The safety and efficacy of balanced crystalloid vs. normal saline in non-cardiac surgeries - A systematic review and meta-analysis.

OBJECTIVE: Balanced crystalloid and normal saline are routinely used in clinical anesthesia, but their safety and efficacy in non-cardiac surgeries are still unclear. MATERIALS AND METHODS: PubMed, Embase, Web of Science, Cochrane Library, Wanfang, and CNKI, from January 1980 to March 2023, were searched. Studies comparing balanced crystalloid (BC) with normal saline (NS) during non-cardiac surgeries were included. The primary outcomes were clinical outcomes (acidosis, renal insufficiency, and mortality), and the secondary outcomes were pH value, Na+, Cl- and creatinine levels, and vasopressor requirement. RESULTS: Forty-three RCTs were included in this meta-analysis. Low evidence revealed that the development of acidosis was lower in the BC group than in the NS group (OR: 0.05, 95% CI: 0.01-0.43, I2=80.8%, p=0.00), and no between-group difference exists in renal insufficiency and mortality. At the end of surgery and on postoperative day 1 (POD 1), the pH value was higher, and the levels of Na+ and Cl- were lower in the BC group. No between-group difference exists in creatinine level and vasopressor requirement. CONCLUSIONS: Perioperative balanced crystalloids can maintain the stability of acid-base and electrolyte balance and reduce acidosis compared with saline, but they cannot reduce postoperative renal insufficiency and mortality.

Deteriorated bone microarchitecture caused by sympathetic overstimulation in pheochromocytoma and paraganglioma.

PURPOSE: Despite the potentially destructive effect of sympathetic activity on bone metabolism, its impact on bone microarchitecture, a key determinant of bone quality, has not been thoroughly investigated. This study aims to evaluate the impact of sympathetic activity on bone microarchitecture and bone strength in patients with pheochromocytoma and paraganglioma (PPGL). METHODS: A cross-sectional study was conducted in 38 PPGL patients (15 males and 23 females). Bone turnover markers serum procollagen type 1 N-terminal propeptide (P1NP) and ß-carboxy-terminal crosslinked telopeptide of type 1 collagen (ß-CTX) were measured. 24-h urinary adrenaline (24hUE) and 24-h urinary norepinephrine levels (24hUNE) were measured to indicate sympathetic activity. High-resolution peripheral quantitative computed tomography (HR-pQCT) was conducted to evaluate bone microarchitecture in PPGL patients and 76 age-, sex-matched healthy controls (30 males and 46 females). Areal bone mineral density (aBMD) was measured by dual-energy X-ray absorptiometry (DXA) simultaneously. RESULTS: PPGL patients had a higher level of ß-CTX. HR-pQCT assessment revealed that PPGL patients had notably thinner and more sparse trabecular bone (decreased trabecular number and thickness with increased trabecular separation), significantly decreased volume BMD (vBMD), and bone strength at both the radius and tibia compared with healthy controls. The deterioration of Tt.vBMD, Tb.Sp, and Tb.1/N.SD was more pronounced in postmenopausal patients compared with the premenopausal subjects. Moreover, subjects in the highest 24hUNE quartile (Q4) showed markedly lower Tb.N and higher Tb.Sp and Tb.1/N.SD at the tibia than those in the lowest quartile (Q1). Age-related bone loss was also exacerbated in PPGL patients to a certain extent. CONCLUSIONS: PPGL patients had significantly deteriorated bone microarchitecture and strength, especially in the trabecular bone, with an increased bone resorption rate. Our findings provide clinical evidence that sympathetic overstimulation may serve as a secondary cause of osteoporosis, especially in subjects with increased sympathetic activity.

[Effect of equal temperature bladder irrigation in patients with transurethral resection of prostate: A meta-analysis].

