Objective:To explore the effectiveness and safety of simvastatin combined ezetimibe in patients with acute coronary syndrome (ACS).Methods:A total of 124 ACS patients complicated low density lipoprotein cholesterol (LDL-C)>100 mg/dl were selected from our hospital from May 2012 to May 2013. They were randomly and equal-ly divided into rosuvastatin group (received rosuvastatin 20mg/d)and combined treatment group (received simvasta-tin 40mg/d plus ezetimibe 10mg/d),both groups were treated for one month.Blood lipid levels and incidence rates of adverse reactions were observed in two groups.Results:Compared with before treatment,after one-month treat-ment there were significant reductions in levels of LDL-C,total cholesterol (TC)and triglyceride (TG)and signifi-cant rise in levels of high density lipoprotein cholesterol (HDL-C)in both groups (P <0.01 all),and there were no significant difference in all above blood lipid levels between two groups (P >0.05).Incidence rate of myalgia in combined treatment group was significantly lower than that of rosuvastatin group (4.8% vs.17.7%,P =0.023), but there were no significant difference in incidence rates of other adverse reactions between two groups (P >0.05 all).Conclusion:It′s effective and safe to use simvastatin combined ezetimibe in patients with acute coronary syn-drome,which is worthy extending.

OBJECTIVE:To observe the effectiveness and safety of different doses of rosuvastatin in the treatment of acute ce-rebral infarction. METHODS:Totally 120 patients with acute cerebral infarction were selected from Weifang Yidu Central Hospital during Jan. 2014-Dec. 2015,and then divided into observation group and control group according to admission order,with 60 cas-es in each group. Both groups received routine treatment as Shuxuening injection 10 mL,iv,1-2 times a day(or 20 mL added into 5% Glucose injection 250-500 mL,ivgtt,qd)+Aspirin enteric-coated tablets 0.1 g,po,qd. Control group and observation group were additionally given Rosuvastatin calcium tablets 10 mg and 20 mg,po,qd(after supper). Both groups were treated for 30 d. The levels of serum inflammatory factors(hs-CRP,TNF-α,IL-6),blood lipid indexes(TC,TG,LDL-C),neurological function and activity of daily life score were observed in 2 groups before and after treatment. The clinical efficacy and occurrence of ADR were recorded. RESULTS:Before treatment,there was no statistical significance in the levels of hs-CRP,TNF-α,IL-6,TC,TG and LDL-C,NIHSS scores and Barthel index (BI) scores between 2 groups (P>0.05). After treatment,the levels of hs-CRP, TNF-α,IL-6,TC,TG and LDL-C,NIHSS scores in 2 groups were decreased significantly,while BI scores were decreased signifi-cantly,observation group were significantly better than those of control group,with statistical significance (P<0.05). Total re-sponse rate of observation group (93.33%) was significantly higher than that of control group (86.67%),with statistical signifi-cance (P<0.05). The incidence of ADR in observation group (23.33%) was significantly higher than control group (6.67%), with statistical significance(P<0.05). CONCLUSIONS:Rosuvastatin can significantly reduce the inflammatory reaction and blood lipid level of patients with acute cerebral infarction,inhibit the formation of atherosclerotic plaque and improve prognosis. The large dose of rosuvastatin have better efficacy for acute cerebral infarction and can significantly improve the symptom of neurologi-cal deficits and daily living ability of patients.

Objective To study the expression and clinical significance of anty-apoptosis protein BAG-1 in non-small cell lung cancer(NSCLC),and its relationship with cell apoptosis and expression of Bcl-2 protein. Methods Immunohisto chemistry streptavidin-peroxidase conjugated (SP)method was used to examine the expression of BAG-1protein and Bcl-2 protein,and terminal deoxynucleotidyl transferase mediated UTP nick end labeling(TUNEL) method was used to examine the apoptosis index in 54 cases of NSCLC.The expression of BAG-1 protein in 20 cases of normal bronchus mucosa tissue also be detected as control.

Objective To evaluate the treatment and clinical outcome of pancreatic pseudocysts.Methods Clinical data of 53 pancreatic pseudocyst patients treated from Jan 2008 to Oct 2014 was retrospectively analyzed.Results 9 cases underwent CT-guided percutaneous catheter drainage,among them 3 cases underwent reoperation.8 cases underwent endoscopic ultrasonography-guided transmural drainage,including transgastric approach in 7,transduodenal approach in 1,Procedures in all these 8 cases were successful and pseudocyst disappeared completely without complication.Surgical procedures were performed in 36 cases,3 by external drainage,1 of the 3 underwent reoperation;11 cases underwent cystgastrostomy,with 2 suffering from postopertative gastrointestinal bleeding;3 cases underwent cystduodenostomy;19 cases underwent Roux-en-Y cystojejunostomy,with 1 suffering from postopertative gastrointestinal bleeding.Follow-up ranged from 4 months to 6 years,there was no cyst recurrence.Conclusion The treatment of pancreatic pseudocysts is diversified and should be individualized.Internal drainage is the mainstay of treatment,preferably through endoscopic ultrasonography-guided transmural drainage,leaving difficult cases to open cystojejunostomy.

