AIM To investigate the effect of DO C(deoxycholic acid) on the absorption of INS-PLA-NP[insulin-loaded poly(lactic acid) nanoparticles] in different sites of gastrointestinal tracts. METHODS After INS-PLA-NP that contained or did not contain DOC was adminitered to different sites in gastrointestianl tracts(stomach, small intestine and colon)of normal rats, the hypoglycemic effect was observed. RESULTS The hypoglycemic effect did not exist after intragastric administration of INS-PLA-NP whether or not DOC was added. The alleviatory hypoglycemic effect was evident after intraintestinal absorption of INS-PLA-NP. After DOC was added, the absorption of INS-PLA-NP was accelerated obviously and the hypoglycemic effect was strengthened significantly. Glucose levels hardly changed after INS-PLA-NP was administered to colon. With the use of DOC, a little hypoglycemic effect appeared. CONCLUSIONS The absorption of INS-PLA-NP in small intestine was accelerated and enhanced by DOC. DOC could be used as absorption enhancer of INS-NP in the future.

PURPOSE: This study was to prepare the basic data for prevention of colo-rectal cancer and protection against its spread. METHOD: The subjects for the study were 204 patients with colo-rectal cancer from the G.S. wards of five general hospitals in Busan for the period of June 1 to September 1, 2001. The instrument used was a questionaire which was developed by Junho Shin(1995). The data was analyzed by descriptive statistics, McNemar test, x2 test, paired t-test, and ANOVA. RESULT: 1. 57% of the studied subjects were male, 42.7% were more than 60 years old, 54.9% were of standard physique, 49.5% were the Buddhists, 50.5% were the middle or high school graduates, 83.8% were city dwellers, 48% were jobless, 69.6% had no-history of alimentary disease, 44.1% had no-family history of cancer, 82.8% were married. 2. Constipation(x2=36.45, p=0.0001) in clients showed a significant positive association for the pre- diagnosed, but diarrhea(x2=3.947, p=0.047) showed a significant positive association for the post-diagnosed. The preference for high seasonings(t=6.23, p=0.0001) and animal fat (t=8.35, p=0.0001) was higher significantly in the pre-diagnosed, but physical activities(x2= 30.22, p=0.0001), an eutrophic or tonic medicine(x2=30.22, p=0.0001), was of and vegetables(t=-6.20, p=0.0001) was higher significantly in the post-diagnosed. 3. There were significant differences in the life style of the pre-diagnosed according to the general characteristics except religion. CONCLUSION: Results of the above study reveal we should be very sensitive to the change of defecation styles and consider the necessity of improving life styles as regards eating habits. When an education program is developed, the general characteristics of the subjects need to be considered.

To verify the effect of echinacoside on replication and antigen expression of hepatitis B virus (HBV) by using HBV-transfected HepG2. 2. 15 cells as the in vitro model. The ELISA method was used to determine HBeAg and HBsAg levels in cellular supernatants. The effect of echinacoside on HBV replication was studied by using HBV transgenic mice as the in vivo model. First of all, the HBV DNA level in hepatic tissues was quantified with PCR method. Meanwhile, the serum transaminase levels and hepatic pathological changes were also evaluated. Subsequently, HBV transgenic mice were divided into five groups: the control group, the lamivudine group (50 mg · kg(-1)) and echinacoside high, medium and low dose group (50, 25 and 12.5 mg · kg(-1)). The mice were orally administered with drugs once per day for 30 days. At the 31st day, the mice serum was separated to measure HBsAg, HBeAg and HBV DNA. Additionally, the liver HBV DNA level and histopathological change were detected. The results indicated that echinacoside at 50 and 100 mg · L(-1) suppressed significantly HBsAg and HBeAg expressions on the sixth day, with the maximum inhibition ratios of 42.68% and 46.29%; And echinacoside at 100 mg · L(-1) also showed an inhibitory effect on HBV DNA. Besides, echinacoside at 50 mg · kg(-1) inhibited significantly HBsAg and HBeAg expressions of HBV transgenic mice, with the inhibition ratios of 42.82% and 29.12%, and reduced markedly the serum HBV DNA level in HBV transgenic mice. In conclusion, the study suggested that echinacoside has a strong effect against HBV replication and antigen expression.

OBJECTIVETo explore the relative factors on the failure in digit replantation in order to take preventions to control the risk factors.

METHODSFrom January 2013 to December 2013, 236 consecutive patients (311 fingers) underwent digit replantation were collected to analyze retrospectively, involving 183 males and 53 females with an average age of 34.5 years old ranging from 2 to 62 years old (6 cases under 6 years old and 230 cases elder than 6 years old). There were 51 thumbs, 87 index fingers, 78 middle fingers, 63 ring fings and 32 little thumbs. Forty cases(forty fings) who were failured as the observation group, the others as the control group. The factors of age, gender, finger, cause of injury, smoking history, ischemia duration, plane of division, condition of venous drainage and condition of arterial repair we assessed.

RESULTSAll 236 cases with 311 fingers were replanted, 40 fingers were failured after operation. The relative factors on the failure in digit replantation included smoking history, cause of injury, plane of division, condition of venous drainage and condition of arterial repair (P< 0.05). There were no significant correlation between the failure and age, gender, finger and ischemia duration (P>0.05).

CONCLUSIONSmoking history, causes of injury, plane of division, condition of venous drainage and condition of arterial repair are risks of failure in digit replantation. Before choosing the type of operation, it should be think about the patient's general conditions, injury status, grasp firmly the operative indications and actively carry out surgical treatment.