OBJECTIVE: To evaluate the effect of equal temperature bladder irrigation on bladder spasm, postoperative bleeding, vital signs and discomfort of chills in patients of transurethral resection of prostate using meta-analysis. METHODS: Several electronic databases included Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, China Biology Medicine (CBM) were searched systematically for published randomized controlled trial about equal temperature bladder irrigation in patients with transurethral resection of prostate before November 20, 2019. Two reviewers selected independently the literature in the light of the inclusion and exclusion criteria, assessed the risk of bias by quality assessment and extracted data which were consisted of clinical efficacy indexes, such as incidence of bladder spasm, severity of bladder spasm, incidence of tube plugging, amount of bladder flushing fluid, time of bladder flushing, heart rate, systolic pressure, diastolic pressure, and incidence of chills. Data were pooled using fixed-effects model or random-effects model, and the summary effect measure was calculated by risk ratio (RR) or mean difference (MD) and 95% confidence interval (95%CI). Meta-analysis was performed by Review Manager 5.3 Software. RESULTS: In the study, 13 randomized controlled trails met the requirement with a total of 2 033 patients of transurethral resection of prostate were included, of whom 1 015 were carried out with equal temperature bladder irrigation and 1 018 with room temperature bladder irrigation. The results of meta-analysis showed that incidence of bladder spasm [RR=0.51, 95%CI (0.45, 0.57), P < 0.001], severity of bladder spasm [MD=-1.61, 95%CI (-2.00, -1.23), P < 0.001], incidence of urinary blockage [RR=0.29, 95%CI (0.19, 0.44), P < 0.001], dosage of bladder irrigation [MD=-6.75, 95%CI (-7.33, -6.17), P < 0.001], time of bladder rinse [MD=-7.60, 95%CI (-11.91, -3.29), P < 0.001], heart rate [MD=-13.68, 95%CI (-15.19, -12.17), P < 0.001], systolic pressure [MD=-29.26, 95%CI (-31.92, -26.59), P < 0.001], diastolic pressure [MD=-29.36, 95%CI (-31.75, -26.98), P < 0.001], incidence of chills and discomfort [MD=0.37, 95%CI (0.31, 0.44), P < 0.001] in equal temperature group of the patients with transurethral resection of prostate had significantly statistical difference compared with room temperature group. CONCLUSION: Based on current available evidence, equal temperature bladder irrigation reduced the incidence of bladder spasm and urinary blockage, relieved bladder spasm, reduced dosage and time of bladder irrigation, and hardly affected normal vital signs and increased the patient' s comfort.

High prevalence of vertebral deformity in tumor-induced osteomalacia associated with impaired bone microstructure.

PURPOSE: Patients with tumor-induced osteomalacia (TIO) often suffer from irreversible height loss due to vertebral deformity. However, the prevalence of vertebral deformity in TIO patients varies among limited studies. In addition, the distribution and type of vertebral deformity, as well as its risk factors, remain unknown. This study aimed to identify the prevalence, distribution, type and risk factors for vertebral deformity in a large cohort of TIO patients. METHODS: A total of 164 TIO patients were enrolled in this retrospective study. Deformity in vertebrae T4-L4 by lateral thoracolumbar spine radiographs was evaluated according to the semiquantitative method of Genant. Bone microstructure was evaluated by trabecular bone score (TBS) and high-resolution peripheral QCT (HR-pQCT). RESULTS: Ninety-nine (99/164, 60.4%) patients had 517 deformed vertebrae with a bimodal pattern of distribution (T7-9 and T11-L1), and biconcave deformity was the most common type (267/517, 51.6%). Compared with patients without vertebral deformity, those with vertebral deformity had a higher male/female ratio, longer disease duration, more height loss, lower serum phosphate, higher bone turnover markers, lower TBS, lower areal bone mineral density (aBMD), lower peripheral volumetric BMD (vBMD) and worse microstructure. Lower trabecular vBMD and worse trabecular microstructure in the peripheral bone and lower spine TBS were associated with an increased risk of vertebral deformity independently of aBMD. After adjusting for the number of deformed vertebrae, we found little difference in clinical indexes among the patients with different types of vertebral deformity. However, we found significant correlations of clinical indexes with the number of deformed vertebrae and the spinal deformity index. CONCLUSION: We reported a high prevalence of vertebral deformity in the largest cohort of TIO patients and described the vertebral deformity in detail for the first time. Risk factors for vertebral deformity included male sex, long disease duration, height loss, abnormal biochemical indexes and bone impairment. Clinical manifestation, biochemical indexes and bone impairment were correlated with the number of deformed vertebrae and degree of deformity, but not the type of deformity.

Definition of large niche after Cesarean section based on prediction of postmenstrual spotting: Chinese cohort study in non-pregnant women.

