Abstract
It is difficult to distinguish between H2O and D2O due to their very similar properties. Triphenylimidazole derivatives with carboxyl groups (TPI-COOH-2R) show intramolecular charge transfer that responds to polarities and pH of solvents. Here, a series of TPI-COOH-2R with very high photoluminescence quantum yields (73-98%) were synthesized to distinguish D2O from H2O by the method of wavelength-changeable fluorescence. In a mixed THF/water solution, the increase of H2O and D2O contents will separately induce different pendulum-type fluorescence variations and form plots of closed circles with the same starting and ending points from which a THF/water ratio that displays the most different emission wavelengths (up to 53 nm with an LOD of 0.064 vol %) can be determined to further distinguish D2O from H2O. This is proved to be originated from the various Lewis acidities between H2O and D2O. The results of theoretical calculations and experiments suggest that, for different substituent groups in TPI-COOH-2R, an appropriate electron-donating effect is beneficial to distinguish between H2O and D2O, while the electron-pulling effect is adverse. Moreover, because the potential hydrogen/deuterium exchange does not affect the as-responsive fluorescence, this method is reliable. And this work provides a new strategy for the design of fluorescent probes for D2O.

Abstract
Flexible photodetector shows great potential applications in intelligent wearable devices, health monitoring, and biological sensing. In this work, single crystal β-tellurium nanowires were grown on flexible muscovite by molecular beam epitaxy, constructing high-density ordered nanomesh structure. The prepared photodetectors based on tellurium nanomesh exhibit excellent mechanical flexibility, fast response in a broad range from ultraviolet to near-infrared, and good photosensitivity. We found that the flexible photodetectors with Shottky contact drastically suppressed dark current, while the response speed was lowered in comparison to the devices with ohmic contact, as holes would take a long time to tunnel through the Shottky barrier between metal and p-type Te. Moreover, the photoresponse of flexible Shottky photodetectors can be modulated by piezoelectricity of tellurium, and pronounced photocurrent increase after bending many times. Under external stress, polarization charges could tune Shottky barrier height of the metal/tellurium, resulting in variation of photocurrent. This research not only explores the broadband photoresponse and piezoelectric effect of tellurium nanomesh, but also promotes the integration and development of broadband flexible optoelectronic devices.

Abstract
Objective: To study the changes of gonadotropin releasing hormone agonist (GnRH-a) in pinopodes during luteal phase and to explore the possible mechanism of GnRH-a in luteal phase support of assisted reproductive technology (ART). Methods: Totally 40 primary infertility women who were treated with ART due to male factors were enrolled, according to the order of the group they were randomly divided into experimental group and control group. On the 7th day after ovulation, the experimental group received a subcutaneous injection of 0.1 mg of GnRH-a, while the control group received a subcutaneous injection of placebo only (0.9% saline 2 ml), 3 days later they came to the clinic again. Serum estradiol and progesterone levels were measured before and after treatment in each group. Pinopodes were collected for electron microscopic examination. Levels of ER and PR were detected by western blot. Results: (1) There was no significant difference between the experimental group and the control group in the estrogen level before and after the treatment (all P>0.05). The level of progesterone in the experimental group after treatment [(66.8±14.9) nmol/L] was significantly higher than that before treatment(P<0.05); also significantly higher than the same period of the control group (P<0.05). (2) There was no significant difference in the expression of ER protein in the experimental group before and after treatment (P>0.05). The expression of PR in the experimental group after treatment was significantly lower than that before treatment (P<0.05); also lower than the same period of the control group (P<0.05). (3) Expression amount of pinopodes in the experimental group after treatment was significantly higher than that before treatment [65% (13/20) versus 25% (5/20), P<0.05], and the development trend was more mature [the percentage of maturation:75% (15/20) versus 35% (7/20), P<0.05]. Expression amount of pinopodes after treatment and the percentage of maturation in the experimental group were significantly higher than those in the same period of control group (P<0.05). Conclusion: GnRH-a in luteal phase support may play a role through the corpus luteum, which may promote the secretion of progesterone, downregulation of PR expression, promote the growth of pinopodes, and improve the endometrial receptivity.

