Try something like this

CREATE TABLE #Table1
    ([uid] int, [name] varchar(4), [diseaseid] int, [intensity] varchar(4))
;

INSERT INTO #Table1
    ([uid], [name], [diseaseid], [intensity])
VALUES    (1, 'xxxx', 2, 'low')
    (1, 'xxxx', 1, 'high'),

;

SELECT MAX([uid]) AS [uid]
       ,MAX([name]) AS [name]
       ,MAX([diseaseid1]) AS [diseaseid1]
       ,MAX([intensity1]) AS [intensity1]
       ,MAX([diseaseid2]) AS [diseaseid2]
       ,MAX([intensity2]) [intensity2]
FROM 
(
    SELECT [uid], [name]
    , CASE WHEN rn=2 THEN NULL ELSE [diseaseid] END AS [diseaseid1]
    , CASE WHEN rn=2 THEN NULL ELSE [intensity] END AS [intensity1]
    , CASE WHEN rn=1 THEN NULL ELSE [diseaseid] END AS [diseaseid2]
    , CASE WHEN rn=1 THEN NULL ELSE [intensity] END AS [intensity2]
    FROM
    (
        SELECT [uid], [name], [diseaseid], [intensity], 
        ROW_NUMBER() OVER(PARTITION BY [uid] ORDER BY Name) AS rn
        FROM #Table1
    ) T
) T
GROUP BY [uid], [name]
