150-day-old Tianfu ducklings were divided into three groups,and fed with diets as follows :Zn deficient (22. 9 mgZn per kg diet),controls(100 mg Zn per kg diet) and Zn toxic (1 300 mg Zn per kg diet) for seven weeks (Zn deficiency,ZD)or four weeks (Zn toxieity,ZT). The ANAE+ positive ratios of the peripheral blood T-lymphocytes were much lower (P＜0.01 ) in Zn deficient and toxic groups than in the control group. The results showed that Zn deficiency and toxicity would suppress the development of T-lymphocytes and reduce the peripheral blood T-lymphocyte populations. Potential mechanisms underlying these observations are also discussed.

Chemotherapy completion rate can reflect the tolerance and compliance of patients to chemotherapy. Poor tolerance may result in delay or suspension of the comprehensive treatment plan, thus affect the efficacy of cancer treatment. Evaluating methods to improve the completion rate of chemotherapy and reduce the occurrence of delayed chemotherapy has gained increasing attention and is the significant area of study in the field of cancer treatment. Studies have shown that Chinese medicine combined with chemotherapy could improve the quality of life in patients with stage IIIB/IV non-small-cell lung cancer (NSCLC).

OBJECTIVETo explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

METHODSTotally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine. Those in the observation group received electrical stimulation at Baihui (DU20), Yintang ( EX-HN3), and Neiguan (PC6) before dexmedetomidine anesthesia. The cognitive function of patients at preoperative day 1 and postoperative day 1 was respectively evaluated by Mini-Mental State Examinations (MMSE). Serum NSE, S-100β, IL-1β, IL-6, and TNF-α levels were detected in the two groups before intervention and immediately after intervention using ELISA.

RESULTSMMSE scores of two groups were significantly reduced at post-intervention day 1, as compared with one day before intervention. MMSE score of the observation group at post-intervention day 1 was (23.15 ± 1.87) points, significantly higher than that of the control group [ (19.34 ± 1.64) points , (P < 0.05)]. The postoperative cognitive dysfunction (POCD) incidence rate of the observation group was 16.4% (10/61), significantly lower than that of the control group [39.3% (24/61); P < 0.05]. Compared with before intervention, NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels of the two groups increased (P < 0.05). Post-intervention NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels were significantly lower in the observation group than in the control group (P < 0.05).

CONCLUSIONDexmedetomidine combied electrical stimulation could effectively prevent the occurrence of postoperative cognition, and reduce levels of NSA, S-100β, IL-1β, IL-6 and TNF-α.

Objective To observe the effect of postoperative analgesia of Ropivacaine combined Dexmedetomidine for transversus abdominis plane (TAP) block in laparoscopic surgery. Methods 60 patients underwent selective laparoscopic hernia repair were randomly divided into two groups: Ropivacine plus Dexmedetomidine group (Rpd group): Dexmedetomidine 1.0 μg/kg + 0.4% Ropivacine 30 ml was injected into bilateral TAP, and Ropivacine group (R group): saline 1 ml+0.4% Ropivacine 30 ml was injected into bilateral TAP. Blood pressure and heart rate on beginning of the surgery, 1 h during surgery and leaving the operating room, VAS of immediate postoperative period, 4 h, 6 h, 8 h, 12 h, 24 h after the surgery, analgesic duration and incidence of nausea and vomiting of the two groups were recorded. Results Two groups have no difference in blood pressure and heart rate in all time points (P > 0.05), VAS score of 6 h, 8 h, 12 h after surgery in Rpd group were lower than in R group (P < 0.05), and VAS score of postoperative period, 4 h, 24 h after the surgery had no difference between the two groups (P > 0.05). Sensory block duration in Rpd group was longer than in R group (P < 0.05). Incidence of nausea and vomiting of the two groups had no difference in two groups (P > 0.05). Conclusions Ropivacaine combined Dexmedetomidine for Transversus Abdominis Plane block in laparoscopy patients can significantly prolong the analgesic duration.

OBJECTIVETo explore the mechanism of Shenqi compound recipe (SQCR) anti-earlier diabetic artherosclerosis in GK rats.