OBJECTIVE: A large niche after Cesarean section (CS) is associated with long-term complications, of which postmenstrual spotting is associated positively with the size of the niche. However, the diagnosis of a large niche in the literature is inconsistent and the definition is largely subjective. The aim of this study was to generate a definition for a large niche in non-pregnant women based on the presence of postmenstrual spotting. METHODS: Women who had undergone CS in our hospital between January 2012 and June 2017 were selected randomly from our database, contacted by telephone and subsequently examined between January 2016 and June 2020. Eligible for inclusion were non-pregnant women who had their last CS more than 1 year earlier and agreed to undergo transvaginal sonography (TVS). All participants underwent examination of their CS scar by TVS (two-dimensional color Doppler) during the midfollicular phase. Niche depth, length, width, residual myometrial thickness (RMT), adjacent myometrial thickness (AMT) and ratio of niche depth/AMT were recorded. Women diagnosed with a niche, defined as an indentation at the site of the CS with a depth of at least 2 mm, were classified into two groups (symptomatic or asymptomatic) according to whether they experienced postmenstrual spotting. Logistic regression analysis was used to establish the best cut-off values for the niche parameters to predict postmenstrual spotting. A new definition was generated based on the niche parameters with the highest area under the receiver-operating-characteristics (ROC) curve (AUC) for the prediction of postmenstrual spotting. RESULTS: A total of 727 women who had a CS > 1 year earlier underwent TVS examination, of whom 263 were diagnosed with a niche (prevalence of 36.2%). Of these, 160 women experienced postmenstrual spotting and 103 were asymptomatic. The three variables with the highest AUC for prediction of postmenstrual spotting were niche depth/AMT ratio (AUC, 0.798; 95% CI, 0.745-0.852), niche depth (AUC, 0.731; 95% CI, 0.668-0.795) and RMT (AUC, 0.683; 95% CI, 0.618-0.748). Based on the best cut-offs according to ROC-curve analysis, a large niche was defined as: niche depth ≥ 0.50 cm, RMT ≤ 0.21 cm or niche depth/AMT ratio ≥ 0.56. The prevalence of a large niche according to this definition was 22.4% (163/727). The new definition had a specificity of 61.17% (95% CI, 52.34-70.41%) and sensitivity of 76.87% (95% CI, 70.28-84.16%) for a large niche. CONCLUSION: This study has provided a new definition for a large niche after CS. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

A prospective study on vulvovaginal candidiasis: multicentre molecular epidemiology of pathogenic yeasts in China.

BACKGROUND: Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES: The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS: Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS: Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS: Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

A systematic review of risk factors for postinduction hypotension in surgical patients undergoing general anesthesia.

OBJECTIVE: Clinical evidence has proved that postinduction hypotension (PIH) is very prevalent in surgical patients undergoing general anesthesia, and commonly develops within 20 min after the induction of general anesthesia. However, the risk factors for PIH are not clear till now, therefore, a systematic review of current evidence was conducted. MATERIALS AND METHODS: PubMed, Embase, Cochrane library, and Web of Science were searched for articles published in English up to June 2021. The following search items were used: postinduction, postintubation, propofol induction, anesthesia induction, general anesthesia induction, hypotension, risk factor, general anesthesia, surgery. The articles were screened using the inclusion and exclusion criteria, and the data from included studies were extracted and analyzed. RESULTS: Twelve studies were included. Seven studies reported the association between age and PIH, and six showed age was a risk factor. Five or three studies reported the association between mean arterial pressure (MAP) and PIH or between systolic blood pressure (SBP) and PIH, but the results were conflicting. Results from two studies regarding gender and PIH were conflicting. Two studies reported that weight was negatively correlated with PIH. Low baseline blood volume, emergency operation, long-term intake of the angiotensin converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) were risk factors for PIH. One study showed that ASA III-V, propofol induction, and increasing fentanyl dosage were risk factors for PIH. CONCLUSIONS: Aging, ASA III-V, emergency operation, low baseline blood volume, long-term intake of ACEI/ARB, propofol induction, and increasing fentanyl dosage are potential risk factors for PIH, while body weight gain is a protective factor. Based on the current evidence, it is difficult to determine whether baseline blood pressure or gender is associated with the development of PIH.

[Long-term efficacy and safety of simultaneous integrated boost radiotherapy in non-operative esophageal squamous cell carcinoma: a multicenter retrospective data analysis (3JECROG R-05)].

Objective: To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients. Methods: The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed. Results: The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively (P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively (P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm(3), the median survival time of SIB and No-SIB group was 34.7 and 30.3 months (P=0.155), respectively. In the patients whose GTV volume>50 cm(3), the median survival time of SIB and No-SIB group was 16.1 and 20.1 months (P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group (P<0.001). Conclusions: The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

[Efficacy analysis of the radiotherapy and chemotherapy in patients with stage â £ esophageal squamous carcinoma: a multicenter retrospective study of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG R-01F)].

