發(fā)病機(jī)理
艱難梭菌是由于服用抗生素后，打破了腸內(nèi)菌群的平衡，從而導(dǎo)致艱難梭菌累計(jì)了大量的數(shù)量，產(chǎn)生大量的外毒素A和B。外毒素A由腸道毒素和細(xì)胞毒素組成。外毒素可綁定黏膜細(xì)胞從而導(dǎo)致出血。而外毒素B是一種細(xì)胞毒素，在體內(nèi)外毒素B不能與黏膜細(xì)胞直接綁定，因?yàn)橥舛舅谺只能與破壞的細(xì)胞綁定，導(dǎo)致更大的破壞。大多數(shù)艱難梭菌種屬都產(chǎn)生這兩種毒素，從而在不同時(shí)期產(chǎn)生不同的作用，在初期外毒素A首先與黏膜細(xì)胞綁定，造成初級(jí)的破壞，然后外毒素B進(jìn)而發(fā)揮更大的破壞。
艱難梭菌是主要的院內(nèi)腹瀉的代表，其中通過手，器材和染菌雜物傳播。其芽孢可在環(huán)境中幸存幾年。環(huán)境的檢測(cè)中通?？蓹z測(cè)出艱難梭菌。

此病發(fā)病驟然，右上腹偏

中有劇烈陣發(fā)痛，鉆鑿樣感，患者輾轉(zhuǎn)不安、惡心、嘔吐，可

吐出蛔蟲。發(fā)作間期無疼痛或僅感輕微疼痛。若蛔蟲鉆入肝臟

可引起蛔蟲性肝膿腫，必須及早手術(shù)治療。②胰管蛔蟲癥，多

并發(fā)于膽道蛔蟲癥，臨床征象似急性胰腺炎。③闌尾蛔蟲癥，

多見于幼兒，因小兒闌尾根部的口徑較寬，易為蛔蟲鉆入。其

臨床征象似急性闌尾炎，但腹痛性質(zhì)為絞痛，并嘔吐頻繁，易

鹽水浮聚法可較容易查到蟲卵。近年來常用改良加藤法。該法

蟲卵檢出率較高。由于蛔蟲產(chǎn)卵量大，采用直接涂片法，查一

張涂片的檢出率為80%左右，查3張涂片可達(dá)95%。對(duì)直接涂片陰

性者，也可采用沉淀集卵法或飽和鹽水浮聚法，檢出效果更好

The sudden onset of the disease, right upper quadrant

There are severe pains in the hair, drill-like sense, the patient restless, nausea, vomiting, can be

Spit maggots. There was no or only minor pain during the interictal period. If aphids drill into the liver

Can cause ampullous liver abscess, must be treated as soon as possible. 2 pancreatic duct echinococcosis, many

Concurrent with biliary ascariasis, clinical signs resemble acute pancreatitis. 3 appendicitis,

More common in young children, because the caliber of the pediatric appendix roots is relatively wide, it is easy for the locusts to drill. its

The clinical signs are similar to acute appendicitis, but the nature of the abdominal pain is angina and vomiting is frequent and easy.

Perforation occurs, and early surgical treatment is recommended. Check 1. Etiology check fecal smear or

Saltwater flocculation method can easily find eggs. In recent years, the improved Kato method has been used. The law

The detection rate of eggs is high. Due to the large amount of eggs laid by aphids, direct smear method is used to check

The smear detection rate is about 80%, and 3 smears can reach 95%. Direct smear overcast

For those who have sex, sedimentation egg collection method or saturated salt solution flocculation method can also be used to detect better results.

. 2. Ectopic schistosomiasis caused by the transition of blood larvae and blood whiteness during concurrent infection

Cell and eosinophil count increased. 3. Auxiliary examination of B-mode ultrasound and retrograde pancreaticobiliary duct

Shadows contribute to the diagnosis of ectopic roundworm disease. Mammalian endemic lymphoid organs,

Lymphocytes are assembled. It is bean-shaped and is located on the way of lymphatic vessels.

One of the most important organs for the response. Lymphoid sinus cavity has many lymphocytes and giant

Phagocytes. Lymph fluid from the input lymphatic flow enters the cutaneous sinus and then flows to the medullary sinus.

Finally, the output lymphatic vessels leave the lymph gland.
