RESUMO

To summarize the progress in BNCT dose verification method in the world and discusses their development prospects. Boron neutron capture therapy (BNCT) utilizes the specific capture reaction between the neutrons and boron drugs enriched in tumor cells to selectively kill tumor cells. In order to verify the accuracy of the radiotherapy plan and ensure the therapeutic effect on patients, it is necessary to measure the dose before treatment and compare the experimental radiation dose with the planned dose. The current BNCT dose measurement method mainly include point dose measurement method based on ionization chambers, thermoluminescence dosimeters and activation foils, two-dimensional dose measurement method based on films, and three-dimensional dose measurement method based on gel dosimeters.

RESUMO

Background@#and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. @*Methods@#This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. @*Results@#Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). @*Conclusion@#In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.

RESUMO

Objective: To explore the imaging evaluation of cerebrospinal fluid (CSF) otorrhea associated with inner ear malformation (IEM) in children. Methods: The clinical data of 28 children with CSF otorrhea associated with IEM confirmed by surgical exploration in Beijing Children's Hospital, from Nov, 2016 to Jan, 2021, were analyzed retrospectively,including 16 boys and 12 girls, aged from 8-month to 15-year and 8-month old, with a median age of 4-year old. The shapes of stapes were observed during the exploration surgery, and the imaging features of temporal bone high resolution CT(HRCT) and inner ear MRI pre- and post-operation were analyzed. Results: In 28 children with CSF otorrhea, 89.3%(25/28) had stapes footplates defect during exploration. Preoperative CT showed indirect signs such as IEM, tympanic membrane bulging, soft tissue in the tympanum and mastoid cavity. IEM included four kinds: incomplete partition type I (IP-Ⅰ), common cavity (CC), incomplete partition type Ⅱ (IP-Ⅱ), and cochlear aplasia (CA); 100%(28/28) presented with vestibule dilation; 85.7%(24/28) with a defect in the lamina cribrosa of the internal auditory canal. The direct diagnostic sign of CSF otorrrhea could be seen in 73.9%(17/23) pre-operative MRI: two T2-weighted hyperintense signals between vestibule and middle ear cavity were connected by slightly lower or mixed intense T2-weighted signals, and obvious in the coronal-plane; 100%(23/23) hyperintense T2-weighted signals in the tympanum connected with those in the Eustachian tube.In post-operative CT, the soft tissues in the tympanum and mastoid cavity decreased or disappeared as early as one week. In post-operative MRI, the hyperintense T2-weighted signals of tympanum and mastoid decreased or disappeared in 3 days to 1 month,soft tissues tamponade with moderate intense T2-weighted signal were seen in the vestibule in 1-4 months. Conclusions: IP-Ⅰ, CC, IP-Ⅱ and CA with dilated vestibule can lead to CSF otorrhea. Combined with special medical history, T2-weighted signal of inner ear MRI can provide diagnostic basie for most children with IEM and CSF otorrhea.HRCT and MRI of inner ear can also be used to evaluate the effect of surgery.

RESUMO

OBJECTIVE@#To explore the clinical outcomes of anteromedial combined with lateral locking plate for complex proximal humeral fractures in the eldery.@*METHODS@#From June 2018 to October 2020, 30 patients who underwent surgical treatment for Neer grade 3 to 4 proximal humeral fractures, including 8 males and 22 females, aged from 51 to 78 years old with an average of (61.5±7.5) years old. Of them, 15 patients had fractures fixed with anteromedial combined with lateral locking plate(ALLP group), whereas 15 received internal fixation with proximal humerus locking plate only(PHLP group). The clinical data, simple shoulder test (SST), humeral head height loss, varus angle and shoulder range of motion were compared between the two groups.@*RESULTS@#All fractures were healed. The follow-up time ranged from 12 to 24 months, with an average of(14.3±2.9) months. The operation time of ALLP group was longer than that of PHLP group (P<0.05). There was no significant difference in intraoperative blood loss between the two groups (P>0.05). There was no significant difference in SST score between the two groups at 1, 3 and 12 months after operation (P>0.05). In terms of radiographic measurement, there was no significant difference in humeral head height loss and varus angle between the two groups at 1 and 3 months after operation (P>0.05). At 12 months after operation, the height loss and varus angle of humeral head in ALLP group were lower than those in PHLP group (P<0.05). In shoulder range of motion, the range of forward elevation in ALLP group was larger than that in PHLP group 1 year after operation(P<0.05). There was no significant difference in external rotation between the two groups.@*CONCLUSION@#Anteromedial combined with lateral locking plate in the treatment of complex proximal humeral fractures in the elderly can increase the stability of the medial column and obtain a good fracture prognosis. But there are also disadvantages such as longer operation time, so it should be individualized according to the fracture type of the patient.

