Objective To explore the rationality of correcting urinary iodine (UI) concentration by using urine specific gravity (U-SG).Methods Weighing method and refractometer method were used respectively to measure specific gravity of 10-30 g/L mass concentration of different inorganic salts (sodium chloride,sodium sulfate,ammonium biphosphate) and organic matters(urea,glucose,glycine) aqueous solution,and urine plus 10-30 g/L sodium chloride or urea.UI concentrations in urine samples of 27 pregnant women respectively were expressed by direct method,weighing method U-SG correction and refractometer method U-SG correction.One random urine sample was collected for six batches in different seasons from children aged 8-10 and pregnant women for determination of U-SG and UI concentration.UI concentration was determined by arsenic cerium catalytic spectrophotometry (WS/T 107-2006).Results ①Measured by weighing method,specific gravity of inorganic salt (sodium chloride,sodium sulfate,ammonium biphosphate) aqueous solution was significantly greater than that of organic matters (urea,glucose,glycine) aqueous solution which had the same mass concentration.The specific gravity of 10 g/L sodium chloride aqueous solution was 1.008,and that of 30 g/L urea solution was 1.006.②Measured by weighing method,10 g/L sodium chloride was added to 3 urine samples separately.Accordingly the increases of USG were 0.006,0.008 and 0.007,respectively.Otherwise,the increases of U-SG were 0.003,0.002 and 0.004,respectively,when adding 10 g/L urea.~he median results of UI concentrations in urine samples from 27 pregnant women were 106.4,165.2 and 211.8 μg/L,respectively,expressing obtained by direct method,weighing method USG correction and refractometer method U-SG correction.④The determination results of six batches urine collected from children aged 8-10 in different seasons,the median results of U-SG measured by refractometer method were 1.019 0-1.021 2,the median UI concentration results obtained by direct method and refractometer method U-SG correction were 134.5-181.7 μg/L and 157.7-190.4 μg/L.The determination results of six batches urine samples of pregnant women in different seasons,the median results of U-SG measured by refractometer method were 1.013 4 -1.017 1,the median UI concentration results obtained by direct method and refractometer method U-SG correction were 96.2-138.9 μg/L and 135.2-181.6 μg/L.Conclusions The change of sodium chloride concentration in urine is the most important reason for the change of U-SG.In China,the main source of UI is the intake of edible iodized salt.Iodized salt intakes directly affect the U-SG and UI concentration.If the U-SG is used to correct the UI concentration,there will be a phenomena that the lower intake of iodized salt the lower U-SG.So the UI concentration was falsely increased significantly after correction.Conversely higher intakes of iodized salt caused higher U-SG.The UI concentration was falsely reduced significantly after correction.Therefore,U-SG cannot be used to correct the UI concentration.

Objective To observe clinical efficacy of Qilin Pills combined with Three-Spot Caressing in the treatment of acquired non-consolidated kidney qi premature ejaculation (PE). Methods Totally 129 acquired non-consolidated kidney qi PE patients were randomly divided into TCM group, Fangzhognshu group and combination group. TCM group was given Qilin Pills, 6 g each time, three times a day, orally. Fangzhognshu group was guided to conduct Three-spot Caressing during sexual intercourse, no less than twice a week. Combination group was given Qilin Pills and Three-spot Caressing with the same method as Fangzhognshu group. The treatment course for each group lasted for 8 weeks. Before and after treatment of 4 weeks, 8 weeks and 4 weeks after with drawal, the intravaginal ejaculatory latency time (IELT), Chinese Index of Sexual Function for Premature Ejaculation-5 (PECI-5) scores and TCM syndrome scores (TCMS) were compared. Results Compared with before treatment, IELT increased in three groups at different time points after treatment (P<0.05). In the combination group, IELT was superior to the other two groups (except for TCM group after 4-week treatment), with statistical significance (P<0.05). Compared with before treatment, PECI-5 scores improved in three groups (except for Q6 and Q7 in Fangzhongshu group after 4-week treatment) at different time point after treatment (P<0.05). The improvement of Q5, Q6 and Q7 scores in PECI-5 of combination group was significantly better than that in the other two groups at 8-week treatment and 4-week after treatment (P<0.05). Compared with before treatment, TCMS in TCM group and combination group were improved significantly (P<0.05), PE and loss of libido score improved significantly in Fangzhongshu group (P<0.05);mental malaise and move spontaneous perspiration were significantly improved at 8-week treatment and 4 weeks after treatment (P<0.05). The improvement in TCMS was significantly better in combination group than that in the other two groups at 8-week treatment and 4 weeks after treatment (P<0.05). Conclusion Qilin Pills combined with Three-Spot Caressing has definite and long-term efficay for the treatment of acquired non-consolidated kidney qi PE.