Objective To study the clinical curative effect of Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen for treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). Methods A prospective study was conducted. Forty-six patients with DEACMP admitted into Yidu Central Hospital of Weifang Medical College from January 2012 to January 2014 were randomly divided into observation group (23 cases) and control group (23 cases). The basic treatments of two groups were identical. Based on the basic treatments including hyperbaric oxygen and citicoline sodium injection etc, the observation group was treated with our-self made Tongqiao Huoxue decoction which could be modified in accord to the individual differentiation of syndromes in traditional Chinese medicine (the composition of decoction included Paeoniae Radix Rubra 15 g, Chuanxiong Rhizoma 15 g, Persicae Semen 15 g, Carthami Flos 15 g, Zingiberis Rhizoma Recens 3 pieces, Jujubae Fructus 2 pieces, Moschus 0.5 g, Allium Fistulosum 1 segment). The decoction was administered orally or by nasogastric gavage, one dosage everyday for 1 month, and in the mean time, edaravone intravenously drip 30 mg was given to the observation group twice a day for 14 days. The control group was given hyperbaric oxygen and other conventional treatment for 30 days. The clinical therapeutic effect and adverse reaction were observed after treatment for 30 days. The changes of intelligent level were detected by Hasegawa dementia scale (HDS), and the changes of latency of P300 were measured by electromyologram/evoked potential instrument in two groups before and after treatment. Results The total effective rate in observation group was significantly higher than that in control group [91.3% (21/23) vs. 65.2% (15/23), P < 0.01]. Elevation of creatinine occurred in 1 case, moderate increase in alanine aminotransferase (ALT) appeared in 1 case, and both of them were reduced to normal after treatment in observation group; no adverse reaction occurred in control group. The HDS scores were significantly higher 30 days after treatment than those before treatment in the two groups [control group:13.4±2.8 vs. 6.8±2.3, observation group:20.8±3.4 vs. 6.6±2.5, both P<0.05]. The latency of P300 after treatment was significantly lower in two groups than that before treatment [control group (ms): 355.7±25.7 vs. 385.5±27.8, observation group (ms): 337.3±24.6 vs. 386.8±25.4, both P < 0.05], the change in observation group being more significant [the HDS score: 20.8±3.4 vs. 13.4±2.8, the latency of P300 (ms): 337.3±24.6 vs. 355.7±25.7, both P<0.05]. Conclusion Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen has favorable cognitive effect on patients with DEACMP, thus, it can be used extensively in clinic.

Objective To evaluate the clinical application value of reflectance confocal microscopy(RCM) in the diagnosis of several common diseases manifesting as papules in children, including lichen nitidus, verruca planae, lichen striatus, milium, molluscum contagiosum and lichen pilaris. Methods A total of 579 children clinically characterized by papules were recruited into this study. RCM was used to observe lesions and perilesional normal skin. The RCM features of 6 diseases manifesting as papules were analyzed and compared. Results Based on RCM images, 236 patients were diagnosed with lichen nitidus, 70 with verruca planae, 123 with lichen striatus, 40 with milium, 53 with molluscum contagiosum and 57 with lichen pilaris. All the 6 diseases had typical RCM features. Concretely speaking, RCM images of lichen nitidus lesions showed infiltration of dense inflammatory cells and melanophages in enlarged dermal papillae. In RCM images of verruca planae lesions, cells in the granular and spinous layers were arranged in concentric circles, giving a rose cluster?like appearance. RCM images of lichen striatus lesions revealed focal swelling of stratum spinosum, absent or local liquifaction degeneration of basal cells, and clustering of a moderate number of inflammatory cells in the superficial dermis. In RCM images of milium lesions, well?circumscribed round or oval structures containing highly but nonuniformly refractive materials could be seen in the dermis. RCM images of molluscum contagiosum lesions showed intact cystoid structures containing highly refractive molluscum bodies. Lowly to moderately refractive cutin ? like materials were observed along with the dilation of hair follicle infundibula in RCM images of lichen pilaris lesions. In RCM images, the 6 diseases were distinguished mainly based on structural features(patterns and refractivity)of skin lesions shown by continuous vertical scanning. Conclusion RCM is of great value to the diagnosis of diseases manifesting as papules in children.