Abstract
Antibody-mediated rejection (AMR) is an important factor affecting survival after renal transplantation. A highly selective proteasome inhibitor, bortezomib, clears activated plasma cells from the body and has important therapeutic effect on AMR. We investigated the effects of bortezomib on AMR in a patient after a second renal transplant. Biopsy confirmed the diagnosis of mixed cellular rejection and AMR. Bortezomib was administered on day 1 (1.3 mg/m(2)), day 4 (1.0 mg/m(2)), and day 8 (1.0 mg/m(2)). On the same days, 250 mg methylprednisolone was administered once, and cyclosporine dose (5 mg·kg(-1)·day(-1)) was reduced by 50%. Oral mycophenolate mofetil and steroid were withdrawn on day 1 of bortezomib treatment. Intermittent double-filtration plasmapheresis was also performed. We monitored parameters, including T lymphocyte subsets, CD139 and CD19 expression, panel reactive antibody (PRA), and serum creatinine concentration. At follow-up 6 months after bortezomib treatment, we observed: 1) serum creatinine stabilized at 130 μM from a peak level of 337 μM; 2) PRA decreased from a maximum of 66.7 to 0%; 3) blood plasma cell percentage rebounded after significantly decreasing following the first dose of bortezomib; 4) in renal allograft biopsy, immunohistochemical staining for C4d shifted from strongly positive to negative, and cellular rejection shifted from type IIA to borderline; and 5) adverse effects such as platelet suppression, hypotension, and grade 3 peripheral neuropathy emerged. Bortezomib effectively treated antibody-mediated renal transplantation rejection in this case study, but clinical trials with large sample sizes are still needed to explore clinical safety and tolerability.

Abstract
BACKGROUND The blood vessels of a transplanted organ are an interface between the donor and the recipient. The endothelium is believed to be a major target for graft rejection. After transplantation endothelial cells of a transplanted organ may be of recipient origin. OBJECTIVES In this study we sought to determine whether endothelial chimerism correlates with graft rejection. METHODS Biopsy samples from 34 renal transplants of female recipients who received kidneys from male donors were studied for the presence of endothelial cells of recipient origin. Formalin-fixed, paraffin-embedded tissue sections of renal biopsy samples were examined by fluorescence in situ hybridization (FISH) for the presence of endothelial cells containing two X chromosomes, using a biotinylated Y-chromosome probe and digoxigenin-labeled X-chromosome probe. RESULTS The FISH methods identified endothelial cells of recipient origin. Endothelial chimerism was common, irrespective of rejection. Its presence was focal with these elements, coexisting in the biopsy. CONCLUSIONS We observed no correlation between the percentage of recipient endothelial cells among vascular elements and the type of graft rejection (P > .05).

Abstract
OBJECTIVE To probe into the effect of Huancongdan capsule (HCDC) on the vascular dementia (VD) related factors, including lipoprotein, apolipoprotein (apo) and serum immunoglobulin. METHODS Fifty-two patients of VD were divided into the HCDC group (27 patients, treated with HCDC) and the control group (25 patients, treated with Naofukang). Changes of related parameters were observed. RESULTS The effects in lowering triglyceride and total cholesterol and elevating high density lipoprotein cholesterol in the HCDC group were superior to those in the control group (P < 0.01 or P < 0.05), but the effect in lowering low density lipoprotein cholesterol was similar in the two groups (P > 0.05). Compared with data before treatment, in the HCDC group after treatment, the levels of serum apoA1 increased, and serum apoB100, IgA, IgG and circulating immune complex decreased significantly (P < 0.05 or P < 0.01), but the change of apoE level was insignificant (P > 0.05). CONCLUSION Through adjusting lipid metabolism, HCDC could improve blood rheologic characteristics, promote cerebral blood flow, improve the oxygen carrying capacity of blood to prevent and treat VD. One of its mechanisms is increasing apoA1 and decreasing apoB100 levels, preventing and improving atherosclerosis and reducing damage of vascular endothelial cells, the another may be its action in improving immune function.

