Objective To summarize the ruptured types and surgical treatment experience for rupture of aortic sinus aneurysm. Methods Nineteen cases with aneurysm of aortic sinus were retrospectively analyzed. There were 10 cases with ventricular septal defect,6 cases with aortic valvular incompetence,6cases with other diseases,2 cases complicated by infective endocarditis. All cases underwent operational treatment. Results There were 15 cases of right aneurysm of aortic sinus,including 12 cases among them ruptured into right ventricle,3 cases rupture was penetrated into right atrium.There were 3 cases of null aneurysm of aortic sinus,including 1 case among them ruptured into right ventricle,2 cases ruptured into right atrium. There was 1 case of left aneurysm of aortic sinus, which ruptured into left ventricle. No operative death occurred in all, 1 case with aortic regurgitation light to moderate,and all cases were recovered.Conclusions The right aneurysm of aortic sinus is the most common types,and always rupture into right ventricle. It is important that aneurysm of aortic sinus should be operated as early as possible in order to avoid losing the chance of operation, particular in the patients complicated by infective endocarditis.

Objective To investigate sleep quality and it’s influencing factors of hypertensives among rural area in Hubei Province. Methods The method of stratified sampling by selecting 569 hypertensives in Xuanen county of Hubei was applied to perform the questionnaire survey, including the sociodemographic data, daily life habits and physical health data, as well as pittsburgh sleep quality index(PSQI) and compliance of hypertensive patients scale(CHPS). Results The average score of PSQI in 569 hypertensives was 7.25±3.61, of which 251(44.11%) hypertensives were poor sleep quality. The influencing factors of sleep quality for hypertensives are gender (P=0.006, OR=1.626), the number of other diseases(P=0.001, OR=1.520), regular exercise (P=0.033, OR=0.660) and the compliance of hypertensives (P=0.024, OR=1.707). Conclusions The sleep quality of rural hypertensives in Xuanen county, Hubei Province is poor, which is affected by different factors. Therefore effective measures should be taken to improve the sleep quality of hypertensives.

The recombinaut porcine insulin precursor(PIP)produced by Pichia pastoris in shake-flask and 501.fermenter was investigated respectively.The results indicated that 60h induction time length and 2.0%～2.5% methanol addition every day was optimum in shake- flask.The process in 50L fermenter was consisted of batch,feed-batch and induction phases.The relationship between dry cell weight(y) and culture time (t) in growth phase(batch and feed-batch phase)could be described by model y=0.6525e~(0.1907t).Glycerol and ammonia were almost used for cell growth and maintain,and no by-product was observed in batch and fed-batch phase Only 80% ammonia and 70% methanol were used by cell in induction phase.By comparison the results of shake-flask and 50L fermenter,it was concluded that the limit- ing factor in the fermentation of shake-flask and 50L fermenter was dissolved oxygen(DO)and.carbon source,respectively.When scaling the result of shake-flask to 501.fermenter,the control strategy was adapted for 50L fermenter by increasing the feed rate of methanol and the maximum PIP concentration reached 1.72 g/L.

Objective To evaluate the role of 131I SPECT/CT in post-surgical re-staging and recurrence risk stratification in patients with DTC and its impact on subsequent treatment strategy.Methods 131I-WBS and 131I SPECT/CT were performed at the same time 5 to 7 d after 131I treatment in 118 patients (33 males,85 females,average age 45 years) with DTC.Difference in the localization and qualitative diagnosis of 131I uptake lesions between 131I-WBS and 131I SPECT/CT were compared.Value of 131I SPECT/CT in the diagnosis of TNM staging,risk stratification and impact on the treatment strategy was evaluated.Paired χ2 test was used for data analysis.Results A total of 509 foci with 131I uptake were detected.131I-WBS found 449 foci with 131I uptake,354 of which (78.84％) were correctly diagnosed.131I SPECT/CT found 509 foci with 131I uptake,and 504(99.02％) were correctly diagnosed.The difference was statistically significant (χ2=21.51,P<0.01).131I-WBS changed the clinical staging in 13 cases with diagnostic accuracy of 5/13.131I SPECT/CT changed the clinical staging in 19 cases and with diagnostic accuracy of 19/19 (χ2=74.41,P<0.01).131I-WBS changed the risk stratification of 13 patients after operation and the accuracy was 5/13,the corresponding data were 22 and 100％(22/22) for 131I SPECT/CT (χ2=74.41,P<0.01).The treatment strategy was changed in 50 patients with 131I SPECT/CT.Conclusions Compared with 131I-WBS,131I SPECT/CT could provide more accurate positioning and qualitative information for 131I treatment and is more accurate in re-staging and risk stratification.

