RESUMO
Objective:To investigate the analgesic effect of intravenous anesthesia induction combined with anterior quadratus lumborum block (AQLB)and related hemodynamic changes in patients undergoing laparoscopic retroperitoneal partial nephrectomy (RPN).Methods:A total of 116 patients undergoing elective laparoscopic partial nephrectomy for renal tumors in Jinhua Central Hospital from August 2021 to February 2022 were randomly divided into two groups with 58 cases in each group. Patients in control group received intravenous anesthesia , while those in study group received intravenous anesthesia induction with AQLB. The analgesic effect was evaluated at 1, 6, 12, 24, and 48 h after the operation. The hemodynamics were monitored at the time of entering the operating room (T 0), 3 min after induction of anesthesia (T 1), at the beginning of the operation (T 2), after the operation (T 3), and leaving the operating room (T 4). Microcirculation was assessed at 1, 6, 12, 24, and 48 h after operation. Cognitive function was assessed 30min before anesthesia, 6 h, 24 h, and 72 h after operation. Results:At 1, 6, 12, 24 and 48 h after operation, the visual analogue scale (VAS) of the resting (quiet state) pain in the study group were 3.2±1.2, 2.6±0.3,2.0±0.4, 1.5±0.4 and 0.8±0.2, which were significantly lower than those in control group (4.0±1.7, 3.4±0.7, 2.9±0.5, 1.7±0.5 and 1.2±0.3) ( t=2.93, P=0.004; t=8.00, P<0.001; t=10.07, P<0.001; t=2.38, P=0.019; t=8.45, P<0.001). There was no significant difference in heart rate and mean arterial pressure (MAP) at T 0 between two groups ; no significant difference in the heart rate at T 1, T 2, T 3 and T 4. There were significant differences in MAP levels at T 1, T 2, T 3 and T 4 between study group [(80.0±8.0)mmHg (1 mmHg=0.133 kPa), (84.4±8.4)mmHg, (80.4±5.7)mmHg, (86.4±4.7)mmHg and control group (77.1±7.5)mmHg, (88.0±8.6)mmHg, (83.0±7.7)mmHg, (92.2±6.2) mmHg; t=2.01, P=0.046; t=2.28, P=0.024; t=2.07, P=0.041; t=5.68, P<0.001]. At 6, 12, 24 and 48 h after operation, the morphological scores of tube loops in the study group were 1.0±0.2, 0.8±0.2, 0.7±0.1 and 0.7±0.1, which were lower than those in the control group (1.1 ±0.2, 0.9±0.2, 0.8±0.2 and 0.8±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=3.41, P=0.001; t=5.39 , P < 0.001). The blood flow status scores of the study group were 1.1±0.2, 0.9±0.2, 0.8±0.2 and 0.6±0.1, which were lower than those of the control group (1.2±0.2, 1.0±0.2, 0.9±0.2 and 0.7±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=2.69, P=0.008; t=5.39, P<0.001).

Conclusion:Intravenous anesthesia induction combined with anterior quadratus lumborum block has a good analgesic effect in patients undergoing RPN, with stable hemodynamics and microcirculation, and not affecting cognitive function of patients.
RESUMO
Objective To explore radiation protection cognition and mental health status of the staff in the second level and lower hospitals of a certain city. Methods Design a questionnaire on radiation protection knowledge and conduct a mental health test. The content of the questionnaire includes 26 questions in 2 dimensions, including general personal information and radiation protection knowledge. Among them, there are 20 questions about radiation protection knowledge. the self-rating symptom scale (SCL-90) is selected for the mental health test, with a total of 90 questions. Results The average score of the radiation protection knowledge question survey was (13.62 ± 2.21) points. The accuracy is less than 60% 102 people (16.04%); 60%~79% 430 people (67.61%); ≥ 80% 104 people (16.35%). SCL90 test indicates that 38.99% (248/636) of radiation workers is poor in mental health, the scores of each main factor are higher than the national norm. Among them, the somatization, obsessive-compulsive symptoms, interpersonal sensitivity and anxiety of radiation workers were relatively significant, with statistical differences (P < 0.05). Conclusion The overall cognition level of radiation protection staff in primary hospitals of a certain city is very low, therefore, training and supervision need to be strengthened. There are still some radiation workers whose mental health is not good, and active psychological intervention measures should be taken.
