OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

In this study, the psbA-trnH sequence as DNA barcode was used to evaluate the accuracy and stability for identification pteridophyte medicinal material Pyrrosiae Foliumas from adulterants. Genomic DNA from 106 samples were extracted successfully. The Kimura 2-Parameter (K2P) distances and ML tree were calculated using software MEGA 6.0. The intra-specific genetic distances of 3 original plants were lower than inter-specific genetic distances of adulterants. The ML tree indicated that Pyrrosiae Folium can be distinguished from its adulterants obviously. Therefore, the psbA-trnH sequence as a barcode of the pteridophyte, can accurately and stably distinguish Pyrrosiae Folium from its adulterants.

Objective To investigate the effect of local injection of Botulinum toxin type A(BTXA) on spasticity and function of the affected upper limb in stroke patients.Methods A total of 32 stroke patients were re- cruited and randomly divided into two groups:a BTXA group and a control group.All the patients had spasticity of upper limb muscles,which scored grade 2 to 3 with the Modified Ashworth Scale(MAS) ,and decreased elbow joint range of motion.The 16 patients in the BTXA group received BTXA injection in the biceps brachii muscles and flexor muscles of forearm on 10～15 points,while those in the control group did not.All the patients in both groups were treated with rehabilitation training techniques.The MAS,Fugl-Meyer upper limb function assessment and Barthel In- dex were employed to evaluate the changes of muscle tone,upper limb function and activity of living (ADL)perform- ance of the patients before injection and at 1st,2nd,6th 12th weeks after injection.Results The therapeutic effect between the BTXA group anti control group was significantly different in terms of biceps muscle tone,the scores of Fugl-Meyer upper limb function assessment and Barthel Index.Compared with preinjection,muscle tone was de- creased significantly and ADL performance was improved after injection in BTXA group.The effects of BTXA lasted more than 12 weeks.Conclusion Intramuscular muhipoint injection of BTXA was useful in reducing muscle spas- ticity,and was helpful for increasing motor ability of the affected upper limb and ADL performance of the stroke pa- tients.

Although the essential oil of Xiangfu Siwu decoction (XFSWD) has strong pharmacological activity, its special physical and chemical properties restrict the clinical application and curative effect. In this paper, Xiangfu Siwu decoction essential oil (XFS-WO) was prepared by forming inclusion complex with β-cyclodextrin (β-CD). The present study is to investigate the effect of β-CD inclusion complex on the transport of major components of XFSWO using Caco-2 cell monolayer model, thus to research the effect of this formation on the absorption of drugs with low solubility and high permeability, which belong to class 2 in biopharmaceutics classification system. A sensitive and rapid UPLC-MS/MS method was developed for simultaneous quantification of senkyunolide A, 3-n-butylphthalide, Z-ligustilide, dehydrocostus lactone and α-cyperone, which are active compounds in XFSWO. The transport parameters were analyzed and compared in free oil and its β-CD inclusion complex. The result revealed that the formation of XFSWO/β-CD inclusion complex has significantly increased the transportation and absorption of major active ingredients than free oil. Accordingly, it can be speculated that cyclodextrin inclusion complex can improve bioavailability of poorly water-soluble drugs. Above all these mentioned researches, it provided foundation and basis for physiological disposition and pharmaceutical study of XFSWD.

OBJECTIVETo observe the effect of Xueyou Mixture (, XYM) on blood coagulation factors and its safety in treating hemophilia.

METHODSTo the randomly selected 65 inpatients of hemophilia, XYM was administered accompanied with intravenous dripping of liver cell growth factor 60-100 mg once a day to protect the liver, with no blood products like concentrated VIII and FIX factors or blood plasma given. The treatment lasted for 3 weeks. The short-term efficacy and adverse reactions were observed. The long-term efficacy in patients was observed in a follow-up study of 6-12 months after they were discharged from the hospital but continuously took XYM orally.

