1.Identification of multi-component in Danshen Dropping Pills by using a combinative LC/MS approach
Chinese Traditional Patent Medicine 1992;0(01):-
AIM: To develop a combinative LC/MS for the identification of multi-component in Danshen Dro-(pping) Pills(Radix et Rhizoma Salviae miltiorrhizale,Radix et Rhizoma Notoginseng,Borneolum Syntheticum,etc.). METHODS: Separation was performed on a Phenomenex Luna C_(18) reverse-phase column(250 mm?4.6 mm,5 ?m).The mobile phase consisted of water containing 0.2% formic acid and acetonitrile was used as gradient elute.The flow rate was 1 mL/min.A combination of time-of-flight mass spectrometer(TOF-MS) and ion trap tandem mass spectrometer(Trap-MS~n) was applied for qualitative analysis under negative ion mode. RESULTS: Under optimized LC/MS condition,the molecular formulae of 14 components were screened by TOF-MS and 13 of them were then identified by Trap-MS~n.All of the components were surveyed and classified according to their medicinal materials derivation. CONCLUSION: The established combinative LC/MS method can thus be considered as an effective and credible pattern for the analysis of Chinese multi-herb remedy,as well as other complex systems.

3.A review on selective laser trabeculoplasty
Chinese Journal of Experimental Ophthalmology 2016;34(7):654-657
Glaucoma is an irreversible blinding disease.The aim of glaucoma therapy is to lower the intraocular pressure (IOP),and then slow down glaucoma progression.Currently,this goal can be achieved by medication,laser treatment and surgery.Selective laser trabeculoplasty (SLT) involves using a 532 nm wave length Nd:YAG laser selectively target cells of the trabecular meshwork without causing thermal or collateral damage to the surroundings structures.The exact mechanism by which SLT lowers IOP remains unknown.It has become gradually one of the most preferred methods for the treatment of open angle glaucoma.SLT seems to have a similar IOP lowering effect with argon trabeculoplasty or monotherapy of topical prostaglandin medication.Mean IOP reduction after SLT was 3.8-8.0 mmHg in 6 months to 1 year.The long-term effect of SLT in the treatment of open angle glaucoma remains to be further studied.The relationship between the range of SLT treatment and its therapeutic effect has not been recognized.SLT is efficacious and safe,also has repeatable and less adverse effects.It can be used as an efficacious primary,adjunctive and replacement therapy for treating open angle glaucoma.In this paper,we reviewed the effects of SLT as an initial and repeat treatment,also the factors that could affect therapeutic effects.

Chinese Journal of Digestive Surgery 2014;13(5):341-344
Objective To investigate the value of laparoscopic cholecystectomy through superior margin of public symphysis approach.Methods The clinical data of 72 patients with benign gallbladder diseases who were admitted to the Lihuili Hospital from December 2012 to August 2013 were retrospectively analyzed.There were 54 patients with cholecystolithiasis and 18 with gallbladder polyps.Thirty patients received laparoscopic cholecystectomy through the superior margin of public symphysis approach (new method group).Forty-two patients who received transumbilical single-port laparoscopic cholecystectomy were in the control group.The operation time,intraoperative blood loss,duration of postoperative hospital stay,degree of postoperative pain and cosmetic effect of the 2 groups were compared.Patients were followed up via out-patient examination and phone call till December 2013.Data were analyzed using the t test or chi-square test.Results Two patients in the new method group and 1 patient in the control group were converted to receive traditional laparoscopic cholecystectomy.The operation time,intraoperative blood loss,duration of postoperative hospital stay,scores of satisfaction with the incision and degree of postoperative pain were (28 ± 3) minutes,(23 ± 10) mL,(2.0 ± 0.5) days,4.3 ± 0.5 and 5.8 ± 0.8 in the new method group,and (39±4)minutes,(24±l0)mL,(2.0±0.6)days,3.9±0.5 and 5.9±0.9 in the control group.There were significant differences in the operation time and score of satisfaction with the incision between the 2 groups were detected (t =10.032,2.423,P < 0.05),while no significant differences in the volume of intraoperative blood loss,duration of postoperative hospital stay and degree of pain between the 2 groups (t =1.021,0.000,1.760,P > 0.05).All the patients were recovered,and were administered with semi-fluid food at postoperative day 2.No bleeding,bile leakage,incisional infection occurred,and no patient died perioperatively.Analgesics were not needed in the 2 groups.All the patients were followed up for 1-6 months.Patients were satisfied with the cosmetic appearance of the incision,and no inflammation,pain and infection of the incision occurred.Conclusions Laparoscopic cholecystectomy through the superior margin of public symphysis approach is safe and feasible,with the advantages of short operation time,cosmetic appearance of incision and easy manipulation.

