stereotactic radiotherapy in the treatment of lung cancer with superior vena cava syndrome (SVCS). Methods 31 cases of lung cancer with SVCS were treated with body gamma knife. Among them, the diagnosis was confirmed by pathological diagnosis in 17 patients, and right lung cancer was diagnosed by CT-scan and clinical examinations without pathological diagnosis in 14 patients. Clinical manifestations included edema of the face, neck and chest (31 cases), chest pain and difficulty in respiration (30 cases), dyspnea (23 cases), and varicosity over the chest wall (1 case). 29 patients were followed-up till death after treatment, with the follow-up time ranging from 2 to 20 months, and both clinical signs and radiological changes before and after the treatment were compared. Results Clinical symptoms and signs of these 31 patients were significantly improved after the treatment. The overall effective rate was 100% (CR 8 and PR 21) and the median remission time was 8.3 months. The longest survival time reached 19 months after the therapy. Conclusion Stereotactic radiotherapy seems to be a safe and effective treatment for patients with SVCS with a satisfactory response rate, short treatment period and long remission time.

Objective To evaluate the therapeutic efficacy of gamma knife in treatment of primary trigeminal neuralgia Methods Retrospectively analysis of 120 cases with primary trigeminal neuralgia treated by gamma knife in our department From Jan. 2003 to Mar. 2008 were performed. All cases were treated with the 4 mm collimator and targeted at the proximal nerve at the root entry zone located by MRI. The target dose varied from 80 -90 Gy. Results After a follow-up of 20. 0 ±4. 5 months, complete relief of pain occurred in 69 patients (57. 5%), 50% -90% relief in 34 (28. 3%), relief less than 50% in 12(10.0%) but no relief in 5(4.2 %).The efficient rate was 95. 8% . The common complications include numbness, absence of corneal reflex. 83 patients (69. 2%) experienced temporal facial numbness and 14 patients (11. 7%) reported continuous numbness after treatment of the gamma knife. Conclusions Gamma knife radiosurgery is a minimally invasive technique for the treatment of primary trigeminal neuralgia with few complications.

Objective To investigate the effects of Gegenqinlian Decoction on the IL-1β level in the patients with chronic periodontitis.Methods Seventy patients with chronic periodontitis were divided into the observation group and control group,35 cases in each group.The control group was given the periodontal basic treatment.On the basis of the control group,the observation group was given Gegenqinlian Decoction.The probing depth,attachment level and bacterial plaque index level before and after treatment were compared between the two groups.The levels of IL-1β and IL-6 in serum and gingival crevicular fluid were measured before and after treatment in the two groups.Results The total effective rate in the observation group was 94.29%,which was significantly higher than 71.43% in the control group,the difference was statistically significant (χ2=6.437,P<0.05).After treatment,the probing depth,attachment level and bacterial plaque index in the two groups were significantly decreased (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).The levels of IL-1β and IL-6 in serum and gingival crevicular fluid after treatment in the two groups were decreased significantly (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).Conclusion Gegenqinlian decoction can significantly reduce the IL-1β level in the patients with chronic periodontitis,reduces inflammation reaction and improves the therapeutic effect.

Objective To evaluate the value of ambulatory blood pressure monitoring in evaluating hypertension status and the efficacy of antihypertensive medication in hypertension patients.Methods We retrospectively collected data from 236 elderly hypertensive patients at our hospital from July 2016 to June 2017 and analyzed the blood pressure characteristics of patients under 24 h ambulatory blood pressure monitoring and the effects of different types of antihypertensive medication.Results Of 236 patients with high blood pressure,80.1％ had both higher systolic blood pressure and higher diastolic blood pressure;about 90.0％ had blood pressure load greater than 40.0％;blood pressure in 57.6％ of patients reached its peak both in the morning and in the afternoon;a majority (58.9％)showed a non dipper circadian pattern.After antihypertensive drug treatment,the blood pressure indicators significantly improved(P ＜0.05).Common antihypertensive drugs included calcium antagonists,angiotensin converting enzyme inhibitors (ACEI),angiotensin receptor blockers (ARB),diuretics,beta blockers,and combination drugs.Conclusions 24 h ambulatory blood pressure monitoring can provide comprehensive blood pressure data,help achieve accurate assessment of blood pressure status,and may be used in the evaluation of antihypertensive drug treatment.

