ABSTRACT

Objective To understand the prevalence of family cancer history among lung cancer patients. Methods The family cancer history of 418 patients with lung cancer was investigated by a face-to-face survey in Bazhong area according to the " Questionnaire on Family History and Medical History of Population Diseases". Results The positive rates of family history of cancer and lung cancer in the 418 patients with lung cancer were 36.12% (151/418) and 28.47% (119/418), respectively. There was no statistical difference in the positive rates between the two (P>0.05). Among the patients' family members, the number of cancer-positive people was mainly 3 or less. The higher the number, the lower the probability (P<0.05). The positive rates of family history of cancer and lung cancer in first-degree relatives were significantly higher than those of second-degree and third-degree relatives (P<0.05). Conclusion Targeted health education for cancer patients and their families, especially health education for first-degree relatives, may help improve the early diagnosis of lung cancer patients.

ABSTRACT

Objective:To evaluate the effects of intermittent change the angle of operating table on the skin in pressure areas of patients in prone position.Methods:A total of 150 hospitalized patients for elective surgical treatment in Yantai Yuhuangding Hospital from January 2019 to June 2019 were selected as subjects. The patients were divided into control group, 15° test group and 30° test group by random number table method, with 50 patients in each group. The control group received routine intraoperative pressure ulcer prevention measures, the 15° test group on the control group, the itinerant nurses adjusted the angle of the operating table according to the left 15°-supine-right 15° every half hour, and the 30° test group on the control group, the itinerant nurses adjusted the angle of the operating table according to the left 30°-supine-right 30° every half hour. The incidence of surgically related pressure ulcers and doctors' satisfaction with the surgical position of the three groups of patients were evaluated.Results:Pressure ulcers occurred in 8 patients of the control group, the incidence of pressure ulcers was 16%. Pressure ulcer occurred in 0 patient of the 15° test group, the incidence of pressure ulcers was 0. Pressure ulcers occurred in 2 cases in the 30° test group, the incidence of pressure ulcers was 4%. The difference was statistically significant ( χ2 value was 10.120, P<0.05). Further comparison showed that the incidence of pressure ulcers was statistically significant between the control group and the 15° test group ( P<0.016 7), while the incidence of pressure ulcers was not statistically significant between the control group and the 30° test group, between the 15° test group and the 30° test group ( P>0.016 7). The results of the postoperative doctors' satisfaction with the surgical body position were (27.880 ± 1.637), (27.520 ± 1.693), (26.920 ± 1.947) points in the control group, the 15° test group and the 30° test group, there was a statistically significant difference among the three groups ( F value was 3.779, P<0.05). Further comparison showed that there was no statistically significant difference in the score of surgical position satisfaction between the control group and the 15° test group, between the 15° test group and the 30° test group ( P>0.05). The satisfaction score of surgeons in the control group was higher than that in the 30° test group, and the difference was statistically significant( P<0.05). Conclusions:Intermittent adjustment of surgical position can reduce the incidence of pressure ulcers and improve the quality of nursing in the operating room without affecting the convenience of the surgeon. The optimal effect was achieved by adjusting the angle of the operating bed according to the left-leaning 15°-supine-right-leaning 15°at an interval of 30 minutes.

ABSTRACT

To investigate the effects of different habitat processing methods of Salviae Miltiorrhizae Radix et Rhizoma on acute myocardial ischemia induced by pituitrin in rats. In this experiment, the tail vein injection of pituitrin was used to induce acute myocardial ischemia in rats. Electrocardiograph(ECG) heart rate and ΔST changes were recorded, and the levels of creatine kinase isoenzyme(CK-MB), lactate dehydrogenase(LDH), superoxide dismutase(SOD) and malondialdehyde(MDA) in serum of rats were detected to comprehensively evaluate the effects of six processing methods of Salviae Miltiorrhizae Radix et Rhizoma on serum biochemical indexes of rats with acute myocardial injury. The ECG results showed that the Salviae Miltiorrhizae Radix et Rhizoma dried in a drying oven had a good effect on the improvement of heart rate and ΔST of electrocardiogram after ischemia, and all the other groups had some protective effects to different degrees. The results of biochemical indexes in serum of each group after ischemia showed that the activity of CK-MB decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in a drying oven after sweating and losing weight in a drying oven, high-dose group with drying in the shade and low-dose group with drying in the shade. The activity of LDH decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in the shade and low-dose group of drying in the shade. The activity of SOD increased most significantly in Salviae Miltiorrhizae Radix et Rhizoma low-dose group with drying in sun, low-dose group with drying in sun after sweating and losing weight in sun, and low-dose group with drying in a drying oven. The activity of MDA decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma low-dose group with drying in sun. The comprehensive scoring results showed that the highest score was obtained in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in the shade while the scores of other treatment groups were higher than that of the model group. It could be seen that the Salviae Miltiorrhizae Radix et Rhizoma dried in a drying oven had a good improvement effect on electrocardiograph indexes after acute myocardial injury, the Salviae Miltiorrhizae Radix et Rhizoma dried in the shade had a good improvement effect on serum myocardial enzymes after acute myocardial injury, and the other processing methods had a certain protective effect on myocardial injury. The six processing methods evaluated by pharmacodynamics showed that the Salviae Miltiorrhizae Radix et Rhizoma dried in the shade and dried in a drying oven had good efficacy.

