Objective:To explore the feasibility of mesencephalon progenitor cells as dopamine neuron's graft in treatment of Parkinson disease(PD) in rats. Methods: Animal model of PD were established in SD rats by 6 hydroxydopamine. Mesencephalon progenitor cells were obtained from 13 day old fetal rats. After in vitro proliferation and differentiation, the cells were planted into PD rat striatum. Results: Progenitor cells were expanded in an undifferentiated state with endothelia growth factor and basic fibroblast growth factor as mitogens. IL 1 and striatal culture media further increased the number of TH immunoreactive cells. Transplantation of these neurons relieved the rotation symptom of PD rats. Conclusion: Transplantation of mesencephalon progenitor cells has certain effects on PD rats.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Objective To observe the value of contrast-enhanced ultrasonography (CEUS) in quantitatively evaluating the evolution of the blood supply of rabbit liver VX2 tumor models in early stage. Methods Eighteen liver VX2 tumor models of rabbits were divided into 3 groups randomly (each n=6). CEUS was performed on the 10th, 15th and 20th day group after establishemnt, resepectively. Time intensity curve (TIC) was plotted, the rabbits' liver tumor and surrounding normal liver tissue were resected for immuno-histochemistry and microvessel density (MVD) count. Results CEUS showed that the rabbit liver VX2 tumor present a typical malignant tumor imaging fast-in and fast-out in early stage. TIC showed that the time to peak (TTP) of hepatic tumor is shorter than that of surrounding normal liver tissue in all three groups (P＜0.01), no statistical difference of tumor's TTP was detected among three groups (P>0.05). Absolute enhanced intensity (AEI) and MVD reduced in turn of 10th, 15th and 20th day group. MVD of tumor was higher in 10thday group than surrounding normal liver tissue (P＜0.01), while was equal in 15th day group (P>0.05) and lower in 20th day group (P＜0.01). AEI of liver tumor had positive correlation with MVD (r=0.83, P＜0.05). Conclusion AEI of TIC can be used to quantitatively assess the evolution of the blood supply in rabbit liver VX2 tumor models. The blood supply in early stage of rabbit liver VX2 tumor models shows a gradual descent process from abundant blood supply to medium blood supply and then low blood supply.

OBJECTIVETo assess the feasibility of a polymer material-expanded polytetrafluoroethylene (ePTFE) as wound covering.

METHODSForty-five Sprague Dawley (SD) rats inflicted with open wound on the back were divided into 3 groups, each group 15 rats. Wounds in the autograft group were covered with autologous skin. Wounds in the allograft group were covered with skin from 15 Wistar rats (donor). Wounds in the experiment group were covered with ePTFE. Wound healing in each group was observed with naked eye. Tissue specimens collected on 3rd, 7th, and 14th post-operative day (POD) respectively were stained with HE and examined under light microscope. Macrophages, lymphocytes and fibroblasts were quantified. IL-2 and IFN-gamma levels in the infiltrating mononuclear cells were assessed by immunohistochemistry with expression of gray value.

RESULTSWounds in rats of autograft group and experiment group healed well without redness, swelling or infection. Rejection was evident in the allograft group rats on 8th POD, including epidermis degeneration and focal necrosis in different degree, plus red swelling on wound edge. The numbers of macrophages, fibroblasts, lymphocytes in allograft group were significantly higher than those in autograft group and experiment group (P < 0.01). The average gray values of IL-2 and IFN-gamma of allograft group on 7th POD were 129 +/- 7 and 113.7 +/- 2.7, which were significantly lower than those in the experiment group (144 +/- 8, 137.3 +/- 1.9, respectively, P < 0.01) and allograft group (189 +/- 6, 180.3 +/- 3.7, respectively, P < 0.01).

CONCLUSIONSePTFE will induce minimal inflammatory response and foreign body reaction. It is unlikely to cause side effect when applied to wound surface for a prolonged period. Thus, it is suitable to use ePTFE as wound surface covering.

