Objective To test different expression protein markers of the serum from B-cell non-Hodgkin lymphoma(B-cell NHL) between diffuse large B-cell lymphoma(DLBCL) and follicular lymphoma(FL)patients using sudace enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS)protein chip technology. Further, to test different expression of the protein markers of B-eell NHL patients after chemical therapy in order to discuss clinical significance. Methods Different expression of protein markers were analysed in serum between 54 B-cell NHL patients and 27 healthy volunteers by using SELDI-TOF-MS WCX-2 pertein chip. Meanwhile different expression of protein markers relative to pathology classification between 23 DLBCL patients and 12 FL patients were screened; and protein markers which affected prognosis of 23 DLBCL patients were screened. Results There were five specific marker proteins in 54 B-cell NHL patients and 27 healthy volunteers. Their relative molecular weights were 7974, 15 938, 3398,8564, and 8692. The protein markers of 7974 and 15 938 were at high level in patients and the protein markers of 3398, 8564 and 8692 were at low level in patients. There were two protein markers which affected the prognosis, with better outcome when the expression of 4795 and 4998 were increased. Conclusion SELDI-TOF-MS protein chip technology is a quick, easy and convenient method, with high-throughput analyzer which can screen several relatively specific protein markers from the serum of patients to diagnose B-cell NHL The relatively specific protein markers can be used to make pathology classification and to judge the prognosis of B-cell NHL, and have better clinical value.

Objective To research correlation of serum protein spectrometry and lymphoma markers for diffuse large B cell lymphoma (DLBCL) patients. Whether there is relative between the protein and prognosis will be further researched. Methods Serum protein spectrometry of 62 DLBCL patients was detected by the SELDI-TOF-MS technique and Weak cation exchange 2 (WCX2) chip. Lactate dehydrogenase (LDH) was detected by biochemistry method. Beta-2-microglobulin (β2-MG) and cancer antigen125(CA125)were detected by enzyme-linked immunosorbent assay (ELISA). The level of LDH, β2-MG and CA125 for DLBCL patients between 11×103~12×103 protein expressed positively and negatively was analyzed. Meanwhile,correlation analysis and survival analysis were done. Results LDH, β2-MG and CA125 in 11×103~12×103protein expressed positive group were (523.30±435.96)U/L, (3.23±1.24)mg/L, (81.07±61.39)U/L respectively,and they were higher than that in negative group (P<0.05). 11×103~12×103 protein was positive correlated to LDH, β2-MG and CA125 (P<0.01). The survival time in 11×103~12×103 protein expressed in positive group,in which median survival time was 11 months, was shorter than that in negative group(P <0.01). The survival time in LDH normal group was longer than that in increased group(P <0.01). The survival time of β2-MG and CA125 had no significant difference between increased group and normal group. Conclusion LDH and 11×103~12×103 protein are expected to be prognosis indicators for DLBCL patients.

Objective To investigate the dynamic changes and coordination of macrocirculation and microcirculation in rats with severe hemorrhagic shock and septic shock. Methods A total of 20 male Sprague-Dawley rats (450~550 g) were randomly divided into two groups (n = 10) : hemorrhagic shock group (H-Shock) and septic shock group (S-Shock). 40% of the systemic blood volume was withdrawn in 1 hour in H-Shock group.While in the S-Shock group, cereal ligation and puncture (CLP) was performed and then the abdomen was closed.Mean arterial pressure (MAP) and the end-tidal carbon dioxide (ETCO2) were recorded continuously. Cardiac ultrasonography and sublingual microcirculation were performed per hour till 12 hours or the rat die (End). A total of 12 hours were observed or the rat die. Arterial blood gas was measured at baseline (BL) , MAP ≤ 65 mmHg (Shock) and at the termination of observation respectively. Results The values reflect macrocirculation or microcirculation in the H-Shock group were all decreased than BL respectively at each time. In the S-Shock group, the values that reflect macrocirculation such as MAP, ETC02 and cardiac output (CO) showed no significant changes within 3 hours (P> 0.05) , while the values of microcirculation were decreased compared with BL respectively at each time (P < 0.05). With the progress of shock, the pH was decreased compared with BL in both groups, while the level of Lac were increased (P < 0.05). Conclusions The changes of macrocirculation and microcirculation in severe hemorrhagic shock are basically the same; while they are inconsistent in septic shock, the changes of microcirculation occurred earlier than that of macrocirculation.

