Concurrent thyroid carcinoma and parathyroid adenoma is rare, they can and do coexist. We present here a 63-year old man who had bilateral papillary thyroid carcinoma and a parathyroid adenoma in the right thyroid lobe. Thyroid cancer was confirmed surgically. After the operation, the patient was found hypercalcemie and hypophosphatemia along with an elevated parathyroid hormone (PTH), indicating primary hyperparathyroidism. Also, the parathyroid 99mTc-MIBI scan demonstrated parathyroid adenoma in the right lower pole of the thyroid. The abnormal parathyroid tissue was carried out, and then serum calcium and PTH levels decreased to normal ranges.

OBJECTIVE: To observe the clinical efficacy of Sodium Hyaluronate Eye Drops in combination with Recombinant Bovine Basic Fibroblast Growth Factor Eye Drops for dry eye after undergoing eximer laser in-situ keratomileusis(LASIK).METHODS: 62 cases(100 eyes) of patients with dry eye after undergoing LASIK were randomly divided into two groups: 32 cases(53 eyes) in the treatment group were treated with Sodium Hyaluronate Eye Drops in combination with Recombinant Bovine Basic Fibroblast Growth Factor Eye Drops,and 30 cases(47 eyes) in the control group with Sodium Hyaluronate Eye Drops alone(4 times/day,1～2 drops/time) for 2 months.The drug efficacy was observed for 1～3 months since 1 week after the initiation of medication.RESULTS: The total effective rate in the treatment group vs.the control group was 98.11% vs.89.36%(P

Objective To evaluate the clinical efficacy of percutaneous vertebroplasty (PVP) with flexible bone cement injector through unilateral puncture. Method Unilateral puncture line PVP treatment for thoracolumbar vertebral compression fracture was conducted in 78 patients, which was divided into observation group and control group according to the use of different equipment. The flexible bone cement injector was used in 36 cases of observation group, which injected the bone cement into three places at the vertebral body. The ordinary straight bone cement injector was applied in the 42 cases of the control group. The operation time, the time of radiation exposure, and the amount of bone cement injection were recorded, and the leakage of bone cement was observed. The visual analogue scale (VAS), relative vertebral height and Cobb angle were recorded at 1 week, 1 and 2 years follow-up. The time of operation, the time of radiation exposure, the amount of bone cement injection, the incidence of bone cement leakage, VAS, relative height of vertebral body and Cobb angle were compared between the two groups using independent samples t test orχ2 test. Result All patients in the two groups were successfully treated by surgery. There were no significant differences between the observation group and the control group in the operation time and the time of radiation exposure and the incidence of bone cement leakage (P>0.05). The injection amounts of bone cement in the observation group and the control group were (5.6 ± 0.7) and (3.2 ± 0.6) ml, with statistically significant difference (P<0.05). There were no significant differences in VAS score, relative vertebral height and Cobb angle between the two groups at 1 week after operation (P>0.05). At 1 year and 2 years after operation, the differences of the above indexes between the two groups were significantly different (P<0.05), with the observation group being superior to the control group. Conclusions Application of flexible bone cement injector for PVP operation is safe and feasible. Compared with the traditional straight bone cement injector, the use of flexible bone cement injector will not increase the operation time, radiation exposure time and the incidence of bone cement leakage but will improve the long-term effect.

Objective To study the efficacy of intravitreous injection (IVI) or sub-Tenaninfusion (STi) of triamcinolone acetonide (TA) for diabetic macular oedema. Design Retrospective cases series. Participants 37 cases (37 eyes) with diabetic macular oedema confirmed by fundus fluorescence angiography (FFA) and optical coherence tomography (OCT). Methods Patients were received 4mg TA by single intravitreous injection or 40mg TA by three times sub-Tenoninfusion at 0d, 2w, 4w. The best corrected visual acuity, fundus examination, intraocular pressure, fundus fluorescence angiography were further analyzed, and the retinal thickness of macular fovea were measured by OCT. Main Outcome Measures The visual acuity, thickness of retinal macular fovea, ocular pressure was measured. Results 32 cases (32 eyes) completed the 24 week followed-up. In group IVI, the visual acuity before and after injection was 0.10±0. 03, 0.24±0.06(F=15.459, P=0.000) respectively; and retinal thickness of macular fovea is(460.73±46.33)μm,(394.53±41.43)μm (F=25. 282, P=0.0000) respectively. But in group STi, the visual acuity before and after injection is 0.11±0.04, 0.18±0.07(F=6.989, P=0.000) accordingly; and retinal thickness of maculur fovea is (454.76±56.28)μm,(424.94±42.69)μm (F=5.145, P=0.000) respectively. There was obvious statistical significance between two methods at same time point(all P<0.05). The serious, irreversible complications had not been found in all patients during follow-up. Conclusion Triamcinolone acetonide by single intravitreous injection or repeatedly sub-Tenoninfasion are good ways to relieve diabetic macular oederna, IVA-TA is more effective, and STi-TA safer.

