RESUMEN
Objective: To observe the effects of electroacupuncture (EA) with three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) on the apoptosis of neurons and c-Jun N-terminal kinase (JNK) signaling pathway in the hippocampus of rats with vascular dementia (VD), and explore the mechanism of EA intervention for VD. Methods: Fifty male Sprague-Dawley rats were randomly divided into a model group, a sham operation group, a 100 Hz EA group, a 2 Hz EA group, and a 2 Hz/100 Hz EA group, with ten rats in each group. The VD model rats were established by repeated ischemia-reperfusion of bilateral common carotid arteries. The rats in the EA groups received EA intervention at Baihui (GV20), Dazhui (GV14), Geshu (BL17) and Zusanli (ST36), once a day for 14 d. Afterward, Morris water maze was used to examine the learning and memory performances of the rats in each group, hematoxylin-eosin staining to observe the histomorphological changes in the hippocampal CA1 region, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling to test the apoptosis of neurons in the hippocampal CA1 region, and Western blot to detect the protein expression levels of JNK, phosphorylated JNK (p-JNK), Caspase-8, and Caspase-3 in the hippocampus tissue. Results: Compared with the sham operation group, the escape latency of the model group in water maze test was prolonged; the number of crossing the original platform was decreased (P<0.01); the hippocampal neurons were severely damaged and the number of surviving neurons was decreased (P<0.01), whereas the number of apoptotic neurons was increased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were significantly increased (P<0.01). Compared with the model group, the escape latency of each EA group was significantly shortened; the number of crossing the original platform was significantly increased (P<0.01); the damage of hippocampal neurons was alleviated, the number of surviving neurons was increased (P<0.01), and the number of apoptotic neurons was decreased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were decreased (P<0.01). The results in the 2 Hz EA group and the 2 Hz/100 Hz EA group were superior to those in the 100 Hz EA group. Conclusion: EA with the three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) can improve the learning and memory performances in VD rats subjected to ischemia-reperfusion, its mechanism may be related to the inhibition of neuronal apoptosis and the regulation of the related protein expression of JNK signaling pathway, and the intervention effects of EA with 2 Hz and 2 Hz/100 Hz are more significant.

RESUMEN
Autophagy is a process of degrading the damaged organelles and macromolecules by lysosomes in cells, which belongs to the programmed cell death. Cerebral ischemia is one of the important reasons for activation of autophagy. Studies have showed that autophagy plays a protective role in neuronal death induced by ischemia. However, it has also been found that excessive activation of autophagy could aggravate cerebral ischemia injury. In recent years, more and more Chinese medicine has been proved to regulate the autophagy level of brain neurons and reduce cerebral ischemia injury. In this paper, the main molecular mechanism of autophagy in the process of cerebral ischemic injury and the intervention effects of Chinese herbs on autophagy arereviewed in order to explore the basic principle of regulating autophagy by Chinese herbs and to play a better role in the clinical treatment of cerebral ischemic diseases.

RESUMEN
Objective To explore the effects of seven-step complex decongestion therapy (CDT) on post-operative upper limb lymphede-ma of breast cancer. Methods From August, 2015 to September, 2016, 71 patients with upper limb lymphedema after breast cancer surgery accepted CDT for 20 days, including skin care, opening of lymphatic pathway, relief of scar tissue, manual lymphatic drainage, bandage compression, air pressure wave therapy and functional exercise. The circumference of eight sites of both limbs was measured and the differ-ences were calculated before treatment, and one, five, ten, fifteen and twenty days of the treatment. Results The differences of circumfer-ence increased one to 15 days of the treatment (Z>2.03, P<0.05), and decreased 20 days of the treatment (Z=3.01, P<0.01). Conclusion CDT is effective on lymphedema after breast cancer surgery for 20 days of a course, but may worsen in the first 15 days, which may be relat-ed to acute stress response or redistribution of lymph.