Objective To investigate the prevalence of common thyroid diseases and urinary iodine levels in the population migrated from inland to coastal areas and to evaluate the epidemiological trend of thyroid disease in Heibei Cangzhou. Methods A retrospective analysis method was adopted. All the persons who were employees of enterprises and institutions,were divided into three groups:the migrated group,who migrated from Cangzhou City and the west counties of Cangzhou City to the Port of Huanghua where they had settled permanently because of the job; the inland group, who lived in Cangzhou City all the time and the seaport group, who lived in the Port of Huanghua for a long-term. Migrated groups were divided into stable occupants and intermittent occupants. During 2010 - 2016, a follow-up survey was conducted in the three groups at Examination Center of Cangzhou Central Hospital Physical. We compared the cumulative incidences of thyroid diseases including: chronic lymphocytic thyroiditis (CLT), nodular thyroid disease and Graves's disease (GD). In migrated group, 28 persons who occasionally lived in the Port of Huanghua were detected urinary iodine levels intermittently.We compared the two parts of urinary iodine level changes for three times by collecting a urine sample,including one part from people who lived in the Port of Huanghua continuously for more than a month,and another part of people who lived in Cangzhou or Hejian County for more than half a month then returned to Port of Huanghua. Results In 2010 - 2016, a total of 7 180 residents were surveyed, of which 2 012 were in the migrated group, 2 858 were in the inland group and 2 310 in the seaport group. The incidences of CLT and nodular thyroid disease were 2.29% (46/2 012)and 8.60% (173/2 012)in the migrated group,which were much higher than that of the inland group and the seaport group [1.05% (30/2 858), 5.42% (155/2 858); 1.47% (34/2 310), 6.88% (159/2 310), P < 0.01 or < 0.05]. At the same time,the incidences of GD was 0.45%(9/2 012) in the migrated group, which was higher than that of the inland group [0.10% (3/2 858), P < 0.05]. In migrated group, there were 1 503 residencies, including 482 stable occupants and 1 021 intermittent residents. The incidences of CLT and nodular thyroid disease in intermittent residents were 3.23% (33/1 021) and 9.89% (101/1 021), which were much higher than that of stable occupants [1.45% (7/482), 6.64% (32/482), P < 0.05]. The urinary iodine levels in the persons who lived in the Port of Huanghua occasionally (464.6 μg/L) were much higher than that of the persons who lived in Cangzhou for a long time(301.4 μg/L, U = 4.648, P < 0.01).There was a marked fluctuation of the median of urinary iodine determined 6 times which were 485.7,285.2,431.7,310.6,470.3 and 304.4 μg/L,respectively.Conclusions The incidence of many thyroid diseases of people migrated from inland to coastal areas has increased, which is not only higher than that of inland people,but also higher than that of coastal people.Large fluctuations in iodine intake due to migration flow and residential instability may be part of the reason for the high incidence of thyroid diseases. In the future, we should pay more attention to thyroid diseases of migratory population.

Objective:To explore the changes in serum metabolic profile in patients with oral squamous cell carcinoma (OSCC) and to identify the diagnostic biomarkers in order to provide new ideas for the early diagnosis of OSCC.Methods:In total, 76 OSCC patients who were diagnosed at the Department of Oral and Maxillofacial Surgery and 70 healthy individuals who at the Department of Medical Center of The First Affiliated Hospital of Zhengzhou University from August 2019 to January 2020 were recruited in The study. According to the random number table method, all subjects were divided into a test group ( n=96) and a verification group ( n=50). Subjects in the test group consisted of 51 OSCC patients and 45 healthy subjects and subjects in the verification group included 25 OSCC patients and 25 healthy individuals. Serum samples and clinical data of each of the subjects were collected. The serum samples were analyzed by ultra-high-performance liquid chromatography quadrupole-Orbitrap high resolution accurate mass spectrometry. Principal component analysis, orthogonal partial least square discrimination analysis and t-test were used to profile the differential metabolites in the test group. Pathway analysis of differential metabolites was performed. In addition, binary logistic regression analysis and receiver operating characteristic analysis were used in order to establish the potential diagnostic panel. Results:Twenty-one endogenous differential metabolites were identified showing significant association with OSCC. Results of pathway analysis suggested that OSCC associated with lipid metabolism and amino acid metabolism ( P<0.05). A novel diagnostic panel consisting of lysophosphatidylcholine (LysoPC) (16∶0/0∶0), LysoPC[18∶1(9z)/0∶0], taurine and D-glutamic acid was defined. The panel performed a high area under the receiver operating characteristic curve (0.998, 95% CI: 0.994-0.999, P<0.05). Conclusions:There were obvious lipid and amino acid metabolism disorders in OSCC patients. It was an effective method to establish a diagnostic model by metabolomics.
