MethodsThe data of 52 patients of PSDD evaluated on self rating depression scale(SDS) before and after treatment were analyzed statistically. ResultsThe curing rate of PSDD is about 78.85%.There was an apparent decrease in the level of SDS before and after treatment(P<0.001). ConclusionsThe treatment of integrated traditional Chinese and western medicine can produce a good effect on PSDD.

AIM: To study the causes of pyogenic granuloma after hydroxyapatite(HA) orbital implants.METHODS: HA orbital implants (250 cases) in our hospital (68 pegged implants) were reviewed.All patients were followed up from 18 months to 10 years. Implants were removed after medical therapy which was proved to be ineffective.RESULTS: Ten of 250 cases of HA orbital implants developed pyogenic granuloma. Pyogenic granuloma occurred in 1 unpegged implants patient and 9 patients after pegging and drilling of HA implantation over 4～7 years. The pyogenic granulomas were not controlled by medical therapy effectively. Implants were removed in 9 cases except 1 case denied removing and continued medical therapy.CONCLUSION: Pyogenic granuloma was serious complication that occurred after HA orbital implants. Partial vascularization, implant exposure, xenogenic sclera implant, pegging and drilling of HA implantation are risk factors that affect the development of pyogenic granuloma.Pyogenic granuloma hasn't relation with implanted peg material. Pyogenic granuloma denotes the potential implant infection, and all implants should be removed finally.

Objective To evaluate the effect of remffentanil postconditioning on myocardial ischemiareperfusion (I/R) injury in patients undergoing open heart surgery under CPB.Methods Thirty patients (ASA grade Ⅱ or Ⅲ, NYHA class Ⅰ or Ⅱ ) of both sexes aged 18-45 yr undergoing repair: of ventricular septal defect and/or atrial septal defect under CPB were randomly divided into 2 groups ( n = 15 each): control group (group C)and remifentanil postconditioning group (group R). Anesthesia was induced with midazolam, sufcntanil, propofol and rocuronium. The patients received 5 min infusion of remifentanil at 4 μg · kg- 1 · min - 1 8 min before aortic unclamping in group R, while the patients received equal volume of normal saline in group C. Blood samples were obtained from the right internal jugular vein for determination of plasma concentrations of cardiac troponin-I (cTnI)and MDA and activities of CK-MB and SOD before induction of anesthesia (baseline) and at4, 8, 24 and48 h after aortic unclamping. Results The plasma concentrations of cTnI and MDA and activity of CK-MB were significantly lower, while the plasma SOD activity was significantly higher at 4 and 8 h after aortic unclmping, and the plasma concentration of MDA was significantly lower at 24 h after aortic unclamping in group R than in group C ( P ＜ 0.05 ). Conclusion Remifentanil postconditioning can attenuate myocardial I/R injury in patients undergoing open heart surgery under CPB through inhibiting lipid peroxidation.

Objective To investigate the role of inducible nitric oxide synthase (iNOS) in reduction of myocardial ischemia-reperfusion (I/R) injury by sufentanil preconditioning in rats. Methods Thirty adult male SD rats, weighing 250-330 g, were randomly divided into 5 groups ( n =6 each): sham operation group (group S),I/R group, sufentanil preconditioning group (group SF), sufentanil preconditioning + a specific inhibitor of iNOS S-methyl thiourea (SMT) group (group SF+ SMT) and S-methyl thiourea group (group SMT). In I/R,SF,SF+SMT and SMT groups, myocardial I/R was produced by occlusion of left anterior descending coronary artery for 30 min followed by 120 min reperfusion. Group SF received 30 min infusion of sufentanil 120 μg/kg via caudal vein 24 h before ischemia. Group SF + SMT received infusion of sufentanil 120 μg/kg via caudal vein 24 h before ischemia and then SMT 10 mg/kg was injected 10 min before ischemia. In group SMT, SMT 10 mg/kg was injected 10min before ischemia. MAP and HR were recorded at 30 min before ischemia, at 30 min of ischemia and at the end of reperfusion. The rate-pressure product (RPP) was calculated. Arterial blood samples were obtained immediately at the end of reperfusion to determine the plasma concentration of NO. Then the animals were sacrificed and myo cardial tissues were obtained to determine the area at risk (AAR), infarct size (IS) and iNOS expression. IS/AAR was calculated. Results Compared with group S, MAP and RPP were significantly decreased, while IS/AAR was significantly increased at 120 min of reperfusion in the other four groups, and MAP and RPP were significantly decreased at 30 min of ischemia in I/R and SMT groups ( P ＜ 0.05). Compared with group I/R, no significant change was found in HR, MAP and RPP in SF, SF + SMT and SMT groups, and in IS/AAR and plasma NO concentrations in SF + SMT and SMT groups ( P ＞ 0.05), but IS/AAR was significantly decreased, and the plasma NO concentration and iNOS expression were significantly increased in group SF ( P ＜ 0. 05). Conclusion iNOS is involved in reduction of myocardial I/R injury by sufentanil preconditioning in rats.