RESUMO

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

RESUMO

Objective:To study the use of primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck in pancreaticoduodenectomy (PD).Methods:The clinical data of 21 patients who were treated with primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck in PD at Beijing Chaoyang Hospital Affiliated, West Campus, Capital Medical University, Rizhao Hepatobiliary-pancreatic-splenic Surgery Research Institute, Binzhou Second People’s Hospital, Chaoyang Central Hospital from February 2022 to May 2022 were retrospectively analyzed. There were 12 males and 9 females, with ages ranging from 31.0 to 82.0 years (median age 63.0 years). The success rates of linear stapling at pancreatic neck, time of pancreaticojejunostomy, postoperative complications, pancreatic fistula risk score, and length of hospital stay were studied.Results:Among the 21 patients, there were 3 patients who underwent open PD and 18 patients who underwent laparoscopic PD. Primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck was successfully carried out in all these patients. The success rate was 100.0%. The success rate of finding pancreatic ducts at the pancreatic stumps and inserting an drainage tube was 100.0%(21/21). In the 3 patients who underwent open PD, the operation time were 230.0, 245.0 and 250.0 minutes respectively. The time for completing pancreaticojejunostomy were 12.0, 13.0 and 12.0 minutes respectively. The estimated blood loss were 300.0, 450.0 and 600.0 ml respectively. The length of hospital stay were 14.0, 15.0 and 21.0 days. In the 18 patients who underwent laparoscopic PD, the operation time was (295.9±14.5) min, the time for constructing pancreaticojejunostomy was (22.3±1.5) min, the blood loss was (180.0±40.0) ml, the length of hospital stay ranging from 8.0 to 16.0 days (median 10.5 days). Among all the 21 patients, the pancreatic fistula risk score was (4.7±1.5). Postoperative acute pancreatitis occurred in 3 patients (14.3%), delayed gastric emptying occurred in 4 patients (19.0%), and all of them recovered after conservative treatment. There was no postoperative bleeding, nosocomial infection, grade B and C postoperative pancreatic fistula or perioperative death.Conclusion:The continuous single-layer pancreaticojejunostomy after linear stapler closure of the pancreatic neck was safe, reliable, simple and technically easy. It has the potential to prevent clinical postoperative pancreatic fistula and pancreaticojejunostomy bleeding. It is worth to popularize this surgical procedure.

