Presented in this study were three cases of lung cancer undergoing pulmonary venoplasty. In the 3 patients with central type of carcinoma of lung involving pulmonary vein, the main branch of right superior pulmonary vein and the distal end of the superior-lobe vein were occluded. The root part of the vein of right-middle lobe, plus part of vessel of of right superior vein was resected. The right superior vein was reconstructed by continuous 6-0 Prolene sutures. After the operation, the reconstructed was patent and the surgical margin was tumor-free. Postoperatively, clinical manifestations and plain chest films did not show any signs of venous blockade. The patients were discharged healed 3 weeks after the operation. The technical details of the surgery were presented, the improvements on the basis of traditional methods were discussed and its clinical application was evaluated. It is concluded that pulmonary venoplasty is a safe and feasible operation. Further improvement of the surgery will help conserve more lung tissue and benefit more patients because of expanded indications.

Members of genus Acanthamoeba are widely distributed in the environment. Some are pathogenic and cause keratitis and fatal granulomatous amoebic encephalitis. In this study, we isolated an Acanthamoeba CJW/W1 strain from tap water in Wuxi, Jiangsu Province, China. Its 18S rDNA was sequenced and a phylogenetic tree was constructed. The isolated cysts belonged to morphologic group II. Comparison of 18S rDNA sequences of CJW/W1 strain and other isolates showed high similarity (99.7%) to a clinical isolate Asp, KA/E28. A phylogeny analysis confirmed this isolate belonged to the pathogenic genotype T4, the most common strain associated with Acanthamoeba-related diseases. This is the first report of an Acanthamoeba strain isolated from tap water in Wuxi, China. Acanthamoeba could be a public health threat to the contact lens wearers and, therefore, its prevalence should be monitored.

Zuoguiyin, which first recorded in Jingyue Quanshu written by ZHANG Jiebin in the Ming dynasty, was included in the Catalogue of Ancient Famous Classical Formulas(The Second Batch). This study followed the Principles of Textual Research on Key Information of Ancient Famous Classical Formulas to determine the key information of Zuoguiyin in ancient and modern literature, such as the formula origin, the composition of the formula and the origin of the drugs. It was found that the composition, dosage, preparation and processing methods of Zuoguiyin were basically the same as the original formula. The original dosage of this formula is 41.03 g of Rehmanniae Radix Praeparata(the fresh or dried tuberous roots of Rehmannia glutinosa, processed by wine stewing or wine steaming), 7.46 g of Dioscoreae Rhizoma(the dried rhizomes of Dioscorea opposita), 7.46 g of Lycii Fructus(the dried mature fruit of Lycium barbarum), 3.73 g of Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(the dried roots and rhizomes of Glycyrrhiza uralensis, processed by honey-roasted method), 5.595 g of Poria(the sclerotium of Poria cocos), 5.595 g of Corni Fructus(the dried mature fruit pulp of Cornus officinalis). The method of administration is to add 600 mL of water to all the herbs, decoct to 140 mL and take before meals. The function of Zuoguiyin is to nourish Yin and tonify the kidney, and it is often used in the treatment of lumbar soreness and ejaculation, night sweating, dry mouth and throat, thirst and desire to drink, glossy red tongue, thin and rapid pulse, etc. Since ancient times, Zuoguiyin has been used to treat a variety of internal and gynaecological diseases as well as diseases of the nervous, circulatory and reproductive systems that are predominantly caused by kidney Yin deficiency. However, there is not much research on the modern application and therapeutic mechanism of this formula, and there is no standardized preparation in the market, so the degree of development and utilization is not high, and there is still a lot of room for research.
