Objective To survey the highly risk iodine deficiency regions of Shandong Province and to provide reference basis for further executing urgent iodine supply. Methods The annual document of cretinism in Licheng District in Jinan City and Shouguang City, the two iodine deficiency regions, were referred. Forty children aged 8-10 years of 2 targeted schools from 3 towns out of every targeted region underwent palpation, ultrasonography and As3+-Ce4+catalyzing speetrophotometry for ultra iodine examination. Twenty women aged 18-40 years from 2 villages sampled from every targeted town received ultra iodine examination and edible salt examination of iodine with direct titration. Results No new cretinism and suspected cretinism was found since 1995 in the regions. The goiter rates of children of the two regions detected with palpation and ultrasonography were 7.5% (18/241),6.2% (15/241) and 5.0% (13/259), 1.2% (3/259), respectively. Two hundred forty and 249 urine samples were respectively collected in school children, in which the median urinary iodine was 226.3,282.7 μg/L. One hundred twenty urine samples were respectively collected from the two group of women, resulting a median urinary iodine of 187.2,321.7 μg/L. Eight and 2 salt samples were free of iodine in 120 salt samples collected each region, respectively. The rate of qualified iodized salt was 100%. Conclusions It is not necessary to urgently implement iodine supply in Shouguang City and Licheng District. However, reinforcement of supervise on salt industry and eliminating the hazard from non-iodized and disqualified iodized salt remains in need.

ObjectiveTo introduction of perforator flaps,muscle flaps pedicled by descending branch of lateral circumflex femoral artery,method and their clinical application that multiple soft tissue defects of hand are repaire by muliplefoliated tissue flap only branch lateral circumflex femoral artery.MethodsFifteen patients with multiple soft tissue defects of hand were repaired muliplefoliated tissue flap only pedicled bydescending branch lateral circumflex femoral artery.At first,the anterolateral thigh perforator flap was designed and harvested according to the soft tissue defects of hand, then the descending branch lateral circumflex femoral artery was dissected at the same time the segmented perforator flap,fascia lata flap,rectus femoris muscle flap, vastus lateralis muscle flap, vastus intermedius muscle flap and distal spatium intermusculare flap were harvested in need according to distance among soft tissue defects.The muliplefoliated tissue flap was harvested only pedicled by descending branch lateral circumflex femoral artery, at last muscle flaps and fascia lata flaps were covered by skin graft, so the multiple soft tissue defects of hand were repaired in one time.ResultsNo vascular crisis happened. All skin grafts survived well, the contour of all repaired soft tissue defects was good and protective feeling was recovered by skin grafts of all flaps. All cases were got follow-up and the range was from 6 to 20 months(the average was 8.7 months).Wound of donor site healed well, muscle strength of quadriceps and motion of knee were normal. Three cases were excellent,nine cases were well and 3 cases were good, according to upper extremity function evaluation criteria of Chinese Medical Society for the Surgery of the Hand, the rate of good was 80 percent.ConclusionMultiple soft tissue defects of hand can be repaired by muliplefoliated flap only pedicled by descending branch of lateral circumflex femoral artery. Its advantages included reduction of operation time and treatment, good recovery of hand contour and function. It is a good method to repair multiple soft tissue defects of hand.

Objective To compare the efficacy of ultrasound-guided fine-needle aspiration(US-FNA)biopsy in diagnosing solid and complex thyroid nodules with different size. Methods One hundred and seventy-five thyroid FNA biopsies were prospectively performed on 168 patients ranging from 4 to 75 years of age. Sixty-three nodules were surgically excised and the others were clinically followed-up. The cytology diagnoses were categorized into four groups: benign, malignant, suspicious and unsatisfactory. Results There was no significant complication in the all 115 solid and 60 complex thyroid lesions and there were 36and 3 malignant nodules respectively in solid and complex thyroid nodules. The nondiagnostic rates of solid and complex nodules were 7％ and 8％. The accuracy of US-FNA in diagnosing complex thyroid nodules was comparatively equal to that of in solid thyroid nodules. In solid thyroid nodules, the sensitivity and accuracy in ≤1 cm group were similar to that of in ＞1 cm group. Conclusions US-FNA was an accurate and reliable method to diagnose thyroid solid and complex lesions.

Objective To investigate the safty and accuracy ot estimating the living donor's graft volume with IQQA liver imaging evaluation system.Methods Between June 2007 and July 2010,123living liver donors were enrolled to undergo 16-slice CT scanning,then graft volume was estimated by both IQQA and manu-traced multi-slice spiral computed tomography (MSCT) approach.The graft volume and time consuming between IQQA and manu-traced MSCT were compared. Pearson Correlation test was uesd to verify the correlation between the estimated graft volume estimated each method and actual graft weight detected in operation.Linear correlation analysis was done.Results The mean graft volume by IQQA and manu-traced MSCT was (856.76 ± 162.18) and (870.64 ±172.54) cm3 respectively preoperation.Paired t-test showed there was no statistically significant difference between IQQA and MSCT methods (P＞0.05).It took mean ( 16.9 ± 1.4) min to calculatethe graft volume by IQQA and (39.3 ± 2.1 ) min by manu-traced MSCT,respectively (P＜0.05).The real graft volume was (632.59 ± 13 1.73) cm3.Pearson correlation test showed the graft volume calculated by either IQQA or MSCT method had a significantly positive correlation with the real graft weight (MSCT r =0.921,IQQA r =0.896,P＜0.01 ).Graft weight could be expressed in the equation:Actual graft weight =- 150.303 + 1.025 × IQQA value or =- 94.397 + 0.955 × MSCT value.Conclusion IQQA system has same accuracy with MSCT method in predicting the graft volume but consuming less time.IQQA system promotes the recognition of clinician on liver three dimensional anatomic structure.