ABSTRACT

The data of patients of both sexes, aged ≥ 18 yr, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, underwent thoracoscopic lung surgery under general anesthesia from January 2017 to December 2017, were retrospectively collected.The patients were divided into 2 groups according to whether they received thoracic paravertebral block (PVB) before operation: general anesthesia group (group G) and thoracic PVB combined with general anesthesia group (GP group). T 3/T 4 and T 6/T 7 double point thoracic PVB was performed under ultrasound guidance before anesthesia induction in GP group.Anesthesia was induced with sufentanil, propofol/etomidate and cisatracurium and maintained with propofol, remifentanil, cisatracurium and dexmedetomidine during operation.According to whether sufentanil was added before skin incision, patients received thoracic PVB combined with general anesthesia were divided into 2 subgroups: increment of sufentanil group and non-increment of sufentanil group, and a 1∶1 propensity score matching was performed in two groups.The usage of vasopressor drugs, amount of opioids consumed, volume of fluid infused, urine volume, blood loss and operation time were recorded.Compared with group G, the intraoperative urine volume, volume of fluid infused, and requirement for vasopressor drugs after skin incision were increased, and the intraoperative consumption of remifentanil was reduced in group GP ( P<0.05). Before matching, compared with non-increment of sufentanil group, the consumption of sufentanil at induction, intraoperative blood loss, volume of fluid infused and urine volume were significantly increased, and the operation time was prolonged in increment of sufentanil group ( P<0.05). After matching, compared with non-increment of sufentanil group, the requirement for vasopressor drugs was significantly increased in increment of sufentanil group ( P<0.05). In conclusion, thoracic PVB can increase the incidence of intraoperative hypotension in the patients undergoing thoracoscopic lung surgery under general anesthesia, and the reason may be related to the thoracic PVB-induced direct inhibition of sympathetic nerves and to opioids usage.

ABSTRACT

OBJECTIVE: To validate the 2016 ISGPS definition and grading scheme and investigate whether it segregates into distinct subclasses. METHODS: A total of 522 patients undergone pancreaticoduodenectomy in two pancreatic centers were reviewed. The 2016 ISGPS scheme was validated by comparing clinical and economic outcomes between different ISGPS grades. B-POPF were divided into 2 subgroups as B1(without invasive procedures) and B2(with invasive procedures) then outcomes were analyzed across the subgroups. RESULTS: Biochemical leak(BL) did not differ from the non-fistula condition in all outcomes except postoperative hospital stay and cost. Non-fistula/BL,B-POPF and C-POPF condition differed significantly in terms of all clinical and economic outcomes except 30-day readmission rate.B1 differ from B2 subgroup greatly in terms of most critical terms of outcomes such as hemorrhage(15.2% vs. 34.3%,P=0.045),biliary fistula(13.0% vs 34.3%,P=0.023),postoperative hospital stay(32.0 d vs. 39.0 d,P=0.011). CONCLUSION: The present study has confirmed the effectiveness of the 2016 ISGPS definition and grading scheme in identifying three conditions that differ in terms of clinical and economic outcomes. Subclassification of B-POPF according to whether invasive procedures has been used has potential implications for accurate reporting and performance evaluation.