RESUMO
Objective:To analyze the differential gene expression of Shufeng Xuanfei Jiedu formula on whole expression profiles of the inflammation-related cytokines in mice infected with influenza virus by the gene chip technology.Methods:Male ICR mice were divided into normal group (N group), influenza virus pneumonia model group (M group), oseltamivir control group (C group) and Shufeng Xuanfei Jiedu formula high, medium and low dose groups (SH, SM, SL groups) according to the random number table method, with 10 mice in each group. A mouse model of influenza virus pneumonia was established by nasal drip of influenza virus strain FM1 (0.05 mL); in group N, 0.05 mL normal saline was used. In SH, SM and SL groups, Shufeng Xuanfei Jiedu formula was prescribed after 2 hours of intranasal infection (drug concentration approximately 3.8, 1.9 and 1.0 kg/L), 0.2 mL once a day for 4 days; in group C, the dosage of oseltamivir was 2.5 kg/L; in group N and group M, distilled water was given. On the 5th day, the whole lung of mice was harvested, and the total RNA of lung tissue was extracted and detected after hybridization with mice whole gene expression spectrum chip. Differential expressed genes of cytokines involved in inflammatory pathways were selected. The intensity expression ratio of the chip probe signal in each group vs. M group was calculated, and P < 0.05 and log2 ratio > 1 were defined as up-regulated genes, while P < 0.05 and log2 ratio < -1 were down-regulated genes. The mRNA expressions of interleukin (IL-1, IL-8) and intercellular adhesion molecule-1 (ICAM-1) were detected by reverse transcription-polymerase chain reaction (RT-PCR). Results:Compared with group N, the differential gene expressions of IL-1, IL-8 and ICAM-1 in group M were significantly up-regulated [log2 (N/M) were 2.62, 2.07, 1.41, respectively, all P < 0.05]. Compared with group M, the gene expressions of IL-1, IL-8, ICAM-1 were significantly down-regulated in SH, SM, SL and C groups [log2 (SH/M) were -1.91, -1.85, -0.88; log2 (SM/M) were -3.10, -1.74, -1.84; log2 (SL/M) were -1.89, -1.39, -0.53; log2 (C/M) were -2.46, -1.52, -1.44, respectively, all P < 0.05]. RT-PCR showed that the mRNA expressions of IL-1, IL-8 and ICAM-1 in group M were significantly higher than those in group N [IL-1 (2 -ΔΔCT): 4.63±0.24 vs. 1.01±0.13, IL-8 (2 -ΔΔCT): 6.28±0.13 vs. 1.02±0.09, ICAM-1 (2 -ΔΔCT): 2.90±0.18 vs. 1.02±0.12, all P < 0.05]. The mRNA expressions of IL-1, IL-8, ICAM-1 in SH, SM, SL and C groups were lower than those in group M [IL-1 (2 -ΔΔCT): 2.12±0.32, 1.71±0.07, 2.05±0.16, 1.66±0.13 vs. 4.63±0.24; IL-8 (2 -ΔΔCT): 3.89±0.13, 2.08±0.19, 2.98±0.20, 2.02±0.12 vs. 6.28±0.13; ICAM-1 (2 -ΔΔCT): 1.72±0.93, 1.34±0.14, 1.53±0.25, 1.17±0.12 vs. 2.90±0.18, all P < 0.05]. There was no significant difference among the SH, SM, SL and C groups. Conclusion:Shufeng Xuanfei Jiedu formula inhibits inflammatory damage in mice after influenza virus infection by down-regulating the expressions of IL-1, IL-8, and ICAM-1 inflammatory cytokine-related genes.

Objective To investigate the correlation between the expression of CD147 and MUC5ac in peripheral small cell lung cancer and the computed tomography (CT) signs.Methods Forty two cases of peripheral non-small cell lung cancer (NSCLC) confirmed by operation and pathology were examined by CT.The positive expression of CD147 and MUC5ac was detected by immunohistochemical staining and the relationship between the expression of CD147 and MUC5ac was analyzed.Results CD147 and MUC5ac were closely related to the lymphatic metastasis of peripheral non-small cell lung cancer (P ＜ 0.05).The positive expression of CD147 is significantly related to tumor size,deep lobulation,spinous process and lymphadenopathy (P ＜ 0.05).MUC5ac is significantly related to tumor size,deep lobulation,spiculation,vascular convergence sign,extrapleural fat Line disappearance,and mediastinal lymphadenopathy (P ＜0.05).Conclusions These results indicate that CD147 and MUC5ac play an important role in the invasion and metastasis of peripheral lung cancer.
