RESUMO
OBJECTIVE: To explore the effect of individualized nutritional interventions on head and neck cancer (HNC) patients receiving radiotherapy and provide a basis for improving the quality of life for those patients. METHODS: A convenience sampling method was adopted to select HNC patients as the study objects. The Nutritional Risk Screening 2002 scale (NRS2002) was used to screen the nutritional risk in 108 HNC patients receiving radiotherapy, and the patients were randomly divided into control group and observation group. Routine dietary guidance was conducted in the control group, and individualized nutritional intervention was applied in the observation group. RESULTS: Six months after the intervention, the albumin levels (37.40 ± 4.03 g/L), hemoglobin levels (128.70 ± 15.22 g/L), and body mass index scores (BMI) (23.96 ± 3.23 kg/m2) of the observation group were all better than to those of control group (t = 2.370, 2.216, and 3.135, respectively, and P < 0.05 in all). Six months after the intervention, the anxiety and depression scores in observation group (27.6 ± 7.2 points, 27.3 ± 2.2 points) were lower than those in control group (38.6 ± 9.6 points, 37.9 ± 3.3 points). The quality-of-life score in the observation group was higher than that in control group. The nursing satisfaction in the observation group (96.43%) was higher than that in the control group (75.00%). CONCLUSION: The implementation of individualized nutritional intervention has promoted the improvement of laboratory indicators, weight, and BMI of head and neck cancer patients, reduced the risk of malnutrition of head and neck cancer patients, improved their quality of life, reduced the occurrence of adverse reactions during radiotherapy, and promoted long-term efficacy.

Currently, the treatment of cancer pain in China mainly follows the three-step pain relief principles formulated by the World Health Organization. As research on subarachnoid drug diffusion has intensified, intrathecal drug delivery has been gradually applied in the treatment of diseases, and improved analgesia can be achieved via the continuous infusion of small doses of morphine-derived drugs. This method can not only effectively relieve pain and enhance quality of life but also significantly reduce the incidence of nausea, vomiting, constipation, and other adverse reactions caused by the long-term intensive use of drugs in patients with cancer pain. This study summarizes the development of the intrathecal drug-infusion system for treating cancer pain in patients with advanced cancer and describes the drugs used, the advantages in pain treatment, and key nursing factors before and after device placement to provide a basis for alleviating pain in patients with cancer.

METHODS: 36 female BALB/c mice were selected and randomly divided the mice into four groups. We established a BALB/c mouse model of TCE sensitization and pretreatment with GdCl3 (40 mg/kg) by intraperitoneal injection during the during the 17th and 19th days. RESULTS: We found F4/80, the marker of Kupffer cell, was increased in TCE positive group. GdCl3 treatment successfully blocked the activation of Kupffer cell. TNF-α was increased significantly in liver of TCE sensitized mice and decreased significantly when low-dose GdCl3 was used. We found TNF receptor 1 (TNFR1) was increased significantly and GdCl3 treatment resumed the expression of TNFR1 to normal level, as well as the F4/80, TNF-α and TNFR1 mRNA. We also found both caspase-8 and caspase-3 increased in TCE positive group and decreased in TCE + GdCl3 positive group. The number of apoptotic cells in TCE sensitized mice increased by TUNEL staining, and GdCl3 treatment alleviated this increase. Some cells showed edema and inflammatory cell aggregation in liver of TCE positive group, while in the TCE + GdCl3 positive group, the cytoplasm became loose and vacuole-like degeneration occurred. CONCLUSION: Our study unveils cross-talk between Kupffer cell activation and TNFR1 which mediate apoptosis in liver of TCE sensitized mice.