ABSTRACT

Odontogenic keratocysts (OKCs) are common cystic lesions of odontogenic epithelial origin that can occur sporadically or in association with naevoid basal cell carcinoma syndrome (NBCCS). OKCs are locally aggressive, cause marked destruction of the jaw bones and have a propensity to recur. PTCH1 mutations (at ∼80%) are frequently detected in the epithelia of both NBCCS-related and sporadic OKCs, suggesting that PTCH1 inactivation might constitutively activate sonic hedgehog (SHH) signalling and play a major role in disease pathogenesis. Thus, small molecule inhibitors of SHH signalling might represent a new treatment strategy for OKCs. However, studies on the molecular mechanisms associated with OKCs have been hampered by limited epithelial cell yields during OKC explant culture. Here, we constructed an isogenic PTCH1 cellular model of PTCH1 inactivation by introducing a heterozygous mutation, namely, c.403C>T (p.R135X), which has been identified in OKC patients, into a human embryonic stem cell line using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system. This was followed by the induction of epithelial differentiation. Using this in vitro isogenic cellular model, we verified that the PTCH1 heterozygous mutation causes ligand-independent activation of SHH signalling due to PTCH1 haploinsufficiency. This activation was found to be downregulated in a dose-dependent manner by the SHH pathway inhibitor GDC-0449. In addition, through inhibition of activated SHH signalling, the enhanced proliferation observed in these induced cells was suppressed, suggesting that GDC-0449 might represent an effective inhibitor of the SHH pathway for use during OKC treatment.

ABSTRACT

To accurately discriminate Stellariae Radix from its adulterants, four leading candidate DNA barcoding markers were evaluated. Sixty samples including Stellariae Radix and its adulterants have been newly collected and their total genomic DNA was extracted. Four DNA barcoding markers ITS, rbcL, psbA-trnH and matK were amplified and sequenced. Their sequence characteristic analyses, Kimura-2-parameter (K2P) distance calculation and Neighbor-joining (NJ) phylogenetic tree constructions were accomplished using the MEGA 7.0 software. DNA Barcoding gaps of the four DNA barcoding markers were estimated by the distributions of inter- and intra-sequence specific variations. Species identification efficiency was calculated using the BLAST method. The results showed that ITS had the highest (95.2%) while matK demonstrated the lowest (75%) PCR and sequencing efficiency. The length range of the four markers were in the ranger of 211-797 bp, and the G+C content of ITS was highest (54.35%). The identification efficiency of matK and ITS was 92% and 90% respectively. Barcoding gap could be found in ITS sequences. The NJ phylogenetic tree constructed using ITS sequences showed that samples of Stellariae Radix were separately formed into one clade, and samples of adulterants like Stellaria bistyla were clearly belong to different branches from Stellariae Radix, whereas NJ trees constructed using psbA-trnH, rbcL and matK could not differentiate Stellariae Radix from its adulterants. Therefore, ITS regions as DNA barcodes can stably and accurately distinguished Stellariae Radix from its adulterants, and provide a new technique for modern identification of Stellariae Radix.

ABSTRACT

Background: Recombinant human adenovirus type 5 is an oncolytic adenovirus, which can selectively replicate in tumor cells and lyse the tumor cells resulting in dissolution and necrosis of tumor tissues. Aims: To evaluate the efficacy and safety of endoscopic injection of recombinant human adenovirus type 5 in the treatment of advanced esophageal cancer. Methods: A total of 87 patients with advanced esophageal cancer from January 2012 to October 2017 at Qingdao Municipal Hospital were enrolled. According to the treatment performed, patients were divided into recombinant human adenovirus type 5 group (group A), radiation and chemotherapy group (group B) and recombinant human adenovirus type 5 combined with radiation and chemotherapy group (group C). The clinical efficacy, survival rate and adverse reaction rate were compared among the three groups. Results: No significant differences in clinicopathological features were found among the three group (P>0.05). The effective rate, 1-year survival rate, 2-year survival rate, median overall survival, median progression-free survival in groups C were significantly higher than those in group A and group B (P0.05). Adverse reaction rate in group A was significantly decreased than that in group B and group C (P0.05). Conclusions: The therapeutic effect of endoscopic injection of recombinant human adenovirus type 5 combined with radiation and chemotherapy for treatment of advanced esophageal cancer is remarkable, and is an important novel way for the treatment of advanced esophageal cancer, which does not increase obviously the incidence of adverse reactions.

