OBJECTIVE: To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors. METHODS: Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography. RESULTS: Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05). CONCLUSION The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.

In this study, the texture analyzer acupuncture pressure sensor was used to objectively characterize the "herb soaking with exact amount of water" for moistening process of ginseng. The single factor rotation experiment was used to investigate the effects of puncture speed, puncture depth and puncture site on puncture force and work. According to ginseng processing method in Chinese Pharmacopoeia, ginseng medicinal materials with diameters of about 1 cm and 2 cm were selected, and puncture experiments were carried out at the set measurement time to determine the hardness, work and water absorption of the ginseng moistening process. The endpoint threshold for the ginseng softening process was determined and verified. To reflect the actual internal conditions of the ginseng softening process, the puncture depth was preferably 70%, and the puncture speed was 30 mm·min~(-1). In the ginseng moistening process, the softening hardness and the puncture work were in accordance with the first-order kinetic equation y=a×exp(-k×x). The 0 h initial hardness a of 1 cm and 2 cm ginseng herbs were 289.8 N and 1 227 N, and the rate constants K were 0.149 4 N·h~(-1) and 0.100 7 N·h~(-1), respectively. After the ginseng was completely softened, the force required for puncture was 10 N, which can be used as the standard for "drug penetration". At this time, the water absorption rate of ginseng was 70%-100%. The softening time of ginseng with a diameter of 1 cm was about 20-22 h, and the softening time of ginseng with a diameter of 2 cm was about 40-46 h. A needle-type pressure sensor was used to accurately determine the end point of the softening process of ginseng and reduce the loss of active ingredients. The study results provide reference for the softening process kinetics and the process intelligent monitoring of other dried roots and rhizomes.

Objective: To explore the diagnosis, treatment and prognosis of autoimmune hemolytic anemia (AIHA) after allo-HSCT in patients with thalassemia major (TM). Methods: A retrospective analysis of AIHA status after allo-HSCT in 291 TM patients from July 2007 to December 2017 was conducted. Results: Five of the 291 TM patients (1.72%) were diagnosed with post-transplant AIHA. The median time of AIHA was 7 (5-12) months after HSCT. All post-transplant AIHA patients were positive in direct and indirect Coombs test, the main clinical manifestations were dizziness, fatigue, pale complexion, skin and sclera yellow, and soy sauce urine. The incidence of AIHA was higher after unrelated donor transplantation (6.36%, 4/63) compared with that of sibling donor transplantation (0.43%, 1/228). One patient who received only prednison was dead. Four patients who received rituximab combined with prednisolone were alive, Coombs test in two of them were negative. Conclusions: AIHA after allo-HSCT developed in 1.72% patients with TM. Monitoring of Coombs test was important for diagnosis of post-transplant AIHA. The incidence of post-transplant AIHA was higher in unrelated donors compared with that of sibling donors transplantation. Treatment of rituximab combined glucocorticoid was effective strategy for post-transplant AIHA.

OBJECTIVETo investigate whether vitamin Bphotochemical pathogen reduction technology(PRT) treatment may lead to increase white cell- and platelet- derived cytokines release from platelets during storage.

METHODSSixty milliliters of leukodepleted apheresis platelets were collected from 20 healthy donors, then were divided into 2 parts: one part (30 ml) remained untreated to serve as control, while the other part was treated with vitamin B-UVB photo-chemical technology as experimental group. During 7 d of storage under standard blood bank conditions, platelet coun-ting (PC), platelet distribution width (PDW), mean platelet volume (MPV), white cell-derived cytokines (IL-1β, IL-2, IL-6, IL-8, TNF-α and IFN-γ) and platelet-derived cytokines (CCL3, CCL5, TGF-β-1 and PF4), P-selectin and phosphatidyl serine (PS) were analyzed on day 1, 3, 5 and 7 of storage, respectively.

RESULTSNo signi-ficant differences were observed on PC, PDW and MPV between the experimental and control groups, respectively. The higher levels of platelet-derived cytokines were detected and reached a plateau after 5-7 days of storage, and the cyto-kines showed significant increase in experimental group compared with the control group. PS expression increased signi-ficantly in experimental group as compared with control group on day 3, 5 and 7 of storage, respectively. The accumula-tion of P-selectin was significant higher in experimental group than that in control group on day 5 and 7 of storage (P<0.05). The white cell-derived cytokines were not elevated by PRT treatment during 7 days of storage.

