OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.

METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.

RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).

CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

OBJECTIVETo explore the correlation of the mutation of MTCYB and MTATP6 genes in sperm mitochondria with asthenospermia.

METHODSWe extracted mtDNA from 80 semen samples of asthenospermia and 20 of normal sperm motility, amplified the MTCYB and MTATP6 genes by PCR, and analyzed their mutation by sequencing and BLAST matching.

RESULTSThe deletion of both MTCYB and MTATP6 were detected in 20 of the 80 asthenospermia samples, MTCYB deletion in 16 and MTATP6 deletion in 4, accounting for 20% and 5% respectively. Sequencing and BLAST matching revealed G8887A mutation in the MTATP6 gene in the asthenospermia samples, with a mutation rate of 20%, while no regular mutation was noted in MTCYB. Neither significant deletion nor mutation was observed in any of the 20 samples of normal sperm motility.

CONCLUSIONBoth the deletion and mutation of MTCYB and MTATP6 genes in sperm mitochondria might affect sperm motility in adults.

One of the most common causes of male infertility is asthenospermia, whose pathogenesis, however, is not yet clear. Recent researches have found that some genes (such as tektin-2, DNAI1, DNAH5, DNAH11, AKAP4, SEPT4 and Smcp) and proteins (such as sperm proteins ACTB, ANXA5, PRM1, PRM2 and SABP and seminal proteins Tf, PSA, PAP and Fractalkine) are associated with asthenospermia. The finding of these molecular markers has provided a base for the explanation of the molecular mechanism of asthenospermia, and these markers may become the diagnostic and therapeutic targets of the disease.

OBJECTIVETo appraise the effect of single- and two-layer Percoll density gradient centrifugation in sperm separation.

METHODSTwenty semen specimens underwent single-(50%) and two-layer (90% and 45%) density gradient centrifugation, respectively. The sperm class analyzer (SCA) was used to analyze sperm density, motility and dynamic parameters and round cell density before and after the treatment.

RESULTSAfter separation, the sperm recovery rate of the single-layer method was (65.5 +/- 12.8)%, significantly higher than that of the two-layer method (P < 0.01). The percentages of grade a sperm of the single- and two-layer method were significantly higher than pre-treatment (P < 0.05, P < 0.01), that of the single-layer was significantly lower than that of the two-layer method (P < 0.05), but the percentage of grade c sperm of the former was significantly higher than that of the latter (P < 0.05). Compared with pre-treatment, the percentage of grade a + b sperm of the two-layer method was significantly higher (P < 0.05), while that of the single-layer method showed no significant difference (P > 0.05), and the round cell density of both the methods was significantly lower (P < 0.05, P < 0.01), with no significant differences between the two methods (P > 0.05).

CONCLUSIONThe single-layer method yields a higher rate of sperm recovery and causes little change in the sperm motility, while the two-layer method effects a lower rate and significantly improves sperm motility. Both the methods can efficiently separate sperm from round cells, and each has its own advantages and its application value in in vitro treatment of sperm.