Objective To investigate the relationship of the cytogenetic abnormalities detected by FISH in patients with MM and their clinical features. Methods FISH on bone marrow (BM) cells was performed in 57 enrolled MM patients. Relationships between cytogenetic abnormalities and clinical features were analyzed. Results By statistical analysis , both D13S319 deletion and RB1 deletion were associated with high level of serum LDH (P = 0.024; P = 0.018) and BM plasma cells index (P = 0.027; P = 0.013). 1q21 amplification was significantly associated with high level of LDH (P = 0.030 ) and the occurence of light chain type myeloma (P = 0.023). IgH rearrangement was associated with renal function damage (P = 0.009). There were correlations among D13S319 deletion, RB1 deletion, 1q21 amplification and IgH rearrangement (P<0.01). Conclusion The genetic abnormalities detected by FISH in patients with MM were correlated with various clinical poor prognostic indicators, which can evaluate the condition and prognosis of patients more efficiently.

Objective To observe the clinical characteristics of ophthalmic and cerebral artery occlusion after facial cosmetic injection.Methods A retrospective case study. Twenty patients (20 eyes) with ophthalmic and cerebral artery occlusion in Department of Ophtalmology, The Fourth Hospital of Xi'an from February 2014 to December 2016 were enrolled in this study. There were 2 males (2 eyes) and 18 females (18 eyes). They aged from 21 to 41 years, with the mean age of 29.8±1.4 years. The disease courses was ranged from 3.5 hours to 21 days, with the mean of 40 hours. Facial cosmetic injections of all patients were performed at out-of-hospital beauty institutions. The visual impairment was associated with eyelid pain 1 to 10 minutes after injection.There were 12 right eyes and 8 left eyes.The injection materials, 18 patients were hyaluronic acid and 2 patients were autologous fat, respectively. At the injection site, 13 patients were sacral, 4 patients were nasal, and 3 patients were frontal. The concentration and dose of the injected filler were not known. All patients underwent vision, slit lamp microscope, fundus color photography, visual field, FFA, OCT, and brain CT, magnetic resonance angiography (MRA) examination.Results The visual acuity was ranged from no light perception to 1.0. Among the 20 eyes, 3 eyes (15％) were obstructed by simple ophthalmic artery; 5 eyes (25％) were obstructed by ophthalmic artery combined with cerebral artery; 7 eyes (35％) were obstructed by simple retinal artery occlusion (RAO) alone, which including central RAO (CRAO, 4 eyes), hemi-lateral artery obstruction (1 eye) and branch RAO (2 eyes); 1 eye (5％) was CRAO with ciliary artery branch obstruction; 1 eye (5％) was branch artery occlusion with ischemic optic neuropathy; 2 eyes (10％) were CRAO with nasal dorsal artery occlusion; 1 eye (5％) was CRAO, posterior ciliary artery obstruction and right middle cerebral artery occlusion. Among 20 patients, 4 patients (20％) had eye movement disorder and eyelid skin bun; 2 patients (10％) had facial pain and nasal skin ischemic necrosis. MRA revealed 6 patients (30％) of new intracranial ischemic lesions. Among them, 5 patients of hyaluronic acid injection showed asymptomatic small blood vessel embolization; 1 patient of autologous fat injection showed ophthalmary artery occlusion, cerebral artery occlusion, ipsilateral eye blindness, eye movement disorder and contralateral limb hemiplegia.Conclusion Facial cosmetic injection can cause severe iatrogenic complications such as RAO, ciliary artery occlusion, ischemic optic neuropathy, ophthalmic artery occlusion, and cerebral artery occlusion.

In recent years, large numbers of non-coding RNAs (ncRNAs) have been identified in C. elegans but their functions are still not well studied. In C. elegans, CEP-1 is the sole homolog of the p53 family of genes. In order to obtain transcription profiles of ncRNAs regulated by CEP-1 under normal and UV stressed conditions, we applied the 'not-so-random' hexamers priming strategy to RNA sequencing in C. elegans, This NSR-seq strategy efficiently depleted rRNA transcripts from the samples and showed high technical replicability. We identified more than 1,000 ncRNAs whose apparent expression was repressed by CEP-1, while around 200 were activated. Around 40% of the CEP-1 activated ncRNAs promoters contain a putative CEP-1-binding site. CEP-1 regulated ncRNAs were frequently clustered and concentrated on the X chromosome. These results indicate that numerous ncRNAs are involved in CEP-1 transcriptional network and that these are especially enriched on the X chromosome in C. elegans.
