Sodium glucose co-transporter (SGLT) is one of the transporters responsible for the resorpcion of glucose, and inhibition of its activity can decrease the resorption of glucose. Human SGLT is mainly composed of SGLT1 and SGLT2. Due to the specific distribution and the high efficiency of SGLT2, SGLT2 inhibitor is a potential new strategy for treatment diabetes. Abundant animal experiments and clinical trails have found that SGLT2 inhibitor can greatly lower the blood glucose and help to lose weights. However, the current researches about SGLT2 inhibitor are still very limited both in depth and in broadness; problems concerning the safety, efficacy and indication of SGLT2 inhibitor still need to be further studied.

Objective To explore the curative effect of minimally invasive percutaneous nephrolithotomy in treatment of recurrence of kidney stones after open operation.Methods 56 patients with postoperative recurrence of renalcalculi were retrospectively reviewed.They were randomly divided into the control group and the observation group.The observation group was treated by minimally invasive percutaneous nephrolithotomy,while the control group received the open operation.The stone clearance rate,operation time and hospitalization time of the two groups were compared.Results The stone clearance rate in the observation group was 92.86％,which was significantly higher than 64.29％ of the control group (x2 =11.37,P ＜ 0.05) ; The average operation time in the control group was (131.8 ± 8.9)min,which was more than (92.5 ± 5.4)min of the observation group ;The average hospital stay in the control group was (19.7 ± 3.2) days,which was more than (10.4 ± 2.6)days of the observation group,the differences were statistically significant (t =16.38,17.25,all P ＜0.05).Conclusion Minimally invasive percutaneous nephrolithotomy can improve the stone clearance rate in treatment of recurrent renal calculi after open operation,which can shorten the operation time and hospital stay,it is worth the clinical promotion.

AlM: To observe the treatment efficacy of eyelid herpeszoster with external use ganciclovir ophthalmic gel.METHODS:A total of 77 patients were randomly divided into treatment group and control group. ln the treatment group, ganciclovir ophthalmic gel was topical coated on the basis of antiviral drugs, while the control group was coated with conventional acyclovir ointment and antiviral treatment.
RESULTS: The cure rate was 95% in the treatment group, and the control group was 83% after 10d treatment. The difference was significant.
CONCLUSlON: The efficacy of ganciclovir ophthalmic gel treated eyelid herpes zoster is obvious.

BACKGROUND: At present, bone defects usually repaired by autologous bone, allogenic bone, synthetic bone substitutes and other methods, which received poor clinical results. Preliminary studies have shown that adipose-derived mesenchymal stem cells (ADSCs) possess strong proliferation ability and differentiation potential, and can be induced differentiate into bone. OBJECTIVE: To analyze the application of ADSCs in bone tissue engineering, and to identify whether ADSCs can be used as seed cells in bone tissue engineering. METHODS: The databases of PubMed (1999-01/2008-12) and Tongfang (2003-01/2008-12) was retrieved using key words of "adipose tissue-derived mesenchymal stem cells, adipose mesenchymal stem cells, adipose stem cell; osteogenic induction, osteogenic inducement, bone induction, osteoblastic induced; chondroblast induction, cartilage induction; bone tissue engineering, tissue engineering bone, tissue engineering of bone". RESULTS AND CONCLUSION: A total of 361 literatures were collected, including 246 in Chinese and 115 in English. Totally 29 literatures were accordant with the study criteria. ADSCs is a truly multi-directional differentiation potential cells, which possess strong amplification and self-renewal potential, and can be directional differentiated into osteoblasts, cartilage cells, bone cells and muscle cells. It can be used as seed cells in bone tissue engineering when matching appropriate stents.

Objective To explore the measures to prevent recurrent laryngeal nerve (RLN)injury during thyroid surgery.Methods The clinical data of 223 patients undergone thyroid surgery were retrospectively analyzed.Among the 223 surgeries,69 sides were undergone regional protection act of RLN and 191 sides were performed RLN exposure.Results There were 2 cases of RLN injury from the regional protection operation of RLN,including 1 case of temporary nerve injury which could be resulted from surgery clamp and 1 case of permanent nerve injury which might be caused by mistaking ligation during surgery.There was only 1 case of temporary nerve injury in RLN exposure procedure which was probably caused by the postoperative nerve edema and was recovered 2 months after the operation.The total RLN injury rate was 1.35％.Conclusion For benign thyroid lesions and non-dorsal lesions or during partial excision of the gland,the regional protection of RLN is helpful to prevent RLN injury.In cases with dorsal lesions of thyroid or contralateral RLN injury,or during lobe subtotal resection,lobe resection and reoperation,exposing RLN to prevent injury is necessary.Taking different approaches based on the profiles of lesions and surgical procedures to prevent RLN injury can significantly reduce the risk of RLN injury.

Objective To explore the feature and the optimal treatment of kidney stones in children associ-ated with infant formula which had been aduherated with melamine.Method Total of 47 cases of urinary stone and 31 cases of acute renal failure caused by urinary multiple obstruction in children associated with infant formula which had been adulterated with mlelamine in Beijing Children's Hospital University of Medical Science,form Jan-uary to November,2008 were retrospectively analyzed.Results Infant formula which had been adultemted with melamine may lead to kindey stones in 15 days.The mean age was 11-month and the ratio of male to female was 2.6:1.The kindey stones were usually multiple and mostly located either in the ureteropelvic junction or all through the ureter.In the view of the renal function resuming duration,there was no statistic difference among the acute renal failure group,operation group and the conservative group(P=0.683～0.846).In children with uri-nary obstruction and acute renal failure,hemedialysis or peritoneal dialysis was performed.83.9%were relieved by posting catheter through panedoseope and blood purification.100% of the patients resumed normal renal func-tion.81.3% of the patients without acute renal failure had recovered after conservative therapies such as infusion.Conclusions The patients associated with infant formula which had been adulterated with melamine were Usually little infants.Male were more vulnerable than female.Most of them had recovered smoothly and the renal function resumed normal after effcient therapies.

Discogenic low back pain is the common type of chronic low back pain. However,its mechanism has not been completely clarified. Considerable evidence shows that neurotrophins play an important role in discogenic low back pain. The paper summarizes the mechanism of neurotrophins on discogenic low back pain according to the pain transfer pathway of neurotrophins in intervertebral disc, dorsal horn ganglia and spinal trigeminal nucleus. Changing the pain transmission by regulating neurotrophins and its receptor will provide a new way for the treatment of discogenic low back pain.