BACKGROUND: Colorectal polyps are frequently observed in patients with type 2 diabetes mellitus (DM), posing a significant risk for colorectal cancer. Metformin, a widely prescribed biguanidine drug for type 2 DM, has been suggested to have potential chemoprophylactic effects against various cancers. AIM: To explore the correlation between colorectal polyps and metformin use in type 2 DM patients. METHODS: Type 2 DM patients were categorized into polyp and non-polyp groups. Following this, all patients were categorized into the type 2 DM-metformin, type 2 DM-non-metformin, and non-type 2 DM groups. Based on the baseline colonoscopy results, we performed pairwise comparisons of the incidence of colorectal polyps among the three groups. Additionally, we analyzed the relationship between colorectal polyps and the duration of metformin use and between the size and number of polyps and metformin use. Simultaneously, we focused on the specific pathological types of polyps and analyzed their relationship with metformin use. Finally, we compared the incidence of polyps between metformin and non-metformin groups according to the interval colonoscopy results. RESULTS: The rate of metformin use in patients with colorectal polyps was 0.502 times that of patients without colorectal polyps [odds ratio (OR) = 0.502, 95% confidence interval (CI): 0.365-0.689; P < 0.001]. The incidence of colorectal polyps did not differ significantly between the type 2 DM-metformin and non-type 2 DM groups (P > 0.05). Furthermore, the correlations between the duration of metformin use and the incidence of colorectal polyps and between the size and number of polyps and metformin use were not statistically significant (P > 0.05). Metformin use did not affect the incidence of colorectal polyps during interval colonoscopy (P > 0.05). CONCLUSION: Metformin use and colorectal polyp incidence in type 2 DM patients showed a negative correlation, independent of the hypoglycemic effect of metformin.
RESUMO
OBJECTIVE: In this study, we investigated the prevalence of malnutrition and analyzed the related factors among patients with head and neck cancer (HNC) undergoing radiotherapy. METHODS: We included 108 patients with head and neck cancer undergoing radiotherapy from the oncology and thoracic surgery departments of a comprehensive medical center in Qingdao between January 2019 and June 2020. We used the Nutritional Risk Screening-2002 tool (NRS-2002) to evaluate their nutritional status during radiotherapy. We analyzed the basic sociodemographic information and laboratory indicators of the respondents to examine the impact of these factors on nutritional status. RESULTS: In the 108 patients that we studied, those aged ≥65 years had a significantly higher nutritional risk when compared to patients <65 years of age (P < 0.05). Univariate analysis revealed that a late tumor stage (P = 0.039), the neck being the site of radiotherapy (P = 0.009), the presence of diabetes (P < 0.001), and the presence of anxiety and depression (P = 0.002) were associated with nutritional risks for patients with head and neck cancer undergoing radiotherapy. Multivariate logistic regression analysis identified a late tumor stage, the neck being the radiotherapy site, and combined anxiety and depression as nutritional risk factors in such patients. CONCLUSION: We found a high incidence of malnutrition in patients undergoing radiotherapy for HNC; this highlights the importance of early identification of patients at risk and evaluation of related risk factors to enhance the efficacy of nutritional interventions.
RESUMO
BACKGROUND: The nursing model of establishing a chemotherapy safety management supervisory group has guaranteed the safety and effectiveness of intravenous chemotherapy while reducing the adverse effects of chemotherapy and improving patient satisfaction and quality of life. OBJECTIVE: To explore the impact of establishing a nursing supervision group on improving the safety management of patients receiving chemotherapy in the oncology department. METHODS: We selected a total of 60 patients who underwent chemotherapy at the oncology department between January and June 2021 and assigned them to the control group. They received conventional chemotherapy safety management nursing care. We selected another 60 patients undergoing chemotherapy in the oncology department between July and December 2021 and assigned them to the observation group. They received a nursing intervention model facilitated by the chemotherapy safety supervision team. We compared the intervention effects in the two groups. RESULTS: Patient satisfaction was significantly higher in the observation group than in the control group (P< 0.05); the incidence of post-chemotherapy nausea and vomiting was significantly lower in the observation group than in the control group (P< 0.05); and the self-rating depression scale (SDS) and self-rating anxiety scale (SAS) scores of patients in the observation group were reduced (P< 0.05) and significantly lower than in the control group (P< 0.05). We used the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-core 30 (EORTC-QLQ-C30) and found a statistically significant difference in the quality of life of patients before the nursing intervention and on the day of discharge (P< 0.05). CONCLUSION: The establishment of a chemotherapy safety management supervisory group was effective in reducing the incidence of post-chemotherapy nausea and vomiting as well as the patient's psychological burden; it could also improve the quality of life of patients and their satisfaction with nursing care.
