Objective To investigate the effects of acupuncture on ovary morphology and function in dehydroepiandrosterone(DHEA)-induced polycystic ovary syndrome(PCOS)model *** A total of 40 adult female Wistar rats were randomly allocated to 4 groups by a random number table,including control,model,metformin and acupuncture groups,10 rats in each *** rat model was developed by injecting with DHEA(6 mg/100 g body weight)in 0.2 mL of oil *** stimulation(2 Hz,3 mA)was applied to Guanyuan(CV 4),Zigong(EX-CA1)and Qihai(CV 6)acupoints for 30 min daily in the acupuncture group,and metformin(200 mg/kg)was given to rats in the metformin group,both once per day for 21 consecutive days,and rats in the normal group was fed with normal saline and fed *** 21 days of administration,the rat blood samples were collected for detecting the reproductive hormonal levels[luteinizing hormone(LH),follicle stimulating hormone(FSH),estradiol(E2),progesterone(P),testosterone(T)]and inflammatory factors(visfatin,IL-6)*** tissue was used for histopathological *** Compared with the model group,rats in the acupuncture and metformin groups were significantly lower in weight gain,FSH,LH and T levels,and E2 and P levels significantly increased(alll P0.05).Ovarian diameter in the acupuncture and metformin groups were smaller than the model group(P0.05).Conclusion Acupuncture might improve ovary morphology

An image secure transmission scheme combining symbol scrambling and chaotic Wahsh-Hardmard precoding is proposed in orthogonal frequency division multiplexing(OFDM)-based visible light communication(VLC) *** the proposed scheme, a two-dimensional(2 D) logistic-sine-coupling map(LSCM) is employed to generate two chaotic sequences. One is used to scramble the 16 quadrature amplitude modulation(QAM) symbols, and the other is used to scramble the rows of standard Walsh-Hadamard transform(WHT). The simulation results show that the proposed scheme can not only reduce the peak-average-power ratio(PAPR) but also achieve the image secure transmission over OFDM-based VLC systems.

Solubilities of ternary systems Li+,K+/SO42--H2O (1) and Li+,Mg2+/SO42-H2O (2) were investigated by isothermal method at 25℃. Physico-chemical properties of solutions, such as density, refractive index, viscosity, conductivity and pH, were determined. Phase diagram of the system (1) consists of three solubility branches and three crystallization fields corresponding to K2SO4, Li2SO4.H2O and LiKSO4. LiKSO4 is an incongruent compound, and its transition point is estimated graphically to be 45.5-46.0℃. No solid solution of LiKSO4 with Li2SO4.H2O was found in the system. The system (2) is a simple eutonic type. Pitzer model of electrolyte solution was used to check the obtained solubilities. Data comparison gives good agreement. Two equations were used to correlate density, refractive index of the solution with its composition. Differences between measured and calculated values are less than 0.6% for density, 0.15% for the latter.

V-BLAST接收机是提高无线通信系统传输数率的有效技术,但由于该算法存在大量的求伪逆、迫零和排序,算法的复杂度高,限制了它在实际中的应用;线性迫零(ZF)接收机和最小均方误差(MMSE)接收机复杂度低, 但性能差。该文提出了一种分组检测空时接收机,组内采用串行干扰抵消接收,与V-BLAST接收机相比,降低了算法的复杂度。仿真结果表明:所提出的基于MMSE准则下的分组检测空时接收机的性能明显好于基于迫零准则的V-BLAST接收机。

　　β-Substituted enones have been considered less reactive in Baylis-Hillman reaction. The reaction of cyclicenones is sluggish or does not occur at all under traditional conditions. [1] Therefore, substituted cyclic enones havebeen less explored in Baylis-Hillman reaction due to the extremely low reactivity. In this communication, we reported Baylis-Hillman reaction of substituted cyclic enones using our previously developed conditions with imidazole as catalyst. The reaction proceeded smoothly in aqueous media affording the desired product with good yields and moderate diastereoselectivity.……

　　β-Substituted enones have been considered less reactive in Baylis-Hillman reaction. The reaction of cyclic enones is sluggish or does not occur at all under traditional conditions. Various catalysts have been developed to pro mote the reaction of cyclic enones but with limited success. In previous study, we found that imidazole can catalyze the Baylis-Hillman reaction involving cyclic enones in aqueous THF solution. [1] In our continued efforts, a variety of azole compounds were examined in Baylis-Hillman reaction. We found that the azoles act as effective catalysts in properly adjusted water solution.……
