Objective: To observe the clinical effect in the treatment of toothache by puncturing Hegu(LI 4). Methods: Two hundred and seventy-eight cases of the patients were randomly divided into the treatment group (139 cases) and the control group (139 cases). The treatment group was treated by puncturing Hegu (LI 4) with electric stimulation and the control group, by puncturing Chenshan (BL 57) with electric stimulation, for 3 days as one course of the treatment,to grade pain and observe the anesthetic effect respectively. Results: There was no significant difference in the remarkable effective rate between the two groups before withdrawal of the needle in the treatment for one day (P＞0.05). In the other times, the remarkable effective rate was obviously higher in the treatment group than in the control group (P＜0.05). Conclusion:Acupuncture on Hegu (LI 4) is effective in treating toothache.

OBJECTIVETo study the relationship between SNP rs17401966 at the KIF1B gene and the genetic susceptibility to Hepatocellular carcinoma (HCC).

METHODSAll study objects were recruited from two Grade A hospitals of Amoy from January 2011 to October 2014.They were surveyed in individual matching case-control study. Accepting criterias in the cases: HCC was first diagnosed based on diagnostic basis during the investigations, over 18 years old, present addresses were as same as surveyed areas in the district (county) level range, no past history of cancers; Exclusion criterias: patients with other liver diseases. The tumor patients without HCC, patients with autoimmune hepatitis or toxic hepatitis, patients who refused to be investigated or too ill to be investigated. Accepting criterias in the controls: the control who passed the physical examination matched the case in ages (no more than 3 years old), sex, health screening in the same hospital over the same period and district (county); Exclusion criterias: people with liver disease or any history of cancers. This study consisted of 376 HCC patients and 403 controls, 5 ml morning fasting venous blood of all subjects were obtained to isolate cells and distribute genotype. The differences in general information between cases and controls were tested by χ² test and t-test. The association between SNP rs17401966 and the risk of developing HCC were assessed by using the multiple factors logistic regression.

RESULTSThe mean age and standard deviation for case and control groups were (61.7 ± 12.8) years and (60.6 ± 12.7) years (t = 1.15, P = 0.251), respectively. The proportion of family history of cancer [28.7% (108/376)] and the HBsAg positive rate [26.9 % (101/376)] in case group were higher than these in control group [15.9% (64/403), 2.7% (11/403)] (χ² = 18.65, 92.02, P < 0.001). In HBsAg carriers, GG genotype genetic susceptibility to HCC is 0.12 (0.02-0.75) times for AA genotype, and G allele susceptibility to HCC is 0.38 (0.15-0.98) times for A allelc. In HBsAg negative group, it showed no statistical significance in the relationship between SNP rs17401966 and susceptibility to HCC, and compared with the A allele, the risk for HCC of G allele is 0.79 (0.62-1.01).

CONCLUSIONThe results demonstrated that the presence of the GG genotype, the GA genotype and the G allele at rs17401966 of the KIF1B gene might decrease the risk for HCC.

Objective:To investigate the protective effect and mechanism of low-intensity pulsed ultrasound on human periodontal ligament stem cells (hPDLSCs) injured by high glucose.Methods:hPDLSCs were cultured in vitro and randomly divided into normal control group, high glucose model group and three low intensity pulsed ultrasound groups (30, 60, 90 mW/cm 2). Cells in the high glucose model group and three low intensity pulsed ultrasound groups were treated with high glucose medium (glucose 40 mmol/L) for 48 h to establish high glucose model. Cells in the normal control group were treated with normal medium (glucose 11 mmol/L). After modeling, three low intensity pulsed ultrasound groups were treated with low-frequency pulse for 20 min each day for 7 days at a dose of 30, 60 and 90 mW/cm 2 respectively. After 7 days, the proliferation ability of each group was determined by MTT assay. The changes of cell cycle and apoptosis were detected by flow cytometry. The level of Caspase-3, Caspase-6, and Caspase-9 was detected by colorimetry. The levels of Wnt1, Wnt10b and β-catenin genes and proteins were detected by reverse transcription PCR and Western Blot respectively. Results:Compared with the hPDLSCs in the normal control group, the hPDLSCs in the high glucose model group have the following changes except for the cell cycles (all P>0.05), i.e. the activity of the cells was decreased and the apoptosis was increased (all P<0.05), the activities of Caspase-3, Caspase-6, and Caspase-9 were increased (all P<0.05), and the expressions of Wnt1, Wnt10b and β-catenin genes and proteins were decreased (all P<0.05). Compared with the hPDLSCs in the high glucose model group, the hPDLSCs in low-intensity pulsed ultrasound groups have the following changes expect for the cell cycles (all P>0.05), i.e. cell viabilities were increased (all P<0.05), proliferation abilities were increased (all P<0.05), apoptosis rates were decreased (all P<0.05), the activities of Caspase-3, Caspase-6, Caspase-9 were decreased (all P<0.05), and the expressions of Wnt1, Wnt10b and β-catenin genes and proteins were up-regulated ( P<0.05). Among the three low-intensity pulsed ultrasound groups, when the ultrasonic intensity is 90 mW/cm 2, the above-mentioned index changes most obviously (all P<0.05). Conclusions:Low-intensity pulsed ultrasound can significantly alleviate the hPDLSCs damage induced by high glucose, which may be achieved by reducing the activities of Caspase-3, Caspase-6 and Caspase-9, and up-regulating the expression of Wnt1, Wnt10b and β-catenin.