RESUMO
OBJECTIVE: To study the better efficacy of clinic treatment for dermatitis medicamentosa like of trichloroethylene (DMLT) and observe the clinic efficacy of Xuebejing injection for DMLT patients with systemic inflammatory response syndrome (SIRS). METHODS: 16 DMLT patients with SIRS were randomly divided into control group (conventional therapy) and xuebijing group (conventional therapy plus xuebijing). We evaluated all the patients with APACHE II before treatment and checked the TNF-alpha in blood at the different time (before treatment and the 7th day of treatment). The total usages, first dosage of medrol and the time of therapy for each group were counted. RESULTS: All patients were cured, there was no significant difference according to APACHE II and TNF-alpha before treatment in two groups . The level of TNF-alpha of all the patients were decreased markedly, but more significantly in xuebijing group (P < 0.01). Moreover, the treatment group patients were given relatively less total usages, first dosage of medrol and time of therapy (P < 0.01). CONCLUSION: Xuebejing injection combined glucocorticoids can cure DMLT patients with SIRS effectively, and reduce the total usages, first dosage of medrol and time of therapy.

OBJECTIVE: To investigate the efficacy and safety of ultrasound-guided selective nerve branch blockage in the treatment of lumbar spinal nerve posterior branch syndrome. METHODS: A total of 40 patients with lumbar spinal nerve posterior branch syndrome treated by Pain Clinic from May 2017 to December 2018 were selected. According to the method used in locating site for nerve blockage, the patients were divided into ultrasound-guided group and anatomical positioning group, with 20 cases in each group. In anatomical positioning group, there were 7 males and 13 females, aged (63.42±7.71) years old, weighted (63.65±10.72) kg, numerical rating scale (NRS) was (6.61±1.52) scores, course of disease was (16.55±4.68) months. Pain sites:4 cases at L2,3, 8 cases at L3,4, 11 cases at L4,5, and 11 cases at L5S1. In ultrasound-guided group, there were 10 males and 10 females, aged (59.58±10.21) years old, weighted (60.61±13.81) kg, NRS was(6.84±2.43) scores, and course of disease was(13.70±5.98) months. Pain sites:6 cases at L2,3, 6 cases at L3,4, 9 cases at L4,5, and 13 cases at L5S1. Ultrasound-guided group used ultrasound-guided selective posteromedial branch and posterolateral branch nerve blockage, and the anatomical positioning group used anatomical localization method to block the posteromedial branch and posterolateral branch of lumbar spinal nerve. Each nerve branch was injected 3 ml of 0.125% ropivacaine. The number of treatment required and prone position time of each treatment were recorded, and the NRS scores of patients at the time points of immediately after the end of the treatment, the first week, the second week, the first month and the third month were evaluated. And adverse events such as local anesthetic allergy and poisoning, local puncture infection, total spinal anesthesia, dizziness, drowsiness, nausea, vomiting and other adverse reactions were observed. RESULTS: There were no statistically significant differences in gender, age, weight, NRS, course of disease and pain segment distribution between two groups (P>0.05). The number of treatment required in anatomical positioning group was significantly higher than that in ultrasound-guided group (P<0.000 1). During each treatment, the time in the prone position of the patients in anatomical positioning group was significantly lower than that in ultrasound guided group (P< 0.000 1). NRS scores immediately after the end of treatment, 1 week, 2 weeks, 1 month and 3 months, anatomical positioning group were 2.98 ±0.25, 3.04 ±0.38, 3.37 ±0.47, 3.42 ±0.85, 3.50 ±0.43, respectively, 2.94 ±0.31, 3.00 ±0.29, 3.21 ±0.68, 3.16 ± 0.94, 3.17±0.53 in ultrasound-guided group, and there was significant difference at 1 month and 3 months between two groups(P< 0.05). There were no adverse events such as local anesthetic allergy and poisoning, local puncture infection, and total spinal anesthesia, and no adverse reactions such as lethargy, nausea, and vomiting occurred in two groups. There were 6 cases of dizziness in anatomical positioning group and 12 cases in ultrasound guided group. The difference between two groups was statistically significant(P<0.05). CONCLUSION: Comparedwith anatomicalpositioning, ultrasound-guided selective nerve branch block for the treatment of posterior branch of the lumbar spinal cord syndrome can reduce the number of treatments and maintain a longer therapeutic effect, but it is also necessary to pay attention to the time of each treatment to avoid dizziness and other adverse reactions.