RESUMO

Objective:To investigate the local consistency of inferior colliculus and ventrolateral orbital cortex by resting-state functional magnetic resonance imaging (fMRI) in rats with noise induced deafness and its relationship with anxiety- and depression-like behavior.Methods:Twenty-four clean grade male four-weeks old SD rats were randomly divided into noise group and control group with 12 rats in each group.Rats in the noise group were exposed to 122 dB broadband strong noise for 2 hours to induce severe bilateral hearing loss, while rats in the control group were placed in a quiet environment. Hearing thresholds were assessed by auditory brainstem response (ABR) test. The open field test (OFT) was conducted to examine anxiety-depression related behavior, and the local consistency in the rat brain was evaluated by fMRI.SPM12 software was used to process fMRI data, and Pearson correlation analysis was conducted by SPSS 22.0 software to calculate the correlation between fMRI data and behavior.Results:The results of ABR showed that the full band hearing threshold of rats in the noise group was higher than that of rats in the control group ((85.417±6.463) dB, (20.083±8.853) dB, t=46.168, P<0.001). And compared with control group, the rats in the noise group showed obvious anxiety-depression-like behavior in the open field test, that was, low activity level.The results of OFT showed that the total distance ((39.912±5.696) m, (47.993±10.820)m, t=-2.289, P=0.032), average moving speed ((13.306±1.900)cm/s, (15.998±3.607)cm/s, t=-2.290, P=0.032) and standing times ((13.333±5.960), (23.500±7.323), t=-3.730, P=0.001) of the rats in the noise group were all lower than those in the control group. Compared with the control group, the local consistency of hypothalamus in the noise group was significantly enhanced, while the local consistency of ventrolateral orbital cortex was significantly reduced, and the abnormal neural activity was lateralized. The correlation analysis showed that the neural activity of the inferior colliculus was negatively correlated with the total distance of rats in the noise group moving in the open field( r=-0.691, P=0.013), while the neural activity of the ventrolateral orbital cortex was not significantly correlated with the anxiety-depression-like behavior in the open field. Conclusions:The neural activity of inferior colliculus is closely related to anxious-depression behavior in rats with noise-induced deafness, while the ventrolateral orbital cortex may be related with other behaviors.

RESUMO

ObjectiveTo explore the optimal formula of Maxing Shigantang in regulating epidermal growth factor receptor(EGFR)expression and alleviating airway injury in asthmatic rats and to reveal the underlying mechanism. MethodSD male rats were randomly divided into normal group, model group, dexamethasone group (5×10-4 g·kg-1) and Maxing Shigantang 1∶0.5, 1∶1, 1∶2 groups (group A, B, C, 10 g·kg-1), with 8 rats in each group. The other groups except the normal group received nebulization of 2% acetylcholine chloride and 0.4% histamine phosphate for the modeling of asthma. One hour before modeling, the normal group and the model group were given the same amount of normal saline, and the other groups were given the same amount of corresponding drugs, once a day for 7 days. On the 7th day, the model was established and the incubation period of asthma was recorded. The rats were then immediately anesthetized, and arterial blood and tracheal tissue were collected. Enzyme-linked immunosorbent assay (ELISA) was employed to detect the levels of interleukin-2 (IL-2), interleukin-4 (IL-4), and tumor necrosis factor-α (TNF-α) in serum. Pathological sections were prepared for the observation of the pathological changes of tracheal tissues and the ultrastructure of epithelial cells in each group. Terminal-deoxynucleotidyl transferase-mediated nick-end labeling (TUNEL) was adopted to detect epithelial cell apoptosis, and in situ hybridization and Western blot were employed to determine the mRNA and protein levels of epidermal growth factor receptor (EGFR), respectively. ResultCompared with the model group, groups A, B and C prolonged the incubation period of asthma (P<0.05,P<0.01). Compared with the control group, the model group showed declined IL-2 level (P<0.01), risen IL-4 and TNF-α levels (P<0.05,P<0.01), increased airway pathology score, collagen volume fraction, and airway epithelial cell apoptosis index (P<0.01), and up-regulated mRNA and protein levels of EGFR in trachea tissue (P<0.01). Compared with the model group, group A showed increased IL-2 level (P<0.05) and declined IL-4 (P<0.05,P<0.01) level, and group B showed declined IL-4 level (P<0.05). The level of TNF-α in groups A, B, and C declined compared with that in the model group (P<0.01). Maxing Shigantang repaired the tracheal tissue to different degrees (P<0.05). Among the three groups, group A inhibited tracheal fibrosis (P<0.05) and had the most significant effect of repairing the ultrastructural changes of airway epithelial cells. Groups A, B and C all inhibited the apoptosis of airway epithelial cells (P<0.05). All the three groups inhibited the up-regulation of EGFR mRNA level (P<0.05,P<0.01), and groups B and C inhibited the up-regulation of EGFR protein level (P<0.05,P<0.01). ConclusionMaxing Shigantang can inhibit the abnormal changes of airway epithelial structure, alleviate airway injury, and can down-regulate the expression of EGFR in the tracheal tissue of asthma model rats. In this study, the optimal compatibility of Maxing Shigantang to repair airway epithelial injury in asthmatic rats was group A, with the Ephedrae Herba-Armeniacae Semen Amarum-Glycyrrhizae Radix et Rhizoma-Gypsum Fibrosum ratio of 1∶0.5∶4∶1.