Abstract: Objective　To investigate the early diagnostic value of peripheral blood procalcitonin (PCT), C-reactive protein (CRP), fibrinogen (FIB) and D-dimer (D-D) levels in patients with pulmonary tuberculosis (PTB) complicated with bacterial pneumonia. Methods　A total of 102 patients who admitted to Department of Tuberculosis of Affiliated Nantong Hospital of Shanghai University from Jan 2021 to May 2022 were enrolled in this study and divided into a group (52 cases) with pulmonary tuberculosis (PTB) patients and a group (50 cases) with PTB patients complicated with bacterial pneumonia. The levels of PCT, CRP, FIB and D-D in the peripheral blood were measured, the differences and correlations in all indicators were compared among two groups. The sensitivity and specificity of these indicators in the early diagnosis of PTB complicated with bacterial pneumonia were analyzed by receiver operating characteristic (ROC) curve. Results　The levels of PCT, CRP, FIB and D-D in the peripheral blood from the PTB complicated with bacterial pneumonia group were 0.06 (0.04, 0.16) ng/mL, 38.00 (3.88, 96.10) mg/L, 4.51 (3.02, 6.07) g/L, and 0.59 (0.34, 1.88) mg/L, respectively, which were significantly higher than corresponding 0.04 (0.03, 0.04) ng/mL, 3.20 (0.84, 7.22) mg/L, 2.96 (2.48, 3.77) g/L, and 0.27 (0.17, 0.36) mg/L in the PTB group (Z=-4.784, -5.233, -3.853, -4.199, all P<0.001). Furthermore, the levels of CRP and FIB in the PTB complicated by bacterial pneumonia group were highly positively correlated (r=0.855, P<0.001). The area under the ROC curve (AUC) of PCT, CRP, FIB and D-D for early diagnosis of PTB complicated with bacterial pneumonia were 0.757, 0.794, 0.747 and 0.764, respectively. In addition, the AUC obtained by simultaneous measurement of PCT, CRP, FIB and D-D was as high as 0.916, and the sensitivity and specificity of diagnosing PTB complicated with bacterial pneumonia were increased to 85.7% and 96.9%, respectively, which were higher than those of individual indicators. Conclusions　Levels of peripheral blood PCT, CRP, FIB, and D-D all show varying degrees of increase in patients with PTB complicated with bacterial pneumonia, and detecting the levels of all four markers, rather than any single marker, can assist in early monitoring whether the tuberculosis patients are complicated with bacterial pneumonia.

Objective To assess the clinical value of 18F-FDG PET/CT for the prediction of postoperative recurrence and metastasis in patients with NSCLC.Methods Eighty-five patients (64 males,21 females; average age:58.0 years) with NSCLC were enrolled.All patients underwent 18 F-FDG PET/CT within one week before surgical operation and 3 months after the operation.The diagnosis of recurrent cancer and metastasis was confirmed by pathologic findings,other imaging modalities and clinical follow-up.The diagnostic efficacy of PET/CT was calculated and the predictors for postoperative recurrence and metastasis were analyzed.x2 test and two-sample t test were used for statistical analysis.Results Among 85 patients,43 had recurrence and metastasis post operation.The postoperative recurrence and metastasis were detected by 18F-FDG PET/CT in 9.3％(4/43) within 6 months,30.2％(13/43) within 1 year,76.7％(33/43) within 2 years and 97.7％(42/43) after 2 years.The sensitivity,specificity,accuracy of 18F-FDG PET/CT for the detection of recurrent tumor and metastasis were 97.7％ (42/43),95.2％ (40/42),96.5％ (82/85) respectively.The preoperative cancer staging,size and SUVmax of primary tumor were significant factors for the prediction of postoperative tumor recurrence and metastasis within 2 years (x2 =12.360,t=3.281 and 2.465,all P＜0.05),but not gender,age or pathological findings (x2 =0.639,0.012 and 3.800,all P＞0.05).Conclusions 18F-FDG PET/CT has an important role for the detection of postoperative recurrence and metastasis in patients with NSCLC.Preoperative cancer staging,size and SUVmax of the primary tumor might be the predictive factors for postoperative tumor recurrence and metastasis within 2 years.

OBJECTIVE: To explore the effect of delta-opioid receptor (DOR) in electroacupuncture (EA) protecting the brain against acute ischemic injury. METHODS: Fifty-one rats were randomly divided into sham ischemia group, ischemia group, sham EA group, EA group, and EA+DOR antagonist (naltrindole) group. Transient focal cerebral ischemia (1 hour) was induced in rat brain by middle cerebral artery occlusion (MCAO) method. EA was applied on Shuigou (GV 26) and Neiguan (PC 6) for 30 min, starting immediately after the onset of reperfusion. Neurological deficit scores and volume of cerebral infarction were detected after 24-hour reperfusion. Other 12 rats were randomly divided into sham ischemia group, ischemia group, EA group and EA + naltrindole group. DOR protein expressions were assessed by Western blotting after 24-hour reperfusion. RESULTS: In comparison with the ischemia group and sham EA group, EA significantly reduced ischemic infarction and neurological deficits (P<0.05); EA significantly increased the expression of 60 kD DOR protein (P<0.05) and tended to increase that of 36 kD DOR protein (P>0.05). When naltrindole was combined with EA, the naltrindole completely abolished the EA-induced protection in ischemic infarction and neurological deficits, and also arrested the expression of DOR. CONCLUSION: EA can up-regulate DOR expression and protect the brain from ischemia-reperfusion injury.
