The MPN method was used to enumerate ammonia-oxidizing bacteria (AOB) in water and sediments of several shallow lakes. The suitable incubation time, medium types and substrate (ammonium sulphate) concentrations were studied. The results showed that, MPN values increased with the incubation time, reaching a stable maximum at some time stages, which was 40 days in all the samples for MSF medium. Among the three media used (XZ-AOB、MSF、SW), MSF give the highest MPN value. In addition, am- monium sulphate concentration in medium was an important factor affecting MPN estimation of AOB. Compared to AOB in lake sediments, AOB in lake water was more sensitive to ammonium sulphate concentration.

OBJECTIVETo explore the impact and effect mechanism of electroacupuncture (EA) on oocyte quali ty in the patients with infertility of kidney deficiency pattern.
METHODSSixty-six cases differentiated as kidney de ficiency and with in vitro fertilization-embryo transplantation (IVF-ET), aged fromnt 35 to 42 years were rando- mized into an observation group and a control group, 33 cases in each one. The IVF-ET therapy of the long proto- col with gonadotrophin releasing hormone agonist was adopted in the two groups. In the observation group. on the 5th day of menstruation in IVF cycle, EA was applied to Sanyinjiao (SP 6). Zigong (EX CA 1), Zhongji (CV 3) and Guanyuan (CV 4). In the control group, the sham-acupuncture was applied to the same acupoints. The treatment was given once every two days till the date of egg collection and the needles were retained for 30 min each time. The change in the score of kidney deficiency syndrome, the high-quality oocyte rate, the high-quality embryo rate and clinical pregnant rate were observed in the two groups. The levels of insulin-like growth factor-i (IGF-1) and IGF-2 in follicular fluid and the serum β-endorphin β-EP) on the date of egg collection and the correlation with oocyte quality were compared bIetween the two groups.
RESULTS1) In the observation group, the kidney deficiency syndrome score after treatment was reduced apparently as compared with that before treatment (P<0. 05), the score after treatment in the observation group was reduced much more apparently as compared with the control group (P<0.05). 2) The high-quality egg rate and the high-quality embryo rate in the observation group were both higher than those in the control group [81.3% (161/198) vs 57.6% (98/170), 59.8% (58/97) vs 37.7% (26/69), both P<0.05]. 3) Compared with the control group. the levels of IGF-1 and IGF-2 in follicular fluid and serum β-EP on the day of egg collection were all increased obviously in the observation group (all P<0. 05). 4) The levels of IGF-1 and IGF-2 in follicular fluid and serum β-EP presented the linear positive correlation with the high-quality egg rate.
CONCLUSIONEA effectively improves the expressions of IGF in follicular fluid and serum β-EP, increases the high-quality egg rate and high-quality embryo rate and relieves the symptoms of kidney deficiency.

Objective To observe the curative effects of malignant brain swelling after brain injury by using the operations of standard large Craniotomy decompression and removal of necrotic brain tissues. Methods 80 cases of malignant brain swelling after severe brain injury were observed. The standard decompression surgery of large era-niotomy routine were used in 40 cases,while the operations of standard large craniotomy decompression and removal of necrotic brain tissues were used in the other 40 cases. The curative effects of the results after 15 days and six mon-ths were analyzed. Results The incidence of intracranial hypertension (37.5%, 15/40 ) and brain tissue incisional hernia (32.5% ,13/40)of the group using standard large craniotomy decompression and removal of nee-rotic brain tissues treatment was significantly lower than that of simple standard large craniotomy decompression treat-ment group [15.0% (6/40) vs 10.0% (4/40)] after 15 days (P<0.05 ). The prognosis excellent rate ( good + re-sidual) of the group using standard large Craniotomy decompression and removal of necrotic brain tissues treatment was significantly higher (60.0%) than that of simple standard large craniotomy decompression treatment group (40.0%) after six months (P<0.05 ). Conclusion The operations of standard large craniotomy decompression and removal of necrotic brain tissues can effectively reduce the intracranial hypertension of malignant brain swelling after trauma injury,and reduce mortality and morbidity of severe brain injury.

Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Moyamoya disease is a rare cerebrovascular disorder, characterised by progressive stenosis and/or
occlusion of the intracranial internal carotid artery and its proximal branches with the development
of a basal collateral network. Moyamoya disease has a high prevalence in Asia, particularly in Japan,
Korea and China. Ischemic events and intracranial bleeding are the most common clinical manifestation
of moyamoya disease. Although the benefi cial effect on hemorrhage is still not clear, revascularisation
surgery remains the most effective way to prevent the progression of ischemic symptoms. Moyamoya
disease has been investigated by numerous studies since it was fi rst described 50 years ago, many
conundrums remain to be solved. In this article, we review the history, epidemiology, aetiology, clinical
manifestation, diagnosis and treatment of moyamoya disease. Recent advances and future challenges
of moyamoya disease are also discussed.

Objective To explore the clinical features, characteristics of neuroimaging and prognosis of toxic encephalopathy induced by 1,2- Dichloroethane. Methods The clinical features,characteristics of neuroimaging and prognosis in eight cases with toxic encephalopathy induced by 1,2- Dichloroethane were analyzed retrospectively. Results In acute or subacute stage of toxic encephalopathy induced by 1,2- Dichloroethane, the whole brain injury symptoms and severe intracranial hypertension were the main neurological manifestations. CT and MR examination showed diffused encephaledema and brain swelling. DWI test showed the symmetric diffused low density lesions in white matter of cerebral hemisphere,and the average values of ADC decreased significantly. With the disease improving, the brain swelling was alleviated, the brain lesion foci reduced gradually, and the average values of ADC increased. The prognosis will be improved dramatically if sufficient mannitol, hormone and high pressure oxygen were used in the early stage. Conclusion The diagnosis of toxic encephalopathy induced by 1,2- Dichloroethane depends mainly on the clear toxicant contact history, clinical features and characteristics of neuroimaging. Taking effective measures in the early stage to control actively the encephaledema would be beneficial to the prognosis.