OBJECTIVE: PEGylated superparamagnetic iron oxide (SPIO) is the most promising alternatives to gadolinium-based contrast agents (GBCAs) in MRI. This paper is to explore the imaging effects of PEGylated SPIO, which is influenced by particle sizes and surface polyethylene glycol (PEG) coating, using as MRI contrast agents at different magnetic field intensities. METHODS: Firstly, nine PEGylated monocrystalline SPIO nanoparticles with different nanocrystal sizes and different molecular weights PEG coating were prepared, and then physical and biological properties were analyzed. Finally, MRI imaging in vivo was performed to observe the imaging performance. RESULTS: Nine PEGylated monocrystalline SPIO nanoparticles have good relaxivities, serum stability, and biosecurity. At the same time, they show different imaging characteristics at different magnetic field intensities. Eight-nanometer SPIO@PEG5k is an effective T 2 contrast agent at 3.0 T (r 2/r 1 = 14.0), is an ideal T 1-T 2 dual-mode contrast agent at 1.5 T (r 2/r 1 = 6.52), and is also an effective T 1 contrast agent at 0.5 T (r 2/r 1 = 2.49), while 4-nm SPIO@PEG5k is a T 1-T 2 dual-mode contrast agent at 3.0 T (r 2/r 1 = 5.24), and is a useful T 1 contrast agent at 0.5 T (r 2/r 1 = 1.74) and 1.5 T (r 2/r 1 = 2.85). MRI studies in vivo at 3.0 T further confirm that 4-nm SPIO@PEG5k displays excellent T 1-T 2 dual-mode contrast enhancement, whereas 8-nm SPIO@PEG5k only displays T 2 contrast enhancement. CONCLUSION: PEGylated SPIOs with different nanocrystal sizes and PEG coating can be used as T 1, T 2, or T 1-T 2 dual-mode contrast agents to meet the clinical demands of MRI at specific magnetic fields.

BACKGROUND: To evaluate the role of high-resolution computed tomography (HRCT) in the diagnosis of 2019 novel coronavirus (2019-nCoV) pneumonia and to provide experience in the early detection and diagnosis of 2019-nCoV pneumonia. METHODS: Seventy-two patients confirmed to be infected with 2019-nCoV from multiple medical centers in western China were retrospectively analyzed, including epidemiologic characteristics, clinical manifestations, laboratory findings and HRCT chest features. RESULTS: All patients had lung parenchymal abnormalities on HRCT scans, which were mostly multifocal in both lungs and asymmetric in all patients, and were mostly in the peripheral or subpleural lung regions in 52 patients (72.22%), in the central lung regions in 16 patients (22.22%), and in both lungs with "white lung" manifestations in 4 patients (5.56%). Subpleural multifocal consolidation was a predominant abnormality in 38 patients (52.78%). Ground-glass opacity was seen in 34 patients (47.22%). Interlobular septal thickening was found in 18 patients, 8 of whom had only generally mild thickening with no zonal predominance. Reticulation was seen in 8 patients (11.11%), and was mild and randomly distributed. In addition, both lungs of 28 patients had 2 or 3 CT imaging features. Out of these 72 patients, 36 were diagnosed as early stage, 32 patients as progressive stage, and 4 patient as severe stage pneumonia. Moreover, the diagnostic accuracy of HRCT features combined with epidemiological history was not significantly different from the detection of viral nucleic acid (all P >0.05). CONCLUSIONS: The HRCT features of 2019-nCoV pneumonia are characteristic to a certain degree, which when combined with epidemiological history yield high clinical value in the early detection and diagnosis of 2019-nCoV pneumonia.