RESULTSThe short-term markedly effective rate in the patients was 95.38% (62/65). After they were treated for 3 weeks, the level of FVIII factor activity increased in 56 patients of type A from (3.32+/-2.21) % to (4.18+/-2.23) %, and in 9 of type B from (4.92+/-1.81) % to (5.64+/-1.96) %. Compared with that before treatment, the difference was significant in both of them (P<0.01). No obvious adverse reaction was found in the treatment period. The follow-up study showed that in 22 patients of type A, the FVIII factor activity ratio increased from (3.25+/-2.11) % to (6.31+/-2.16) %, (8.36+/-1.05) %, and (16.38+/-2.71) % in the 2nd, 3rd and 6th month after discharge respectively, all showing significant difference to that before treatment (P<0.01); and in 4 patients of type B, it increased from (4.15+/-2.26) % to 7.8% and 11.6% (mean value) in the 2nd and 6th month respectively.

CONCLUSIONXYM could raise the activity of factors VIII and IX in patients with hemophilia, and the degree of the rise is related with the duration of the therapy, with no obvious adverse reaction, which strikes out a new path and new train of thinking for the treatment of the disease by nonblood preparation.

OBJECTIVETo explore targets of Chinese herbal medicine at cellular and molecular leve1s through an experimental study on Yinxingye Capsule (YC) intervening vascular endothelial cell apoptoeis of hyperhornocysteinemia (HHcy) rats.

METHODSThe HHcy model was prepared in male Wistar rats. Totally 42 rats were randomly divided into 4 groups, i.e., the control group (n =10), the model group (n = 11), the YC group (n =11), the folic acid group (n =10). Carboxy methyl cellulose (CMC) solution (1%) was administered to rats in the control group by gastrogavage.3% methionine suspension at 1. 5 g/kg was administered to rats in the model group by gastrogavage. 3% methionine suspension at 1. 5 g/kg and folic acid suspension at 0. 06 g/kg was administered to rats in the folic acid group by gastrogavage. 3% methionine suspension at 1. 5 g/kg and YC at 0. 02 g/kg was administered to rats in the YC group by gastrogavage. Morphological changes of aortic tissue were observed by hematoxylin eosin (HE) staining. The plasma homocysteine (Hcy) level was detected in each group. The endothelium-dependent diastolic functions of the thoracic aorta on different concentrations of sodium nitroprusside (SNP) and acetylcholine (Ach) were detected. Gene expressions of Bcl-2-associated X protein (BAX), inducible nitric oxide synthase (iNOS), c-Fos, cellular inhibitor of apoptosis protein 2 (c-IAP2) were detected by real time polymerase chain reaction (RT-PCR).

RESULTSPathological results showed that thickening aortic endothelium, swollen and desquamated endothelial cells. Few foam cells could be seen in the model group. Myoma-like proliferation of smooth muscle cells in tunica media could also be seen. These pathological changes were milder in the YC group and the folic acid group. Compared with the control group, plasma Hcy levels increased in the model group (P <0. 05). The endothelium-dependent diastolic rates at 10(-6) and 10(-4)mol/L Ach and 10(-7) -10(-3)mol/L SNP all decreased in the model group (P <0. 01, P <0. 05). Gene expressions of Bax, c-Fos, and iNOS increased, but c-IAP2 gene expressions decreased in the model group (all P <0. 05). Compared with the model group, plasma Hcy levels decreased in the YC group and the folic acid group (P <0. 05). The endothelium-dependent diastolic rates increased in the YC group and the folic acid group at various SNP concentrations except 10(-6) mol/L SNP in the folic acid group. The endothelium-dependent diastolic rates increased in the YC group and the folic acid group at 10(-6) and 10(-4)mol/L Ach (all P <0. 05). Gene expressions of Bax, c-Fos, and iNOS decreased in the YC group and the folic acid group, but c-IAP2 gene expression increased in the folic acid group (all P <0. 05).

CONCLUSIONYC could reduce plasma Hcy levels, down-regulate gene expressions of Bax, c-Fos, and iNOS, thereby reducing apoptosis of vascular endothelial cells, improving vascular endothelial function, and delaying atherosclerotic process.
