OBJECTIVE:
To investigate the correlation between serum vitamin D level and clinical outcomes after repair of rotator cuff tears.
METHODS:
A total 122 patients who met the inclusion criteria and were followed up for 12 months from March 2018 to March 2020 were analyzed retrospectively, including 50 males and 72 females with an average age of(62.10±8.39) years old (ranged, 34 to 82 years old). All patients were divided into deficiency group(vitamin D<20 μg/L) and control group(vitamin D≥20 μg/L), including 62 cases in the deficiency group, with vitamin D (14.80±3.18) μg/L;60 cases in the control group, with vitamin D(25.17±5.64) μg/L. The two groups were compared in terms of age, gender, body mass index(BMI), tear size, degree of retraction, degree of fatty infiltration, injury factors, postoperative pain VAS score, postoperative shoulder joint function score, and re-tear rate. The age of all patients was divided into two categories:<60 years old and ≥60 years old;BMI was divided into <24 kg/m2 and ≥ 24 kg/m2;tear size was divided into ≤3 cm and >3 cm;retraction degree was divided into ≤2 cm and >2 cm;fat infiltration was divided into ≤2 grade and >2 grade;and the course of the disease was ≤3 months and >3 months. The correlation between Sugaya re-tear type and the variables listed above were analyzed and calculated.
RESULTS:
There were no major complications such as joint infection, anchor withdrawal and revision surgery in any of the 122 patients who were followed up on. There were no statistical differences in age, gender, injury factor, BMI, tear size, degree of retraction, degree of fatty infiltration, and duration of disease between the two groups (P>0.05). The Constant-Murley scores, UCLA scores, and ASES scores of the two groups all improved considerably after surgery(P<0.05);however, there was no statistical differences in the postoperative shoulder function scores between the two groups (P>0.05). There was significant difference in VAS between the two groups 1 month and 3 months after operation, with vitamin D deficiency group scoring higher, and there was no significant differences 6 and 12 months after operation. Tear size(>3 cm), degree of retraction(>2 cm), degree of fatty infiltration(>2 degree) were all shown to be the independent risk factors for retear after surgery by Logistic regression analysis(P<0.05). The comparison between the two groups of patients using a 2×5 row list showed that the Sugaya classification of rotator cuff re-tear(grade Ⅰto Ⅴ) between the vitamin D deficiency group and the control group was statistically different(t=14.228, P=0.007). It was discovered that the Sugaya classification after surgery was statistically different between the two groups.
CONCLUSION
Vitamin D deficiency is not correlated with clinical function scores and re-tear rate, however it is associated with the early postoperative pain (1 and 3 months) and the quality of rotator cuff healing (Sugaya classification) after surgery.

Objective:
To investigate efficacy of operation and non-operation treatment for hip fractures patients complicated with pulmonary embolism.
Methods:
A retrospective case control study was conducted to analyze the clinical data of 18 hip fracture patients complicated with pulmonary embolism admitted to Dongyang People's Hospital from May 2017 to January 2019. There were 11 males and seven females, aged 59 to 96 years[(80.0±9.3)years]. There were 10 patients with intertrochanteric fractures, one with femoral subtrochanteric fracture and seven with femoral neck fractures. After diagnosis of pulmonary embolism, the patients were given anticoagulant therapy with low molecular weight heparin for at least one week. The re-examination showed that pulmonary embolism absorption improved and D-dimer did not increase. Eleven patients chose surgical treatment (operation group) with intramedullary nail internal fixation or artificial hip replacement. Seven patients chose non-surgical treatment (non-operation group) with skin traction. The Harris score of hip function was compared between the two groups. Visual analogue scale (VAS) was used to evaluate hip joint pain. At the last follow-up, fracture healing, prognosis of pulmonary embolism and mortality within 3 months were recorded.
Results:
All the patients were followed up for 3-22 months [(11.2±6.0)months]. At last follow-up, the Harris score was (92.1±2.2)points in the operation group and (28.8±18.8)points in the non-operation group (

