Kyrgyzstan is a mountainous country in the northeastern part of Central Asia which shares borders to the southeast with China. Due to their extreme environment and climate, there are a diverse range of species of plants. Many of the plants used in Kyrgyz folk medicine have not been studied using modern scientific techniques. This paper introduced the basic situation of medicinal herbs in Kyrgyzstan by comparing the differences traditional use between China and Kyrgyzstan, and looked for traditional medicinal plant research to provide basis for the development and cooperation of China and Kyrgyzstan.

To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

Objective To summarize the clinical effect of urethroplasty using acellular dermal matrix patch for the treatment of anterior urethral stricture caused by lichen sclerosus.Methods The clinical data was analyzed retrospectively from 15 patients with anterior urethral stricture caused by lichen sclerosus treated with aeellular dermal matrix patch.Results The patients were followed up for 8-40 months.The urethral silicone stent was removed 4 weeks after operation in 15 cases and all the patients voided well 2 months after operation.The urinary peak flow rates ranged from 17.6 to 41.7 ml/s(mean,28.6ml/s).Urethral stricture occurred in 2 patients 3 months after operation undergoing discontinuous dilatation within 3 to 6 months,the patients voided very well.Conclusion It is feasible,safe and relatively simple to use acellular dermal matrix patch for anterior urethral stricture caused by lichen sclerosus.

Objective To investigate the effects of different magnitudes of mechanical stress on human interverte-bral disc degeneration. Methods The human intervertebral disc cells were subjected to different magnitudes of mechanical stress (0, 6%, 12%, or 18%elongation) for 24 h using a Flexercell Strain Unit. The mRNA expressions of anabolic genes (col-lagen-1A1, collagen-2A1, aggrecan and versican) and catabolic genes (MMP-3, MMP-13, ADAMTS-4 and ADAMTS-5) were examined by real-time PCR and Western blot methods. Results The expression levels of collagen-1A1 and collagen-2A1 were increased at 12%of mechanical stress, and collagen-2A1 was decreased at 18%of mechanical stress compared with those of control. The mRNA expressions of catabolic genes, MMP-13 and ADAMTS-5, were increased at 12%and 18%of mechanical stress than those of control. The mechanical stretch induced a magnitude-dependent increase in ADAMTS-4 synthesis, which was finely tuned by stretching-triggered activation of distinct mitogen-activated protein kinase cascades. Specifically, an ERK1/2 specific inhibitor, U0126, significantly inhibited the stretching-induced ADAMTS-4 expression, whereas the inhibitors of p38 and JNK, SP6000125 and SB203580, showed only slightly effect on the stretching-induced ADAMTS-4 expression. Conclusion The different magnitudes of mechanical stretch exhibited different effects on the bio-logical behavior of intervertebral disc cells, which profoundly affects the intervertebral disc degeneration.

To study photosynthetic characteristics and its influencing factors in leaves of medicinal plant Mirabilis himalaica, and provide an evidence for guiding artificial planting and improving the quantity. The light-response and diurnal photosynthesis course of leaves at the booting stages of 1-3 year old M. himalaica were measured with LI-6400 system. The Results showed that the light response curves were fitted well by non rectangle hyperbola equation (R2 > or = 0.98). The values of the maximum photosynthetic rate (Pmax) and light use efficiency of three-year old M. himalaica leaves were higher than those of 1-2 year old individuals. The diurnal variation of net photosynthetic rate (Pn) and stomatal conductance (Gs) of 2-3 year old M. himalaica were typical double-peak curves determinately regulated by stomatal conductance. However, transpiration rate (Tr) of 1-3 year old plants leaves were single-peak curve, which was self-protection of harm reduction caused by the higher temperature at noontime. Correlation analysis showed that the changes between photosynthetic active radiation (PFD), air temperature (T ) and Pn, were significant positive related. Therefore, M. himalaica is a typical sun plant, which should be planted under the sufficient sunshine field and prolong the growing ages suitably in order to improve the yield.

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

OBJECTIVETo study the causes of failure following surgical treatment of lumbar spondylolisthesis, procedures for redo surgery and the final result of reoperation.

METHODS20 patients who had a repeat operation for lumbar spondylolisthesis were studied retrospectively. On average 24.3 months following the previous surgery, all of these patients had recurrence or progression of back and leg pain. All of 20 patients were reoperated by means of three different procedures.

RESULTSThe causes of failure were post-operative destabilization (6 cases); progressive spondylolithesis (3 cases) implants failure (10 cases) and mistake segment (one case). After reoperation, a mean 34.1 months' follow-up was made. The excellent or good rate was 90%. Incorporation of graft was found in 18 cases with fusion by inter-transverse process and 2 cases by intervertebral space. New bone formation was found in 6 out of 8 cases that had a simultaneous intervertebral cage implant. No implant failure was found in all patients.

CONCLUSIONSSimple laminectomy or discectomy was not indication for lumbar spondylolithesis. No bone graft or union was the main causes of implant failure. Posterior instrumented fusion with laminectomy decompression can be used in the patients who had a prior surgery of simple discectomy or anterior intervertebral bone graft. Except for posterior instrumented fusion with extensive laminectomy decompression, Intervertebral fusion should be considered in the patients who had a prior surgery of laminectomy decompression with instrument, anterior intervertebral fusion (ALIF) was recommended for these cases.

OBJECTIVETo study the treatment of spinal fractures in ankylosing spondylitis.

METHODSNineteen cases of spinal fractures complicating ankylosing spondylitis admitted in our hospital were studied retrospectively.

RESULTSAll of 19 cases were up to the diagnosis standards of ankylosing spondylitis. Eleven patients had cervical fracture and 8 had thoracolumbar fracture. Of the patients with cervical fracture, fractures occurred at C(5 - 7) in 9 patients. Of the patients with thoracolumbar injury, stress fractures were seen in 7 patients and all of seven fractures occurred at T(10)-L(2). Sixteen of the 19 patients sustained fractures through three columns of the spine. Nine patients had spinal cord injures; eight of the 9 cases had cervical fracture. All of the 19 patients were treated operatively. Four different surgical procedures were used in patients with cervical fracture; decompression, fusion and stabilization with instrumentation by anterior approach were performed in 9 patients. Of the patients with thoracolumbar fractures, four different operations were performed; fusion by both anterior and posterior approach plus a long posterior instrument were used in 5 cases. Eighteen patients had an average follow-up period of 46.6 months. Nine patients with preoperative neurological deficits improved in 8 and was stabilized in 1. Radiographic evidence of fusion was observed in all of the 18 patients. Two patients suffered neurological deterioration during surgery. One patient died from cerebrovascular infarction. Two patients had pneumonia after the operative procedure.

CONCLUSIONSSpinal fractures in ankylosing spondylitis are associated with a high rate of neurological injury. Shearing fracture usually occurs at the lower cervical spine (C(5 - 7)) and stress fracture at thoracolumbar spine. Most of the fractures involve three columns of spine. Surgical intervention may be indicated in this injury. Fracture union and neurological improvement can be achieved in most patients treated by operation. We suggest that, fusion and stabilization with instrumentation by anterior approach is indicated in most cervical shearing fracture, and a combined fusion by both sides plus a long posterior instrument is probably beneficial in patients with thoracolumbar stress fracture. Complications is not rare after surgery and appropriate preventive measures are necessary for these patients.
