Gosper i.troduced the functi.ns si.q z and cosq z as q-analogues for the tri.onometri. functi.ns si. z and cos z respecti.ely. He stated a vari.ty of i.enti.i.s i.volvi.g these two q-tri.onometri. functi.ns along wi.h certai. constants denoted by Πqn （n ∈ N）. Gosper noti.ed that all hi. formulas on these constants have more than two of the Πqn. So, i. i. natural to rai.e the questi.n of establi.hi.g i.enti.i.s i.volvi.g only two of the Πqn. i. thi. paper, our mai. goal i. to gi.e examples of such formulas i. only two Πqn.

Background: Pancreati.oduodenectomy(PD) i. the standard curati.e treatment for peri.mpullary tumors. The ai. of thi. study i. to report the i.ci.ence and predi.tors of long-term survi.al( ≥ 5 years) after PD. Methods: Thi. study i.cluded pati.nts who underwent PD for pathologi.ally proven peri.mpullary adenocarci.omas. Pati.nts were di.i.ed i.to 2 groups: group(i. pati.nts who survi.ed less than 5 years and group(i.) pati.nts who survi.ed ≥ 5 years. Results: There were 47(20.6%) long-term survi.ors( ≥ 5 years) among 228 pati.nts underwent PD for peri.mpullary adenocarci.oma. Pati.nts wi.h ampullary adenocarci.oma represented 31(66.0%) of the long-term survi.ors. Pri.ary analysi. showed that favourable factors for long-term survi.al i.clude age years old, serum CEA i.rhoti. li.er, tumor si.e i.e of pri.ary tumor, postoperati.e pancreati. fi.tula, R0 resecti.n, postoperati.e chemotherapy, and no recurrence. Multi.ari.te analysi. demonstrated that CA 19-9 i. = 1.712(1.24 8–2.34 8), P = 0.001], smaller tumor si.e [OR(95% Ci. = 1.335(1.032–1.726), P = 0.028] and R0 resecti.n [OR(95% Ci. = 3.098(2.095–4.582), P i.dependent factors for survi.al ≥ 5 years. The prognosi. was best for ampullary adenocarci.oma, for whi.h the medi.n survi.al was 54 months and 5-year survi.al rate was 39.0%, and the poorest was pancreati. head adenocarci.oma, for whi.h the medi.n survi.al was 27 months and 5-year survi.al rate was 7%. Conclusi.ns: The majori.y of long-term survi.ors after PD for peri.mpullary adenocarci.oma are pati.nts wi.h ampullary tumor. CA 19-9 i.e, and R0 resecti.n were found to be i.dependent factors for long-term survi.al ≥ 5 years.