AIM To develop a sensitive, specific and reliable reversed-phase high performance liquid chromatographic method(RP-HPLC) to determine the total and unbound(free) concentrations in human plasma of amitriptyline and its major metabolite, nortriptyline. METHODS The assay involved a simple extraction procedure. The mobile phase consisted of acetonitrile and distilled water(30∶70, V/V), containing triethylamine(0.5%) and orthophosphoric acid(0.3%), pH 3.1. Separation was achieved on the C18 ODS column and the effluent was measured for UV absorption at 240 nm. RESULTS The calibration curves were linear in the range of 4~400 μg*L-1 for total concentration, and in the range of 4~64 μg*L-1 for free concentration for both amitriptyline and nortriptyline. The lowest limits of detection were 4 μg*L-1 for both compounds. The absolute recovery rates were 102.0%±3.77% for amitriptyline and 99.3%±7.13% for nortriptyline. The precision values(RSD) of intra-day and inter-day for both amitriptyline and for nortriptyline were determined to be <5%, and <8%, respectively. The method was applied to determine the total and free concentrations in plasma of the healthy volunteers after a single oral dose of 50 mg amitriptyline. CONCLUSION The assay was simple, repid, highly selective and sensitive. It is suitable for the routine analysis of total and free drug concentrations in plasma using readily available instruments with lower cost.

Objective To explore the safety and efficacy of the Wingspan stenting of basilar artery atherosclerosis stenosis though the analysis of single center massive clinical data. Methods Ninety one consecutive patients received Wingspan stenting because of basilar artery stenosis in our center from July 2007 to April 2013. The patients were classified into three groups:early term (n=30), middle term (n=30), and late term (n=31) according to the operation time in our center. The basic clinical data and the factors which may affect the ischemic events were retrospectively analysed, t test and Chi?Square test were used to analyze the factors related to the periprocedural ischemic complications. Results All of patients were stented successfully and the technical success rate was 100%(91/91). The mean stenosis was reduced from (82.2 ± 5.8)% to (15.9 ± 5.7)%; strokes or death happened in 13 cases within 30 days, including perforator stroke in 8 patients(8.8%, 8/91), thrombosis in 4 patients(4.4%, 4/91), subarachnoid hemo rrhage in 1 patient(1.1%, 1/91), 2 patients with disabling or fatal strokes. Lesions involving in the middle segment of basal artery (P=0.049), long?segment disease (P=0.002), severe stenosis (P=0.001) may be a risk factor affecting perioperative ischemic stroke, and the surgeons' surgical technique was not risk factors for ischemic complications (P=1.000). Seventy seven patients (84.6%, 77/91) had the clinical follow?up and the mean follow?up period was (31.3±15.1) months. Four patients suffered from posterior circulation strokes during the clinical follow?up , one of them (1.3%, 1/77) had disabling stroke, another 3 patients (3.9%, 3/77) suffered from TIA. The 2?year accumulate probability of stroke (any stroke or death within 30 days and stroke in the territory of the qualifying artery beyond 30 days)was 16%(95%CI, 8.2%to 23.8%). Forty six patients had the imaging follow?up and the mean follow?up period was(9.5±8.3)months, 6 patients(13.0%,6/46) had in?stent restenosis (ISR) and 2/6 patient had the symptomatic ISR. Conclusions The stroke or death rate of symptomatic basilar atherosclerosis Wingspan stenting within 30 days is high, but the disabling or fatal stroke rate is low. The middle segment of basilar artery involved, the long stenosis, the severe atherosclerosis may be the factors related to the periprocedural ischemic strokes. The incidence of disabling or fatal strokes was low following Wingspan stenting.

OBJECTIVE:
To study the clinical phenotype and gene mutation analysis of a hereditary abnormal fibrinogenemia family and explore its molecular pathogenesis.
METHODS:
The STA-R automatic hemagglutination analyzer to detect the proband and its family members (3 generations of 5 people) of prothrombin time(PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen activity (Fg: C), D-dimer (D-D), fibrinogen and fibrin degradation products (FDPs), plasminogen activity (PLG: A); The plasma levels of Fg: C and fibrinogen (Fg: Ag) were measured by Clauss method and immunoturbidimetry respectively. All exons and flanking sequences of FGA, FGB and FGG genes of fibrinogen were amplified by PCR, and the PCR products were purified and sequenced for gene analysis. The model was analyzed by Swiss software.
RESULTS:
The PT and APTT of the proband, her mother and sister were slightly prolonged, TT was significantly extend, Fg: C decreased significantly, Fg: Ag, PLG: A, D-D and FDPs are within the normal range; Her brother and daughter of the results are normal. Genetic analysis showed that g.7476 G>A heterozygous missense mutation in exon 8 of FGG gene resulted in mutations in arginine at position 275 of fibrinogen gamma D domain to histidine (Arg275His). Her mother and sister have the same Arg275His heterozygous mutation, brother and daughter for the normal wild type.
CONCLUSION
The heterozygous missense mutation of FGG gene Arg275His in patients with hereditary dysfibrinogenemia is associated with a decrease in plasma fibrinogen activity.
