The project of counterpart assistance has made great achievements, however, the outlay shortage has become the key restriction in sustainable development and role playing as expected. From the view of long-term development and marketing point, it is a must to discuss the issue of “establishing the satisfied system (or active system) to enhance the development of the universities in the west and how to stimulate these universities to enter into the system”. From the economic model in this paper, we can clearly conclude that the government has played a significant role in the process of the development of the universities in the western part of China.

AIM: To establish a simple and repeatable orthotopic animal model of the A549 cell line.METHODS: A549 cells in matrigel were inoculated into left lung or right flank of nude mouse. The growth pattern of A549 tumors and the chemotherapeutic efficacy of carboplatinum were studied. RESULTS: Tumors generated and dispersed widespreadly to contralateral lung. Tumors in lung were less susceptible to carboplatinum than those growing in flank. CONCLUSION: A simple and repeatable orthotopic animal model of the A549 cell line was presented, this allows researchers to evaluate novel compounds and new drugs for treatment of human lung cancer.KEY WORDS A549 cell line; orthotopic model; nude mice

Objective To explore the relationship between osteoporosis and chronic vascular complications in elderly male patients with type 2 diabetes and to evaluate its related risk factors.Methods A retrospective study was conducted in 428 elderly type 2 diabetic patients.The bone mineral density (BMD) of lumbar spines (L2 ～L4),femoral neck,Ward's triangle were measured by dual X-ray absorptiometry,and chronic vascular complications in patients were tested.The correlation between BMD and chronic vascular complications was analyzed.Results Diabetic course was longer in osteoporosis group than in non-osteoporosis group (P＜0.05).Levels of fasting blood glucose (FBG) and postprandial blood glucose (PBG) were significantly higher in osteoporosis group than in non-osteoporosis group (P＜ 0.05).The incidences of diabetic nephropathy,diabetic retinopathy,diabetic neuropathy and hypertension were higher in osteoporosis group than in non-osteoporosis group (59.8％ vs.12.0％,41.8％ vs.22.3％,33.6％ vs.24.5％,and 35.7％ vs.26.1％,respectively,all P＜0.05).Logistic analysis showed that diabetic course,FBG and diabetic nephropathy were correlated with diabetic osteoporosis (OR =1.055,1.168,7.401,95％ CI:1.015-1.096,1.073-1.273,4.303-12.727,P=0.007,0.001,0.001).Conclusions Osteoporosis has a close relationship with diabetic microvascular complications in elderly diabetic patients.Diabetic nephropathy plays an important role in the development of diabetic osteoporosis.It is helpful for osteoporosis prevention to early monitor and intervene on microvascular complications index such as urinary albumin in elderly patients with type 2 diabetes.

AIM: To study the effect of Lomerizine on the activity of P-glycoprotein (P-gp) in the bloodbrain barrier(BBB) and search for novel effective P-gp inhibiting agent against multidrug resistance. METH-ODS: Rhodamine123 (Rh123) was used to examine the activity of P-gp and RT-PCR to study the mdr mRNA expression in cultured rat brain microvessel endothelial cells (RBMECs). RESULTS: Lomerizine could increase the cellular Rh123 in RBMECs in a concentration-dependent manner. RT-PCR indicated that lomerizine could not down-regulate the expression of mdr mRNA. CONCLU-SION: Lomerizine can reverse multidrug resistance in the blood-brain barrier by inhibiting the activity of P-gp.KEY WORDS lomerizine; P-glycoprotein; bloodbrain barrier; RT-PCR

Objective To evaluate clinical features, therapeutic regimen and prognosis of unexplained rhabdomyolysis. Method Clinical manifestations, therapeutic regimen and prognosis were recorded in 23 patients,who were admitted to The First Affiliated Hospital of Nanjing Medical University 13 to 27 August,2010.The 23 patients were diagnozed as unexplained rhabdomyolysis. Results The patients all presented myalgia of upper body,like neck,waist and back,maybe with asthenia, nausea,dyspnea,abdominal pain, red urine or changed color of urine. Laboratory examination: obviously step-up of creatine kinase [CK: (4655 ± 2556) U/L( normal: 25 ～ 190U/L) AST:(141 ±78) U/L(normal:10～45 U/L),LDH:(348± 127) U/L(normal: 110～ 250 U/L)]and myoglobin[( Mb ＞ 1000 μg/L (normal: 0 ～ 50 μg/L)]. Therapeutic regimen included treatment of the underlying diseases, volume repletion, alkalization and dealing with the complications. No patients developed acute renal failure.All the patients recovered. Conclusions Rhabdomyolysis is a syndrome with different clinical manifestations.However, early diagnosis, proper treatment could prevent serious complications,and prognosis is good.