CONCLUSIONThe PRT-treated platelets are the main source of released cytokines during storage of PRT treatment. The levels of platelet-derived cytokines reach a plateau after 5-7 days of storage, most likely due to accelerated platelet activation and apoptosis.

The effects of the balance changes of pigment epithelium growth factor (PEDF) and vascular endothelial growth factor (VEGF) in whole-body and retinal tissue on rats with oxygen-induced retinopathy were investigated. Forty-eight neonatal SD rats at the age of 7 days were randomly divided into 4 groups. The neonatal rats in experimental groups were exposed to 75% to 80% oxygen for 5 days and then to normal air, and those in control groups were kept feeding in normal air. At the age of 17 and 22 days, all the neonatal rats received retina angiography with FITC-dextran and the pathological changes of retinal vessels and perfusion were observed. HE staining of the tissue section and the number counting of endothelial cells extending beyond the inner limiting membrane were performed to evaluate the endothelial proliferation. Immunohistochemistry was applied to detect the expression of PEDF and VEGF in retinal tissue, and ELISA to detect their expression in serum. A hypoxic-ischemic proliferation of retina and more endothelial cells extending beyond the inner limiting membrane were found in the neonatal rats in both experimental groups of 17-day old and 22-day old as compared with those in control group with the difference being statistically significant (P<0.01). VEGF staining of the rats in the 17-day old experimental group was significantly stronger, with an increasing positive rate, than that of the rats in the 17-day old control group (P<0.01). PEDF staining of the rats of 22 days old was weaker than that of the rats of 17 days old in the experimental groups (P<0.01). There was no significant difference in serum VEGF concentration among all groups (P>0.05). The serum PEDF concentration in the rats of 17 days old in experimental group was decreased significantly as compared with that in the rats of 17 days old in control group (P<0.01), and in experimental groups, the serum PEDF concentration of the rats of 22 days old was increased as compared with that of the rats of 17 days old (P<0.01). In conclusion, the obviously decreased serum PEDF concentration and the abnormal enhanced expression of VEGF density in local retinal tissue broke down the balance of PEDF/VEGF in whole-body or local tissues, which might play an important role in retinal vascular proliferation.

Objective To study the optimal waist circumference (WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China.
Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome (MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared.
Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men.
Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.

OBJECTIVETo explore the protective effect and the mechanism of controlled hypotension induced by transcutaneous electrical acupoint stimulation (TEAS) combined with general anesthesia.

METHODSSixteen male Beagles were randomly divided into a group of controlled hypotension induced by simple general anesthesia (control group) and a group of controlled hypotension induced by TEAS combined with general anesthesia (observation group). All the animals were administered with combination of Isoflurane and Sodium Nitroprusside (SNP) for controlled hypotension without TEAS until the arterial pressure was lowered to 30% basic mean arterial pressure (MAP) for 60 min. In the observation group, TEAS (2 Hz/100 Hz, 3-5 mA) was applied to "Hegu" (LI 4) "Zusanli" (ST 36), "Sanyinjiao" (SP 6) and "Quchi" (LI 11) from the beginning of physiological conditions stability to the end of maintained low MAP for 60 min, but there was no TEAS in control group. The changes of MAP, the left intraventricular pressure (LIVP), T wave and ST-T segment of II lead electrocardiogram (ECG) were monitored with the physiological signal acquisition system, and myocardial apoptosis was detected by TUNEL method.

RESULTSAll the animals could maintain stable required low blood pressure. At one hour after cease of controlled hypotension, MAP of (109.56 +/- 6.14) mmHg returned to the basic level in the observation group, while MAP of (84.91 +/- 6.36) mmHg was still lower than its basic MAP of (111.02 +/- 4.15) mmHg in the control group (P < 0.05), showing significant difference in MAP between the two groups (P < 0.05). -dp/dtmax of (3156.32 +/- 332.82) mmHg/s showed significant lower than its basic value of (4585.33 +/- 638.55) mmHg/s when blood pressure increased for 1 h in the control group (P < 0.05), but there was no difference in the observation group. When the objective low MAP maintaining for 60 min the ST segment was decreased significantly in the control group (P < 0.05), but there was no difference in the observation group. The numbers of positive apoptosis cardiocytes in the observation group were (24.67 +/- 2.45) cells/mm2, which were significantly fewer than (37.89 +/- 1.90) cells/mm2 in the control group (P < 0. 05).

CONCLUSIONSTEAS combined with general anesthesia for controlled hypotension can significantly shorten restoration time of MAP, help to improve myocardial ischemia and the cardiac functional recovery and reduce myocardial apoptosis so as to produce myocardial protection.