AIM: To evaluate immunological protection of nitric oxide (NO) in hepatopulmonary syndrome and probable mechanisms of ischemia-reperfusion (IR) injury in rat liver transplantation. METHODS: Sixty-six healthy male Wistar rats were randomly divided into three groups (11 donor/recipient pairs). In group II, organ preservation solution was lactated Ringer's solution with heparin 10,â 000/µL at 4â °C. In groupsâ Iâ and III, the preservation solution added, respectively, L-arginine or N(G)-L-arginine methyl ester (L-NAME) (1 mmol/L) based on group II, and recipients were injected with L-arginine or L-NAME (50 mg/kg) in the anhepatic phase. Grafted livers in each group were stored for 6 h and implanted into recipients. Five rats were used for observation of postoperative survival in each group. The other six rats in each group were used to obtain tissue samples, and executed at 3 h and 24 h after transplantation. The levels of alanine aminotransferase (ALT), tumor necrosis factor (TNF)-α and NO metabolites (NOx) were detected, and expression of NO synthase, TNF-α and intercellular adhesion molecule 1 (ICAM-1) was examined by triphosphopyridine nucleotide diaphorase histochemical and immunohistochemical staining. RESULTS: By supplementing L-arginine to strengthen the NO pathway, a high survival rate was achieved and hepatic function was improved. One-week survival rate of grafted liver recipients in groupâ Iâ was significantly increased (28.8 ± 36.6 d vs 4 ± 1.7 d, P < 0.01) as compared with groups II and III. Serum levels of ALT in groupâ Iâ were 2-7 times less than those in groups II and III (P < 0.01). The cyclic guanosine monophosphate (cGMP) levels in liver tissue and NOx in groupâ Iâ were 3-4 times higher than those of group II after 3 h and 24 h reperfusion, while in group III, they were significantly reduced as compared with those in group II (P < 0.01). The levels of TNF-α in groupâ Iâ were significantly lower than in group II after 3 h and 24 h reperfusion (P < 0.01), while being significantly higher in group III than group II (P < 0.01). Histopathology revealed more severe tissue damage in graft liver and lung tissues, and a more severe inflammatory response of the recipient after using NO synthase inhibitor, while the pathological damage to grafted liver and the recipient's lung tissues was significantly reduced in groupâ Iâ after 3 h and 24 h reperfusion. A small amount of constitutive NO synthase (cNOS) was expressed in liver endothelial cells after 6 h cold storage, but there was no expression of inducible NO synthase (iNOS). Expression of cNOS was particularly significant in vascular endothelial cells and liver cells at 3 h and 24 h after reperfusion in group II, but expression of iNOS and ICAM-1 was low in groupâ I. There was diffuse strong expression of ICAM-1 and TNF-α in group III at 3 h after reperfusion. CONCLUSION: The NO/cGMP pathway may be critical in successful organ transplantation, especially in treating hepatopulmonary syndrome during cold IR injury in rat orthotopic liver transplantation.

OBJECTIVE: To probe into the clinical effect of needle-pricking therapy for treatment of polycystic ovarial syndrome. METHODS: One hondred and twenty-one cases of polycystic ovarial syndrome were divided into a needle-pricking therapy group of 61 cases and a medication group of 60 cases with randomized and controlled method. The needle-pricking therapy group were treated by needle-pricking therapy at sacral plexus stimulating points on both sides of the spine and lateral points of Dazhui (CV 14), and the medication group by oral administration of domiphen and intramuscular injection of chorionic gonadotropin (HCG). Levels of hormones and symptoms in the patients before treatment, after treatment of 3 cycles and at the sixth cycle after treatment were investigated. RESULTS: After treatment of 3 cycles, the level of hormone and B type ultrasound examination were significantly improved in the two groups (P < 0.01). At the sixth cycle after treatment, the conditions of the patients in the medication group were returned to the original levels before treatment, while the conditions in the needle-pricking therapy group still kept at the post-therapeutic level, and their menstruation and ovulation restored to normal state, and the ovulation mucosa and the pregnancy rate were significantly higher than those in the medication group (all P < 0.01). CONCLUSION: Needle-pricking therapy has obvious effect on polycystic ovarial syndrome, and has a good long-term therapeutic effect.
