He aha kahi C-peptide
Hāʻawi ke ʻepekema lapaʻau i ka wehewehe i kēia manawa:
- ʻO ka hoʻowalewale ʻana o ka maʻi mellitus o ka maʻi ʻokoʻa a me ka ʻano ʻokoʻa o ka maʻi II a me ke ʻano type II;
- Ka hana ʻana o ka insulinoma (kahi momona paha a malignant o ka pancreas);
- Ka ʻike ʻana o nā koena o ka kaila pancreatic i loaʻa ma hope o kona neʻe ʻana (no ke kanesa o ke kino);
- Diagnosis o ka maʻi ate;
- Diagnosis o ka polycystic ovary;
- ʻO ka nānā aku i nā pae insulin i ka maʻi o ka naʻau;
- ʻO ka loiloi o ka mālama ʻana no ka maʻi diabetes.
Pehea ka C-peptide synthesized ma ke kino? ʻO Proinsulin, ka mea i hoʻoili ʻia i loko o nā pancreas (ʻoi aku ka pololei, ma ka β-cell a me nā pulupulu pancreatic), he kaula polypeptide nui e loaʻa ana i nā koena asam amino 84. I kēia kūlana, hoʻihoʻi ka waiwai i ka hana hormonal.
ʻO ka hoʻololi ʻana o ka proinsulin ka hana i ka insulin e like me ka neʻe ʻana o ka proinsulin mai nā ribosomola i loko o nā wahi i loko o nā mea i hoʻopaʻa ʻia e nā mea kuʻuna o ka hoʻokaʻawale o nā molekala. Ma ka manawa like, he 33 mau koena o ka waikawa amino, i ʻike ʻia ʻo ka ʻae ʻana o ka peptide a i ʻole C-peptide, e pani ʻia mai kahi kihi o ke kaulahao.
No ke aha e makemake ai au i kahi hoʻokolohua C-peptide?
No kahi ʻike maopopo o ke kumuhana, pono ʻoe e hoʻomaopopo i ke kumu e hana ai nā limahana o ka C-peptide, a ʻaʻole ma ka insulin maoli.
- ʻO ka hapalua o ke ola o ka peptide i ke kahe koko e ʻoi aku ka lōʻihi ma mua o ka insulin, no laila ua paʻa ka hōʻailona mua;
- ʻO ka loiloi immunological no C-peptide hiki iā ʻoe ke ana i ka helu ʻana o ka insulin a hiki ke kū i ke kua ʻana o ka noho ʻana o ka lāʻau lapaʻau synthetic i loko o ke koko (ma nā ʻōlelo olakino - ʻaʻole i hele a "C-peptide" me insulin);
- Hāʻawi ka loiloi no C-peptide i kahi loiloi kūpono o ke kiʻekiʻe o ka insulin a hiki i ke alo ʻana o nā antibimies autoimmune i loko o ke kino, ka mea e tupu ai i nā mea maʻi me ka maʻi diabetes type II.
Me ka exacerbation o ka maʻi mellitus o ka maʻi mellitus (ʻoi aku ka ʻano I), he haʻahaʻa nā kiko o C-peptide i loko o ke koko: ʻo ia kahi hōʻike mau no ka nele o ka insulin endogenous (loko). ʻO ka haʻawina o ka ʻike ʻana o ka peptide pili i hiki i ka loiloi ʻana o ka huna ʻana o ka insulin i nā kūlana kulekele.
Pehea ka loiloi o C-peptide
Lawe ʻia kahi hōʻike koko no ka C-peptide ma kahi ʻōpū ʻole, ke ʻole kahi alakaʻi kūikawā mai ka endocrinologist (pono e nīnau ʻia kēia loiloi inā āu i manaʻo ai i kahi maʻi metabolic). ʻO ka manawa o ka wikiwiki ma mua o ka hāʻawi ʻana i ke koko he 6-8 mau hola: ʻo ka manawa maikaʻi loa no ka hāʻawi ʻana i ke koko i ke kakahiaka ma hope o ke ala ʻana.