Chemotherapy-induced neuropathy is a serious clinical problem for patients receiving cancer treatment. The aim of this study was to investigate the potential efficacy of pregabalin in chemotherapy-induced neuropathy in rats. A total of 35 male Sprague-Dawley rats were randomly divided into 5 groups: group 1, naive control; group 2, treated with pregabalin (30 mg/kg p.o., for 8 days); group 3, docetaxel was given by single intravenous infusion at 10 mg/kg; groups 4 and 5, pregabalin at 10 mg/kg and 30 mg/kg respectively was orally administered for 8 days after the docetaxel treatment. On day 8, behavioral test was performed, and substance P and CGRP release in dorsal root ganglion (DRG) and sciatic nerve were analyzed by electron microscope. Our results showed that docetaxel induced mechanical allodynia, mechanical hyperalgesia, heat hypoalgesia, cold allodynia, and sciatic nerve impairment and substance P and CGRP release in DRG. However, oral administration of pregabalin (10 mg/kg and 30 mg/kg) for 8 consecutive days significantly attenuated docetaxel-induced neuropathy by ameliorating heat hypoalgesia, cold allodynia, impairment of sciatic nerve and reducing the release of substance P and CGRP. The findings in the present study reveal that pregabalin may be a potential treatment agent against chemotherapy-induced neuropathy.

Objective To study the correlations of VDR FokⅠgene polymorphism with type 2 diabetes in postmenopausal women of Han nationality in south Sichuan. Methods 160 patients with type 2 diabetes (T2DM) and 190 healthy cases were enrolled in the study. The VDR FokⅠgene polymorphisms were detected using RFLP-PCR and DNA sequencing. Results The FF, Ff and ff genotype frequencies were 32.5%, 47.5%and 20% in the T2DM group and 15.8%, 53.7%, 30.5% in the control group, respectively (P < 0.05). The allele frequencies were 56.3%, 43.8% in the T2DM group and 42.6%, 57.4% in the control group, respectively (P < 0.05). The risk of T2DM in the FF genotype people was 2.568 times higher than Ff/ff genotype (adjusted OR = 2.568, 95%CI = 1.246 ~ 5.292, P < 0.05). The levels of 2 h PG and HbA1C in the FF genotype people were significantly higher than those of the Ff/ff genotype people (P<0.05). Conclusions There was an association between the VDR FokⅠgene polymorphism and type 2 diabetes incidence in the postmenopausal women in south Sichuan area.

Objective To verify and monitor the performance of accuracy, precision and comparability of 26 clinical biochemical analytes (29 methods) in the six centers involved in multi-centers reference intervals research, and to ensure the reliability of theirmeasurement results.Methods During the period of the systems evaluating, two levels of commercial quality control materials and fresh frozen human serum reference materials were applied to verify the performance of inter-laboratory precision and accuracy of analysis systems. During the period of samples testing, the commercial quality control materials were measured whenever samples were analysed, the fresh frozen serum reference materials were measured once a month.The coefficient of variations (CVs), bias and total errors were calculated to assess the precision, accuracy and comparability.Results Verification of precision and accuracy: ( 1 ) the ranges of CVs of 29 methods in the six laboratory laboratories were 0.4%-6.0%, the CVs of all 29 methods met the criterion . (2) The overall average bias of the analysis systems of 21 analytes (24 methods) ranged from -5.15%( ALT) to 4.46% ( Ur ) .Among 24 methods the overall average bias of TP, Glu-GOD, Ur, Cl, Ca exceeded the acceptable range.The quality assessment during the period of samples testing:(1) The overall average bias ranged from -1.95%(Ca) to 2.92%(Ur), median 1.26%, they all met the requirements of relevant standards.( 2 ) When commercial control materials were tested, the requirements of CVs were fulfilled for most methods in the six laboratories,and the CVs of TP, Alb, Cl, Ca exceeded the acceptable range.The overall average TE of all methods met the quality specification for the C-N controls material.For the C-P control material, only the overall average TE of TP (5.05%) exceeded thearceptable range while the other methods met the requirement in criterion.Conclusions The performance of precision and accuracy of the analysis systems used in the six laboratories passed the verification.During the period of sample testing, the performance of precision and accuracy of the most methods in the 6 laboratories met the requirements of quality specifications, and the overall performance was good.Because of the limitation of current technology the performance of some methods didn't fulfill the requirement of specifications, and need to be improved.