Abstract
The coding region cDNA sequence of rat neuroglobin (NGB) was obtained by RT-PCR technique using a degeneracy PCR primer pair based on previously reported cDNA sequence of human and mouse NGB gene. Result demonstrated that the coding region cDNA sequence of rat NGB gene is 456 bp in length, which could encode a protein of 151 amino acids. The rat NGB gene is highly homology with mouse (96%) and human (88%) NGB gene. However, several polymorphism sites were also detected in the rat NGB coding region: 113 t/c [L38P], 133 a/g [N45D], 388 a/g[R130G], 417 t/c. The cDNA sequence of rat NGB gene has been registered in GenBank under the accession number AF333245. Moreover, highly expression level of rat NGB in brain, liver, kidney, heart and skeletal muscle was detected by using multiple tissue RT-PCR technique, indicating the functional importance of this novel gene.

Abstract
OBJECTIVE To compare the antibody level of vaccine group and control group in a randomized, controlled trial of type B inactivated vaccine against hemorrhagic fever with renal syndrome(HFRS) in Jiande County of Zhejiang Province and to find out if there is enhancement of subclinical infection about type B inactivated vaccine against HFRS. METHODS The number of sera collected (July 1994-July 1998) in vaccine group immunized type B inactivated vaccine against HFRS and control group were 305 and 283 persons in Jiande County respectively, and indirect immunofluorescent antibody method(IFAT) was used for testing the titer of HFRS IgG in sera. The cut-off values were determined on IFA titer of the second sera in control group with positive and negative IFA before vaccine was given respectively, and the subclinical infection of positive and negative IFA of the first sera in vaccine group was evaluated. RESULTS When taking different cut-off values of subclinical infection, there were no statistical differences in HFRS IFA positive rates between vaccine group and control group of positive IFA in the first sera. In vaccine group and control group of negative IFA before vaccine given, also the IFA positive rates were not statistically different in these groups. There were no statistical differences of IFA GMT and IFA sero-negative rate between vaccine group and control group. CONCLUSIONS The investigation showed there was no statistical difference in antibody level between vaccine group and control group, so there could not be enhancement of subclinical infection of vaccine group receiving type B inactivated vaccine against HFRS.

Abstract
The Photoautotrophic cultivation of Synechococcus sp. PCC 7002 in a 15 L-airlift photobioreactor was carried out. The changes of light intensity with cell density and optical length in the cultivation system were investigated. Based on experimental results, the light attenuation could be described by I = I0exp [-(-0.0239 + 0.0777 OD750).L]. The effects of the variations of light intensity, CO2 concentration in gas inlet and culture temperature on the growth of cells during the cultivation process have also been studied. The optimized condition was determined and a high dry cell density of 3.4 g/L was obtained. The volumetric productivity reached 0.57 g/(L.d) under the optimized condition.

Abstract
Conjugates of oligodeoxyribonucleotide phosphorothioate (ODN-PS) with folic acid, retinoic acid, arachidonic acid, and methoxypoly(ethylene glycol)propionic acid have been synthesized. The procedure involved the initial solid-phase preparation of 5'-amino-functionalized ODN-PS using N-pent-4-enoyl-derived (PNT) nucleoside phosphoramidites followed by conjugation of the oligonucleotide either to the ligand acids, using 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide as a coupling reagent, or to their corresponding succinimidyl derivatives. Subsequent exposure of the support to aqueous ammonium hydroxide (28%, 2 h, 55 degrees C) resulted in the release of the fully deprotected ODN conjugates, which were purified by reversed-phase HPLC or by preparative polyacrylamide gel electrophoresis. The identity of the oligonucleotide conjugates was confirmed by MALDI-TOF mass spectral analysis.

OBJECTIVE To assess the effect of Bugu Shengsui capsule (BGSSC) in treating primary osteoporosis. METHODS Using double energy X-ray bone densimeter and radioimmunoassay (RIA), the effect of BGSSC in treating primary osteoporosis (OP) with Kidney-Yang Deficiency syndrome. RESULTS The clinical markedly effective and total effective rates of BGSSC were 46% and 82%, respectively. The rate of TCM group is significantly higher than that of the control group (Vitamin D plus calcium). BGSSC could improve bone mineral density by the verification of double energy X-ray bone dansity (DEXA). It could also increase the level of serum calcitonin, luteinizing hormone and calcium, decrease the activity of parathyroid hormone. CONCLUSIONS The effects of BGSSC on primary OP included increasing patient's bone mineral density, depressing bone resorption and decreasing bone loss.