Though great progress on spinal sagittal alignment has been seen recently, which focuses on the lumbar spine-pelvic region and the whole spine, while there is a few research mainly concentrated on the cervical spine. In recent years, a growing number of researchers have been exploring the changes in the compensation of cervical sagittal alignment and their effect on surgery, and the preliminary results of these researches are satisfactory. The present review focuses on the measurement of sagittal plane parameters of cervical spine, changes of sagittal alignment in cervical spine disorders, and its effect on cervical surgery.

Lumbosacral transitional vertebrae (LSTV) is a common phenomena of developmental anomaly, which is characterized by anatomic variation and biomechanical changes. LSTV is often accompanied with low back pain, lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis and other spinal diseases. The diagnosis of LSTV has a great significance for proper treatment process. Early imageological studies have limitations on distinguishing different types of LSTV from the aspect of morphological changes. This review focuses on recent studies of LSTV anatomy and variation, its influence in local biomechanics and spinal alignment, and its relationship with spinal diseases.

Postoperative delirium is a common complication after spinal surgery, and it is a complex issue involving multiple factors. However, there is currently insufficient understanding of postoperative delirium in patients undergoing spinal surgery, and there is still a lack of clear regulation in prevention and treatment. Although the literature and research on postoperative delirium have been comprehensive, there are still few studies on postoperative delirium in patients undergoing spinal surgery. This article mainly reviews the incidence, social and economic problems, risk factors, prevention and treatment of postoperative delirium in patients undergoing spinal surgery.

Objective To investigate clinical effects and prognostic factors of transabdominal laparoscopic-assisted and open radical resection for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cohort and case-control studies were conducted.The clinicopathologieal data of 84 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to the First Affiliated Hospital of Xiamen University from January 2014 to January 2017 were collected.Among 84 patients,42 undergoing transabdominal laparoscopic-assisted radical gastectomy (LARG) were allocated into LARG group and 42 undergoing transabdominal open radical gastectomy (ORG) were allocated into ORG group.Observation indicators:(1) comparison of intraoperative and postoperative recovery situations between groups;(2)comparison of follow-up and survival situations between groups;(3) prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival situations,tumor recurrence and metastasis of patients up to January 2018.Measurement data with normal distribution were representde as-x±s,and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the ehi-square test or Fisher exact probability.Ordinal data were compared between groups using the Mann-Whitney U nonparametric test.The survival rate and curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival and univariate analyses.Multivariate analysis was done by COX proportional hazard model.Results (1) Comparison of intraoperative and postoperative recovery situations between groups:patients with Siewert type Ⅱ and Ⅲ AEG in the LARG and ORG group underwent successful transabdominal radical resection,without conversion to thoracotomy.All patients in the LARG group underwent esophagojejunostomy with circular stapler device,38 and 4 patients in the ORG group underwent esophagojejunostomy with circular stapler and linear cut stapler respectively.Operation time,volume of intraoperative blood loss,length of incision,time of postoperative analgesia,cases with anastomotic bleeding,anastomotic leakage,abdominal bleeding,incisional infection,pulmonary infection,abdominal infection and reflux esophagitis of grade Ⅰ ～ Ⅱ postoperative complications and duration of postoperative stay were respectively (261±50)minutes,(119±111)mL,(7.8±1.6)cm,(2.1±1.3)days,1,1,0,0,1,0,0,(12.8 ± 1.9) days in LARG group and (216 ± 52) minutes,(230± 178) mL,(17.3± 1.8) cm,(3.4±1.2)days,2,0,2,2,2,1,2,(18.4±15.3)days in ORG group,with statistically significances between groups (t =2.357,2.960,2.195,2.013,x2 =5.486,t =2.125,P＜0.05).All patients with complications were improved by symptomatic treatment.(2) Comparison of follow-up and survival situations between groups:81 of 84patients including 41 in LARG group and 40 in ORG group were followed up for 6-48 months,with a median time of 29 months.The postoperative 2-year overall and tumor-free survival rates were respectively 85.1％ and 82.1％ of 41 patients in LARG group and 83.1％ and 79.3％ of 40 patients in ORG group,with no statistically significance between groups (x2 =0.013,0.049,P＞0.05).(3) Prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection:results of univariate analysis showed that tumor diameter,tumor TNM staging,tumor T staging,tumor N staging and postoperative adjuvant chemotherapy were related factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (x2 =8.349,14.376,9.732,17.250,8.012,P＜0.05).Results of multivariate analysis showed that tumor TNM staging and postoperative adjuvant chemotherapy were independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (risk ratio =4.305,0.031,95％ confidence interval:1.858-9.977,0.004-0.246,P＜0.05).Conclusions Transabdominal laparoscopicassisted radical resection for AEG is safe and feasible,with advantage of minimally invasiveness,having equivalent long-term effects compared to open surgery.Tumor TNM staging and postoperative chemotherapy are independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.