Objective: To evaluate the survival and prognostic factors of radiotherapy in patient with Ⅳ stage esophageal squamous carcinoma treated with radiation or chemoradiation. Methods: The medical records of 608 patients with stage Ⅳ esophageal squamous cell carcinoma who met the inclusion criteria in 10 medical centers in China from 2002 to 2016 were retrospectively analyzed. The overall survival and prognostic factors of all patients at 1, 3 and 5 years were analyzed. Results: The 1-, 3-, 5- year overall survival (OS) rates was 66.7%, 29.5% and 24.3% in stage ⅣA patients, and 58.8%, 29.0% and 23.5% in stage ⅣB patients. There was no statistical difference between the two groups (P=0.255). Univariate analysis demonstrated that the length of lesion, treatment plan, planned tumor target volume (PGTV) dose, subsequent chemotherapy, and degrees of anemia, radiation esophagitis, radiation pneumonia were related to the prognoses of patients with Ⅳ stage esophageal carcinomas after radiotherapy and chemotherapy (P<0.05). Multivariate analysis demonstrated that PGTV dose (OR=0.693, P=0.004), radiation esophagitis (OR=0.867, P=0.038), and radiation pneumonia (OR=1.181, P=0.004) were independent prognostic factors for OS. Conclusions: For patients with stage Ⅳ esophageal squamous cell carcinoma, chemoradiotherapy followed by sequential chemotherapy is recommended, which can extend the total survival and improve the prognosis of the patients. PGTV dose more than 60 Gy has better efficacy.

[Finite element analysis of evaluating the change of the hip joint biomechanics following femoral neck shortening after cannulated screw fixation for osteoporotic femoral neck fracture].

Objective: To evaluate the stress status of femoral head and neck, screws and acetabulum caused by femoral neck shortening after internal fixation of femoral neck fracture with finite element method, and to analyze the stress of proximal femoral neck and acetabulum from the mechanical point of view. Methods: CT scan data of hip of a healthy adult female were collected. Three-dimensional reconstruction MICs and related module function simulation was used to establish the postoperative shortening model of femoral neck fracture with Pauwells angle>50°, which was treated with cannulated screws. The models were divided into four groups: normal femoral neck without shortening, shortening for 2.5 mm, shortening for 7.5 mm and shortening for 12.5 mm. The finite element analysis software MSC. Nastran2012 was used to do the mechanical analysis. The acetabulum surface, femoral head surface, proximal femur and the maximum stress, stress nephogram and other relevant data were collected. Results: The maximum tensile stress and the maximum stress at the fracture site of the femoral neck increased gradually with the increasing of shortening of femoral neck, however, the maximum compressive stress under the femoral neck and the medial cortex decreased gradually; the maximum stress on the surface of the femoral head was 14.9, 15.0, 16.3 and 16.3 MPa, respectively; the maximum stress on the surface of the acetabulum was 10.1, 10.1 and 10.5,11.7 MPa, respectively. Conclusion: The mechanical environment of the hip joint changes with femoral neck shortening. With the increasing of femoral neck shortening, the peak stress of the acetabulum increases continuously. When the femoral neck is shortened seriously, the load distribution is uneven and the complex mobility of hip joint is decreased. In addition, the change of shortening might play a role in the necrosis of femoral head.

[Prognostic analysis of definitive radiotherapy for early esophageal carcinoma(T1-2N0M0): a multi-center retrospective study of Jing-Jin-ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group].

Objective: To evaluate the prognostic factors of T1-2N0M0 esophageal squamous cell carcinoma (ESCC) treated with definitive radiotherapy. Methods: The clinical data of 196 patients with T1-2N0M0 ESCC who were treated with definitive radiotherapy in 10 hospitals were retrospectively analyzed. All sites were members of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG). Radiochemotherapy were applied to 78 patients, while the other 118 patients received radiotherapy only. 96 patients were treated with three-dimensional conformal radiotherapy (3DCRT) and 100 treated with intensity-modulated radiotherapy (IMRT). The median dose of plan target volume(PTV) and gross target volume(GTV) were both 60 Gy. The median follow-up time was 59.2 months. Log rank test and Cox regression analysis were used for univariat and multivariate analysis, respectively. Results: The percentage of normal lung receiving at least 20 Gy (V(20)) was (18.65±7.20)%, with average dose of (10.81±42.05) Gy. The percentage of normal heart receiving at least 30 Gy (V(30)) was (14.21±12.28)%. The maximum dose of exposure in spinal cord was (39.65±8.13) Gy. The incidence of radiation pneumonia and radiation esophagitis were 14.80%(29/196) and 65.82%(129/196), respectively. The adverse events were mostly grade 1-2, without grade 4 toxicity. Median overall survival (OS) and progression-free survival (PFS) were 70.1 months and 62.3 months, respectively. The 1-, 3- and 5-year OS rates of all patients were 75.1%、57.4% and 53.2%, respectively. The 1-, 3- and 5-year PFS rates were 75.1%、57.4% and 53.2%, respectively. Multivariate analysis demonstrated that patients'age (HR=1.023, P=0.038) and tumor diameter (HR=1.243, P=0.028)were the independent prognostic factors for OS, while tumor volume were the independent prognostic factor for PFS. Conclusions: Definitive radiotherapy is a promising therapeutic method in patients with T1-2N0M0 ESCC. Patients' age, tumor diameter and tumor volume may impact patients' prognosis.