RESUMO

Objective: Autologous peripheral blood stem cells (PBSC) derived from bone marrow can promote liver regeneration and improve the liver function of patients, but there are few studies on its effect on the long-term outcomes in patients with decompensated cirrhosis. Based on previous work, this study observed the clinical outcomes of PBSC treatment in patients with decompensated cirrhosis for 10 years, in order to provide more data support for the safety and efficacy of stem cells in clinical applications. Methods: Data of patients with decompensated liver cirrhosis who completed PBSC treatment in the Department of Gastroenterology of the First Affiliated Hospital of Air Force Military Medical University from August 2005 to February 2012 were included. The follow-up endpoint was death or liver transplantation, and patients who did not reach the follow-up endpoint were followed-up for at least 10 years. The patients with decompensated liver cirrhosis who met the conditions for PBSC treatment but did not receive PBSC treatment in our hospital during the same period were used as controls. Results: A total of 287 cases with decompensated liver cirrhosis had completed PBSC treatment, and 90 cases were lost to follow-up within 10 years after surgery. A total of 151 cases with complete survival follow-up data were included in the control group. There were no statistically significant differences in baseline information such as gender, age, etiological composition and liver function score between the two groups. The 10-year survival rate was higher in PBSC than control group (37.56% vs. 26.49%, P<0.05). Cholinesterase, albumin, international normalized ratio, Child-Turcotte-Pugh score, model for end-stage liver disease score, and other indicators were gradually recovered within 3 months to 1 year after PBSC treatment, and stabilized at a more desirable level in the long-term after follow-up for up to 10 years. There was no statistically significant difference in the incidence of liver cancer between the two groups (25.22% vs.31.85%, P=0.267). The age of onset of hepatocellular carcinoma was later in PBSC than control group [(56.66±7.21) years vs. (52.69±8.42) years, P<0.05]. Conclusions: This long-term observational follow-up study of more than ten years confirms that PBSC treatment can bring long-term benefits to patients with decompensated cirrhosis, with good long-term safety, thus providing more data support on the safety and efficacy of stem cells for clinical applications.

