This article expounds the formation,connotation and development of the etiology theory in TCM.By analyzing the deficiency of the existent etiology theory in TCM,we proposed that the essence of the etiology theory in TCM should be studied based on the concept of unification of human and nature.With the guidance of the concept of unification of human and nature,the etiology theory in TCM could be formed an integrated theory.The classification of etiology in TCM which includes basic etiology,secondum etiology and developing etiology was proposed,which makes the etiology theory system in TCM more scientific and logical.

Objective:To study the effects of different Epstein-Barr virus (EBV) DNA load, induction chemotherapy+ radiotherapy and concurrent radiochemotherapy on patients with stage Ⅲ nasopharyngeal carcinoma (NPC).Methods:A total of 178 patients with stage Ⅲ NPC were selected as the study subjects in the Department of Otorhinolaryngology of the First People′s Hospital of Xianning of Hubei Province from January 2012 to March 2019, including 44 patients received adjuvant chemotherapy. According to the pre-treatment EBV DNA load of 1 000 copies/ml, the patients were divided into high viral load group (EBV DNA≥1 000 copies/ml, n=53) and low viral load group (EBV DNA<1 000 copies/ml, n=125), and 14 patients in the high viral load group and 30 patients in the low viral load group received adjuvant chemotherapy. According to treatment method, the patients were divided into induction chemotherapy+ radiotherapy group ( n=105) and concurrent radiochemotherapy group ( n=73). The general clinical data, recurrence rate, 5-year overall survival (OS) rate, disease free survival (DFS) rate, local recurrence free survival (LRFS) rate and disease metastasis-free survival (DMFS) rate of each group were compared. Results:Among 178 patients with stage Ⅲ NPC, 34 cases recurred, accounting for 19.10%, and 29 cases died, accounting for 16.29%. There was a statistically significant difference in N staging between the induction chemotherapy+ radiotherapy group and the concurrent radiochemotherapy group ( χ2=6.40, P=0.01). The tumor recurrence rate in the high viral load group was 33.96% (18/53), and that in the low viral load group was 12.80% (16/125), and there was a statistically significant difference ( χ2=10.79, P<0.01). The recurrence rate of lymph nodes [(9.43% (5/53) vs. 1.60% (2/125), χ2=4.15, P=0.04], the distant metastasis rate [18.87% (10/53) vs. 5.60% (7/125), χ2=7.59, P=0.01] were significantly higher than those in the low viral load group, and there were statistically significant differences. The tumor recurrence rate of patients in the induction chemotherapy+ radiotherapy group was 17.14% (18/105), and that in the concurrent radiochemotherapy group was 21.91% (16/73), and there was no statistically significant difference ( χ2=0.63, P=0.43). The 5-year OS rate, DFS rate, LRFS rate and DMFS rate of 178 patients with stage Ⅲ NPC were 84.68%, 72.80%, 79.68% and 79.54%, respectively. The 5-year OS rate (79.25% vs. 92.80%, χ2=6.86, P<0.01), DFS rate (73.58% vs. 88.00%, χ2=5.67, P=0.01), LRFS rate (73.21% vs. 89.24%, χ2=8.32, P<0.01) and DMFS rate (65.24% vs. 78.00%, χ2=4.15, P=0.02) in the high viral load group were significantly lower than those in the low viral load group, and there were statistically significant differences. The 5-year OS rate (89.52% vs. 87.67%, χ2=0.15, P=0.70), DFS rate (84.76% vs. 82.19%, χ2=0.21, P=0.65), LRFS rate (80.38% vs. 79.84%, χ2=0.00, P=1.00) and DMFS rate (79.52% vs. 81.78%, χ2=0.05, P=0.83) in the induction chemotherapy+ radiotherapy group were not statistically significant compared with those in the concurrent radiochemotherapy group, and there were no statistically significant differences. The 5-year OS rate of 44 patients receiving adjuvant chemotherapy was significantly higher than that of patients who did not receive adjuvant chemotherapy (93.77% vs. 87.49%), and there was a statistically significant difference ( χ2=5.21, P=0.02). In the high viral load group, the 5-year OS rate of patients receiving adjuvant chemotherapy was significantly higher than that of patients who did not receive adjuvant chemotherapy (93.77% vs. 84.13%), and there was a statistically significant difference ( χ2=5.11, P=0.03). Conclusion:Induction chemotherapy+ radiotherapy can achieve the same therapeutic effect as concurrent radiochemotherapy. High viral load is associated with high recurrence rate and poor survival rate. For these patients with high viral load, treatment intensity needs to be strengthened.

Objective:To investigate the clinical efficacy and safety of compound carraghenates suppositories in the treatment of wounds after anal fissure operation. Methods:Eighty-eight cases of patients with anal fistula post-operation wounds were diagnosed from June 2011 to June 2014 and randomly divided into the observation group (n=44) and the control group (n=44). The control group was treated with the conventional treatment and the observation group was treated with external compound carraghenates suppositories additionally. The efficacy, average healing time, growing time of granulation tissue and removal time of necrotic tissue, pain disappear-ance time and wound edema disappearance time after the operation and the area of wound surface in the two groups were observed and compared. Results:After the 14-day treatment, the time of wound healing, granulation growth and cure in the observation group was shorter than that in the control group (P<0. 05). In the observation group, the total effective rate (93. 18%) was higher than that in the control group (77. 27%, P<0. 05). After the 7-day and 14-day treatment, the pain score and wound edema score in the observa-tion group were significantly lower than those in the control group (P<0. 05), and the wound area was significantly smaller than that in the control group (P<0. 05). Conclusion:The clinical efficacy of external compound carraghenates suppositories in the treatment of wounds after anal fissure operation is significant, safe and reliable.