Single-port and reduced-port laparoscopic radical gastrectomy as the innovative surgery for gastric cancer are gradually accepted nowadays,and more attentions are also paid to single-port and reduced-port laparoscopic radical gastrectomy due to its better cosmetic effect,less pain,lower incidence rate of surgical site infection and more advantages in enhanced recovery after surgery.However,in the early stage,the development of single-port and reduced-port laparoscopic radical gastrectomy were facing challenges and obstacles on account of limited surgical skills,the lack of special laparoscopic instruments,laparoscope and multi-port Trocar.In recent years,the dilemma and difficult situations were gradually resolved following by surgical techniques innovation,laparoscopic instruments and facilities improvement.It is believed that single-port and reduced-port laparoscopic radical gastrectomy will have a good prospect and breakthrough in the field of gastric cancer treatment in the future.

Laparoscopic radical surgery for rectal can-cer involves total mesorectal excision (TME), D 3 lymphadenectomy, and pelvic autonomic nerve preservation, the goal of which is trying to achieve completely radical cure for cancer and urogenital function preservation. In the actual operation procedure, the understanding of fascial anatomy in abdominal and pelvic cavity will help us to improve the quality of TME surgery for rectal cancer and to preserve the pelvic autonomic nerves. When entering the pelvic cavity, the identification of fascia propria of mesorectum, visceral fascia, pre-hypogastric nerve fascia, presacral fascia, ligament structures around the rectum and the Denonvilliers′ fascia in front of the rectum will help us to protect the pelvic autonomic nerves and avoid surgical injury. So the authors focus on how to identify the pelvic fascia structure clearly in laparoscopic radical resection for rectal cancer, furthermore, to master the concepts of fascia anatomy to realize TME for rectal cancer and to achieve pelvic autonomic nerve preservation.

Digestive tract reconstruction with side-to-side esophagojejunostomy is one of the most commonly used digestive tract reconstruction methods after laparoscopic total gastrectomy. It does not need an auxiliary incision. The linear stapler is used to directly enter the abdominal cavity through the Trocar to perform side-to-side anastomosis of esophagojejunostomy. The common hole can be closed by hand suture or linear stapler. 4K laparoscopy can present a clearer and more realistic view to the operators, so as to realize side-to-side esophagojejunostomy more accurately, to reduce the postoperative anastomo-tic related complications and improve the safety of the operation. This article will elaborate the technical key points and difficulties of esophagojejunostomy in 4K laparoscopic total gastrectomy, as well as the prevention and treatment of anastomotic related complications.

Objective To explore the impact of clinical treatment decisions on the long-term survival of different molecular subtypes of locally advanced breast cancer(LABC),and to promote the development of more effective and individualized treatment regimens for LABC.Methods The cases of LABC diagnosed by pathology from 2010 to 2015 were searched in the database.Breast cancer-specific survival(BCSS)and overall survival(OS)were estimated by plotting Kaplan-Meier curves.The log rank test(Mantel-Cox)was used to analyze the difference between the groups,and the benefit population of LABC was determined after for age,TNM stage,grade,treatment methods.Results The 5-year OS and BCSS were 77.43％and 84.34％in breast-conserving,and 68.03％and 76.90％in mastectomy,respectively.The 5-year OS and BCSS of Luminal A LABC were 79.91％and 87.23％in breast-conserving,and 71.78％and 81.16％in mastectomy,respectively.The 5-year OS and BCSS of Luminal B LABC were 79.30％and 83.14％in breast-conserving,and were 70.37％and 76.92％in mastectomy,respectively.The 5-year OS and BCSS of triple-negative LABC were 60.77％and 68.13％in breast-conserving,and those of mastectomy were 47.13％and 55.94％,respectively.The 5-year OS and BCSS of HER2 positive were 75.42％,82.05％in breast-conserving,and were 67.05％and 75.01％in mastectomy,respectively;The 5-year OS and BCSS of triple-positive LABC were 86.12％and 91.63％in breast-conserving,and 74.54％and 82.56％in mastectomy,respectively.The 5-year OS and BCSS of well differentiated and N0 triple-positive LABC patients with chemotherapy were 88.24％and 76.91％,and those of patients without chmotherapy were 88.24％and 90.91％,respectively(BCSS:P=0.812;OS:P=0.311).Conclusion In the selective population,OS and BCSS of patients with LABC undergoing breast conserving surgery were significantly better than those of mastectomy.When OS and BCSS were compared for different molecular types and stages of LABC,breast-conserving surgery was still superior to total mastectomy.LABC could be considered for highly differentiated,N0 stage Triple positive without chemotherapy.
