Objective To investigate the effects of Shouwu-Yizhi capsule on learning and memory, and the expressions of presenilin 1(PS1),β-amyloid precursor protein (APP) mRNAs in the hippocampus following cerebral ischemia reperfusion in rats. Methods Sprague–Dawley rats were randomly divided into a Shouwu-Yizhi group, a piracetam group, a model group, and a sham operation group with 20 rats in each group. Focal cerebral ischemia reperfusion model was induced by middle cerebral artery occlusion for 2 hours. Seven days after ischemia reperfusion, the rats in the Shouwu-Yizhi and piracetam groups were administered intragastrically Shouwu-Yizhi solution (52 mg/ml) and piracetam solution (28 mg/ml) for 28 days, both in dose of 1 ml/(100 g?d) for 28 days;and the rats in the model and sham operation groups were given intragastrically equivalent volumes of normal saline. Learning and memory were tested using the Morris water maze, and the expressions of PS1 and APP mRNAs were measured using real-time quantitative fluorescent PCR. Results Water maze test showed that the escape latency (12.98±0.70s vs. 9.43±0.78s) was significantly shorter, and the frequency of crossing platform (5.08±0.39 vs. 7.62±0.43) significantly lower in the model groupthan those in the sham operation group; the escape latency (9.77±0.58s vs. 12.98±0.70s) was significantly shorter and the frequency of crossing platform (7.40±0.44 vs. 5.08±0.39) significantly lower in the Shouwu-Yizhi group than those in the model group(all P<0.01). The expressions of PS1 (0.99±0.01 vs. 1.08± 0.03)and APP (1.06±0.03 vs. 1.12±0.04) mRNAs in the hippocampus in the Shouwu-Yizhi group were significantly decreased than those in the model group (P<0.05 or 0.01). Conclusion Shouwu-Yizhi capsule may inhibit the expressions of PS1 and APP mRNAs in the hippocampus, and improve the learning and memory following cerebral ischemia reperfusion in rats.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

OBJECTIVETo investigate the role of fibroblasts in reconstruction of composite skin, and evaluate the effect of composite skin on full-thickness skin defect.
METHODSKeratinocytes and fibroblasts were seeded on the surface of acellular dermal matrix and cultivated in vitro to reconstruct the composite skin. Adherence of keratinocytes to dermal matrix was observed. Then take rate and histological construction were investigated after the composite skin was used to cover full-thickness skin defect wound in nude mice (n = 16).
RESULTSKeratinocytes grew and proliferated to reach tho confluence on the surface of the acellular dermal matrix. Keratinocytes adhered more stablely and could not be torn down from dermal matrix in operation when few fibroblasts were seeded on the epidermal surface of the dermal matrix. After grafting, the composite skin closed the full-thickness wound in nude mouse. The total survival was achived in 10 mice (62.5%). The newly generated skin was with intact histological construction of base membrance containing laminin and type IV collagen.
CONCLUSIONComposite skin could close the full-thickness wound, and fibroblasts could improve adherence of keratinocytes to dermal matrix, which should benefit the survival of composite skin.

Objective:To explore the effect of prospective nursing oriented to hypothermia prevention on the recovery of consciousness and stress response of general anesthesia patients in the Operating Room.Methods:The convenience sampling was used to select 120 surgical patients undergoing general anesthesia in Shanxi Provincial People's Hospital from June 2019 to December 2020. According to the operation time, the patients were divided into the control group and the observation group, each with 60 cases. The control group conducted conventional heat-preservation nursing, and the observation group carried out prospective nursing oriented to hypothermia prevention. The differences in perioperative stress indicators, recovery quality, and adverse reactions of anesthesia were compared between the two groups.Results:There was no significant difference in serum cortisol (COR) and norepinephrine (NE) before anesthesia and 12 hours after operation between the two groups ( P>0.05) . Serum COR and NE in the observation group were lower than those in the control group 30 minutes after the operation and 10 minutes after extubation, and the differences were statistically significant ( P<0.05) . The observation group's spontaneous breathing, recovery of consciousness, catheter removal, and Post-Anesthesia Care Unit (PACU) retention time were shorter than those of the control group, and the differences were statistically significant ( P<0.05) . The total incidence of adverse reactions of anesthesia in the observation group was lower than that in the control group also with a statistical difference ( P<0.05) . Conclusions:Prospective nursing oriented to hypothermia prevention can reduce the perioperative stress response of general anesthesia patients in the Operating Room, improve the quality of consciousness recovery, and reduce the adverse reactions of anesthesia.

OBJECTIVEThe aim of this study was to establish a standard protocol for detection of EGFR mutations in cytologic specimens.
METHODS287 cytologic samples were collected from the patients who were suspected of having lung cancer at six hospitals in Beijing. A detection protocol for EGFR mutations was designed. Two comparative experiments were carried out for the coincidence in EGFR mutation rates between direct sequencing (Seq) and amplification refractory mutation system (ARMS) methods, and between 40 matched cytologic samples with formaldehyde-fixed paraffin embedded (FFPE) cytologic blocks and cytospin slides.
RESULTSTumor cells were found in 236 out of 287 cases (82.2%, 236/287) . Among them, there were 31 cases (13.1%, 31/236) of low tumor cell content samples and 205 cases (86.9%, 205/236) of high tumor cell content samples. 180 cases in the high tumor cell content samples (87.8%, 180/205) were diagnosed to be consistent with NSCLC. 25 out of 194 cases were ruled out or indefinite to be diagnosed as NSCLC by immunohistochemistry. By direct sequencing, the mutation rate of EGFR was 27.8% (50/180) in NSCLC samples and 28.2% (50/177) in adenocarcinoma samples (high tumor content samples) . By ARMS, the mutation rate of EGFR was 45.6% (82/180) in NSCLC samples and 46.3% (82/177) in adenocarcinoma samples (high tumor content samples). The EGFR mutation rate in low tumor content samples was 38.7% (12/31) , there was no significant difference in EGFR mutation rates between the groups of low tumor cell content samples and high tumor cell content samples (P = 0.12). The concordance rate of EGFR mutation rates was 100% between scraping tumor cells from slides samples and from FFEP blocks in the 40 matched samples. Forty-eight out of 180 definitive NSCLC patients received Gefitinib therapy. The FPS was 12 months in the gefitinib-treated ARMS⁺ group and 2 months in the ARMS⁻ group (P < 0.001), and the OS was 19 months in the gefitinib-treated ARMS⁺ group and 7 months in the ARMS⁻ group (P = 0.003), but no significant differences were found in the efficacy (PFS and OS) of Gefitinib between Seq⁺ and Seq⁻ groups (P = 0.227, P = 0.510, respectively), and Seq⁺/ARMS⁺ and Seq⁻/ARMS⁺ groups (P = 0.354, P = 0.334, respectively).
CONCLUSIONSThe detection protocol for EGFR mutations in cytological specimens introduced in this study is tested to be reliable and feasible. Pathological evaluation and immunohistochemistry are important in the detection procedure of EGFR mutations in cytologic specimens. High sensitivity methods should be selected for detection of EGFR mutations in cytologic samples.