ABSTRACT

Objective@#To analyze the clinical and genotypic characteristics of infantile inflammatory bowel disease (IBD).@*Methods@#The age of onset, family history, clinical manifestations, and treatment effect were retrospectively analyzed in 39 infants (male 23 cases, female 16 cases) with IBD who were admitted to the Department of Gastroenterology in Children′s Hospital, Capital Institute of Pediatrics from January 2007 to December 2017. Next generation sequencing (NGS) based on target gene panel was used for gene analysis in 17 patients.@*Results@#The median age of onset was 0.5 (0.5, 1.0) month. The most common clinical symptoms included diarrhea (39, 100%), malnutrition (38, 97%), hematochezia (34, 87%), fever (25, 64%), and perianal diseases (24, 61%). Four children had associated family history. Among the 17 patients whose gene was analyzed, 10 were found to have the pathogenic gene variation, within whom 7 had interleukin-10 receptor α subunit (IL-10RA) mutation, 2 had CYBB heterozygous mutation, 1 had interleukin-10 receptor β subunit (IL-10RB) mutation. The therapeutic medicine included mesalazine, steroids, and thalidomide. Eighteen children (46%) reached clinical remission (10 cases) or partial remission (8 cases).@*Conclusions@#The incidence of single gene mutation in infants with IBD is high, with IL-10RA mutation as the most common. Refractory diarrhea and malnutrition may indicate infantile IBD.

ABSTRACT

@#The aim of this study was to prepare the nanoconjugates for targeted photodynamic therapy of brain cancer by using eight-arm polyethylene glycol(8PEG)as the carrier and cRGD as the targeting ligand, and to investigate the antitumor effect and its mechanism. UV-Vis spectra and confocal microscopy were used for characterization and cellular uptake behavior of nanoconjugates respectively. Alamar Blue assay and Calcein AM/PI staining were applied to investigate the cytotoxocity of nanoconjugates against tumor cells, and tumor spheroid growth curve was used to assess the tumor growth suppression effect. In addition, the generation of reactive oxygen species(ROS), apoptosis and spheroid permeability test was used to reveal the antitumor mechanism of nanoconjugates. The results showed that cRGD-8PEG-IR700 was taken up efficiently by integrin overexpressed U87MG cells, while almost no uptake was found in integrin free NIH/3T3 cells. Remarkable photokilling effect against U87MG cells was only shown in cRGD-8PEG-IR700 group due to the light-induced ROS generation and apoptosis, whereas growth suppression effect was also observed in U87MG spheroids treated with cRGD-8PEG-IR700 plus light owing to the superior penetration ability of targeted nanoconjugates. Hence, tumor-targeted PEG nanoconjugates may provide a promising drug delivery system for photodynamic therapy of cancers.

ABSTRACT

Catalpol, a major bioactive component from Rehmannia glutinosa, which has been used to treat diabetes. The present study was designed to elucidate the anti-diabetic effect and mechanism of action for catalpol in db/db mice. The db/db mice were randomly divided into six groups (10/group) according to their blood glucose levels: db/db control, metformin (positive control), and four dose levels of catalpol treatment (25, 50, 100, and 200 mg·kg), and 10 db/m mice were used as the normal control. All the groups were administered orally for 8 weeks. The levels of fasting blood glucose (FBG), random blood glucose (RBG), glucose tolerance, insulin tolerance, and glycated serum protein (GSP) and the globe gene expression in liver tissues were analyzed. Our results showed that catalpol treatment obviously reduced water intake and food intake in a dose-dependent manner. Catalpol treatment also remarkably reduce fasting blood glucose (FBG) and random blood glucose (RBG) in a dose-dependent manner. The RBG-lowering effect of catalpol was better than that of metformin. Furthermore, catalpol significantly improved glucose tolerance and insulin tolerance via increasing insulin sensitivity. Catalpol treatment significantly decreased GSP level. The comparisons of gene expression in liver tissues among normal control mice, db/db mice and catalpol treated mice (200 and 100 mg·kg) indicated that there were significant increases in the expressions of 287 genes, whichwere mainly involved in lipid metabolism, response to stress, energy metabolism, and cellular processes, and significant decreases in the expressions of 520 genes, which were mainly involved in cell growth, death, immune system, and response to stress. Four genes expressed differentially were linked to glucose metabolism or insulin signaling pathways, including Irs1 (insulin receptor substrate 1), Idh2 (isocitrate dehydrogenase 2 (NADP), mitochondrial), G6pd2 (glucose-6-phosphate dehydrogenase 2), and SOCS3 (suppressor of cytokine signaling 3). In conclusion, catalpol ecerted significant hypoglycemic effect and remarkable therapeutic effect in db/db mice via modulating various gene expressions.