Objective To explore the role of intracellular Ca~(2+) in inhibition of axonal outgrowth,which could learn more about the signal transduction mechanism of Nogo-A inhibiting axonal outgrowth. Methods Using laser confocal microscope,intracellular calcium level in cerebellar granule neurons after Nogo-A added in different times was measured and the effect of Nogo-A inhibiting axonal outgrowth when priming nimodipine was observed. Results The concentration of Ca~(2+) increased in 5 minutes after Nogo-A added,and reached to peak in 30 minutes,then decreased gradually,90 minutes later dropped to normal level.When priming with nimodipine,the axonal inhibition by Nogo-A was partly abrogated compared with control.Conclusion Ca~(2+) may participate in the signal transduction of Nogo-A inhibiting axonal outgrowth.

To evaluate the effect of wild-type p53 gene on the growth and radiotherapeutic sensitivity of human glioma cells, plasmid PC53-SN3 carrying wild-type p53 gene was transfected into U251 cells. p53 gene expression in transfected cells was detected by RT-PCR, and the cell growth inhibition and apoptosis in the absence or presence of irradiation were assessed by MTT and flow cytometry. The transfection of p53 gene into U251 cells was confirmed by RT-PCR. MTT showed that p53 gene alone induced strong inhibitory effect on the growth of U251 cells (inhibition rate (IR), (79.60 +/- 5.69)%). The killing effect of irradiation alone on U251 cells was not strong (IR: (17.06 +/- 4.35)% (17.39 +/- 1.67)% (18.73 +/- 4.68)%) and increased with the irradiation doses (3, 6, 9 Gy). When combined treatment of wild-type p53 gene transfection and irradiation was used, the effect was significantly increased (IR:(80.60 +/- 5.35)%. (90.30 +/- 1.67)%, (91.30 +/- 2.01)%). The apoptosis rate of U251 cells induced by p53 gene transfection was 17.38%. The rate induced by irradiation increased (4.61%, 4.84%, 5.40%) with the irradiation doses (3, 6, 9 Gy). The apoptosis rate was also significantly increased (17.80%, 20.03%, 22.34%) after combined treatment of p53 and irradiation with different doses (3, 6, 9 Gy). It is concluded that wild-type p53 gene and irradiation could result in synergistic inhibitory effect on the growth of human glioma cells.

Neurology Asia 2017;22(1):69-71
One-and-a-half syndrome with facial diplegia, also referred to as the fifteen-and-a-half syndrome, is an
extremely rare clinical entity caused by involvement of bilateral tegmentum of pons. Herein, we report
a 52-year-old male who presented with one-and-a-half syndrome with left facial paralysis, which was
consistent with the so-called eight-and-a-half syndrome. Brain magnetic resonance imaging showed
pontine infarction. Five days after initiation of antiplatelet therapy, the patient developed right facial
paralysis, a diagnosis of fifteen-and-a-half syndrome was made, repeat MR imaging revealed bilateral
pontine tegmentum infarction. Fifteen-and-a-half syndrome is a newly proposed concept associated
with pontine infarction. The clinicoradiological features of this specific disease are as yet unclear due
to its extreme rarity. The current case would help advance the current understanding of the disease
spectrum of pontine infarction.
