OBJECTIVETo investigate the correlations of 24 biochemical markers in the seminal plasma with routine semen parameters.

METHODSAccording to the WHO5 standards, we analyzed the routine semen parameters of 66 subfertile men, including the semen volume, sperm concentration, total sperm count, sperm motility, and the percentage of progressively motile sperm (PR). Based on the calibration and quality control measures and using an automatic biochemistry analyzer or electrolyte analyzer, we detected 24 biochemical markers in the seminal plasma of the patients, including total protein (TP), albumin (Alb), globulin (Glb), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), γ-glutamyltransferase (GGT), lactate dehydrogenase (LDH), creatine kinase (CK), alpha hydroxybutyrate dehydrogenase (αHBDH), adenosine deaminase (ADA), glucose (Glu), triglyeride (TG), total cholesterol (TC), urea nitrogen (UN), creatinine (Cr), high-sensitive C-reactive protein (hsCRP), K+, Na+, Cl- , Ca, Mg, and phosphorus (P). Then we analyzed the correlations of the 24 biochemical markers with routine semen parameters.

RESULTSThe levels of the TP, Alb, and Glb proteins in the seminal plasma were positively correlated with sperm concentration, so was that of Alb with the total sperm count, and the AST and LDH activities with sperm concentration and total sperm count. The AKP activity in the seminal plasma was correlated negatively with the semen volume, but positively with sperm motility. The αHBDH activity exhibited a positive correlation with both sperm concentration and total sperm count, with a coefficient of correlation (r) above 0.7. The UN level was correlated negatively with the semen volume, so was the Cr level with the semen volume, sperm concentration, and total sperm count, and the Glu level with sperm concentration and total sperm count. The TG level was correlated positively with the semen volume, but negatively with sperm motility. The levels of seminal plasma ALT, GGT, ADA, UA, TC, CK, and hsCRP showed no correlation with the above-mentioned semen parameters. None of the seminal plasma K+, Na+, Ca, Mg, and P levels was found correlated with semen parameters except the Cl- level, which was negatively correlated with the semen volume.

CONCLUSIONMany biochemical markers in the seminal plasma are closely related to routine semen parameters, indicating that these biochemical components may play roles in spermatogenesis, sperm maturation, and physiological metabolism.

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

Objective To observe the protective effect of Erigeron Breviscapus(Vant.)Hand-Mazz(EBHM) on retinal ganglion cells(RGCs) and optic nerve in rabbits with elevated intraocular pressure(IOP). Methods Twenty rabbits with chronic elevated IOP were divided into two groups randomly: EBHM treated group(the ocular hypertension with EBHM treated subgroup and the normal IOP with EBHM treated subgroup) and untreated group(the simple ocular hypertension subgroup and the simple normal IOP subgroup). EBHM was irrigated into the stomachs to the treated group after IOP elevated continuously for 7 d.For light and electron microscopy studies,the rabbits' eyes were made into eyeball samples and optic nerve samples after 60 d.The density of RGCs,thickness of retinal nerve fiber layer(RNFL),and optic nerve axons were observed and quantitated by computer image analysis system.The ultra-microstructure changes of RGCs and optic nerve axons were observed by electron microscope.Results(①The RNFL) thickness,RGCs density and number of axons of the two ocular hypertension subgroups were decreased,compared with those of the two normal IOP subgroups(P

ObjectiveTo investigate the effect of both conservative and surgical treatment on cervical spinal cord injury without fracture and dislocation.MethodsResultsAll patients had some recovery after both surgical and conservative treatment(P<0.05),but the patients after surgical treatment had a better outcome than those after conservative treatment(P<0.01).ConclusionThe effect of early surgical treatment on cervical spinal cord injury without fracture and dislocation is superior to conservative.

A collection of neurons in the upper lumbar spinal cord (lumbar segments 3 and 4) of male rats project to the lower lumbar spinal cord (lumbar segments 5 and 6) and release a gastrin-releasing peptide (GRP) to the somatic and autonomic regions, which are known to regulate male sexual reflexes. The GRP plays some special functions when bound to the specific GRP receptor (GRPR). The spinal GRP system is regulated by androgens. Accumulating evidence shows that GRP plays an important role in rat penile erection and ejaculation, and pharmacological stimulation of GRPRs with a specific agonist can restore penile reflexes and ejaculation in castrated male rats. Therefore, the GRP system appears to be a potential therapeutic target for the treatment of erectile dysfunction or ejaculatory dysfunction. The present paper briefly reviews the recent studies on the role of the spinal GRP system in regulating the sexual function of males.

OBJECTIVETo investigate the effect of Sijunzi decoction (SJZD) on malondialdehyde (MDA) content and telomerase activity in heart, liver and brain tissues of D-galactose (D-gal) induced aging model mice.

METHODSD-gal aging mice model was established by cervicodorsal region subcutaneous injection with 10% D-gal once a day for six successive months. The model mice in the low-, middle- and high-dose SJZD treated groups were treated with SJZD in a dose of 6 g/kg, 12 g/kg, 24 g/kg per day respectively in the volume of 0.2 ml/10 g for 6 successive weeks. While the mice in the normal control group (NCG, non-modeled) and the model control group (MCG, modeled but untreated) were treated with distilled water instead. The MDA content and telomerase activity in heart, liver and brain tissues of mice was measured with TBA colorimetric method and PCR-ELISA respectively.

RESULTSIn MCG, the MDA content in heart, liver and brain tissues was significantly higher (P < 0.01), and the telomerase activity in liver and heart tissues was significantly lower (P < 0.01) but that in brain tissue was insignificant different to that in NCG (P > 0.05) respectively. As compared with MCG, the MDA content was significantly lower in the three SJZD treated group (P < 0.01). In comparison of telomerase activity between MCG and SJZD treated groups, it was shown that in heart tissue, there was an increased trend of the activity in the low-dose and middle-dose group, but with statistical insignificance (P > 0.05), but it did show a significant increase in the high-dose group (P < 0.05); in liver tissue no significant difference was shown between the three SJZD treated groups and MCG (P > 0.05); as for that in brain tissue, significant increase only shown in the high-dose group (P < 0.01).

CONCLUSIONSJZD can antagonize free radical injury, decrease the MDA content of heart, liver and brain in D-gal aging mice, and increase the telomerase activity in heart and brain tissues but with no effect on that in liver tissue.