RESUMO

Objective: To investigate the clinical efficacy of long-segment pedicle screw reduction and internal fixation combined with kyphoplasty in the treatment of stage Ⅲ reducible Kummell disease. Methods: The clinical data of 32 patients with stage Ⅲ reducible Kummell disease treated at the Department of Orthopedics, Sir Run Run Shaw Hospital, Zhejiang University College of Medicine from January 2012 to March 2017 were analyzed retrospectively.There were 7 males and 25 females,aged (71.8±6.7)years(range:61 to 86 years).The injured segment was T10 in 1 patient,T11 in 8 patients,T12 in 13 patients,L1 in 7 patients,L2 in 2 patients and L3 in 1 patient.Preoperative American spinal injury association(ASIA) classification of patients all showed grade D.Bone mineral density (BMD),spinal X-ray,CT and MRI were examined before operation.All patients were treated with postural reduction, long-segment pedicle screw reduction and internal fixation combined with kyphoplasty.The operation time,intraoperative blood loss,length of stay and postoperative complications were recorded.The visual analogue scale (VAS) and Oswestry dysfunction index (ODI) as well as the BMD of hip were collected before and after operation.The Cobb angle of involved segment kyphosis and the height of anterior edge of diseased vertebrae were measured before operation,3 days and 12 months after operation.CT-related parameters were measured before and 3 days after operation,including sagittal anterior and posterior diameter of spinal canal,cross-sectional anterior and posterior diameter of spinal canal and cross-sectional spinal canal area.Paired sample t test and repeated measures were used to compare the data before and after operation. Results: All patients received the operation successfully.The operation time was (131.3±16.9) minutes (range:95 to 180 minutes),the blood loss was (82.5±27.1) ml (range:50 to 150 ml),and the length of stay was (8.3±2.4) days (range:5 to 14 days).All patients were followed up for more than 12 months.The VAS decreased gradually at 3 days,3 months,6 months and 12 months after operation,and the differences were statistically significant compared with the VAS before surgery (all P<0.01).ODI at 3,6 and 12 months after surgery was significantly improved compared with that before surgery(All P<0.01).The CT-related parameters at 3 days after operation were significantly higher than those before operation (All P<0.05).At 12 months after surgery,the Cobb angle decreased from (35.2±7.6) ° preoperatively to (4.3±1.7) ° (t=22.630,P<0.01),the height of anterior edge of diseased vertebrae increased from (4.3±1.0) mm preoperatively to (16.9±2.5) mm(t=-25.845,P<0.01),the bone mineral density of hip increased from -(2.2±0.6) preoperatively to -(2.8±0.6)(t=-0.040,P<0.01).Up to the last follow-up,2 patients had distal pedicle screw loosening, 1 patient had proximal junctional kyphosis,and there was no new vertebral fracture. Conclusions: Based on postural reduction,long-segment pedicle screw reduction and internal fixation combined with kyphoplasty is a safe and effective treatment method for stage Ⅲ reducible Kummell disease,which can reconstruct the stability of the diseased vertebrae.Postoperative standard anti-osteoporosis treatment is the basis to ensure the efficacy.

RESUMO

Objective:To observe and preliminary investigate the influencing factors of exudative retinal detachment in patients with severe preeclampsia (S-PE) and its influence on pregnancy outcome.Methods:A total of 89 patients of S-PE patients diagnosed in Department of Obstetrics in The Third Central Hospital of Tianjin from July 2018 to June 2020 were included in this study. According to whether the patients were complicated with exudative retinal detachment, they were divided into retinal detachment group (43 cases) and non retinal detachment group (46 cases). All patients underwent direct ophthalmoscopy, and those with suspected or definite retinal detachment underwent optical coherence tomography or B-mode ultrasonography. The age, course of disease, body mass index, systolic blood pressure, diastolic blood pressure, laboratory serum albumin level, 24 h urinary protein, platelet count, mean platelet volume, platelet distribution width and serum uric acid content were collected. The average age ( t=-1.01), body mass index ( t=-1.799), course of disease ( t=-1.657) and constituent ratio of primipara and multipara in the two groups were compared ( χ2=1.411), the difference was not statistically significant ( P>0.05). The end of pregnancy time, systemic complications, fetal outcomes and neonatal Apgar scores were analyzed, retrospectively. Independent sample t test was used to compare the quantitative data between the two groups; Chi square test was used to compare qualitative data. Binary logistic regression analysis to screen the influencing factors of exudative retinal detachment in S-PE. Results:Systolic blood pressure and diastolic blood pressure were higher in the retinal detachment group than in the non retinal detachment group, and the difference was statistically significant ( t=2.087, 2.810; P=0.040, 0.006). Serum albumin ( t=-10.404), 24-hour urinary protein quantification ( t=6.401), blood uric acid ( t=3.910), platelet count ( t=-6.124) and platelet distribution width ( t=2.992) were compared between the two groups, and the differences were statistically significant ( P<0.05). There were 30 (69.77%, 30/43) cases in retinal detachment group and 14 (30.43%, 14/46) cases in non retinal detachment group with severe systemic complications; The average time of ending pregnancy was 34.66±3.29 and 38.25±1.62 weeks; The average Apgar scores at birth were 7.28±3.40 and 9.46±1.59. The incidence of severe systemic complications in two groups ( χ2=13.755), the end of pregnancy time ( t=-6.448), Apgar score at birth ( t=-3.824), the differences were statistically significant ( P=0.000、0.000、0.000). Fetal distress and death were 8 (18.60%, 8/43), 7 (16.28%, 7/43) and 7 (15.22%, 7/46), 1 (2.17%, 1/46) in retinal detachment group and non retinal detachment group respectively. There was no significant difference in the incidence of fetal distress between the two groups ( χ2=0.182, P=0.670). The difference of fetal mortality was statistically significant ( P= 0.027). Logistic regression analysis showed that serum albumin and uric acid were associated with exudative retinal detachment in patients with S-PE ( P<0.05). Conclusions:Serum albumin and uric acid are the influencing factors of exudative retinal detachment in patients with S-PE. Patients with exudative retinal detachment are prone to adverse pregnancy outcomes.