Abstract: Objective　To investigate the distribution characteristics of HCV genotypes and subtypes in patients with HIV (human immunodeficiency virus, HIV)/HCV co-infection in Kunming based on the nucleocapsid protein gene sequence of HCV (hepatitis C virus). Methods　Serum was collected from HIV/HCV co-infected patients with household registration in 14 county-level cities, districts and counties under the jurisdiction of Kunming, who admitted to Yunnan Provincial Infectious Disease Hospital from March to August 2019. The viral RNA was extracted from the serum, reverse transcribed to synthesize cDNA, and the HCV nucleocapsid protein gene-specific primers were used for nested PCR amplification. The positive amplification products were sequenced, bioinformatics software such as DNAstar and MEGAX were used for sequence analysis. Results　A total of 64 samples from co-infected patients with clinical diagnosis of suspected HIV/HCV were collected and amplified by HCV nucleocapsid protein gene-specific primers, of which 17 samples were amplified positively. The results of sequence analysis showed that the sequences of 9 cases were located in the same evolutionary branch as the HCV 3b subtype sequence, and the nucleotide homology was 93.3%-95.2%; the sequences of 5 cases were located in the same evolutionary branch as the HCV 1b subtype sequence, and the nucleotide homology was 96.8%-97.6%; the sequence of one case and the subtype sequence of HCV 3a gene were located in the same evolutionary branch, and the nucleotide homology was 95.2%; the sequence of one case and HCV 6n gene subtype sequence were located in the same evolutionary branch, and the nucleotide homology was 97.9%; One case was located in the same evolutionary branch as the HCV 6u gene subtype sequence, and the nucleotide homology was 98.4%. Conclusions　HCV 1b, HCV 3a, HCV 3b, HCV 6n and HCV 6u genotypes or subtypes of HCV are prevalent in Kunming, and HCV 3b is the most prevalent genotype.

Esmolol is a cardioselective beta-blocker with a very rapid onset of action and a short half-life. Labetalol is a combined alpha- and beta-adrenoceptor blocking agent. It is a nonselective antagonist at beta-adrenoceptors and a competitive antagonist of postsynaptic alpha 1-adrenoceptors. A 51 year old female patient was transferred to the operating room for performing spinal fusion under general anesthesia. She had no operation and medication history. The initial heart rate was 150 beats/min. Despite administering several bolus injections of esmolol, the heart rate was not decreased to under 130 beats/min. But the heart rate was decreased to 100 beats/min after the administration of labetalol 5 mg and this rate was maintained without an additional injection. The vital signs were stable until the operation was finished and the patient recovered uneventfully in the recovery room. The postoperative laboratory findings revealed that she had hyperthyroidism. We report here on an anesthetic experience of effective labetalol treatment for esmolol-resistant tachycardia in a patient who was under general anesthesia.

BACKGROUND: We studied the hemodynamic changes induced by pneumoperitoneum and a reversed Trendelenburg in elderly patients with increased cardiac risk (ASA class III; n = 30; age 70.8 +/- 4.9 years, mean +/- SD) and compared the results with elderly patients at normal risk (ASA class II; n = 30; age 69.2 +/- 4.1 years) during laparoscopic cholecystectomy. METHODS: The transesophageal Doppler monitor was performed after induction of general anesthesia (pre-incision), after onset of pneumoperitoneum (insufflation), after head-up (20degrees) and a left lateral tilt (15degrees) (reversed Trendelenburg) and after deflation and horizontal position (desufflation). Mean arterial pressure (MAP), heart rate, cardiac index (CI) and systemic vascular resistance (SVR) were measured, respectively. RESULTS: Induction of pneumoperitoneum and head-up tilt in patients with cardiac risk resulted significantly in a decrease in CI and an increase in SVR compared with patients with normal risk (P < 0.05), and that remained until deflation, but no interval changes in MAP and heart rate. The CI, MAP and heart rate decreased and SVR increased significantly in patients with cardiac risk compared with patients with normal risk before incision (P < 0.05). No complications occurred. The results indicate that pneumoperitoneum and a reversed Trendelenburg are associated with significant but relatively benign hemodynamic changes. CONCLUSIONS: Anesthesia for laparoscopic cholecystectomy in elderly patients with increased cardiac risk should be performed with an adequate hemodynamic monitoring.

OBJECTIVETo compare therapeutic effects of acupuncture at pain points and massage combined with medicine on myofascial pain syndrome (MPS).

METHODSOne hundred and fifty cases were randomly divided into an observation group (n=90) and a control group (n=60). The observation group was treated with needle-sticking method combined with single-finger meditation pushing therapy at pain points, and the control group with local application of Votalin Emulgel combined with Tuina. All the patients were treated for 1 course and followed up after 3 months and their therapeutic effects were compared.

RESULTSThere were significant differences in cumulative scores of symptoms before and after treatment in the two groups (both P < 0.01), and there were no significant differences in the pain and pressure pain between the two groups (P > 0.05), and there were significant differences in the muscle spasm and joint range of motion between the two groups (P < 0.05); after treatment, the markedly effective rate and the total effective rate in the observation group were 57.8% and 94.4% respectively, and were 31.7% and 73.3% respectively in the control group, with a significant difference between the two groups (both P < 0.05).

CONCLUSIONNeedle-sticking method combined with single-finger meditation pushing therapy at pain points can effectively alleviate pain and pressure pain in the patients with MPS and it has better therapeutic effect in the markedly effective rate and the total effective rate as well as improvement of muscle spasm and joint range of motion than local application of Votalin Emulgel combined with Tuina.
