ObjectiveTo investigate the clinical efficacy of points injection of mouse nerve growth factor in treating sciatic nerve injury.MethodAcupuncture point injection of injectable mouse nerve growth factorwas performed in 60 patients with sciatic nerve injury. Points Huantiao(GB30)and Zusanli(ST36)were selected. Treatment was given once daily, for a total of 30 times. Sensory and motor functions were assessed (MS and SS) and electromyography (EMG) was performed before and after treatment to compare motor nerve conduction velocities (MCV) and sensory nerve conduction velocities (SCV) in the injured nerves and EMG changes in the musclescontrolled by the injured nerves.ResultAfter treatment, nerve function was restored to more than S3M3, with an efficacy rate of 81.7%, in 49 patients. Neuro-electrophysiological study showed that regenerative potentials occurred, accounting for 71.7%,in43patients. Denervated potentials were fewer after treatment than before; there was a significant difference (P<0.05). The mean MCV value increased after treatment compared with before; there was a significant difference (P<0.05). ConclusionAcupuncture point injection of mouse nerve growth factor can markedly improve sensory and motor functions in the regions controlled by the injured sciatic nerve. It provides an effective way to promote the repair of sciatic nerves and the reconstruction of limb function after the nerves are injured.

At the urgent request of Artemisia annua (ART) planting, the paper gets artemisinin content (ARTC) of ART in China from literatures. The paper analyses the relationships between ARTC and ecological factors by statistical analytical methods. The paper also analyses the climate suitable rank distribution of ARTC in China by ArcGIS. The results display that first, ARTC is significantly different in China, that ART from the south regions ARTC is higher. Greatest north parts of China have not suitable climate for the growing of ART and the ARTC is lower than 0.2%, when ART grows above the 34th degree of northern latitude. ARTC is higher and ART grows well, when ART grows under the 34 degrees N and grows at the areas between 100 degrees E and 120 degrees E. Second, subtropical zone is the best suitable climate zone for the growing of ART. ART grows well and ARTC is higher than 0.5%, when ART grows in the subtropical zone. Third, temperature, sunshine duration and rainfall are the main ecological factors that affect the growth of ART and the accumulation of ARTC. That the year temperature between 13.9 degrees C and 22 degrees C, sunshine duration between 853 h and 1507 h, rainfall between 814 mm and 1518 mm, is the best climate for the accumulation of ARTC. Temperature between 13 degrees C and 29 degrees C, rainfall between 600 mm and 1300 mm is the best climate for the growth of ART. Fourth, in northwest of Guangxi, eastern of Sichuan, Guizhou and Yunnan provinces, south Chongqing and west Hunan Province, there are suitable climate for the growth of Artemisia and for the accumulating of ARTC. There are also some suitable climate areas for the growing of artemisia in the south of Hubei, Anhui and Jiangsu provinces.

Methods Atotalof54SDratsweredividedinto6groupsaccordingtothedigitalrandommethod:a control,a sham operation,a model,a low-dose,a medium-dose,and a high-dose NaokangⅡ group (the low-,medium-,and high-dose groups were 5,10,and 20 times of adults (n=9 in each group). A rat model was induced by ligate the bilateral common carotid arteries permanently. The bilateral common carotid arteries were only isolated but not ligated in rats of the sham operation group. The rats in the control group were not given any treatment. After modeling,the rats in the treatment groups were treated with NaokangⅡ. The rats in the control,sham operation,and model groups were given equal volume of isotonic saline (2 ml). Morris water maze test and space search experiment were used to evaluate the learning and memory abilities in rats 9 weeks after modeling. Immunofluorescence staining and immunohistochemical methods were used to observe proliferation and differentiation of neural stem cells (NSCs). Western blot was used to detect the expression of autophagy related protein Beclin-1 and LC-3Ⅱ. Results (1 )The escape latencies of the model group from 1 to 5 days were 100 ± 13,98 ± 13,82 ± 14,72 ± 15,and 46 ± 7 s,respectively. They were significantly longer than those of the sham operation group and the control group (all P<0. 05). The search distances were 1239 ± 127,1011 ± 122,959 ± 123,553 ± 66,and 407 ± 29 cm,respectively. They were significantly increased as compared with those of the sham operation group and control group (all P<0. 01). Both the escape latencies and search distances of the rats in the Naokang Ⅱ low-,medium-,and high-dose groups were significantly shorter than those of the model group (P<0. 05). The escape latencies on the fifth day were 20 ± 6,19 ± 8,and 15 ± 6 s,respectively,and the search distances were 234 ± 38, 297 ± 23,and 99 ± 22 cm,respectively. Nine weeks after modeling,the quadrant search time on the original platform in the rats of the model group was 30 ± 9 s,it was significantly shorter than that of the sham operation group (P<0. 01). The quadrant search time on the original platform of the Naokang Ⅱ low-, medium-,and high-dose groups were 34 ± 6,38 ± 8,and 40 ± 10 s,respectively. They were significantly longer than those of the model group (P <0. 01). (2)Nine weeks after modeling,the results of immunofluorescence and immunohistochemistry showed that the number of BrdU-positive cells and the Nestin positive cells in hippocampal dentate gyrus of the model group were higher than those of the control group and the sham operation group (P<0. 05). The number of BrdU-positive cells and Nestin positive cells of Naokang Ⅱ each dose group were significantly higher than those of the model group (P<0. 05). The expression of LC-3Ⅱand Beclin-1 in the model group was significantly higher than those in the control and sham operation groups (P<0. 01). The expression of LC-3Ⅱ in the medium- and high-dose groups was 143 ± 9 and 129 ± 9 respectively,and the expression of Beclin-1 was 139 ± 10 and 124 ± 7 respectively, andtheyweresignificantlylowerthanthemodelgroup(P<0.01).Conclusion NaokangⅡcanimprove the cognitive function in rats with cerebral ischemia,promote neurogenesis in the dentate gyrus,and inhibit autophagic cell death.

Objective To study the characteristics and diagnosis of renal sinus lipomatosis (RSL) complicated with renal staghorn calculi, and report our preliminary experience on percutaneous nephrolithotripsy for the disease. Methods A total of 547 patients with complex renal calculi were admitted to our hospital from January 2005 to June 2007. In 2 of them, RSL complicated with renal staghorn calculi was diagnosed by B-ultrasonography, CT, and MRI. Both the patients were female, aged 42 and 82 years respectively. B-ultrasonography-guided percutaneous nephrolithotripsy was performed on the two patients without removing the kidneys.Results Totally, 7 ml and 5 ml of stones were removed respectively from the two patients by percutaneous nephrolithotripsy. No retained calculi were found by KUB performed one week postoperation. Biopsy of the submucosal fat obtained from the renal pelvis during the operation showed hyperplasia and fibrosis of fatty tissues and inflammatory effusion. The patients were followed up for half a year, during which no recurrence of renal calculi occurred, and no abnormal fatty tissues were found at the renal sinus or surrounding the kidney. Conclusions Imaging examination is valuable for the diagnosis of RSL. B-ultrasonography-guided percutaneous nephrolithotripsy is safe and effective for RSL complicated with renal calculi.