ʻAʻole ʻokoʻa nā ka hoʻāʻo ʻia ʻana o ke koko mai ka mea maʻamau: ʻiʻoki ʻia ka vein, hoʻākoakoa ʻia ke koko i kahi ʻōpala ʻole. Inā hematomas puka ma hope o venipuncture, kuhikuhi ke kauka i kahi mea hoʻomehana mahana. Holo ʻia ke koko lawe ʻia ma kahi centrifuge, hoʻokaʻawale i ka serum, a ʻōeloʻi, a ʻike ʻia i loko o ka hale hana ma lalo o kahi mikroscope e hoʻohana ana i nā reagents.
E like me nā mea e hoʻoulu ai, hiki ke hoʻopili ʻia nā ʻano hana penei:
- Kui o kahi insulin antagonist - glucagon (no nā kānaka me ka hypertension, ua hoʻohālikelike ʻia kēia hana;
- ʻO ka pāʻina maʻamau ma mua o ka hoʻoilo ʻana (e ʻai wale ʻia nā ʻāpana "ʻai liʻiliʻi").
ʻO kahi koho kūpono no ka maʻi maʻi ke hana ma kahi o nā hōʻike 2:
- ka helu ʻai wikiwiki
- hoʻoulu.
I ka nānā ʻana i kahi ʻōpū ʻole, hiki iā ʻoe ke inu i ka wai, akā, pono ʻoe e hōʻalo i ka lawe ʻana i nā lāʻau lapaʻau e hoʻopilikia ai i ka pololei o ka hopena hoʻoili. Inā hiki ʻole ke hōʻoka ʻia nā lāʻau lapaʻau no nā kumu olakino, pono e hōʻike ʻia kēia ʻoiaʻiʻo ma ka palapala ʻōlelo.
He aha nā hōʻailona o ka loiloi no C-peptides
ʻO nā leʻa i ka pae o C-peptide i serum e pili ana i ka dinamics o ka nui o ka insulin i ke koko. ʻO ka ʻenehana peptide wikiwiki e noho ana mai ka 0.78 a i ka 1.89 ng / ml (ma ka ʻōnaehana SI, 0.26-0.63 mmol / l).
No ka ʻikeʻana i ka insulinoma a me kona hoʻokaʻawale ʻana mai ka hypoglycemia wahaheʻe (ʻoiaʻiʻo), ʻo ke ʻano o ka pae o ka C-peptide i ka pae o ka insulin e hoʻoholo.
Inā helu hoʻokahi a emi mai paha kēia waiwai, ʻo ia ka mea i hōʻike ai i ka hoʻonui ʻia o ka insulin o loko. Inā ʻoi aku ka nui o nā kuhikuhi ma mua o ka 1, ʻo ia ka hōʻike o ka hoʻokomo ʻana i ka insulin waho.
Piʻo kiʻekiʻe
- ʻAno maʻi II;
- Insulinoma;
- ʻO ka maʻi Herenko-Cush (maʻi neuroendocrine i hoʻokumu ʻia e ka adrenal hyperfunction);
- ʻO ka holo ʻole o ka pūpū;
- ʻO ka maʻi ʻeha (cirrhosis, hepatitis);
- ʻŌnuʻi lime Polycystic;
- ʻO ke kāne male momona;
- Hoʻohana lōʻihi o ka estrogens, glucocorticoids, nā lāʻau lapaʻau āpau.
Hiki i kahi kiʻekiʻe o C-peptide (a no laila insulin) ke kuhikuhi i ka hoʻomaka ʻana o ka pulu hoʻohaʻahaʻa waha. ʻO ia paha kekahi hopena a kahi maʻi pancreas a i ʻole nā hoʻololi ʻana i nā cell beta.
ʻO ka haʻahaʻa haʻahaʻa
Hoʻolaha ka hoʻohālikelike ʻana me ka pae maʻamau o C-peptide i ka wā e:
- ʻAno maʻi type 1;
- Hoopaea hypoglycemia;
- Hoʻoweliweli ʻoi ka hōʻemi ʻana i ka maʻi pancreatic.