Objective To investigate the anti-fibrotic effects of curcumin in trinitrobenzene sulphonic acid (TNBS) induced intestinal fibrosis in rats and its mechanism. Methods Forty SD rats were randomly divided into model group, treatment group, control group and normal group with 10each. Except the normal group, the other three groups were given 10, 15, 20, 25 and 30 mg of TNBS enema on the 1st, 8 th, 15th, 22nd and 29th days,respectively. The rats in treatment group were intraperitonealy injected with 30 mg/kg of curcumin daily. Control group was injected with 0. 9%NaCl solution and normal group received an equal volume of 50% ethanol enema without any treatment. The damage and fibrosis of colon were detected with HE staining and Masson collagen staining, respectively. The contents of interleukin (IL) -2, tumor necrosis factor (TNF) -α, IL-4 and IL-17 in colon were measured by enzyme-link immunosorbent analysis (ELISA). The expressions of intestinal fibrosis related cytokines such as transforming growth factor (TGF) -β1, connective tissue growth factor (CTGF), Smad3, collagen Ⅰ and collagen Ⅲ mRNA were determined by FQ-PCR.Results The macroscopic and micrpscopic colonic damage scores and collagen area were significantly higher in model group (6.14 ± 1.07, 8. 42 ± 1.40 and 36. 59% ± 4.07%, respectively) and control group (6.17 ± 1.47, 8. 17 ±1.47 and 37.18 %±4.05 %, respectively) than those in normal group (2.13±0.64, 2.25±1.28 and 25.43%±5.39% ,respectively)(P＜0.05). Contents of IL2, TNF-α, IL-17, as well as expressions of intestinal fibrosis related cytokines including TGF-β1, CTGF,Smad3, collagen Ⅰ and Ⅲ mRNA were also higher in model group [(378. 25±29. 90) ng/L,(87.11±23.85) ng/L, (47.80±5.62) ng/L, 4.71%±2.71%,10.33%±6.99%,9.35%±7.32%,1.52% ± 1.11% and 3.04% ±1.33%, respectively] and control group [(410. 06 ± 64.74) ng/L,(100.41±12.59) ng/L, (41.45±2. 12) ng/L, 4. 12%±3.01%,11.46%±4.72%,10. 11%±3.80%,1. 57% ± 1. 35% and 3. 03% ± 3. 53%, respectively] in comparision with normal group [(179.74±20. 73) ng/L, (35. 47±7. 13) ng/L, (14. 48±7. 52) ng/L and 0. 90%± 1. 13%,0.53%±0.47%, 0. 62%±0. 44%, 0. 16%±0. 09% and 0. 18%±0. 10%, respectively] (P＜0.05). While in treatment group, the macroscopic (4.00 ± 1.07 ) and micrpscopic (5. 13 ± 1.46)colonic damage scores, collagen area (30.01%±7.56%), contents of IL-2 [(223.91±28.04) ng/L],TNF-α [(44.19±4. 77) ng/L] and IL-17 [(14.89±4. 31) ng/L], expressions of TGF-β1 (0.85%±0.76%), CTGF (1.56%±1.13%), Smad3 (3.62%±3.03%), collagen Ⅰ (0.40%±0.31%) and Ⅲ (0.60 % ± 1.02 % ) mRNA were much lower than those in model group and control group (P＜0.05 ), but similar to those in normal group (P＞ 0.05 ). Conclusions Curcumin can inhibit intestinal fibrosis caused by excessive "wound-healing" reaction via reducing the overexpression of cytokines in colonic mucosa and attenuating the inflammation of colon.

RESUMEN
Objective To discuss the clinicopathologic features, diagnosis and treatment of pri-mary prostatic signet ring cell carcinoma (PPSRCC). Methods Clinical data of 23 PPSRCC cases were retrospectively reviewed. The mean age was 74 years and majority of them had aggravated dysu-ria. The mean serum PSA was 45.3 ng/ml (7.4-126.8 ng/ml). To exclude the metastasis from stomach and colon SRCC, upper gastric tract endoscopy and barium enema were carried out. Seven pa-tients received radical prostatectomies and 2 patients who had positive margins received hormonal and radiation therapy. The rest of patients received maximal androgen blockade therapy. Photoselective vaporization of the prostate was performed on 11 patients who had lower urinary tract symptoms. All cases were investigated by routine pathological, immunohistochemical studies. Results Seventeen cases of PPSRCC were associated with concurrent high-grade prostatic carcinoma, only 6 cases were pure SRCC. Immunohistochemical stains were positive in all cases for PSA and PAP. Stains were ne-gative for AB/PAS (23/23) and CEA (21/23). The clinical TNM stages were 7 of Ⅱ , 10 of Ⅲ and 6 of Ⅳ. Follow-up was available on 20 cases with a mean 24 months and 3 cases were lost during follow up. Eight cases died of metastasis. Five cases had evidence of recurrence 12-21 months from presen-tation. Conclusions The diagnosis of PPSRCC depends on pathological and immunohistochemical studys after metastasis from stomach and colon SRCC is excluded. Early diagnosis and combination treatment for PPSRCC might improve its prognosis.
