Along with the development of economy and society, type 2 diabetic mellitus (T2DM) has become one of the most common diseases at the global level. As one of the complications of T2DM, diabetic neuropathic pain (DNP) stubbornly and chronically affects the health and life of human beings. In the pain field, dorsal root ganglion (DRG) is generally considered as the first stage of the sensory pathway where the hyperexcitability of injured neurons is associated with different kinds of peripheral neuropathic pains. The abnormal electrophysiology is mainly due to the changed properties of voltage-gated sodium channels (VGSCs) and the increased sodium currents (I(Na)). Curcumin is an active ingredient extracted from turmeric and has been demonstrated to ameliorate T2DM and its various complications including DNP effectively. The present study demonstrates that the I(Na) of small-sized DRG neurons are significantly increased with the abnormal electrophysiological characteristics of VGSCs in type 2 diabetic neuropathic pain rats. And these abnormalities can be ameliorated efficaciously by a period of treatment with curcumin.

Objective To evaluate the feasibility and clinical effect of Argon plasma coagulator in simple enucleation for small renal cell carcinoma. Methods On the basis of successful performing the animal experience of coagulating therapy on the wound tissue during partial nephrectomy with Argon plasma coagulator in rabbit models, 10 cases of simple enucleation for small renal cell carcinoma with Argon plasma coagulator were accomplished. Results Both with the standard of stopping bleeding of wound tissue by Argon plasma coagulator and with the standard of re-spraying the wound tissue for 2 s after stopping bleeding using Argon plasma coagulator, the depth of wound tissue necrosis without blocking the renal pedicle is deeper than that with blocking the renal pedicle(P=0. 012 and P=0. 002, respectively).If the wound tissue was re-sprayed for 2 s after stopping bleeding by Argon plasma coagulator, the depth of the wound tissue necrosis without blocking the renal pedicle was deeper than that just with blocking the renal pedicle(P=0. 007 and P=0. 002,respectively). In the part of application in clinical, all procedures were successfully completed. The mean operative time was 163 min (range, 100-210 min) and mean blood loss was 230 ml (range, 100-400 ml). Drainage tube was pulled out 1 month after operation in 1 case for being allergic to absorbable hemostatic gauze, and the mean pulling drainage tube out time in others was 4. 2 d (range, 3-5 d). During a mean follow-up of 22 months (range, 10-38 months), no local tumor recurrence and distant metastasis was found. Conclusion Argon plasma coagulator can be used in simple enucleation for small renal cell carcinoma, and the clinical effectiveness is ideal.

Objective To explore the protective effects of proanthocyanidins pretreatment on intestinal function after cerebral ischemia-reperfusion injury. Methods 24 Sprague-Dawley rats were randomly divided into sham group (group A, n=8), ischemia-reperfusion group (group B, n=8) and proanthocyanidins pretreatment group (group C, n=8). The model of cerebral ischemia-reperfusion injury in rats was established according to Longa's method. Group C was intraperitoneally injected with proanthocyanidins 10 mg/(kg ⋅ d), group A and group B were injected with normal saline for 5 consecutive days. 1 and 3 days after cerebral ischemia-reperfusion, ileum myoelectric slow wave and smooth muscle contractility, the activity of superoxide dismutase (SOD) and content of malondialdehyde (MDA) were measured, the content of the serum TNF-α was tested with ELISA kit, ileum tissues were tested with hematoxylin eosin (HE) staining and used for measuring the moisture content. Results Compared with group B 1 and 3 days after cerebral ischemia-reperfusion, the intestinal mucosa injury relieved, the intestinal mucosa score decreased (P<0.05) and the number of infiltrated inflammatory cell decreased in group C; the frequency of slow wave and contraction trended to increase (P>0.05), and the amplitude increased (P<0.05) in group C; the serum SOD activity increased (P<0.05), and the content of MDA and TNF-α decreased (P<0.01) in group C; the intestinal moisture content reduced (P<0.01) in group C. Conclusion Proanthocyanidins pretreatment can protect intestinal function from injury after cerebral ischemia-reperfusion.

The clinical study was conducted to further evaluation the effectiveness and safety of Fangfeng Tongsheng granule in the treatment of sub-acute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome). In the block randomized, multi-centered study, totally 108 patients were enrolled and assigned to two groups: 72 patients in the test group and 36 patients in the placebo control group. Those in the test group took Fangfeng Tongsheng granule with the dose of 3 g, twice a day, while those in the control group were give simulated agent granules with the same dose. The therapeutic course lasted for 14 days. Their efficacies in TCM syndrome, dermal symptoms and adverse events were observed. According to the test results, except for the one exit case, all of the remaining 108 cases, including 71 in the test group, and 36 in the control group, completed the clinical trial. As for the efficacy of TCM syndrome, after the medication for 2 weeks, the cure rate was 33.81% (24/71) in the test group and 0% (0/36) in the control group (P < 0.01), with a statistical difference between the two groups. Regarding the TCM score, after the medication for 2 weeks, the test group decreased by (12.82 +/- 7.96), while the control group decreased by (3.67 +/- 4.12), indicating a statistical difference between the two groups. As for the efficacy of dermal symptoms, after the medication for 2 weeks, the cure rate was 25.35% (18/71) in the test group and 0% (0/36) in the control group, with a statistical difference between the two groups. Regarding the dermal symptom score, after the medication for 2 weeks., the test group decreased by (10.04 +/- 7.17), while the control group decreased by (2.33 +/- 3.57), indicating a statistical difference between the two groups. There was no significant adverse event caused by Fangfeng Tongsheng granule. In conclusion, Fangfeng Tongsheng granule was effective and safe in treating subcute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome).

OBJECTIVETo explore the dosimetric variance in forward intensity modulated radiotherapy (IMRT) based on 4D CT and 3D CT after breast conserving surgery.

METHODSSeventeen patients after breast conserving surgery underwent 3D CT simulation scans followed by respiration-synchronized 4D CT simulation scans at free breathing state. The treatment plan constructed using the end inspiration (EI) scan was then copied and applied to the end expiration (EE), and 3D scans and dose distribution were calculated separately. Dose-volume histograms (DVHs) parameters for the CTV, PTV, ipsilateral lung and heart were evaluated and compared.

RESULTSThe CTV volume difference was biggest between T0 and 3D CT, and the volume difference was 4.10 cm(3). Mean dose of PTV at EE was lower than that at EI (P = 0.019), but there were no statistically significant difference between 3D and EI, EE (all P > 0.05). The homogeneity index (HI) at EI, EE, 3D plans were 0.149, 0.159 and 0.164, respectively, and a significant difference was only between EI and EE (P = 0.039). The highest conformal index (CI) was at EI phase (P < 0.05), and there was no significant difference between EE and 3D (P = 0.758). The V(40) and V(50) of ipsilateral lung at EE phase were lower than that at EI (P < 0.05). There were no significant differences in all the indexes for heart (P > 0.05).

CONCLUSIONSThe breast deformation during respiration may be disregarded in whole breast IMRT. PTV dose distribution is significantly changed between EI and EE phases, and the differentiation of the lung high dose area between EI and EE phases may be induced by thorax expansion. 3D treatment planning is sufficient for whole breast forward IMRT, but 4D CT scans assisted by respiratory gating ensures more precise delivery of radiation dose.