Objective To investigation the pathological characteristics of esophageal squamous cell carcinoma to provide reference criteria for delineating the target area in radiotherapy.Methods Fifty-two patients from the Fourth Hospital of HeBei Medical University underwent resection whom all had been proved to have esophageal squamous cell carcinoma before operation.Chest CT was scanned and transmitted to the 3- dimensional conformal planning system for radiotherapy by VRX-16 scanner.The lesion of esophageal carcinoma was delineated in the 3-dimensional rebuild CT image and the lesion volume was computed by digital rebuild program.Every surgically resected specimen was made into pathologic giant section.The actual size of the specimen was obtained by calculating the size under the microscope with the shrinkage ratio.Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration were observed in the giant section with a microscope and the order of such pathological characteristics were analysed statistically.Results 1.The tumor length by different method of preparation of operated specimens differed obviously.The longest was shown by CT. 2.Multicentric carcinomatous lesion was found in 15(29%)cases out of 52 patients.Proximal to the tumor,the mean distance between the multicentric carcinomatous lesion and the main lesion plus the length of the multicentric carcinomatous lesion was 3.02?1.45cm.Distal to the tumor,it was 2.60?2.44 cm.Severe dysplasia was found in 28 patients.Proximally,the mean distance between the severe dysplasia and the main lesion plus the length of the severe dysplasia was 2.45?1.30 cm.Distal to the tumor,it was 3.24?2.19 cm.Direct intramural infiltration was found in 41 patients,of which the mean length being 2.80?1.52 cm proximally and 2.02?1.51 cm distally. 3.Tumor thrombus was found in 6 patients and lymphoduct infiltration in 36 patients.Direct intramural infiltration was found at higher incidence in specimens complicated with lymphoduct infiltration(86%)and those complicated with tumor thrombus(91%).There were no apparent factors affecting severe dysplasia.The proximal distance to direct intra- mural infiltration was much longer than distally.Conclusions Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration may be observed in esophageal squamous cell carcinoma.Multicentric carcinomatous lesion and direct intramural infiltration are obviously correlated with lymphoduct infiltration.To cover 95% of the microscopic extension,a margin of 5.0 cm is needed proximal to the base of gross tumor volume,and 7.5 cm distal to it.To cover 90% of the microscopic extension,a margin of 4.5 cm is needed proximally,and 5.0 cm distally.

OBJECTIVETo study the clinical characteristics of urticaria in children versus adults, and to provide reference for the etiological analysis, disease evaluation, and treatment of urticaria in children.

METHODSThe clinical data of 2 411 patients with urticaria who visited the Department of Dermatology at Xiangya Hospital of Central South University from January 2013 to May 2017 were collected to study their socio-demographic characteristics. The clinical characteristics of urticaria were compared between the 68 children and 672 adults of the 740 patients with complete follow-up data.

RESULTSAmong the 411 pediatric patients, 314 (76.4%) had acute urticaria; among the 2 000 adult patients, 896 (44.8%) had chronic spontaneous urticaria. The causes of acute urticaria in children included infection (41%, 16/39). The accompanying symptoms of acute urticaria in children mainly included abdominal pain and diarrhea (44%, 17/39), while those in adults mainly included chest distress and shortness of breath (32%, 11/34). Compared with the adult patients, the pediatric patients had significantly lower chronic urticaria activity scores before and after treatment (P<0.05), a significantly higher rate of response to second-generation antihistamines (82.1% vs 62.2%; P<0.05), and a significantly higher proportion of individuals with a personal and family history of urticaria (P<0.05).