RESUMO

Objective:To explore the perivenous blocking management strategy for portal vein-superior mesenteric vein (PSMV) resection and reconstruction and its effect on postoperative complications in patients undergoing pancreaticoduodenectomy (PD).Methods:The data of 137 patients with pancreatic cancer treated with PD in Beijing Chaoyang Hospital Affiliated to Capital Medical University, Chaoyang Central Hospital, the Second Hospital of Chaoyang, Rizhao Central Hospital, the Second People's Hospital of Binzhou from January 2010 to December 2020 were collected. There were 83 males and 54 females with an average age of 61.8 years. There were 42 patients in the reconstruction group and 95 patients in the control group. The main intraoperative indexes and postoperative complications were compared between the two groups with the aim to review our experience in PSMV resection and reconstruction by using the perivenous blocking management strategy.Results:PD was successfully completed in 137 patients in the reconstruction group, the PSMV blocking time was 15-120 min, with a median of 30 min. The operation time 380 (330, 465) min, intraoperative blood loss 725 (500, 1000) ml, and postoperative hospital stay 21.0 (16.0, 28.0) d in the reconstruction group were significantly higher than those of control group [305 (280, 340) min, 400 (300, 500) ml and 18.0 (14.0, 24.5) d] (all P<0.05). The reoperation rate and perioperative mortality were 4.8% (2/42) and 2.4% (1/42) in the reconstruction group, while 2.1% (2/95) and 1.0% (1/95) in the control group, respectively. There was no significant difference between the two groups (both P>0.05). The incidence of pancreatic fistula, peritoneal effusion and infection, pulmonary infection of the reconstruction group was significantly higher than those of the control group ( P<0.05). There was no significant difference in the incidence of postoperative bleeding, delayed gastric emptying, biliary fistula, incision infection, reoperation between the two groups ( P>0.05). Conclusions:PSMV resection and reconstruction significantly increased the incidences of complication after PD, including pancreatic fistula, peritoneal effusion/infection and pulmonary infection. The perivenous blocking management strategy significantly promoted smooth postoperative recovery and effectively reduced morbidity rates of postoperative bleeding and mortality after PSMV resection and reconstruction in PD.

RESUMO

Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a rare and poorly differentiated tumor with poor prognosis. Although radical surgical treatment is the most preferred treatment for GEP-NEC, postoperative recurrence rate is still high. Many patients diagnosed at the late stage lost the chances to receive the surgery treatment. Therefore, systemic chemotherapy plays a particularly important role in the comprehensive treatment of GEP-NEC. The purpose of this paper is to systematically summarize and review the research progress of GEP-NEC systemic chemotherapy.