Abstract
OBJECTIVE To assess the efficacy of Yizhi capsule (YZC) in treating senile dementia. METHODS Sixty-one vascular dementia (VaD) patients were randomly divided into YZC and control groups. There were 32 cases in YZC group, 4 capsules each time three times a day. In control group, there were 29 cases, 2 mg of hydergine were given each time three times a day, single-blind method was used and the treatment course was two months. RESULTS YZC could remarkably increase mini-mental state examination (MMSE) and Hamilton Depression Scale (HDS) marks of VaD patients. YZC had the effect of improving balance and gait ability of VaD patients. YZC could improve the abnormal blood velocity (BV), as well as improve cerebral blood flow, brain electrical activity monitoring (BEAM) and hemorheological indexes especially for the abnormal case. No side-effect or toxic-effect was observed in the administration period. CONCLUSION YZC had certain effect on senile VaD, and it was safe in application.

Abstract
Shuxuening was made of extract of Folium Ginkgo, the Shuxuening tablet No. 2 was a pure extract and No. 1 was a crude extract. Forty-six coronary heart disease patients were divided randomly into two groups according to the ratio of 2:1, Shuxuening tablet No. 1 and No. 2 were given to the two groups respectively. Results showed that both of them could alleviate the symptom of angina, the total effective rate of 2 groups were 60.00% and 83.87%, there was no significant difference between the two groups. But for the angina of middle and severe degree, the total effective rate of No. 2 was 83.33%, while that of No. 1 was 33.33%, the difference was significant (P < 0.01). They could also improve the abnormal electrocardiogram, the total effective rate of two groups were 60.00% and 74.19%, no significant difference between them was found. The two drugs could decrease the blood lipid as well.

Abstract
UNLABELLED Longevity-Antihypertensive-Mixture (LAM) is a Chinese herbal drug, which could tonify Kidney in treating the hypertension with Kidney Deficiency in aged patients. RESULTS 302 patients were randomly divided into three group: The treated group was subdivided into group I (107 Kidney Yin Deficiency patients) and group II (96 non-Kidney Yin Deficiency cases) and group III (99, control group). After treatment of LAM for 8 weeks, the rate of normalizing the blood pressure was 92.52% in group I while in group II, it was 84.43%, the symptoms were also significantly alleviated, and in group III, the rate was 70.71% only. The aorta compliance in group I significantly improved after LAM treatment (P < 0.025), the quality index of left ventricle reduced in treated group, and there was significant difference between treated and control groups. After treatment, LAM could shorten the length of extracorporal thrombus in group. The study showed that LAM could treat hypertension through LAM, administration with good effect.

Abstract
With a home-made jitter data processing board and microcomputer for recording extracellular single fiber action potential (SF-AP), variations of the time intervals of the SF-AP pairs, or the jitters, from two adjacent muscle fibers in the unique motor unit in tibialis' anterior in response to repeated stimuli were measured. The jitter distribution of 936 recorded from 7 rabbits was positively showed with a percentile value of P75-P25 of 54.99-14.61 microseconds. The data suggested that the lower limit was smaller than that of skeletal muscles in normal human and that there exists also some differences in the jitter values of SFEMG between human and rabbit muscles.

Abstract
In the past, surgeons thought that severe presacral hemorrhage during proctectomy was caused by damage of the presacral venous plexus. By studying the anatomy and clinical data, we found that injury of the sacral basivertebral vein also caused this serious complication. Presacral hemorrhage is seen as massive bleeding from the distal pelvic surface of sacrum or from one to several large-caliber foramina of sacral basivertebral veins in that area. This type of presacral hemorrhage is more dangerous than that from simple injury of presacral venous plexus and sometimes it is fatal. We describe the anatomic features of the vertebral venous system and its close relationship with severe presacral hemorrhage. We also propose some new concepts about cause, hemostatic measures, and principles of prevention.