Objective To investigate the mechanism of the pathogenesis of diabetic nephropathy (DN) by detecting the expressions of transforming growth factor (TGF)-β, Smad proteins andα-smooth muscle actin (α-SMA) in kidney biopsy of patients with diabetic nephropathy (DN). Methods Twenty-eight patients with DN who underwent renal biopsy were col-lected as DN group. Ten subjects without DN who underwent nephrectomy were taken as control group. The expressions of TGF-β1, TGF-βRⅠ,TGF-βRⅡ,Smad2/3 andα-SMA in renal tissues were detected by immunohistochemistry stain. Results (1)TGF-β1,TGF-β RⅠ,TGF-β RⅡ,and Smad2/3 were expressed in the glomeruli and tubules of both DN group and control group, while the expressions of TGF-βand Smad proteins were significantly higher in DN group than those in control group. At the early stage of DN, TGF-βand Smad proteins were significantly expressed even though there was no remarkable lesions observed by light microscopy. There was no correlation between increased expression and the progres-sion of DN. These proteins were not expressed after glomerulus and renal tubule fibrosis. (2) In control group,α-SMA was identified only in the vascular walls, glomerulus and renal tubules, while it was expressed in almost all parts of kidney in DN group. Conclusion TGF-β and Smad signals involved in the pathogenesis of DN, which may have similar pathogenesis with immune complex glomerulonephritis.

Objective To investigate the screening significance of transcranial Doppler (TCD) for patients with patent foramen ovale ( PFO) induced cerebral embolism and to improve the treatment aiming at the causes.Methods Thirty-six patients of less than 60 years old with unknown-cause cerebral embolism and transient ischemic attack were enrolled.Besides conventional examination,the 24 h Holter,transthoracic echocariiography,carotid artery Doppler ultrasonography (CAU),routine TCD,TCD foaming test,transesophageal echocardiography (TEE),CT angiography (CTA) of head and neck,ultrasonography of vein in bilateral lower limbs were examined in all patients.Results All the patients showed no atrial fibrillation.No structural heart disease and intracardiac occupying lesion were shown in transthoracic echocardiography.No carotid stenosis was shown in carotid artery Doppler ultrasonography.Routine TCD showed no intracranial artery stenosis.No thrombus was found in ultrasonography of deep veins in bilateral lower limbs.CTA of head and neck showed everything was normal.Fourteen patients were observed with right-to-left shunt in heart by TCD foaming test,including 10 cases with microbubble signals(MBS) in 10 s,and 4 cases with MBS after Valsalva maneuver.Among 14 patients,12 patients were proved PFO by TEE.Conclusions PFO is one of the causes of cardiogenic cerebral embolism.TCD is accurate and reliable for the screening of PFO.

Objective:To explore the application of ArcCheck system in the validation of Helical and Direct tomotherapy plans for esophageal cancer and summarize relevant experience.Methods:The Helical and Direct tomotherapy verification plans were established for 32 patients with esophageal cancer at different positions according to the doctor′s instructions, which were verified by the ArcCHECK system to compare the passing rate of the results.The correlation between the volume of the target area and the passing rate of the planned verification was analyzed. The therapeutic verification plan with a small target volume was made. The target area was placed at the center of ArcCHECK phantom and the area of detectors to statistically compare the verification passing rates.Results:Helical plan showed a significantly higher passing rate than the Direct plan ( P<0.01). The correlation coefficients between the target volume and the passing rate of the Helical and Direct plans were -0.364 and -0.042, and the P values were 0.041 and 0.819, respectively. For the Helical plan, when the 3%/2mm criterion was adopted, there was significant difference between placing the high-dose area at the center of the phantom and the area of detectors ( P=0.005), and the passing rate of the latter was higher. There was no significant difference in the other cases (all P>0.05). Conclusions:The passing rate of the Helical plan is generally higher than that of the Direct plan, which may be related to the angular response of the ArcCHECK detector and the fact that more reference points are not included for calculation due to low-dose radiation. In addition, it may also be related to the higher requirements of Direct plan for tomotherapy dose control system. In the Helical verification plan, when the 3%/3mm criterion is adopted, the larger the target volume, the higher the possibility of lower passing rate, whereas the correlation coefficient between them is relatively low. The high-dose area can be verified by the plans at the center of the phantom or the detection point. With the comprehensive consideration, we suggest putting it at the center of the phantom.

Objective: To analyze the influencing factors and mechanism for unprotected sexual behavior of men who have sex with men (MSM) in China. Methods: MSM who are more than 16 years old and have had homosexual sexual behaviors in recent years were recruited from five cities (Tianjin, Harbin, Nanjing, Chongqing and Xi'an) with active MSM population during 2013-2014 through network, site recruitment and peer recommendation using convenient sampling method. 3 519 subjects were included in this study. The sexual behavior related information of MSM in five cities was investigated using questionnaires. The confirmatory factor analysis was used to construct the measurement model by using the robust estimation method based on the weighted least square method to estimate parameters, and the final model was determined through evaluation and modification. Results: A total of 3 519 subjects were (29.9±8.76) years old, with a clear sexual orientation of 3 223 (91.6%), and 2 287 (65.0%) were aware of free HIV/AIDS treatment policies. The proportion of using condom last time was 77.2% (n=2 718), and the proportion of using condom every time was 36.9% (n=1 299) and 43.2% (n=1 521) respectively for the past six months with fixed and temporary partners. Structural equation model provided a good fit, the root mean square error of approximation, comparative fit index and non-normed fit index was 0.07, 0.97, 0.95, respectively. Knowing AIDS knowledge, educational level and sexual orientation had direct effects on unprotected sexual behavior, and the path coefficients were 0.179,-0.049 and -0.159, respectively. While the role of interventions was indirect, the path coefficient was 0.147. Conclusion Lower education and unclear sexual orientation are disadvantages for reducing unprotected sexual behavior. Interventions mainly affect the unprotected sexual behavior by improving the level of HIV/AIDS knowledge. Increasing the comprehensive knowledge of MSM through intervention should be highly valued.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.