Objective To explore the clinical features of epilepsy after stroke. Methods One thousand and eighty-two patients with stroke, admitted to our hospital from June 2002 to December 2008,were chosen. The clinical data of 68 of these patients having epilepsy after stroke were collected; the clinical characteristics, seizure types and locations were summarized; the relations between epilepsy and both the stroke types and the locations of stroke lesions were analyzed. Results In patients with secondary epilepsy, the lesion of seizure mainly located in the temporal lobe with simple partial seizure as its main seizure type; patients with epilepsy secondary to cerebral hemorrhage had a higher prevalence as compared with those secondary to cerebral infarction and subarachnoid hemorrhage (P＜0.05). Patients with secondary epilepsy having their lesions in the lobes had a higher prevalence as compared with those having their lesions in other locations (P＜0.05) Conclusion Stroke patients having cerebral hemorrhage and lesions in the lobes are likely to have secondary epilepsy; the lesion mainly locates in the middle of the temporal lobe; simple partial seizure is common.

INTRODUCTIONPostoperative cerebrospinal fluid (CSF) leak is a serious complication following transsphenoidal surgery for which elevated body mass index (BMI) has been implicated as a risk factor, albeit only in two recent North American studies. Given the paucity of evidence, we sought to determine if this association holds true in an Asian population, where the BMI criteria for obesity differ from the international standard.

METHODSA retrospective study of 119 patients who underwent 123 transsphenoidal procedures for sellar lesions between May 2000 and May 2012 was conducted. Univariate and multivariate logistic regression analyses were performed to investigate the impact of elevated BMI and other risk factors on postoperative CSF leak.

RESULTS10 (8.1%) procedures in ten patients were complicated by postoperative CSF leak. The median BMI of patients with postoperative leak following transsphenoidal procedures was significantly higher than that of patients without postoperative CSF leak (27.0 kg/m vs. 24.6 kg/m; p = 0.018). Patients categorised as either moderate or high risk under the Asian BMI classification were more likely to suffer from a postoperative leak (p = 0.030). Repeat procedures were also found to be significantly associated with postoperative CSF leak (p = 0.041).

CONCLUSIONElevated BMI is predictive of postoperative CSF leak following transsphenoidal procedures, even in an Asian population, where the definition of obesity differs from international standards. Thus, BMI should be considered in the clinical decision-making process prior to such procedures.

Lysosomal dysfunction plays an important role in neurodegenerative diseases, including Parkinson’s disease (PD) and possibly Parkinson-plus syndromes such as progressive supranuclear palsy (PSP). This role is exemplified by the involvement of variants in the GBA1 gene, which results in a deficiency of the lysosomal enzyme glucocerebrosidase and is the most frequently identified genetic factor underlying PD worldwide. Pathogenic variants in the SMPD1 gene are a recessive cause of Niemann–Pick disease types A and B. Here, we provide the first report on an association between a loss-of-function variant in the SMPD1 gene present in a heterozygous state (p.Pro332Arg/p.P332R, which is known to result in reduced lysosomal acid sphingomyelinase activity), with PSP-Richardson syndrome in three unrelated patients of Chinese ancestry.

Purpose: Total neoadjuvant therapy (TNT) is becoming the standard of care for locally advanced rectal cancer. However, surgery is deferred for months after completion, which may lead to fibrosis and increased surgical difficulty. The aim of this study was to assess whether TNT (TNT-RAPIDO) is associated with increased difficulty of total mesorectal excision (TME) compared with long-course chemoradiotherapy (LCRT) and upfront surgery. Methods: Twelve laparoscopic videos of low anterior resection with TME for rectal cancer were prospectively collected from January 2020 to October 2021, with 4 videos in each arm. Seven colorectal surgeons assessed the videos independently, graded the difficulty of TME using a visual analog scale and attempted to identify which category the videos belonged to. Results: The median age was 67 years, and 10 patients were male. The median interval to surgery from radiotherapy was 13 weeks in the LCRT group and 24 weeks in the TNT-RAPIDO group. There was no significant difference in the visual analog scale for difficulty in TME between the 3 groups (LCRT, 3.2; TNT-RAPIDO, 4.6; upfront, 4.1; P=0.12). A subgroup analysis showed similar difficulty between groups (LCRT 3.2 vs. TNT-RAPIDO 4.6, P=0.05; TNT-RAPIDO 4.6 vs. upfront 4.1, P=0.54). During video assessments, surgeons correctly identified the prior treatment modality in 42% of the cases. TNT-RAPIDO videos had the highest recognition rate (71%), significantly outperforming both LCRT (29%) and upfront surgery (25%, P=0.01). Conclusion TNT does not appear to increase the surgical difficulty of TME.
