BACKGROUND:Umbilical cord stem cel s mainly derive from ful-term infants, and common culture methods include tissue-attached method and trypsin-digestion mehod. However, effects of different culture methods on the separation of umbilical cord mesenchymal stem cel s remain many disputes. OBJECTIVE:To observe the effects of different culture methods on umbilical cord mesenchymal stem cel s. METHODS:Umbilical cords of 30 healthy ful-term and caesarean delivery infants were selected, and cultured using tissue-attached method or trypsin-digestion method to isloate and culture human umbilical cord mesenchymal stem cel s. Meanwhile, cel growth was measured by flow cytometry. RESULTS AND CONCLUSION:The fusiform-shaped cel s began to separate from the umbilical cord tissue that was primary cultured using tissue-attached method, and 10 days later, the cel fusion reached 80%;after the umbilical cord was cultured using col agenase-trypsin digestion for 5 days, a smal amount of adherent cel s with different shapes appeared, and the fiber-like cel s reached 80%of confluence until 2-week culture. There was no significant difference in the growth of umbilical cord mesenchymal stem cel s cultured by different culture methods (P>0.05). Moreover, cel s cultured by two methods were al positive for CD13, CD29, CD44 and CD105. These results demonstrate that human umbilical cord mesenchymal stem cel s exhibit a high success rate in primary culture using tissue-attached method, which is superior to the trypsin-digestion method.

Objective:To study retention force durability of root-type attachments.Methods:Five magnetic attachments(Magfit EX-600),semi-precise stud-type attachments(Bedent) and precise stud-type attachments(Dalbo-classic) were fixed on a thermal-cycling and mechanical-loading machine respectively.The retention force of each attachment was measured at the baseline and after every 1,000 cycles of seating-removing.Results:The average retention force of magnetic attachments was(3.85?0.107) N at the baseline which attenuated for 3.38% after 10,000 cycles;The retention force of semi-precise group was(14.10?0.144) N originally and decreased 90.06% of the original force after 10,000 cycles.The primary force of the precise group was 33.14 N and was adjusted to(11.95?0.082) N as baseline attenuating for 74.56%.Conclusion: The retention force of magnetic attachments is lower than the stud attachments but is stable for 10 years.The retention force of stud-type attachments is larger at the baseline but reduced rapidly.

Objective To investigate the distribution of CD14C ( 260)T single nucleotide polymorphism (SNP) in the Han population in Chongqing and to test the reliability with this random sample in genetic research. Methods Single round Touchdown PCR (TD PCR) and restriction fragment length polymorphism (RFLP) method were used for genotyping in 110 people from the Han population in Chongqing. Results Frequencies of TT, CT, and CC genotypes were 43 6%, 39 1%, and 17 3%, respectively. The sample distribution was accorded with Hardy Weinberg principle. Conclusion CD14C( 260)T SNP was found in the Han population in Chongqing, and the distribution of alleles was significantly different from that in white population. The sample from an H W equilibrium population can be used in the association study of the systematic inflammatory reaction in the Han population in Chongqing.

OBJECTIVE:To provide policy recommendations for improvement of the pooled medicines procurement policy through legal analysis. METHODS:The pooled medicines procurement policies in China were reviewed and compared with related laws and regulations to analyze the problems and put forward recommendations. RESULTS:For the pooled medicines procurement policy,there were several conflicts between it and the Bidding Law,Government Procurement Law,Anti-monopoly Law and An-ti-unfair Competition Law. In terms of the pooled medicines procurement institution,there were conflicts between it and Bidding Law,Government Procurement Law. In terms of the price-volume linkage and the main body of tendering,there were conflicts be-tween it and the Bidding Law. In terms of the organization and participants,there were conflicts between it and the Anti-monopoly Law and Anti-unfair Competition Law. CONCLUSIONS:The pooled medicines procurement system should rationalize the main body of tendering,insist on volume secured procurement and price-volume linkage,establish reasonable incentive mechanism through supporting heath system reform policies,eatablish and perfect modern government principles in the field of medicines regulation. The pooled drug procurement policy should be moderately adjusted to follow the above laws in order to raise the procurement efficiency.

Objective:To explore the rehabilitation effect and safety of laparoscopic herniorrhaphy through different approaches in the treatment of inguinal hernia.Methods:The clinical data of 132 patients with inguinal hernia in Shushan Branch of Hefei First People′s Hospital from January 2018 to May 2020 were retrospectively analyzed. Laparoscopic herniorrhaphy was performed in all patients. The 46 patients who were treated with transabdominal preperitoneal patch (TAPP) repair were included in TAPP group, while another 86 patients who were treated with totally extraperitoneal patch implantation (TEP) were included in TEP group. The surgery-related indexes, influencing indexes of pneumoperitoneum on pathophysiology, inflammation indexes, pain score and postoperative complications were compared between 2 groups.Results:There were no significant differences in intraoperative blood loss, recovery time of gastrointestinal function, hospitalization time and non-surgery cost between 2 groups ( P>0.05). The operation time, leaving bed time and surgery cost in TEP group were significantly lower than those in TAPP group: (45.08 ± 4.92) min vs. (51.03 ± 5.62) min, (20.93 ± 2.64) h vs. (22.98 ± 2.01) h and (6 887 ± 603) yuan vs. (8 276 ± 813) yuan, and there were statistical differences ( P<0.01). Before pneumoperitoneum, at 10 min after pneumoperitoneum and after extubation, there were no significant differences in levels of total carbon dioxide (TCO 2), partial pressure of carbon dioxide (PaCO 2), partial pressure of oxygen (PaO 2) and bicarbonate radical between 2 groups ( P>0.05). Before and after surgery, there were no significant differences in interleukin (IL)-6, IL-10 and C-reactive protein (CRP) between 2 groups ( P>0.05). At 1, 3 and 7 d after surgery, there were no significant differences in visual analogue scale (VAS) between 2 groups ( P>0.05). There was no significant difference in the total incidence of complications between 2 groups ( P>0.05). Conclusions:Both TAPP and TEP are safe and effective in the treatment of inguinal hernia. The surgical cost of TEP is relatively lower, and operation time and leaving bed time are shorter. The choices of clinical surgical methods should base on surgeons′ experience and individualized features of patients.