RESUMO

Objective:To investigate the methyl-CpG-binding protein 2 (MeCP2) expression in specimens of pancreas cancer tumor and para-cancerous tissues and its prognostic value.Methods:The tissue microarray and immunohistochemistry were used to examine the MeCP2 expression in 59 cases of pancreatic cancer tumor tissues and 53 adjacent normal tissues. The correlation between the MeCP2 expression and clinicopathological characteristics of pancreas cancer patients was analyzed. Furthermore, the survival curve was drawn by Kaplan-Meier method and the Cox regression hazards model was used to study the prognostic value of MeCP2 expression in pancreas cancer.Results:The MeCP2 positive expression rate in 59 pancreas cancer tumor tissues was 47.5%, which was 67.9% in 53 adjacent tissues. The MeCP2 positive expression rate in adjacent tissues was obviously higher than that in pancreatic cancer tissues, and the difference was statistically significant ( P<0.05). The MeCP2 positive expression was significantly associated with pathological grade and lymph node metastasis(both P<0.05). The overall survival in patients positive for the MeCP2 expression was longer than that in those with negative MeCP2 expression( P<0.05). Cox multivariate analysis demonstrated that the level of MeCP2 expression was an independent predictor for prognosis in patients with pancreas cancer. Conclusions:MeCP2 is obviously positively expressed in para-cancerous tissues, but was lowly expressed in pancreatic cancer, indicating that MeCP2 detection can help to evaluate the prognosis of pancreatic cancer patients.

RESUMO

BACKGROUND@#Thyroid dysfunction is associated with cardiovascular diseases. However, the role of thyroid function in lipid metabolism remains partly unknown. The present study aimed to investigate the causal association between thyroid function and serum lipid metabolism via a genetic analysis termed Mendelian randomization (MR).@*METHODS@#The MR approach uses a genetic variant as the instrumental variable in epidemiological studies to mimic a randomized controlled trial. A two-sample MR was performed to assess the causal association, using summary statistics from the Atrial Fibrillation Genetics Consortium (n = 537,409) and the Global Lipids Genetics Consortium (n = 188,577). The clinical measures of thyroid function include thyrotropin (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) levels, FT3:FT4 ratio and concentration of thyroid peroxidase antibodies (TPOAb). The serum lipid metabolism traits include total cholesterol (TC) and triglycerides, high-density lipoprotein, and low-density lipoprotein (LDL) levels. The MR estimate and MR inverse variance-weighted method were used to assess the association between thyroid function and serum lipid metabolism.@*RESULTS@#The results demonstrated that increased TSH levels were significantly associated with higher TC (β = 0.052, P = 0.002) and LDL (β = 0.041, P = 0.018) levels. In addition, the FT3:FT4 ratio was significantly associated with TC (β = 0.240, P = 0.033) and LDL (β = 0.025, P = 0.027) levels. However, no significant differences were observed between genetically predicted FT4 and TPOAb and serum lipids.@*CONCLUSION@#Taken together, the results of the present study suggest an association between thyroid function and serum lipid metabolism, highlighting the importance of the pituitary-thyroid-cardiac axis in dyslipidemia susceptibility.

RESUMO

Colorectal liver metastases (CRLM) is challenging for colorectal cancer therapy, and is also the main cause of death in colorectal cancer patients. In recent years, radiofrequency ablation (RFA) as one of the local treatments for liver tumors, was used in the comprehensive treatment of CRLM in an exploratory manner, expressing its advantages of minimally invasive, feasible, safe, effective and repeatable treatment. This article reviewed the research progress of RFA and RFA combined with other therapy treatments in different stages of CRLM, in order to provide more choices for CRLM comprehensive treatment.