CONCLUSIONSAcute urticaria is more commonly seen than chronic urticaria in children with urticaria, and the main accompanying symptoms are abdominal pain and diarrhea, which are different from adults with urticaria. Chronic urticaria has a better treatment outcome in children than in adults. The most frequently seen cause of acute urticaria is infection in children. Atopic children may be susceptible to urticaria.

Objective:To explore the application value of the method of judging the density of small shadows in the lung area by using CT and CT reference films for pneumoconiosis.Methods:The chest imaging data of 244 employees of a large copper company in Tongling City, Anhui Province who underwent occupational physical examination at Tongling Municipal Hospital in Anhui Province from January 2016 to December 2019 were retrospectively analyzed. Totally 244 cases underwent chest CT scan and chest DR radiography at the same time. The shape and size of the small shadows (the size of the circular and quasi-circular nodules in the lung area were represented by p, q, r, and the size of the irregular small shadows were represented by s, t, u), the overall density, the density of small shadows in each lung area, the large shadows, and the diagnosis stage were observed and compared. The small shadow density of each lung area was judged by the method of judging the small shadow density of CT lung area and the reference film, and other observation indicators were judged according to GBZ70-2015 Diagnosis of Occupational Pneumoconiosis. Results:There was a significant difference between CT and DR in judging s-shaped small shadows and no small shadows ( P<0.05), and there was no statistically significant difference in judging p, q, r, t, and u-shaped small shadows ( P>0.05). CT and DR had medium to high consistency in the judgment of the overall density of small shadows (Kappa=0.692, P=0.001), and the diagnostic coincidence rate was 82.38% (201/244). There was moderate to high agreement between CT and DR in the density of small shadows shown in the right upper, right lower, left upper, left middle, and left lower lung regions (Kappa ranged from 0.40 to 0.75, P<0.05), and the consistency in the right middle lung region was poor (Kappa=0.381, P=0.001). Eleven large shadows were detected in 8 cases by DR, 31 large shadows were detected in 23 cases by CT, and 20 (8.20%) large shadows were detected more frequently by CT than DR. The agreement between CT and DR for the diagnosis and staging of silicosis was excellent (Kappa=0.843, P=0.001), and the diagnostic coincidence rate was 91.80% (224/244). Conclusion:Applying the method of determining the density of small shadows in the lung area of pneumoconiosis and reference films, combined with GBZ70-2015 Diagnosis of Occupational Pneumoconiosis, can make a more accurate diagnosis of silicosis.

Objective To investigate the correlations of distribution and grading of deep medullary veins (DMVs) with clinical prognoses of patients with acute anterior circulation infarction by using susceptibility-weighted imaging (SWI).Methods Fifty patients with acute anterior circulation infarction,admitted to our hospital from August 2016 to December 2017,were enrolled in our study.SWI was performed to evaluate the DMVs.Univariate and multivariate Logistic regression models were used to determine the correlation between distribution of DMVs and clinical prognoses of patients.DMVs on the ipsilateral side of the lesions were further graded and analyzed;boxplot was used to describe its relation with modified Rankin scale (mRS) scores of the patients.Results DMVs were observed in 36 patients (72％),with 19 ipsilateral DMVs and 17 contralateral DMVs.The ipsilateral DMVs were independently associated with poor outcome (odds ratio=3.380,95％CI:1.006-11.393,P=0.049).The contralateral DMVs were not independent predictors for outcomes,but appeared commonly in patients with good outcome (44.8％).In patients with ipsilateral DMVs,grading 1,grading 2,and grading 3 were noted in 7,two and three patients,respectively;boxplot analysis showed that DMVs patients of grading 3 had higher mRS scores,with an average of 4.Conclusion The ipsilateral DMVs on SWI are independent predictive biomarkers for poor clinical outcome after stroke,and contralateral DMVs often indicate good prognosis.

This study was purposed to analyze and identify a novel HLA allele in Chinese population. A new HLA-B allele which is closely related to HLA-B*35:03:01 was initially detected by PCR-SSOP, then DNA sequencing was performed to identify the difference between the novel allele and HLA-B*35:03:01 allele. The result showed that the sequence of the new allele was different from all other known sequence. It differs from the closest matching HLA-B*35:03:01 by a single substitution at position 387 C→G in exon 3, no resulting in amino acid change. It is concluded that this allele is a novel one and has been officially named B*35:03:07 by the WHO Nomenclature Committee.