Impaired bone microarchitecture in distal interphalangeal joints in patients with primary hypertrophic osteoarthropathy assessed by high-resolution peripheral quantitative computed tomography.

This study aimed to investigate the bone impairment in finger joints in PHO patients by HR-pQCT. Results showed distinguished differences in bone architecture and biomechanics parameters at DIPs between PHO patients and healthy controls using HR-pQCT assessment. Besides, serum PGE2, hsCRP and ESR levels were found negatively correlated with total vBMD. INTRODUCTION: This study aimed to investigate the bone impairment in finger joints in primary hypertrophic osteoarthropathy (PHO) patients firstly by high-resolution peripheral quantitative computed tomography (HR-pQCT). METHODS: Fifteen PHO patients and 15 healthy controls were enrolled in this study. Bone erosions in hands at distal interphalangeal joints (DIPs) in both PHO patients and controls were evaluated by X-ray. Bone geometry, vBMD, microstructure parameters, and size of individual bone erosion were also measured at the 3rd DIP by HR-pQCT as well. Blood biochemistry levels between the two groups were also compared. RESULTS: Compared to X-ray, HR-pQCT assessment were more sensitive for detection of bone erosions, with 14 PHO patients by HR-pQCT versus ten PHO patients by X-ray judged at the 3rd DIP. The average depth, width, and volume of erosions size in PHO patients were 1.38 ± 0.80 mm, 0.79 ± 0.27 mm, and 1.71 ± 0.52 mm3, respectively. The bone cross-areas including total area (+ 25.3%, p ≤ 0.05), trabecular area (+ 56.2%, p ≤ 0.05), and cortical perimeter (+ 10.7%, p ≤ 0.05) at the defined region of interest of 3rd DIP was significantly larger than controls. Total vBMD was 11.9% lower in PHO patients compared with the controls (p ≤ 0.05). Biochemical test results showed the increased levels of inflammatory cytokines, bone resorption markers, and joint degeneration markers in PHO patients. Serum prostaglandin PGE2, high-sensitive C-reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR) levels were found negatively correlated with total vBMD. CONCLUSIONS: This study demonstrated higher sensitivity of the HR-pQCT measurement at DIPs by showing the differences in architecture and biomechanics parameters at DIPs between the PHO patients and healthy controls, which would be of interest clinically to investigate bone deterioration in PHO patients.

Long noncoding RNA LUCAT1 promotes cervical cancer cell proliferation and invasion by upregulating MTA1.

OBJECTIVE: Recent researches have revealed the role of long noncoding RNAs (lncRNAs) in the development of tumors. In this study, lncRNA LUCAT1 was explored to identify how it affected the progression of cervical cancer. PATIENTS AND METHODS: Quantitative Real-time polymerase chain reaction (qRT-PCR) was used to detect LUCAT1 expression in both cervical cancer cells and tissue samples. Moreover, the associations between LUCAT1 expression level and patients' overall survival rate were explored, respectively. In addition, cell proliferation assay and transwell assay were conducted. Furthermore, the underlying mechanism was explored via performing qRT-PCR and Western blot assay. RESULTS: By comparing with the expression level in corresponding ones, the LUCAT1 expression level in cervical cancer samples was significantly higher. Moreover, expression level of LUCAT1 was negatively correlated with patients' overall survival time. In addition, after LUCAT1 was overexpressed, cell proliferation, cell invasion and migration capacities were promoted in vitro. In addition, the mRNA and protein expressions of MTA1 were upregulated after LUCAT1 was overexpressed. Furthermore, it was found that the expression level of MTA1 was positively related to LUCAT1 expression level in cervical cancer tissues. CONCLUSIONS: We showed that LUCAT1 could enhance proliferation, invasion and migration of cervical cancer cells through upregulating MTA1, which might offer a potential therapeutic choice for patients with cervical cancer.