Objective: To evaluate the effects of continued acceptance and commitment therapy intervention on post-traumatic growth of postoperative patients with breast cancer. Methods: According to the hospitalization time, 120 patients with breast cancer were divided into observation group (62 cases) and control group (58 cases). From January to December 2017, 58 patients were used as control group. Regular health education and discharge follow-up were performed. Intervention with the commitment therapy 3 times; 62 patients from January to December 2018 were selected as the observation group. On the basis of the control group, the patient continued to receive and commit the intervention for 3 to 4 times from February to March after discharge. The post-traumatic growth status of patients before, at the time of discharge (after the intervention), at the hospital for 2 months, at the hospital for 3 months, and at the hospital for 6 months was assessed using the Simplified Chinese version of the Post-Treatment Growth Rating Scale (PTGI). Results: There was no significant difference in the post-traumatic growth scores between the two groups (P>0.05). The post-traumatic growth scores of the two groups were 67.02±14.17, 66.93±14.24, which were better than 51.72±11.65, 51.86±11.67 before the intervention (t= 7.634, 7.725, P<0.05). At 3 months and 6 months after discharge, the post-traumatic growth scores of the observation group were (67.12±14.07) and (68.21±14.48), which were significantly better than the control group (54.17±11.64). 54.02±11.12), the difference was statistically significant (t= 7.957, 7.674, P<0.01). Conclusion Acceptance and commitment therapy intervention during hospitalization can effectively improve post-traumatic growth of postoperative patients with breast cancer. Continued admission and commitment therapy intervention after discharge can provide patients with out-of-hospital continuous care programs to improve post-traumatic growth of postoperative patients with breast cancer. It has a better long-term effect than the control group.

AIM: To study the clinical efficacy, complications and visual related quality of life(VRQoL)of Ozurdex in the treatment of macular edema secondary to retinal vein occlusion(RVO-ME).

METHODS: Totally 30 patients with ME, which had developed secondary to either CRVO(13 eyes)or BRVO(17 eyes), were monitored for 6mo after treatment with Ozurdex in the Department of Ophthalmology of our Hospital. We measured the best corrected visual acuity(BCVA), intraocular pressure(IOP), central macular thickness(CMT)at different time after treatment(1wk, 1mo, 2mo, 3mo, 4mo, 5mo, and 6mo after treatment), and we also measured the Chinese version vision related quality of life questionnaire-25(CVRQoL-25)at 3mo after treatment and compared them separately with the ones measured before treatment to evaluate the efficacy, adverse reactions and the visual related quality of life.

RESULTS: Generalized estimation equation results showed that BCVA, CMT and IOP all had differences at different time points(P<0.001). A BCVA increase was achieved and CMT decreased in all patients at any time point after the onset of treatment(P<0.001). The changes of BCVA and CMT were the largest in the 2mo compared to the baseline(P<0.001). The score of CVRQol-25 at 3mo after treatment was significantly higher than that before treatment and then the central retinal thickness decreased and a BCVA increased compared to the baseline level(P<0.01). The score of CVRQoL-25 at 3mo was negatively correlated both with the LogMAR BCVA evaluated before treatment and at 3mo after treatment(rs= -0.717, -0.746, all P<0.001); Meanwhile, the score of CVRQoL-25 was also negatively correlated with CMT at 3mo after treatment(rs= -0.862, P=0.001). In 19 eyes(63%)of the patients with RVO-ME,a relapse was observed after a follow-up time of 1-3mo and the average recurrence time was(2.8±0.5)mo. In follow-up of 6mo, about(2.3±0.4)intravitreal Ozurdex injections per eye was observed. The increase in IOP was observed at 1wk, 1, 2, 3mo after pretherapy(P<0.05). The mean IOP values reached a peak at 2mo after injection, which rose(7.85±0.32)mmHg above the baseline level(P<0.05)and decreased to normal at 4mo after treatment. 10% of patients had an elevation in IOP above 25mmHg, which could be medically controlled and 4 eyes(13%)of patients had cataract formation, two of which needed to surgery.

CONCLUSION: Ozurdex proved to be efficacious with increase in visual acuity and reduction of central retinal thickness and improve the visual function-related quality of life of RVO-ME patients. After single injection of Ozurdex, visual acuity benefited for 2-3mo. 63% of the patients relapsed at about 3mo after treatment. Adverse reactions associated to the use of Ozurdex include the formation of cataracts and an increase in IOP.