METHODFour-month specefic pathogen free (SPF) GK rats were divided randomly according to blood glucose level into four groups: model group (5 mL x kg(-1) x d(-1) sterile water), ramipril group (positive control, 1 mg x kg(-1) x d(-1)), SQCR low dosage (0.72 g x kg(-1) x d(-1)) and SQCR high dosage group (2.88 g x kg(-1) x d(-1)) and Wistar rats as normal control group(5 mL x kg(-1) x d(-1) sterile water). GK rats took high-fat diet freely and meanwile were injected N-omega-nitro-L-arginine methyl ester (L-N-AME) intra-peritoneally with the dose of 10 mg x kg(-1) x d(-1) in order to induce earlier diabetic artherosclerosis, while normal control group took regular diet and were injected normal saline intra-peritoneally. In the experiment periods, each group was administrated correspondent substance respectively for 32 d. At the end, sampling blood by abdominal aorta and picking aorta on ice. Determined monocyte chemoattractant protein-1 (MCP-1) concentration by ELISA, messenger ribonucleic acid (mRNA) expression of MCP-1 and peroxisome proliferator-activated receptor gamma (PPARgamma) in aorta by reverse transcriptase PCR (RT-PCR).

RESULTConcentrations of MCP-1 in serum in SQCR low and high dosage groups and the mRNA expression of MCP-1 in SQCR high dosage group were all decreased significantly compared with model group (P < 0.05). The mRNA expression of PPARgamma in SQCR low and high dosage groups all increased compared with model group (P < 0.05 or P < 0.01).

CONCLUSIONInhibiting the mRNA and protein expression of MCP-1 and upregulating the mRNA expression of PPARgamma in aorta might be contribute to SQCR anti-earlier diabetic artherosclerosis in GK rats partly.

The aim of the present study was to investigate the effects of prenatal alcohol exposure (PAE) on the development and cell differentiation of retina in offspring. The mouse model of PAE was made. HE staining and immunofluorescent labeling were carried out to visualize the structure, development and cell differentiation of the retina from postnatal day 0 (P0)-P30 offspring. The results showed that PAE can lead to the retardation of retinal development, the reduction of number of bipolar cells and horizontal cells, the disorder of horizontal cells' polarity, as well as the retinal thickening in a dose-dependent manner. The data suggest that alcohol exposure during pregnancy can lead to the developmental retardation of retina and decreased number of bipolar cells and horizontal cells in the retina of offspring.

Objective:To investigate the effect of right stellate ganglion block (RSGB)-serratus anterior plane block (SAPB) combined with general anesthesia in thoracoscopic radical resection of lung cancer.Methods:A total of 90 patients who planned to undergo thoracoscopic radical resection of lung cancer in Xiangya Changde Hospital from March 2020 to September 2021 were prospectively selected and divided into 3 groups by random number table method: general anesthesia group (G group), (SAPB)+ general anesthesia group (SG group), RSGB+ SAPB+ general anesthesia group (RSG group), 30 cases in each group. The SG group received SAPB on the operative side before general anesthesia, and the RSG group received RSGB+ SAPB on the operative side before general anesthesia. After the blocking effect was determined, all patients were given general anesthesia in the same scheme according to their weight, and patients were given patient-controlled intravenous analgesia (PCIA) after surgery. The mean arterial pressure (MAP) and heart rate (HR) were recorded before anesthesia (T 0), before intubation (T 1), 1 min after intubation (T 2), 5 min after intubation (T 3), at extubation (T 4) and 5 min after extubation (T 5). The intraoperative dosage of remifentanil, incidence of nausea and vomiting (PONV) within 24 hours after surgery, number of additional PCIA within 24 hours, the Visual Analogue Scale (VAS) of static and dynamic pain, the Bruggrmann Comfort Scale (BCS) and Richard Campbell Sleep Questionnaire (RSCQ) 24 hours after surgery were recorded. Results:Compared with T 0, the MAP and HR in 3 groups were increased 1 min after intubation (T 2) and at extubation (T 4), but the increases in RSG group were significantly less than those in G and SG groups (all P<0.05). The remifentanil dosage, PONV incidence and PCIA supplemental times in SG and RSG groups were less than those in G group, and the BCS score and RSCQ score were higher than those in G group (all P<0.05); the BCS score and RSCQ score in RSG group were higher than those in SG group (all P<0.05). Conclusions:RSGB+ SAPB combined with general anesthesia in thoracoscopic radical resection of lung cancer has little circulation fluctuation, good postoperative analgesia effect, less adverse reactions and high comfort level.