Objective To explore the management of benign prostatic hyperplasia(BPH)by photoselective vaporization of prostate(PVP)and curative effect in the near future. Methods Clinical data of 60 BPH patients underwent PVP were retrospctively aralyzed.The changes of IPSS and QOL and the max urine flow rate and residual urine volume(RUV)perioperatively were compared through observations of the operation time and complication. Results The therapeutic efficacy was favourable.No transurethral resection of prostate(TURP)syndrome and uroclepsia happens.IPSS(t=2.471,P <0.05)and QOL(t=2.392,P <0.05)and the max urine flow rate(t=2.287,P ＜0.05)and residual urine volume(t=2.513,P＜0.05)obviously improved(P ＜0.05). Conclusion PVP had many advantages such as operated simply and no serious complications.It was a good operation method to treat BPH.

OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

Objective To explore the management,curative effect and safe of superficial bladder tumor(BT)by greenlight photoselective vapontion per urethra(GPVPU). Methods 32 patients of BT were treated by GPVPU,and operation time,postoperative complications,relapse rate and so on were observed. Results All cases were completed successfully. No complication happened in operations. Urinary canal was detained 2 ～4 days and bladder washout(BW) did not need after operation. Follow-up average time was 16 months. Irrigation chems of bladder and cystoscopy were applied routinely. Conclusion GPVPU was safe and effective in treatment of superficial bladder tumor.

Objective To explore the relationship of the level of serum selenium and infantile diarrhea,provide foundation for establishing the therapeutic criteria.Methods Seventy-eight diarrhea children was enrolled in this study,6 -24 months old.Thirty children with acute diarrhea (AD group),26 children with persistent diarrhea (PD group) and 22 children with chronic diarrhea (CD group).The level of serum selenium was measured and compared with another 30 healthy children (control group) of matched sex and age.The level of serum selenium of CD group was compared before and after the recovery.Results The level of serum selenium in AD group and PD group had no significant difference compared with control group [ (51.34 ± 4.84),(48.14 ± 3.05 ) μ g/L vs.(55.08 ± 5.59 ) μ g/L ] (P＞0.05 ).But the level of serum selenium in CD group was significantly lower than that in control group [ (42.13 ± 5.16) μ g/L vs.(55.08 ±5.59) μg/L] (P＜0.05).After treatment for 1 month,the level of serum selenium in CD group was significantly increased than before treatment [ (53.76 ± 8.38 ) μ g/L vs.(42.13 ± 5.16) μ g/L ] (P＜0.05 ).Conclusions The nosogenesis of chronic diarrhea may relate with the level of serum selenium decrease.Therapeutic selenium supplement is important in children with chronic diarrhea.

AIM To study the therapeutic effect of bone marrow transplantation on mustard gas-poisoned mice. METHODS Mustard-poisoned mice model was constructed by injected mustard gas 20 mg·kg~(-1) subcutaneously. At 4 h, 1 d and 2 d after poisoned by mustard gas, the suspended bone marrow cells (106 cells per time) were injected into mice respectively. After poisoned 3, 5, 7 and 10 d, the numbers of leukocyte and marrow nucleated cells were recorded periodically. At the same time, after poisoned 4 h and 1 d by mustard gas, mice in another group were injected granulocyte colony stimulating factor (G-CSF) 74 μg·kg~(-1) combined with transplantation and changes of the cell number were observed. RESULTS Compared with poisoned group without transplantion, leukocyte number in bone marrow transplanted group presented ascending trend, but there was no statistical significance until the 10 d after poisoned. However, the number of marrow nucleated cell increased significantly from the 5th day. After mice injected bone marrow cells combined with G-CSF, leukocyte increased markedly in earlier stage compared with transplantation only. CONCLUTION The bone marrow transplantation has significant effects on improvement of marrow hematogenic system inhibited by mustard gas.