The majority of cervical spine injuries in children occur in the upper cervical spine, of which odontoid fracture is the most common. Odontoid fracture in children is a very insidious injury. Due to the unclear language and incompatible physical examination, the disease is often missed diagnosis. Because the child axis is still in the developmental segment, including 4 synchondrosis and 6 ossification centers, there are obvious anatomical and biological differences between the child odontoid fracture and the adult. Therefore, the choice of treatment is different from that of adults. This article will introduce the development of odontoid in children, and summarize the injury characteristics, clinical classification and treatment of odontoid fracture in children.

Objective:To investigate the application value of transanal endoscopic partial intersphincteric resection for ultra-low rectal cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 9 ultra-low rectal cancer patients undergoing transanal endoscopic partial intersphincteric resection at the First Affiliated Hospital of Xiamen University from December 2017 to August 2020 were collected. There were 8 males and 1 female, aged from 39 to 62 years, with a median age of 58 years. Observation indicators: (1) surgical and postoperative situations; (2) postoperative pathological examination; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative tumor local recurrence and distant metastasis, survival of patients, ileostomy closure, anus function at 3 months after ileostomy closure, male urinary and sexual function and female sexual function at 6 months after rectal surgery. The follow-up was up to February 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1)Surgical and postoperative situations: all 9 patients underwent surgery successfully, without conversion to open surgery. Seven of the 9 patients underwent transanal endoscopic partial intersphincteric resection and the rest of 2 patients with tumor close to the dentate line underwent transanal endoscopic modified partial intersphincteric resection. The operation time and volume of intraoperative blood loss of 9 patients were (267±48)minutes and 50 mL(range, 30?60 mL), respectively. Five of the 9 patients underwent transanal specimen extraction, and 4 patients underwent specimen extraction by an abdominal incision. All 9 patients underwent transanal hand-sewn coloanal anastomosis and protective ileostomy, and two pelvic drainage tubes were indwelled. Transanal drainage tube was placed after anastomosis in 3 of 9 patients. Three cases had intraoperative adverse events and there were no intraoperative adverse event reported in the remaining 6 cases. The time to postoperative initial stoma exhausting and time to postoperative first semi-liquid food intake of 9 patients were 3 days(range, 2?4 days) and 5 days(range, 4?7 days), respectively. One case had Clavien-Dindo grade Ⅰ complication and 2 cases had Clavien-Dindo grade Ⅱ complication during postoperative 30 days and the rest of 6 cases had no postoperative complication. No anastomotic stricture, hemorrhage or urinary retention occurred in 9 patients. The duration of postoperative hospital stay and cost of hospitalization of 9 patients were 11 days(range, 9?23 days) and (6.8±1.3)×10 4 yuan, respectively. (2) Postoperative pathological examination: the diameter of tumor, the distance of distal resection margin, the number of lymph node dissected and the number of positive lymph node of 9 patients were (3.2±1.4)cm, 0.6 cm(range, 0.5?1.5 cm), 17±7 and 0(range, 0?7), respectively. The tumor histopathological type was adenocarcinoma with negative tumor nodule and nerve infiltration in all 9 patients. Only 1 case of 9 patients was found vascular tumor thrombus. The surgical specimens of all 9 patients showed negative for distal and circumferential margins and complete mesorectum. Results of postoperative pathological TNM staging showed that of 6 cases with preoperative T1-T2 staging tumors, 3 cases were classified as pT2N0M0 stage, and 3 cases were classified as pT2N1M0 stage, pT2N2M0 stage or pT3N1M0 stage, respectively. Three cases with preoperative T3 staging tumors were classified as ypT0N0M0 stage, ypT2N0M0 stage or ypT3N0M0 stage, respectively. (3) Follow-up: all 9 patients were followed up for 6 to 13 months, with a median follow-up time of 9 months. No local recurrence, distant metastasis or tumor-related death was found during follow-up. Of the 9 patients, only 1 case did not receive stoma closure and undergo anus function assessment, and the rest of 8 cases underwent stoma closure. Results of postoperative anus function assessment showed 5 cases of accessibility, 2 cases of mild impairment and 1 case of severe impairment. Results of urogenital function assessment showed 6 cases of the 8 male patients of mild impairment, 1 case of moderate impairment and 1 case of severe impairment in micturition function, respectively, and 3 cases of accessibility, 2 cases of mild impairment and 3 cases of moderate impairment in sexual function, respectively. The female patient underwent accessibility of sexual function and the six-item version of the female sexual function index was 25. Conclusion:Transanal endoscopic partial intersphincteric resection can be used for the treatment of ultra-low rectal cancer.