RESUMO
ObjectiveTo investigate the regulatory effects of traditional Chinese medicine (TCM) Shufengxuanfeijiedu formula on Janus kinase signal transducer and activators of transcription (JAK-STAT) of lung tissues in mice with influenza viral pneumonia.Methods According to random number table, 60 mice were randomly divided into six groups with 10 mice in each group: normal group (N), model group (M), Tamiflu control group (C) and low (SL), medium (SM), high dose (SH) Shufengxuanfeijiedu formula groups. The mouse model of influenza virus pneumonia was reproduced by dropping of 0.05 mL 4LD50 inflluenza virus FM1 strain which can be adapted to lung tissue into the nose; while the N received nose instillation of 0.05 mL normal saline. After successful modeling for 2 hours, distilled water was given orally (by lavage) to N and M; Duffy (oseltamivir) 2.5 g·mL-1·d-1 was administrated to C; the TCM SL, SM, SH were intragastrically administered with different doses of shufengxuanfeijiedu decoction into the corresponding groups respectively (the ingredients of prescription: chrysanthemum, mulberry leaf, almond, platycodon root, forsythia, bupleurum etc. forming granules), according to the suitable dose of granules used for human body surface, the dose used for mouse surface area was calculated, the high dose means the dose used in the medium dose group doubled, the low dose means 1/2 dose used in medium group, once a day, once 0.2 mL for consecutive 4 days. Afterwards, the lung tissues were collected, the mouse differential gene expressions related to JAK-STAT pathway were detected by gene chip technology, the standards for screening of differential gene expression were as follows: up-regulated gene was P 1; down-regulation gene wasP < 0.05, and log2ratio < -1. The levels in lung tissue kinase (JAK) andγinterferon (IFN-γ) mRNA expressions were determined by real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-qPCR).Results Compared with those in N, the differential expression gene transcription activator, STAT5 [log2 (N/M) = 2.32], interleukin 4 receptor alpha subunit [IL4RA, log2 (N/M) = 4.77], interleukin 12 receptor [IL12R, log2 (N/M) = 1.58], JAK [log2 (N/M) = 2.41] were all obviously up-regulated, and IFN was significantly down-regulated [log2 (N/M) = -1.45] in M. Compared with those in M, C group IFN [log2 (C/M) = 1.51], various TCM dose groups [log2 (SL/M) = 1.46, log2 (SM/M) = 1.72, log2 (SH/M) = 1.40] differential expression gene IFN was significantly up-regulated, STAT5 [log2 (C/M) = -2.06, log2 (SL/M) = -1.41, log2 (SM/M) = -2.10, log2 (SH/M) = -1.89], IL4RA [log2 (C/M) = -2.52, log2 (SL/M) = -1.85, log2 (SM/M) = -2.74, log2 (SH/M) = -1.39), IL12R [log2 (C/M) = -1.48, log2 (SL/M) = -0.10, log2 (SM/M) = -1.58, log2 (SH/M) = -0.53], JAK [log2 (C/M) = -1.44, log2 (SL/M) = -0.88, log2 (SM/M) = -1.74, log2 (SH/M) = -0.53] were significantly down-regulated. In M, the JAK mRNA expression was obviously elevated (2-ΔΔCt: 3.17±0.94 vs. 1.01±0.13,P < 0.05), while the IFN-γ mRNA expression was decreased (2-ΔΔCt: 0.15±0.48 vs. 1.01±0.12,P < 0.05); compared with M, the JAK mRNA expressions in C, SM and SH groups were all obviously decreased (2-ΔΔCt: 2.02±0.63, 1.19±0.30, 1.59±0.67 vs. 3.17±0.94, allP < 0.05); while the IFN-γmRNA expressions in C, SL, SM and SH groups were elevated (2-ΔΔCt: 0.61±0.12, 0.41±0.13, 0.85±0.14, 0.78±0.20 vs. 0.15±0.48, allP < 0.05).Conclusions Shufengxuanfeijiedu formula can ameliorate the mice immune pathological injury of lung tissues induced by influenza virus by regulating JAK-STAT signal pathway and balancing Th1/2 via up-regulating the expression of IFN-γ.