Objective:To evaluate the clinical effects of anterolateral thigh free flap with fascia lata in the repair of dura mater defect after resection of head squamous cell carcinoma.Methods:From June 2016 to June 2018, Xijing Hospital of Air Force Medical University applied the free transplantation of anterolateral thigh flap with fascia lata to repair the dura mater defect of 12 patients with head squamous cell carcinoma, including 9 males and 3 females, aged from 35 to 74 years. The size of scalp soft tissue defects in patients after carcinoma resection ranged from 12 cm×10 cm to 24 cm×21 cm, and the size of dura mater defect of patients ranged from 7 cm×6 cm to 16 cm×14 cm. The size of flap of patients ranged from 14 cm×12 cm to 27 cm×24 cm, and the size of fascia lata ranged from 8 cm×7 cm to 17 cm×15 cm. The superficial temporal artery and middle temporal vein were connected by end to end anastomosis with the first musculocutaneous perforating branch of the descending branch of lateral femoral artery and its accompanying vein. The flap donor area was transplanted with autologous split-thickness skin graft from trunk and fixed with packing. Postoperative survival of flaps and skin grafts was observed. The patients were followed up regularly. The cranial magnetic resonance imaging was performed to observe the recurrence of intracranial tumors and dural integrity, shape of the flap and whether the donor site region was left with significant dysfunction were observed.Results:All the flaps and skin grafts survived well in 12 patients after surgery. Ten patients had primary healing at the edge of the flap suture; 2 patients had local sinus tract formation at the suture site of flap, with a small amount of cerebrospinal fluid leakage, and were recovered after outpatient dressing change. The patients were followed up for 10 to 36 months, and 3 patients with tumors involving in the dura mater sagittal sinus region had postoperative intracranial tumor recurrence. The tumor was resected again. All the patients had good dural integrity. The flaps of all patients were in good shape, and no obvious dysfunction remained in the flap donor site.Conclusions:Free transplantation of anterolateral thigh flap with fascia lata is an effective and reliable method to repair the dura mater defect following head squamous cell carcinoma resection. It can repair the scalp and dura mater defects caused by the invasion of squamous cell carcinoma and provide possibilities for skull reconstruction.

Plasticity in the glutamatergic synapses on striatal medium spiny neurons (MSNs) is not only essential for behavioral adaptation but also extremely vulnerable to drugs of abuse. Modulation on these synapses by even a single exposure to an addictive drug may interfere with the plasticity required by behavioral learning and thus produce impairment. In the present work, we found that the negative reinforcement learning, escaping mild foot-shocks by correct nose-poking, was impaired by a single in vivo exposure to 20 mg/kg cocaine 24 h before the learning in mice. Either a single exposure to cocaine or reinforcement learning potentiates the glutamatergic synapses on MSNs expressing the striatal dopamine 1 (D1) receptor (D1-MSNs). However, 24 h after the cocaine exposure, the potentiation required for reinforcement learning was disrupted. Specific manipulation of the activity of striatal D1-MSNs in D1-cre mice demonstrated that activation of these MSNs impaired reinforcement learning in normal D1-cre mice, but inhibition of these neurons reversed the reinforcement learning impairment induced by cocaine. The results suggest that cocaine potentiates the activity of direct pathway neurons in the dorsomedial striatum and this potentiation might disrupt the potentiation produced during and required for reinforcement learning.