RESUMO

Objective:To study the results of using a sequential menagement of conservative treatment, percutaneous transhepatic cholangial drainage(PTCD), laparoscopic cholecystectomy(LC) combined with laparoscopic common bile duct exploration(LCBDE) and primary duce closure(PDC) in patients with cholecystolithiasis and common bile duct stone(CBDS) who presented with acute cholangitis.Methods:The clinical data of 397 patients with CBDS and cholecystolithiasis who presented with acute cholangitis from January 2015 to August 2020 were retrospectively analyzed, including 230 patients from the West Campus, Beijing Chaoyang Hospital, Capital Medical University, 95 patients from the Second People's Hospital of Binzhou and 72 patients from Rizhao Central Hospital. Conservative treatment, PTCD and LC+ LCBDE+ PDC were used sequentially. The interval between PTCD and LCBDE, the decrease of serum total bilirubin and alanine aminotransferase after PTCD, the operative time of LC+ LCBDE+ PDC, and the intraoperative blood loss were analyzed. Postoperative indwelling time of abdominal drainage tube and PTCD tube time, postoperative hospital stay, postoperative complications, etc.Results:These were 15 males and 18 femals with the mean age of 57.5 years old. The mean serum total bilirubin and alanine aminotransferase levels decreased from (148.3±36.8) μmol/L and (172.6±26.9) U/L before PTCD to (32.6±5.9) μmol/L and (45.7±7.2) U/L after PTCD, respectively. The interval between PTCD and LCBDE was (25.3±2.6) d. The operation time of LC+ LCBDE+ PDC was (95.4±14.2) min. The intraoperative blood loss was (35.2±9.5 )ml and the mean postoperative hospital stay was (12.4±3.5) d. The postoperative indwelling time of abdominal drainage tubes and PTCD tubes were (10.6±2.3) d and (25.8±4.7) d, respectively. After surgery, bile leakage occurred in 3 patients (9.1%), abdominal hemorrhage in 1 patient (3.0%), biliary bleeding in 1 patient (3.0%), navel incision infection in 1 patient (3.0%), lower common bile duct stenosis in 2 patients (6.1%). All complications responded well to conservation treatment.Conclusions:Sequential treatment using conservative treatment, PTCD combined with LC+ LCBDE+ PDC in patients with cholecystolithiasis and CBDS who presented with acute cholangitis was safe, and efficacious using the minimally invasive approach. This approach is worth promoting to other centers.

RESUMO

Objective:To study the impact of Roux-en-Y reconstruction with isolated pancreatic drainage (RYR) on delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD).Methods:The data of 203 patients who underwent PD at 5 clinical centers from January 2014 to June 2020 were collected. According to the method of reconstruction of the digestive tract, the patients were divided into the RYR group ( n=88) and the conventional loop reconstruction (CLR) group ( n=115). The incidence and severity of DGE were compared between groups. The risk factors of clinically relevant DGE (CR-DGE) after PD were analysed by univariate and multivariate analyses. Results:Of 203 patients, there were 124 males and 79 females, aged (61.6±10.2) years. The overall incidence of DEG was 27.6% (56/203). The incidence of CR-DGE in the RYR group was significantly lower than that in the CLR group [13.6%(12/88) vs 26.1%(30/115), P=0.030]. Patient age of more than 65 years ( OR=2.966, 95% CI: 1.162-8.842, P=0.024), clinically relevant pancreatic fistula ( OR=3.041, 95% CI: 1.122-8.238, P=0.029), ascites and abdominal infection ( OR=10.000, 95% CI: 2.552-39.184, P=0.001), and CLR ( OR=3.206, 95% CI: 1.162-8.842, P=0.024) were identified as independent risk factors for CR-DGE. The duration of hospitalization and hospital expenditure of patients were significantly increased in the CR-DGE group ( P<0.05). Conclusions:Patients over 65 years with clinically relevant pancreatic fistula, with ascites or abdominal infection after operation, had a higher evidence of CR-DGE. Roux-en-Y reconstruction with isolated pancreatic could helped to decrease the incidence of CR-DGE after PD.