Impact of the Mechanical Properties of a Functionalized Cross-Linked Binder on the Longevity of Li-S Batteries.

One of the very challenging aspects of Li-S battery development is the fabrication of a sulfur electrode with high areal loading using conventional Li-ion binders. Herein, we report a new multifunctional polymeric binder, synthesized by the free-radical cross-linking polymerization of [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETMAC) and ethylene glycol diacrylate (EGDA) to form poly(AETMAC- co-EGDA), that not only helps to confine the soluble polysulfide species but also has the desired mechanical properties to allow stable cycling of high-sulfur loading cathodes. Through a combination of spectroscopic and electrochemical studies, we elucidate the chemical interactions that inhibit polysulfide shuttling. We also show that extensive cross-linkage enables this polymeric binder to exhibit a low degree of swelling as well as high tensile modulus and toughness. These attributes are essential to maintain the architectural integrity of the sulfur cathode during extended cycling. Using this material, Li-S cells with a high-sulfur loading (6.0 mg cm-2) and a low-intermediate electrolyte/sulfur ratio (7 µL:1 mg) achieve an areal capacity of 5.4 mA h cm-2 and can be (dis)charged for 300 cycles with stable reversible redox behavior after the initial cycles.

Novel SLCO2A1compound heterozygous mutation causing primary hypertrophic osteoarthropathy with Bartter-like hypokalemia in a Chinese family.

PURPOSE: Primary hypertrophic osteoarthropathy (PHO) is an inherited disease characterized by digital clubbing, periostosis and pachydermia with defects in the degradation of prostaglandin E2 (PGE2). Mutations in SLCO2A1 gene-encoding prostaglandin transporter (PGT) resulted in PHO, autosomal recessive 2 (PHOAR2). The spectrum of mutations and variable clinical complications of PHOAR2 has been delineated. In this study, we investigated a Chinese PHO family with a manifestation of Bartter-like hypokalemia. METHODS: Clinical manifestations were collected and genetic analyses were performed in the PHO family. RESULTS: The 33-year-old male proband had severe hypokalemia due to potassium loss from the kidney, while his brother had mild hypokalemia. After being treated with etoricoxib, the serum potassium level of the patient increased rapidly to the normal range which corresponded with the reduction in his serum PGE2 and PE2 metabolite (PGEM) levels. A novel SLCO2A1 compound heterozygous mutation of p.I284V and p.C459R was identified in two PHO patients in this family. CONCLUSIONS: The present findings supported that the Bartter-like hypokalemia is a new complication of PHOAR2 caused by the high level of PGE2. Etoricoxib was demonstrated to be effective for the renal hypokalemia in PHO patients.

Inflammation-based prognostic scores in patients with extrahepatic bile duct lesions treated by percutaneous transhepatic biliary stenting combined with 125I seeds intracavitary irradiation.

PURPOSE: This study aimed at investigating the efficacy of percutaneous transhepatic biliary stenting (PTBS) combined with 125I seeds intracavitary irradiation in the treatment of extrahepatic cholangiocarcinoma (EHC) and to preliminarily explore the prognostic values of inflammation-based scores in these patients. METHODS: A total of 113 clinically/pathologically diagnosed cases of EHC who received PTBS combined with 125I seeds implantation were retrospectively analyzed. The postoperative changes of clinical symptoms and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total serum bilirubin (TBIL), direct bilirubin (DBIL), and albumin (ALB) were observed. Preoperative clinical data were extracted to calculate inflammation-based scores, including systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelets-to-lymphocyte ratio (PLR). Kaplan-Meier survival curves and Cox regression analyses were used to evaluate the prognostic significance of inflammation-based scores. RESULTS: After operation, clinical symptoms such as jaundice and fever significantly improved in all patients. At 1 month and 3 months postoperatively, serum levels of ALT, AST, ALP, TBIL, and DBIL significantly reduced, and ALB significantly increased, compared with preoperative values. The median survival time of the patients was 12 months and the 1-year survival rate was 56.8%. Univariate analysis revealed that factors related to overall survival were CA19-9, TBIL, ALB, SII, and NLR. Multivariate analysis further identified SII and NLR as independent prognostic models. CONCLUSION: The combination of PTBS and 125I seeds intracavitary irradiation is an effective palliative treatment for advanced EHC. Elevated SII and NLR can be used to predict poor survival.
