Objective To compare the effects of different surgical time for the recovery of elderly patients with acute cholecystitis and provide reference for its clinical treatment. Methods Clinic data of 79 elderly patients with acute cholecystitis from January 2008 to September 2013 were analyzed retrospectively. Patients were divided into two groups according to different surgical time, 42 cases having surgery within 72 h as early surgery group, and 37 cases having surgery later than 72h as delayed surgery group then the curative effects of two groups were compared and analyzed. Results The success rate of early surgery group reached 97.6%, and that of delayed surgery group 91.9%, which showed no statistically significant difference (P > 0.05); with shorter operative time, less blood loss, shorter length of hospital stay and less medical cost, patients recovered better in early surgery group than those in delayed surgery group and there were statistically significant differences between two groups (P<0.05), while the postoperative discharge time of two groups had no significant difference (P>0.05).The complication rate of early surgery group was 2.4%, and that of delayed surgery group 18.9%, which indicated statistically significant difference (P<0.05). Conclusions Early surgical treatment for elderly patients with acute cholecystitis has a good therapeutic effect and is beneficial to the early rehabilitation of patients.

The objective of this study was to genetically characterize isolates of Giardia duodenalis and to determine if zoonotic potential of G. duodenalis could be found in stray cats from urban and suburban environments in Guangzhou, China. Among 102 fresh fecal samples of stray cats, 30 samples were collected in Baiyun district (urban) and 72 in Conghua district (suburban). G. duodenalis specimens were examined using light microscopy, then the positive specimens were subjected to PCR amplification and subsequent sequencing at 4 loci such as glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi), beta-giardin (bg), and small subunit ribosomal RNA (18S rRNA) genes. The phylogenetic trees were constructed using obtained sequences by MEGA5.2 software. Results show that 9.8% (10/102) feline fecal samples were found to be positive by microscopy, 10% (3/30) in Baiyun district and 9.7% (7/72) in Conghua district. Among the 10 positive samples, 9 were single infection (8 isolates, assemblage A; 1 isolate, assemblage F) and 1 sample was mixed infection with assemblages A and C. Based on tpi, gdh, and bg genes, all sequences of assemblage A showed complete homology with AI except for 1 isolate (CHC83). These findings not only confirmed the occurrence of G. duodenalis in stray cats, but also showed that zoonotic assemblage A was found for the first time in stray cats living in urban and suburban environments in China.

This study aimed to identify the assemblages (or subassemblages) of Giardia duodenalis by using normal or nested PCR based on 4 genetic loci: glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi), beta-giardin (bg), and small subunit ribosomal DNA (18S rRNA) genes. For this work, a total of 216 dogs' fecal samples were collected in Guangdong, China. The phylogenetic trees were constructed with MEGA5.2 by using the neighbor-joining method. Results showed that 9.7% (21/216) samples were found to be positive; moreover, 10 samples were single infection (7 isolates assemblage A, 2 isolates assemblage C, and 1 isolate assemblage D) and 11 samples were mixed infections where assemblage A was predominant, which was potentially zoonotic. These findings showed that most of the dogs in Guangdong were infected or mixed-infected with assemblage A, and multi-locus sequence typing could be the best selection for the genotype analysis of dog-derived Giardia isolates.