Objective The aim of this study was to compare hypophosphatemia between the sepsis patients and the non-sepsis patients,and between within the subgroups of sepsis patients.Methods We collected 312 sepsis cases and 300 non-sepsis cases by stratified random sampling method yearly.In the sepsis cases,the number infected by gram-negative bacteria was 170,and by gram-positive bacteria was 142,containing 4 different bacteria infected cases in each one.Serum phosphorus of cases in each group were collected.The data were statistically processed to compare the incidence rates of hypophosphatemia,mean serum phosphorus levels and relative risk among groups.Results There was a statistical difference between the sepsis cases and the non-sepsis cases in incidence rate of hypophosphatemia (P ＜ 0.05,and RR ＞ 1.2).There were statistical differences between the cases infected by gram-negative bacteria and the cases infected by the gram-positive bacteria,also among cases infected by 4 different gram-positive bacteria in both incidence rate of hypophosphatemia and average serum phosphorus level (all P ＜ 0.05),and both RR ＞ 1.2.There were no statistical differences among cases infected by 4 different gram-negative bacteria in both incidence rate of hypophosphatemia and average serum phosphorus level (both P ＞ 0.05),and RR ＜ 1.2.Conclusions The sepsis patients were susceptible to hypophosphatemia,especially the ones infected by the 4 gram-negative bacteria,staphylococcus aureus and enterococcus in this study.We should pay attention to the serum phosphorus level seriously and prevent the occurrence of serious complications.

Objective To investigate the effect of dexmedetomidine on emergence agitation (EA) following sevoflurane anesthesia in children with cerebral palsy.Methods Fifty ASA physical status Ⅰ or Ⅱ children with cerebral palsy of both sexes,aged 2-12 yr,scheduled for elective muscle strength muscle tension adjustment method,were randomly allocated into 2 groups (n =25 each):control group (group C) and dexmedetomidine group (group D).Anesthesia was induced with iv injection of sufentanil 0.3 μg/kg,cisatracurium 0.15 mg/kg,and propofol 1.5 mg/kg.The patients were tracheal intubated and mechanically ventilated.Dexmedetomidine 0.5 μg/kg was intravenously infused over 15 min after induction of anesthesia in group D and the equal volume of normal saline was given in group C.The operation was begun at the end of administration.Anesthesia was maintained with inhalation of 2％-4％ sevoflurane and the concentration was adjusted to achieve a target BIS value of 45-60.The heart rate,systolic blood pressure and diastolic blood pressure were recorded before infusion of dexmedetomidine (T1) and at skin incision (T2).The extubation time,emergence time and consumption of sevoflurane were also recorded.The end-tidal sevoflurane concentration was recorded at T1,T2,and the end of operation (T3).The adverse cardiovascular events and occurrence of EA were also recorded.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.The peripheral venous blood samples were collected at T1,T2,T3 and extubation (T4) for determination of the blood glucose level and serum cortisol concentration.Compared with group C,the emergence time and extubation time were significantly shortened,and the consumption of sevoflurane,end-tidal sevoflurane concentrations at T2 and T3,PAED scores,incidence of agitation,and the blood glucose level and serum cortisol concentration at T4 were significantly decreased in group D (P ＜0.05 or 0.01).There was no significant difference in the incidence of bradycardia or heart rate,systolic blood pressure and diastolic blood pressure at each time point between the two groups (P ＞ 0.05).Conclusion Dexmedetomidine can decrease the development and degree of EA following sevoflurane anesthesia in children with cerebral palsy.

AIM To evaluate whether l glutamine monofluorophosphate(MFP) together with Alendronate sodium may further increase bone mass in ovariectomized rats. METHODS Forty two 3 month old Sprague Dawley female rats were randomized into six groups:group 1 rats were sham operated(Sham),group 2 rats were ovariectomized controls(Ovx),and groups 3～6 were ovariectomized and received either 1 mg?kg -1 ?d -1 of alendronate sodium ,270 mg?kg -1 ?d -1 of calcium gluconate,5 6 mg?kg -1 ?d -1 of MFP or combination of 5 6 mg?kg -1 ?d -1 of MFP and 1 mg?kg -1 ?d -1 of alendronate sodium for 3 months. All animals received double bone fluorochrome labeling prior to sacrifice. At the end of experiment,the left tibiae were havested for histomorphometrical evaluations. RESULTS Alendronate sodium increased trabecular bone volume significantly with suppressed bone resorption and bone formation. Administrated calcium gluconate had no influence on the bone mass. MFP also could not restore cancellous bone of ovariectomized rats. Administration of both MFP and alendronate sodium increased bone mass significantly but did not increase bone mass compared with alendronate sodium. CONCLUSIONS The results indicated administration of both alendronate sodium and MFP could not further increase bone mass of ovariectomized rats.

The high incidence of postoperative recurrence of hepatocellular carcinoma ( HCC) is a most difficult obstacle for improving the prognosis of patients.Several adjuvant modalities have been developed to prevent recurrence in patients after surgery; nevertheless , there is no consensus regarding the standardized adjuvant therapy in terms of indications , clinical efficacy and interactions.In this article we review the currently available evidence in the medical literature on adjuvant therapy in HCC after radical resection.
