Objective To investigate the effect of endoplasmic reticulum stress (ERS)-associated apoptosis on renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO) in rats. Methods Eighteen healthy male Wistar rats undergoing UUO were sacrificed at 3,7,14 days after operation. Additional seven rats underwent sham operation. Histological changes were observed by HE and Masson staining. Immunohistochemistry was performed on renal tissue for α-smooth muscle actin (α-SMA). Chromatometry was used to detect the content of hydroxyproline. Apoptosis cells were determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and the electrophoresis analysis of genome DNA. The mRNA expression of glucose-regulated protein 78 (GRP78), which are important markers of ERS, were detected by RT-PCR. Western blotting was used to assess the protein level of GRP78 and cysteinyl aspartate specific proteinase-3 (caspase-3). Results Compared with sham operation group, the degree of renal interstitial and the level of hydroxyproline content of UUO group increased significantly (P<0.05). Immunohistochemistry staining indicated that a-SMA extensively expressed in renal tubular and interstitial cells. The apoptotic cells in the renal tubular and interstitium were continuously increased from day 3 to the end of experiment of UUO group. As early as 3 days after surgery, the mRNA level of GRP78 in UUO group increased compared with sham operation group (P<0.01), while the protein expression increased on day 7 after surgery (P<0.01). Prolonged ERS triggered apoptosis, the protein expression of caspase-3 increased significantly on day 3 after surgery (P< 0.05), and the expression sustained high level during the experiment afterwards. There was a positive correlation between GRP78 protein expression and hydroxyproline content (r =0.657, P< 0.01) as well as caspase-3 protein expression (r=0.714, P<0.01). Conclusions UUO induces a significant up-regulation in endoplasmic reticulum molecular chaperones at early stage, indicating that ERS response is activated in the rat kidney. Prolonged ERS can lead to renal tubular and interstitial cell apoptosis, and caspase-3-mediated ERS associated apoptosis may contribute to the fibrosis.

Objective To investigate the effect of acupuncture at point Neiguan on mouse myocardial hypertrophy.Methods Thirty-sixty healthy C57BL6 mice were randomized into blank, model and treatment groups, 12 rats each. In the treatment group, an acupuncture needle was inserted into point Neiguan and retained for 15 min, once daily. After nine days of treatment, the ratios of cardiac weight/tibial length were compared between the groups. Left ventricular myocardial tissues were processed by Masson trichrome staining in every group of mice. The differences in myocardial fiber arrangement and collagen fiber distribution between the groups were observed under the ordinary optical microscope in 100 times of field of vision. Sarcomere structure, myofibril arrangement, collagen fibers and mitochondria in injured myocardial tissues were observed by transmission electron microscopy. Results Heart rate increased significantly in the model group and decreased significantly in the acupuncture group compared with the blank group. Cardiac weight and the ratios of cardiac weight/tibial length increased significantly in the model and acupuncture groups compared with the blank group (P<0.01) and decreased significantly in the acupuncture group compared with the model group (P<0.01). In the model group, myocardial tissues had compensatory hypertrophy with incontinuous status, and myocardial transverse striations had severe disorder/disruption, karyopyknosis appeared and cytoplasmic eosinophilic change became obvious in few of the rats. The results were better in the acupuncture group than in the model group. In the model group, part of myofibrils had focal fusion, interstitial collagen fibers proliferated and mitochondria had swelling and compensatory increase. The results were also better in the acupuncture group than in the model group.Conclusions Acupuncture at point Neiguan can reduce the production of collagen fibers and mitochondria, improve the arrangement of sarcomere structure and delay the progression of myocardial hypertrophy.

Multiple myeloma is common in the older population and is treated mainly with chemotherapy. However, chemotherapy-related side effects imitate the clinical manifestations of Sheehan's syndrome, which leads to misdiagnosis and missed diagnosis, particularly for older patients without a clear history of postpartum hemorrhage. Therefore, when older women with malignant myelomas show refractory hyponatremia and gastrointestinal disorders while under chemotherapy, a diagnosis of Sheehan's syndrome should be considered. The early detection of the disorder will guarantee timely individualized treatment.
